Abstract
Antenna feed chains and methods are disclosed. An antenna feed chain, include a feed horn having a first cross-polarization performance over a solid angle of interest and a frequency band of interest and a polarizer having a second cross-polarization performance over the solid angle of interest and the frequency band of interest. The polarizer is coupled to the feed horn. The first cross-polarization performance of the feed horn compensates for the second cross-polarization performance of the polarizer over the solid angle of interest and the frequency band of interest.
