PROBLEM TO BE SOLVED: To provide a time-division multiplex array antenna device, capable of suppressing power consumption required for operation.SOLUTION: A time-division multiplex array antenna device 1 includes a reception signal intensity detector circuit 21 for measuring the reception signal intensity of a reception radio wave at a subsequent stage to a switch circuit 7 (switch 8). A switch speed control unit 23 sets a switch speed of the switch 8 to a low speed when monitoring, that is, in a state of waiting for a radio wave, so as to suppress power consumption required for operating the time-division multiplex array antenna device 1. When checking radio wave reception by reception signal intensity at monitoring, the switch speed control unit 23 switches the switch speed of the switch 8 to a high speed. By this, the time-division multiplex array antenna device 1 sets an antenna 2 to be a time-division multiplex array antenna, to perform radio wave reception reading operation. |
