摘要

提出了一种基于超表面的频率可重构天线。天线，即超表面天线，由贴片天线构成，贴片天线上覆盖有大量周期性排列的椭圆单元格的超表面。频率重构可以通过机械旋转超表面来实现。测量结果与仿真结果一致，表明旋转90度可以使谐振频率从4.52GHz变化到5.31GHz。天线增益可达6.8dBi。超表面天线具有外形小、增益高、无有源干扰等优点。

Design of frequency reconfigurable antenna based on metasurface

A novel frequency reconfigurable antenna based on metasurface is proposed in this paper. The antenna, namely metasurface antenna, is made by a patch antenna covered with a metasurface in which numerous elliptical unit cells arranged periodically. The frequency reconfiguration can be realized by rotating the metasurface mechanically. Measured results, consistent with simulation ones, show ninety degree rotation can make resonant frequency changing from 4.52GHz to 5.31GHz. Antenna gain can reach 6.8dBi. The metasurface antenna has the advantages of low profile, high gain and no active jamming.
