Abstract
Provided is a vehicle antenna system that is able to efficiently receive circularly polarized signals from the zenith direction. A vehicle antenna system () is provided with window glass () for a vehicle () and an antenna element () that is able to receive signals of a predetermined frequency band. The antenna element () is provided on a first principal plane of a dielectric substrate (), and includes a radiating conductor () that is able to receive circularly polarized signals of a first frequency, and a grounding conductor () positioned opposite the radiating conductor () via the dielectric substrate (). The normal direction of the first principal plane is less than or equal to 45° relative to the vertical direction, and the radiating conductor () is positioned away from the inner surface of the window glass () via the dielectric layer () in the direction of the vehicle interior.
