Abstract
In this work, we investigate the impact of the sample container’s geometry on the parameters of a low-cost, single-use microwave sensor designed for honey adulteration detection. The sensor features a nine-finger circular Interdigital Capacitor (IDC) geometry, which provides a multi-resonant response allowing for sensitive dielectric spectroscopy. The analysis focuses on the 1 to 2 GHz frequency band, due to the optimal penetration of the electromagnetic field into the sample in that range. To isolate geometric effects from substrate variability, a parametric study of sixteen 3D-printed container configurations was conducted using a single sensor unit loaded with off-the-shelf lime honey. Experimental results demonstrate that the sensor’s response saturates at a sample height of approximately 5 mm, indicating full field containment. Furthermore, increasing the radius enhances performance, though this comes at the expense of a larger sample volume. Different behavior was observed between resonant modes at 1.19 GHz and 1.49 GHz, attributed to the trade-off between volumetric field penetration and dielectric losses. The results suggest that a thin dielectric floor can be introduced without performance degradation, paving the way for the cost-effectiveness of a design improvement, with a reusable sensor and disposable sample containers.
