Abstract

In this article, a coplanar waveguide (CPW)‐based composite right/left‐handed transmission line (CRLH TL) is introduced. The structure is realized by parallel‐plate series capacitors (C) and shunt CPW stub inductors (L). Using a symmetric configuration for the unit cells along with searching for optimum values of LC components, we reduce the insertion loss and achieve wider LH‐bandwidth. For the symmetric CRLH TL, a LH‐passband extending from 1.3 to 4 GHz and a RH‐passband extending from 4 to 6.5 GHz are measured. © 2009 Wiley Periodicals, Inc.
