<P>PROBLEM TO BE SOLVED: To provide an array antenna apparatus which prevents antenna characteristics from deteriorating due to an environmental change and is easily made compact. Ž<P>SOLUTION: The array antenna apparatus includes: a plurality of antenna elements 22-1, 22-2, 22-3, ..., 22-n; a sensor for environmental change detection 31 for detecting environmental information at a place where the plurality of antenna elements 22-1, 22-2, 22-3, ..., 22-n are provided; a database 41 for selecting to output correction values of respective coordinates of the plurality of antenna elements 22-1, 22-2, 22-3, ..., 22-n on the basis of the detected environmental information; an antenna element coordinates calculation circuit 51 for calculating the respective coordinates of the plurality of antenna elements 22-1, 22-2, 22-3, ..., 22-n on the basis of the output correction values; and an antenna controller 61 for calculating to output phase codes for controlling phase amounts to the plurality of respective antenna elements 22-1, 22-2, 22-3, ..., 22-n on the basis of the respective calculated coordinates of the plurality of antenna elements 22-1, 22-2, 22-3, ..., 22-n.
