[0002] This application claims priority to Chinese Patent Application No. 202311751798.9, filed on December 18, 2023, with the State Intellectual Property Office of the People's Republic of China, entitled "An Antenna and Base Station", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of communication technology, and in particular to an antenna and a base station. Background Technology

[0004] With the development of mobile communication, the usage rate of mobile terminals is increasing, and the network coverage of mobile cellular networks is crucial to mobile communication. A key component of mobile cellular networks is the antenna. Typically, the antenna's gain is positively correlated with its physical size; that is, to achieve higher gain, the antenna needs to be larger.

[0005] However, since antennas are typically mounted on poles or towers at high locations, the larger the antenna, the greater the wind resistance it experiences. This results in increased drag, affecting the antenna's structural reliability and consequently its lifespan. Improving antenna reliability requires reinforcing the antenna and its mounting structure, but this significantly increases installation costs. Therefore, finding a way to reduce wind resistance while ensuring the antenna meets size requirements, thus achieving a more reliable structure, has become a pressing problem for those skilled in the art.

[0006] Summary of the Invention

[0007] This application provides an antenna and a base station to reduce the antenna's wind resistance, thereby improving the antenna's structural reliability.

[0008] Firstly, this application provides an antenna comprising a mounting structure and at least two antenna subarrays. Each antenna subarray includes an radome, a reflector, and a radiating element. The radiating element is located on one side of the reflector and is connected to it. The reflector and radiating element are housed within the radome. The radome includes a cover and two end caps, each located at one end of the cover and sealing one end of the cover, thus protecting the reflector and radiating elements. Furthermore, the radome is an integral structure, effectively improving the structural reliability of the antenna subarrays. The mounting structure is located outside the radome of each antenna subarray. At least one of the radomes or reflectors in each antenna subarray is connected to the mounting structure, and any two adjacent antenna subarrays are spaced apart. The antenna provided in this application has ventilation gaps between any two adjacent antenna subarrays, which helps reduce wind resistance and thus improves the structural reliability of the antenna.

[0009] In one possible implementation of this application, the reflector is a continuous plate structure, which effectively improves the reflector's performance in reflecting radio frequency signals radiated by the radiating element. Alternatively, the reflector can be a perforated plate structure, allowing the reflector to have frequency selectivity by adjusting the perforation pattern. This enables the reflector to reflect and transmit radio frequency signals of specific frequencies, allowing the antenna to be stacked with other antennas. This enables the antenna to be installed on the same antenna plane for different operating frequency bands, allowing for antenna upgrades and expansions without changing the existing antenna. This helps reduce antenna upgrade and installation costs.

[0010] Secondly, this application also provides an antenna, which includes a mounting structure and at least two antenna subarrays. Each antenna subarray includes an radome, a reflector, and a radiating element. The radiating element is located on one side of the reflector and is connected to the reflector. The reflector and the radiating element are housed within the radome. The radome includes a cover and two end caps, which are respectively located at two ends of the cover, each end cap sealing one end of the cover to protect the reflector and radiating elements. The reflector is connected to the inner wall of the radome and has a perforated plate structure. The mounting structure is located outside the radome of each antenna subarray. At least one of the radome or reflector in each antenna subarray is connected to the mounting structure, and any two adjacent antenna subarrays are spaced apart. The antenna provided in this application has a ventilation gap between any two adjacent antenna subarrays, which helps reduce wind resistance and improves the structural reliability of the antenna. Furthermore, since the reflector has a perforated plate structure, the perforation pattern of the reflector can be adjusted to make it frequency selective. This allows the reflector to reflect and transmit radio frequency signals of a specific frequency, enabling the antenna to be stacked with other antennas. This allows for the co-mounting of antennas with different operating frequency bands on the same antenna surface. It also allows for antenna upgrades and expansions without changing the existing antenna, which helps reduce antenna upgrade and installation costs.

[0011] In the antennas provided in the first and second aspects of this application, the reflector includes at least two sub-reflector layers, which are stacked along the side facing away from the radiating element, and any two adjacent sub-reflector layers are spaced apart. By adopting the above design, the reflector's reflection performance of the radio frequency signal radiated by the radiating element can be improved through the combined design of at least two sub-reflector layers. Furthermore, setting the reflector as having at least two sub-reflector layers also facilitates a reduction in the overall width of the reflector, thereby reducing the width of the antenna subarray. This allows for an increase in the spacing between two adjacent antenna subarrays without changing the overall antenna size, or a reduction in antenna size while maintaining antenna performance, thus helping to reduce antenna wind resistance.

[0012] As described above, when the reflector is connected to the inner wall of the radome, and the reflector comprises at least two sub-reflector layers, each sub-reflector layer can be connected to the inner wall of the radome, thus improving the reliability of the connection between the reflector and the radome. Alternatively, at least one sub-reflector layer can be connected to the inner wall of the radome, with adjacent sub-reflector layers connected by rigid supports. This allows for the connection of at least one sub-reflector layer to the inner wall of the radome after connecting adjacent sub-reflector layers to the rigid supports, effectively improving the assembly efficiency of the reflector and the radome.

[0013] To improve the reflection performance of the reflector on the radio frequency signals radiated by the radiating element, in one possible implementation of this application, at least one sub-reflector layer of the reflector may include two oppositely arranged bent portions, each bent along the direction from the reflector to the radiating element. This design of the sub-reflector layer also facilitates a reduction in the overall width of the reflector, thereby reducing the width of the antenna subarray.

