Abstract: The present invention relates to a roof antenna for a vehicle, comprising a main body, a cover device and a circuit board (PCB layer), wherein the main body is made of metal, wherein at least one mm wave antenna is arranged between the metal main body and the printed circuit board.

Abstract: The present disclosure relates to a method for operating a communication device of a motor vehicle. The communication device communicates with at least one other motor vehicle or at least one stationary receiver, wherein for this purpose, a wireless communication connection based on linearly polarized electromagnetic waves is used. In order to use the communication connection, a transmission signal is transmitted with a specified transmission power by the communication device, and the transmission power is reduced on the basis of the reception of a reception signal by means of the communication device, said reception signal using electromagnetic waves which are at least partly orthogonally polarized relative to the linearly polarized electromagnetic waves.

Abstract: The invention relates to an antenna system for an outer wall of a vehicle, comprising an antenna assembly having a housing, a base body made of an electrically insulating material, and a support plate, wherein electronic components for a plurality of antenna modules are arranged on the base body.
