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.
In this thesis, the design of a broadside resonant linear array antenna of longitudinal slots on substrate integrated waveguide (SIW) for uniform aperture distribution and for a symmetric tapered distribution is presented.
A schematic view of an integrated waveguide is shown in Fig. 1. Fig.1: Geometry of the substrate Integrated Waveguide In this paper, the commercial software package “HFSS” based on the Finite Element Method (FEM) has been applied to the analysis of a single longitudinal slot antenna with tapered transition. 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. 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
