REFLECTOR ANTENNA DEVICE

摘要

A reflector antenna device is configured to include a main reflector 1 that has a rectangular aperture shape 2, and a primary radiator 3 that radiates a beam having a rectangular shape similar to the aperture shape 2 of the main reflector 1 onto the main reflector 1. As the primary radiator 3, a multimode horn antenna, an active phased array antenna, or the like can be used. As a result, the degree of freedom of reflector shaping can be improved without causing reduction in efficiency.
