1. An antenna wireless device comprising:
a plurality of antenna elements on a substrate;
feed ports each associated with a corresponding one of the plurality of antenna elements;
one or more detection ports each associated with a corresponding at least one or all of the plurality of antenna elements;
transceiver circuits each connected to a corresponding one of the feed ports; and
one or more reference transceiver circuits each connected to a corresponding one or a corresponding plurality of detection ports of the one or more detection ports,
wherein
for each antenna element of the plurality of antenna elements,
a corresponding transceiver circuit of the transceiver circuits
subjects a first signal to transmission processing including digital to analog conversion and up-conversion to generate a second signal, and
feeds the second signal to a corresponding feed port of the feed ports,
the corresponding feed port being connected to the corresponding transceiver circuit,
the second signal fed to the corresponding feed port is output to a corresponding reference transceiver circuit of the one or more reference transceiver circuits through a corresponding detection port of the one or more detection ports,
the corresponding reference transceiver circuit being connected to the corresponding detection port,
the corresponding detection port being associated with the antenna element with which the corresponding feed port is associated,
the corresponding reference transceiver circuit
subjects the second signal to processing including analog to digital conversion and down-conversion to generate a third signal,
detects a first amplitude and phase deviation based on the first signal and the third signal, and
outputs the first amplitude and phase deviation to the corresponding transceiver circuit, and
the corresponding transceiver circuit adjusts a phase and an amplitude of a transmission signal based on the first amplitude and phase deviation.
