Aluminum nitride ceramics also play an important role in the field of microwave communication:

High frequency electronic devices: Aluminum nitride ceramics have excellent microwave transmission performance and dielectric properties, and are often used as substrate materials for microwave devices, such as microwave antennas, filters, couplers, etc. Its stable dielectric properties and high-frequency transmission performance make it widely used in microwave communication systems

Microwave packaging material: The high-temperature stability and good mechanical properties of aluminum nitride ceramics make it an ideal choice for packaging materials of microwave devices. In microwave communication systems, packaging materials need to have good high temperature resistance and corrosion resistance to ensure the stability and reliability of devices

Microwave window material: In microwave communication systems, microwave windows are used for transmitting microwave signals, and aluminum nitride ceramics are often used as microwave window materials due to their good transmission performance and high temperature resistance, to protect the microwave signal transmission path and improve the performance of communication systems

Antenna support material: The high strength and corrosion resistance of aluminum nitride ceramics make it an ideal material for antenna support structures in antenna systems. In microwave communication systems, antenna support structures need to be able to withstand harsh environments such as wind and rain, and maintain stable performance
