Abstract
A phased array antenna (1) includes: a plurality of antenna elements (11a to 11d); a plurality of signal paths (R11 and R12) that are connected to each of the antenna elements; a storage unit (M) configured to store a set values of at least one of amplitudes or phases of a signal passed through at least one predefined reference path among the plurality of signal paths with regard to at least one of the antenna elements, and an amplitude and phase control unit (22 or 26) configured to control at least one of the amplitude or the phase of the signal passed through the reference path connected to the antenna element by using the set value stored in the storage unit, and configured to control amplitude or phase of signal passed through the signal path other than the reference path.
