Description

Technical Field

[0001] The present application relates to the field of antenna technology, and in particular to a mounting structure for an antenna and a radome. Background Art

[0002] With the application and development of mobile communication technology, the antenna surface resources are becoming increasingly scarce. The front radiation unit, debugging boundary, debugging isolation strip, conformal support, back phase shifter mounting plate and other components are basically based on the reflector. However, due to the limitation of the reflector size, the layout of the components on the front and back sides often becomes more compact as the number of components increases, and even the layout cannot be arranged, which increases the difficulty of antenna layout. As the components become more compact, it may also cause the antenna circuit and radiation performance to deteriorate more and more seriously.

[0003] For example, when installing a metal isolation strip on a reflector, there are many rivet holes on the isolation strip, and insulation film is required. During the installation process, it is easy to cause a short circuit in the reflector, thereby affecting the intermodulation index. The large number of rivets will also affect the reliability of the entire antenna. On the production line, due to the limitations of the process and the high degree of integration of the reflector in the antenna, the entire production process on the reflector basically does not have the conditions for parallel work. The production time of a single antenna is long and the cost is high. Summary of the Invention

[0004] In order to solve the above technical problems or at least partially solve the above technical problems, the present application provides a mounting structure for an antenna and a radome.

[0006] In some embodiments, the sliding portion is disposed on at least one end or at least one side of the boundary device.

[0007] In some embodiments, the fixing mechanism includes a first fixing member, the first fixing member includes two L-shaped first fixing plates arranged opposite to each other, a first sliding groove is formed between the two first fixing plates, and the boundary device is slidably connected to the first sliding groove.

[0008] In some embodiments, the fixing mechanism includes a second fixing member, the second fixing member includes two T-shaped second fixing plates arranged opposite to each other, a second sliding groove is formed between the two second fixing plates, and a third sliding groove is formed on the opposite sides of the two second fixing plates.

[0009] In some embodiments, the fixing mechanism includes a sliding groove formed on the inner wall of the antenna cover, and the boundary device is provided with a sliding portion that slidably cooperates with the sliding groove.

[0010] In some embodiments, there are one or more boundary devices, and the boundary devices are arranged corresponding to at least one side wall of the antenna cover; when there are multiple boundary devices, the multiple boundary devices do not interfere with each other.

DETAILED DESCRIPTION

[0031] In order to more clearly understand the above-mentioned objectives, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application can also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present application, not all of the embodiments.

[0033] like Figure 1 As shown, in the traditional antenna structure, the radiation unit and the boundary device are basically installed on the reflector. Due to the limitation of the size of the reflector, the layout of the components on the front and back sides tends to become more compact as the number of components increases, and even the layout cannot be completed.

[0034] In order to solve the problem that there are too many components installed on the reflector, which leads to the continuous deterioration of the antenna circuit and radiation performance, the embodiment of the present application provides an installation structure for the antenna and the antenna cover, which transfers at least part of the components originally installed on the reflector to the antenna cover, effectively utilizing the installation space of the antenna cover, and at the same time solves the problem that there are too many components installed on the reflector, which makes it impossible to layout.

[0035] like Figures 2 to 11 As shown, an embodiment of the present application provides an installation structure of an antenna and an antenna cover 1, including an antenna cover 1 and an antenna arranged inside the antenna cover 1, the antenna including a reflector 2, a radiation unit 21 and a boundary device 3, the radiation component is installed on the reflector 2, a fixing mechanism is provided on the inner wall of the antenna cover 1, the boundary device 3 is installed on the antenna cover 1 through the fixing mechanism, and there is no connection between the boundary device 3 and the reflector 2.

[0036] Specifically, the radome 1 can have any shape. The radome 1 is a closed structure, and the antenna is disposed within the radome 1 to prevent exposure to air. The radome 1 thus provides protection for the antenna. In some embodiments of the present application, the radome 1 includes a radome 1 body and a cover. The radome 1 body is a cylindrical structure with an approximately rectangular cross-section. After installation, the cover seals both ends of the radome 1 body, providing a sealed connection between the cover and the radome 1 body. The reflector 2 is fixed within the radome 1 body, with the front surface of the reflector 2 facing the top plate of the radome 1 body and the back surface of the reflector 2 facing the bottom plate of the radome 1 body.

