摘要

提出了一种用于超宽带应用的多输入多输出(MIMO)天线，该天线由两个混合型单极子组成。在所提出的天线中，使用一对以短柱端接的矩形带来实现UWB上≥20 dB的隔离。群延迟和传递函数响应的变化分别在1 ns和13 dB以内。3.1 ~ 10.6 GHz范围内的包络相关系数< 0.05，表明该天线适合UWB MIMO应用。

Mutual coupling reduction using shorting posts in UWB MIMO antennas

A multiple input multiple output (MIMO) antenna consisting of two hybrid shaped monopoles for UWB applications is presented. In the proposed antenna, a pair of rectangular strips terminated with shorting posts is used to achieve isolation ≥ 20 dB over UWB. The variations in group delay and transfer-function response are within 1 ns and 13 dB respectively. The envelope correlation coefficient < 0.05 over 3.1–10.6 GHz indicate that the proposed antenna is suitable for UWB MIMO applications.
