Abstract:
A transmitting/receiving station which is configured to cooperate with at least one transponder and by means of a which a transmitting mode and a receiving mode can be carried out and which comprises:a transmission coil circuit comprising a transmission coil for the communication with a transponder transmission coil provided in a transponder; conductor means having a given characteristic impedance, which conductor means have a first end and a second end and are connected to the transmission coil circuit at the location of the second end; transmitting means which are configured to generate a request signal which in a transmitting mode can be transmitted by the transmission coil and can be received by the transponder and which are connected to the conductor means at the location of the first end of the conductor means; receiving means which are configured to receive an answer signal produced in the transmitting/receiving station in response to a request signal received by the transponder and which are connected to the conductor means at the location of the first end of the conductor means; and additional means which are interposed between the transmitting means and the receiving means and the first end of the conductor means, by which additional means the transmitting means and the receiving means are connected to the first end of the conductor means and by which additional means the first end of the conductor means has a matched termination for the answer signal produced in the transmitting/receiving station.
