A miniaturized U-shape patch sensor (15 mm × 15 mm) was designed at dual resonating frequencies (f r) 5.2 GHz and 6.8 GHz. The proposed design printed on FR4 material with a thickness of 1.676 mm and relative permittivity 4.4. To simulate the performances of the proposed design, the CST Microwave Studio (CST MWS) was used. The reflection coefficient of U-shape patch sensor was measured. Basmati rice was investigated, and bulk density was increased with increase of moisture content, hence varied from 554.3 to 591 kg/m 3. It has the longest average rice length (L) 7.2 mm, average width (W) 1.61 mm, and L/W ratio 4.47. The percentage of moisture was varied from 10.71% to 21.87% calculated on a wet weight basis. The lowest mean relative error (MRE) determined between predicted moisture content (PMC) and actual moisture content (AMC) was 0.55% at dual frequencies.

Abstract-In this paper, full-wave analysis of a microstrip-ring resonator capacitively coupled to Microstrip transmission line is presented. The method of the analysis is based on spectral domain in rectangular coordinate system. Since this coordinate system is not compatible with ring structure, triangular basis functions have been utilized for the current distributions on the ring surface. Applying Galerkin's method in spectral domain, the resonant frequencies of the structure and current distributions on the conductors are calculated and the effects of various parameters are studied. To verify the method of analysis, our results are compared with others and the accuracy of the method has been confirmed.

A microstrip ring resonator (MRR) is perturbed by overlaying mug grains (Phaseolus Radiatus Linn.), having different moisture contents (7–42%), at eight different angles. Out of the two orthogonal degenerate modes (even and odd) of MRR, only the even mode is sensitive to the strength of perturbation (grain moisture). The overlay angle and moisture‐dependent perturbation factor is reported. The results are compared with the reported perturbation results of Yogi et al. [16]. © 2002 Wiley Periodicals, Inc.
