The Substrate Integrated Waveguide (SIW) technology is an attractive approach for the design of high performance microwave and millimeter wave components, as it combines the advantages of planar technology, such as low fabrication costs, with the low loss inherent to the waveguide solution. In this study, a substrate integrated waveguide power divider, circulator and coupler are conceived and o...

Substrate integrated waveguide (SIW) is a new form of transmission line. It facilitates the realization of nonplanar (waveguide based) circuits into planar form for easy integration with other planar (microstrip) circuits and systems. This paper describes the design of an SIW to microstrip transition. The transition is broadband covering the frequency range of 8 – 12GHz. The measured in-band in...

planar slot antenna using Substrate Integrated Waveguide technology (SIW) is proposed in this paper. SIW has all the advantages required for a small size antenna package: Lowcost, high-performance and ease of integration. The SIW antenna with tapered microstrip-SIW transitions are integrated and synthesized on a single substrate. This structure is designed with Finite Element Method (FEM) using...

this paper describes the design of a 2x2 micro strip patch antenna array in the frequency of 9.5ghz for radar applications, using substrate integrated waveguide, siw, for feeding network. the micro strip patches are aperture-coupled with the feeding network of siw. the feeding network consisting of a perpendicular coax-to-siw transition and two y-junction power dividers. the antenna is simulate...

IW circuits are considered quasi3D (2,5D) metal-dielectric circuits. They have a high level of integration circuits, the metal and dielectric losses moderated and the precision of manufacturing for microwave applications [1]-[3]. The architecture of these structures consists in adding to the planar circuits a network of metallic via-hole integrated in the dielectric layer. The via-holes replace...
