Abstract
A radiating waveguide comprises an elongated waveguide with a transverse cross-section dimensioned to carry only the dominant mode at a selected operating frequency. One wall of the waveguide forms a continuous non-resonant longitudinal slot or equivalent thereof to produce a radiated field polarized perpendicularly to the slot. The slot extends substantially parallel to the axis of the waveguide and has a transverse dimension that is sufficiently narrow to substantially avoid the radiation of a field polarized parallel to the slot.
