ORTHOGONAL MODE ELECTROMAGNETIC WAVE LAUNCHER ABSTRACT A launcher (20) of cross-polarized electromagnetic radiation is provided with increased bandwidth by inserting a set of axially directed ridges (50-56) on the interior surfaces of waveguide walls (28-34) of the launcher (20) for concentrating electric fields of radiations of the different polarizations. A first radiation radiated by a probe (62) in a back section (68) of the launcher waveguide (26) propagates forward into a front section (66) of the launcher waveguide (26). A second radiation is radiated into the front section (66) by a probe (64) therein, there being a vane (58) disposed in the front section (26) for inhibiting the propagation of the second radiation into the back section (68). The front section (66) is flared to provide a larger exit aperture at a front end of the front section (66). A second and a fourth of the ridges (54, 56) are tapered towards the back section (68) to permit a smooth transition in the propagation of the first radiation into the front section (66).
