▼ An array antenna consists of a group of radiating elements forming a single aperture to transmit and receive electromagnetic energy. This work focuses on the analysis, development, and design of array antennas geared towards operation over wide frequency bandwidths. As a consequence of the present effort, both the geometry and the operation theory of a louver array antenna are developed, and their use in wide-band antenna arrays investigated.; This dissertation begins by first establishing the electromagnetic boundary condition associated with the radiating aperture of an antenna array made of identical cells. Then, it proceeds to impose this condition on Maxwell's equations to yield the array radiated field as an infinite plane wave spectrum.; To properly investigate the energy transfer efficiency of an array, from circuit to free space, the Poynting theorem is used to determine the power balance equation of the antenna. From this analysis, an aperture reflection coefficient is defined and introduced as a convenient figure-of-merit to gauge the effectiveness of the antenna as an energy transducer. For demonstration purposes, this aperture reflection coefficient is then applied to study the characteristics of the frequently used rectangular microstrip patch array. It is shown that the patch array geometry is prone to excite evanescent fields (i.e., store reactive energy) in its aperture region, causing it to require a highly reactive, and therefore narrow band, matching network behind each element to ensure proper operation. In contrast, the louver array primarily excites a dominant mode field that exactly emulates the desired radiated plane wave, with nearly no evanescent field generation. Since a band-limiting matching structure is not required (to compensate evanescent fields), the louver antenna is inherently wideband. In addition to this fact, the louver antenna is amenable to be integrated directly with semiconductor electronics. This feature allows the future implementation of a densely populated array antenna with fractional wavelength element spacing to enable broad band, wide angle, grating-lobe-free beam scan.; Even though no experimental work was performed for this research, a systematic array design and analysis procedure is presented at the end of this dissertation. To demonstrate their application, a louver array antenna is then designed for a 30-to-1 operation frequency band. As a preliminary validation, this louver array is then modeled using an established commercial finite-element numerical analysis software. Both the analytically and the numerically predicted array performances obtained show close agreement. This validates the design and analysis procedures presented, as well as demonstrate their applicability for implementing high efficiency, wideband, wide scan angle array antennas.

Due to confidential information or other reasons only a part of the publication is presented in the repository. Wideband Class-B power amplifier is required in Modern communication systems. The bandwidth limitation of Class-B Power amplifier is generally caused by the narrow band 2nd harmonic short. In this thesis the methods of 2nd harmonic manipulation in Class-B power amplifier are discussed. In the beginning, the current and voltage waveforms at output of the amplifier are analyzed, and a series of load configurations which can give good performance in Class-B power amplifier is given. In single-ended topology the traditional 2nd harmonic short networks are band limited and interaction between fundamental impedance and 2nd harmonic impedance limited the performance of short networks. Introducing varactors into the short networks the bandwidth of amplifier is extended. Performance of commercial varactor is restricted by the breakdown voltage and package parasitic. A 32% relative bandwidth Class-B power amplifier is realized with the 90 V break down voltage varactors from the Aeroflex central frequency of the amplifier is 1 GHz, the drain efficiency is above 65% over the frequency band. In differential topology the fundamental signal and 2nd harmonic are isolated, which provides convenience for wideband design. In practical design the bandwidth limitation is generally caused by the non-idea transformer in fundamental matching, compensation capacitors are required at primary of transformer. In low power condition, the 2nd harmonic short bandwidth can be extended by using the coupling between primary inductors. Two loops structure is applied in this case. In high power design, the 2nd harmonic is shorted though the large compensation capacitors. One loop structure is applied in this condition. In simulation result these structures can provide 50% to 70% relative bandwidth, which indicates their potential in wideband Class-B design. Advisors/Committee Members: De Vreede, L., Van Rijs, F..

