Description

Technical Field

[0001] This application relates to the field of communications, and more particularly, to an antenna and a network device. Background Art

[0002] Since China entered the 5G mobile communication era, in-depth signal coverage both indoors and outdoors has been facing various challenges. For example, as the operating frequency band increases, more losses occur when electromagnetic waves propagate in space. This requires blind spot coverage in various outdoor scenarios, that is, on the basis of existing network coverage, through additional facilities or technical means, to make up for or improve the insufficient coverage of network signals in certain areas. For outdoor antennas, due to the deep misunderstanding and resistance of residents to electromagnetic radiation, and the strict restrictions on the installation of rooftop equipment in newly built communities, traditional antennas, because of their large weight, large volume, and obvious visual effects, face problems such as difficult site selection, difficult access, and easy damage. Summary of the Utility Model

[0003] This application provides an antenna and a network device. The antenna can ensure a light structure while meeting the reliability requirements for outdoor use.

[0004] In a first aspect, an antenna is provided. The antenna includes: a radiation module, an antenna cover, and an antenna bottom cover.

The radiation module is configured to allow at least part of the incident light to pass through the transparent area. The transparent area includes: at least one antenna element.

[0006] In combination with the first aspect, in some implementations of the first aspect, the radome includes a first surrounding frame, which is disposed inside the radome, and a closed groove is formed between the first surrounding frame and the edge of the radome. The height of the first surrounding frame is lower than the height of the edge of the radome; the antenna bottom cover includes a second surrounding frame, which is disposed inside the antenna bottom cover, and the height of the second surrounding frame is higher than the height of the edge of the antenna bottom cover. The first surrounding frame and the second surrounding frame are used to fix the transparent area.

Since the first surrounding frame and the second surrounding frame form a stable structure, it helps to closely combine the radome and the antenna bottom cover, ensuring the mechanical strength and stability of the overall antenna.

This requires blind - spot coverage in various outdoor scenarios, that is, on the basis of the existing network coverage, through additional facilities or technical means, to make up for or improve the insufficient coverage of network signals in certain areas. For outdoor antennas, due to the deep misunderstanding and resistance of residents to electromagnetic radiation, and the strict restrictions on the installation of rooftop equipment in newly built communities, traditional antennas, because of their large weight, large volume, and obvious visual effects, face problems such as difficult site selection, difficult access, and easy damage.

[0039] The present application provides an antenna and a network device. The antenna can ensure portability of the structure while meeting the reliability requirements for outdoor use.

[0040] In one embodiment, the antenna includes a radiation module, an antenna cover, and an antenna bottom cover.

[0063] Next, taking Figures 1 to 8 as an example, the structure of the above antenna will be introduced in detail.

[0064] Figure 1 are the front view and the axial view of an antenna provided by an embodiment of the present application, where Figure 1 in (a) is the front view of the antenna, Figure 1 in (b) is the axial view of the antenna.

[0065] As shown in Figure 1 in (a), the area within the red dashed box is the transparent area, which can be made of polycarbonate material or polymethyl methacrylate material. Incident light can pass through this transparent area, and the periphery of this transparent area is the outer shell of the radome, which can also be called the shielding area.

[0066] Figure 2It is an exploded view of an antenna provided by an embodiment of the present application.

[0067] As Figure 2 shown, the antenna may include: an antenna bottom cover, a transparent radiation module, an antenna cover, a circuit component, a side mounting bracket, and an adjustable mounting bracket. Among them, the circuit component may pass through a through hole at the bottom of the antenna cover for transmitting radio frequency signals; the antenna cover and the antenna bottom cover may be made of polycarbonate material for fixing the transparent radiation module.

Specifically, the side mounting bracket may be the first fixing device and the second fixing device in the above embodiment, and the bottom mounting bracket may be the first bracket in the above embodiment.

[0068] Figure 3 It is a front view of a radiation module of an antenna provided by an embodiment of the present application.

[0069] As Figure 3 shown, the transparent radiation module may include: a transparent area (corresponding to Figure 3 the white part in Figure 3 ) and a power splitter printed circuit board (corresponding to Figure 3 the green part in

[0070] ) There may be 10 transparent antenna elements provided on the transparent area (corresponding to Figure 3 the squares in Figure 3 ), and the transparent antenna elements may be made of polyethylene terephthalate material for receiving and transmitting wireless signals. The power splitter printed circuit board may be made of opaque material, and the power splitter printed circuit board is used to distribute radio frequency signals to the transparent antenna elements or to combine the wireless signals received by the transparent antenna elements.

