PROBLEM TO BE SOLVED: To suppress a side lobe level in an elevation angle direction in directional characteristics of an antenna in a vertical plane. SOLUTION: An array antenna system which has M antenna elements arrayed in a prescribed direction is characterized in that a tilt angleθ2 of N antenna elements at one end among the M antenna elements and a tilt angleθ3 of N antenna elements at the other end are different from a tilt angleθ1 of (M-2N) antenna elements disposed between the one end and the other end.
