2016 Second International Conference on Computational Intelligence & Communication Technology (CICT), 2016
This paper shows critical review of substrate Integrated waveguide (SIW) technology. Dielectric filled waveguide is converted into SIW with periodic arrangement of metallized holes on both sides of the it. SIW exhibit high pass response of conventional waveguide and band stop characteristics of periodic design. So filters designed using SIW exhibit less loss, less cost , less weight, high quality factor and high power handling capability. Various SIW passive and active circuits has been studied. Numerical method for modeling and design of SIW components is shown. A SIW has been designed showing insertion loss less than 0.1 dB. Design solutions for loss reduction are also discussed. Future design scope mainly aiming at Systems-on-Substrate integration of SIW components at higher frequencies including Ultra Wide Band range are also discussed.
A Review on SIW and Its Applications to Microwave Components
Electronics MDPI, 2022
Substrate-integrated waveguide (SIW) is a modern day (21st century) transmission line that has recently been developed. This technology has introduced new possibilities to the design of efficient circuits and components operating in the radio frequency (RF) and microwave frequency spectrum. Microstrip components are very good for low frequency applications but are ineffective at extreme frequencies, and involve rigorous fabrication concessions in the implementation of RF, microwave, and millimeter-wave components. This is due to wavelengths being short at higher frequencies. Waveguide devices, on the other hand, are ideal for higher frequency systems, but are very costly, hard to fabricate, and challenging to integrate with planar components in the neighborhood. SIW connects the gap that existed between conventional air-filled rectangular waveguide and planar transmission line technologies including the microstrip. This study explores the current advance-ments and new opportunities in SIW implementation of RF and microwave devices including filters, multiplexers (diplexers and triplexers), power dividers/combiners, antennas, and sensors for modern communication systems.
Design and Analysis of Substrate Integrated Waveguide
Proceedings of the 1st International Conference on Sustainable Materials, Manufacturing and Energy Technologies, 2022
At microwave and higher frequencies, the need for highly efficient, low cost, high gain, easy to construct, and compact antennas for communication applications has increased. Although, Substrate Integrated Waveguides (SIW) technology is the emerging technology for radar and satellite applications. SIWs are widely employed as interconnection in antennas particularly leaky wave antennas, high speed circuits, directional couplers, and filters because they are having low loss properties of their typical metallic waveguides. A SIW with cylindrical slots is suggested in this work, as well as its integration with a tapered microstrip transmission line.
Review of substrate-integrated waveguide circuits and antennas
IET Microwaves, Antennas & Propagation, 2011
Substrate-integrated waveguide (SIW) technology represents an emerging and very promising candidate for the development of circuits and components operating in the microwave and millimetre-wave region. SIW structures are generally fabricated by using two rows of conducting cylinders or slots embedded in a dielectric substrate that connects two parallel metal plates, and permit the implementation of classical rectangular waveguide components in planar form, along with printed circuitry, active devices and antennas. This study aims to provide an overview of the recent advances in the modelling, design and technological implementation of SIW structures and components.

The analysis is achieved using the two dimensional quick finite element method (2D-QFEM) programmed under Matlab environment. The obtained results are verified by comparison with HFSS and CST Micro Wave Studio commercial software. The return losses, transmission coefficients and the field's distribution are exposed in this article. The numerical simulation program can provides useful design information as well as physical insights for frequencies way up in the millimeter range. As result, this method can analyze complex structure in the short time. Index Terms-Millimeter Wave Substrate Integrated Waveguide (MWSIW), two dimension Finite Element Method 2D-FEM, Analysis.
In this work, a propagation performance analysis for the substrate integrated waveguide structures (SIW) is exposed. The effectiveness of these types of guides is determined by a numerical simulation for a SIW guide operating in X-band, where high power part can be transmitted. The advantage of this technology is that it combined the advantages of traditional waveguides and micro strip lines. In this work the presentation of S parameters resulting from the analysis of a SIW wave guided signed to operate in X-band which is spread out between [ 8-12] GHz, this analysis will be carried out by the simulation of a SIW waveguide under CST with a validation of the results by Momentum Agilent. An application of the technique HMSIW X-band will be presented while comparing the results obtained by that obtained by a simple SIW.

This paper offers an approximate, but very convenient and accurate, manner to find the desired strip width for substrate integrated gap waveguide (SIGW) with a given characteristic impedance and the conductor and dielectric attenuation constants, without any complicated manual calculations or time-consuming full-wave simulation and optimization iterations. Moreover, the investigation of the transition between SIGW and microstrip lines will prove that an additional transition structure, such as a conventional microstrip taper, is not required any more at millimeter-wave frequencies for the desired transmission performance. This is a useful feature in circuit design and compactness. Both of the above works will be of great help to realize future feeding networks for SIGW antenna arrays or other types of cost-effective SIGW passive components at high frequencies. Two SIGW prototypes, working at Ka and V bands, are fabricated and offer experimental verifications, which present good agreement with the simulation results.

Losses in Waveguide and Substrate Integrated Waveguide (SIW) For Ku Band: A Comparison
IJMER
ABSTRACT- In this paper equivalent Substrate Integrated Waveguide (SIW) for a waveguide is designed. Different types of losses in the waveguide and the optimized SIW are calculated theoretically and a comparison is done between the two. The comparison proves that at millimeter wave frequencies the choice of dielectric becomes crucial for a waveguide design and SIW is preferable to be used at these frequencies because the leakage losses decrease significantly.
