Abstract
An antenna device includes a dielectric substrate having a first main surface and a second main surface, a feedpoint provided at a predetermined position of the dielectric substrate, a first radiating element provided on the first main surface and extending from the feedpoint in a predetermined direction, an interlayer connection conductor connected to the first radiating element, a second radiating element provided on the second main surface and extending from the interlayer connection conductor in the predetermined direction, and a third radiating element extending from the feedpoint in the predetermined direction on a path different from a path of the first radiating element. The first radiating element has a U-shaped part that turns away from the feedpoint in a predetermined direction and then turns back and approaches the feedpoint. The third radiating element has a meander-shaped part that meanders by repeatedly approaching and going away from the first radiating element in the plan view.
