Abstract:In this paper, a wideband Fabry-Perot (FP) resonator antenna is designed based on single-layer frequency selective surface (FSS) structure. The antenna adopts a single-layer complementary circular FSS structure as the partially reflecting surface (PRS) of Fabry-Perot resonator antenna to improve the gain. The wideband slot-coupled patch antenna is used as the source. The proposed FSS maintains a positive slope reflection phase gradient in the band of 10.3-16.0 GHz, which satisfies the realization conditions of the wideband Fabry-Perot resonator antenna. The measured results show that the 10-dB impedance matching bandwidth of the proposed Fabry-Perot resonator antenna covers 11.99-15.54 GHz (25.8%), the maximum gain is 13.16 dBi at 14.2 GHz, and the 3-dB gain bandwidth is 26.1%. The measurement results verify the feasibility of the design method. © ACES
