In this paper a novel compact Substrate Integrated Waveguide (SIW) filter is proposed. A wideband band pass filter for microwave and millimeter-wave systems is investigated at 80 GHz center frequency with 10.5% fractional bandwidth. A Conductor backed coplanar waveguide is inserted in Substrate Integrated Waveguide (SIW) structure as transition to achieve sharper skirt characteristics. Simulate...

In this article, we present a substrate-integrated waveguide-based band-pass filter with wide stop-band rejection property. This band-pass filter is made up of two substrate-integrated waveguide cavities, which couple to each other by an aperture on their common waveguide side wall. By using the empirical formula [19] for obtaining the equivalent rectangular waveguide dimensions, the substrate ...

In this paper, the power dissipated through different loss mechanisms including dielectric, conductor and radiation loss is calculated for the substrate integrated waveguide (SIW) and modified substrate integrated waveguide (MSIW). The applied computational method being appropriate for structures with periodic conducting parts allows one to calculate the integrals corresponding to these powers ...

This paper presents an overview of substrate integrated waveguide (SIW) design activities at the University of Victoria. Mode-matching techniques (MMTs) are employed to facilitate the design of planar SIW circuits as well as surface mounted waveguide (SMW) components. Active component integration and antenna design employ commercially available field solvers. Each category is highlighted by a s...

In this paper a new low profile Substrate Integrated Waveguide (SIW) probe-fed H-plane horn antenna structure with improved gain is proposed. The proposed antenna consists of two waveguides including a rectangular and a taper one, in which both, first and third modes of the structure are simultaneously excited leading to a uniform field distribution along the radiating aperture of the antenna a...
