▼ Fundamental TM11 mode of circular microstrip antennas has a limitation of low broadside gain. This thesis explores and investigates the possibility of designing high gain circular microstrip antennas by using higher zeros of the first order mode, or the TM1m modes. Deficiencies in the existing methods of gain enhancement, motivates the need to look for new methods. This is done by first investigating the radiation characteristics of TM1m modes, and then providing techniques for sidelobe suppression in their radiation patterns. Several approaches are proposed and corresponding to each developed technique, an example of high gain antenna is designed, fabricated and experimentally evaluated. First, through the radiation characteristics of a magnetic loop over an infinite ground plane, we explain the occurrence of high sidelobes in the E-plane radiation patterns of the TM1m modes. By noting the peak directivity and sidelobe variation with loop size, we propose, investigate and demonstrate the use of high permittivity substrates to reduce the sidelobes in the TM12 mode. Second, to remove the dependence of the radiation characteristics on high permittivity substrates, another technique to suppress the high sidelobes of TM12 mode, is presented. It is found that introducing a narrow nonresonant rectangular slot at the patch center, sidelobes of the TM12 mode can be effectively suppressed. Sidelobe level (SLL) suppression is demonstrated by both simulation and measurement, using various configurations. Third, it is proposed that linearly superimposing the radiation fields of either odd or even zeros of the first order mode, can achieve both high gain and low sidelobes. To show this, stacked antenna configurations of TM11 and TM13 modes are thoroughly investigated and SLL suppression is demonstrated. Finally, to leverage further advantage of the linear superposition of modes, a single layer annular slot loaded antenna configuration is proposed. The proposed new configurations are based on higher order TM1m modes, which, for excitation, requires electrically large conducting discs. This property offers one more advantage at high frequencies, where antenna size becomes too small for the fundamental mode to fabricate and feed. The proposed electrically large antennas eliminate these problems, and become more practical to fabricate.

▼ Radiofrequency (RF) coils are a substantial part of Magnetic Resonance Imaging System. Microstrip transmission line (MTL) coils are widely used as they have a low coupling between array elements and negligible radiation loss. Matching and tuning capacitors are usually soldered to MTL coils in order to tune them to Larmor frequency and match them to 50Ω. Typically, these coils need to be adjusted according to different sample loadings (patients) in MRI. Availability and high cost of MR compatible variable or fixed capacitors for tuning and matching and the labour-intensive work encourage us to find an easy way to satisfy these requirements with low cost and less process steps. Here, we propose to use rapid prototyping (additive manufacturing), such as 3D printing, to overcome the existing problems and print MRI coils all at once including the matching/tuning capacitors. Additive Manufacturing is an emerging manufacturing technology that offers new prototyping and fabrication methods to RF world. Additive manufacturing technology could potentially grant reduction of fabrications steps for MTL coils. A typical desktop 3D printer is capable of printing only plastics, such as ABS and PLA. Moreover, there is no low cost 3D printer to provide metal and plastic printing in one machine. In this thesis, a low cost desktop 3D printer has been modified to add ink printing capability. In addition, the design procedure of MTL coils with parallel plate capacitors as matching and tuning capacitors is reported. 3D printing as a new technology is adopted to fabricate the MTL coils. The MTL coils with built-in parallel plate capacitors from plastic materials and two different conductive materials (copper tape and silver ink) are designed and fabricated for 4.7 T MRI systems. Moreover, the fabricated coil’s performance in terms of quality factor and SNR is investigated. Based on the results of this thesis, 3D printing technology provided faster prototyping process for MRI coils. It also allowed design iterations to increase the coil’s performance in MRI. 3D-printed parallel plate capacitors integrated with MTL coils eliminated the repetitive work of soldering, and mitigated the process for iterations during measurements. Thermoplastic material such as ABS and PLA showed comparable SNR and efficiency values to standard low loss foam, and therefore they can be used in MR applications. Ink-printed MTL coils showed lower performance compared to low loss foam, and that can be attributed to the ink conductivity.