[0014] In addition, each antenna subarray includes two metal baffles, which are positioned opposite each other and connected to the inner wall of the radome. The radiating element is located between the two metal baffles, and the arrangement direction of the two bends in each reflector layer is the same as the arrangement direction of the two metal baffles. In this way, the two metal baffles can reflect the radio frequency signal radiated by the radiating element, which helps improve the front-to-back ratio of the antenna subarray, thereby improving its signal radiation performance.

[0015] In one possible implementation of the first and second aspects of this application, the radiating element includes a first radiating portion and a second radiating portion connected together, the first radiating portion and the second radiating portion being arranged at a predetermined angle, the first radiating portion being connected to a reflector, and the second radiating portion being bent from the first radiating portion toward the reflector. In this application, the radiating element of the antenna subarray is designed using the above-mentioned two-part bending method, which can effectively reduce the area occupied by the radiating element on the reflector, which is beneficial to reducing the size of the reflector, thereby benefiting the reduction of the width of the antenna subarray.

[0016] In addition, each antenna subarray includes a band-stop reactor layer, which is a perforated metal layer. The radiating element is located between the band-stop reactor layer and the reflector, and the band-stop reactor layer is connected to the inner wall of the radome. In this way, the radio frequency signal radiated by the radiating element can be radiated through the perforated portion of the band-stop reactor layer. By rationally designing the perforation pattern of the band-stop reactor layer, the bandwidth of the radio frequency signal radiated by the radiating element can be adjusted, thereby improving the signal radiation performance of the antenna subarray.

[0017] In this application, to improve the bandwidth adjustment effect of the band-stop reactive layer on the radiating element's radiating radio frequency signal, the projection of the band-stop reactive layer on the reflector covers the projection of the radiating element on the reflector. This improves the electrical performance of the antenna subarray.

[0018] In one possible implementation of the first and second aspects of this application, the cross-sectional shape of the radome can be elliptical, circular, or rounded rectangular, etc. In addition, the radome can be a cylindrical structure integrally formed by extrusion molding or other processes. This can ensure the structural reliability of the radome while also reducing the width of the radome, thereby reducing the wind resistance of the antenna.

[0019] Furthermore, the spacing between any two adjacent antenna subarrays is equal. This reduces wind resistance while still meeting the antenna array performance requirements.

[0020] In this application, the mounting structure can be configured in various ways depending on the application scenario of the antenna. For example, in one possible implementation of the first and second aspects, the mounting structure is a beam structure. Furthermore, the antenna includes at least two mounting structures spaced apart, with at least one of the radomes or reflectors of each antenna subarray connected to each mounting structure. This allows for a reliable connection between at least two antenna subarrays via at least two mounting structures, which improves the structural reliability of the antenna.

[0021] In another possible implementation of the first and second aspects, the mounting structure is a bent structure, in which case the antenna also includes at least two mounting structures spaced apart, and at least one of the radomes or reflectors of each antenna subarray is connected to each mounting structure. This allows at least two antenna subarrays to be reliably connected through at least two mounting structures, which helps to improve the structural reliability of the antenna.

[0022] The bending shape of the mounting structure mentioned above can be U-shaped, V-shaped, arc-shaped, or triangular, and its specific design can be tailored to the specific application scenario of the antenna.

[0023] In another possible implementation of the first and second aspects, the mounting structure includes a first rotating part and a second rotating part, the first rotating part and the second rotating part being hinged together. At least one of the radomes or reflectors of at least one of the at least two antenna subarrays is connected to the first rotating part, and at least one of the radomes or reflectors of at least one of the at least two antenna subarrays is connected to the second rotating part. This allows for adjustment of the overall antenna shape through the relative rotation of the first rotating part and the second rotating part, enabling the antenna to meet the requirements of different application scenarios and thus expanding the antenna's applicability.

[0024] Specifically, when connecting the mounting structure to the antenna subarray, in one possible implementation of the first and second aspects of this application, the mounting structure can be integrally formed with the end caps located on the same side of at least two antenna subarrays. This simplifies the antenna structure and improves the antenna assembly efficiency.

[0025] In addition to the above structure, the antenna provided in this application also includes a radio frequency (RF) active module. The RF active module is located outside the radome of each antenna subarray. The RF active module is connected to at least one of the radomes or reflectors of each antenna subarray, and is electrically connected to the radiating elements of each antenna subarray. This improves the convenience of electrically connecting the RF active module to each radiating element and saves on the connection cables between the RF active module and the radiating elements, thereby reducing antenna costs.

[0026] In one possible implementation of the first and second aspects of this application, the antenna includes at least two radio frequency (RF) active modules located outside the radome of each antenna subarray. Each RF active module is connected to at least one of the radomes or reflectors of at least one antenna subarray, and each RF active module is electrically connected to a radiating element of at least one antenna subarray. This effectively improves the flexibility of RF active module placement and the flexibility of connecting the RF active modules to the radiating elements of at least two antenna subarrays.

[0027] Furthermore, when the antenna includes at least two active radio frequency (RF) modules, these modules can be configured in a one-to-one correspondence with at least two antenna subarrays. Each RF active module is located outside the radome of a corresponding antenna subarray, and each RF active module is electrically connected to the radiating element of a corresponding antenna subarray. This design effectively enhances the flexibility of the overall antenna form factor design, making the antenna applicable to a wider range of scenarios.

[0028] Thirdly, this application also provides a base station, which includes a support frame and an antenna as described in the first or second aspect, with the antenna connected to the support frame. Because the antenna of this base station has low wind resistance, its structural reliability is high, which helps to improve the structural reliability and signal radiation performance of the base station.

