Abstract: | The crosstalk and coupling of the external fields on orthogonal microstrip transmission lines in different layers have significant
effects on signal quality in MMIC and PCBs. In this paper the crosstalk is analyzed in detail using both full-wave and quasi-static
methods. The used full wave method is mixed potential integral equation method of moment (MPIEMoM). Because of the weak coupling between lines, the effect of the incident plane-wave is studied by applying transmission
line theory in a scattered voltage formulation uses quasi-TEM propagation model for each interconnection and the exact distribution
of the incident electric field within the layers. Afterward, by using the predetermined lumped circuit model of the cross-region,
the effect of coupling between two lines is calculated and then applied to terminal voltages in 1–20 GHz frequency range which
results in the final terminal voltages. |