Antenna is one of the most critical component for wireless communication systems. The antenna must also be adaptive to act as a directional device to optimize or accentuate the transmitted or received energy in some directions while suppressing it in others. A good design of the antenna can be very useful in improving the overall system performance. Microstrip antennas have many attractive features which has considerable attention for wireless communication applications. Researchers are engaged in removing this limitation and many techniques have been proposed for the design of wideband antennas for wireless communication systems. Methods for increasing the bandwidth of microstrip antenna are continuously getting upgraded. Undoubtedly the simplest microstrip antenna configuration is rectangular microstrip parch antenna. Hence this investigation deals with rectangular microstrip antenna. The prototype antenna 2 demonstrates that a broadband rectangular microstrip patch antenna with narrow slots and parasitic element. This antenna is excited by an L-probe fed. The bandwidth is improved by two parallel narrow slots on the main patch and parasitic patch. The design provides a simulated impedance bandwidth of 71.33% with gain of 8.6dbi. It has been observed that additional gap-coupled parasitic element yields considerably wider impedance bandwidth. This antenna configuration can be used in applications where wider impedance bandwidths are needed and variations in the radiation pattern are tolerated. The main patch is excited by proximity coupling. This antenna provides a dual frequency response with the simulated impedance bandwidth of 63.35% and 33.48% with a gain of 6 dBi. The design demonstrates that all the three antennas overcome the inherent narrow bandwidth of the conventional microstrip antenna. The main advantages of these antennas are their improved bandwidth with the acceptable performance of low return loss, good gain and radiation characteristics. newline newline newline

Planar antennas are paramount in today's world because they can be embedded easily into portable devices such as laptops, mobile phones, etc. Beam or the radiation with directivity is important beacause it gives a suitable range advantage than omnidirectionally radiating antennas with the same power. Steerability can provide the flexibility of the omnidirectional antenna and the benefit of a directional antenna; provided that multiplexing is possible. Reconfigurable antennas that can radiate multiple patterns at a single frequency or a single spectrum are necessary for modern telecommunication systems. The requirements for increased functionalities like direction finding, beam steering, radar, control and command, within a confined volume place a greater burden on today's transmitting and receiving systems. Reconfigurable antennas offer an exceptional solution to this complex engineering problem.

This thesis contains the design of two particular fixed frequency beam-steerable antennas. The antennas are cost effective from the industrial perspective, and reliable for long term maintenance free use. The first one is a fixed frequency active phased array antenna. The relevant chapter showcases the layouts and results for two 1 x 2 variants and one 2 x 2 variant. Initial development of accurate transmission line models gave the insight of developing a fixed frequency active phased array antenna. Initial chapters outline the transmission-line modelling of single tunable and reconfigurable rectangular microstrip antenna elements. Analytically obtained values reasonably agree with the results achieved from measurements and simultaions, for numerous designs based on multiple substrates. The active phased array antenna can steer its beam up to 25°.

The limitations of the phased array antennas led to the design of the second fixed frequency beam-steerable antenna. The second beanm-steerable relies on a switchable ground plane that can reflect or transmit electromagnetic waves. The second antenna has a steerable beam that radiates either in the broadside or endfire region. The antenna can cove up to 133° in the H-plane. Later chapters in this thesis discuss the transmission-line modelling of the reconfigurable surface with numerous examples, and its operation as a surface waveguide. The examples for the transmission-line model demonstrate reasonable agreement with simulation results for different substrate thickness and with or…

Chapter 1. Introduction – Chapter 2. Literature review – Chapter 3. Improved S/X DBDP-SA microstrip array – Chapter 4. L/S/X tri-band dual-polarized microstrip array – Chapter 5. L/C DBDP-SA sandwiched stacked-patch array – Chapter 6. Conclusion and future research.

Multi-band systems are becoming increasingly popular in both military and civil applications such as tactical radar systems and synthetic aperture radar (SAR) systems because their information capacity is significantly higher than single-band counterparts. As the interface between free space and an internal wave guide, a multi-band antenna plays an important role in such systems.

A multi-band dual-polarized (MBDP) antenna array can be realized by simply positioning several single-band antenna arrays side-by-side. However, this approach is not desirable because it significantly increases the aperture size and antenna weight. The MBDP shared aperture antenna arrays studied in this thesis can minimize the array size and weight by sharing the aperture of each band. Therefore, it is attractive for some compact systems like space-borne SAR antennas and vehicle based tactical radars.

In this thesis, several contributions are made to the knowledge in MBDP shared aperture arrays. They are listed below.