[0052] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein. The same reference numerals in the figures denote the same or similar structures, and therefore repeated descriptions of them will be omitted. The terms expressing position and direction described in the embodiments of this application are illustrative based on the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this application. The accompanying drawings of the embodiments of this application are only for illustrating relative positional relationships and do not represent actual scale.

[0053] It should be noted that specific details are set forth in the following description to facilitate understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0054] To facilitate understanding of the antenna and base station provided in this application, their application scenarios are first introduced below. Figure 1 illustrates an exemplary system architecture applicable to an embodiment of this application. As shown in Figure 1, this system architecture may include a base station 1000 and a terminal 2000. Wireless communication can be achieved between the base station 1000 and the terminal 2000. The base station 1000 can also be referred to as an access network device, which may be located in a base station subsystem (BBS), a UMTS terrestrial radio access network (UTRAN), or an evolved universal terrestrial radio access network (E-UTRAN), and is used for cell coverage to enable communication between the terminal device and the wireless network. Specifically, base station 1000 can be a base transceiver station (BTS) in a Global System for Mobile Communication (GSM) or Code Division Multiple Access (CDMA) system, a Node B (NB) in a Wideband Code Division Multiple Access (WCDMA) system, an Evolutionary Node B (eNB or eNodeB) in a Long Term Evolution (LTE) system, or a radio controller in a cloud radio access network (CRAN) scenario. Alternatively, base station 1000 can also be a relay station, access point, vehicle-mounted equipment, wearable device, g node (gNodeB or gNB) in a new radio (NR) system, or access network equipment in a future evolved network, etc., and the embodiments in this application are not limited to these.

[0055] Base station 1000 is equipped with antenna 100 to transmit signals in space. Figure 2 shows a schematic diagram of an application scenario of antenna 100 equipped with base station 1000 as shown in Figure 1. Figure 2 shows the support frame 200 and antenna 100, etc. The support frame 200 can be, but is not limited to, a pole or tower, etc. The antenna 100 is connected to the support frame 200, such as a pole or tower, to facilitate the reception or transmission of signals by the antenna 100. The radome 10 has good electromagnetic wave penetration characteristics in terms of electrical performance and can withstand the influence of harsh external environments in terms of mechanical performance, thereby protecting the antenna system from the influence of the external environment.

[0056] Currently, with the increase in antenna gain and aperture, their structural size is also becoming larger. Furthermore, with the improvement of communication speed and bandwidth, antennas often integrate multiple-input multiple-output (MIMO) technology, meaning that multiple rows of radiating elements for signal transmission or reception are integrated into a single antenna. This integrated design also leads to an increase in antenna size. In addition, antenna size is also related to the operating frequency band; the lower the operating frequency, the larger the antenna needs to be. As mentioned above regarding base stations, antennas are usually mounted high on support structures such as poles or towers. The larger the antenna, the greater the wind resistance it experiences, and the more site space it occupies.

[0057] In view of this, the antenna provided in this application, by dividing itself into multiple antenna subarrays and spacing them apart to form ventilation zones, effectively reduces the antenna's wind resistance while meeting size design requirements. This improves the antenna's structural reliability and extends its service life. To facilitate understanding of the technical solution of this application, the antenna provided in this application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0058] Referring to Figure 3, which is a schematic diagram of an antenna 100 provided in an embodiment of this application, the antenna 100 includes at least two antenna subarrays 1001 and a mounting structure 1002. The at least two antenna subarrays 1001 are connected by the mounting structure 1002 to form an antenna array.

[0059] Each antenna subarray 1001 includes an antenna radome 10. As shown in Figure 3, the antenna radome 10 includes a radome body 1 and two end caps 2. The two end caps 2 are respectively disposed at the two ends of the radome body 1, and each end cap 2 blocks one end of the radome body 1, thereby forming a closed cavity, so that the antenna radome 10 can protect the components housed in its cavity from dust and water.

[0060] Referring to Figure 4, which is a cross-sectional view (AA) of the antenna 100 shown in Figure 3, in this embodiment, the radome 10 can be an integral structure, that is, the radome 1 can be prepared by integral molding processes such as extrusion, which is beneficial to improving the structural reliability of the radome 10.

[0061] In some other possible embodiments of this application, the radome 10 can also be an assembly structure, that is, the radome 1 can be a structure obtained by assembling multiple components, so as to improve the flexibility of the radome 10.

[0062] In addition, in this application, the cover 1 can be a cylindrical structure, and the cross-sectional shape of the cover 1 is not limited to the rounded rectangle shown in Figure 5. It can also be a circle, an ellipse, or a teardrop shape, etc., which will not be listed here.

[0063] Referring again to Figure 4, each antenna subarray 1001 further includes a reflector 40 and a radiating element 30, which are housed in the radome 10. The radiating element 30 is located on one side of the reflector 40 and is connected to the reflector 40. Additionally, the reflector 40 can be connected to the inner wall of the radome 10, and the connection method can be, but is not limited to, snap-fit, adhesive, or threaded connection, so that the reflector 40 can reliably support the radiating element 30.

[0064] In this embodiment, the radiating element 30 can also be called an antenna element, vibrator, etc. The radiating element 30 is a unit constituting the basic structure of the antenna array, and it can effectively radiate or receive antenna signals. Different radiating elements 30 can have the same or different frequencies. The reflector 40 can also be called a base plate, antenna panel, or metal reflective surface, etc. The reflector 40 can reflect and focus the received signal onto the receiving point. The radiating element 30 is placed on one side of the reflector 40, which not only greatly enhances the signal reception or transmission capability but also blocks and shields interference signals from the back of the reflector 40. In this application, the back of the reflector 40 refers to the side of the reflector 40 opposite to the side where the radiating element 30 is located.

