Main Trends in the Development of Microwave Dielectric Materials for Cellular Communication Devices: A Review

The requirements for high-quality microwave (MW) dielectrics, which are used in the development of cellular communication devices (radio filters, solid-state generators, etc.) for the transition from 3G to 5G communication, are considered. The results of studies on important classes of MW dielectrics based on complex oxide systems of different crystal structures, such as potassium tungsten bronze, perovskite, pucherite, dreyerite, scheelite, as well as high-quality MW dielectrics with different permittivities, are systematized.
