  ABSTRACT: In this paper measurement of real part of permittivity and loss tangent of (1-x) Zn.xMg.TiO3 (ZMT) material in powder form in S-band of microwave frequencies is presented and the associated accuracy estimated. This approach is based on the measurement of transmitted power from the cavity at and off resonance. Details of the design and fabrication of the rectangular cavity and the input and output coupling are given. The variation of dielectric properties of (1-x) Zn.xMg.TiO3 (ZMT) with x-value and calcination temperature (for x = 0.1) is presented. The effect of doping of V2O5 is also studied. The results of present work may provide useful design guidelines for development of microwave compo-nents including dielectric resonator antennas.
