Abstract

Asymptotic theory based on geometrical optics and physical optics is developed for 3D array-fed reflector antenna with an offset parabolic reflector. Relationships between parameters of the antenna structure and its performances are presented. Procedures of a feed array design and a cluster design are described. Radiation performances are simulated and discussed. Quality of the antenna with electrical beam steering is considered in terms of aperture efficiency and element use efficiency. Quality of the antenna with a contoured beam or multiple beams is proposed to describe in terms of coverage efficiency.
