Abstract
The present disclosure reduces a loss of strength of a radio-frequency signal radiated from an antenna module covered with a housing. An antenna module () includes a dielectric substrate (), a driven element (), and a ground conductor (). The dielectric substrate () has a multilayer structure. The driven element () is disposed in or on the dielectric substrate (). The ground conductor () is disposed between the driven element () and a mounting surface () on which a power supply circuit is mountable. The power supply circuit supplies the driven element () with radio-frequency power. The dielectric substrate has at least one groove (). The at least one groove () is separate from the driven element () when the antenna module () is viewed in plan. The at least one groove () extends toward the ground conductor () from a layer on which the driven element () is disposed.
