Problems solved by technology
[0005] However, the structure of OMJ in this document (see the above paper for the meaning of OMJ) is more complicated to process, and the polarization output forms of C-band and Ku-band are relatively simple, and there is still room for improvement
[0006] Yuan Long of Chengdu Jinjiang Electronic System Engineering Co., Ltd. applied for a patent "A Receiving System for a Tri-Band Feed Network" in 2016, which disclosed the principle of a C / X / Ku tri-band multiplexing feed network Block diagram, but does not give the design method and structural form of the core components
In addition, although the network has achieved triple-band sharing, there is still room for improvement in performance

The invention discloses a C / X / Ku broadband three-frequency shared feed source network, belonging to the technical field of feed source networks. The C / X / Ku broadband three-frequency shared feed sourcenetwork includes two parts including a feed resource horn and a microwave network, and 2 ports of a C band, 2 ports of an X band and 2 ports of a Ku band are simultaneously outputted. The horizontally polarized and vertically polarized simultaneous output or the left-handed circularly polarized and right-handed circularly polarized simultaneous output of the C band can be achieved, and the Ku-band line polarization fine adjustment is realized by rotating a 180-degree phase shifter. According to the system, an antenna can efficiently receive satellite signals of three frequency bands C, X andKu at the same time, the utilization efficiency of the antenna is greatly improved, the installation and use are convenient, and the C / X / Ku broadband three-frequency shared feed source network is an important improvement to the prior art.
Description
Technical field [0001] The invention relates to the technical field of feeder networks, in particular to a C / X / Ku broadband three-frequency shared feeder network. Background technique [0002] With the rapid growth of the society’s demand for satellite communications and the rapid development of navigation measurement and control technology, in order to make full use of satellite resources, more and more satellites work in dual-frequency or more frequency bands, which can expand the communication capacity and greatly Improve antenna utilization. Currently, there are more dual-band satellites such as C / Ku, X / Ka, and S / X and three-band satellites such as C / X / Ku and S / X / Ka. The development of integrated multi-band satellites is the future trend. At the same time, the satellite ground station antenna system must keep up with the development needs of the times, increase the communication capacity of the satellite ground station antenna, and improve the utilization rate of the satell...
