摘要:
This study examined the potential applications of microwave dielectric properties of La(1-2x/3)Bax(Mg0.5Sn0.5)O-3 ceramics in rectenna. The La(1-2x/3)Bax(Mg0.5Sn0.5)O-3 ceramics were prepared by the conventional solid-state method with various sintering temperatures. An apparent density of 6.62 g/cm(3), a dielectric constant of 20.3, a quality factor of 51,700 GHz, and a temperature coefficient of resonant frequency of -78.2 ppm/K were obtained for La2.98/3Ba0.01(Mg0.5Sn0.5)O-3 ceramics that were sintered at 1550 degrees C for 4 h.
