Resumen

This project is focused on the characterization of an electromagnetic sensor made from a substrate-integrated waveguide resonator to several glucose concentrations in liquid samples. The aim is to determine the suitability of this system to be used as a glucose sensor. The characterization process was carried out by performing multiple frequency sweep tests on the sensor and evaluating the variations in its response, and the displacement in the resonant frequency. The resulting data was analyzed and compared to identify trends and patterns that could lead to a parameter to standardize the response. It was found that the presence of increasing concentrations of glucose causes a decrease in the attenuation of the signal and a displacement of the resonant frequency (and the rejection band) towards lower frequencies. Additional analysis demonstrated that though there is an evident trend, the available data requires further analysis to determine a strict pattern that could be used to establish a rule for the behavior of the sensor in the presence of glucose.
