I. Gagnadre et al., CIRCULAR PATCH ANTENNA SENSOR FOR MOISTURE-CONTENT MEASUREMENT ON DIELECTRIC MATERIAL, Electronics Letters, 31(14), 1995, pp. 1167-1168
A new method for determining the moisture content of dielectric materi
al is proposed. The sample, placed on a circular patch antenna, modifi
es the resonant frequencies; measuring these variations enables the di
electric permittivity and the moisture content to be determined by usi
ng the Bottcher model or the molecular model.
