Microwave dielectric properties of (1 − x)(Mg0.95Co0.05)TiO3-x(Na0.5La0.5)TiO3 ceramic system
چکیده انگلیسی
The microstructures and the microwave dielectric properties of the (1 − x)(Mg0.95Co0.05)TiO3-x(Na0.5La0.5)TiO3 ceramic system were investigated. Two-phase system was confirmed by the XRD patterns and the EDX analysis. A co-existed second phase (Mg0.95Co0.05)Ti2O5 was also detected. The microwave dielectric properties are strongly related to the density and the matrix of the specimen. A new microwave dielectric material 0.88(Mg0.95Co0.05)TiO3-0.12(Na0.5La0.5)TiO3, possessing an excellent combination of dielectric properties: εr ∼ 22.36, Q × f ∼ 110,000 GHz (at 9 GHz), τf ∼ 2.9 ppm/°C), is proposed as a candidate dielectric for GPS patch antennas.
