This study examined the potential applications of microwave dielectric properties of La (1‐2x/3) Ba x (Mg 0.5 Sn 0.5 )O 3 ceramics in rectenna. The La (1‐2x/3) Ba x (Mg 0.5 Sn 0.5 )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 La 2.98/3 Ba 0.01 (Mg 0.5 Sn 0.5 )O 3 ceramics that were sintered at 1550 °C for 4 h.
