Abstract

A forced-mode composite resonator is used on a moisture sensor to characterize humidity percent of honey at the microwave regime. Sensors of two different shapes, one rectangular and one circular, are designed and fabricated using commercial phenolic sheets. The resulting resonant frequency of the sensor changes as a function of the humidity contained in the sample. Honey samples are placed inside small glass bottles and this foreign material is taken into consideration. Measurement results are as expected and when the effective permittivity value of the samples is too high the modes will interchange.