1) Performance improving methods are presented for dual-band dual-polarized shared aperture (DBDP-SA) array. The inter-polarization isolation of the array was improved and the lower-band bandwidth was enhanced for a given antenna thickness. A prototype S/XDBDP-SA microstrip array has been designed and fabricated to verify these methods. Fractional frequency ratio is also achieved in a prototype array by adopting an interleaved dual band embedding structure.

2) A multi-band dual-polarized shared aperture (MBDP-SA) array design method is proposed for SAR applications. To verify the feasibility of this method, an L/S/X tri-band dual-polarized shared aperture (TBDP-SA) array has been designed and fabricated. Good performance has been achieved in all three bands.

3) A novel sandwiched stacked-patch DBDP array is presented, with an aim to enhance the bandwidth in the lower band. Dual band embedding methods are also studied and compared in terms of their bandwidth performance. An L/C DBDP-SA sandwiched stacked patch array has been designed and fabricated to validate this new concept.

▼ This is a very exciting time to investigate microstrip (aka. patch or printed) antennas because the world of technology is ready to take a big step towards the Internet of Things (IOT). With IOT almost every device we are involved with will communicate with one another. The only reasonable medium for communication will be wireless communication. Wireless communication involves antennas and antenna design always involves topics like size, flexibility, power consumption, efficiency, cost and weight. Out of the myriad list of antennas present in today’s world, microstrip antennas are among the most promising when it comes to ease of fabrication and extremely low profiles. They can hide under circuit boards, they can be made super flexible and very light. It is a wise assumption that almost all IOT devices will employ a printed antenna. In this thesis design, simulation, optimization, fabrication and characterization of a rectangular patch antenna has been done. The designed antenna was compatible with the IEEE 802.11b protocol for Wi-Fi as it was resonating at 2.4 GHz and the other antenna parameters like bandwidth, gain and Half Power Beam Width (HPBW) were also suitable for the protocol. This antenna was then used to design a four element patch array antenna. The performance of the array antenna was then compared with respect to the initially designed single rectangular patch antenna. After characterizing the array antenna in an anechoic chamber it was found that the array antenna has a gain of 12.5 dB which is 5.21 dB higher than the simulated gain of the initially designed single element antenna. The array antenna has a frequency bandwidth of 70 MHz and an efficiency of 80%. Both single element antenna and the array antenna can be used as a radiating element for IEEE 802.11b protocol. However, out of fourteen channels defined under the protocol, the single element antenna can fully support only up to channel number eight and partially support channel number nine. The array can fully support up to channel number ten and partially support channel number eleven. Advisors/Committee Members: Stern, Harold (advisor), Stephan, Karl D.

With the recent progress and rapid increase in mobile terminals, the design of antennas for small mobile terminals is acquiring great importance. In view of this situation, several design concepts are already been addressed by the scientists and engineers. Compactness and efficiency are the major criteria for mobile terminal antennas. The challenging task of the microwave scientists and engineers is to device compact printed radiating systems having broadband behavior, together with good efficiency. Printed antenna technology has received popularity among antenna scientists after the introduction of microstrip antenna in 1970s. The successors in this kind such as printed monopoles and planar inverted F are also equally important. Scientists and Engineers are trying to explore this technology as a viable coast effective solution for forthcoming microwave revolution. The transmission line perspectives of antennas are very interesting. The concept behind any electromagnetic radiator is simple. Any electromagnetic system with a discontinuity is radiating electromagnetic energy. The size, shape and the orientation of the discontinuities controls the radiation characteristics of the system such as radiation pattern, gain, polarization etc. It can be either resonant or non resonant structure. Microstrip antennas are suitable for wireless applications due to their low cost, high gain and ease of fabrication. But the major disadvantage of micro strip antennas is their inherent narrow bandwidth. A lot of techniques are introduced by the researchers all over the world to enhance the bandwidth of micro strip patch antennas. The thesis addresses an attempt to enhance the bandwidth of micro strip patch antennas by incorporating impedance matching strip as a part of the micro strip patch antenna. The first part of the thesis deals with the broadband operation of the tilted square slot and polygonal slot loaded square micro strip patch antennas. The resonant mechanisms are clearly mentioned using the simulation and experimental studies. The bandwidth of the polygonal slotted broadband patch antenna is again enhanced by implementing an Lstrip feed mechanism. In the second major part of the thesis, a novel gain enhancement technique for single band and broadband square micro strip patch antennas is achieved by implementing offset stacked configurations.

