An antenna module includes a substrate, a ground electrode, a first subarray of patch antennas disposed on a first main side of the ground electrode. Feed circuitry is disposed on a second side of the ground electrode and connected to the first subarray via a feed line A signal line connects the feed circuit and an external connection terminal. When viewed in plan in a first direction normal to the substrate, the external connection terminal does not overlap the first subarray or the feed circuit. When viewed in plan in a second direction orthogonal to the first direction, at least a part of the signal line is between one or more of the plurality of patch antennas and the ground electrode. When viewed in plan in the first direction, the signal line does not overlap the first subarray.
