摘要

通过适当采用超表面阵列，提出了一种具有低散射特性的宽带圆极化贴片天线。通过将设计的超表面阵列布置在角截断贴片圆极化贴片天线周围，获得轴比带增强和增益改进的圆极化辐射。对于散射情况，在线极化入射下，通过反射波之间的相位抵消实现带内和带外雷达截面(RCS)的减小。

Low Scattering Wideband Circularly Polarized Patch Antenna Using Metasurface Array

Through proper adopting metasurface array, a wideband circularly polarized patch antenna with low scattering characteristic is presented. By arraying the designed metasurface array around the corner-truncated patch circularly polarized patch antenna, an axial-ratio band-enhanced and gain-improved circular polarization radiation is obtained. For scattering case, under linearly polarized incidence, in-band and out-of-band radar cross section (RCS) reduction is achieved by phase cancellation between reflected waves.
