Provided is an antenna device that can favorably maintain a reception level even in an environment where vibrations are generated in the antenna device. An antenna unit is connected to a housing part (210) so as to be capable of relative oscillation. Disposed on the housing part (210) are acceleration sensors (231-234) for detecting acceleration produced in the azimuth direction and the elevation direction. Linear actuators (251A, 252A) are disposed between the housing unit (210) and the antenna unit (220) such that the angle of the antenna unit (220) relative to the housing unit (210) can be adjusted. A fluctuation amount calculation unit (312) calculates the amount of fluctuation in the elevation direction and the azimuth direction on the basis of the detected acceleration detected by the acceleration sensors (231-234). A correction amount calculation unit (313) calculates the amount of correction for cancelling the amount of fluctuation calculated by the fluctuation amount calculation unit (312). On the basis of this amount of correction, the linear actuators (251A, 252A) are driven. |
