A communications apparatus an antenna module include a first substrate on which a first radiation electrode and a first ground electrode are disposed; a second substrate on which a second radiation electrode and a second ground electrode are disposed; a third substrate on which a third ground electrode is disposed; and a first connection member having a flat plate shape and connected between the first substrate and the second substrate, a fourth ground electrode being disposed on the first connection member. A radio frequency signal is transmitted to the first radiation electrode through the first connection member, and a main surface of the first connection member is in contact with a main surface of the third substrate.

Antenna module and communication apparatus equipped with the same

An antenna module includes a first substrate, a second substrate, a connection member connected between the first substrate and the second substrate, and an FEM disposed on the connection member. A radiating element is disposed on the first substrate. An RFIC for supplying a radio frequency signal to the radiating element is disposed on the second substrate. The connection member transmits radio frequency signals between the RFIC and the radiating element. The FEM amplifies radio frequency signals transmitted between the RFIC and the radiating element. The FEM is disposed at a position between a connecting point with the first substrate and a connecting point with the second substrate on the connection member.
