Abstract

A broadband multimode orbital angular momentum (OAM) four-feed circular patch antenna at 6 GHz is proposed in this study. The OAM antenna exhibits 5.8-dBi maximum gain, has an impedance bandwidth of 25% over the frequency range 5.2-6.7 GHz with more than 10-dB return loss. Additionally, the OAM modes + 1, -1 and OAM modes +2, -2 can be generated from 5.2 to 6.5 GHz, whose mode purity is much better than the previous two-feed configuration.

一种宽带多oam模式高模式纯度四馈圆形贴片天线

提出了一种6ghz宽带多模轨道角动量(OAM)四馈圆形贴片天线。OAM天线的最大增益为5.8 dbi，在5.2-6.7 GHz频率范围内阻抗带宽为25%，回波损耗大于10 db。此外，在5.2 ~ 6.5 GHz范围内可以产生OAM模式+ 1、-1和OAM模式+2、-2，其模式纯度比以前的双馈配置要好得多。
