A Composite Right/Left-Handed Transmission Line Implementing Quasi-Exponential Inductive Stubs

This paper proposes a composite right/left-handed (CRLH) transmission line structure implemented on microstrip and composed of interdigital capacitors and quasi-exponential inductive stubs (QEIS's). By replacing the more commonly used uniform transmission line stubs with QEIS's; the left-handed (LH) operating frequency band is increased