▼ Currently the Doherty Power Amplifier (DPA) is replacing the traditional Class B amplifier in base-station and broadcast applications, as such becoming the preferred choice of industry due to its simplicity and high efficiency performance. In spite of its success, so far practical DPA implementations can provide only a very limited RF bandwidth, which tends to narrow down even more at higher power levels. This narrowband behavior of the DPA is mostly caused by the use of traditional operating classes for the active devices and bandwidth restrictions related to use of a conventional impedance inverter. In this work, the bandwidth of different DPA topologies has been analyzed, followed by a discussion of recent techniques that can help to improve the DPA bandwidth. To overcome the remaining bandwidth limitations in a DPA design, a novel differential configuration was proposed. In this approach, transmission line based baluns are used to implement the desired wideband 2nd harmonic terminations of the active devices. By combining this technique with a novel wideband impedance inverter, excellent DPA wideband performance can be achieved. Unfortunately, when going to practical balun implementations, various imperfections come to light, which trouble the achievable DPA bandwidth performance. For this reason, three practical balun structures are investigated in detail, namely, the coaxial cable based balun, the vertically installed planar balun and suspended planar stripline balun. To explore the proposed DPA concept when using practical baluns, two DPAs featuring mixed-signal driven inputs are presented. A dedicated design procedure for these DPAs is also given. The first prototype is implemented using NXP GaN devices and coaxial cable based baluns. Simulation results show a maximum output power of 52dBm, but in 6dB power back-off we only reach 40% efficiency from 530MHz to 700MHz, which is significantly less than the intend bandwidth (450MHz-810MHz). Using the lessons learned of this first amplifier, a second design with NXP LDMOS devices and suspended planar stripline balun has been developed. According to simulation this later design provides a maximum output power of 59dBm with the efficiency above 55% at both full power and 6dB power back-off. According the simulations this second design can even achieve 50% efficiency at 8dB back-off. The related center frequency is 650MHz with a high-efficiency bandwidth at 6dB power back-off (efficiency within 10% of its maximum) from 460MHz to 790MHz.

peer-reviewed

UltraWideband is a high-speed, short-range and low-power wireless technology. UWB system is overlapped with wireless systems such as WLAN, WiMax and UMTS, which limits the use of UWB. Cognitive radio technology enables the UWB system to efficiently use the overlapped spectrum without causing interference to other wireless systems. The thesis focuses on the design of the cognitive radio resource allocation algorithms for spectrum efficiency maximization in the multiband OFDM UWB system. The spectrum efficiency of a cognitive UWB system depends on the cognitive algorithms used in spectrum sensing, spectrum sharing and spectrum management. The spectrum efficiency maximization problem is formulated to a multi-dimensional knapsack problem with constraints in the transmit power of the UWB subcarriers, the average bit error rate and the interference to the primary users. New cognitive algorithms for spectrum sensing and spectrum management are developed to solve the optimization problem. The proposed low-complexity cognitive algorithms include: primary and advanced power allocation algorithm, group power allocation algorithm and spectrum sensing time optimization algorithm. In a cognitive UWB system, the primary and advanced power allocation algorithm as well as the group power allocation algorithm are used for spectrum management, while spectrum sensing time optimization algorithm is used for spectrum sensing. The spectrum sensing time optimization algorithm computes the optimal spectrum sensing period which maximizes the cognitive UWB system’s data transmission period while guaranteeing a target probability of detection/false-alarm. During the data transmission period, the primary and advanced power allocation algorithm achieves the optimal spectrum efficiency by equally allocating the transmit power and distributing the excessively allocated power to the subcarriers in a greedy manner. Also, the group power allocation algorithm can obtain the optimal spectrum efficiency by adaptively assigning the transmit power to the subcarrier groups according to the effective signal-to-noise ratio of each subcarrier group whose bandwidth is less than the coherence bandwidth of the UWB channel. For energy-limited cognitive UWB system, the proposed cognitive algorithms maximize the spectrum efficiency with lower order-of-growth than the traditional dynamic radio resource allocation algorithms.

