Abstract
An array antenna device AAD including: a plurality of element antennas EAs; a transmission/reception module TRM, which is to be connected to one of the EAs, and includes a transmission circuit TC, a reception circuit RC, and a transmission/reception switch; a transmission/reception controller controlling by controlling an amplitude and phase of a signal passing through each TC and RC, and by switching transmission/reception; a distributor distributing a signal from a signal transmitter to each TC to transmit a distributed signal from the each TC; a combiner combining a signal from the each RC; and a receiver receiving the combined signal. A detection signal, which contains a detected amplitude and phase of the signal received by the receiver, is corrected with a piece of interconnection amplitude-phase information about the EAs to obtain a calibration value in calibration of each TRM, and calibration is conducted with the calibration value.
