Broadband Millimeter Wave Dielectric Properties Measurement of Low Loss Materials

This paper designed a dielectric property test system of ultra wideband millimeter wave (UWB) materials by using quasi optical resonator method. By changing some structures, the dielectric property test of low loss materials in 12∼170GHz frequency band can be realized This paper breaks through the point frequency test method of low loss materials, and make it possible for broadband approximate frequency sweep test by using multi-point continuous test. Then test the common dielectric material quartz and automotive radar electronic materials at point frequency of 77GH. The test system has the characteristics of wide test frequency band, high precision and frequency sweep test.
