本文介绍了一种平面宽带棋盘结构的设计、制造和特性，以减少目标的雷达横截面（RCS）。棋盘状的结构是由两个人工磁导体（AMC）细胞组合而成的。通过正确选择两种AMC结构的相位斜率与频率的关系，克服了AMC结构固有的带宽限制。在超过40%的频宽范围内获得了180相位差，RCS降低幅度大于10 dB。研究了入射角对工作带宽的影响。仿真结果与实测结果吻合较好。
This paper presents the design, fabrication, and characterization of a planar broadband chessboard structure to reduce the radar cross-section (RCS) of an object. The chessboard-like configuration is formed by combining two artificial magnetic conductor (AMC) cells. The bandwidth limitations intrinsic to AMC structures are overcome in this work by properly selecting the phase slope versus frequency of both AMC structures. A 180 phase difference has been obtained over more than 40% frequency bandwidth with a RCS reduction larger than 10 dB. The influence of the incidence angle in the working bandwidth has been performed. A good agreement between simulations and measurements is achieved.
