Description

Technical Field

[0001] This application relates to the field of communication technologies, and particularly to an antenna and a base station. Background Art

[0002] With the development of mobile communication, the usage rate of mobile terminals is getting higher and higher, and the network coverage of mobile cellular networks is the key to mobile communication. The key device in a mobile cellular network is an antenna. Generally, the gain aperture of an antenna is positively correlated with its physical size. That is to say, if you want the antenna to have a higher gain, you need to make the antenna have a larger size.

[0003] However, since the antenna is usually hung on a pole or a tower at a high place, the larger the size of the antenna, the greater the wind resistance it receives, so that the resistance borne by the antenna is greater. This will affect the structural reliability of the antenna and further affect the service life of the antenna. If you want to improve the reliability of the antenna, you need to carry out reinforcement design on the antenna and its installation structure, etc., but this will lead to a significant increase in the cost of antenna installation. Based on this, how to reduce the wind resistance of the antenna while ensuring that the size of the antenna meets the requirements, so that the antenna has a relatively reliable structure, has become a difficult problem that those skilled in the art need to solve urgently. Summary of the Invention

[0004] This application provides an antenna and a base station to reduce the wind resistance of the antenna, thereby improving the structural reliability of the antenna.

[0005] In a first aspect, this application provides an antenna. The antenna includes a mounting structure member and at least two antenna sub-arrays. Each antenna sub-array includes an antenna cover, a reflector, and a radiation unit. The radiation unit is located on one side of the reflector, the radiation unit is connected to the reflector, and the reflector and the radiation unit are accommodated in the antenna cover. Among them, the antenna cover includes a cover body and two end caps. The two end caps are respectively arranged at the two ends of the cover body, and each end cap seals one end of the cover body, so that the antenna cover can protect structures such as the reflector and the radiation plate. In addition, the cover body of the antenna cover is an integrated structure, which can effectively improve the structural reliability of the antenna sub-array. The mounting structure member is located outside the antenna cover of each antenna sub-array. At least one of the antenna cover or the reflector of each antenna sub-array is connected to the mounting structure member, and any two adjacent antenna sub-arrays are spaced apart. There is a ventilation gap between any two adjacent antenna sub-arrays of the antenna provided in this application, which is beneficial to reducing the wind resistance of the antenna, thereby improving the structural reliability of the antenna.

[0006] In a possible implementation manner of the present application, the reflector is a continuous plate-like structure, which can effectively improve the reflection performance of the reflector for the radio frequency signals radiated by the radiation unit. Alternatively, the reflector can be a hollowed-out plate-like structure, and the frequency selectivity of the reflector can be achieved by adjusting the hollowed-out pattern of the reflector, so that the reflector can reflect radio frequency signals of a specific frequency and can transmit radio frequency signals of a specific frequency, enabling the antenna to be stacked with other antennas, thereby realizing the co-planar installation of antennas with different operating frequency bands. It can upgrade and expand the antenna without changing the existing antenna, which is beneficial to reducing the upgrade cost of the antenna and the installation cost of the antenna.

[0007] In a second aspect, the present application also provides an antenna, which includes a mounting structural member and at least two antenna sub-arrays. Each antenna sub-array includes an antenna cover, a reflector, and a radiation unit. The radiation unit is located on one side of the reflector, the radiation unit is connected to the reflector, and the reflector and the radiation unit are accommodated in the antenna cover. Among them, the antenna cover includes a cover body and two end caps. The two end caps are respectively arranged at the two ends of the cover body, and each end cap seals one end of the cover body, so that the antenna cover can protect structures such as the reflector and the radiation plate. In addition, the reflector is connected to the inner side wall of the antenna cover, and the reflector is a hollowed-out plate-like structure. The mounting structural member is located outside the antenna cover of each antenna sub-array, at least one of the antenna cover or the reflector of each antenna sub-array is connected to the mounting structural member, and any two adjacent antenna sub-arrays are arranged at intervals. There is a ventilation gap between any two adjacent antenna sub-arrays of the antenna provided by the present application, which is beneficial to reducing the wind resistance of the antenna, thereby improving the structural reliability of the antenna. In addition, since the reflector is a hollowed-out plate-like structure, the frequency selectivity of the reflector can be achieved by adjusting the hollowed-out pattern of the reflector, so that the reflector can reflect radio frequency signals of a specific frequency and can transmit radio frequency signals of a specific frequency, enabling the antenna to be stacked with other antennas, thereby realizing the co-planar installation of antennas with different operating frequency bands. It can upgrade and expand the antenna without changing the existing antenna, which is beneficial to reducing the upgrade cost of the antenna and the installation cost of the antenna.

