An antenna device is mounted on a vehicle and performs vehicle-to-vehicle and road-to-vehicle communications using a plurality of communicators including antennas. The antenna device includes one or more hardware processors coupled to one or more memories, and configured to function as, communication control units, a vehicle state detection unit, and operation control units. Communication control units are each provided in one of the plurality of communicators and control transmission/reception operations of the antennas connected to the communicators. A vehicle state detection unit detects a state of the vehicle and operation states of the communication control units. Operation control units are each provided in one of the plurality of communicators and control the operation states of the communication control units according to the state of the vehicle detected by the vehicle state detection unit and the operation states of the communication control units, for each of the plurality of communicators.
