摘要：

The design of two high-gain Fabry-Perot antennas with wideband low monostatic radar cross section (RCS) is presented in this paper. First, a phase gradient metasurface (PGM) without lossy layer is used to realize in-band RCS reduction and high aperture efficiency, simultaneously. The simulated results show that its peak gain is 19.2 dBi, and a high aperture efficiency of 58.6% is achieved. By utilizing the PGM structure, the monostatic RCS is reduced from 7 to 11 GHz, and the in-band co-polarization RCS is reduced by 13.1 dB. After that, a PGM with metamaterial absorber is designed to broaden the bandwidth of RCS reduction. A prototype antenna is fabricated and measured. The peak gain of 17.9 dBi is obtained, and the monostatic RCS is reduced in a wider frequency band of 7-15 GHz.
