Abstract: A distance measuring apparatus and method for calculating a distance in a conducting structure are provided. One distance measuring apparatus provides for calculating a distance between a reflection body in a conducting structure and an injection point provided on an end section of the conducting structure for electromagnetic waves is provided. The distance measuring apparatus includes a transmitting and receiving device with a conduction cross-over provided at the injection point for the coaxially-inductive coupling of the transmitting and receiving device to the conducting structure in order to inject an electromagnetic wave into the conducting structure and to decouple the electromagnetic wave reflected on the reflection body from the conducting structure. The distance measuring apparatus also includes an analysis device for calculating a distance between the injection point and the reflection body from the phase difference between the injected electromagnetic wave and the decoupled electromagnetic wave.

Abstract: A diplexer for a reflector antenna includes a common circular signal waveguide to transmit and receive signals. The signal waveguide includes first and second ends with a common port provided at the first end. A waveguide arrangement is disposed coaxially relative to the signal waveguide in the region of the second end of the signal waveguide. A cylindrical coupler section is disposed between the first and second ends of the signal waveguide, and connects the waveguide arrangement to the common signal waveguide. In order to create a first and second coaxial waveguide port, the waveguide arrangement includes a first circular waveguide, an inner conductor is disposed inside, in which a first signal can propagate when the diplexer is operating, and a second circular waveguide, surrounding the first waveguide, in which a second signal can propagate at a lower frequency than the first signal when the diplexer is operating.
