Theoretical Analysis of Composite Right/Left-handed Coupled Transmission Line Resonators

摘要

A novel resonator based on composite right/left-handed coupled transmission line (CRLH-CTL) is proposed. This novel resonator is analyzed using the even and odd mode ap-proach. It has been shown that there are two resonant frequencies which correspond to odd mode resonant frequency and even mode resonant frequency, respectively. The unloaded Q of the odd mode resonance is higher than the unloaded Q of the CRLH-TL resonator because of coupling between two single resonators. The simulation is accomplished with the Ansoft designer. The simulation results agree well with the theoretical analysis.
