Abstract: This paper presents a microwave sensor for the non-destructive dielectric
characterization of biological tissues. The proposed sensor is based on
microstrip ring-resonator, which is utilized for quality evaluation of meat
at 1 GHz frequency. The obtained results from measurement and simulation are
in good agreement for the studied meat samples. Using numerical
formulations, dielectric constant of meat samples is extracted and then
compared with those acquired by well-established and commercially available
coaxial-probe method. Negligible difference is observed in obtained data,
the maximum discrepancy is about 6% only. Findings of this study provide
new possibilities to employ microwave circuits for non-destructive
evaluation of dielectric materials.
