摘要
A reflect array-feeding array (RA-FA) antenna is disclosed. The RA-FA antenna comprising: a reflect array base comprising a plurality of reflecting elements with a phase shift distribution to reflect an incident beam to generate a reflected beam having a narrower beamwidth in an elevation plane and a same beamwidth in an azimuth plane, and a feeding array comprising a phased antenna array with a beam-steering ability to direct the incident beam at the reflecting elements. The reflecting elements may be configured in a pattern with rows and columns and reflecting elements along rows have a same phase shift, and reflecting elements along columns have phase shifts to narrow the incident beam to form the reflected beam narrower in the elevation plane.
