Microwave dielectric ceramic with high dielectric constant and low loss and preparation method thereof
The invention provides microwave dielectric ceramic with a high dielectric constant and low loss. The dielectric constant of the microwave dielectric ceramic is 78-80, the Q * f value of the microwave dielectric ceramic is 13900-15200 GHz, and the temperature coefficient of resonance frequency of the microwave dielectric ceramic is -5 ppm/DEG C to +5 ppm/DEG C. The Q * f value of the microwave dielectric ceramic is improved while a relatively high dielectric constant and a near-zero resonant frequency temperature coefficient are maintained, and collaborative improvement of dielectric performance indexes is realized.
