Radiation characteristics of a waveguide-excited short backfire-fed parabolic reflector operating in Q-band
Abstract
The letter presents measured results at 31-38 GHz of the radiation characteristics of a 0.252m diameter parabolic dish fed at the prime focus by a short backfire antenna. The feed consists of an experimentally optimized design of a short backfire antenna, having a conical main reflector of 15 deg slant angle. The measured radiation patterns of the reflector system generally agree quite well with the prediction based on aperture field integration.
