Slow-Wave Substrate Integrated Waveguide

IEEE Transactions on Microwave Theory and Techniques, 2014
This paper describes a new concept of substrate integrated waveguide (SIW): a slow-wave substrate integrated waveguide (SW-SIW). Compared to a conventional SIW, the proposed topology requires a double-layer substrate with a bottom layer including internal metallized via-holes connected to the bottom conductive plane. The slow-wave effect is obtained by

Fishbone substrate integrated waveguide structures

AEU - International Journal of Electronics and Communications, 2019
Abstract In this paper, a new substrate integrated waveguide (SIW) structure is introduced. This structure uses some oblique slots on the top surface of the conventional SIW structure. These slots reduce the cut off frequency without affecting the width of the SIW structure. The results show that these slots are non-radiative.

Substrate integrated waveguide transmitter design

2013 Asia-Pacific Microwave Conference Proceedings (APMC), 2013
In this paper, two novel substrate integrated waveguide (SIW) transmitters, in Ku band and K band respectively, based on low-temperature co-fired ceramic (LTCC) technology, are proposed. A Ku band SIW filter with elliptic response is located in the input of the Ku band single channel transmitter, as well as SIW transmission lines embedded in LTCC ...

Substrate Integrated Waveguide Diplexer Design

2020
This chapter implements the microwave diplexer circuit model established in Chapter 4, using the twenty-first substrate integrated waveguide transmission line technology. No separate junction (resonant or non-resonant) was utilised in achieving the diplexer, as the use of an external junction for energy distribution in a diplexer normally increases ...

Development of substrate integrated waveguide power dividers

CCECE 2003 - Canadian Conference on Electrical and Computer Engineering. Toward a Caring and Humane Technology (Cat. No.03CH37436), 2004
Two classes of substrate integrated waveguide (SIW) power divider are presented, namely, Y- and T-types. Using arrays of via, the SIW power dividers and microstrip transitions are integrated on the same substrate. Design models are presented respectively for the Y- and T-junctions.

Multilayer Substrate Integrated Waveguide Six-Port Circuit

Radioelectronics and Communications Systems, 2018
In this paper a new design of a six-port circuit based on multilayer substrate integrated waveguides (SIW) is presented. This design is based on the use of a multilayer structure aimed at reducing the dimension of the circuit while conserving the performances of the component.

Substrate integrated waveguide filters and mechanical/electrical reconfigurable half-mode substrate integrated waveguide filters

Journal of Electromagnetic Waves and Applications, 2012
In this paper, novel evanescent mode substrate integrated waveguide (SIW) and half-mode substrate integrated waveguide (HMSIW) filters are proposed, and their applications to mechanical and electrical reconfigurable bandpass filters (BPFs) are studied. SIW and HMSIW loaded with coupled complementary split-ring resonators achieve forward electromagnetic

Multilayered substrate integrated waveguide (MSIW) elliptic filter

IEEE Microwave and Wireless Components Letters, 2005
This letter presents the design and experiment of a novel elliptic filter based on the multilayered substrate integrated waveguide (MSIW) technique. A C-band elliptic filter with four folded MSIW cavities is simulated by using high frequency structure simulator software and fabricated with a two-layer printed circuit board process, the measured results

Meshed-conductor substrate integrated waveguide

2012 Asia Pacific Microwave Conference Proceedings, 2012
Low temperature co-fired ceramic (LTCC) is the favored manufacturing technology for millimeter-wave substrate integrated waveguide (SIW) systems. SIW consumes a significant quantity of LTCC conductor material, typically gold or silver, as the width of substrate integrated waveguide is set according to the TE10 mode cut-off frequency. However, the solid

Rotated Half-Mode Substrate Integrated Waveguide

2013 Loughborough Antennas & Propagation Conference (LAPC), 2013
This paper outlines a new variant of a Half-Mode Substrate Integrated Waveguide which enables direct interaction with the wave energy; the rotated Half-Mode SIW. SIW discontinuities are normally vias, but the rHMSIW allows SIW discontinuities to be fabricated directly in copper and hence improved manufacturing tolerances.
