Description 134-138
The value of loss tangent (tanδ) of the low loss material is of the order of 10⁻⁴. There are different methods used to measure loss tangent as well as complex permittivity. Out of different methods, Cavity Resonator method is the best method for the measurement of complex permittivity of low loss materials i.e. teflon, duroid, polystyrene and stycast. In this present paper, a cylindrical cavity resonator is designed and fabricated in the frequency range 2.2-2.3 GHz and the complex permittivity of low loss material teflon using cavity resonator method has been measured.
