ABSTRACT:
The present invention provides a reflector antenna which has dual polarization with low cross polarization within the main lobe and side lobes of the radiation pattern. The antenna includes a dish-shaped main reflector with a center located, self-supporting tubular feed element and a sub-reflector mounted on the free end of the tube and located at the focal area of the main reflector. The tube and sub-reflector are separated by a space which can be open or filled with a dielectric material. The diameter of the sub-reflector is greater than the tube. The surface of the sub-reflector facing the main reflector includes one or more concentric circular corrugations which can be filled with a dielectric material.
