摘要

提出了一种适用于Sub - 6ghz 5G应用的宽带圆极化多输入多输出(MIMO)天线。MIMO天线设计在FR4基板上，每个打印单极天线连接到同轴馈线。为了提高天线的增益，在天线下面放置了一个反射器。在3.4 ~ 4.9 GHz范围内，轴比为3db的10db回波损耗带宽为36.14%，传输系数小于-20 dB。

Wideband Circularly Polarized MIMO Antenna for Sub 6 GHz 5G Application

A broadband circularly polarized multiple-input multiple-output (MIMO) antenna for Sub 6 GHz 5G application is presented. The MIMO antenna has been designed on FR4 substrate and each printed monopole antenna is connected to a coaxial feed. To enhance antenna gain, a reflector is placed below the antenna. The bandwidth of 10 dB return loss with a 3 dB axial ratio is 36.14% from 3.4 to 4.9 GHz meanwhile transmission coefficients are less than -20 dB.
