US Patent 11063340 Antenna module and communication device

The present disclosure includes: an RFIC (110A) and an RFIC (110B) that are configured to respectively supply radio-frequency power to a first antenna group and a second antenna group; and a divider that divides a reference frequency signal input thereto and outputs the resulting first radio-frequency signals to the RFIC (110A) and the RFIC (110B). The divider is a Wilkinson-type first divider that is formed of a circuit system of a second impedance that is lower than a first impedance that is an impedance of signal transmission system into which the divider is inserted.
