Abstract A multi spiral split ring resonator based sensor is proposed for the characterization of the dielectric properties of a water ethanol mixture. The use of a narrowed microstrip line to excite the multi spiral resonator allows enhancement of excitation current and increase the sensitivity of the sensing area. Good agreement will be presented between theoretical and measured electrical parameters of the resonator in a wide frequency range from 2 to 5 GHz. The proposed sensor shows high sensitivity, miniature size, and affordable cost and above all laboratory-on-chip compatibility important for a large-scale production.

用于水乙醇混合物表征的微带耦合高灵敏度传感器

摘要 提出了一种基于多螺旋裂环谐振器的传感器来表征水乙醇混合物的介电特性。使用窄的微带线来激励多螺旋谐振器可以增强激励电流并增加感测区域的灵敏度。在 2 至 5 GHz 的宽频率范围内，谐振器的理论电气参数和实测电气参数之间将呈现出良好的一致性。所提出的传感器显示出高灵敏度、微型尺寸和可承受的成本，最重要的是对大规模生产很重要的芯片实验室兼容性。
