| 摘要 |
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. |

1. An antenna system comprising:
an electrically conductive surface that comprises an electrically conductive medium; a recess that is located inside the electrically conductive surface, as a result of which the electrically conductive surface acts as a periphery of the recess; at least one first electrically conductive crosspiece, which originates on a first side of the periphery and 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 with the periphery, forming a gap, as a result of which the recess is divided into a first part and a second part and the gap that connects the two parts; at least two electrical lines, of which a first electrical line originates in the first part of the recess at a first feed point, located on the first crosspiece but electrically separate from it, and a second electrical line originates in the second part of the recess at a second feed point located on the first crosspiece but electrically separate from it; the first electrical line extends in the first part of the recess in the direction of the periphery and is capacitively coupled to the periphery, and the second electrical line extends in the second part of the recess in the direction of the periphery and is capacitively coupled to the periphery. |
