Abstract

PURPOSE:To improve the frequency characteristic of the aperture efficiency of an antenna by setting the level of electric field intensity it an aperture circumference higher than the minimum level of the electric field intensity at the middle part of an aperture radius, in geometric optical aperture distribution, used for shaping a reflector surface. CONSTITUTION:In case of an axially symmetric Cassegrain antenna, a double reflector antenna is constituted of a primary emitter 1, an auxiliary reflector 2 and a main reflector 3. The geometric optical aperture distribution, used for shaping the reflector, is set so that the level of the electric field intensity at the aperture circumference of the main reflector 3 is higher than the electric field intensity at the middle part of the aperture radius. Thus, the double reflector antenna, which has the good aperture efficiency in plural frequency bands, is obtained.
