Theoretical Analysis Of Composite Right/Left-Handed Coupled Transmission Line Resonators

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 approach. 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.