[0008] In the antenna provided in the first aspect and the second aspect of the present application, the reflector includes at least two sub-reflector layers, and the at least two sub-reflector layers are stacked along the side away from the radiation unit, and any two adjacent sub-reflector layers are spaced apart. The reflector adopts the above design, and the reflection performance of the reflector for the radio frequency signal radiated by the radiation unit can be improved by the joint design of at least two sub-reflector layers. In addition, by setting the reflector to at least two sub-reflector layers, it is also beneficial to reduce the overall width of the reflector, thereby facilitating the reduction of the width of the antenna subarray, so that the spacing between two adjacent antenna subarrays can be increased without changing the overall size of the antenna, or the size of the antenna can be reduced while ensuring the performance of the antenna, which is beneficial to reducing the wind resistance of the antenna.

[0009] As can be seen from the above description, the reflector is connected to the inner wall of the radome. When the reflector includes at least two sub-reflector layers, each sub-reflector layer can be connected to the inner wall of the radome to improve the connection reliability between the reflector and the radome. Alternatively, at least one sub-reflector layer can be connected to the inner wall of the radome, and two adjacent sub-reflector layers are connected by a rigid support member. In this way, after connecting two adjacent sub-reflector layers to the rigid support member, at least one sub-reflector layer can be connected to the inner wall of the radome, which can effectively improve the assembly efficiency of the reflector and the radome.

[0010] In order to improve the reflection performance of the reflector for the radio frequency signal radiated by the radiation unit, in a possible implementation of the present application, at least one sub-reflector layer of the reflector may include two oppositely disposed bends, each bend being bent in the direction from the reflector to the radiation unit. The above-mentioned design of the sub-reflector layer of the reflector is also conducive to reducing the overall width of the reflector, thereby facilitating reducing the width of the antenna subarray.

[0011] In addition, each antenna subarray further includes two metal baffles, which are arranged opposite to each other and connected to the inner wall of the antenna cover. The radiation unit is located between the two metal baffles, and the arrangement direction of the two bent portions of each reflective plate 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 radiation unit, which is beneficial to improving the front-to-back ratio performance of the antenna subarray, thereby improving the signal radiation performance of the antenna subarray.

[0012] In a possible implementation of the first aspect and the second aspect of the present application, the radiation unit includes a first radiation portion and a second radiation portion connected to each other. The first radiation portion and the second radiation portion are arranged at a set angle. The first radiation portion is connected to the reflector, and the second radiation portion is bent from the first radiation portion towards the reflector. In the present application, the radiation unit of the antenna sub-array is designed in the above-mentioned two-part bending manner, which can effectively reduce the board occupation area of the radiation unit on the reflector, which is beneficial to reducing the size of the reflector, and thus beneficial to reducing the width size of the antenna sub-array.

[0013] In addition, each antenna sub-array further includes a band-stop reactance layer. The band-stop reactance layer is a hollowed metal layer. The radiation unit is located between the band-stop reactance layer and the reflector, and the band-stop reactance layer is connected to the inner side wall of the radome. In this way, the radio frequency signal radiated by the radiation unit can be radiated through the hollowed part of the band-stop reactance layer. By reasonably designing the hollowed pattern of the band-stop reactance layer, the purpose of adjusting the bandwidth of the radio frequency signal radiated by the radiation unit can be achieved, thereby improving the signal radiation performance of the antenna sub-array.

[0014] In the present application, in order to improve the adjustment effect of the band-stop reactance layer on the bandwidth of the radio frequency signal radiated by the radiation unit, the projection of the band-stop reactance layer on the reflector covers the projection of the radiation unit on the reflector. Thereby improving the electrical performance of the antenna sub-array.

[0015] In a possible implementation of the first aspect and the second aspect of the present application, the cross-sectional shape of the radome body can be oval, circular or rounded rectangular, etc. In addition, the radome body can be a tubular structure integrally formed by processes such as extrusion molding. This can ensure the structural reliability of the radome while being beneficial to reducing the width size of the radome, thereby reducing the wind resistance of the antenna.

