First Claim
1. An antenna glazing for automobiles, comprising:
- an electrically conducting cladding extending over a surface of the glazing, an edge zone around an outer periphery of the glazing being free of the cladding, said cladding serving as antenna element; and
a coupling electrode including external connections and a wire, said electrode being capacitively coupled to the cladding through an insulating layer,wherein the wire includes two ends electrically connected with the external connections, the two ends located at the edge zone, and the wire is arranged such that one end of the two ends is located at the edge zone, is conducted over the surface covered by the cladding, and is returned to the edge zone by forming at least one loop.

Abstract
An antenna glazing for automobiles, including an electrically conducting cladding extending surface-wise over the surface of the glazing up to a zone of the free edge of the cladding, serving as an antenna element, and a coupling electrode furnished with external connections, coupled in the capacitive regime to the electrically conducting cladding with interposition of an insulating layer. The coupling electrode is composed at least of one thin wire, which starts from the zone at the edge of the glazing, is conducted over the surface covered by the cladding, and is returned to the zone of the edge with at least one fold, so that the two ends of the wire are situated in the zone of the edge of the glazing.
