Abstract
The application relates to an antenna device for transmitting high-frequency signals from or to a motor vehicle. The antenna device comprises a first radio module and a second radio module, which provide high-frequency signals for transmission via an antenna, and an antenna module comprising the antenna and a compensator. The antenna module is connected to the first radio module via a first antenna cable, and to the second radio module via a second antenna cable. The compensator is designed to modify a signal strength of the high-frequency signals in accordance with a control signal. The first radio module and the second radio module are designed to generate the control signal for controlling the compensator, wherein in order to control the compensator, the second radio module modulates the control signal for the first radio module onto the second antenna cable.