[0016] In addition, the intervals between any two adjacent antenna sub-arrays are equal. This can reduce the wind resistance of the antenna while meeting the requirements of the array performance of the antenna.

[0017] In the present application, according to different application scenarios of the antenna, there can be various setting forms of the installation structure members. For example, in a possible implementation of the first aspect and the second aspect, the installation structure member is a crossbeam structure. In addition, the antenna includes at least two installation structure members, and the at least two installation structure members are arranged at intervals. At least one of the radome or the reflector of each antenna sub-array is connected to each installation structure member. This can reliably connect at least two antenna sub-arrays through at least two installation structure members, which is beneficial to improving the structural reliability of the antenna.

[0018] In another possible implementation of the first aspect and the second aspect, the mounting structure is a bent structure. At this time, the antenna also includes at least two mounting structures, and the at least two mounting structures are arranged at intervals. At least one of the radomes or reflectors of each antenna sub-array is connected to each mounting structure. In this way, at least two antenna sub-arrays can be reliably connected through at least two mounting structures, which is beneficial to improving the structural reliability of the antenna.

[0019] The bent shape of the mounting structure arranged in a bent structure mentioned above can be U-shaped, V-shaped, arc-shaped, triangular, etc., and it can be specifically designed according to the specific application scenario of the antenna.

[0020] In another possible implementation of the first aspect and the second aspect, the mounting structure includes a first rotating part and a second rotating part. The first rotating part is hinged to the second rotating part. At least one of the radomes or reflectors of at least one of the at least two antenna sub-arrays 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 sub-arrays is connected to the second rotating part. In this way, the overall shape of the antenna can be adjusted by the relative rotation of the first rotating part and the second rotating part, so that the antenna can meet the requirements of different application scenarios for the antenna shape, which is beneficial to expanding the applicable range of the antenna.

[0021] When specifically connecting the mounting structure to the antenna sub-array, in a possible implementation of the first aspect and the second aspect of the present application, the mounting structure can be integrally formed with the end caps arranged on the same side of at least two antenna sub-arrays. This is beneficial to simplifying the structure of the antenna and improving the assembly efficiency of the antenna.

[0022] In addition to the above structure, the antenna provided by the present application also includes a radio frequency active module. The radio frequency active module is located outside the radome of each antenna sub-array. The radio frequency active module is connected to at least one of the radomes or reflectors of each antenna sub-array, and the radio frequency active module is electrically connected to the radiation unit of each antenna sub-array. This is beneficial to improving the convenience of electrically connecting the radio frequency active module to each radiation unit, and can save the connection cables between the radio frequency active module and the radiation unit, thereby being beneficial to reducing the cost of the antenna.

[0023] In a possible implementation of the first aspect and the second aspect of the present application, the antenna includes at least two radio frequency active modules. The at least two radio frequency active modules are located outside the radome of each antenna sub-array. Each radio frequency active module is connected to at least one of the radome or the reflector of at least one antenna sub-array, and each radio frequency active module is electrically connected to the radiation units of at least one antenna sub-array. This can effectively improve the flexibility of the setting of the radio frequency active modules and the flexibility of the connection between the radio frequency active modules and the radiation units of at least two antenna sub-arrays.

[0024] In addition, when the antenna includes at least two radio frequency active modules, at least two radio frequency active modules can be arranged in one-to-one correspondence with at least two antenna sub-arrays. Each radio frequency active module is located outside the radome of a corresponding antenna sub-array, and each radio frequency active module is electrically connected to the radiation units of a corresponding antenna sub-array. With such a design, the flexibility of the overall antenna form design can be effectively improved, so that the antenna is applicable to a wider range of scenarios.

[0025] In a third aspect, the present application further provides a base station, which includes a support frame and the antenna of the first aspect or the second aspect described above. The antenna is connected to the support frame. Since the wind resistance of the antenna of this base station is small, the structural reliability of the antenna is high, which is beneficial to improving the reliability of the structure and signal radiation performance of the base station.

