CROSS-REFERENCE TO RELATED APPLICATION

BACKGROUND OF THE INVENTION
[0003] In the current application, an offset feed satellite antenna generally employs a box structure. As shown in Fig.1, the whole antenna is generally formed by an antenna face 1-1, a feed source support 1-2, a feed source system, an azimuth pitching drive component 1-4, an electrical box 1-3, a windproof support 1-6 and a carrying handle 1-5, etc. An electrical box body and the azimuth pitching drive component are mounted on a bottom plate of the antenna structure, and an antenna feed system is mounted on the azimuth pitching drive component of the antenna. Such an antenna structure can meet the requirements of ordinary communication and has the advantages of compact volume after being folded and large electrical box volume for accommodating multiple communication machines. However, it also has the following disadvantages: [0004] The electrical box is located on the bottom of the antenna, thus it has no wading ability; [0005] The feed source support part has devices such as a power amplifier and a RF, etc., and the weight is large, while no corresponding counterweight is provided on the back of the antenna face, thus the gravity center of the pitching rotating part is located at the front end, and a larger retarder and a larger motor are required during pitching rotation; [0006] The antenna electrical box is located at the front end of the antenna, it may be directed exposed to the sunlight at a high temperature in summer, which may result in the failure of communication devices due to the abnormal rise of temperature in the box; [0007] The antenna face employs a multi-petal assembling mode, and a certain assembling time is needed for antenna construction; [0008] The weight is large, which cannot meet the increasingly miniaturization requirement on the antenna.
[0009] In conclusion, such an antenna structure is generally applied to a situation of high-capacity broadband communication.
[0010] China Patent Publication No. CN104518271A discloses "A Portable Automatic Satellite-Searching System", which employs a prime focus antenna structure. As shown in Fig.2, in this solution, a quadripod is employed as the support structure, an azimuth pitching drive structure is placed on the quadripod 2-1, an antenna face 2-2 employs a multi-petal assembling solution, and a power amplifier RF system 2-3 is placed on the back of the antenna face. Such a solution has the following advantages: the wading ability of the antenna may be improved; the electrical box may be prevented from being exposed to direct sunlight; and the pitching center is near to the rotational axis, etc. However, it also has certain disadvantages as follows.
[0011] 1. The antenna face generally employs eight-petal assembling, and the assembling and construction time for the antenna face is long.
[0012] 2. The feed source rod of the antenna face needs to be disassembled during folding, and it needs to be connected onto the central disc of the antenna face via screw thread in use.
[0013] 3. The overall structure of the antenna is heavy, thus it can only be carried in a box, rather than being carried on the back, which is inconvenient in a complex terrain such as a mountainous area.
[0014] 4. The speed of the manual azimuth and pitching adjustment structure is low, and there exists no fast angle adjustment and angle fine adjustment structure.
[0015] The volume of the control box is small, and it can only accommodate the control part and the drive part of the antenna itself, with no space for a built-in modem and other business devices.
