Patent ID: 7880679

Claim:
A multiband antenna system for a window pane, comprising: a heating conductor field having lateral recesses; an antenna conductor structure for at least two reception ranges outside the heating conductor field, wherein the antenna conductor structure is situated substantially in the lateral recesses of the heating conductor field; and a coupling of the antenna conductor structure to the heating conductor field, wherein the coupling is effective for one of the at least two reception regions, wherein the coupling has a low-resistance at high-frequencies, and wherein the coupling is not galvanic; wherein the heating conductor field is made up of at least two connected segments, including a first segment and a second segment, that are disposed such that the heating conductor field essentially covers an entire wiper region of the window pane, and wherein a circuit trace width of the heating conductors of the second segment of the at least two connected segments is smaller than a circuit trace width of heating conductors of the first segment of the at least two connected segments, so as to provide an essentially uniform defrosting of the window pane.
