An antenna arrangement comprises a dual-polarised turnstile antenna, which comprises a first and a second dipole antenna element, which are aligned perpendicular to one another. The first and second dipole antenna elements each comprises two dipole halves. The dipole halves of both dipole antenna elements comprise a dipole section and a coupling section, which are galvanically connected to each other and to a first end of a ground connection medium or a signal connection medium. The coupling sections each extend along the closest dipole section of the adjacent other first and/or second dipole antenna element, wherein a spacing gap is formed between a coupling side of the respective coupling section of the first and/or second dipole antenna element and the respective adjacent dipole section of the second and/or dipole antenna element.

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.
