EHF band linear antenna array based on surface wave transformation

H-shaped surface-wave waveguides in the form of combination of dielectric rod and rigid metal elements have been proposed for a basic element of diffraction radiation antennas designed for operation in conditions of increased mechanical loads and vibrations at frequencies above 80 GHz. The presented results of experimental studies include near-field distributions of the aperture, radiation patterns, gain factor and power losses in antenna characterizing the efficiency of the proposed approach.