[0065] In this embodiment of the application, as shown in Figures 3 and 4, the mounting structure 1002 is located outside the radome 10 of each antenna subarray 1001. Therefore, when connecting each antenna subarray 1001 to the mounting structure 1002, at least one of the radome 10 or the reflector 40 of each antenna subarray 1001 can be connected to the mounting structure 1002. Specifically, the cover 1 of the radome 10 of the antenna subarray 1001 can be connected to the mounting structure 1002 using fasteners such as bolts, or the reflector 40 of the antenna subarray 1001 can be connected to the mounting structure 1002 using fasteners passing through the radome 10. Alternatively, both the radome 10 and the reflector 40 of the antenna can be connected to the mounting structure 1002.

[0066] In addition, referring to Figures 3 and 4, in the antenna 100 provided in this application, any two adjacent antenna subarrays 1001 are spaced apart, which allows for ventilation gaps between any two adjacent antenna subarrays 1001, thereby helping to reduce the wind resistance of the antenna 100 and improve the structural reliability of the antenna 100.

[0067] It is worth mentioning that this application does not limit the spacing between two adjacent antenna subarrays 1001. For example, in one possible embodiment, the spacing between any two adjacent antenna subarrays 1001 can be equal to meet the array performance requirements such as the electrical and physical performance of the antenna 100.

[0068] As can be understood from the above description of the reflector 40 and radiating element 30 of the antenna subarray 1001, in each antenna subarray 1001, in order to improve the reflection effect of the reflector 40 on the radiating signal of the radiating element 30, the end of the reflector 40 can be made to abut against the inner sidewall of the radome 10, so that the area of ​​the reflector 40 is larger. In addition, the reflector 40 can also be a continuous plate structure to improve its reflection performance. Increasing the area of ​​the reflector 40 and setting the reflector 40 as a continuous plate structure can effectively ensure the front-to-back ratio performance of the antenna subarray 1001. For ease of description in this application, the direction from the reflector 40 to the radiating element 30 can be defined as the front of the antenna subarray 1001, and the direction from the radiating element 30 to the reflector 40 can be defined as the rear of the antenna subarray 1001. Based on this, it can be understood that the front-to-back ratio performance of the antenna subarray 1001 refers to the ratio of the energy radiated forward by the antenna subarray 1001 to the energy radiated backward by the antenna subarray 1001. The larger this ratio is, the smaller the energy radiated backward by the antenna subarray 1001, and the smaller its impact on other antennas located behind the antenna subarray 1001.

[0069] In the antenna 100 provided in this application, the reflector 40 of the antenna subarray 1001 can be configured as a continuous plate structure as described above, or in other possible forms. For example, referring to Figure 5, which is a schematic diagram of a reflector 40 provided in an embodiment of this application, the reflector 40 shown in Figure 5 is a perforated plate structure. The perforation pattern 401 of the reflector 40 can be specifically set according to the wavelength of the radio frequency signal in the operating frequency band of the antenna subarray 1001. For example, it can be a periodic, regular grid pattern, or an aperiodic, irregular pattern, to ensure that the antenna subarray 1001 has a high front-to-back ratio performance.

[0070] In addition, the hollow portion of the hollow pattern 401 of the reflector 40 shown in Figure 5 can also be filled with an insulating medium, such as plastic, which can help improve the front-to-back ratio performance of the antenna subarray 1001.

[0071] Since a base station typically includes multiple antennas 100 operating at different frequency bands, each antenna 100 usually needs to be installed on a separate rooftop, which limits the number of antennas 100 that can be installed in the base station. As described above regarding the reflector 40 of the antenna 100 provided in this application, when the reflector 40 is a perforated plate structure, the perforation pattern 401 of the reflector 40 can be adjusted to make the reflector 40 frequency selective, allowing it to reflect and transmit radio frequency signals of a specific frequency. Based on this, in this embodiment, the perforation pattern 401 of the reflector 40 can also take into account the wavelengths of radio frequency signals in other operating frequency bands, allowing the antenna 100 provided in this application to be stacked with antennas of other operating frequency bands. For example, refer to Figure 6, which is a schematic diagram of the structure of the antenna 100 and another antenna 100a stacked in an embodiment of this application. In Figure 6, another antenna 100a is located behind the antenna 100 provided in this application. Since the reflector 40 of the antenna subarray 1001 of the antenna 100 provided in this application has a hollow plate structure, and since any two adjacent antenna subarrays 1001 are spaced apart, the antenna 100 provided in this application can almost not obstruct the radio frequency signals radiated by the other antenna 100a located behind it within a specific frequency band, so that the other antenna 100a located behind it can work normally. This allows antennas with different operating frequency bands to be installed on the same roof surface, which can upgrade and expand the antenna without changing the existing antenna. This is beneficial to reducing the upgrade cost of the antenna and the installation cost of the antenna.

[0072] It is worth mentioning that in the structure shown in Figure 6, the specific arrangement of the other antenna 100a is not limited; it can be a conventional antenna or the antenna provided in this application. Furthermore, Figure 6 only shows the case of two antennas stacked together. In some possible embodiments, the stacking of three or more antennas can be achieved through the design of the perforated pattern on the reflector.

