Description

Technical Field

[0001] This utility model relates to the field of Ka phased array satellite communication antenna technology, and in particular to a curved phased array antenna carrier. Background Technology

[0002] With the rapid development of communication technology, higher requirements are being placed on the stealth performance and communication capabilities of phased array antennas. To reduce the RCS characteristics of the antenna surface, certain measures must be taken to make the antenna surface conform to the aircraft skin, while simultaneously ensuring that the radio frequency signals of the phased array antenna are transmitted smoothly between the antenna surface and the TR components.

[0003] Currently, some low-RCS phased array antenna structures have emerged in China, such as coating the antenna surface with absorbing materials or using special-type radomes to reduce the antenna's RCS characteristics. However, these methods are not only limited in effectiveness but also have limitations due to their inability to meet stringent environmental requirements and finite envelope size. Compared to other phased array antenna types, there are currently no phased array satellite communication antennas with curved carrier plates in China. Utility Model Content

[0004] The purpose of this invention is to provide a curved phased array antenna carrier that can meet the requirements of cascading antenna surfaces and active components during antenna use, meet antenna feeding requirements, reduce antenna envelope size, achieve antenna lightweighting, and ensure low RCS characteristics of the antenna surface.

[0005] The technical solution to achieve the purpose of this utility model is: a curved phased array antenna carrier plate, including an upper cover plate, a button connector and a lower cover plate;

[0006] The upper surface of the carrier plate cover is curved, and a curved transceiver antenna surface is welded onto the upper surface. The antenna surface is shaped by the curved surface, and the curved surface maintains the same curvature as the mounting platform. The lower cover of the carrier plate is installed on the lower surface of the upper cover of the carrier plate, and an antenna TR assembly is installed below the lower cover of the carrier plate. Multiple button mounting holes are provided in the middle of the upper cover and lower cover of the carrier plate. Button connectors are installed through the button mounting holes between the upper cover and lower cover of the carrier plate to realize antenna cascading. Mounting flanges are provided around the upper cover of the carrier plate, and the upper cover of the carrier plate is installed on the carrier surface through the mounting flanges.

[0007] Furthermore, the flatness of the lower surface of the upper cover plate and the lower cover plate of the carrier plate is not less than 0.05 mm, so that the button connector can fully contact the pins on the surface of the antenna TR assembly.

[0008] Furthermore, the cover plate on the carrier plate is provided with upward-facing flanges around its perimeter to wrap the curved transceiver antenna surface; the flange has a dimensional tolerance of +0.05mm, and the flange, together with the pins, positions the curved transceiver antenna surface, ensuring a tight connection between the pins of the curved transceiver antenna surface and the button connectors in the button mounting holes, thus guaranteeing smooth communication.

[0009] Furthermore, the upper surface of the cover plate on the carrier plate is plated with gold for welding the cover plate on the carrier plate to the antenna surface, and the gold layer reduces the contact resistance.

[0010] Furthermore, the upper surface of the cover plate of the carrier plate is designed with vent holes, so that when the curved transceiver antenna surface is welded to the surface of the cover plate of the carrier plate, the gas on the welding surface can be discharged.

[0011] Furthermore, the cover plate on the carrier plate is locked to the curved transceiver antenna surface using a Phillips head M2 countersunk screw.

[0012] Furthermore, the cover plate on the carrier plate is machined from 6061 aluminum ingot and the surface is treated with natural conductive oxidation.

[0013] Furthermore, the inner cavity of the cover plate on the carrier plate and the mounting flange are provided with hollow weight-reduction grooves to reduce the weight of the cover plate on the carrier plate and achieve antenna lightweighting.

[0014] Furthermore, the bobby button connector consists of bobby buttons at both ends and a brass connector in the middle. Since the cover plate on the carrier plate adopts a curved surface design and the bobby button connector has limited elasticity, the length of each bobby button connector is different. By designing brass connectors of different lengths, the different installation positions and different length requirements of the bobby button connectors can be matched.

[0015] The button is woven from gold wire, with no wire joints or loose threads within 0.6mm at both ends. It is cylindrical in shape, with full ends and no voids. It has uniform density, a diameter of 0.38mm, a total length of 3mm, and a flat end face. Its compressibility is 15% of its length. By pressing the button tightly, a tight connection is achieved between the button connector and the curved transceiver antenna surface and the antenna TR assembly, ensuring uninterrupted radio frequency signal transmission.

[0016] Furthermore, the mounting position of the snap fastener inside the cover plate of the carrier plate is designed with a column to ensure the strength of the snap fastener, and to support and protect the snap fastener to prevent deformation or crushing.

[0017] Compared with the prior art, the significant advantages of this utility model are:

[0018] (1) The cascading of the Ka phased array satellite communication antenna surface and active components was realized, which met the power supply requirements of the Ka phased array satellite communication antenna;

[0019] (2) The main body of the carrier plate structure is made of 6061 aluminum alloy by integral milling to ensure the overall structural strength. The surface is treated with natural conductive oxidation to improve the corrosion resistance of the carrier plate.

