Microwave dielectric properties of MgB_2O_6 (B^<5+> = Nb, Ta, Sb) and their solid solutions have been investigated to control the temperature coefficient of resonant frequency (TCF) of MgTa_2O_6 ceramics. At the composition range of single phase, TCF of the sintered specimens was depended on the distortion of oxygen octahedra by the substitution of Nb and/or Sb for Ta of MgTa_2O_6. For the Mg(Ta_<1-x>Nb_x)_2O_6 (0.2 ≤ x ≤ 0.8) and Mg(Ta_<1-x>Sb_x)2O6 (0.1 ≤ x &le: 0.4) sintered specimens, the quality factor (Qf) was decreased with x content. The dielectric constant (K) of the sintered specimens was dependent on the dielectric polarizabilities.
