Problems solved by technology

However, a single hollow interlayer structure can be used to prepare an integral rotator structure radome, but due to the high mold cost, low production efficiency, and large volume of the integral rotator structure radome (transportation costs are high and the radome is easily damaged by impact during transportation), etc., As a result, it is difficult to apply the radome with a hollow interlayer integral rotator structure in the field of civil communication with high cost requirements.

Embodiment 1

[0029] Such as Figure 4 The combined hollow sandwich structure radome shown in the figure has an appearance size of 0.8m in length x 0.8m in width x 1.5m in height. The cross section of the radome is a regular quadrilateral. , the second radome assembly, the third radome assembly and the fourth radome assembly; each radome assembly is composed of two parts: a wave-transmitting area and a connecting area, and the wave-transmitting area is a hollow sandwich structure consisting of a hollow interlayer fabric layer and a composite The reinforced fabric layer on the upper and lower surfaces of the hollow interlayer fabric layer is compounded. The thickness specification of the hollow interlayer structure is selected as 8mm. The merchant is Sinoma Science and Technology Co., Ltd. The resin system is an unsaturated resin system. The constant is 1.9, the loss tangent value is 0.006, the core layer of the hollow interlayer fabric layer is composed of fiber fabric units in the shape of...

Embodiment 2

[0035] It is basically the same as Embodiment 1, except that the section of the radome is a regular hexagonal column structure; six components with the same structure are connected end to end through special-shaped protrusions and special-shaped grooves to form a circumferentially closed structure; regular hexagonal The side length of the shape is 0.6m, the total height of the cover body is 2.5m; the wall thickness of the main body of the cover body is 5mm. Among them, the dielectric constant of the wave-transparent area 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-transmissive area and the connecting area. The wave-transmissive area adopts a hollow interlayer structure, which has the characteristics of good broadband wave transmittance, light weight, high strength, and anti-delamination, which fully meets the antenna-to-antenna requirements. The wave-transparent function of the cover; th...

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....
