Abstract
A high temperature open resonator measuring system for low loss radome materials is introduced. The scalar network analyzer measures the open resonator with sweeping frequency method under the control of a computer. After getting the resonance frequency and Q factor of the vacant and loaded cavity, the system works out the dielectric parameters and loss tangent of the material being tested. The dielectric is heated up by the temperature controller with a highest temperature more than 1000°C. The test results of teflon by this system are close to the data in the literatures and the measurements of a kind of low loss radome material are also quite satisfactory.
