Abstract
A waveguide for use in apparatus for receiving transmitted data signals is provided. The waveguide includes first, second and third channels with the received data entering the first channel and components of the received data, signals being selectively deflected from the first channel into the second or third channels. The form of the components depends on whether the data signals have circular or linear polarity. The components leave the waveguide in substantially the same phase as which they entered the waveguide thereby allowing the same to be subsequently processed. The provision of the waveguide allows the receiving apparatus to be used to receive data signals with either circular and/or linear polarity and be subsequently processed.