[0037] The antenna and radome 1 mounting structure provided in the embodiments of the present application at least partially mounts the boundary device 3, originally mounted on the reflector 2, onto the radome 1. This solves the problem of numerous components mounted on the reflector 2, which makes it difficult to arrange the components on the reflector 2. This effectively utilizes the mounting space of the radome 1, shifting the mounting location of the boundary device 3, and resolving the layout difficulties caused by the large number of boundary devices 3 installed on the reflector 2, thereby reducing the degradation of the antenna circuit and radiation performance.

[0038] The boundary device 3 is installed on the antenna cover 1 through a fixing mechanism on the antenna cover 1. Specifically, there are various forms of the fixing mechanism. For example, the fixing mechanism can be fasteners such as screws and bolts, or it can be tape, clips or slides. In order to ensure the sealing performance of the antenna cover 1, when fasteners such as screws or bolts are used to install the boundary device 3 on the antenna cover 1, the position where the threaded hole is opened on the antenna cover 1 needs to be sealed.

[0039] Furthermore, in some embodiments of the present application, the fixing mechanism includes a slide groove formed on the inner wall of the radome 1, and the boundary device 3 is provided with a sliding portion that cooperates with the slide groove. The slide groove and the sliding portion cooperate to assemble the boundary device 3 with the radome 1, and the boundary device 3 can be installed and removed by pulling, which is convenient. Furthermore, the provision of the slide groove on the inner wall of the radome 1 does not damage the overall structure of the radome 1, nor does it damage the strength and sealing performance of the radome 1. Therefore, there is no need to further strengthen the strength of the radome 1 or reseal the radome 1.

[0040] Specifically, in some embodiments of the present application, the fixing mechanism includes a first fixing member 12, the first fixing member 12 includes two L-shaped first fixing plates arranged opposite to each other, a first sliding groove is formed between the two first fixing plates, and the boundary device 3 can be slidably connected to the first sliding groove.

[0041] Specifically, the edge of the boundary device 3 can be bent to form the sliding portion, or a separate T-shaped connecting plate can be provided on the side of the boundary device 3 to form the sliding portion.

[0042] The two L-shaped first fixing plates are arranged opposite to each other with a gap therebetween. The width of the gap is adapted to the thickness of the boundary device 3 to be installed. The sliding portion is inserted into the first slide groove from one end of the first slide groove and will not fall out of the gap formed between the two L-shaped first fixing plates, thereby ensuring stable movement of the boundary device 3 during the installation process.

[0043] For example, in order to prevent the sliding portion of the boundary device 3 from falling out of the gap between the two L-shaped first fixing plates, the sliding portion and the body of the boundary device 3 are usually bent to form a certain angle. In some preferred embodiments, the sliding portion and the body of the boundary device 3 form a 90° angle.

[0044] Furthermore, in some embodiments of the present application, the fixing mechanism includes a second fixing member 11, the second fixing member 11 includes two T-shaped second fixing plates arranged opposite to each other, a second slide groove is formed between the two second fixing plates, and a third slide groove is formed on the opposite sides of the two second fixing plates.

[0045] Specifically, the T-shaped second fixing plate specifically includes a first connecting plate and a second connecting plate. The first connecting plate is connected to the side wall of the antenna cover 1 in a direction perpendicular to the side wall of the antenna cover 1, and the second connecting plate is connected to the end of the first connecting plate away from the side wall of the antenna cover 1 in a direction parallel to the side wall of the antenna cover 1. The first connecting plate and the second connecting plate are arranged in a T shape, that is, the middle part of the second connecting plate is connected to the end of the first connecting plate, and a second slide groove is formed between the two second fixing plates, and a third slide groove is formed on the outside of the second fixed plate, wherein the structure of the second slide groove is similar to that of the first slide groove, and the third slide groove is a single-sided groove, and two third slide grooves need to be used in combination to limit the boundary device 3.

[0046] The second fixing member 11 and the first fixing member 12 can be used in combination or separately, and can be freely selected according to the number and position of the boundary devices 3 to be installed.

