Topic Be able to measure the permittivity of the dielectric material with high frequency with form of the transmission line which is really used, the permittivity which at the same time includes frequency characteristic, permittivity measuring method of the material which can calculate tan from high accuracy is offered.SolutionsElectric quality per unit length which formed the transmission line which signal conductor consists of with 3 and ground conductor 4 prepares unknown measurement jig 1 in dielectric baseplate, 2 signal conductor shorting with 3 and ground conductor 4 in at least 4 places of length direction of the transmission line, measures reflection coefficient S11 From measurable quantity in short circuit state quality of the transmission line (degree of transmission and initial phase ) it seeks in the calculation, furthermore from quality of the transmission line and physical size of the transmission line calculates permittivity and tan of the transmission line material in the calculation.
