  • Publication number: 20210005965
    Abstract: An active phased array antenna (APAA) device includes antenna elements, active circuits, switches, and a control circuit. The antenna elements transmit and receive radio waves. The active circuits are connected to the antenna elements and start an operation upon supply of power distributed from a power supply circuit and transmit and receive signals via the antenna elements to which the active circuits are connected. The switches are connected to the active circuits, and start, upon being closed, supply of power to the active circuits to which the switches are connected, and stop, upon being opened, the supply of power to the active circuits to which the switches are connected. The control circuit transmits to the switches switching signals to turn the switches on and off to control starting and stopping of the supply of power to the active circuits. The control circuit sets timing differences in execution timings of executing the start of the stop of supply of power to the active circuits.
