Sensitivity analysis of different resonator structure for sensor applications in microwave region

In this study, double sided electric-LC resonator (DELC) and double sided asymmetric electric-LC resonator (DAELC), which is designed to improve the mutual capacitance in the DELC, have been proposed as an alternative to double sided split ring resonator (DSRR) whose usage is available in sensor applications in literature. For the performance analyses of the proposed structures, the sensitivity of the resonance frequency to the interlayer dielectric constant is investigated numerically by CST Microwave Studio (MWS). In the analyses, interlayer dielectric constant is changed between 1 and 5. Among the studied three structures, DAELC demonstrates that it may be a good alternative to the already proposed DSRR structure by presenting highest sensitivity to the dielectric constant changes with 20.107%.
