Abstract

The broadband circularly polarized Fabry-Perot resonator (FPR) antenna is presented, which consists of a partially reflective surface (PRS) as cover, a metal-dielectric surface as ground plate and an embedded L-probe coupled rectangular patch as primary radiator. The partially reflective surface covered plate composed of appropriate frequency selective surface (FSS) structure with rectangular patch elements printed on the bottom surface of superstrate. By adjusting the aspect ratio of rectangular patch and the rectangular FSS element, the bandwidth of the circularly polarized (CP) operation can be enhanced. For the proposed antenna, a common frequency bandwidth of 7.7 % for S₁₁ ≤ -10dB and gain-drop ≤ 3 dB and axial ratio ≤ 3 dB is obtained.
