PURPOSE: A compact nonaxisymmetric double-reflector antenna is provided to include a feed for forming a plane wave front, thereby achieving a low profile and increased aperture efficiency. CONSTITUTION: A main reflector and a sub reflector have two planes that are opposite to each other at a cross point where a longitudinal axis is positioned. Each of the main reflector and the sub reflector is formed with nonaxisymmetric curvilinear surfaces. A double-reflector antenna is positioned between the main reflector and the sub reflector and includes at least one feed to form a plane wave front. |
