A mathematical model of the circularly polarized feed is developed in this paper.The approach,for the Jacobi-Bessel series expansion of the physical optics radiation integral studied by R.Mittraet al.is extended to the case of circular polarizition.A computation method for the circularly polar-ized contoured beam of the offset reflector antennas is analysed.Representative numerical resultis given for effective isotropic radiated power contour-plot of the western zone coverage of Chineseterritory by the 7-element array illumination.

Mittra et al. Extended to the case of circular polarizition. A computation method for the circularly polar-ized contoured beam of the offset reflector antennas is analyzed.
