Abstract :
Complex permittivity is one of the most important parameters of microwave dielectrics. When the dielectrics work in high temperature environments, the complex permittivity as a function of temperature should be measured while designing dielectrics and applying in microwave devices or radome. A test cavity used at temperature up to 1500degC is designed and fabricated, and the test system for complex permittivity measurement at high temperatures is also built. Some typical samples are measured.
