摘要

提出一种用于便携式终端的多输入多输出（MIMO）天线。手持终端天线的工作频带为5G（3.4–3.8 GHz）和WLAN（5.150–5.925 GHz）。5G和WLAN频段的天线单元交错放置，尽量保证同频单元间距离较远，以减少天线元件间的耦合。所有天线元件回波损耗均大于6 dB。所有元件间隔离度大于14 dB。高频天线辐射效率大于50%，低频天线辐射效率大于40%。所有元件远场增益大于2.2 dBi。

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.
