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.

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 ...

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

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.

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

A planar diplexer using hybrid substrate integrated waveguide and coplanar waveguide

2017 IEEE 17th International Conference on Ubiquitous Wireless Broadband (ICUWB), 2017
This paper proposes a planar diplexer using hybrid substrate integrated waveguide (SIW) and coplanar waveguide (CPW). On the basis of hybrid SIW-CPW structure which possesses high quality factor, adjustable transmission zeros, and compact size simultaneously, further employing microstrip T-junction which also possesses high performance and compact size,

Microstrip-to-waveguide transition in planar form using a substrate integrated waveguide

2018 IEEE Radio and Wireless Symposium (RWS), 2018
Interconnection of waveguides or horn antennas to a printed circuit board (PCB) is still a challenge in modern system design. Currently, this requires high effort since the waveguide cannot easily be connected to a microstrip line or coplanar grounded waveguide.

Substrate integrated nonradiative dielectric waveguide

IEEE Microwave and Wireless Components Letters, 2004
A new substrate integrated circuits (SICs) fabrication technique is proposed for realizing nonradiative dielectric (NRD) waveguide circuits. This new technique called substrate integrated NRD (SINRD) guide allows the NRD guide be integrated within a dielectric substrate by drilling a pattern of air holes.

Substrate integrated waveguide phase shifter

2011 International Conference on Electronics, Communications and Control (ICECC), 2011
An analogue variable phase shifter on the substrate integrated waveguide (SIW) technique operating at 26 GHz is proposed which employs varactor diodes, properly coupled to the SIW coupler to achieve a continuous electronic control of the phase shift. A vertical transition between 50 Ohm SMA and SIW is used for direct coupling.
