Dielectric Properties Measurement Using Ring Resonator

Amruta Kulkarni, Vidya Deshmukh

Abstract: This paper gives an idea of determining electrical properties of a material using simple ring resonator. Here, the radiating element is a ring resonator. The ring resonator with sufficient coupling gap is designed and simulated in HFSS software and observed S parameters. After designing a ring resonator, the layer of aqueous glucose with different known dielectric constants is deposited on the ring covering coupling gap and again analyzed and finally observed the shift in resonant frequency. The simulation result shows that, the resonant response of the sensor changes as per the change in permittivity of aqueous glucose.

Keywords: ring resonator, insertion loss S21, coupling gap, dielectric constant
