Abstract
A transmitting/receiving station is operable in a transmitting mode and a receiving mode. The transmitting/receiving station has a transmission coil circuit with a transmission coil and conductor having a given characteristic impedance, a first end, and a second end. The conductor has its second end connected to the transmission coil circuit and has its first end connected to transmitter means for generation of a request signal and to receiver for receiving an answer signal. Additional circuits are provided in order to guarantee that the first end of the conductor has a matched termination during the receiving mode.