▼ Bioengineering is increasingly becoming a cutting edge field of technology thatcombines the state-of-the art in nano technology, microelectronics, wide bandwidth communications, etc. The devices used in bioengineering such as Implantable Medical Devices (IMD)s create a wide variety of new territories for improving quality of life. As these IMDs progressively evolve, boosted by the notable advances in microelectronics and wireless technologies along with the strong demand for precise diagnosis and monitoring of patients, the role of biotelemetry that can wirelessly communicate biological or physiological data from the IMDs is becoming crucially important. In particular, there has been a steady increase in the demand for high data rate transmission in wireless biotelemetry systems with medium to long operation range during the last decade to enable ubiquitous medical services with high precision in diagnosis.The current state-of-the art in biotelemetric systems fall far short of the requirements, however, in terms of data rate and operation range, potentially leading to a faulty diagnosis and resulting severe consequences. Moreover, the relatively large area and high power consumption (tens order of nJ per bit) of conventional transceiver architectures make them even more unfavorable for biomedical applications. The major challenge of the research presented in this thesis is the design of a bi-directional wireless biotelemetry system, for real-time diagnosis characterised by high data rate, low area, low power dissipation, and with a reasonable operating range to take advantage of the benefits of the wireless connection. To cope with these requirements, in this work, to the best of the author's knowledge Ultra-Wideband (UWB) technology is employed for the first time in biotelemetry applications. The UWB approach has inherent strengths due to the impulse transmission nature of the digital baseband signal. These strengths include substantial reductions in hardware complexity and power dissipation without comprising data rates, making UWB highly suitable candidate for biotelemetry applications. In this research work, the focus is on wireless capsule endoscope applications that can transmit medical images with the highest data rate required in biotelemetry systems. The target data rate is 200Mbps to enable real-time transmission of VGA quality high resolution medical images. The optimum architecture in in-vivo applications is proposed as a Differential Transmit Reference (DTR) UWB transceiver that is derived from thorough system modelling and simulations including digital baseband synchronisation. An all digital tunable Pulse Generator (PG) based transmitter to be located inside the capsule is also proposed and implemented in a 0.18um standard Complementary Metal Oxide Semiconductor (CMOS) process.This transmitter achieved impressive results; realising a data rate of 200Mbps with the low power consumption of 27pJ per pulse and the small area of 0.0126mm2 making it optimum for target application of a battery powered device… Advisors/Committee Members: Nooshabadi, Saeid, Electrical and Computer Engineering, Michigan Technological University, Lehmann, Torsten, Electrical Engineering & Telecommunications, Faculty of Engineering, UNSW.

▼ A new Ultra-Wideband (UWB) pattern diversity antenna is proposed, designed and investigated in this thesis. The antenna is capable of radiating in directive and omni-directional modes. Three different versions of the design are studied to show the performance for different applications. The first design consists of a single radiating element fed from two sides by coaxial probes over a shaped ground plane. In-phase excitation of the ports produces omni-directional radiation patterns and out-of-phase excitation results in directive radiation in the boresight of the antenna. The shape of the radiator is a disk, which is modified in geometry to improve the isolation of the ports. The antenna shows impedance bandwidth from 6.8 GHz to more than 15 GHz. The second design is a dual-element version of the same antenna to equalize the radiation patterns in the E- and H-planes. The antenna requires four ports and has an impedance bandwidth from 7.4 GHz to more than 15 GHz. A microstrip power divider is then included, in the third design, which in addition to decreasing the number of extra circuits for feeding, decreases the lower frequency to 4.5 GHz, without changing the radiation patterns significantly throughout the bandwidth. A prototype of this antenna was fabricated and measured, and the results are presented. In the fifth chapter, an electromagnetic polarization filter is designed for the single element UWB antenna, to reduce the cross-polarization level. 7 dB reduction in the maximum level of cross-polarization is achieved, throughout the frequency band 8 - 11 GHz. The following chapter is dedicated to the study and performance of the microstrip-fed UWB antenna, when used as a feed for prime-focus reflectors. It is shown that the designed antenna is capable of feeding the reflector with efficiency as high as 75%, and more than 60%, over a wide bandwidth of 5.5 - 9 GHz.

