Abstract: The motor vehicle has a glass roof, an antenna arrangement seated on this glass roof, and a metallic frame. An opening of the glass roof is located below the antenna arrangement and is covered thereby. The frame is located below the glass roof and forms a dome, which extends into the opening of the glass roof and to which the antenna arrangement is mechanically connected. A reflection surface associated with the antenna arrangement is attached on the lower side of the glass roof. The reflection surface has a grid structure made of intersecting lines extending transversely to the z direction. The lines are provided with a metallization which has a width of 0.5 to 2 mm. The intersecting lines delimit free fields, which are not metallized and have a maximum clear dimension of 3 to 15 mm.
