Fig. 1 is a schematic diagram of the overall structure of the portable satellite antenna of this embodiment.

Referring to FIG. 1 , the portable satellite antenna of this embodiment includes a base 100 , a reflector 200 and a feed device 300 . Wherein, the base 100 is the supporting structure of the entire portable satellite antenna, supporting the reflector 200 and the feed device 300 . Both the reflecting plate 200 and the feed source device 300 are detachably connected to the supporting base 100 . Therefore, the user can disassemble the reflector 200 and the feed source device 300 from the base 100 when carrying them, and package and carry them separately, which greatly increases the portability of the satellite antenna.

Referring to Fig. 1, in this embodiment, the reflector 200 is connected with the feed device 300, and its whole can be separated from the base 100. When carrying it, the user can split the satellite antenna into two parts and carry it separately, or disassemble it. After finishing together, pack and carry.

In other embodiments, the reflection plate 200 and the feed device 300 can also be separated and installed on the base 100 respectively. When carrying, the reflecting plate 200 and the feed source device 300 can be disassembled and packaged for carrying.

Furthermore, in this embodiment, the reflection plate 200 is made of carbon fiber material, and the angle between the reflection plate 200 and the base 100 can be adjusted, and the angle between the feed device 300 and the base 100 can also be adjusted. As shown in FIG. 1 , when the angle between the reflector 200 and the base 100 is adjusted, or the angle between the feed device 300 and the base 100 is adjusted, the relative position between the reflector 200 and the feed device 300 will change. change. Especially when the reflector 200 and the feed device 300 are detached from the base 100, the included angle between the reflector 200 and the feed device 300 can be adjusted to minimize the angle between them, thereby facilitating carried by the user.

As can be seen from the above description, the portable satellite antenna base 100 of this embodiment is detachably connected to the reflector 200 and the feed source device 300, so that the reflector 200 and the feed source device 300 are connected to the base 100 when in use, and when carried The reflecting plate 200 and the feed source device 300 are detached from the base 100, so as to be convenient to carry. When carrying, the included angle between the feed source device 300 and the reflecting plate 200 can be adjusted to the minimum. When in use, the included angle between the reflector 200 and the base 100 can be adjusted to optimize the signal reception effect of the satellite.
