PROBLEM TO BE SOLVED: To provide an array antenna reception device where antenna elements are linearly arranged in the respective sides (sectors) of a polygon, directional patterns having gains in the direction of a desired signal are independently formed for respective sectors, the desired signal is received, interference by another user and a multi-path is suppressed and weighting/synthesis are executed among the sectors. SOLUTION: The device constituted of an antenna part 1 formed of M-pieces of antenna elements 211-2KM which are linearly arranged in the respective sides (sectors) of a K angular form, adaptive reception parts 31-3K forming directional patterns having gains in the direction of a desired signal against M-pieces of antenna reception signals multiplexed by the signals of plural users for the respective sectors, receiving the desired signal and suppressing an interference signal and a demodulation signal synthesis part 4 weighting/synthesizing K-pieces of demodulation signals for the respective sectors and outputting the user demodulation signals.
