ABSTRACT:
An antenna system improves the radiation pattern of an antenna on a vehicle. An antenna includes a ground plane and receives RF signals. The antenna is mounted on a vehicle surface in close proximity to a vehicle window. A conductive structure is located on the vehicle window adjacent to the vehicle surface and communicates with the antenna. The conductive structure extends the ground plane of the antenna.