[0073] In the above embodiments of this application, the reflector 40 is described as a single-layer structure. However, in this application, the reflector 40 can also be a multi-layer structure. For specific implementation, please refer to Figure 7, which is another cross-sectional view of the antenna subarray 1001 provided in this application, which can be used to illustrate another structure of the reflector 40. The reflector 40 shown in Figure 7 includes at least two sub-reflector layers, which are stacked along the side away from the radiating element 30, and any two adjacent sub-reflector layers are spaced apart.

[0074] Referring again to Figure 7, taking the reflector 40, which includes sub-reflector layers 402a and 402b, as an example, the sub-reflector layers 402a and 402b are stacked along the direction away from the radiating element 30, and adjacent sub-reflector layers 402a and 402b are spaced apart. With this design, the reflector 40 can improve its reflection performance of the radio frequency signals radiated by the radiating element 30 through the combined design of at least two sub-reflector layers. Furthermore, setting the reflector 40 to at least two sub-reflector layers also helps to reduce the overall width of the reflector 40, thereby reducing the width of the antenna subarray 1001. This allows for an increase in the spacing between adjacent antenna subarrays 1001 without changing the overall size of the antenna 100, or a reduction in the size of the antenna 100 while maintaining its performance, thus helping to reduce the wind resistance of the antenna 100.

[0075] Additionally, as shown in Figure 7, each sub-reflector layer of the reflector 40 is connected to the inner wall of the radome 10, and the connection method can be, but is not limited to, snap-fit ​​or adhesive bonding. Alternatively, in the antenna sub-array 1001 shown in Figure 8, the sub-reflector layer 402b is connected to the inner wall of the radome 10, and the sub-reflector layer 402b and the adjacent sub-reflector layer 402a are connected by a rigid support member 70. The connection method between the sub-reflector layer 402a and the sub-reflector layer 402b and the rigid support member 70 can be, but is not limited to, welding or threaded connection. In the antenna sub-array 1001 shown in Figure 8, by connecting at least one sub-reflector layer to the inner wall of the radome 10, and connecting two adjacent sub-reflector layers to the rigid support member 70, at least one sub-reflector layer can be connected to the inner wall of the radome 10 after connecting two adjacent sub-reflector layers to the rigid support member 70. This can effectively improve the assembly efficiency of the reflector 40 and the radome 10.

[0076] Referring again to Figure 8, in this application, the sub-reflector layer 402b furthest from the radiating element 30 can be disposed on the inner sidewall of the radome 10. This sub-reflector layer 402b can be disposed on the radome 10 by, but is not limited to, coating, pasting, or threaded connection. This effectively simplifies the connection method between the reflector 40 and the radome 10.

[0077] It is worth mentioning that when the reflector 40 of the antenna subarray 1001 adopts a configuration of multiple sub-reflector layers, each sub-reflector layer can be a continuous plate structure to ensure the reflector 40 of the antenna subarray 1001 reflects the radio frequency signals radiated by the radiating element 30. In addition, each sub-reflector layer can also be configured as a perforated plate structure. Through the combined design of the perforated patterns of multiple sub-reflector layers, while ensuring the radiation performance of the antenna subarray 1001, radio frequency signals of other specific frequency bands can also pass through the reflector 40 for radiation, thus providing the possibility of stacking multiple antennas with different operating frequency bands.

[0078] Referring to Figure 9, which is another cross-sectional view of the antenna subarray 1001 provided in this application, at least one sub-reflector layer of the reflector 40 of the antenna subarray 1001 includes two opposing bent portions 4021, each bent along the direction from the reflector 40 to the radiating element 30. This effectively improves the performance of the reflector 40 in reflecting the radio frequency signal radiated by the radiating element 30, and also helps to reduce the overall width of the reflector 40, thereby reducing the width of the antenna subarray 1001. It is worth mentioning that in this application, the width direction of the reflector 40 is perpendicular to the axis of the radome 10.

[0079] In this application, the bending angle of the bending portion 4021 of the sub-reflector layer is not limited. For example, the included angle between each bending portion 4021 and the portion of the sub-reflector layer located between the two bending portions 4021 is greater than or equal to 90°. For example, in the antenna sub-array 1001 shown in FIG. 9, the included angle between the two bending portions 4021 of one sub-reflector layer 402a of the reflector 40 and the portion of the sub-reflector layer 402a located between the two bending portions 4021 is 90°, while the included angle between the two bending portions 4021 of the other sub-reflector layer 402b of the reflector 40 and the portion of the sub-reflector layer 402b located between the two bending portions 4021 is greater than 90°. The above is merely an exemplary description of some specific arrangements of the bending portion 4021 of the sub-reflector layer. Based on this, some adaptive modifications can be made to the arrangement of the bending portion 4021 of each sub-reflector layer. For example, the bending angles of the two bending portions 4021 of each sub-reflector layer may be different, and all of these should be understood to fall within the protection scope of this application.

[0080] Referring again to Figure 9, each antenna subarray 1001 may further include two metal baffles 80, which are disposed opposite to each other and connected to the inner wall of the radome 10. The material of the two metal baffles 80 may be, but is not limited to, copper or aluminum. Furthermore, each metal baffle 80 may be connected to the inner wall of the radome 10 by means of adhesion or threaded connection, or the metal baffle 80 may be a metal coating applied to the inner wall of the radome 10.

[0081] It is understood that the two metal baffles 80 of each antenna subarray 1001 are located at the two ends of the reflector 40 facing the adjacent antenna subarray 1001. Therefore, in each antenna subarray 1001, the arrangement direction of the two metal baffles 80 is the same as the arrangement direction of the two bends 4021 in each sub-reflector layer. Furthermore, as shown in Figure 10, the radiating element 30 can be located between the two metal baffles 80. In this way, the two metal baffles 80 can reflect the radio frequency signal radiated by the radiating element 30, which helps to improve the front-to-back ratio performance of the antenna subarray 1001, thereby improving the signal radiation performance of the antenna subarray 1001.

