Abstract

Broadside‐coupled substrate striplines represent an essential part of modern integrated circuits. In this article, we will illustrate modeling of inhomogeneous quasi‐TEM shielded broadside‐coupled substrate striplines using the finite element method (FEM). FEM is especially suitable and effective for the computation of electromagnetic fields in strongly inhomogeneous media. We illustrate that FEM is suitable and effective as other methods for modeling shielded broadside‐coupled substrate striplines. We specifically determine the capacitance per unit length, even mode impedance, odd mode impedance, and characteristic impedance of shielded broadside‐coupled suspended striplines. Excellent agreement with some results obtained previously is demonstrated. We extended the modeling by designing our own model of shielded broadside‐coupled inverted microstrip line and determine the capacitance per unit length, even mode impedance, odd mode impedance, and characteristic impedance. © 2008 Wiley Periodicals, Inc.
