Submersible Microwave Sensor for Heated Oil Characterization Using Complementary Multiple Split-Ring Resonator

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

In this paper, we present a submersible microwave sensor with significantly improved sensitivity for heated peanut oil determination. The structure consists of two complementary multiple split-ring resonators (CMSRRs) loaded in an open-ended flared microstrip patch. By using High Frequency Simulator Structure (HFSS), the designed sensor is simulated and optimized. The designed device is fabricated on a Rogers RT/Duroid 5880 substrate, and operate at 8.49 GHz. When the sensor is immersed in heated peanut oils to be tested, we can find that the resonance and peak attenuation of the proposed sensor change remarkably. The experimentally measured sensitivity is up to 7.25%.
