The technology in modern mobile communication, wireless local area networks and global position system for mobile communication has been innovated rapidly, which asks the microwave electronic components based on microwave dielectric ceramics to have better performances. In recent years, microwave dielectric ceramic components with the characteristics of miniature, high frequency, chip level, module form and the related dielectric ceramics have been developed fast. The progresses and problems in microwave dielectric ceramics of high frequency, high dielectric constant or low-temperature sintering are reviewed. The structures and dielectric characteristics of various material systems are studied. The changing regularities of the dielectric characteristics and structures of microwave dielectric ceramics based on the ion substitutions are analyzed. The progress and production of microwave dielectric ceramic components for dielectric resonance, multilayer structure and functional module are described. Those materials and components related with low temperature co-fired technology are discussed emphatically. The relationship between microwave components structure and microwave characteristics is investigated. The future prospects of the material and its applications are provided.
