Abstract:
The feed efficiency, a first approximation to the aperture efficiency of a paraboloid or a conventional Cassegrain antenna, is used to define uniquely a combinedE- andH-plane phase center of the feed pattern. A formula for numerical calculation of the combined phase center is presented, as well as theoretical results of the feed position tolerances and the efficiency loss due to differences in the principal plane phase patterns.
