Abstract :
A new method for determining the moisture content of dielectric material is proposed. The sample, placed on a circular patch antenna, modifies the resonant frequencies; measuring these variations enables the dielectric permittivity and the moisture content to be determined by using the Bottcher model or the molecular model
