摘要

本文提出了一种用于可穿戴设备应用的双频2×2 MIMO天线，以支持中国3.3-3.6 GHz和4.5-5 GHz的5G无线电频率分配。单天线单元由单极模式和折叠环路模式组成，单馈电覆盖这两个频段。两个相同的天线位于智能手表大小的PCB (40×40mm2)的上下两侧，用于演示MIMO性能。xFDTD仿真结果表明，该MIMO天线在两个频段均能实现85%以上的效率、17db以上的隔离度和0.02的相关系数。

High performance MIMO antenna for 5G wearable devices

In this paper, a dual-band 2×2 MIMO antenna for wearable device applications is presented to support the 5G radio frequency allocations at 3.3–3.6 and 4.5–5 GHz in China. The single antenna unit is composed of a monopole mode and a folded loop mode with a single feed to cover these two bands. Two identical antennas positioned at top and bottom sides of a smart watch sized PCB (40×40mm2) are used to demonstrate the MIMO performance. The simulation results from xFDTD show that these MIMO antennas can achieve over 85 % efficiency, more than 17 dB isolation and 0.02 correlation coefficient at both bands.
