1. Huang, Chang-ying. Hybrid Inverted-F/Half-Loop Antenna for the LTE Metal-Framed/Metal-Casing Smartphone.

Degree: Master, Electrical Engineering, 2016, NSYSU

The hybrid inverted-F/half-loop antennas for the metal-framed/metal-casing smartphone are provided. The first design uses metal strips printed on the inner surface of the short-edge frame of the metal-framed smartphone as the antennaâs radiator. By connecting a feed network to the on-frame metal strips, an inverted-F antenna resonant mode and a half-loop antenna resonant mode can be generated. With a low profile of 3 mm, the antenna can cover the LTE band of 824~960/1710~2690 MHz and the GPS band 1575 MHz with the aid of the matching circuit in the feed network. The second design uses metal frame section of the metal-casing smartphone as the antennaâs radiator. By using an elevated feed circuit board connected to the metal frame section, both a half-loop antenna resonant mode and an inverted-F antenna resonant mode can also be obtained. The feed circuit board with the feed network disposed thereon does not occupy the planar space on the metal casing. In this case, with a narrow metal clearance of 2 mm, the antenna can provide two wide bands of 824~960/1710~2690 MHz for the LTE operation. Details of the two proposed antennas are presented, and there operating principle and experimental results are presented and discussed. Advisors/Committee Members: Ting-Wei Kang (chair), Kin-Lu Wong (committee member), Liang-che Chou (chair).

2. Tsai, Chih-Yu. MIMO Antennas for the Multi-Gbps 5G Smartphone and MIMO Channel Capacity Testing.

Degree: PhD, Electrical Engineering, 2017, NSYSU

The High-Dimensional (HD) MIMO operation with at least eight MIMO streams is a very promising technology for applications in the fifth-generation (5G) mobile communication terminals. HD MIMO can provide a much higher spectral efficiency, thereby increasing the data throughput in practical communications. However, it has been a great challenge for antenna designers to dispose as many as MIMO antennas with low envelope correlation coefficients (ECCs) in the very limited space of the smartphone. In this thesis, promising eight and twelve MIMO antennas for the 5G smartphone are presented. The MIMO antennas are formed by using decoupled two-antenna building blocks. The building block has a small planar size of 7 x 10 mm2 for operating at 3.5-GHz band (3400~3600 MHz) and can be printed on the inner surface of the side-edge frame of the smartphone. Decreased coupling between the two antennas can be obtained without the need of an external decoupling structure. The operating principle and antenna performance of the two decoupled antennas in the building block are presented in this study. To demonstrate Multi-Gbps data throughput for the smartphone, four or six two-antenna building blocks are used to implement eight or twelve MIMO antennas. By using the MIMO testbed developed at NSYSU, the measured channel capacity of about 35 bps/Hz with 20-dB signal-to-noise ratio (SNR) is obtained with eight antennas applied in an 8 x 8 MIMO system. In the case of twelve antennas applied in a 12 x 8 MIMO system, a 3.8-Gbps throughput (about 38 bps/Hz spectral efficiency) with a 100-MHz bandwidth and 256-QAM modulation has also been achieved. To further analyze the channel capacity and throughput of the twelve-antenna smartphone applied in a 12 x 8 MIMO system, the userâs hand effects, various indoor/outdoor scenarios, and the ECC effects are tested. The design concept of the decoupled two-antenna building block has also been applied in achieving 3.5/5.8-GHz dual-band operation for mobile and wireless local area networks. The dual-band eight MIMO antennas have been experimentally studied. The obtained MIMO performance is presented and discussed.
