Abstract: An antenna system for motor vehicles includes a surface that comprises an electrically conductive medium. A recess is located inside the electrically conductive surface, with the electrically conductive surface being a periphery of the recess. At least one electrically conductive crosspiece is electrically conductively connected to the periphery and protrudes into the recess and extends in the direction of a second side, facing the first side, of the periphery and there ends, forming a gap with the periphery. This crosspiece divides the recess into first and second parts with a gap connecting the two parts. At least one electrical line in a part of the recess originates at a feed point, located on the crosspiece but is electrically separate from it. The electrical line extends in the part of the recess in the direction of the periphery and is capacitively coupled to the periphery.
