“…E-plane couplers are also available in SIW technology with potentially wider frequency band characteristics [27,28], but the use of coupling slots (resonant narrow slots usually) or holes (with typically rectangular or elliptical shapes) are known to introduce strong voltage magnification (field strength normalized to the input field) in the coupling zone thus resulting in limited power handling, according to standard multipaction design rules based on the parallel- plate assumption [33]. In practice, fringing fields generated around slots tend to significantly increase the voltage necessary to induce multipactor [34].…”

Abstract-This paper introduces a novel design of Butler matrix in substrate integrated waveguide (SIW) technology with wide frequency band characteristics. Butler matrices are particularly useful in advanced antenna design and characteristics such as wideband operation, power handling, manufacturing, integration, cost, etc. are typical issues to be addressed in many applications. The proposed planar 4 × 4 Butler matrix provides an interesting solution to most of these issues. Wideband operation is achieved thanks to improved cross-couplers. These components are also characterized by higher power handling when compared to E-plane couplers. The use of SIW technology enables to reduce insertion losses compared to other printed technologies, while maintaining most advantages of such technologies such as high integration, manufacturing simplicity, low weight, etc. The proposed design is fully described, from the elementary building blocks to the full assembly performances. The design is optimized for operation in Ku-band with a center frequency at 12.5 GHz. A prototype of the 4 × 4 Butler matrix is manufactured, and good performances are confirmed over 24% relative frequency bandwidth. Potential use of this sub-system in multibeam antenna design is also discussed.

“…Therefore, this paper presents a MMT approach for the analysis and design of SIW components with square via holes. The numerical procedure follows fundamental MMT principles [8] and uses an all-dielectric waveguide as a lowreflective SIW feed [9]. Fig.…”

A mode-matching approach is presented for the analysis of substrate-integrated waveguide (SIW) circuits. The numerical technique takes advantage of recently developed fabrication techniques employing rectangular-shaped via holes. Discontinuity models involving all-dielectric waveguides and sections with arbitrary numbers of vias are presented and combined into a powerful analysis tool which can be used straightforwardly for the design of SIW components. The influence of the overall substrate width on the circuit performance is investigated. It is found that the computational domain can be significantly reduced without impacting on the computed performances. A design example involving a back-to-back impedance transformer is presented. The results are verified by comparison with the commercially available field solver CST Microwave Studio.

“…To integrate this technology with two-dimensional antenna arrays [9], however, coupling between stacked SIW components must be facilitated. Attempts to incorporate multilayered SIW circuits for antenna feed networks have been made in [8,10] in the form of an E-plane directional couplers. This article presents simplified design guidelines for dualand triple-layered Riblet-Saad SIW E-plane couplers.…”

Broadband design of a small nonsymmetric ground k/4 open slot antenna, Microwave J 50 (2007), 110-120. 18. W.S. Chen and K.Y. Ku, Band-rejected design of the printed open slot antenna for WLAN/WiMAX operation, IEEE Trans AntennasABSTRACT: A simplified design procedure for dual-and triple-layered Riblet-Saad directional couplers in substrate-integrated waveguide (SIW) technology is presented. Emphasis is placed on a design that considers ease of fabrication and includes interface ports such as microstrip-to-SIW transitions with straight, bent, and mitered microstrip lines. Designs are performed in an HFSS environment, which is verified by comparison with an independent field-solver simulation.
