Study of Offset Parabolic Cylindrical Reflector Antenna for Spatial Power Combining

Chu Qing-xin

Abstract

A study of an offset parabolic cylindrical reflector antenna for spatial power combining is presented.The calculation based on aperture integral is agreed well with the measurement.The best dimensions of the feeding horn,the best feeding orientation and the best edge level of the reflector are calculated.The relationship between the antenna gain factor and the dimensions of the parabolic cylindrical reflector is analyzed.The gain factor of the antenna with an E_plane array feed is higher than that of the antenna with an H_plane array feed.Results of this paper are useful for the design of spatial power combining antenna.
