Abstract

The invention discloses a feed source device capable of realizing antenna C / Ku band switching and a method thereof. A C-band feed source and a Ku-band feed source are respectively arranged on a reciprocating linear motion guide rail by two corresponding rotary assemblies at intervals; at the same time, reflecting focal points on an antenna surface are projected between the C-band feed source and the Ku-band feed source; the C-band feed source or the Ku-band feed source receives the reflecting focal points on the antenna surface by the linear motion of the linear motion guide rail; and the direction of polarization of the C-band feed source or the Ku-band feed source is adjusted by the rotation of the corresponding rotary assembly. The feed source device is simple and compact in structure and convenient to use; the automation control is adopted to receive the switching of C-band signals and Ku-band signals and adjust polarizing angles; and the feed source device is convenient and practical, and has strong practical applicability in a satellite communication system.

Description

technical field

[0001] The invention relates to an antenna feed source switching device and a method thereof, so that satellite signals of C band and Ku band can be exchanged and received on the same antenna. Background technique

[0002] At present, with the continuous development of satellite communication, it has become a consensus to apply satellite communication technology to the field of emergency communication. In the satellite communication systems of various industries, the satellite communication frequency bands used are different, among which the C-band and Ku-band are commonly used satellite communication frequency bands. In actual communication services, sometimes it is necessary to be able to receive not only the C-band signal of a certain satellite resource, but also the Ku-band signal of a certain satellite resource. At present, there are two ways to solve this problem: one way is to use two antennas, one antenna receives the C-band signal, and the other ant...
