The general flat satellite antenna 100 and the BUC200 are connected by a waveguide having connectors at both ends thereof to realize signal transmission. Compared with the general flat satellite antenna 100 and BUC connection structure, the flat satellite antenna 100 and the BUC connection structure have the advantages that the waveguide tube and the joints arranged at the two ends of the waveguide tube are omitted, the path for transmitting signals between the flat satellite antenna 100 and the BUC200 is shortened, the standing-wave ratio of the transmitted signals is reduced by shortening the path for transmitting signals between the flat satellite antenna 100 and the BUC200, and therefore the energy consumption requirement of the BUC200 is reduced. Meanwhile, the connection structure of the BUC200 and the flat satellite antenna 100 is simplified through the structure that the transmitting waveguide end 211 and the feed source input end are directly connected, and the cost is saved.
In an embodiment, the BUC200 includes a BUC transmitting module 210 and a BUC function module 220, which are separable, the BUC transmitting module 210 and the BUC function module 220 are in signal connection, and the BUC transmitting module 210 is provided with the transmitting waveguide end 211. When the BUC200 and the flat-panel satellite antenna 100 are installed in a satellite system in motion, the BUC transmitting module 210 and the BUC functional module 220 can be separated, and the BUC transmitting module 210 and the BUC functional module 220 can be separately arranged according to the space structure of the satellite system in motion, so that the structure of the satellite system in motion is compact, and the overall structure size of the satellite system in motion is further reduced.
In an embodiment, the BUC connection structure further includes a signal transmission line 230, and two ends of the signal transmission line 230 are respectively connected with the BUC transmitting module 210 and the BUC function module 220 to transmit a signal between the BUC transmitting module 210 and the BUC function module 220. The structure for transmitting the signal between the BUC transmitting module 210 and the BUC functional module 220 by the signal transmission line 230 is simple, and the signal transmission is stable and reliable.

When the BUC connection structure is used in the satellite system for satellite communication in motion, the base 410 can bear and mount the BUC connection structure; meanwhile, the alignment angle between the flat satellite antenna 100 and the satellite can be changed by rotating the BUC connecting structure, and the purpose that the flat satellite antenna 100 tracks the satellite is further achieved.
It should be noted that a rotating bracket 420 is disposed between the base 410 and the BUC connection structure, and the rotating bracket 420 can drive the BUC connection structure to rotate so that the flat-panel satellite antenna 100 can track a satellite. The rotating bracket 420 is typically a two-axis rotating bracket that allows the BUC connection to move in an arcuate curve.
Specifically, the structure of the universal joint can be used for reference by the two-axis rotating support. Of course, in order to adjust the position of the BUC connecting structure conveniently, the two-axis rotating bracket is provided with two motors, and the two-axis rotating bracket can be controlled to rotate in two directions through the motors.
