Multiple-Pole CSRR-based Microwave Sensor for Glucose Levels Detection

Résumé

In this paper, we propose a microwave biosensor that comprises a rectangular plexiglass channel integrated on a triple-pole complementary split ring resonator (TP-CSRR) structure. The sensor operates in the centimeter-band 1 – 6 GHz and is fabricated on top of a thin FR4 dielectric substrate. The sensor element is excited via a coupled microstrip transmission-line etched on the bottom side of the substrate. The proposed CSRR-based sensor is used as a near-field probe to noninvasively monitor the changes in glucose concentrations in the blood mimicking fluid by tracking the amplitude variations of the harmonic transmission resonances at various concentrations. The fluids are loaded inside a channel representing roughly a blood vessel. The proposed sensor is shown to exhibit higher sensitivity performance compared to the conventional single-pole and other similar sensors in the literature. The sensitivity, reliability and repeatability of the proposed sensor are demonstrated by the in-lab measurements using a Vector Network Analyzer (VNA).
