Popis: In this paper, a simultaneous improvement of radiating and scattering performance for a patch antenna is realized. For achieving the wideband low-scattering property, a broadband AMC structure with orthogonally slot-embedding is proposed and analyzed, which is arranged around the antenna with another square ring unit in a chessboard configuration for phase cancellation. Meanwhile, a gain increment is also achieved due to the coupling between the radiation patch and the broadband AMC structure. Measured results indicate that at least a 10 dB RCS reduction is obtained from 11 GHz to 17.8 GHz. Additionally, the gain of the antenna has also been increased for more than 2 dB between 12 GHz and 13 GHz.
