Abstract
An antenna module includes a dielectric substrate having a multilayer structure, a radiating element, a feed wiring, a filter device, and a ground electrode. The dielectric substrate has a first main surface and a second main surface. The radiating element is formed on the first main surface of the dielectric substrate or in an inner layer than the first main surface. The feed wiring transmits a radio frequency signal to the radiating element. The filter device is arranged on the feed wiring. The ground electrode faces the radiating element and is arranged in a layer between the radiating element and the filter device. A recess is formed in the second main surface of the dielectric substrate. The filter device 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.
