PHASED ARRAY ANTENNA AND ITS PHASE CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide a phase array antenna capable of arranging the phase surfaces of signals emitted from respective panels as the entire antenna panel and highly efficiently transmitting power by adjusting the phase shift amounts of signals outputted from respective antenna elements, and its phase control method.

SOLUTION: On the basis of an arriving direction angle formed of the arriving direction of pilot signals and the antenna panel, distances between an antenna reference line orthogonal to the arriving direction of the pilot signals and the respective antenna elements is calculated. Corresponding to the respective calculated distances, the phase shift amount of microwaves to be emitted from the antenna element is decided.