[0049] To make the objectives, technical solutions, and advantages of this application clearer, the following will further describe this application in detail in conjunction with the accompanying drawings. However, the exemplary embodiments can be implemented in various forms and should not be construed as limited to the embodiments described herein. Identical reference numerals in the figures represent the same or similar structures, and thus repeated descriptions thereof will be omitted. The words expressing positions and directions described in the embodiments of this application are illustrative examples based on the accompanying drawings, but can be changed 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 used to illustrate the relative positional relationship and do not represent the actual scale.

[0050] 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 generalizations without departing from the connotation of this application. Therefore, this application is not limited by the specific embodiments disclosed below.

[0051] To facilitate understanding of the antenna and base station provided in this application, the following first introduces its application scenarios. Figure 1 An exemplary schematic diagram of a system architecture applicable to the embodiments of this application is shown, as Figure 1As shown, the 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 can be located in a base station subsystem (BBS), a UMTS terrestrial radio access network (UTRAN), or an evolved universal terrestrial radio access (E-UTRAN) for cell coverage of signals to enable communication between terminal devices and the wireless network. Specifically, the base station 1000 can be a base transceiver station (BTS) in a global system for mobile communication (GSM) or a code division multiple access (CDMA) system, a Node B (NB) in a wideband code division multiple access (WCDMA) system, an evolved Node B (eNB or eNodeB) in a long term evolution (LTE) system, or a radio controller in a cloud radio access network (CRAN) scenario. Or the base station 1000 can also be a relay station, an access point, a vehicle-mounted device, a wearable device, and a g Node (gNodeB or gNB) in a new radio (NR) system, an access network device in a future evolved network, etc. The embodiments of the present application do not limit this.

[0052] The base station 1000 is equipped with an antenna 100 to achieve signal transmission in space. Figure 2 As shown Figure 1 is a schematic diagram of an application scenario of the antenna 100 equipped on the base station 1000 as shown. Figure 2 Shows structures such as a support frame 200 and an antenna 100. Among them, the support frame 200 can be, but is not limited to, a pole or a tower, etc. The antenna 100 is connected to the support frame 200 such as a pole or a tower to facilitate the antenna 100 to receive or transmit signals. The radome 10 has good electromagnetic wave penetration characteristics in terms of electrical performance and can withstand the influence of the external harsh environment in terms of mechanical performance, so as to play a role in protecting the antenna system from the external environment.

[0053] Currently, with the increase in the gain and aperture of antennas, their structural sizes are also getting larger. Additionally, with the improvement of communication rates and the increase in communication bandwidths, antennas usually integrate multiple-input multiple-output (MIMO) technology, that is, multiple columns of radiation units for signal transmission or reception are integrated in one antenna, and the above integrated design of the antenna will also lead to an increase in the antenna size. In addition, the size of the antenna is also related to the operating frequency band. The lower the operating frequency band, the larger the size of the antenna that needs to be matched. From the above introduction of the base station, it can be known that antennas are usually hung at high positions on support frames such as poles or towers, and the larger the size of the antenna, the greater the wind resistance it receives, and at the same time, the more site space the antenna occupies.

[0054] In view of this, the antenna provided in this application is divided into multiple antenna sub-arrays, and the antenna sub-arrays are spaced apart from each other to form a ventilation area, so that while the antenna meets the size design requirements, the wind resistance of the antenna can be effectively reduced, which is beneficial to improving the structural reliability of the antenna and extending the service life of the antenna. To facilitate understanding of the technical solution of this application, the antenna provided in this application will be specifically described below in conjunction with the drawings and specific embodiments.

[0055] Refer to Figure 3 , Figure 3 is a schematic structural diagram of an antenna 100 provided in an embodiment of this application. The antenna 100 includes at least two antenna sub-arrays 1001 and a mounting structure member 1002, and the at least two antenna sub-arrays 1001 are connected by the mounting structure member 1002 to form an antenna array.

[0056] Each antenna sub-array 1001 includes an antenna cover 10. When specifically setting the antenna cover 10, as Figure 3 shown, the antenna cover 10 includes a cover body 1 and two end caps 2. The two end caps 2 are respectively arranged at the two ends of the cover body 1, and each end cap 2 seals one end of the cover body 1, so that the antenna cover 10 forms a closed cavity, so that the antenna cover 10 can play a role in protecting the components accommodated in its cavity from dust, water, etc.

