Abstract
According to the present invention, a waveguide assembly is provided and includes a common input waveguide aligned along a first axis. The input waveguide supports two frequency bands and one or more polarities, namely high and low band signals of two polarities which are typically supplied using a feed horn which is coaxially aligned with the input waveguide. The waveguide assembly also includes an output waveguide for supporting and discharging the low band signal (one or more polarities). The output waveguide extends along a second axis which is parallel to the first axis containing the input waveguide but is displaced therefrom. In order to accomplish this the waveguide assembly has two or more waveguides connecting the input waveguide to the output waveguide. The waveguides are disposed substantially perpendicular to the input and output waveguides such that the low band signal is fed into the input waveguide and then separated therefrom by being carried within one or more planes defined by the waveguides before being discharged through the output waveguide.
