A resonant load is inserted in each end of a continuous curved slot of calculated design in the broad face of a waveguide for improving the electrical characteristics, reducing radiation pattern beamwidth, and extending the useful range of overall slot length. The permittivity and permeability of the load material are controlled to present a matched termination to the field in the slot thereby eliminating standing waves on the slot and improving aperture distribution.
