Chip antenna and antenna device
First Claim
1. A chip antenna comprising a substrate comprising at least one material selected from a dielectric material and a magnetic material, at least one conductor formed at least one of in an interior portion of the substrate and on a surface of said substrate, at least one feeding terminal provided on the surface of said substrate and connected to a first end of said conductor for applying a voltage to said conductor, and at least one capacitor-forming conductor provided in the interior of said substrate and connected to a second end of said conductor, the substrate comprising a plurality of layers stacked on top of each other, the stacked layers establishing a direction of stacking the stacked layers normal to surfaces of the stacked layers, the conductor disposed spirally with respect to the substrate such that the conductor has a spiral axis extending perpendicular to the direction normal to the surfaces of the stacked layers.

Abstract
A chip antenna comprising a substrate comprising at least one material selected from a dielectric material and a magnetic material, at least one conductor formed at least one of in the interior of the substrate and on the surface of the substrate, at least one feeding terminal provided on the surface of the substrate and connected to an end of the conductor for applying a voltage to the conductor, and at least one capacitor-forming conductor provided at least one of in the interior of the substrate and on the surface of the substrate and connected to the other end of the conductor. An antenna device comprising an antenna main body and a mounting board for mounting the antenna main body is also disclosed. The antenna main body may have the same configuration as the above-described chip antenna.
