Abstract : A dielectric waveguide of rectangular cross-section has periodically spaced, transverse slots in its upper surface. When traveling waves of varying millimeter wavelength frequencies are applied to the waveguide, the slots perturb the waves resulting in radiation having a main lobe that scans as the frequency changes. The antenna is made rigid by the use of a dielectric support. (Author)
