Abstract :
This work shows a low cost system for dielectric permittivity sensor in the microwave frequency range. All components of system are described. With this system, the real part of permittivity of low loss dielectrics can be obtained. It provides the same results that a Vector Network Analyzer (VNA). The permittivities of Teflon, wood, paper, white and yellow corn and sorghum are obtained.
