Abstract
Microstrip transmission lines have received more interest and attention in microwave integrated circuit design. Analysis and electrical characterization of single and coupled microstrip lines have been a major focus for researchers in integrated circuit technology. In this article, we will illustrate modeling of the capacitance, inductance, and characteristic impedance of quasi‐TEM for open microstrip lines using finite element method with COMSOL multiphysics package. In this work, we determine the capacitance per unit length, inductance per unit length, and characteristic impedance of open microstrip lines (single‐strip, double strip, and three‐strip). We compare our results with those obtained by other methods and found them to be in agreement. © 2008 Wiley Periodicals, Inc.
