Abstract
An antenna device has a substrate having a first surface and a second surface on the opposite side of the first surface, a first-surface-side conductive layer formed on the first surface of the substrate, a second-surface-side conductive layer formed on the second surface of the substrate, and through hole conductors connecting the first-surface-side conductive layer and the second-surface-side conductive layer. The first-surface-side conductive layer and the second-surface-side conductive layer are formed such that the first-surface-side conductive layer and the second-surface-side conductive layer are connected via the through hole conductors in a crank form from the first surface to second surface of the substrate.
