The microstrip lines act as ... slots forming the microstrip lines extend up to the via post walls. The utilization of longitudinal Design of radome-covered substrate integrated waveguide ... A design of a radome-covered slot antenna array based on Substrate Integrated Waveguide (SIW) technology is presented in this paper. The design method consists of the analysis of an isolated radiating element, the synthesis of a linear array, the optimization of a planar array, and the development of a power divider with a transition from a feeding metal waveguide to an SIW.
Multilayered or stacked substrates and vias for suppressing leakage into the substrate are less well fabricated in practice.This paper presents an analysis of a flat waveguide with a longitudinal slot, reports new theoretical findings, illustrates characteristics of the line and predicts its applicability.

[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

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- Design and modeling of a linear array of longitudinal ... 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. The concept of SIW has been proposed and used in which an "artificial" waveguide is synthesized and constructed with linear arrays of metallized via-holes or posts embedded ... ANALYSIS AND DESIGN OF SLOTTED SUBSTRATE INTEGRATED ... This thesis presents novel traveling wave conformal shunt slot arrays on cylindrical substrate integrated waveguide (CSIW) placed on a cylindrical surface in the circumferential direction at K-band. Mutual couplings of longitudinal slots on broad wall of CSIW are formulated and active admittance formulas of the slots are derived
Substrate integrated Waveguide – Base for Leaky Wave 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. Design of radome-covered substrate integrated waveguide A design of a radome-covered slot antenna array based on Substrate Integrated Waveguide (SIW) technology is presented in this paper. The design method consists of the analysis of an isolated radiating element, the synthesis of a linear array, the optimization of a planar array, and the development of a power divider with a transition from a feeding metal waveguide to an SIW. Compact Two-Layer Slot Array Antenna for K-Band A novel two-layer slot array antenna based on substrate integrated waveguide (SIW) technology was designed and simulated. Unlike already reported SIW slot arrays, the present design achieves considerable reduction in size by using a feed waveguide placed underneath the slot array and coupled through slanted slots to branches of the array.
