摘要：

A design criterion for a small, compact, high-aperture-efficient antenna is proposed in this study. The proposed criterion is validated experimentally through fabricating and testing two prototypes for Ku-band and Ka-band applications. The proposed antenna design consists of a resonance slot perforated in an aluminium plate and surrounded by a cavity and two corrugations. The proposed Ku-band antenna has an aperture efficiency of 74.3% and a measured gain of 12.2dBi at 13GHz, while the Ka-band antenna resonates at 28.5GHz with a peak aperture efficiency of 78% and a gain of 12.9dBi. The gain of both antennas is dramatically boosted by the radiation from the cavity and corrugations, resulting in a significant enhancement in the aperture efficiency.
