Abstract
A window assembly for a vehicle has a transparent layer including a metal compound such that the transparent layer is electrically conductive. The transparent layer defines an area covering the window assembly. An outer region which is electrically non-conductive surrounds the area. The window assembly includes an antenna element including wire or transparent coating which overlaps the transparent layer and overlaps the outer region. The antenna element is configured to receive linearly or circularly polarized radio frequency (RF) signals. A feeding element is coupled to the antenna element for energizing the antenna element. The antenna element is capacitively coupled to the transparent layer. The transparent layer operates as a parasitic or active antenna element with respect to the antenna element.