[0082] Referring to Figure 10, which is another cross-sectional view of the antenna subarray 1001 provided in this application, compared with the antenna subarray 1001 shown in Figure 9 above, in Figure 10, the radiating element 30 of the antenna subarray 1001 includes a first radiating part 301 and a second radiating part 302 connected to each other. The first radiating part 301 and the second radiating part 302 are arranged at a predetermined angle, the first radiating part 301 is connected to a reflector 40, and the second radiating part 302 is bent from the first radiating part 301 toward the reflector 40. In this application, the radiating element 30 of the antenna subarray 1001 is designed using the aforementioned two-part bending method, which can effectively reduce the area occupied by the radiating element 30 on the reflector 40. This is beneficial to reducing the size of the reflector 40, thereby reducing the width of the antenna subarray 1001. In this way, the spacing between two adjacent antenna subarrays 1001 can be increased without changing the overall size of the antenna 100, or the size of the antenna 100 can be reduced while ensuring the performance of the antenna 100, thereby helping to reduce the wind resistance of the antenna 100.

[0083] This application does not limit the angle between the first radiating part 301 and the second radiating part 302. For example, in the antenna subarray 1001 shown in FIG10, the angle between the first radiating part 301 and the second radiating part 302 is 90°, that is, the first radiating part 301 and the second radiating part 302 are arranged perpendicularly. In other possible embodiments, the first radiating part 301 and the second radiating part 302 may also be arranged at other angles, which will not be listed here.

[0084] Referring to Figure 10, the antenna subarray 1001 also includes a resistive reactive layer 90, which is connected to the inner wall of the radome 10. The connection method may be, but is not limited to, adhesive bonding or threaded connection, or the resistive reactive layer 90 may be a metal coating applied to the inner wall of the radome 10.

[0085] As shown in Figure 10, the radiating element 30 is located between the resistive reactive layer 90 and the reflector 40. Furthermore, the resistive reactive layer 90 is a metal perforated layer. The radio frequency signal radiated by the radiating element 30 can be radiated through the perforated portion of the resistive reactive layer 90. Thus, by rationally designing the perforated pattern of the resistive reactive layer 90, the bandwidth of the radio frequency signal radiated by the radiating element 30 can be adjusted, thereby improving the signal radiation performance of the antenna subarray 1001.

[0086] In this embodiment, as shown in FIG10, the projection of the band-stop reactive layer 90 on the reflector 40 covers the projection of the radiating element 30 on the reflector 40. This improves the bandwidth adjustment effect of the band-stop reactive layer 90 on the radio frequency signal radiated by the radiating element 30, thereby improving the electrical performance of the antenna subarray 1001.

[0087] It is worth mentioning that Figures 9 and 10 above describe the antenna subarray 1001, which includes a reflector 40 with at least two sub-reflector layers. When the reflector 40 of the antenna subarray 1001 is a single-layer structure, the various structures of the antenna subarray 1001 can also be set with reference to the antenna subarray 1001 shown in Figures 9 and 10. For example, the single-layer reflector 40 can also be provided with a bending portion 4021, the radiating element 30 can also be designed with two bending parts, and the antenna subarray 1001 can also be provided with two metal baffles 80 and a resistive reactance layer 90, etc. The specific settings will not be described in detail here.

[0088] In the above description of the antenna 100 in the embodiments of this application, the structure of the antenna subarray 1001 of the antenna 100 is described using one antenna subarray 1001 as an example. It is understood that the arrangement of each antenna subarray 1001 of the antenna 100 can be the same or different. For example, refer to Figure 11, which is a schematic diagram of another structure of the antenna 100 provided in the embodiments of this application, which is used to show the arrangement of the radiating elements 30 in the antenna 100 on the reflector 40. Each antenna subarray 1001 includes at least two radiating elements 30, which can be arranged in an array on the reflector 40. Specifically, in at least one antenna subarray 1001, at least two radiating elements 30 can be arranged sequentially along the axial direction of the radome 10, that is, at least two radiating elements 30 are arranged into a radiating element array. In another antenna subarray 1001, at least two radiating elements 30 can also be divided into two or more radiating element arrays arranged along the axial direction of the radome 10.

[0089] It is understood that the above embodiments are merely exemplary descriptions of the specific configuration of the antenna 100 provided in this application. Based on this, some adaptive modifications can be made to the antenna subarray 1001, or the various structures in the antenna subarray 1001 described in different embodiments can be reasonably combined. The various possible structures of the antenna subarray 1001 provided in this application will not be described one by one here, but they should all be understood to fall within the protection scope of this application.

[0090] As described above, at least two antenna subarrays 1001 of antenna 100 are connected by mounting structures 1002. In the above embodiments, such as the antenna 100 shown in FIG3 or FIG4, the mounting structure 1002 may be a beam structure, and antenna 100 may include at least two mounting structures 1002, which are spaced apart along the axial direction of the radome 10 of each antenna subarray 1001. In addition, at least one of the radome 10 or reflector 40 of each antenna subarray 1001 is connected to each mounting structure 1002, thereby ensuring a reliable connection of at least two antenna subarrays 1001, which helps to improve the structural reliability of antenna 100.

