Quasistatic RLCG parameters of lossy microstrip line for CAD application

This paper presents a closed-form model for primary line constants, i.e., R , L, C, and G, for a lossy microstrip line for CAD application. The present model easily determines the microstrip line characteristics, i.e., the eff ective dielectric constant, complex characteristic impedance, and total att enuation due to dielectric and conductor losses. The model has an average a ccuracy of 1% ns compared to the experimental results and the results of ot her numerical methods. (C) 2001 John Wiley & Sons, Inc.
