Full‐wave modelling of microstrip line and its sensitivities on lossy multilayer dielectric substrate and superstrate with laminated ground plane

Abstract

SUMMARYThis paper presents a new formulation useful for modelling multilayered microstrip and its geometrical sensitivities with laminated ground plane. New integral equations are formulated, in the spectral domain, using the exact dyadic Green's function of bianisotropic planar media. We have applied a dynamic twodimensional least-square algorithm as an optimization procedure. Obtained results agree well with those of other approaches.

A generalized CAD model for the full‐wave modelling of microstrip line and its regular and irregular discontinuities

“…Finally, we have calculated the phase of the transmission coefficient of the discontinuity bentstub of W 1 ¼ 1:35 mm; L 1 ¼ 1:38 mm; W 2 ¼ 1:32 mm and L 2 ¼ 2:11 mm connected to a microstrip line e r ¼ 10:86; h ¼ 1:27 mm and W ¼ 1:33 mm: As shown in Figure 10, our results are in agreement with those of the approach [22] and those of Jackson [21] and its measurements.…”

“…calculated the longitudinal and transversal current distributions and the reflection and transmission coefficients near the discontinuity. In order to compare our results of the stub with those of Jackson [21] and its measurements and with those of Reference [22], we study the stub discontinuity of W 1 ¼ 1:4 mm and L 1 ¼ 4:98 mm connected to a microstrip line of e r ¼ 10:86; h ¼ 1:27 mm and W ¼ 1:45 mm: As shown in Figure 9(a), the results of the different approaches and the measurement, of the transmission coefficient argument ArgðS 21 Þ calculated versus frequency, are in good concordance.…”
