PROBLEM TO BE SOLVED: To provide a calibration device capable of suitably supporting property variation about a reference antenna system at the time of calibration. SOLUTION: The calibration device comprises a reference antenna system B used for calibration provided separately from antenna systems A1-An for calibration, and a calibration processing means (baseband portion and arithmetic circuit 40) for measuring the property of reference antenna system B at the time of calibration and performing calibration for the antenna systems A1-An using the measurement result as a reference point.
