The circular waveguide antenna feed with multiple coaxial cups is analyzed using the method of moments. The radiation properties of this type of prime focus feed are examined with particular emphasis on the level of cross-polarized radiation. It is demonstrated that by optimizing the feed dimensions the cross-polarization can be maintained below - 27 dB over a 20% bandwidth for a feed with a single coaxial cup. By examining the effects of various numbers of modes used to approximate the aperture fields it is concluded that quite accurate results can be obtained by including only the TE11 and TM11 modes in each aperture region. |
