Abstract
An antenna device includes a main reflector (), a sub-reflector () including sub-reflector panels and having a reflecting surface facing a reflecting surface of the main reflector, and a primary emitter () to receive a radio wave reflected by the sub-reflector (). Each of sub-reflector panel drive mechanisms coupled to the sub-reflector panels is finely driven. A phase calculator () calculates a relative phase of an element electric-field vector corresponding to each of the sub-reflector panels based on a change in received electric-field strength of the radio wave received by the primary emitter () during driving of the sub-reflector panel drive mechanisms, and determines positions of the sub-reflector panels at which a phase distribution on an aperture surface of the main reflector () is minimized.