▼ Tämän opinnäytetyön tarkoituksena oli perehtyä Ultra Wideband -tekniikkaan ja sen tulevaisuuteen ja mahdollisuuksiin. Ultra Wideband eli UWB on langaton tiedonsiirtotekniikka, jonka vahvuuksiin kuuluvat erittäin korkea tiedonsiirtonopeus lyhyillä etäisyyksillä ja pieni energiankulutus. UWB toimii WPAN-verkossa ja se soveltuu erinomaisesti kodin elektroniikan yhdistämiseen langattomasti ja langattoman multimedian siirtoon kuin myös tarkkaan sisätilan paikannukseen. UWB-tekniikka käyttää perinteisiin langattomiin tiedonsiirtotekniikoihin verrattuna erittäin laajaa radiotaajuusaluetta pienellä lähetysteholla. Ultra Wideband -signaali on muiden laitteiden näkökulmasta pelkkää kohinaa, joten tämän vuoksi sitä voidaan käyttää samoilla taajuusalueilla kuin muita tekniikoita. UWB-tekniikan suurin haaste on standardien puute. Mikäli yhteiset säännöt tekniikasta ja taajuuksien jaosta saataisiin aikaan, olisi sille lukemattomia sovellusmahdollisuuksia. Aluksi työssä käydään lyhyesti läpi UWB:n historiaa. Tämän jälkeen siirrytään itse tekniikkaan, jonka lomassa tuodaan ilmi tekniikan vahvuuksia ja haasteita verrattuna muihin langattomiin tiedonsiirtotekniikoihin. Ensimmäiseksi luodaan katsaus UWB:n ominaisuuksiin ja vahvuuksiin yleisesti ja tämän jälkeen siirrytään signaalin määrittelyyn sekä taajuusjako- ja tehotasorajoituksiin. Seuraavaksi käsitellään tekniikan toimintaperiaatteita, toteutusta ja antennin vaatimuksia. Lopuksi pohditaan vielä UWB-tekniikan sovelluskohteita, mahdollisuuksia ja tulevaisuutta.; The purpose of this thesis was to explore Ultra Wideband technology and its future and possibilities. Ultra Wideband, also known as UWB, is a wireless radio technology of which advantages are a very high data transfer rate at short range and small power consumption. UWB operates in wireless personal area network (WPAN) and it is exceptional in connecting consumer electronics and in transferring multimedia. It can also be used as an indoor alternative to Global Positioning System (GPS). Unlike conventional radio technologies, which operate within a relatively narrow bandwidth, the UWB operates across a wide range of the frequency spectrum using low transmit power. Because of the low power it is said that UWB signal is hiding in the noise floor of the spectrum and hence not interfering with the traditional radio systems that operate on the same spectrum. The biggest challenge for Ultra Wideband technology is the absence of standards. If global rules were achieved, UWB would have countless application possibilities. At the beginning the work describes briefly the history of Ultra Wideband. After that the technology itself is explored with its advantages and challenges compared to conventional radio technologies. First there is an overview of the features of the UWB followed by signal specifications, radio frequency spectrum limitations and power restrictions. Next the theory of operation, implementation and antenna requirements are covered. Finally thesis takes a look at the applications, possibilities and…

