Abstract
A new method aimed to design wideband microstrip antennas with low radar cross section (RCS) is proposed in this paper. The reflection phase inverse points and the 0° phase reflection points of the AMC unit cells can be designed to obtain 180°(± 30°) effective phase difference over broadband frequency range. The antenna is fabricated on a chessboard configuration which is structured with two AMC unit cells. Both simulated and measured results show that the proposed antenna possesses more than 7 dB RCS reduction with 69.2% relative bandwidth for both polarizations, covering the working band of the original antenna. The maximum reduction is 31.4 dB. Meanwhile, the radiation properties of the antenna are almost not changed.
