Abstract :
The implementation of a low-cost driving electronics for a permittivity measurement system employing resonant microwave sensors is presented in this paper The complete driving electronics needed to perform scalar measurements is described; and its components are illustrated and characterized. The measurement results and accuracy have been compared with commercial devices, showing similar performances
