摘要

本文提出了一种适用于圆柱平台的低rcs共形天线。为了提高孔径利用率，采用圆形辐射贴片。扇形超表面单元围绕天线布置，形成双环布局。基于相位抵消原理，实现了带内和带外RCS的降低。仿真结果表明，该天线实现了宽带RCS从5.0 GHz降至9.5 GHz的目标。同时保持了良好的辐射性能。

Broadband RCS reduction of Microstrip Antenna Using Conformal Metasurface

In this paper, a low-RCS conformal antenna for cylindrical platform application is proposed. To improve the aperture utilization rate, circular radiation patch is adopted. Fan-shaped metasurface cells are arranged around the antenna to form a dual-ring layout. Based on phase cancellation principle, both in-band and out-of-band RCS reductions are achieved. Simulated results show that the proposed antenna achieves broadband RCS reduction from 5.0 GHz to 9.5 GHz. Meanwhile, the well-behaved radiation performance is kept.