[0091] In this embodiment, the mounting structure 1002 of the antenna 100 can be configured in other ways besides the above-described configuration. For example, referring to Figure 12a, which is a schematic diagram of another structure of the antenna 100 provided in this embodiment, Figure 12a illustrates one configuration of the mounting structure 1002 of the antenna 100. In the antenna 100 shown in Figure 12a, the mounting structure 1002 is a bent structure, and the antenna 100 includes at least two mounting structures 1002, which are spaced apart. For example, the at least two mounting structures 1002 can be spaced apart along the axial direction of the radome 10 of each antenna subarray 1001. Furthermore, at least one of the radome 10 or reflector 40 of each antenna subarray 1001 is connected to each mounting structure 1002, thereby ensuring a reliable connection between at least two antenna subarrays 1001, which improves the structural reliability of the antenna 100.

[0092] In the antenna 100 shown in Figure 12a, the bending shape of the mounting structure 1002 is arc-shaped. Besides this, the mounting structure 1002 can also be bent into other possible shapes. For example, in the antenna 100 shown in Figure 12b, the bending shape of the mounting structure 1002 is U-shaped. As another example, in the antenna 100 shown in Figure 12c, the bending shape of the mounting structure 1002 is V-shaped. And as another example, in the antenna 100 shown in Figure 12d, the bending shape of the mounting structure 1002 is triangular.

[0093] The mounting structure 1002 of the antenna 100 described in the above embodiments is a fixed form. However, in some possible embodiments of this application, the form of the mounting structure 1002 can be adjusted. For example, in the antenna 100 shown in FIG12e, the mounting structure 1002 includes a first rotating part 10021 and a second rotating part 10022. The first rotating part 10021 and the second rotating part 10022 are hinged by a hinge shaft 10023, which makes the included angle between the first rotating part 10021 and the second rotating part 10022 adjustable. In addition, at least one of the radome 10 or reflector 40 of at least two antenna subarrays 1001 is connected to the first rotating part 10021, and at least one of the radome 10 or reflector 40 of at least two antenna subarrays 1001 is connected to the second rotating part 10022. In the antenna 100 shown in Figure 12e, the overall shape of the antenna 100 can be adjusted by the relative rotation of the first rotating part 10021 and the second rotating part 10022, so that the antenna 100 can meet the requirements of different application scenarios for the shape of the antenna 100, which is conducive to expanding the application range of the antenna 100.

[0094] In the above embodiments of this application, the mounting structure 1002 can be an independent structural component. The mounting structure 1002 can be connected to each antenna subarray 1001 by connecting to the cover 1 or reflector 40 of the radome 10 of each antenna subarray 1001. In some possible embodiments, the mounting structure 1002 can be integrated with some structures of the antenna subarray 1001. For example, in the antenna 100 shown in FIG. 13, the mounting structure 1002 can be integrally formed with the end caps 2 disposed on the same side of at least two antenna subarrays 1001, which simplifies the structure of the antenna 100 and improves the assembly efficiency of the antenna 100.

[0095] It is worth mentioning that in the antenna 100 shown in Figure 13, there are at least two mounting structures 1002. One mounting structure 1002 is integrally formed with the end cap 2 disposed on the same side of at least two antenna subarrays 1001, and the other mounting structure is integrally formed with the end cap 2 disposed on the other side of at least two antenna subarrays 1001, so as to further improve the assembly efficiency of the antenna 100.

[0096] The above embodiments are merely exemplary descriptions of the specific configuration of the mounting structure 1002. Based on this, some adaptive modifications can be made to the configuration of the mounting structure 1002. All possible configurations of the mounting structure 1002 will not be described here, but they should all be understood to fall within the protection scope of this application.

[0097] In addition to the structure described above, the antenna 100 provided in this embodiment may also include a radio frequency (RF) active module 1003. For specific implementation, please refer to Figure 14a, which is a schematic diagram of another structure of the antenna 100 provided in this embodiment. In this antenna 100, the RF active module 1003 is located outside each antenna subarray 1001, and the RF active module 1003 is connected to at least one of the radome 10 or reflector 40 of each antenna subarray 1001. The connection method may include, but is not limited to, snap-fit ​​connection, welding, riveting, or threaded connection. Furthermore, the RF active module 1003 is electrically connected to the radiating element 30 of each antenna subarray 1001. The RF active module 1003 and each radiating element 30 can be electrically connected via a plug-in connection, which improves the convenience of the electrical connection between the RF active module 1003 and each radiating element 30 and saves on the connecting cables between the RF active module 1003 and the radiating element 30, thereby reducing the cost of the antenna 100.

[0098] Referring to Figure 14b, which is a schematic diagram of another structure of the antenna 100 provided in an embodiment of this application, the antenna 100 shown in Figure 14b differs from the antenna 100 shown in Figure 14a. The antenna 100 shown in Figure 14b includes at least two radio frequency active modules 1003, which are located outside each antenna subarray 1001. Each radio frequency active module 1003 is connected to at least one of the radome 10 or reflector 40 of at least one antenna subarray 1001, and each radio frequency active module 1003 is electrically connected to the radiating element 30 of at least one antenna subarray 1001. In a specific implementation, as shown in Figure 14b, the antenna 100 includes two radio frequency active modules 1003 and four antenna subarrays 1001. The two radio frequency active modules 1003 can be connected to form a whole and then connected to at least one of the radomes 10 or reflectors 40 of the four antenna subarrays 1001. In addition, each radio frequency active module 1003 is electrically connected to the radiating elements 30 of the two antenna subarrays 1001. The antenna 100 provided in this application adopts the design shown in Figure 14b, which can effectively improve the flexibility of the arrangement of the radio frequency active modules 1003 and the flexibility of connecting the radio frequency active modules 1003 to the radiating elements 30 of at least two antenna subarrays 1001.