[0020] (3) The upper surface of the carrier board is gold-plated, which improves the welding quality of the carrier board and the antenna surface during the welding process, reduces the problem of false soldering, and the gold layer effectively reduces the contact resistance and improves the electrical connection performance.

[0021] (4) The middle part of the carrier board is hollowed out to achieve antenna weight reduction;

[0022] (5) By adjusting the length of the button connector, the button connector can be adapted to different positions of the curved carrier plate;

[0023] (6) The design life of the button connector is ≥5000 times of repeated extension and retraction, which ensures the reliability of antenna installation, disassembly and maintenance.

[0024] (7) The working temperature of the button connector is -55~125°C, which can ensure the reliability of antenna cascading under various harsh environmental conditions, thus ensuring smooth communication;

[0025] (8) The carrier plate is designed with vent holes, which not only allows gas to be discharged in time during welding to prevent bulging, but also allows excess solder to flow into the side wall of the vent holes, increasing the welding area and improving the welding strength and reliability.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0033] like Figure 1 , Figure 2 , Figure 3 As shown, the present invention provides a curved phased array antenna carrier plate, including an upper cover plate 1, a button connector 2, and a lower cover plate 3.

[0034] The upper surface of the carrier plate cover 1 is curved, and a curved transceiver antenna surface is welded onto the upper surface. The antenna surface is shaped, and the curved surface maintains the same curvature as the mounting platform. The lower cover 3 of the carrier plate is installed on the lower surface of the upper cover 1 of the carrier plate, and an antenna TR assembly is installed below the lower cover 3 of the carrier plate. Multiple button mounting holes 4 are provided in the middle of the upper cover 1 and the lower cover 3 of the carrier plate. The button connector 2 is installed through the button mounting holes 4 between the upper cover 1 and the lower cover 3 of the carrier plate to realize antenna cascading. The upper cover 1 of the carrier plate is provided with mounting flanges 5 around its perimeter, and the upper cover 1 of the carrier plate is installed on the carrier surface through the mounting flanges 5.

[0035] As a specific example, the flatness of the lower surface of the upper cover plate 1 and the lower cover plate 3 of the carrier plate is not less than 0.05mm, ensuring that the button connector 2 is in full contact with the pins on the surface of the antenna TR assembly.

[0036] As a specific example, the cover plate 1 on the carrier plate is provided with upward-facing flanges around its perimeter to wrap the curved transceiver antenna surface; the flange has a dimensional tolerance of +0.05mm, and the flange, together with the pins, accurately positions the curved transceiver antenna surface, so that the pins of the curved transceiver antenna surface are tightly connected to the button connector 2 in the button mounting hole 4, ensuring smooth communication.

[0037] As a specific example, the upper surface of the cover plate 1 on the carrier plate is plated with gold to ensure the welding quality of the cover plate 1 on the carrier plate and the antenna surface during the welding process, reduce the problem of false soldering, and the gold layer effectively reduces the contact resistance and improves the electrical connection performance.

[0038] As a specific example, the upper surface of the cover plate 1 on the carrier plate is designed with vent holes 6. When the curved transceiver antenna surface is welded to the surface of the cover plate 1 on the carrier plate, the gas on the welding surface can be discharged to prevent voids and bubbles from forming.

[0039] As a specific example, the cover plate 1 on the carrier plate is locked to the curved transceiver antenna surface using a cross-slot M2 countersunk screw to prevent the antenna surface from detaching from the solder joint or warping.

[0040] As a specific example, the cover plate 1 on the carrier plate is machined from 6061 aluminum ingot and the surface is treated with natural conductive oxidation.

[0041] As a specific example, the inner cavity of the cover plate 1 on the carrier plate and the mounting flange 5 are provided with hollow weight-reduction grooves 7 to reduce the weight of the cover plate 1 on the carrier plate and achieve antenna lightweighting.

[0042] As a specific example, such as Figure 4 As shown, the bobby button connector 2 consists of bobby buttons 2-1 at both ends and a brass connector 2-2 in the middle. Since the cover plate 1 on the carrier plate adopts a curved surface design and the bobby button connector 2 has limited elasticity, the length of each bobby button connector 2 is different. By designing brass connectors 2-2 of different lengths, different installation positions and different length requirements of the bobby button connector 2 can be adapted.

[0043] like Figure 5 As shown, the button 2-1 is woven from gold wire, with no wire joints or loose threads within 0.6mm at both ends. It has a cylindrical shape with full ends and no holes. The overall density is uniform, with a diameter of 0.38mm and a total length of 3mm. The end face is flat, and the compressibility is 15% of the length direction. By pressing the button 2-1 tightly, the button connector 2 is tightly connected to the curved transceiver antenna surface and the antenna TR assembly, ensuring that the radio frequency signal is not interrupted.

[0044] As a specific example, such as Figure 6 As shown, the mounting position of the button connector 2 inside the cover plate 1 of the carrier plate is designed with a column 8 to ensure the strength of the button connector 2, and to support and protect the button connector 2 to prevent deformation and crushing.

[0045] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
