Vehicle antenna system

A vehicle antenna system comprising:

• a window glass for a vehicle;
• and
• an antenna element that is able to receive signals in a predetermined frequency band, the antenna element including:
• a first radiating conductor that is provided on a first principal plane of a first dielectric substrate and that is able to receive circularly polarized signals of a first frequency,
• a second radiating conductor positioned opposite the first radiating conductor via the first dielectric substrate, the second radiating conductor is able to receive circularly polarized waves of a second frequency that is lower than the first frequency, and
• a grounding conductor positioned opposite the first radiating conductor and the second radiating conductor via a second dielectric substrate,
• wherein the normal direction of the first principal plane is less than or equal to 45° relative to the vertical direction, and
• wherein the first radiating conductor is positioned away from the inner surface of the window glass via a dielectric layer in the direction of the vehicle interior.
