“…where W ( z ) is the width of the SIW line at the position z , s is the center‐to‐center distance between two consecutive vias, and d is the via radius as shown in Figure 1. In Rabaani and Boulejfen, 15 the accuracy of the SIW to rectangular waveguide approximation has been assessed. The presented work confirms that the propagation characteristics of an SIW line match well with those of the equivalent conventional rectangular waveguide with the same dielectric height and electric permittivity ε .…”

In this paper, a new method-of-moments-based approach is proposed for the analysis of non-uniform lossy substrate integrated waveguides (SIW) transmission lines. The approach incorporates Chebyshev expansion in the frequency domain to compute the scattering parameter matrix of the line. To validate the proposed approach of non-uniform structures are analyzed where two of them have been fabricated and measured. The analytical and measured S parameters were compared to those obtained through electromagnetic finite elementbased simulations. The good match observed between the two sets of results for a relatively reasonable number of basis functions confirms the accuracy and the fast convergence of the proposed approach. This makes it the most suitable for integration into computer-aided design tools.

“…This way, the SIW TL can be treated as a RGW. In reference , we investigated the efficiency and limitations of the waveguide equations in describing the behavior of a uniform SIW section. In has been proved that for frequencies above the cutoff frequency of the TE 10 mode and for a reasonable via hole diameter and spacing, the propagation characteristics of the SIW match well with those of the equivalent conventional RGW with the same dielectric height and permittivity.…”

A novel, low complexity approach for the analysis of nonuniform lossy substrate‐integrated waveguide transmission lines based on the method of moments is proposed. The approach uses frequency‐dependent basis functions derived from the structure's propagation characteristics. Two tapered structures are analyzed, fabricated, and measured to validate the proposed approach. The analytical results of the proposed approach for both structures are compared to those obtained by measurement and by three‐dimensional field simulation. Excellent agreement is observed between the three sets of results with simulation time savings on more than 98% and memory requirement reduction of more than 97%.

“…Figure 5a depicts the concatenation of the different defined blocks. Connected to the first and last block of the concatenation, there are two identical terminals whose characteristic impedance, Z in , is given by (1) [3], where D and S are the diameter and the separation between two consecutive conductive vias of the SIW, respectively.…”

A novel modelling technique to design microwave 3D-printable filters based on arbitrarily height-modulated substrate integrated waveguides (SIW) is presented in this paper. In the literature, different topologies have been already employed to design filters based on SIW. Nevertheless, none of these solutions have analyzed the behavior of the modulation of the height of the filters. This is due to the difficulty of manufacturing the prototypes with conventional procedures. In this paper, the techniques to design and manufacture these filters, provided with microstrip transitions for their validation, are presented.
