Abstract
(DE)
Die Erfindung betrifft eine Fahrzeugscheibe, aufweisend ein erstes Substrat (GS1) und mindestens eine erste elektrisch leitende Schicht (LS1), wobei die Fahrzeugscheibe an zumindest einem Abschnitt am Rand der Fahrzeugscheibe einen Schwarzdruck aufweist, wobei die erste elektrisch leitende Schicht (LS1) zumindest abschnittsweise hinter dem Schwarzdruck angeordnet ist, wobei in dem Abschnitt der erste elektrisch leitenden Schicht (LS1), der hinter dem Schwarzdruck angeordnet ist eine erste Antennenstruktur (ANT1) und eine zweite Antennenstruktur (ANT2) angeordnet sind, wobei die erste Antennenstruktur (ANT1) und die zweite Antennenstruktur (ANT2) jeweils Vorzugsrichtungen aufweisen, die einen Winkel von circa 70°- 110° zueinander aufweisen, wobei die Fahrzeugscheibe weiterhin eine Verzögerungsleitung (VZL) aufweist, um Signale der ersten Antennenstruktur (ANT1) gegenüber Signalen der zweiten Antennenstruktur (ANT2) zu verzögern, wobei die Fahrzeugscheibe weiterhin einen Koppler (K) aufweist, um die verzögerten Signale der ersten Antennenstruktur (ANT1) und Signale der zweiten Antennenstruktur (ANT2) zusammenzuführen, um ein zirkular polarisiertes Signal aufzufangen.
(EN)
The invention relates to a vehicle pane having a first substrate (GS1) and at least one first electrically conductive coating (LS1), the vehicle pane having a black printed portion in at least one section at the edge of the vehicle pane, wherein: at least part of the first electrically conductive coating (LS1) lies behind the black printed portion; a first antenna structure (ANT1) and a second antenna structure (ANT2) are provided in the section of the first electrically conductive coating (LS1) lying behind the black printed portion; both the first antenna structure (ANT1) and the second antenna structure (ANT2) have preferred directions at an angle of approximately 70°- 110° in relation to one another; in addition, the vehicle pane has a delay line (VZL) in order to delay signals of the first antenna structure (ANT1) in relation to signals of the second antenna structure (ANT2); and the vehicle pane also has a coupler (K), to combine the delayed signals of the first antenna structure (ANT1) and signals of the second antenna structure (ANT2) in order to pick up a circularly polarised signal.
(FR)
La présente invention concerne une vitre de véhicule, comprenant un premier substrat (GS1) et au moins une première couche électroconductrice (LS1). La vitre de véhicule comprend une impression en noir au niveau d'au moins un secteur au bord de la vitre de véhicule, la première couche électroconductrice (LS1) étant disposée au moins par secteur derrière l'impression en noir. Dans le secteur de la première couche électroconductrice (LS1), qui est disposé derrière l'impression en noir, sont disposées une première structure d'antenne (ANT1) et une seconde structure d'antenne (ANT2). La première structure d'antenne (ANT1) et la seconde structure d'antenne (ANT2) comprennent chacune des directions préférentielles qui forment un angle d'environ 70° à 110° entre elles. La vitre de véhicule comprend en outre une ligne à retard (VZL) pour retarder des signaux de la première structure d'antenne (ANT1) par rapport à des signaux de la seconde structure d'antenne (ANT2). La vitre de véhicule comprend en outre un coupleur (K) pour regrouper les signaux retardés de la première structure d'antenne (ANT1) et des signaux de la seconde structure d'antenne (ANT2) pour capter un signal à polarisation circulaire.
