The pitch supporter 303 is at an angle to the horizontal rotary bracket 302 for better support to the antenna communication module.

(28) The horizontal rotary bracket 302 is shaped as polygon and is shown as a triangle in the figures, providing stability, the driving modules are connected in the polygon at each corner. The horizontal rotary brackets 302 is not limited to triangle as shown in the figures, it can be adjusted according to actual requirement. A first limit wheel 305 clamping at the rail base 301 is provided at each connection point of the horizontal rotary brackets 302.

It is possible to arrange the equipment box 313 at any suitable positions that does not affect the normal operation of the entire device, and such suitable positions also fall within the scope of protection of the present disclosure.

(32) As shown in FIG. 8, the equipment box 313 is located on the horizontal rotary bracket 302. This arrangement makes the entire antenna more steady than the Embodiment 1, 2, or 3 due to its center of gravity going down. Moreover, the equipment box 313 can cover the entire horizontal rotary bracket 302 and function as the horizontal rotary bracket 302, this manner also falls within the scope of protection of the present disclosure.

Embodiment 2

(33) Referring to FIG. 9, the Embodiment 2 employs manual regulating mode, i.e. having the driving module being modified and human machine interaction interface, which differs from the Embodiment 1. The driving module comprises a bearing wheel 308, a second limit wheel 310, a locking element 316 and human machine interaction interface. The bearing wheel 308 is configured on the top of the rail base 301 to bear the weight of the communication module; the second limit wheel 310 is arranged on one side of the rail base 301 and the first limit wheel 305 is located on the other side of the rail base 30, to limit the movement of the driving module along the rail base 301; the locking element 316 is located at the same side with the second limit wheel 310 for locking the second limit wheel 310 after the antenna is aligned to the target satellite, thereby the second limit wheel 310 will not move under external forces and the accuracy of signal received is ensure. The human machine interaction interface is located at the same side with the antenna communication module or the supporting module, and the users can observe thereon whether the antenna is aligned to the target satellite to anticipate the timing to lock the horizontal structure.

(34) It should be noted that, the second limit wheel 310 is shown in the form of gear, as shown in FIG. 10, but the second limit wheel 310 is not limited to a gear, any suitable shape element having same function, such as wheel structures with a thread or a certain coefficient of friction on its outer wall, is possible.

(35) The entire weight in this embodiment is further reduced for omitting the driving motor, and the portability is enhanced.

Embodiment 3

(36) Referring to FIG. 12, this embodiment employs the antenna reflector 312 which was installed in forward direction, which differs from the Embodiment 1 & 2 where the antenna reflector 312 was installed in backward direction. The difference therebetween can be observed in FIGS. 3-4 of the embodiment 1, and FIG. 12 of this embodiment.

(37) It is two different ways to utilize the antenna for the antenna reflector 312 being installed in forward direction or backward direction. Both ways have the same antenna gain and capacity to receive signals, but have differences that, antenna reflector 312 being installed in forward direction is used in an environment with a broad view ahead, while antenna reflector 312 being installed in backward direction is used in an environment with a broad view above, preventing from gathering dust or snow thereon, and has better wind-resistant and saves space.

Embodiment 4

(38) This embodiment is different from the embodiment 1-3, in that planar waveguide horn array antenna is used in the antenna communication module, which is specifically shown in FIG. 13.

(39) Therefore, the installing direction can vary according requirement in actual application, which broaden the usable range.

(40) Although the present invention has been disclosed in the form of preferred embodiments and variations thereon, it will be understood that numerous additional modifications and variations could be made thereto without departing from the scope of the invention.

(41) For the sake of clarity, it is to be understood that the use of a or an throughout this application does not exclude a plurality, and comprising does not exclude other steps or elements.
