CASSEGRAIN ANTENNA FOR HIGH GAIN

摘要

Provided is a high gain Cassegrain antenna. The antenna includes a feed unit (130) that radiates radio waves, a subreflector (120) that faces a radiation surface of the feed unit and reflects the radiated radio waves, and a main reflector (1 10) that has a plurality of hole scatterers (1 1 1 ) of different depths facing the subreflector (120) and reflecting again the radio waves reflected from the subreflector (120). Accordingly, it is possible to manufacture a high-gain broadband antenna at low costs.
