“…Reducing the perturbation even further gives a linear response and only two calibration media are now required (air and water for which the dielectric permittivity is well known). For demonstration purposes we will use a one port coupled ring resonator as shown in figure 13 (Saeed, 2007). The resonator is modelled as an equivalent RLC network where R is the resistance, L is the inductance and C is the capacitance.…”

“…The solution proposed in [5] has addressed the complexity of creating vias by replacing them with metalized channels on the boundary walls however, these structures have low unloaded quality factor of about 58. Material characterization through microstrip resonator has been reported in [6], [7], the techniques proposed are planar and require small quantity of liquids but they are less sensitive and have low quality factor. Researchers have also proposed measurement cells based on open Whispering Gallery Mode (WGM) Dielectric Resonators (DR).…”

“…The resonant techniques in [2]- [4] rely on measuring the relative shift of the magnitude of S-parameters due to the material-under-test (MUT). This method has inherent limitations when materials with high dielectric loss at microwave frequencies (such as organic liquids) need to be characterized.…”

-In this paper, planar microwave oscillators are used to measure the dielectric constant of organic liquids for the first time. Dielectric constant of an unknown material is calculated based on the change in oscillation frequency caused by the material-under-test (MUT). A split-ring resonator (SRR) is chosen as the sensing element due its small area and high confinement of electric fields which makes it sensitive to permittivity changes of the MUT above the SRR. A C-band microwave oscillator prototype is fabricated on RT/Duroid 5880 substrate and calibrated using ethanol and methanol as reference materials. The dielectric constant of small quantities (< 20μL) of acetic acid, xylene, isobutanol and ethyl acetate are extracted from measurement of oscillation frequency shift and show good agreement with previously reported values.Index Terms -Permittivity measurement, microwave oscillator, split-ring resonator.
