Abstract
An adaptive array antenna having a plurality of array antennas including a plurality of antenna elements which are spaced at first intervals at which a large first correlation is exhibited, the array antennas being spaced at second intervals at which a second correlation is negligible, where a diversity of effects are produced, such as fading compensation, eliminating by interference waves coming from the same direction, and augmenting the gain by main beam tracking, providing one or more calibration signal coupling parts and multi-beam synthesizing circuit are so as to remove individual variations in calibration signals and to perform highly reliable calibration.
