摘要
摘要:该文设计了一种基于超表面(MS)的低雷达散射截面(RCS)宽频贴片阵列天线。该天线由工作在不同频段的两种开缝贴片天线组成2×4的八元阵，以此实现天线小型化并扩展其带宽，根据相位相消原理，将两种人工磁导体(AMC)以棋盘布阵的方式组成超表面加载到天线阵周围，使其具有低RCS特性。实测和仿真结果表明：加载超表面后，天线工作带宽由5.7~6.2 GHz扩展为5.6~6.6 GHz，相对带宽增大1倍，辐射特性基本保持不变；当平面波垂直入射时，天线单站RCS减缩效果明显，其中，X极化波下3 dB减缩带宽为5.3~7.0 GHz，最大减缩量达31 dB，Y极化波下3 dB减缩带宽为5.8~6.9 GHz。

Abstract:A wideband patch antenna array with low Radar Cross Section (RCS) based on metasurface is proposed. The 2×4 antenna array is composed of two kinds of slotted patch antennas working at different frequency band, realizing the miniaturization and bandwidth broadening of the antenna array. Then, based on the phase cancellation principle, low RCS performance is realized owing to the metasurface consisting of two Artificial Magnetic Conductor (AMC) structures in chessboard configuration. Simulated and measured results show that the working frequency band is expanded from 5.7~6.2 GHz to 5.6~6.6 GHz and radiation performance remains well with metasurface added to. Meanwhile the antenna monostatic RCS is reduced significantly. 3 dB RCS reduction is achieved over the range of 5.3 GHz to 7.0 GHz and the peak reduction is up to 31 dB under X polarization. While the 3 dB RCS reduction range is 5.8~6.9 GHz under Y polarization.
