1. A radiating waveguide comprisingan elongated waveguide having a transverse cross-section dimensioned to carry only the dominant mode at a selected operating frequency,one wall of said waveguide forming a continuous non-resonant longitudinal slot to produce a radiated field polarized perpendicularly to the slot,said slot extending substantially parallel to the axis of the waveguide and having a transverse dimension that is sufficiently narrow to substantially avoid the radiation of a field polarized parallel to the slot, said slot being dimensioned and located so that the amount of transverse currents intersected by the slot are sufficiently small to avoid significant radiation-attenuation of signals propagating longitudinally through the waveguide, andmeans for feeding the waveguide at one end thereof.
