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 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. 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.

Substrate integrated Waveguide – Base for Leaky Wave Antennas ... 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.
Microwaves101 | Substrate Integrated Waveguide Substrate Integrated Waveguide (SIW). 1. Introduction. In high frequency applications, microstrip devices are not efficient, and because wavelength at high frequencies are small, microstrip device manufacturing requires very tight tolerances. At high frequencies waveguide devices are preferred... Flat Waveguide with a Longitudinal Slot 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.
