AbstractDisclosed is a pane antenna installed in a heated window pane of a motor vehicle to receive frequencies above the high frequency range. The antenna includes at least one wire-shaped first antenna conductor extending across parallel heating conductors of a heating field. The crossing points of the first antenna conductor with heating conductors are preferably in galvanic contact to create a capacitive antenna region along the first antenna conductor. The capacitive antenna region is coupled via a second antenna conductor extending also perpendicularly to the heating conductors, to an antenna terminal arranged on the window pane in proximity to a rim. The window pane is surrounded by a conductive frame and a grounding point is created on the frame opposite the antenna terminal.
