摘要：

An ultra-wideband and high gain Fabry-Perot cavity (FPC) antennas is designed using frequency selective surface (FSS) and parasitic microstrip patch. The 3-dB gain bandwidth of the proposed FPC antenna is 19.1% mainly benefits from the FSS with reflection phase increasing with frequency. Moreover, compared with the source antenna the peak gain of the FPC antenna is improved from 8 dBi to 14 dBi. Compared with the normal U-slot antenna the 10-dB impedance bandwidth of the one with three parasitic patches microstrip U-slot antenna is improved from 11.4% to 54.5%. To validate the feasibility of the proposed approach, an FPC antenna prototype has been designed. It consists of a U-slot parasitic microstrip patch antenna as the source, two complementary frequency selective surfaces (FSS) as the partially reflective surface (PRS). Therefore, this new approach can be an effective way to enhance the gain and impedance bandwidth without increasing the cavity profile or using multi-layer superstrate structures.
