    Abstract
  • An artificial magnetic conductor (AMC) chessboard reflector is designed which shows low backscattered radar cross sections (RCS) in a broad frequency band in this paper. Designed by the phase cancellation principle, a conventional chessboard low RCS metasurface can be formed by polarization-dependent mushroom-shaped AMCs. Two new features are added to this design based on the conventional chessboard metasurface. Firstly, the long edge of the metallic patch on the AMC element is concave to obtain a broader bandwidth. Then, the width of the patch in each AMC block is tapered in one direction to further extend the operating bandwidth for RCS reduction. The backscattered RCS of the tapered AMC reflector is numerically investigated and compared with a non-tapered one. It is found that by introducing the above features, an RCS reduction greater than 10.dB can be obtained by the reflectors with relative bandwidth of 46% in the X-band.
