Abstract
The invention relates to a mobile antenna for a plurality of radio services in the form of a dipole or monopole, with an antenna conductor and with at least one flatly designed roof capacity disposed substantially vertical relative to the antenna conductor for a first radio service with polarization disposed vertically relative to the roof capacity. The roof capacity is designed in the form of a conductive board or a thin conductive layer. In order to create an antenna function for at least one additional radio service with polarization oriented parallel with the roof capacitance, at least one slot is incorporated in the conductive board or layer with the slot length selected to form a suitable impedance bandwidth. In order to decouple signals of an additional radio service, first and second connection points are formed on the edges of the slot, wherein the connecting points oppose each other.
