Abstract

The multivariable optimization technique for the shaped feed system of dual-reflector antennas with the given circularly symmetric main reflector is described. The optimization criterion is the gaining of the maximum overall aperture efficiency η_a. Parameters for the optimum search are the mutual layout of the antenna elements, features of output energy distribution at the aperture and the subreflector profile. On the basis of the analysis of the dual-shaped reflector antennas the technique of the optimum feed system search was developed for different shapes of the given main reflector. The program application of the algorithms for the dual-shaped antenna synthesis and algorithms of the optimization is realized on the C++
