Dielectric Properties and Microstrip Patch Antenna Performances of 0.95MgTiO₃-0.05CaTiO₃ Microwave Ceramics

Abstract:

τMicrowave dielectric properties of 0.95MgTiO₃-0.05CaTiO₃ ceramics and their performances as H-shaped microstrip patch antenna were investigated. Best values of dielectric constant (ε_r) and quality factor (Q×f) of 19.00 and 66800GHz, respectively, were obtained for the microwave ceramics sintered at 1300°C for 3h. A near-zero temperature coefficient of resonant frequency (τ_f) of -4.7ppm/°C was obtained for the ceramics with sintering 1280°C for 3h. A new kind of H-shaped microstrip patch antenna with two resonant frequencies was fabricated by using of this kind of ceramics as antenna substrate. The return loss bandwidth of the patch antenna was extended with the increasing of substrate thickness at both resonant frequencies of the antennas, around 1.530GHz and 2.750GHz, respectively.
