ABSTRACT:
The present invention provides a transparent antenna for an automobile. The antenna includes a glass substrate a first electroconductive antenna element positioned on a central portion of a major surface of said substrate, a second electroconductive antenna element positioned on the major surface of the substrate, spaced from the first element, and at least one electroconductive connector extending between the antenna elements and overlaying and electrically interconnected with a portion of both the first and second antenna elements. A portion of the connector extends beyond the periphery of the glass substrate to be connected to an external connector. The first element and preferably both elements are a transparent, electroconductive coating. In one particular embodiment of the invention, the first element is spaced from the peripheral edge of the substrate and the second element is positioned between the first element and the substrate edge. The antenna may be incorporated into a laminated vehicle windshield so that an additional glass ply is secured to the first glass substrate such that the first and second coating elements are positioned between the glass plies.
