摘要：
Fabry-Perot cavity (FPC) antennas are well known for their high-gain feature using simple cavity resonance, which only a single feeding element can feed. However, their aperture efficiency is limited despite the antenna size increase due to leaking waves through lateral openings. To solve this problem, we propose a new method to improve aperture efficiency by blocking the openings with optimum feeding locations. Consequently, our antenna shows about 64 % aperture efficiency in a bore sight direction. Our idea is verified by simulation and experiment.
