摘      要：We propose a dual-module multiple-input multiple-output(MIMO)antenna for portable *** operating bands of the handheld terminal antenna are 5G(3.4–3.8 GHz)and WLAN(5.150–5.925 GHz).Antenna elements of 5G and WLAN are spaced to reduce coupling between antenna elements in the same *** return loss of all antenna elements is larger than 6 *** isolation between all elements is larger than 14 *** radiation efficiency of the high-frequency antenna is greater than 50%,and the radiation efficiency of the low-frequency antenna is greater than 40%.The far-field gain of all elements is greater than 2.2 dBi.
