| Summary: | This study proposes the design of a dual-band
independent microwave sensor for the simultaneous detection of
the permittivity of various solid materials. The sensor utilizes
two U-shaped resonators that are connected by a microstrip feed
line with an impedance of 50 Ω. The 1st resonator operates at a
frequency of 1.21 GHz and the 2nd resonator operates at 2.1
GHz. The independence of the resonators was determined using
Pearson correlation analysis in a scenario where the Materials
Under Test (MUT) were placed in the sensing hotspot area of
both resonators. Results indicated a low correlation coefficient
(r < 0.2) between the resonant frequencies of the two resonators
when the MUT was placed in both resonators simultaneously,
with X2 = 0.01 and Y1 = 0.076. This proposed sensor design has
the potential to be a valuable solution for the simultaneous
detection of different permittivity of solid materials with high
accuracy in various fields such as the food industry, biomedical
applications, and material quality control in the pharmaceutical
industry. |
