Abstract
To provide an adaptive array antenna capable of increasing resolution of a variable beam direction of the antenna without increasing a calculation amount in arithmetic processing unit for optimally controlling a variable phase shifter. A parasitic element-equipped adaptive array antenna () includes n (n is an integer equal to or greater than 2) parasitic antenna elements (to), (n−1) fed antenna elements (to) which are coupled to the parasitic antenna elements (to) by electromagnetic fields, and (n−1) variable phase shifters (to) which change the phases of radio frequency signals to be supplied to the respective fed antenna elements (to). Each of the fed antenna elements (to) is arranged astride at least two of the parasitic antenna elements (to).
