Classification: CPC H | IPC H

Claim 0:
1. An antenna device for transmitting high-frequency signals from or to a motor vehicle, the antenna device comprising:
a first radio module and a second radio module, each configured to provide the high-frequency signals for transmission via an antenna;
an antenna module comprising the antenna for transmitting the high-frequency signals and a compensator, wherein the antenna module is coupled to the first radio module via a first antenna cable, and to the second radio module via a second antenna cable, and wherein:
the first antenna cable is configured to transmit a first high-frequency signal between the first radio module and the first antenna module;
the second antenna cable is configured to transmit a second high-frequency signal between the second radio module and the second antenna module;
the compensator being configured to modify a signal strength of the high-frequency signal and the second high-frequency signal in accordance with a first control signal and a second control signal respectively;
the first radio module is configured to generate the first control signal and the second radio module is configured to generate the second control signal for controlling the compensator; and
the second radio module is configured to modulate the first control signal for the first radio module for controlling the compensator onto the second antenna cable.
