Abstract

A system for reducing antenna spillover in a satellite communications system is disclosed. The system may include an apparatus comprising an antenna terminal, which in turn may include a sub-reflector and a main reflector. The main reflector may include at least one of an extension, a shroud, and a serrated edge. The extension may be a full rim extension or a partial extension. The shroud may be a full shroud or a partial shroud. The serrated edge may include a straight serration or a curved serration, the serrated edge also having various dimensions and profiles. In some examples, the sub-reflector and the main reflector of the antenna terminal may be provided and configured to reduce antenna spillover in accordance with antenna performance and interference restrictions set forth by one or more governing bodies.
