Abstract:
This paper presents a novel method for determining the moisture content in spices by means of compact microstrip fractal resonator. The proposed resonator is designed at 1 GHz using FR4 substrate with dielectric constant of 4.6. A resonator sensor in the shape of fractal designed using the tool ADS and working at 0.9 GHz to 3 GHz band is demonstrated. The relative shift in frequency and attenuation was observed to vary with respect to the moisture content/permittivity of the test material independent of its density.

Key words:  Attenuation, microstrip sensor, minkowski resonator, moisture content, permittivity, shift in frequency,
