Abstract
An antenna wireless device includes: antenna elements; feed ports respectively corresponding to the antenna elements; one or more detection ports each corresponding to some or all of the plurality of antenna elements; transceiver circuits respectively connected to feed ports; and one or more reference transceiver circuits each connected to a corresponding one or more of the one or more detection ports. For each antenna element, the transceiver circuit processes a first signal to generate a second signal, the second signal fed to the feed port is output to the reference transceiver circuit through the detection port, the reference transceiver circuit processes the second signal to generate a third signal, and detects an amplitude and phase deviation based on the first signal and the third signal, and the transceiver circuit adjusts a phase and an amplitude of a transmission signal based on the amplitude and phase deviation.
