Antenna device, transceiver apparatus, compensator apparatus, vehicle, and method for operating an antenna device

An antenna device comprising a transceiver apparatus and a compensator apparatus, wherein

• a transceiver terminal of the transceiver apparatus is connected by a connecting apparatus to a compensator terminal of the compensator apparatus,
• the transceiver apparatus is configured to output an output signal to be sent and/or receive a received input signal at the transceiver terminal,
• the compensator apparatus is configured to receive the output signal to be sent at the compensator terminal of the compensator apparatus, to amplify the output signal to be sent by an antenna amplifier unit of the compensator apparatus and to output it at an antenna terminal of the compensator apparatus, and/or
• to receive the received input signal at the antenna terminal of the compensator apparatus, to amplify the received input signal by the antenna amplifier unit of the compensator apparatus and to output it at the compensator terminal of the compensator apparatus, and
• the transceiver apparatus comprises a voltage regulator configured to provide an output voltage for feeding the compensator apparatus at the transceiver terminal, wherein
• the antenna device comprises a feed apparatus configured to capture an actual input voltage present at the compensator terminal, to compare the actual input voltage with a predetermined target input voltage for feeding the compensator apparatus, and to regulate the actual input voltage to the predetermined target input voltage by adjusting the output voltage provided by the voltage regulator.
