AI Technical Summary
Existing microwave dielectric ceramic materials have high dielectric loss in high-frequency communication, which makes it difficult to meet the requirements of modern communication technology for low-loss, high-Q materials, especially the technological upgrading needs in high-end application fields such as satellite communication, Beidou navigation and electronic countermeasures.
Using aluminate microwave dielectric material with the chemical formula YAZn3-xBxAlO7 (A=Sr, Ba, B=Co, Ni, 0≤x≤0.08), a single '114' configuration compound was prepared by ball milling and solid-state sintering. Combining the characteristics of low dielectric constant and ultra-low dielectric loss, the preparation process is simple and low-cost, making it suitable for large-scale production.
It significantly reduces dielectric loss and improves the stability of microwave signal transmission. It is suitable for systems such as microwave substrates and dielectric antennas, meeting the low cost and high reliability requirements of high-frequency communication. It is applicable to fields such as satellite communication, Beidou navigation, electronic warfare, 5G and the Internet of Things.
