Zusammenfassung:	An array antenna system, and a calibration method and apparatus thereof are provided. The calibration method includes measuring a signal loop including mutual coupling between antennas included in an array antenna, calculating a ratio of a reception (RX) signal received by each antenna to an RX signal received by a reference antenna of the array antenna based on a result of the measuring, and performing calibration of the array antenna based on the ratio.
