1. An electrically heatable antenna pane, comprisinga transparent pane;

  • a heating layer extending over a portion of a pane surface of the transparent pane and serving as a planar antenna for receiving and/or transmitting electromagnetic waves;

    a first busbar and a second busbar connectable to a voltage source, wherein the first busbar and the second busbar are connected with the heating layer;

    a first antenna connection that is electrically conductingly connected with the heating layer;

    a second antenna connection electrically conductingly connected with a section of the heating layer in direct contact; and

    the second antenna connection being galvanically and physically isolated from a portion of the heating layer outside and adjacent to the section,wherein in an operative condition and upon applying a supply voltage by the voltage source, a heating current flows over a heating field formed by the heating layer,wherein the section of the heating layer is electrically insulated from the rest of the heating layer by a heating-layer-free separation region, andwherein the section of the heating layer is capacitively coupled with an adjacent heating layer for a transmission of antenna signals.
