Research on Key Technologies of C/Ku Dual-Band Satellite Communication

The demand for widening the C-band of the satellite frequency band in the communication field has increased, with the abundance of satellite resources and the increasing demand for satellite communication, and the use of the Ku-band has become more frequent. Some satellites can use the C-band and Ku-band simultaneously. This paper analyzes the key technologies of C/Ku band antenna, discusses the feasibility of dual band simultaneous working, and analyzes characteristic of rain attenuation and compensation method of Ku-band at last.
