FEASIBILITY INVESTIGATION OF LOW COST SUBSTRATE INTEGRATED WAVEGUIDE (SIW) DIRECTIONAL COUPLERS [PDF]

Progress In Electromagnetics Research B, 2014
In this paper, the feasibility of Substrate Integrated Waveguide (SIW) couplers, fabricated using single-layer TACONIC RF-35 dielectric substrate is investigated. The couplers have been produced employing a standard PCB process. The choice of the TACONIC RF-35 substrate as alternative to other conventional materials is motivated by its lower cost and ...

Modified Transition for Substrate Integrated Waveguide(SIW) Structures

Bulletin de la Société Royale des Sciences de Liège, 2016
In this paper a new X-band SIW to Microstrip transition based on SIW structure is proposed. The recent transition has better performance in terms of return loss than those of in the traditional Microstrip tapers transition. Chebyshev multi-section matching transformer is utilized in order to inter-stage network between Microstrip and SIW, whereof it is
