[0026] Combine figure 1 , figure 2 and image 3 As shown, in one embodiment, a BUC connection structure is provided, including a flat-panel satellite antenna 100 and a BUC200. The flat-panel satellite antenna 100 is provided with a feed input terminal (not shown in the figure); the BUC200 is provided with a transmitter The waveguide end 211 is directly connected to the input end of the feed source.
[0027] In the above-mentioned BUC connection structure, the flat satellite antenna 100 and the BUC 200 are directly connected to the feed input terminal through the transmitting waveguide terminal 211 to realize signal transmission. The general flat satellite antenna 100 and the BUC 200 are connected through a waveguide with joints at both ends to realize signal transmission. Compared with the general flat satellite antenna 100 and the BUC connection structure, the waveguide and the joints provided at both ends of the still tube are omitted in this application, and the signal transmission path between the flat satellite antenna 100 and the BUC 200 is shortened. The signal transmission path between the two reduces the standing wave ratio of the transmission signal, thereby reducing the energy consumption requirements of the BUC200. At the same time, the structure in which the flat satellite antenna 100 and the BUC 200 are directly connected to the feed input terminal through the transmitting waveguide end 211 simplifies the connection structure of the BUC 200 and the flat satellite antenna 100 and saves costs.
[0028] In an embodiment, the BUC 200 includes a detachable BUC transmitting module 210 and a BUC functional module 220, the BUC transmitting module 210 and the BUC functional module 220 are signal-connected, and the BUC transmitting module 210 is provided with the transmitting waveguide end 211. When the BUC200 and the flat satellite antenna 100 are installed in the moving satellite system, since the BUC transmitting module 210 and the BUC function module 220 can be separated, the BUC transmitting module 210 and the BUC function module can be combined according to the spatial structure of the moving satellite system 220 is arranged separately, so that the structure of the satellite system in motion can be compact, and the overall structure size of the satellite system in motion can be reduced.
[0029] In an embodiment, the BUC connection structure further includes a signal transmission line 230. The two ends of the signal transmission line 230 are respectively connected to the BUC transmission module 210 and the BUC function module 220 to transmit between the BUC transmission module 210 and the BUC function module 220. signal of. The signal transmission line 230 has a simple structure for transmitting signals between the BUC transmitting module 210 and the BUC function module 220, and the signal transmission is stable and reliable.
[0030] In an embodiment, both ends of the signal transmission line 230 are respectively provided with a first plug connector 241 and a second plug connector 242. The first plug connector 241 is mated with the BUC transmitting module 210, and the second plug connector 242 is mated with the BUC function module 220. During installation, the first plug connector 241 and the second plug connector 242 are used to plug and connect the BUC transmitter module 210, the BUC function module 220, and the signal transmission line 230. The installation operation is simple.
[0031] In one embodiment, the signal transmission line 230 is a shielded cable, and the first plug connector 241 and the second plug connector 242 are both shielded connectors. When the signal transmission line 230 is a shielded cable, and the first plug connector 241 and the second plug connector 242 are both shielded connectors, both the shielded cable and the shielded connector can reduce the interference of signal transmission to the flat satellite antenna 100, thereby ensuring The flat satellite antenna 100 can work normally and stably.
[0032] In one embodiment, the flat satellite antenna 100 is provided with a mounting plate 120, and the BUC 200 is set on the mounting plate 120 and can move with the flat satellite antenna 100. The BUC200 is arranged on the mounting board 120, so that the BUC200 can move with the flat satellite antenna 100, which avoids the problem of loose connection between the BUC200 and the flat satellite antenna 100 due to relative movement, and thereby connects the transmitting waveguide end 211 to the feed input end Stable and reliable.
[0033] In an embodiment, the mounting plate 120 is a metal mounting plate 121, and the BUC 200 and the metal mounting plate 121 can be thermally conductively fitted. When the mounting board 120 is a metal mounting board 121, the metal mounting board 121 can increase the heat dissipation area, thereby reducing the operating temperature of the BUC200.
[0034] Specifically, in this embodiment, the mounting board 120 is located on the back of the flat satellite antenna 100. It should be explained that the flat satellite antenna 100 is provided with a transmitting surface 130 for transmitting and receiving signals, and the back refers to the side of the flat satellite antenna 100 facing away from the transmitting surface 130. This can prevent the BUC200 from affecting the signal transmission of the flat satellite antenna 100. In addition, in other embodiments, the aforementioned mounting plate 120 may also be located at other parts of the flat satellite antenna 100. For example, the mounting plate 120 is located between the back of the flat satellite antenna 100 and the transmitting surface 130.
[0035] In addition, it should be noted that the aforementioned mounting plate 120 may be a part of the flat-panel satellite antenna 100. Of course, the aforementioned mounting plate 120 may also be a plate or a plate frame mounted on the flat-panel satellite antenna 100.