[0071] Figure 4 It is a schematic diagram of an antenna cover and an antenna bottom cover of an antenna provided by an embodiment of the present application. Among them, Figure 4 (a) in Figure 4 is a schematic diagram of the internal structure of the antenna cover,

[0072] (b) in Figure 4 is a schematic diagram of the internal structure of the antenna bottom cover. Since the transparent radiation module includes an opaque power splitter printed circuit board, the antenna cover and the antenna bottom cover can be added with opaque shielding on the upper and lower sides by means of two-color injection molding. As Figure 4As shown in (a) therein, a rectangular frame (corresponding to the first frame) is provided inside the radome. The first frame and the edge of the radome form a closed groove, and the height of the first frame is lower than the height of the edge of the radome. This closed groove can be used as the above-mentioned opaque shield to prevent incident light from irradiating the power splitter printed circuit board. On the other hand, this closed groove can be used for cable routing to prevent the cable from extending into the transparent area and affecting the transparency effect of the transparent area. As Figure 4 As shown in (b) therein, a raised rectangular frame (corresponding to the second frame) can be provided on the antenna base. The second frame can be used in cooperation with the first frame to fix the transparent area of the radiation module.

[0073] In addition, 8 threaded posts (corresponding to the first threaded posts) can be provided in the central area of the closed groove in the radome for cooperating with the first frame and the second frame to fix the radiation module; 12 threaded posts (corresponding to the second threaded posts) are provided in the area of the closed groove in the radome close to the edge of the radome for realizing the connection between the radome and the antenna bottom cover; four through holes can also be provided at the bottom of the radome for leading out the circuit.

[0074] It should be understood that Figure 4 The number of the threaded posts in the shown closed groove is only an exemplary illustration, and those skilled in the art can increase or decrease the number of the threaded posts in the closed groove according to actual needs.

[0075] Figure 5 is a schematic structural diagram of a bracket provided by an embodiment of the present application.

[0076] In Figure 5 , the corresponding types of each material can be as shown in Table 1 below.

[0079] Optionally, among the materials shown in Table 1 above, 8 M8 hexagon head screws can also be included for connecting the side mounting bracket and the radome.

[0080] After the assembly of each material in Table 1 is completed, the bracket as shown in Figure 6 can be obtained. By adjusting the position of the expansion screw (which can correspond to the first screw) on the slide rail in the bracket shown in Figure 6 , and adjusting the position of the M10 hexagon head screw (which can correspond to the second screw) on the slide rail on the side of the bracket, the radiation direction of the antenna can be adjusted to achieve directional radiation.

[0081] When the antenna is actually installed, as shown in Figure 7 and Figure 8As shown, the radome can be connected to two side mounting brackets through eight M8 hexagon screws, and the two side mounting brackets can be further connected to two side walls (which can correspond to the first side wall and the second side wall) of the adjustable mounting bracket through four M10 hexagon screws. The adjustable mounting bracket is connected to the parapet wall through two expansion screws, and finally the antenna is fixed on the parapet wall.

[0082] The following combines Figures 9 to 13 to analyze the stress performance of each component of the antenna in the environment of a 16-level wind outdoors.

[0083] As Figure 9 shown, the results of the mechanical simulation of the antenna show that for the entire antenna structure, the maximum stress is located at the bending position of the adjustable mounting bracket, and the maximum stress is 117 Mpa.

[0084] As Figure 10 shown, the results of the mechanical simulation of the radome and the antenna bottom cover show that the maximum stress of the radome and the antenna base is 9.45 Mpa, and this value is less than the yield strength of 62 Mpa of the polycarbonate material.

[0085] As Figure 11 shown, the results of the mechanical simulation of the side mounting bracket show that the maximum stress of the side mounting bracket is 86 Mpa, which is less than the yield strength of 252 Mpa of the stainless steel material.

[0086] As Figure 12 shown, the results of the mechanical simulation of the adjustable mounting bracket show that the maximum stress of the adjustable mounting bracket is 117 Mpa, which is less than the yield strength of 252 Mpa of the stainless steel material.

[0087] As Figure 13 shown, the results of the mechanical simulation of the nuts, screws and expansion screws used in the assembly of the antenna show that the maximum stress of the above materials is 70 Mpa, which is less than the yield strength of 252 Mpa of the stainless steel material.

[0088] In summary, combined with Figures 9 to 13 the mechanical simulation results, it can be known that all components of the antenna provided in the embodiment of the present application and the antenna as a whole can be used in the extreme environment of a 16-level wind and meet the requirements of reliability for outdoor use.
