ABSTRACT

Circular phased array antennas with a quasi-omnidirectional pattern to generate transverse orbital angular momentum (OAM) waves with modes $\text{l = 0 }$ and $-1$ are designed at the frequency of 4 GHz. Proposed antennas consist of eight substrates integrated waveguide (SIW) H-plane horn elements and microstrip corporate feeding networks. Experimental results show that the mutual coupling between array antennas can be reduced by employing transverse OAM waves with different modes.

利用平面螺旋轨道角动量电磁波减少互耦合

摘要

具有准全向方向图的圆形相控阵天线，可生成具有模式的横向轨道角动量 (OAM) 波 $\text{l = 0 }$ 和 $-1$设计频率为 4 GHz。提议的天线由八个基板集成波导 (SIW) H 平面喇叭元件和微带公司馈电网络组成。实验结果表明，采用不同模式的横向OAM波可以降低阵列天线之间的相互耦合。
