A CONTOURED BEAM ANTENNA DESIGN FOR CHINESE COMMUNICATION SATELLITE ON Ku BAND

Abstract

Abstract: A design method of contoured beam antenna covering all Chi- nese territory is described for Chinese communication satellite on Ku band. By considering available technique and technology level of China,three feasible conceptions are presented;with the three conceptions,how to select geometry dimensions of the offset parabolic reflector,how to arrange feed locations of multiple beam antenna and how to optimize amplitude and phase excitation coefficients of the feeds are discussed progressively;at last, contour coverage patterns of the three conceptions are shown,and the comparison of advantage and disadvantage among the three conceptions are made.

Key words: Communication satellite, Antenna system, Beam, Optimum design, China
