1. Lin, Bo-Wei. Wideband MIMO Antennas for the 5G Smartphone.

Degree: Master, Electrical Engineering, 2018, NSYSU

The frequency band of 3300~5000 MHz considered in the study has recently been identified by many countries to be potentially available in the fifth-generation (5G) mobile communication below 6000 MHz. It is therefore necessary for the 5G MIMO antennas to cover the wide band of 3300~5000 MHz. There are two wide band 5G MIMO antennas presented in this thesis. The first design is a hybrid inverted-F/loop antenna, which can generate a 0.25λ inverted-F antenna resonant mode and a 0.25λ loop antenna resonant mode. The two modes are combined into a wide band to cover 3300~5000 MHz. In addition, with a wide band obtained, the antenna requires a small planar size of 5 à 12 mm2. For such four 5G antennas, its total length along the side-edge frame of the smartphone is 75 mm only. Furthermore, in order to operate in heterogeneous networks, such as the mobile network and the wireless local area network (WLAN), 5G/WLAN MIMO antennas for the second design are presented. The 5G/WLAN MIMO antennas are based on the first design. By adding an additional loop antenna resonant path to the first design, it can cover 2400~2500, 3300~5000, and 5100~5900 MHz. The 5G/WLAN MIMO antenna has a small planar size of 5 à 25 mm2 and is also disposed along the side-edge frame of the smartphone. Good envelope correlation coefficients and isolation of the two 5G/WLAN MIMO antennas is obtained by placing the antennasâ radiators which contribute different resonant modes to face each other. In this case, two 5G/WLAN MIMO antennas can be spaced by 5 mm only to achieve acceptable decoupling. Finally, the six-antenna structure composed of the above two designs is presented to provide six 5G bands and two WLAN bands. From the obtained experimental results, the proposed six-antenna structure is promising for the 6 à 6 5G MIMO and 2 à 2 WLAN MIMO operations.

2. Chian, De-Ming. Eight 3.5/5.8-GHz Dual-Band MIMO Antennas for the 5G Smartphone.

Degree: Master, Electrical Engineering, 2017, NSYSU

For the Massive MIMO (Multi-input Multi-output) operation in the fifth-generation (5G) communications, eight MIMO antennas embedded in the smartphone for 8 x 8 MIMO operation are presented. To achieve seamless wireless connection, the eight antennas are designed to cover the 3.5 GHz band for mobile communication and the 5.8 GHz band for wireless local area network operation. The eight dual-band MIMO antennas for the 3.5/5.8-GHz operation are formed by four two-antenna building blocks, which are disposed along two long side edges of the system ground plane in the smartphone. The ground clearance of the two-antenna building block is 1 mm only, which is promising for practical application in the smartphone with a large display panel. In addition, the two-antenna building block has a compact planar structure of size 7 Ã 17.5 mm2. The antenna efficiency of the eight antennas is respectively larger than 45% and 60% in the 3.5 and 5.8 GHz bands, and the ECC is less than 0.2 between any two antennas thereof. Moreover, the total length of two two-antenna building block is only 50 mm, which is about 0.6 wavelength at 3.5 GHz. To analyze the upper bound on the data throughput, the Shannon channel capacity and its physical concept are studied. The data throughput has been found to reach over 2.7 Gbps in the experimental testing for the smartphone with the proposed eight 3.5/5.8-GHz MIMO antennas in an indoor environment. The obtained results indicate that the proposed MIMO antennas are promising for applications in the fifth-generation communications. Advisors/Committee Members: Wen-Shyang Chen (chair), Tsung-Wen Chiu (chair), Kin-Lu Wong (committee member).
