An antenna module (1) includes an antenna array (100) that includes a plurality of radiation conductors (11) arranged at regular intervals in or on a dielectric substrate (14) and an RFIC (20) that is provided in or on the dielectric substrate (14) and that performs signal processing on a transmission signal transmitted by the antenna array (100) or a reception signal received by the patch antenna array (100). Each of the plurality of radiation conductors (11) has a transmission feeding point from which the transmission signal is transmitted to the RFIC (20) and a reception feeding point at which the reception signal is received from the RFIC (20).
