A New Measuring Method of the Relatively Permittivity Based on Antenna's Resonant Characteristics

Abstract:

This paper proposes a matter of permittivity measurement method which based on the microwave antennas resonant characteristics. The basic principle of measuring permittivity was analyzed by the antenna resonance theory. The simulation model has been build and analyzed by Ansoft HFSS simulation software. The relationship between different permittivity and the antennas resonant frequency was given. The experimental model was designed and the experimental data of sample was measured. The experimental and simulation data are compared and discussed. Results show that the simulation and experimental results are consistent well; the antenna resonance method to measure the permittivity is feasible.
