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.

Diplexer for a reflector antenna

A signal branch for use in a communication system, in particular in a reflector antenna, for the transmission of microwave signals is provided. The signal branch includes a common signal wave guide for transmitting a transmission signal and a received signal that has one first end and one second end as well as an exterior and interior. Moreover, a plurality of transmission signal wave guides is provided for feeding the transmission signal, with the transmission signal wave guides being disposed on the exterior of the common signal wave guide in a symmetrically distributed manner and each being communicatively connected to the common signal wave guide. A plurality of receiver signal wave guides is provided for transmitting the received signal, with the receiver signal wave guides being symmetrically adjacent to the second end of the common signal wave guide and each being communicatively connected to the common signal wave guide.
