ABSTRACT:
A microwave radiator comprises a generally cup-shaped, at least partly metallic cavity with a cylindrical wall and an open end which is bounded by an edge or rim with two diametrically opposite axial projections, in the form of acute-angled cusps or rectangular teeth, which are bisected by an axial plane perpendicular to a dipole disposed inside the cavity. The open cavity end may be covered by a dielectric radome of frustoconical or stepped cylindrical configuration.
