PROBLEM TO BE SOLVED: To provide an array antenna system in which broken transmission/ reception modules and a distributor can be maintained and exchanged. SOLUTION: The system is provided with a distributor 3 for distributing and outputting high frequency signals from a transmitter, a plurality of transmission/reception modules 2 for phase-controlling individual output signals and outputting it, a plurality of antenna elements 1 for radiating transmission radio waves in an optional direction, and a connecting circuit 4 to which these elements 1, modules 2 and the distributor 3 are connected. A connection part 5 for connecting the elements 1 is provided on the front surface of this circuit 4, a connection part 8 for connecting the modules 2 and the distributor 3 is provided on the rear surface of the circuit 4. Further, a first transmission line 9 for connection with connection parts 5 and 6 and a second transmission line 10 for connection with the other connecting part 7 of the modules and the part 8 of the distributor are formed in the circuit 4.
