Abstract: The paper describes a kind of circular polarization feed, which is used for shaped beam antenna. The special problems in designing multibeam antenna, which constructs shaped beam, are discussed.Theory, experiment and the comparison between them show that the cross septum feed is suitable for solving this kind of problems. The effects of various feeds on antenna gain in coverage area are compared so that the advantage of the cross septum feed is confirmed further.

Key words: Circularly polarized antenna, Shaped beam antenna, Satellite antenna
