The (Nd, Sm, Yb) (Ti0.5Mo0.5) O4 ceramic compounds were prepared via conventional solid state reaction method and observed
to crystallize in the tetragonal scheelite structure with I41/a space group. Structural analysis of these compounds was carried
out using Rietveld refinement and studied the nature of bonding (bond length, bond valences of ions) with substitution of
different rare earth (Nd, Sm and Yb) ions. Microwave dielectric properties such as dielectric constant (εr), quality factor (Q×f) and
temperature coefficient of resonant frequency (τf) were calculated using Agilent Vector network analyzer. The dielectric constant of
these compositions was correlated with polarizability of compositions. The quality factor and f were explained with the structural
characteristics. All these compositions observed to possess more than 93% theoretical density and have good microwave dielectric
properties such as (εr= 8 –12, Q f = 27000 – 35000 GHz and τf = -40 to -60 ppm/oC).
