Abstract

This paper presents high-sensitivity sensors based on an open complementary square split-ring resonator and a modified open complementary split-ring resonator operating at 4.5 GHz and 3.4 GHz, respectively. The sensors are designed for the detection of multiple liquid materials, including distilled water, methanol, and ethanol. The liquid under test is filled in a glass container loaded using a pipette. Compared to the conventional OCSSRR, the modified OCSSRR with multiple rings exhibits a higher frequency shift of 1200 MHz, 1270 MHz, and 1520 MHz for ethanol, methanol, and distilled water, respectively. The modified sensor also demonstrates a high sensitivity of 308 MHz/RIU for ethanol concentration which is the highest among the existing microwave sensors. The sensors in this manuscript are suitable for multiple liquid-material-sensing applications.

摘要

本文介绍了基于开放式互补方型分裂环谐振器和改进型开放式互补分裂环谐振器的高灵敏度传感器，它们分别工作在4.5GHz和3.4GHz。这些传感器设计用于检测多种液体材料，包括蒸馏水、甲醇和乙醇。被测液体用移液器装入玻璃容器中。与传统的开放式互补方型分裂环谐振器相比，具有多个环的改进型开放式互补分裂环谐振器对乙醇、甲醇和蒸馏水分别表现出更高的频率偏移，分别为1200MHz、1270MHz和1520MHz。改进后的传感器对乙醇浓度还表现出308MHz/RIU的高灵敏度，这在现有的微波传感器中是最高的。本文中的传感器适用于多种液体材料传感应用。