[0099] Furthermore, to further enhance the flexibility of the RF active module 1003 configuration, please refer to Figure 14c, which is another structural schematic diagram of the antenna 100 provided in this embodiment. The antenna 100 shown in Figure 14c includes at least two RF active modules 1003, each corresponding to one of at least two antenna subarrays 1001. Specifically, each RF active module 1003 is located outside the radome 10 of a corresponding antenna subarray 1001, and each RF active module 1003 is electrically connected to the radiating element 30 of a corresponding antenna subarray 1001. This design effectively enhances the flexibility of the overall antenna 100 design, making the antenna 100 applicable to a wider range of scenarios.

[0100] It is understandable that, regardless of which of the above-mentioned settings is adopted for the RF active module 1003 of antenna 100, the RF active module 1003 can be reasonably designed according to specific needs so that each antenna subarray 1001 can work independently and that each antenna subarray 1001 does not affect each other; or each antenna subarray 1001 can be used in combination.

[0101] It is worth mentioning that the above embodiments are merely exemplary descriptions of the specific configuration of the antenna 100 provided in this application. Based on this, some adaptive modifications can be made to the antenna 100, or the various structures of the antennas described in different embodiments can be reasonably combined. For example, in one possible embodiment of this application, the antenna 100 also includes at least two antenna subarrays 1001 and mounting structures 1002. Each antenna subarray 1001 includes an antenna radome 10, a reflector 40, and a radiating element 30. The radiating element 30 is located on one side of the reflector 40 and is connected to the reflector 40. The reflector 40 and the radiating element 30 are housed within the antenna radome 10. The antenna radome 10 includes a cover 1 and two end caps 2. The two end caps 2 are respectively disposed at two ends of the cover 1, and each end cap 2 seals one end of the cover 1. In this embodiment, the radome 10 of the antenna subarray 1001 is not an integral structure; that is, the radome 10 is an assembled structure. In this case, the reflector 40 of the antenna subarray 1001 can also be configured as a perforated plate structure. Other structures of the antenna subarray 1001 can be configured with reference to any of the above embodiments, and will not be elaborated upon here. Furthermore, various possible configurations of the antenna 100 provided in this application will not be described in detail here, but all should be understood to fall within the protection scope of this application.

[0102] When the antenna 100 provided in any of the above embodiments of this application is applied to the base station 1000 shown in FIG. 2, the shape and number of the antenna 100 can be selected according to the specific application scenario. For example, referring to FIG. 15a, FIG. 15a is a schematic diagram of a connection structure between the antenna 100 and the support frame 200 in the base station 1000 shown in FIG. 2. The base station 1000 may include the support frame 200 and three antennas 100. The support frame 200 may be, but is not limited to, a pole or a tower. The mounting structure 1002 of the three antennas 100 are all beam structures, that is, the antennas 100 are designed in a flat plate shape. The three antennas 100 are all connected to the support frame 200, and the three antennas 100 are arranged at equal intervals around the support frame 200. In addition, the radiating element 30 of each antenna 100 is located on the side of the reflector 40 away from the support frame 200. This can achieve three-sector signal coverage of the base station 1000, that is, it can achieve 360° full coverage of the radiated signal of the antenna 100.

[0103] Additionally, referring to Figure 15b, which is a schematic diagram of another connection structure between the antenna 100 and the support frame 200 in the base station shown in Figure 2, the base station 1000 includes only two flat antennas 100 to achieve signal coverage in two sectors. The specific configuration of this base station 1000 is similar to that of the base station 1000 shown in Figure 15a, and will not be described in detail here.

[0104] For example, in the connection structure between the antenna 100 and the support frame 200 shown in Figure 15c, the mounting structure 1002 of the antenna 100 is an arc-shaped bending structure. At least two antenna arrays 1001 of the antenna 100 can be arranged along the arc. In this base station 1000, 360° full coverage of the radiated signal can be achieved by using two antennas 100.

[0105] The above embodiments are merely exemplary descriptions of the specific configuration of the antenna 100 in the base station 1000 provided in this application. Based on this, some adaptive modifications can be made to the number and shape of the antenna 100 according to different application scenarios. These modifications will not be described one by one here, but they should all be understood to fall within the protection scope of this application.

[0106] In this embodiment of the application, referring to Figure 2, the base station 1000 may further include a baseband processing unit 300, which can be connected to the antenna 100 via an active radio frequency module 1003. In some embodiments, the active radio frequency module 1003 may also be referred to as a remote radio unit (RRU), and the baseband processing unit 300 may also be referred to as a baseband unit (BBU).

[0107] As shown in Figure 2, in this embodiment, the radio frequency active module 1003 can be integrated with the antenna 100. The baseband processing unit 300 is located at the far end of the antenna 100. In other embodiments, the radio frequency active module 1003 and the baseband processing unit 300 can also be located simultaneously at the far end of the antenna 100. The radio frequency active module 1003 and the baseband processing unit 300 can be connected by a connecting wire 400.

[0108] Additionally, as shown in Figure 2, a grounding device 500 can be provided between the baseband processing unit 300 and the connecting wire 400. The grounding device 500 generally includes a grounding electrode buried underground. A sealing element can be provided at the connection between the antenna 100 and the connecting wire 400, and a sealing element can also be provided at the connection between the grounding device 500 and the connecting wire 400. Specifically, the sealing element can include at least one of insulating sealing tape and polyvinyl chloride (PVC) insulating tape. Of course, the sealing element can also have other structures and is not limited to the form of tape.

[0109] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
