“…The differences between the magnitude of the S 12 and S 13 are not negligible ones. However, S 12 and S 13 moduli are typical values, reported in literature for SIW couplers designed as 3 dB power dividers [8,13,14,19,25]. Table 3 reports the measured performance of couplers #6-#8, where C is the coupling coefficient mean value, f c is central frequency, S 41 modulus is evaluated in the range from 10.5 GHz to 12.5 GHz.…”

“…Many papers [8,12,13,[19][20][21][22][23][24] report couplers made using substrates with dielectric constants from ε r = 2.08 to ε r = 2.94 (e.g., Duroid) and exhibiting excellent characteristics. For example, in [8] Duroid single-layer planar directional couplers based on substrate integrated waveguide (SIW) technology have been presented.…”

“…The SIW couplers have shown good performances with broad operation bandwidth, low insertion loss, low return loss and high isolation. In [19] a half mode substrate integrated waveguide (HMSIW) 3 dB coupler has been proposed. The HMSIW Duroid coupler has exhibited better characteristics than those obtained by using conventional SIW technique, i.e., lower insertion loss, larger bandwidth, higher compactness (nearly half of size).…”

Abstract-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 high dielectric constant, allowing the reduction of the device size. The coupler requirements are 90-degree phase shift between the output and the coupled ports and frequency bandwidth from about 10.5 GHz to 12.5 GHz. The design and optimization of the couplers have been performed by using the software CST Microwave Studio c . Eight different coupler configurations have been designed and compared. The better three couplers have been fabricated and characterized. The proposed SIW directional couplers could be integrated within more complex planar circuits or utilized as stand-alone devices, because of their compact size. They exhibit good performance and could be employed in communication applications as broadcast signal distribution and as key elements for the construction of other microwave devices and systems.

Abstract-By inserting a dielectric layer, covered by a grounded metal plane, into a hollow rectangular waveguide (HRWG), a planar rectangular waveguide (PRWG) is structured. It is a new candidate solution for both MMIC and hybrid planar RF circuit applications. An intensive numerical analysis of the PRWG is conducted by a 2-D FDTD method. The propagation characteristics of the PRWG with different physical dimensions and electrical parameters are presented. This analysis shows that the PRWG can give an alterable single mode working bandwidth for dominant mode compared with the HRWG, and the size of the transverse section of the PRWG is smaller than the HRWG under the same cutoff frequency of dominant mode.

A dual‐band substrate integrated coaxial line (SICL) 3‐dB branch‐line coupler and its compact realization are proposed in this letter. The SICL coupler with the compact structure shows a comparable performance and great size reduction compared with the conventional structure. The simulated and measured results match very well. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:1246–1249, 2015