[0047] Furthermore, in some embodiments of the present application, the number of boundary devices 3 is one or more, and the boundary device 3 is arranged corresponding to at least one side wall of the antenna cover 1. Specifically, the boundary device 3 can be arranged relative to at least one of the top plate, side plate and bottom plate of the antenna cover 1. Exemplarily, when the boundary device is arranged relative to the top plate of the antenna cover 1, the boundary device 3 can be slidably matched with the slide groove on the top plate of the antenna cover 1, or can be slidably matched with the slide groove on the side plate of the antenna cover 1, or can be matched with the slide groove on the bottom plate of the antenna cover 1. The form of the slide groove can be any one of the above-mentioned first slide groove, second slide groove or third slide groove.

[0048] When there are multiple boundary devices 3, the multiple boundary devices 3 do not interfere with each other. The setting positions of different boundary devices 3 and the forms of the sliding parts and the forms of the sliding grooves of different boundary devices 3 can be set to install different boundary devices 3 at different positions on the antenna cover 1. After the installation is completed, the different boundary devices 3 will not interfere with each other in position and will not affect each other in function.

[0049] Furthermore, in some embodiments of the present application, a sliding portion is provided on at least one end or at least one side of the boundary device 3. For example, the end of the boundary device 3 may be bent to form a sliding portion that slides in conjunction with the slide groove, or a T-shaped sliding portion may be provided on one side of the boundary device 3 to slide in conjunction with the slide groove.

[0050] Specifically, the boundary device 3 can be at least one of an isolation strip 4, an isolation sheet 5, a side panel, a side strip, a guide sheet, a back panel 7, a hard circuit board, an epoxy board, and a hollow structure with a cavity. In the traditional structure, the isolation strip 4, the isolation sheet 5, the side panel, the side strip, the guide sheet, the hard circuit board, and the epoxy board are generally installed on the reflector 2, and the back panel 7 is installed on the side of the reflector 2 or is attached to the bottom plate of the antenna cover 1 in the form of metal paper and is arranged opposite to the back of the reflector 2. The electromagnetic waves on the back of the reflector 2 are reflected through the back panel 7, and the emission path of the electromagnetic waves on the back of the reflector 2 is changed to prevent the electromagnetic waves from being lost from the bottom plate of the antenna cover 1. In some embodiments of the present application, the back panel 7 is in the form of a metal plate, and the two ends of the back panel 7 are bent, and a slide groove is set on the side panel of the antenna cover 1. The two ends of the back panel 7 cooperate with the slide groove respectively to realize the back panel. 7 is assembled with the antenna cover 1, and the back plate 7 is installed on the antenna cover 1, which can achieve the same technical effect as the original back plate 7; when the boundary device 3 is a hollow structure, the hollow structure and the inner wall of the antenna cover 1 are slidably matched through the slide groove to realize the assembly of the hollow structure and the antenna cover 1. The hollow structure has a plurality of cavities, and the plurality of cavities can be distributed regularly or irregularly. By arranging the hollow structure on the antenna cover 1, the equivalent dielectric constant and the equivalent loss tangent value of the antenna cover 1 can be changed. The hollow structure is generally installed on the top plate of the antenna cover 1, covering the entire area or part of the area of the top plate, and the number and position of the hollow structures to be installed can be selected as appropriate.

[0051] Furthermore, in some embodiments of the present application, the projection of the boundary device 3 on the side wall of the radome 1 covers at least a portion of the inner wall of the radome 1. As described in the above embodiments, when the boundary device 3 is a structure such as a spacer strip 4, a spacer plate 5, a side panel, a side strip, or a guide plate, it is generally small in size, and its projection on the side wall of the radome 1 only covers a portion of the side wall of the radome 1. When the boundary device 3 is a hollow structure, the size, number, and position of the hollow structures can be set according to the antenna parameters, and the projection area and projection range of the hollow structures on the side wall of the radome 1 can be selected. When the boundary device 3 is a backplate 7, the backplate 7 is generally larger than the reflector 2, and the projection of the reflector 2 on the bottom plate of the radome 1 falls within the projection of the backplate 7 on the bottom plate of the radome 1.

[0052] Furthermore, in some embodiments of the present application, the boundary device 3 is made of metal and / or non-metal. When the boundary device 3 is a structure such as a spacer strip 4 or a spacer sheet 5, the boundary device 3 is made of non-metal. When the boundary device 3 is a rigid circuit board, the boundary device 3 is made of both metal and non-metal. When the boundary device 3 is a backplane 7, the boundary device 3 is made of metal. In other words, the slide grooves on the radome 1 can secure both metal and non-metal components.

