Abstract
High-dielectric-constant and low-loss ceramics in the Zn(Ta0.95Nb0.05)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(Ta0.95Nb0.05)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(Ta0.95Nb0.05)2O6 ceramics sintered at 1325°C for 2 h with εr 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.
