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.
