A side-frame dual-band multi-input multi-output (MIMO) antenna system for fifth-generation (5G) mobile communication in smartphone applications is presented, operating in 3.5 GHz band (3400-3600 MHz) and 5 GHz band (4800-5000 MHz). The proposed four-element antenna array is placed at four corners of the circuit board and printed on the side edge frame. The height of the structure is only 4.1 mm, which is compatible for ultra-thin full screen smartphones. According to the verification of HFSS and CST, ideal impedance matching bandwidths (superior to 10dB) and excellent isolations (superior to 18 dB) are obtained over the 3.5 GHz band and 5 GHz band, with peak gain of 6.18 dB and 4.9 dB, respectively.

A quad-port antenna array operating in 3.5 GHz band (3.4–3.6 GHz) and 5 GHz band (4.8–5 GHz) for fifth-generation (5G) smartphone applications is presented in this paper. The single antenna element consists of an L-shaped strip, a parasitic rectangle strip, and a modified Z-shaped strip. To reserve space for 2G/3G/4G antennas, the quad-port antenna array is printed along the two long frames of the smartphone. The evolution design and the analysis of the optimal parameters of a single antenna element are derived to investigate the principle of the antenna. The prototype of the presented antenna is tested and the measured results agree well with the simulation. The measured total efficiency is better than 70% and the isolation is larger than 16.5 dB.
