1. An antenna module comprising:
a base member;
an antenna comprising a radiating element in or on the base member;
a first feed line and a second feed line that are connected to the radiating element; and
a control circuit that is connected to the radiating element via the first feed line and the second feed line,
wherein the control circuit comprises:
a signal processing circuit that is connected to the antenna via the first feed line and the second feed line, and
an antenna inspection circuit configured to check an electrical conductivity of an electrical conduction path, the electrical conduction path connecting the first feed line, the radiating element, and the second feed line to each other,
wherein the base member has a first surface and a second surface, the second surface being opposite the first surface,
wherein the antenna is on the first surface, and
wherein the control circuit is on the second surface of the base member.
