Abstract
A antenna device, which includes a first dielectric substrate having a patch conductor disposed thereon; a second dielectric substrate having a grounding conductor disposed on a confronting substrate surface confronting the patch conductor; and a conductor for electromagnetic coupling, extending from the confronting substrate surface of the second dielectric substrate toward the first dielectric substrate, is provided. The antenna device is small and is capable of being mounted to a windowpane for a vehicle since the conductor for electromagnetic coupling is not connected to the grounding conductor with respect to a direct current and since the conductor for electromagnetic coupling and the patch conductor are electromagnetically coupled each other.
