Feb 13, 2017 · The lecture presents the results of an investigation of leaky wave antennas designed on a substrate integrated waveguide. The interest is given to three antenna types: an antenna radiating from a wide longitudinal slot etched in the top waveguide wall, a SIW CRLH leaky wave antenna, and a dual band SIW CRLH leaky wave antenna.

the SIW. Longitudinal slots elements were chosen for this design to minimize cross-polar radiation [9]. By contrast, other researchers have used tilted slots [3] or bowtie slots [6], which result in substantial cross-polarization and degraded sidelobe levels. A Frequency-Scanning Substrate-Integrated-Wave- Current and Future Research Trends in Substrate Integrated ... [9]. SIW are integrated waveguide-like structures fabri-cated by using two periodic rows of metallic vias or slots connecting the top and bottom ground planes of a dielectric substrate (Fig. 1). The SIW scheme belongs to the family of substrate integrated circuits that include other substrate integrated structures such as substrate integrated image
