In this study, we prepared (1 − x)Bi12CeO20–xBiFeO3 ceramics using conventional solid-state methods with various material compositions and sintering temperatures. X-ray diffraction and scanning electron microscopy were employed to analyze the composition of the ceramic microstructures. In experiments, as x increased, the dielectric constant and τf value increased, and the Q × f value decreased. We also investigated the correlation between the relative proportions of two ceramic substances and their microwave dielectric properties. The Bi12CeO20–BiFeO3 ceramic system is suitable for use as a substrate in low-temperature cofired ceramic antenna temperature sensors.
