摘要

毫米波圆极化天线具有减少极化失配和抑制多径干扰的特点，在恶劣环境下具有较好的稳定性，是提高通信系统性能的重要器件，相关的天线罩也发挥着越来越重要的作用。在这项工作中，我们提出了一种多层超表面，它可以将左手圆极化电磁波转换成右手圆极化波。仿真结果表明，该超表面在30 ~ 40 GHz±60°斜入射范围内，轴比$< 2$，插入损耗$< 2\mathbf{dB}$。

Millimeter Wave Band Left Hand Circular Polarization to Right Hand Circular Polarization Convertor Based on Multilayer Meta-surface

Millimeter wave circularly polarized antenna has the characteristics of reducing polarization mismatch and suppressing multipath interference, and has better stability in harsh environment, which is an important device to improve the performance of communication system, and the related radome also plays an increasingly important role. In this work, we present a multilayer metasurface, which can convert left hand circularly polarized electromagnetic waves into right hand circularly polarized waves. Simulation shows that such metasurface exhibits axle ratio $< 2$ and insertion loss $< 2\mathbf{dB}$ within ± 60° oblique angle incidence in the 30 - 40 GHz.
