Abstract: The present invention concerns an antenna (20) with a layered structure, in particular a single or double layer antenna (20) integrated into vehicle-windshield having a conformal foil structure comprising a monopole arm (21) and ground plane arms (22, 23), wherein the antenna (20) has a transparency of 70%-90%.

Abstract: A slot antenna is formed between two body parts of a vehicle, with an antenna signal being tapped at an antenna signal tap point. One body part is capacitively coupled to a conductor of a radio frequency cable or a radio frequency connecting plug.

Abstract: A contacting system of a flat antenna conductor structure is provided which is integrated in a vehicle installation part, particularly a vehicle window. First contacting devices are provided which are arranged on the vehicle installation part and are connected with the antenna conductor structure. Second contacting devices are provided which are arranged on the vehicle body side on at least one contact base. The contacting of the first contacting device via the corresponding second contacting device takes place by a relative movement between the vehicle installation part and the contact base during the installation. At least one electric connection line, at least one signal processing circuit and at least one carrier are provided. At least the contact base is an integral component of the carrier. The at least one electric connection line connects the respective second contacting device with the corresponding signal processing circuit.

Abstract: The invention provides an aerial for a motor vehicle having an aerial base portion which can be fitted onto the body of a vehicle, and is provided with a capacitive ground coupling. According to the invention, the aerial base portion, ground coupling, aerial wire and the connected end of the high frequency line are embedded in a single component elastomer body which is provided with a locking configuration for locking in an opening of a wall of the body of the motor vehicle.
