Comparative Analysis of Tunable Dual Split Ring Resonator in Different Dimensional Configurations

Abstract

A simulation based analysis has been carried out to find most appropriate and practical configuration of SSRs; Dual broadside coupled split ring resonators to provide a considerable shift in resonant frequency. This configuration has been optimized keeping in view the shift in resonant frequency and quality factor. Most suitable parameters have been found which provide maximum shift in resonant frequency and minimum variance in quality factor. An analytical solution has been proposed based on capacitor-inductor resonant network analogy to approximate the resonant frequency. Expressions for calculation of overall capacitance of dual split rings have been developed. Finally, calculated resonant frequencies from developed analytical solution have been compared with the simulated results.
