摘要

This paper presents properties of a dielectric ring resonator and its application to measurement of material moisture. Theoretical analysis has been done to select better resonant modes in the resonator with higher sensitivity and wider moisture content measurable range than the formerly often used TE_(011) mode by some researchers. Experiments have also been done to verify the theoretical results. The HE_(212) mode in the resonator has the highest sensitivity of 1.0 MHz frequency shift corresponding to change of 1.0% moisture content. The measurable range of moisture content is up to 12% at dry basis. The mode of HE_(211), has a wide measurable range approximately between 3% and 75% and its corresponding frequency shift is 12 MHz.
