Research progress of low permittivity microwave dielectric ceramics

In recent years, the microwave frequency used in communication technology has become higher and higher, the amount of information transmitted is also increasing and the required transmission speed and quality have become higher and higher. So low permittivity microwave dielectric ceramics, with low loss, high quality factor, and temperature coefficient of resonance frequency close to zero, is demanded to realize the advanced microwave communications. In this paper, the typical research system of low permittivity microwave dielectric ceramics are divided into different categories to be introduced. Finally, the research and development of various types of low permittivity microwave dielectric ceramics are summarized.
