Example Embodiment

[0028] Example 1

[0029] Such as Figure 4 The combined hollow sandwich structure radome shown has an appearance size of 0.8m long×0.8m wide×1.5m high. The cross-section of the radome is a regular quadrilateral, which is composed of 4 components with the same structure, followed by the first radome component , The second radome assembly, the third radome assembly and the fourth radome assembly; each radome assembly is composed of two parts: the wave transmission area and the connection area. The wave transmission area is a hollow sandwich structure, which is composed of a hollow sandwich fabric layer and a composite The reinforced fabric layer on the upper and lower surfaces of the hollow interlayer fabric layer is composited. The thickness specification of the hollow interlayer structure is 8mm. The merchant is Sinoma Technology Co., Ltd., the resin system is unsaturated resin system, and the merchant is DSM. The constant is 1.9 and the loss tangent value is 0.006. The core la...

Example Embodiment

[0034] Example 2

[0035] It is basically the same as Embodiment 1, except that: the cross-section of the radome is a regular hexagonal cylindrical structure; 6 components with the same structure are connected end to end through special-shaped protrusions and special-shaped grooves to form a circumferentially closed structure; The side length is 0.6m, the total height of the cover is 2.5m; the main wall thickness of the cover is 5mm. The dielectric constant of the wave-transmitting region is 1.85, and the loss tangent value is 0.006.

[0036] The radome components of the above examples are composed of two parts: the wave-transmitting area and the connecting area. The wave-transmitting area adopts a hollow sandwich structure, which has the characteristics of good broadband transmission rate, light weight, high strength and anti-layering, which fully meets the requirements of antenna to antenna The wave-transmitting functionality of the cover; the connection area is a solid glass fi...

Abstract

The invention discloses a combined type antenna beautifying cover with a hollow sandwiched structure. The combined type antenna beautifying cover comprises more than two antenna cover assemblies, wherein each antenna cover assembly comprises a hollow sandwiched wave-transmission region and solid glass steel connecting regions arranged at the two ends of the hollow sandwiched wave-transmission region; special-shaped inserting slot connecting pieces are arranged on the solid glass steel connecting regions; all antenna cover assemblies are connected in sequence through the special-shaped inserting slot connecting pieces to form a closed structure; and the hollow sandwiched wave-transmission region consists of a hollow sandwiched fabric layer and reinforced fabric layers which are compounded on the upper and lower surfaces of the hollow sandwiched fabric layer. The antenna beautifying cover provided by the invention has excellent broadband wave-transmission property and rapid combination function; delamination resistance and other mechanical properties of the antenna cover are ensured; a phenomenon of damage of the antenna cover caused by wind load in the use process can be avoided; the antenna beautifying cover has excellent characteristics of low loss, high wave transmissivity and other electrical properties, and light weight and high strength; and meanwhile, the problem that rapid connection of the existing antenna cover with a hollow sandwiched structure cannot be realized in the prior art is solved.

Description

technical field [0001] The invention belongs to the field of communication, and in particular relates to a combined antenna beautification cover with a hollow interlayer structure with high wave permeability. Background technique [0002] Antenna beautification cover (referred to as radome) is one of the main components used to protect the antenna in the cover to work normally under various harsh environmental conditions. It is a dielectric shell used to protect the antenna and transmit electromagnetic signals, so the radome is required The material has excellent strength, rigidity, waterproof sealing and broadband wave transmission performance. [0003] At present, the materials used in radome are mainly single-layer thin-walled solid structure, foam / honeycomb sandwich structure and hollow sandwich structure. Due to its simple processing technology and high strength, the single-layer thin-walled solid structure is currently widely used in the field of civil communications....
