Substrate Integrated Waveguide Corrugated Horn Antenna

Wireless Personal Communications, 2019
In this paper, a substrate integrated waveguide (SIW) H-plane horn antenna is proposed. We first optimize the antenna in size to obtain the maximum gain. The SIW horn antenna is then corrugated by adding some vias in order to further improve the beam pattern. We use half power beam width (HPBW) as a metric for this improvement.

Substrate integrated radiating waveguides with a coaxial feed

2nd European Conference on Antennas and Propagation (EuCAP 2007), 2007
In the present paper the study of coaxially fed substrate integrated waveguides (SIW) structures is presented. A novel feed configuration is proposed consisting of a ring loaded coaxial probe. The analysis of the structure is carried out with the method of moments and with FEM (HFSS). Applications to radiating SIW will be presented. (4 pages)

Composite right/left-handed substrate integrated waveguide and half-mode substrate integrated waveguide

2009 IEEE MTT-S International Microwave Symposium Digest, 2009
Composite right/left-handed (CRLH) substrate integrated waveguide (SIW) and half mode substrate integrated waveguide (HMSIW) are investigated and presented in this paper. By introducing series interdigital capacitors, which are realized by etching slots on the waveguide surface, both balanced and unbalanced CRLH waveguide transmission lines (TLs) are ...

Integration of SiON waveguides and photodiodes on silicon substrates

Applied Optics, 1992
Two methods of coupling integrated optical waveguides to photodetectors are investigated. As waveguides, SiON layers were deposited by low-pressure chemical vapor deposition on a thick isolation layer of thermally grown SiO(2) on silicon substrates.

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.

Millimeter-wave substrate integrated waveguide filters

CCECE 2003 - Canadian Conference on Electrical and Computer Engineering. Toward a Caring and Humane Technology (Cat. No.03CH37436), 2004
This paper presents the design and performance of millimeter waves filter realized with the SIW technology. Using the SIW, low-cost filter can be manufactured at millimeter-wave without tuning. A design methodology for Butterworth or Chebychev prototype is presented. Also a dual-mode filter is presented to improve the out of band rejection.

Variational Analysis of Folded Substrate-Integrated Waveguides

IEEE Microwave and Wireless Components Letters, 2015
An accurate numerical solution describing the propagation behavior of two types of folded substrate-integrated waveguide (FSIW) is demonstrated in this letter. The computation is based on a variational method which can be carried out efficiently by solving the stationary equation corresponding to each type of FSIW. The approach can be extended to solve

Design of Hollow Waveguide to Substrate Integrated Waveguide Transition in Multi-layer Substrate

2019 International Workshop on Electromagnetics: Applications and Student Innovation Competition (iWEM), 2019
Substrate Integrated Waveguide (SIW) is a low loss transmission line which can be used to connect an antenna to a backed RF circuit in the millimeter wave band. A multi-layer substrate is effective to integrate RF circuits and antennas. Therefore, a transition between a hollow waveguide and a SIW in multi-layer substrate is necessary.

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
