DESIGN, DEVELOPMENT AND EXPERIMENTAL ANALYSIS OF VERTICALLY STACKED MICROSTRIP
RING RESONATOR
Abstract:
To Design and develop a stacked ring resonator (SRR) with high Q-factor for two port measurement of vertically stacked ring
resonator. To perform experimental evaluation of stacked ring resonator with respect to simulated results.
High frequency electromagnetic wave simulation is synthesized by using high-frequency modeling software. High Frequency
Simulation Software is utilized for fine tuning the 3D model of stacked ring resonator designed to achieve high Q-factor and low loss.
Optimized design values are implemented to fabricate vertically stacked microstrip ring resonator. Vector Network Analyzer (VNA-
Agilent 8714ET) is used to verify the results of the fabricated design.
Sensitivity analysis of fabricated resonator is done against various sample size and for different petroleum liquids.
Measurement of real and imaginary part of permittivity is verified with previously published data.
A microwave resonator sensor is successfully developed to achieve electrical characterization of petrol and adulteration
measurement of petrol with ethanol and diesel.
Features:
1) Non-destructive method
of finding impurity
percentage
2) Simple and handy
instrument
3) Requires only ISM band
(frequencies)
4) Less sample quantity
Graph:
1] Improvement in Q-factor when stacked 2] Variation in Q-factor for various impurity level
Conclusion:
The proposed design shows great potential for measurement of real and imaginary part of dielectric material of petroleum liquid.
Analyzing gasoline as a sample for complex permittivity by the proposed method is highly efficient in terms of cost, computation
time and sample size. As Q-factor of stacked ring resonator is more. This results in greater accuracy in measuring adulterations in a
given volume of sample petrol.
