Abstract :
In this paper, a hemispherical open resonator is used to measure the quality factor and resonant frequency of various materials in the millimeter wave band. This measurement method allows us to determine the permittivity and the loss tangent of homogeneous materials. Materials like PTFE, PE and PS were used to validate the measurement system. Finally, we measured the resonant frequency and quality factor of samples of Rogers RO4003C and TMM10, which are up to now only characterized up to 10 GHz.
