Abstract
An apparatus and method for mitigating polarization mismatch in reflector antenna systems. A feed unit is configured to determine a polarization mismatch between a first polarization associated with a first wave and a second polarization associated with a reflector unit. The feed unit pre-distorts the first wave to achieve a compensated polarization for reducing and/or eliminating a polarization mismatch. The pre-distorted first wave having the compensated polarization is used to illuminate the reflector unit. A re-radiated wave is reflected by the reflector unit. Furthermore, the level of the re-radiated wave is increased as a result of the pre-distortion.
