Abstract:
1. An antenna device comprising: a conductive body including a first surface and a second surface that are parallel to one another, and a third surface connecting the first and second surfaces, where the third surface includes a portion that is perpendicular to the first and second surfaces; an antenna coil disposed adjacent the first surface of the conductive body and defining a coil aperture portion with a coil axis extending therethrough, the coil axis being an imaginary line about which the antenna coil is wound that extends in a direction that intersects the first surface of the conductive body; and a magnetic material core passing through the coil aperture portion of the antenna coil, wherein a center of the coil aperture portion of the antenna coil is positioned offset from a center of the first surface of the conductive body in a direction towards the third surface of the conductive body, and a first end in a magnetic path direction of the magnetic material core extends at least along the third surface of the conductive body, and a second end on a side opposite to the first end of the magnetic material core is positioned along the first surface of the conductive body.
