摘要：

This paper presents a wideband high-gain dual-circularly-polarized (CP) antenna with a simple configuration. Instead of improving the gain using the dual-CP element array, the Fabry-Perot resonator antenna concept is applied in this work. By designing a dual-linearly-polarized Fabry-Perot resonator antenna and a linear-to-circular polarization (LP-CP) metasurface polarizer separately and combining them, a wideband high-gain dual-CP antenna can be achieved. Structural simplicity and less design difficulty are advantages of the antenna design. Experimental results validate the design concept. It exhibits 3-dB axial-ratio bandwidths of over 12% for both LHCP and RHCP performance, a high polarization isolation of over 25 dB, and peak gains of 12.78 dBi and 12.89 dBi for LHCP and RHCP radiations respectively.