Terahertz frequency (THz) band is coarsely defined as a portion of the electromagnetic spectrum which extends from 0.1 THz to 10 THz. Due to the unavailability of the powerful sources, detectors and other hardware, this regime of the spectrum has remained untouched by scientists and researchers for a long time and named as terahertz band gap . In the last two decades, the semi-conductor technology has grown exponentially and its effect on the research in this terahertz bandgap has also been noticed. With the sustaining progress in the terahertz research, various potential applications of this spectrum in the field of science and technology have been reported. newlineApart from the conventional applications, a new area of debate is the application of the terahertz band in the future wireless communication system. Due to the exponential growth in the population, the demand for the high-data rate communication systems is increasing. As per the latest survey, by 2015, the communication system has to enhance its bandwidth to cater the data rate upto 40-100 Gbps for the indoor and 100 Gbps for outdoor communication and it is a challenge to the scientific community. There are two possible ways in which the data rate can be enhanced. First, by increasing the bandwidth of the communication system but the system is inherited with the narrow bandwidth and in most of the cases the device bandwidth is only about 10% of its operating frequency. The next solution to this problem is to increase the operating frequency to such an extent that even with the narrow bandwidth, the communication system may fetch a high data-rate to target customers. Recently, to meet the high bandwidth requirement, 60 GHz and 90 GHz wireless systems have been developed but they are still insufficient to meet the future requirement. The next best solution to this problem is to move the operating frequency to the terahertz band which is sandwiched between microwave and far-infrared frequency band.

Les dispositifs électroniques modernes comportent souvent une ou plusieurs phases de veille, dans lesquelles elles attendent un ordre de réveil de la part d’un actionneur distant (une télécommande). Ces types de dispositifs ont tendance à être de plus en plus présents dans les habitations et dans les bâtiments tertiaires, en particulier dans le domaine de la domotique. Les phases de veille sont caractérisées par des niveaux de consommations très inférieures aux consommations en mode actif des dispositifs, mais les durées de veille sont généralement grandes devant les périodes actives. Ce fait, combiné à la multiplication des dispositifs, mène à des consommations annuelles qui peuvent dépasser 10 % de la facture d’électricité des ménages. Cette étude propose une nouvelle approche de réveil des dispositifs en veille. Au lieu d’avoir une écoute permanente en réception et d’envoyer une trame d’informations de réveil, le récepteur est complètement endormi et est réveillé à travers une impulsion d’énergie transmis par d’ondes électromagnétiques. Une fois que l’étage d’interprétation des données est alimenté, un envoi d’informations est effectué pour valider l’ordre de réveil. En vue des portées attendues pour le système et des contraintes normatives liées aux expositions des personnes aux champs électromagnétiques, une faible quantité d’énergie est disponible en réception pour le réveil du dispositif. Plusieurs topologies de circuits de rectification RF-DC (rectenna) en technologies microstrip sont étudiées à travers des simulations circuit et électromagnétiques. La topologie choisie a été optimisée pour fournir un bon niveau de tension DC pour des faibles niveaux de puissance RF incidente. Une adaptation entre le convertisseur et l’antenne de réception différente de 50 W a été utilisée. Tous ces résultats ont été validés expérimentalement. Au niveau du circuit de réception des données, plusieurs scénarios de fonctionnement ont été comparés. L’étage de démodulation utilise la rectenna comme détecteur à diodes, pour réduire au maximum la consommation et la complexité de mise en œuvre. Le système global a été testé et des gains substantiels sont constatés sur le bilan de consommation annuelle de plusieurs types des dispositifs, comparé à un fonctionnement classique. En parallèle, une architecture de récepteur d’énergie électromagnétique reconfigurable est proposée. Il offre l’avantage de pouvoir exploiter une large gamme de puissance incidente, ce qui n’est pas le cas des structures de rectennas classiques. Des rectennas en technologies discrètes et intégrées sont utilisées, connectées à une antenne commune à travers un switch d’antenne intégrée. Le système proposé est adaptatif et les résultats des tests montrent des améliorations notables de la quantité d’énergie collectée par rapport à des rectennas individuelles. Enfin, le phénomène de l’inversion de la tension dans une association déséquilibrée de rectennas est mis en évidence et des solutions sont proposées.

Modern electronic devices often include one or more phases…
