Claim 15:
16. An antenna module comprising:
a dielectric substrate of a multilayer structure having a first main surface and a second main surface;
a radiating element formed on the first main surface or in an inner layer of the dielectric substrate;
a feed wiring that conveys a radio frequency signal to the radiating element;
a filter arranged on a signal path of the feed wiring;
a first ground electrode that faces the radiating element and is arranged in a layer between the radiating element and the filter;
a second ground electrode formed on the second main surface of the dielectric substrate or in another inner of the dielectric substrate; and
an electronic component, wherein
a recess that is offset from the second main surface toward the first main surface is formed in the second ground electrode,
the electronic component is arranged in the recess, and
the filter is arranged at a position that does not overlap with the recess when viewed in a plan view from a normal direction of the dielectric substrate.
