Abstract
We propose a dual-module multiple-input multiple-output (MIMO) antenna for portable terminals. The 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 module. The return loss of all antenna elements is larger than 6 dB. The isolation between all elements is larger than 14 dB. The 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.
