With the rapidly development of 5G and 6G technologies, developing ceramics with a moderate dielectric constant, a high quality factor, and a resonant frequency temperature coefficient close to 0 becomes a research hotspot. A novel series of microwave dielectric ceramics Ca0.95-xCu0.05(Na0.5Bi0.5)xMoO4 were synthesized by a solid-state reaction method. The influences of sintering temperature and component change on the microwave dielectric properties were investigated. The ceramic property was analyzed by X-ray diffraction, Raman spectroscopy, and scanning electron microscopy. The results show that the εr of Ca0.45Cu0.05(Na0.5Bi0.5)0.5MoO4 ceramic with NB content of 0.5 sintered at 640 ℃ is 15.8, Qf is 21 361 GHz, and τf is 3.8×10-6/℃. Also, Ca0.45Cu0.05(Na0.5Bi0.5)0.5MoO4 ceramic is compatible with Al electrode, indicating that Ca0.95-xCu0.05(Na0.5Bi0.5)xMoO4 ceramic has a great potential application as a low-temperature co-fired ceramic material.
