Abstract

A motor vehicle, especially a passenger vehicle, has a metallic body provided with a window opening receiving an antenna window. The antenna window has inner and outer panes bonded together by a bonding layer with an optically-transparent electrically-conductive solar central coating reducing transmission in at least a part of the solar energy range. At least one edge of the window is left free from the coating and in this region a slot antenna is formed. At least at one additional edge, the coating runs to that edge and is overlapped by the framing portion of the vehicle body and is coupled with a high-frequency coupling to the coating.
