Abstract: A method for testing at least one antenna having a receiver module and a coupling module which is arranged between the antenna and the receiver module. The antenna and the receiver module are supplied with a noise signal as a test signal by the coupling module. An instantaneous transmission coefficient, which indicates the ratio between a first noise signal (which is passed to the test module via a first path without passing through the at least one antenna) and a second noise signal (which is passed to the test module from the noise source via a second path which passes via the at least one antenna) being determined, and being compared with a reference transmission coefficient, which is stored in a transmission matrix, by a test module. An arrangement for carrying out the method is also provided.

Abstract: An antenna arrangement for a vehicle comprises a plurality of individual antennas, at least one of which is arranged in a vehicle window. The vehicle has a cover unit for a free space between the window and a region in the vehicle interior, which cover unit comprises a metal body that forms a further antenna. A switching device controls switching between the antennas to optimize signal reception.

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.
