Abstract

In this paper, we present a high quality (Q)-factor resonator utilizing biocompatible materials, thin glass and polydimethylsiloxane, at microwave regime. The proposed resonator is completely matched with a 50-ohm characteristic impedance via the materials. From the resulting matching, we find that it shows a half-wavelength resonance having an extremely high quality-value. Actually, the loaded quality-factor is about 1 670 at the resonant frequency of 12.52 GHz. From this work, we suggest that our device can be a good candidate as a simple, cost-efficient, and non-contact sensor device based on frequency and quality-factor variation.
