摘要
提出一种基于极化旋转超表面的天线RCS减缩方法。首先设计一种宽带极化旋转超表面单元,该单元具有工作频带宽、结构简单、性能好的特点;并由该单元基于棋盘形组阵构成棋盘形低RCS编码表面,将其应用于微带天线。结果表明,棋盘形低RCS编码表面应用于微带天线,在保证天线辐射性能的同时,能在宽频带内实现RCS减缩。
An antenna RCS reduction method is presented based on polarization conversion meta-surface(PCM).A polarization conversion meta-surface unit cell is proposed,which is charac-terized by wideband,simple structure and good performance.Low RCS coding surface is con-structed by the proposed PCM unit on the chessboard arrangement and it is applied to the mi-crostrip antenna.The results show that the radiation performance of the antenna could be en-sured by the chessboard low RCS coding surface and the RCS could be reduced in the wideband at the same time,too.
