Abstract:
This antenna module (100) is provided with: a dielectric substrate (130) having a multi-layer structure; a ground electrode (GND) disposed in the dielectric substrate (130); a power feeding element (121) which faces the ground electrode (GND), is disposed on a different layer from the ground layer (GND), and has a planer shape; a power feeding wire (140) which delivers a high frequency signal to a power feeding point (SP1) of the power feeding element (121); and a stub (150). The stub (150) has an open end (OE1) and branches from the power feeding wire (140) at a branch point (BP1) in the power feeding wire (140). The stub (150) is disposed between the power feeding element (121) and the ground electrode (GND). When the dielectric substrate (130) is viewed in a plan view, the open end (OE1) overlaps the power feeding element (121).