▼ For over twenty years, global navigation satellite systems like GPS have provided an invaluable navigation, tracking, and time synchronization service that is used by people, wildlife, and machinery. Unfortunately, the coverage and accuracy of GPS is diminished or lost when brought indoors since GPS signals experience attenuation and distortion after passing through and reflecting off of building materials. This disparity in coverage coupled with growing demands for indoor positioning, navigation, and tracking has led to a plethora of research in localization technologies. To date, however, no single system has emerged as a clear solution to the indoor localization and navigation problem because the myriad of potential applications have widely varying performance requirements and design constraints that no system satisfies. Fortunately, recently-introduced commercial ultra-wideband RF hardware offers excellent ranging accuracy in difficult indoor settings, but these systems lack the robustness and simplicity needed for many indoor applications. We claim that an asymmetric design that separates transmit and receive functions can enable many of the envisioned applications not currently realizable with an integrated design. This separation of functionality allows for a flexible architecture which is more robust to the in-band interference and heavy multipath commonly found in indoor environments. In this dissertation, we explore the size, weight, accuracy, and power requirements imposed on tracked objects (tags) for three broadly representative applications and propose the design of fixed-location infrastructure (anchors) that accurately and robustly estimate a tag’s location, while minimizing deployment complexity and adhering to a unified system architecture. Enabled applications range from 3D tracking of small, fast-moving micro-quadrotors to 2D personal navigation across indoor maps to tracking objects that remain stationary for long periods of time with near-zero energy cost. Each application requires careful measurement of the ultra-wideband channel impulse response, and an augmented narrowband receiver is proposed to perform these measurements. The key design principle is to offload implementation complexity to static infrastructure where an increase in cost and complexity can be more easily absorbed and amortized. Finally, with an eye towards the future, we explore how the increasingly crowded RF spectrum impacts current ultra-wideband system design, and propose an alternative architecture that enables improved coexistence of narrowband and ultra-wideband transmissions.

▼ The objective of this research is to design well-tuned, wideband elements for thin planar or cylindrically conformal arrays of balanced elements fed over ground. These arrays have closely spaced elements to achieve wide bandwidths through mutual coupling. This dissertation develops two wideband designs in infinite, semi-infinite, and finite array configurations. The infinite array is best for element tuning. This research advances a concept of a distributed, parallel capacitance between elements and across feeds that must be mutually altered for tuning. Semi-infinite techniques limit the problem space and determine the proper resistive loads to control the low-frequency array-guided surface wave (AGSW). The tight physical placement also forms a periodic structure that, along with the array boundary, launches a wave across the array surface. Options to suppress this surface wave are resistive loading and cylindrical conformations. AGSW control is necessary to achieve a maximum bandwidth, but lower radiation or aperture efficiency results. Conformation is shown to be an ineffective method for AGSW control alone. The Wrapped Bowtie design emerges as a novel design offering nearly a 10:1 bandwidth as a finite array over ground. Some bandwidth comes from the losses in radiation efficiency, which is necessary to control the AGSW; however, its simulated VSWR < 3 bandwidth in an infinite array is 7.24:1 with full efficiency. Less than perfect efficiency is required to mitigate surface wave effects, unless bandwidth is to be compromised. That loss may be as radiation or aperture efficiency, but it is unavoidable if the infinite array bandwidth is to be maintained in finite array designs. Lastly, this research articulates a development path for tightly-coupled arrays that extends in stages from infinite to semi-infinite, and thence finite layouts. Distinctions are explained and defended for the design focus at each stage. Element design, tuning, and initial feed design occur at the infinite array stage; AGSW suppression occurs at the semi-infinite stage; and design confirmation occurs only with the finite array.

