Longitudinal slots on substrate integrated waveguide

A Frequency-Scanning Substrate-Integrated-Wave- guide ... 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.

[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

insertion loss is poor. Longitudinal slots are also used to couple energy from SIW to the waveguide. When the substrate with a longitudinal slot etched on the broad wall of the SIW is surface mounted to the standard flange of the waveguide, it acts as the window to transfer energy [7], however, the design suffers from narrow bandwidth of 800MHz.

Abstract: By etching longitudinal slots on the top metallic surface of the substrate integrated waveguide (SIW), an integrated slot-array antenna is proposed in this letter. The whole antenna and feeding system are fabricated on a single substrate, which takes the advantage of small size, low profile, and low cost, etc.
