It also relates to a technical solution and a use method of the small antenna. Background Art

[0002] This type of antenna provides accurate guidance information such as landing direction, course and distance to the aircraft. Based on this information, the aircraft aligns with the runway and approaches and lands at a given direction, altitude and glide angle to ensure that the deviation of the landing point is within the specified range.

[0052] The upper antenna and the lower antenna are provided with a precision hinge 31 and a locking buckle 32 , and the upper antenna and the lower antenna are connected together through the precision hinge 31 and the locking buckle 32 .

[0053] The retractable and foldable tripod comprises an upper antenna connector 33, a lower antenna connector 34, an antenna connecting rod 35, a connecting rod rotating shaft 36, a carbon fiber support rod 37, a stable foot 38, a bubble level 39 and a tripod connecting buckle 40;

[0054] The upper antenna connector 33 is connected to the carbon fiber support rod 37;

[0058] The tripod connection buckle 40 is installed on the upper antenna connection piece 33 and the lower antenna connection piece 34 .

[0059] Furthermore, when the device is used, the antenna T component 1 is connected into a load-bearing body through the front load-bearing beam 4, the rear load-bearing beam 5, and the front and rear beam connecting parts 6, which plays a load-bearing role and will not damage the antenna T component 1 while bearing the weight; the upper antenna shell 9, the digital board maintenance cover 15, the upper cover 12, the lower cover 13, and the antenna cover 14 are installed on the load-bearing body to seal the internal antenna and can adapt to various severe weather environments; the antenna R component 2, the antenna digital board 3, the divider 25 and other units are installed on the load-bearing body inside the antenna, and can be disassembled and maintained through the maintenance cover on the antenna shell.

[0060] The antenna reflectors 10 on both sides of the antenna are placed outside the antenna and connected to the upper antenna housing 9 through spring hinges 11. When the antenna is in storage, the antenna reflectors 10 are pressed against both sides of the antenna housing through the reflector locking latches 18, thereby reducing the storage volume of the antenna. When the antenna is in working state, the antenna reflectors 10 on both sides can be automatically unfolded by loosening the reflector locking latches 18; the antenna is divided into upper and lower parts, which are connected and locked by precision hinges 31 and locking buckles 32.

The upper and lower antenna parts can be folded, and after folding, the two antenna parts are locked in position by the upper and lower antenna locking devices 24, thereby protecting the antenna and the precision hinges 31 from damage during transportation and storage.

[0061] The antenna tripod uses a carbon fiber support rod 37, which greatly reduces the weight while ensuring the strength of use. The connection between the antenna tripod and the upper and lower antennas adopts a U-shaped connection structure. The antenna tripod and the upper and lower antennas can be quickly connected by plugging the antenna tripod and the upper and lower antennas. The antenna tripod and the upper and lower antennas are quickly locked by connecting buckles. There are two U-shaped antenna connectors on the antenna tripod, one at the bottom of the lower antenna and the other at the lower middle part of the upper antenna, which ensures that the center of gravity of the antenna tripod is in the best position after the connection with the upper and lower antennas. The antenna tripod is directly connected to the upper antenna connector 33, and the antenna tripod is connected to the lower antenna connector 34 through the antenna connecting rod 35, which can ensure the stability of the antenna. The antenna tripod can be quickly retracted by adjusting the lower antenna connector 34 and the carbon fiber support rod 37. The carbon fiber support rod 37 adopts a multi-section structure, which can ensure the height of the antenna tripod after unfolding and reduce the volume of the antenna tripod after retracting.

[0062] There are two antenna suspension parts 23 at the rear of the upper antenna, which can realize the expansion of the antenna and can hang various auxiliary equipment; when the antenna enters the working state, first unfold the tripod, observe the bubble level 39 to adjust the tripod to a horizontal state, then unfold the antenna and lock the connection buckles of the upper and lower antennas, and finally place the antenna on the two U-shaped antenna connectors of the tripod and lock the connection buckles. When the antenna enters the transportation and storage state, the reverse operation can be performed.

[0063] Through the cooperation of precision hinges 31, locking buckles 32, carbon fiber support rods 37, front load-bearing beams 4, rear load-bearing beams 5 and front and rear beam connectors 6, the antenna is designed to be miniaturized and segmented. Each segment of the antenna is an integral unit, which is connected into one by various high-precision structures. When unfolded, it is an antenna in a working state, and when folded and stowed, it is an antenna in a transport and storage state. The antenna can be miniaturized and easy to carry and transport, so it is suitable for harsh outdoor environments and is easy and simple to maintain.

[0064] Through the cooperation of the tripod connector 19, the antenna connecting rod 35 and the carbon fiber support rod 37, the antenna can be set up through the tripod. The tripod can be retracted and folded. When extended, it is in the working state, and when retracted and folded, it is in the transportation and storage state. Therefore, it can be quickly set up without the aid of tools, which greatly expands the use scenarios of the antenna.

[0065] Working principle: The antenna T component 1 is connected into a load-bearing body through the front load-bearing beam 4, the rear load-bearing beam 5, and the front and rear beam connecting parts 6, which plays a load-bearing role and will not damage the antenna T component 1 while bearing the weight; the upper antenna shell 9, the digital board maintenance cover 15, the upper cover 12, the lower cover 13, and the antenna cover 14 are installed on the load-bearing body to seal the internal antenna and can adapt to various severe weather environments; the antenna R component 2, the antenna digital board 3, the splitter 25 and other units are installed on the load-bearing body inside the antenna, and can be disassembled and maintained through the maintenance cover on the antenna shell.
