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&#x2212;1) fed antenna elements (to) which are coupled to the parasitic antenna elements (to) by electromagnetic fields, and (n&#x2212;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).

In the setting operation conducted by the handle,which is an operating section, an upper portion of the portion,&prime; of the slidable T-post,is pushed by the end portion of the cam,, and the slidable T-post,is moved. In accordance with the movement of the card,, the suction cup block,is elastically deformed, and the suction cup,is held by the body,by a holding force of the suction cup,. The body,is composed of a porous body, and air flows from the ventilation hole,into a space formed between the suction cup,and the body,, via the body,. The slidable T-post,is biased ahead by the return spring,. When the releasing operation is conducted by the handle,, the cam,is rotated, and the end portion of the cam,is separated from the end of the portion,&prime; to be pushed. After that, when the intensity of the holding force of the suction cup,to the body,is decreased lower than that of the spring force of the return spring,, the slidable T-post,is moved ahead, so that the card member,pushes up the movable contactor
