“…For small change in permittivity of the sample, change in center frequency is considerably more for vertically stacked ring resonator. Higher the sensitivity more is the accuracy in measurement because even a small change in real part of permittivity can easily be measured [14] [11]. Petrol sample collected from Shell Petroleum, Pune.…”

A new microwave resonator technique of permittivity measurement of a liquid sample is proposed. The technique is based on the use of a Vertically Stacked Ring Resonator filled with dielectric in between them. The proposed design will improve the sensitivity of single ring resonator in terms of Q-factor and in turn increase the measuring sensitivity. Experimental data is testified against the related theory and compared with the results obtained by other researchers. Full wave simulation Software Ansoft HFSS 11 is used for optimization of the resonator. The measurement with this system indicates high potential for development of portable technique for liquid petroleum quality analysis.

The concept of dielectric constant measurement has been extended and applied in agriculture, pharmaceutical and food industry for quality control of liquids. Dielectric analysis of material at microwave frequencies can be done using novel shielded stacked multi-ring resonator (SMRR). The dielectric constant of liquids and paste has been calculated using SMRR with greater accuracy than the planar resonator, boxed resonator and stacked resonator. SMRR contains a ring resonator with fed patch and parasitic patch with different numbers and sizes of rings. The dimensions of rings on the parasitic patch are optimized to achieve Quality factor Q greater than 100 and return loss less than-2 dB. Due to dual resonance in novel SMRR, structure losses are reduced by 50% than planar resonator structure. The behavior of SMRR structure at the 2.45 GHz frequency is studied with E field and H field. 3D model is designed in Computer Simulation Technology Microwave Studio (CST MWS) using TLM (Transmission Line Modeling) solver. Electromagnetic field analysis as well as impedance bandwidth of SMRR using CST MWS 3D model prove that electromagnetic coupling in SMRR structure increases thus improves quality factor. In SMRR quality factor increases and losses reduce help us to predict the complex permittivity of material for quality analysis.

“…The monitoring of hydrocarbon quality is an important goal, not only for modern automotive, industrial and aerospace applications, but also in view of the next uses of biodiesel fuel generation [1,2]. There are many different contaminants that can compromise hydrocarbon quality, such as alcohol, water, ethanol, and oils [3][4][5]. Monitoring should be fast, accurate and real time, because these contaminants could alter the lubrification properties of fuel and reduce motor performance.…”

“…In general, traditional laboratory techniques, such as an evaporation test, distillation, gas chromatography, etc., useful to identify the quality of petroleum liquid and its derivative products, are more expensive and introduce a delay time for analysis. Microwave sensor techniques provide an interesting alternative approach [5][6][7][8][9][10][11].…”

Substrate-Integrated Waveguide Microwave Sensor for Water-in-Diesel Fuel Applications

et al. 2021

View full text Add to dashboard Cite

A water-in-diesel microwave sensor based on a substrate integrated waveguide (SIW) microwave applicator is designed and characterized in this study. The interaction between the microwave electromagnetic field and the diesel fuel contaminated with small concentrations of water is obtained via suitable radiating slots placed on the top of an SIW waveguiding structure. The SIW applicator working frequency is chosen by observing the behavior of the complex dielectric permittivity of the fuel–water blend based on a preliminary wide band investigation. The performances of the SIW microwave sensor are evaluated in terms of scattering parameter modulus |S21| as a function of the water concentration in ppm. The best sensitivity Δ|S21|Δρ=1.42 mdB/ppm is obtained at a frequency of f=9.76 GHz, with a coefficient of determination R2=0.94. The sensor is low-cost, low profile and ensures a good sensitivity for constant and real-time monitoring.
