Abstract
The antenna device includes an antenna unit () mounted so that its direction is adjustable, a motor-driven unit () that changes a direction of the antenna unit (), a camera () fixed so that its direction relative to the antenna unit () does not change, and a direction adjustment control unit () that supplies a drive signal to the motor-driven unit () and adjusts the direction of the antenna unit (). The direction adjustment control unit () performs feedback control to return the direction of the antenna unit () back to an initial direction based on an image taken by the camera (). It is thereby possible to maintain the communication quality even when a mechanical vibration occurs in a structure on which an antenna device is mounted.
