Extracting equivalent circuit parameters of a CRLH transmission line

Abstract

A method to determine the inductive and capacitive components of the series impedance and shunt admittance for configuring the equivalent circuit of a composite right/left-handed (CRLH) transmission line is proposed. This method uses Z matrices with multiple frequencies obtained via full-wave analysis of an actual CRLH transmission line unit cell structure. Results are presented for the application of the proposed approach to a CRLH microstrip line.
