[0009] In some embodiments, three evenly spaced mounting holes are provided on the mounting sleeve.

[0010] In some embodiments, the mounting plate is provided with a plurality of equally spaced No. 2 mounting holes.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Example 1: Please refer to Figures 1 to 9The utility model provides a technical solution: a high-stability and high-transmittance prepreg antenna system protection device, including a protection mechanism 1, the protection mechanism 1 includes a protective side plate 2, a raised plate 3 and a mounting plate 4 connected to form an integral body; the protective side plate 2 and the mounting plate 4 surround the peripheral part of the raised plate 3; on the inner wall surface of the mounting plate 4, a mounting sleeve plate 7 is symmetrically arranged; the edges of the protective side plate 2 and the mounting plate 4 are respectively provided with a second sleeve edge 9 and a first sleeve edge 5; the protective side plate 2, the raised plate 3, the mounting plate 4 and the mounting sleeve plate 7 are all an integrated structure composed of an upper skin layer 15, a lower skin layer 16 and a honeycomb core layer 17 sandwiched therebetween, the antenna is placed in the inner cavity of the protection mechanism 1, the second sleeve edge 9, the first sleeve edge 5 and the mounting sleeve plate 7 ensure the antenna position to determine the angle between the electromagnetic wave and the protective cover.

[0032] By providing an integrated structure consisting of an upper skin layer 15, a lower skin layer 16 and a honeycomb core layer 17 sandwiched therebetween, as well as a plurality of socket recesses and socket edges that cooperate with the antenna system, multi-directional three-dimensional positioning and fitting installation are achieved. In combination with a plurality of mounting holes provided on the edge of the device, the protective device can provide stable and effective protection for the antenna system.

[0033] In this embodiment, if Figure 1 and Figure 2 As shown, the protective side plate 2 and the mounting plate 4 are provided with a plurality of evenly distributed mounting holes 6, the mounting sleeve plate 7 is provided with evenly distributed No. 3 mounting holes 10, and the mounting plate 4 is provided with a plurality of evenly distributed No. 2 mounting holes 8, so that the protective side plate 2, the mounting plate 4 and the mounting sleeve plate 7 can be physically connected to the antenna system by positioning the plurality of holes around the ring, thereby increasing stability and practicality.

[0034] In this embodiment, if Figure 2 and Figure 3 As shown, the connection between the No. 2 sleeve edge 9 and the protective side plate 2 and the connection between the No. 1 sleeve edge 5 and the mounting plate 4 are both provided with a No. 1 sleeve recess 11, the raised plate 3 is connected to the mounting sleeve plate 7, the connection between the raised plate 3 and the protective side plate 2 and the connection between the raised plate 3 and the mounting sleeve plate 7 are both provided with a No. 2 sleeve recess 12, and the connection between the protective side plate 2 and the mounting plate 4 is provided with a No. 3 sleeve recess 13. The design of the No. 1 sleeve recess 11, the No. 2 sleeve recess 12 and the No. 3 sleeve recess 13 enables the device to fit tightly with the external shell of the antenna, improves the connection adaptation rate, and thereby reduces the gap to avoid the influence caused by the invasion of dust and impurities.

[0035] In this embodiment, if Figure 2 and Figure 3As shown, the opposite surfaces of the two mounting plates 7 are provided with symmetrically distributed anti-obstruction grooves 14, which are matched with the protrusions on the antenna system housing. This arrangement not only improves the adaptability of the protective device, making it widely applicable to antenna systems of different models, but also significantly enhances the stability and reliability during the installation process.

[0036] In this embodiment, if Figures 5 to 8 As shown, the honeycomb core layer 17 is a highly wave-transmitting NOMEX aramid material with a thickness of 3.5mm-10mm, which is designed to take into account the mechanical properties of the material and the wave-transmitting requirements, ensuring that it can show good wave-transmitting effects in different application scenarios. The loss tangent value is 0.0025-0.006. This value range ensures the low-loss characteristics of the material during electromagnetic wave transmission, effectively reduces signal attenuation, and improves transmission efficiency. The dielectric constant is 1.06-1.67. This dielectric constant range is not only conducive to the penetration of electromagnetic waves, but also can adjust the electromagnetic compatibility of the material to a certain extent, further enhancing its applicability in complex electromagnetic environments.

[0037] In this embodiment, if Figures 5 to 8 As shown, the upper skin layer 15 and the lower skin layer 16 are composed of fiber-reinforced material and resin prepreg material with a thickness of 1.5mm-6mm. The fiber-reinforced material is quartz fiber, and the resin matrix is ​​highly transparent bisphenol A cyanate resin with a loss tangent value of 0.004-0.006 and a dielectric constant of 3.3-3.5, which can reduce the loss of the antenna in the electromagnetic wave transmission process. Specifically, the selected quartz fiber, with its superior mechanical properties and environmental resistance, can provide solid support and protection for the overall structure. Bisphenol A cyanate resin not only has excellent physical and mechanical properties, but also has unique wave transmission performance, which greatly reduces the energy loss of the antenna in the electromagnetic wave transmission process, thereby improving the stability and reliability of the protection device.

[0038] Example 2: Please refer to Figures 1 to 5 , the technical solution provided by the utility model:

[0039] Different from Example 1, the upper skin layer 15 and the lower skin layer 16 are composed of fiber-reinforced material and resin prepreg material, and the resin matrix is ​​a highly wave-transmitting dicyclopentadiene cyanate resin. The unique molecular structure of the dicyclopentadiene cyanate resin gives it more excellent dielectric properties. Products made of dicyclopentadiene cyanate resin can better resist moisture erosion, maintain stable performance, and reduce performance degradation, short circuit and other problems caused by moisture, thereby improving the stability and reliability of the protection device.

[0040] Example 3: Please refer to Figures 1 to 5 , the technical solution provided by the utility model:

[0041] Different from Example 1, the upper skin layer 15 and the lower skin layer 16 are composed of fiber-reinforced material and resin prepreg material, and the resin matrix is ​​a highly wave-transmitting phenolic cyanate resin. The phenolic cyanate resin has more excellent mechanical strength, can better withstand external impact and resist deformation, has excellent flame retardancy, and has the flammability advantages of high molecular flame-retardant polyvinyl chloride and composite polyvinyl chloride. Compared with bisphenol A cyanate resin, it can more effectively prevent the spread of fire and reduce the risk of fire. The chemical stability of phenolic cyanate resin is very high, and chemically active substances are not easy to corrode it, thereby improving the stability and reliability of the protective device.
