Summary:
With the demand for quality control of exporting agricultural products, microwave sensors have been developed. For instance, a coupled-dipole sensor has been developed for moisture content measurement of paddy [1]. Both reflected and coupled signals were measured. A switched polarization coupled-dipole sensor was proposed to measure only coupled signal [2]. For fruit, a coupled-patch sensor was proposed for durian maturity stage inspection [3]. These works relied on electromagnetic simulators which require long computation time. The closed-form formulations need long time for derivation, but less time for calculation. In addition, physical insight how it works is provided. Therefore, this article presents the principle of a coupled-antenna for sensing quality of agricultural products. Calculation results are illustrated and validated by experiments which ensure the correct of the calculation. It is useful for developing a sensor for agricultural product inspection.
