Substrate integrated waveguide (SIW) linear phase filter
IEEE Microwave and Wireless Components Letters, 2005 A planar four-pole linear phase filter centered at 10GHz based on substrate integrated waveguide (SIW) is proposed. The filter is composed of four side-by-side horizontally oriented SIW cavities, which are coupled in turn by evanescent waveguide sections with three direct coupling and one cross coupling between the first and fourth SIW cavities.

Compact super-wide bandpass substrate integrated waveguide (SIW) filters
IEEE Transactions on Microwave Theory and Techniques, 2005 It is known that the substrate integrated waveguide (SIW) features high-pass characteristics of the conventional waveguide, and a periodic structure (PS) generally presents bandstop characteristics. Therefore, a super-wide-band bandpass characteristic should be realized by combining some sort of PS into the SIW.

Miniaturized Substrate Integrated Waveguide (SIW) Power Dividers
IEEE Microwave and Wireless Components Letters, 2016In this letter, compact substrate integrated waveguide (SIW) power dividers are presented. Both equal and unequal power divisions are considered. A quarter-wavelength long wedge shape SIW structure is used for the power division. Direct coaxial feed is used for the input port and SIW-to-microstrip transitions are used for the output ports.

Substrate Integrated Waveguide (SIW)
2021 XXXIVth General Assembly and Scientific Symposium of the International Union of Radio Science (URSI GASS), 2021Guided-wave structures are no doubt the most fundamental building elements of high-frequency antennas, circuits and systems. They are usually composed of metallic and dielectric topologies or mixed forms of both, which are made in the form of planar and non-planar geometries, depending on design approaches, processing technologies and application ...

Investigation on Tolerances of Substrate Integrated Waveguide (SIW)
2007 Asia-Pacific Microwave Conference, 2007In this paper, the substrate integrated waveguide (SIW) is investigated into the effects of tolerances using the sensitivity approach. The changes in characteristics of transmission line due to the tolerances of its parameters have been analyzed to evaluate the worst case behavior.

A broadband substrate integrated waveguide (SIW) filter
2005 IEEE Antennas and Propagation Society International Symposium, 2005An eleven-stage broadband SIW filter has been designed, fabricated and measured. The measured results show that the SIW filter can be operated from 9.25 GHz to 11.25 GHz with good selectivity performance. The filter has a small size, low weight, and can be integrated with other SIW components without any transitions.

A transition from substrate integrated waveguide (SIW) to rectangular waveguide
2009 Asia Pacific Microwave Conference, 2009In this work, a simple and compact transition from substrate integrated waveguide (SIW) to traditional rectangular waveguide is proposed and demonstrated. The substrate of SIW can be easily surface-mounted to the standard flange of the waveguide by creating a flange on the substrate.
