Abstract: “Split ring resonator is area of major research in recent years especially in the field of fluid sensing, because of their ease in fabrication and moderate quality factor and resonant frequencies. Split ring resonator provide shift in resonant frequency after system is perturbed by introducing a small amount of fluid into the system. In this paper a simulation based sensitivity analysis has been carried out to choose a split ring resonator which can provide maximum shift in resonant frequency when a sample mixture of polar liquids perturbs the system. Simulation results show effect of length of split ring resonator and orientation of micro-capillary tube on resonant frequency and quality factor. A comparison has been presented on obtained results.”
