5G MIMO Antenna System for Mobile Terminals

Abstract

A wideband 4-antenna array system that can cover the 5G new radio band N77 (3.3-4.2GHz) is proposed for the 5G operation in mobile terminals. The antenna system is based on the self-isolated antenna element and thus quite high isolation (better than -17.9 dB) within the entire band is achieved for the proposed antenna system. The envelope correlation coefficient and the channel capacity of the MIMO antenna system are also studied. The results such as antenna S-parameter, current distribution, radiation pattern and efficiency are also presented.
