Abstract (en)
[origin: DE10010226A1] Provision of a vehicle window-mounted antenna capable of covering a wide range of radio- and television-reception frequencies, without resorting to additional accessory fittings, or to expensive filtering of the heating current supply for rear-window mounted units, the vehicle window has a thin electrically conductive and light-transparent, yet poorly heat-conductive layer fixed to the window glass, the movable window pane (1) being covered with the defined, conductive area (4) of a defined, conductive layer and having an antenna connection point (8) provided in the free-field (11) formed with window closed, between the sealing strip (13) in the lower edge of the window aperture and the window control device (14), and connected to the defined conductive area (4) for low-loss HF reception.

Die Erfindung betrifft eine Antenne auf dem Fenster eines Kraftfahrzeugs mit einer, an dem Fensterglas befestigten, dünnen, elektrisch leitfähigen und für Licht transparenten jedoch wärmetransmissionsmindernden Schicht. Das Fenster ist gebildet durch die in den Unterteil (18) einer Fahrzeugtüre (17) versenkbare und über eine Fensterhebeeinrichtung (14) bewegliche Fensterscheibe (1), welche mit der begrenzt leitenden Fläche (4) aus der begrenzt leitfähigen Schicht bedeckt ist. In dem bei geschlossenem Fenster bestehenden Freifeld (11) zwischen der horizontalen Dichtungsleiste (13) am unteren Rand der Fensteröffnung und der Fensterhebeeinrichtung (14) ist eine Antennenanschlußstelle (8) gebildet, welche hochfrequent verlustarm an die begrenzt leitfähige Fläche (4) angeschlossen ist. <IMAGE>
