An antenna device 100 is provided with: a plurality of antenna units 30A, 30B, which are disposed in a row, and which respectively have antennas 1A, 1B that generate reception signals by receiving electromagnetic waves from a satellite, and antenna drive units 3A, 3B that change the orientation directions, i.e., the directions which the antennas 1A, 1B face; a direction command value generation unit 5, which generates direction command values, i.e., command values to be given to the antenna drive units 3A, 3B, such that the direction in which the satellite is present and the orientation directions match each other; a phase difference calculation unit 4 that calculates a phase difference, which is a difference between the phases of the reception signals generated by the antennas 1A, 1B; and a signal synthesizing device 40 that synthesizes reception signals on the basis of the phase difference. |
