Abstract

The Most of affordable daily glucose monitoring techniques in diabetic patients are invasive requiring sample of blood. Microwave sensor can nondestructively measure parameter inside volume. This property suggests that microwave sensor would be well suited for noninvasively measuring blood glucose concentration in human being. After fabricating microwave based noninvasive sensor, at primary stage this sensor is tested with aqueous glucose. A Planar Microstrip Ring Resonator is designed, simulated and implemented to resonate at 1 GHz. Dielectric material is placed above a Microstrip ring resonator. Because of this near field of resonator gets interact with a Material Under Test (MUT) and electrical characteristics of resonator change in relation to the permittivity of the material. Change in the dielectric causes corresponding shift in resonating frequency of Microstrip Patch Antenna. This relationship can be useful to measure Blood Glucose Concentration level. Vector Network Analyzer is used to measure the shift in resonating frequency. The design procedure is described here and experimental results are reported.

用平面环形谐振器测量葡萄糖水溶液的介电特性

大多数负担得起的糖尿病患者每日血糖监测技术是侵入性的，需要采集血液样本。微波传感器可以无损地测量体积内部参数。这一特性表明微波传感器非常适合于无创测量人体血糖浓度。在研制出微波无创传感器后，对该传感器进行了初步的葡萄糖测试。设计、仿真并实现了1 GHz频率的平面微带环形谐振器。介电材料置于微带环形谐振器之上。由于谐振器的近场与被测材料相互作用，谐振器的电特性随材料介电常数的变化而变化。介质的变化引起微带贴片天线谐振频率的相应变化。此关系可用于测定血糖浓度水平。矢量网络分析仪用于测量谐振频率的位移。本文介绍了设计过程，并给出了实验结果。
