Abstract
Disclosed is a dual polarized horn radiator, in particular for a cellular radio base station, having a first polarization and a second polarization that are fed separately via a first hollow waveguide and a second hollow waveguide. In a first aspect one of the hollow waveguides runs in the direction of beam to its opening into the horn radiator and in so doing has a cross-section that extends in projection onto the aperture plane partially within and partially outside the aperture opening of the horn radiator. In a second aspect the two hollow waveguides run in the direction of beam to their openings into the horn radiator, with at least one of the hollow waveguides having a transformation section by which its polarization in the aperture plane is rotated with respect to the other hollow waveguide before it opens into the horn radiator.
