摘要

提出了一种基于吸收超表面的透明低雷达截面(RCS)天线。天线的接地和辐射贴片采用低方阻的氧化铟锡(ITO)导电膜，衬底采用透明玻璃材料，在透明辐射贴片周围设置有高方阻的透明吸收结构。仿真结果表明，该天线工作频率为8.88GHz。与原天线相比，RCS从8GHz显著降低到12GHz。最小降幅为10dB。在- 20°~ 20°入射角范围内，天线具有稳定的RCS消减效果。

Design of transparent and low RCS antenna based on absorbing metasurface

A transparent and low radar cross section (RCS) antenna based on absorbing metasurface is presented. The ground and radiation patch of the antenna are made of indium tin oxide (ITO) conductive film with low square resistance, the substrate is made of transparent glass material, and the transparent absorbing structures with high square resistance are arranged around the transparent radiation patch. The simulation results indicate that the proposed antenna works at 8.88GHz. It possesses remarkable RCS reduction from 8GHz to 12GHz compared with the original antenna. The minimum reduction is 10dB. Moreover, the antenna has stable RCS reduction effect in the range of −20° to 20° of incident angle.
