文摘The characteristics of the phase centers of electromagnetic horns having nearlysymmetric pattern are presented analytically.It is proved that the phase center on the φ=45°plane coincides with the average phase center,and if a single plane phase center is used to definethe horn phase center approximately,the φ=45° plane phase center will be the best choice.