[0053] Due to the freedom of position, quantity and combination of the fixing mechanism on the inner wall of the antenna cover 1, the metal or non-metal boundary device 3 carrying the adjustable antenna index fixed thereon also has freedom of position, quantity and combination inside the antenna cover 1.

[0054] Generally speaking, there are two ways to install the metal or non-metal boundary device 3 for adjusting antenna parameters: one is to directly install the boundary device 3 in the corresponding mounting holes on the reflector 2 using fasteners such as rivets or screws; the other is to install it through a medium, for example, first installing the boundary device 3 on a support column, and then fixing the support column to the reflector 2, or installing the boundary device 3 on a plastic guide support, and then installing the guide support on the radiation unit 21, and the radiation unit 21 is installed on the reflector 2. Both methods involve direct or indirect contact with the reflector 2, which reduces the number of parallel processes during the assembly process, and thus the assembly efficiency cannot be improved. At the same time, the load on the reflector 2 is increased, which reduces the overall structural reliability of the reflector 2. At the same time, the above two methods also have certain limitations. These two installation methods often require that the mounting holes of the boundary device and the reflector 2, or the mounting holes of the medium, are within the vertical three-dimensional projection space of the radiation surface without interference from other components in order to be properly installed.

[0055] The present disclosure provides a third installation method, that is, a metal or non-metal boundary device 3 is installed on the antenna cover 1 through a fixing mechanism, which reduces the pressure borne by the reflector 2. At the same time, these metal or non-metal boundary devices 3 are not in direct contact with the reflector 2. Compared with the two conventional installation methods, the electrical indicators of the antenna will be better. Since the boundary device 3 also has freedom in position, quantity, and combination inside the antenna cover 1, the existing installation structure of the boundary device 3 can be equivalently realized under most conditions through different arrangements and combinations of the boundary device 3 on the antenna cover 1, thereby achieving equivalent electrical functions. At the same time, the production process can also be optimized. The metal or non-metal boundary device 3 previously installed on the reflector 2 can be installed on the antenna cover 1 in advance, which reduces the serial processes in the final assembly process to a certain extent, increases the parallel processes, and thus improves the assembly production efficiency.

[0056] The installation structure of the antenna and the antenna cover 1 in the present application will be explained below through multiple specific embodiments of the present application.

[0057] like Figure 1 In the conventional radome boundary device installation diagram shown, the first boundary device 23 is first fixed to the support structure 22, and the support structure 22 is fixed to the reflector 2, or the second boundary device 24 is directly connected to the reflector.

[0058] like Figure 1As shown, in the first embodiment of the present disclosure, there are two second fixing members 11 at the top of the antenna cover 1, each of which is fixed with a boundary device 3 (with Figure 1 The first boundary device has the same function as the second boundary device), this boundary device is located above the radiation unit 21 and can adjust the antenna indicators. It can be clearly seen that the single boundary device 3 on the top of the antenna cover has no direct contact with the reflector 2 and the radiation unit 21.

[0059] contrast Figure 1 and Figure 2 It can be clearly seen that since the single boundary device 3 on the top of the radome has no direct contact with the reflector, Figure 2 The boundary device 3 on top of the radome realizes Figure 1 The first boundary device 23 achieves the same or even better debugging results as the second boundary device 24, while also reducing the number of materials required to be installed on the reflector, improving the overall reliability of the antenna. Furthermore, during the production installation process, the boundary device 3 on top of the radome can be pre-installed on the radome 1, completely independent of and parallel to the components installed on the reflector 2, improving overall assembly efficiency and saving labor.

The second cross-type boundary device 8 can also be a hollow structure that changes the equivalent dielectric constant and the equivalent loss tangent value of the radome; Figure 9 The second cross-border device 8 and the third cross-border device 9 are fixedly connected on the top of the radome 1 through two second fixing members 11; Figure 10 To fix two boundary devices 3 and two isolation strips 4 on the sides and top of the radome 1 through two second fixing members 11 and a first fixing member 12; Figure 11Two boundary devices 3 and two isolation strips 4 , a back plate 7 and a cross-type boundary device 8 are fixedly connected on the side and top of the radome 1 through two second fixing members 11 and the first fixing member.
