Abstract
An instrument and process for measuring moisture content of an article. A microstrip resonator receives a signal from a microwave sweep oscillator. A holder holds the article wherein the article under test is placed over a substrate of the resonator and covers the resonator and provides orientation to the article under test in a desired direction to the sample. A detector receives transmitted as well as reflected signals from a resonator sensor for measurement of Q factor and frequency shift of the resonator. The moisture content of the article is determined by the change in effective permittivity of a cross-section of the miscorstrip.
