Description

Technical Field

[0001] This invention relates to the field of antenna technology, specifically to a lightweight, high-precision phased array antenna structure based on a large aspect ratio carbon nanotube. Background Technology

[0002] In recent years, there has been a clear trend towards miniaturization, mass production, and multifunctionality of satellites. Consequently, requirements have been put forward for a typical satellite payload—the phased array antenna—in terms of lightweight, low cost, high precision, high frequency band, and high gain.

[0003] As a typical and widely used on-board payload, phased array antennas follow the overall trend of satellites. The phased array antenna structure and assembly technology is key to the successful mass engineering application of antennas. Therefore, how to achieve low-cost, rapid, and high-precision phased array antenna assembly has become an urgent problem to be solved.

[0004] The current traditional formation mode is as follows: Figure 1 As shown, each column of antenna element modules requires a set of triangular mesh trusses between the outer frames of the two antennas. These mesh trusses are heavy, have complex molding processes, and are expensive. They are also prone to twisting after molding, resulting in low accuracy after arraying. Furthermore, the mesh trusses can only be located between each column of antenna element modules, leading to a large array spacing. These factors limit the ability to achieve sparse arraying of low-frequency, low-precision phased array antenna elements. Summary of the Invention

[0021] The phased array antenna unit is a complex deep-cavity thin-wall waveguide metal structural member, which is designed with a through hole, so that the middle layer longitudinal carbon tube, the lower layer transverse carbon tube and the middle layer transverse carbon tube can pass through the body. In addition, the back of the phased array antenna unit is designed with a mounting hole, which can be used to mount the warp and weft support. After the phased array antenna unit is arranged in a 16x8 manner to form a planar array, the warp and weft supports are uniformly distributed and mounted on the back of the planar array. At the same time, the warp and weft supports are also designed with through holes, and the upper layer transverse carbon tube and the upper layer longitudinal carbon tube can pass through the body.

[0024] The application has the following advantages:

[0025] (1) In the application, the large-aspect-ratio carbon tubes penetrate through the antenna unit and are fused together with the antenna unit, the compactness of the structure is improved, the antenna units can be arranged without gaps, compared with the traditional way of increasing triangular grid trusses for each column of antenna units, the arrangement density of the antenna units can be increased by 10% to 15%.

[0026] (2) In the application, the large-aspect-ratio carbon tubes replace the traditional triangular grid trusses. The grid trusses are heavy, the forming process is complex, the cost is high, the formed grid trusses are easy to twist, and the precision of the array is low. According to actual measurement, the flatness of the antenna array surface formed by the application is better than 0.2mm / 1m 2 ;

[0027] (3) In the application, the large-aspect-ratio carbon tubes can form discrete and spatial three-dimensional distribution, the traditional triangular grid trusses can only be limited to be concentrated, the discrete distribution has smaller structural stress and deformation gradient, so that the antenna unit can be made to be lighter and thinner, and the weight of the effective load of the array surface is reduced. The spatial three-dimensional distribution improves the structural mechanics connection efficiency, so that the weight of the support structure part of the array surface is lighter. Because of the two advantages, the antenna array surface of the application has excellent rigidity and strength, after the mechanical and thermal tests, the actual measurement shows that the structural precision does not change, and the structural stability is very high.

[0028] (4) Each antenna unit of the present invention is designed with mounting holes on the back and the array structure has excellent rigidity, which greatly increases the degree of freedom of arranging the electrical active units under the phased array antenna on the back of the antenna array, rather than the limited area of ​​the traditional antenna.
