Abstract: A vehicle window includes a glass pane, an electrically conductive functional component, at least two busbars, wherein the electrically conductive functional component is electrically conductively connected to the busbars such that when an electrical voltage is applied to the busbars, a current can flow through the electrically conductive functional component, a transponder having an antenna and a control unit for communicating with a reader, wherein the control unit includes a memory for storing identification data, wherein a reflector is associated with and spaced apart from the transponder for increasing an antenna gain of the antenna, wherein the reflector is formed at least partially by one of the two busbars.

Abstract: An antenna pane includes an electrically insulating substrate, an electrically conductive functional layer on a surface of the substrate, and an antenna structure, which includes an electrically conductive antenna layer for receiving and/or transmitting high-frequency antenna signals, the antenna layer being galvanically separated from the functional layer, wherein a high-frequency technical resistance between the antenna layer and the functional layer for high-frequency antenna signals is at least 10 ohm, wherein the antenna layer has a first connection region and the functional layer has a second connection region, and an insulating line that electrically divides the functional layer into a first and second functional layer zone that are galvanically separated from one another, but are coupled using high-frequency technology such that a high-frequency technical resistance for high-frequency antenna signals is less than 1 ohm, wherein the second connection region is contained in the second functional layer zone.
