Antenna module and communication device provided with the same

An antenna module comprising:

• a dielectric substrate having a multilayer structure;
• a feed circuit element in the dielectric substrate and supplied with a radio frequency power;
• a ground electrode in the dielectric substrate;
• a parasitic circuit element in a layer that is between the feed circuit element and the ground electrode;
• and
• a first feed wire penetrating through the parasitic circuit element and supplying the radio frequency power to the feed circuit element,
• wherein when the antenna module is viewed in a plan view from a normal direction of the dielectric substrate, at least part of the feed circuit element overlaps the parasitic circuit element,
• wherein, in the plan view, a first position at which the first feed wire is connected to the feed circuit element is different than a second position at which the first feed wire reaches, from a side of the ground electrode, the layer in which the parasitic circuit element is located, and
• wherein the first feed wire is offset in the layer in which the parasitic circuit element is located, or the first feed wire is offset in the layer in which the parasitic circuit element is located.
