Abstract
A reflector antenna device includes: an auxiliary reflectorthat receives an electric wave radiated from an opening portion by a primary radiatorand reflects the electric wave; and a main reflectorthat receives the electric wave that is reflected by the auxiliary reflectorand radiates the electric wave to a space. In the reflector antenna device, the configurations of the auxiliary reflectorand the main reflectorare designed such that an electric power in an area of the main reflectorwhere the auxiliary reflectoris projected on the main reflectorin parallel with the radiating direction of the electric wave due to the main reflectoris equalor lower than a predetermined first threshold value, and a radiation pattern of the antenna which is determined by the area of the main reflectorother than the area has a desired characteristic.
