ABSTRACT:
A reflector antenna device includes: an auxiliary reflector1that receives an electric wave radiated from an opening portion by a primary radiator3and reflects the electric wave; and a main reflector2that receives the electric wave that is reflected by the auxiliary reflector1and radiates the electric wave to a space. In the reflector antenna device, the configurations of the auxiliary reflector1and the main reflector2are designed such that an electric power in an area of the main reflector2where the auxiliary reflector1is projected on the main reflector2in parallel with the radiating direction of the electric wave due to the main reflector2is equal1or lower than a predetermined first threshold value, and a radiation pattern of the antenna which is determined by the area of the main reflector2other than the area has a desired characteristic.
