ANTENNA MODULE, AND COMMUNICATION DEVICE EQUIPPED WITH SAME

WIPO Patent Application WO/2023/248550

A1

Provided is an antenna module (100) in which: hybrid couplers (150A, 150B) each have input terminals (IN1, IN2) and output terminals (OUT1, OUT2); distributors (140A, 140B) each distribute a high-frequency signal from an RFIC in two directions; the distributor (140A) distributes a first signal from the RFIC to the input terminals (IN1) of the hybrid couplers; the distributor (140B) distributes a second signal from the RFIC to the input terminals (IN2) of the hybrid couplers; the output terminals (OUT1, OUT2) of the hybrid coupler (150A) are connected respectively to radiation elements (121D, 122D); the output terminals (OUY1, OUT2) of the hybrid coupler (150B) are connected to radiation elements (121E, 122E), respectively; and in the hybrid couplers, the phase difference between the high-frequency signals supplied to the input terminals (IN1, IN2) is set to 90°.
