چکیده
In this paper, a wideband eight-element multiple-input multiple-output (MIMO) antenna array for 5G smartphone applications is presented. Each composed of dual-arm tortuous monopole radiating element with double-stub tuner and an open slot on the ground plane. Tuning stub microstrip lines are utilized to improve impedance matching. The operating bandwidth single from 3200 6000 MHz three resonant frequencies. covers new radio (NR) bands (n77/n78/n79) WLAN-5GHz band. isolation proposed MIMO above 10 dB in entire band without any elements. Furthermore, was manufactured measured. measured results validate that has wide 6-dB 3.2 6 GHz isolations all more than dB. total efficiency ranges 38% 83%. show can support smartphones.
