Abstract

High-dielectric-constant and low-loss ceramics in the Zn(Ta_0.95Nb_0.05)₂O₆ ceramics have been prepared by the conventional mixed-oxide route and their crystal structures and microwave dielectric properties have been investigated. The forming of solid solution Zn(Ta_0.95Nb_0.05)₂O₆ was confirmed by the XRD patterns, the EDX analysis and the measured lattice parameters. The dielectric properties exhibited a significant dependence on the sintering condition and crystal structure of the ceramics. A fine combination of microwave dielectric properties IS achieved in the Zn(Ta_0.95Nb_0.05)₂O₆ ceramics sintered at 1325°C for 2 h with ε_r of 39.33, Q×_f of 86,000 GHz (where f = 7.57 GHz, is the resonant frequency), and f t value of 10.6 ppm/°C. It is proposed as a suitable candidate material for small-sized GPS patch antennas.
