AIM To study the reliability of complex permittivity measurement system at 2450 MHz. METHODS The complex permittivity of low loss and high loss dielectric materials were measured separately, and compared with nominal value, to check up the reliability and repeatability of the measuring results. RESULTS The measuring accuracy of low loss and high loss dielectric materials was high, and measuring errors were low. CONCLUSION This measurement system will be able to measure complex permittivity of dielectric materials at 2450 MHz accurately.
