In telecommunications and radar, a Cassegrain antenna is a parabolic antenna in which the feed antenna is mounted at or behind the surface of the concave main parabolic reflector dish and is aimed at a smaller convex secondary reflector suspended in front of the primary reflector. The beam of radio waves from the feed illuminates the secondary reflector, which reflects it back to the main reflector dish, which reflects it forward again to form the desired beam.

WebThe simplest reflector antenna consists of two components: a reflecting surface and a much smaller feed antennaat the reflector’s focal point. Constructions that are more complex involve a secondary reflector (a subreflector) at the focal point, which is illuminated by a primary feed.
