<P>PROBLEM TO BE SOLVED: To suppress a characteristic deterioration in an array antenna due to phase shift that temporarily occurs between delay calibration and phase amplitude calibration. Ž<P>SOLUTION: A radio communication device using the array antenna has the array antenna composed of a plurality of antennas, a calibration means for making delay amounts and phase amplitude changes of transmission paths including the respective antennas coincide with one another to uniform characteristics among the respective antennas for the array antenna, and a processing part for determining a phase rotation amount due to a change in a delay correction amount of the transmission paths of the respective antennas, which is determined by the calibration means to calculate a phase correction amount, and simultaneously performing delay correction and phase amplitude correction using the phase correction amount.