Le sujet de cette thèse porte sur la réalisation d'un bloc de transposition de fréquence de 1 à 20GHz à base de composants MEMS. Cette thèse s'est traduite par la conception et la réalisation d'un nouveau type de capacité MEMS RF variable, qui se base sur des structures rotatives de type gyroscope pour l'actionnement, et sur une variation de surface pour la variation de capacité. Comparée à différentes architectures publiées à ce jour, cette structure a l'avantage d'avoir la partie actionnement (la partie MEMS) et la partie RF (la capacité) isolées électriquement, ce qui permet d'éviter le phénomène d'auto actionnement avec la puissance du signal RF traversant. Un autre avantage de la structure développée est la possibilité d'avoir simultanément 8 capacités variables sur une puce unique, avec un seul système d'actionnement. La fabrication de ces puces nécessite l'utilisation d'un wafer SOI pour la partie MEMS et d'un wafer en verre pour la partie RF, ce qui offre la possibilité d'une mise en boitier du MEMS directement pendant le procédé de fabrication. Ces travaux ont également porté sur l'étude du phénomène de pullin dans le cadre des peignes interdigités incurvés (curved combdrive), laissant apparaître les paramètres physiques critiques lors du dimensionnement. Cette étude paramétrique a été utilisée pour améliorer la structure d'actionnement en utilisant des peignes interdigités à largeur de doigt et à gap variable, pour repousser ce phénomène de pullin en dehors de la plage utile d'actionnement. Cette nouvelle capacité variable a ensuite été intégrée dans un système simple d'oscillateur accordable sur alumine pour valider ses performances RF et pourra être associée à un mélangeur pour réaliser le bloc complet de transposition de fréquence

This thesis deals with the realisation of a frequency transposition block from 1 to 20 GHz based on MEMS components. It results in the design and fabrication of a new kind of tuneable RF MEMS capacitor based on a rotational gyroscope structure for the actuation part and on a surface variation for the capacitance change. Compared to other architectures published, this structure presents the advantage to have an actuation part (the MEMS part) and a RF part (the capacitor) that are electrically separated in order to avoid the phenomenon of self-actuation with RF signal crossing power. Another advantage of this structure is the possibility to simultaneously tune 8 different capacitors on a single chip, with only one actuation system. The fabrication of the chips requires the use of a SOI wafer for the MEMS part and a glass wafer for the RF part, which offers on chip packaging opportunity. This work also focused on the study of the pull-in effect in the case of curved comb-drives, highlighting the most critical physical parameters for the design. This parametric study has been used to improve the actuation structure and more particularly the topology of the curved comb-drives by variation of the finger width and gap. These modifications were done in order to push the pull-in…

▼ Recent days, antennas play an important role in wireless communication system. Microstrip patch antennas are well known to have positive features for cost-effective, low profile and broadband. This type of antenna can be used in wide range of applications such as in wireless communications, radar systems, and satellites. Inhibiting characteristics of single patch antenna with low gain and narrow band leads to the research area to have array configuration. Beam steering antennas are the ideal solution for various systems such as traffic control and collision avoidance radar systems. The goal of this work is to design and implement a dual-linear polarization stacked microstrip patch phased array antenna. Single stacked microstrip patch antenna fed by microstrip line was designed to have approximately 3 GHz bandwidth in X-band with another ground plane to form a stripline-fed. Stripline-fed design protects feed lines from any outside effects. The array configuration was adapted to design in order to accomplish beam scan angle of /- 30 degrees by /- 15 degrees. Binomial power distribution of 3x2 array structure was used in order to reduce grating lobes, and changing length of feed lines was implemented for phase shifting. Bowtie cross shape aperture and dual-offset microstrip feedline was used to feed radiating patches. For the feed network, T-split power divider was implemented and optimized to achieve low loss. The length of microstrip line was adjusted to meet desired phase shift that in wideband application, the length of the line had to be long enough to have similar wavelength response over broad frequency range. The antenna array was designed using standard equations and simulated by electromagnetic analysis software called Zealand's IE3D which is method-of-moments based simulator. The resulting measured impedance bandwidth and gain of both microstrip and stripline-fed single antenna are 43 percent and 5 to 10 dBi with low cross polarizations for all frequencies. The array antenna was measured to have 29 to 60 percent impedance bandwidths depending on the different types of beam scan angles. The gain of the array antenna is 8 to 13 dBi, and the beams are directed as required with /- 3 degrees beam scan angle tolerance. The array antenna had a small offset as compared with simulated results because of the fabrication process such as alignment, distorted feed lines while etching, and etc, but the bandwidths and array patterns were acceptable.
