| Abstract: | Radiation patterns have been measured at 20.0, 22.0 and 25.2 GHz for a parabolic reflector illuminated from the prime focus by a linearly polarised feed radiating through a sub-reflector built from a stack of dielectric filled waveguides. The influence of the intervening guides on the radiation patterns is discussed. |
