Design and Analysis of Mobile Phone Antenna System with Integration of LTE 4G, Sub-6G and Millimeter Wave 5G Technologies

In this paper, a mobile phone MIMO antenna system with combinations of LTE, sub-6G and millimeter wave 5G is proposed and analyzed. With advanced tunable, decoupling and beam-steering technologies, the results showed that it is possible to design 4×4 LTE, 8×8 sub-6G and 4×4 millimeter wave 5G antenna systems with desired performance for future's 5G mobile applications.
