Abstract

Two Fabry-Perot open resonators are designed and constructed in order to measure the dielectric properties with low loss dielectric materials in the Ka-band (26-40 GHz), V-band (50-75 GHz) and W-band (75-110 GHz) frequency bands. A 3-D finite element electromagnetic code is used to simulate the TEM00q mode in the open resonator. Measurements are made by both length variation method and frequency variation method. The measured permittivity and loss tangent of BeO (995) are 6.7 and 7e-4, respectively. Permittivity and loss tangent of CVD diamonds are also measured in the V-band and W-band. Measurement results on BeO995, Teflon, and CVD diamonds are presented.
