A Compact 5G-MIMO Antenna with Reduced Mutual Coupling

Abstract

In this paper, a compact 24 rectangular MIMO array antenna is proposed for the 3.45 GHz operating lationofrequency with relative low mutual coupling and high is is 116 between its elements. The Overall size of the structure ng theimm 74 mm. The isolation is enhanced up to 17 dB by us ine andlspiral defected ground structure (DGS), neutralization o thetresistive loading of the antenna elements. In compared is reference paper, the area of the proposed array antenna reduced 24% and the isolation between its elements is tableiincreased 2–5 dB. The proposed structure seems to be su. for 5G smartphone applications
