Abstract

The invention discloses a C-Ku dual-band integrated feed source. When transmitting signals, the C-band signal is radiated by the C-band feed port, propagates through the C / Ku coaxial waveguide, and radiates out through the horn of the C / Ku common radiation section. ;The Ku-band signal is radiated by the Ku-band feed section, propagates through the circular waveguide, and radiates out through the horn of the C / Ku common radiation section; when receiving the signal, the C-band signal is collected into the feed source through the C / Ku common radiation section horn, and C The band signal is transmitted to the C-band feed port through the C / Ku coaxial waveguide; the Ku-band signal is collected into the feed source through the C / Ku common radiation section horn, and the Ku-band signal is propagated to the Ku-band feed section through the circular waveguide. The present invention uses one multi-band feed source to replace two feed sources, which solves the trouble of installing the multi-band antenna on a communication vehicle and switching back and forth according to needs in the prior art, and solves the problems of weight and space.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a C-Ku dual-band integrated feed source. Background technique [0002] With the rapid development of aerospace and communication technology, satellite communication has been widely used in various industries. There are two types of satellite communication systems commonly used at present: C-band and Ku-band. The disadvantages of C-band are narrow communication frequency band, low anti-interference ability, and small antenna gain. The rain attenuation is relatively large. When it rains, the communication quality will decline or even be interrupted due to the rain attenuation. The current solution to this problem is that a communication vehicle is equipped with two antennas of Ku-band and C-band, which can be switched as needed. For a small communication vehicle, it is still more difficult to install two antennas, one is the weight is relatively heavy, and the ot...
