1. Antenna pane that comprises at least one electrically insulating substrate, at least one electrically conductive functional layer on a surface of the substrate, and at least one antenna structure,
wherein the antenna structure comprises:
an electrically conductive antenna layer for receiving and/or transmitting high-frequency antenna signals, wherein the antenna layer is 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,
an insulating line, by means of which the functional layer is electrically divided into a first functional layer zone and a second functional layer zone, wherein the first and second functional layer zones 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.
