摘要

提出了一种ka波段高阶模双馈轨道角动量贴片天线。圆极化OAM贴片天线的阻抗带宽为23.7%，回波损耗大于10db。在26.5 GHz至33 GHz范围内，产生了携带$l=\pm 1$ OAM模式的涡旋光束，模式纯度超过85%。此外，通过加载低轮廓透镜，可以将最大增益从6.7 dBic提高到15.7 dBic，光束发散角从37°收敛到6°。

A High-Order-Mode OAM Patch Antenna with High Gain and Low Divergence

A high-order-mode two-feed orbital angular momentum (OAM) patch antenna at Ka-band is proposed in this paper. The circularly polarized OAM patch antenna has an impedance bandwidth of 23.7% with more than 10-dB return loss. A vortex beam carrying $l=\pm 1$ OAM mode is generated with a mode purity over 85% from 26.5 GHz to 33 GHz. Additionally, by loading a low-profile lens, the maximum gain can be improved from 6.7 dBic to 15.7 dBic, and the beam divergence angle converges from 37° to 6°.
