Abstract
A window antenna is provided for receiving electromagnetic radio waves from a motor vehicle. The vehicle has a metallic structure that forms an aperture with a window glass disposed within. The window glass has an upper region and a substantially horizontal top edge that interfaces with the metallic structure. The antenna is formed from an electrically conducting material affixed to the window glass. The antenna includes a horizontally elongate principal element that is substantially parallel to and spaced from the upper edge portion of the window. The principal element electrically connects to a connecting element which extends downwardly therefrom. The connecting element electrically connects to an auxiliary element that is spaced below the principal element by an amount sufficient that no significant coupling is formed therewith.
