Abstract (en)
[origin: EP1199771A2] The antenna has an impedance adapter circuit (15) and an amplifier circuit (16) that together form a circuit unit whose operation in the event of the failure of the amplifier circuit corresponds to the operation of the impedance adapter circuit. Its operation in the event of non-connection to an electrical supply corresponds to the operation of the impedance adapter circuit.