[0057] Refer to Figure 4 , Figure 4 is Figure 3 the A-A cross-sectional view of the antenna 100 shown. In the embodiment of this application, the cover body 1 of the antenna cover 10 can be an integrated structure, that is, the cover body 1 can be prepared by an integral forming processing technology such as extrusion, which is beneficial to improving the structural reliability of the antenna cover 10.

[0058] In some other possible embodiments of the present application, the cover body 1 of the radome 10 can also be an assembled structure, that is, the cover body 1 can be a structure obtained by assembling multiple components, so as to improve the flexibility of the setting of the radome 10.

[0059] In addition, in the present application, the cover body 1 can be a cylindrical structure, and the cross-sectional shape of the cover body 1 is not limited to Figure 5 the rounded rectangle shown, and can also be circular, elliptical or water-drop-like, etc., and will not be listed one by one here.

[0060] Please continue to refer to Figure 4 , each antenna sub-array 1001 further includes a reflector 40 and a radiation unit 30. The reflector 40 and the radiation unit 30 are accommodated in the radome 10. The radiation unit 30 is located on one side of the reflector 40, and the radiation unit 30 is connected to the reflector 40. In addition, the reflector 40 can be connected to the inner side wall of the radome 10, and the connection method can be but not limited to snap connection, bonding or screw connection, etc., so that the reflector 40 can play a reliable supporting role for the radiation unit 30.

[0061] In the embodiments of the present application, the radiation unit 30 can also be referred to as an antenna oscillator, oscillator, etc. The radiation unit 30 is a unit that constitutes the basic structure of the antenna array, and it can effectively radiate or receive antenna signals. The frequencies of different radiation units 30 can be the same or different. The reflector 40 can also be referred to as a bottom plate, an antenna panel or a metal reflecting surface, etc. The reflector 40 can reflect and concentrate the received signals at the receiving point. The radiation unit 30 is placed on one side of the reflector 40, which can not only greatly enhance the signal receiving or transmitting ability, but also block and shield the interference signals from the back of the reflector 40. Among them, in the present application, the back of the reflector 40 refers to the side of the reflector 40 opposite to the side where the radiation unit 30 is set.

[0062] In the embodiments of the present application, as shown in Figure 3 and Figure 4 , the mounting structure member 1002 is located outside the radome 10 of each antenna sub-array 1001. When connecting each antenna sub-array 1001 to the mounting structure member 1002, at least one of the radome 10 or the reflector 40 of each antenna sub-array 1001 can be connected to the mounting structure member 1002. Specifically, in implementation, the cover body 1 of the radome 10 of the antenna sub-array 1001 can be connected to the mounting structure member 1002 through fasteners such as bolts, or the reflector 40 of the antenna sub-array 1001 can be connected to the mounting structure member 1002 through fasteners passing through the radome 10, or the radome 10 and the reflector 40 of the antenna can be both connected to the mounting structure member 1002.

[0063] In addition, please refer to Figure 3 and Figure 4, in the antenna 100 provided by the present application, any two adjacent antenna sub-arrays 1001 are arranged at intervals, so that there is a ventilation gap between any two adjacent antenna sub-arrays 1001, which is beneficial to reducing the wind resistance of the antenna 100 and improving the structural reliability of the antenna 100.

[0064] It is worth mentioning that the present application does not limit the spacing between any two adjacent antenna sub-arrays 1001. Exemplarily, in a possible embodiment, the intervals between any two adjacent antenna sub-arrays 1001 can be made equal to meet the requirements of array performance such as the electrical and physical properties of the antenna 100.

[0065] From the above introduction of the reflector 40 and the radiation unit 30 of the antenna sub-array 1001, it can be understood that in each antenna sub-array 1001, in order to improve the reflection effect of the reflector 40 on the radiation signal of the radiation unit 30, the end of the reflector 40 can be abutted against the inner wall of the radome 10 to make the area of the reflector 40 larger. In addition, the reflector 40 can also be a continuous plate-like structure to improve the reflection performance of the reflector 40. The above-mentioned increase in the area of the reflector 40 and the setting of the reflector 40 as a continuous plate-like structure can effectively ensure the front-to-back ratio performance of the antenna sub-array 1001. In the present application, for the convenience of description, the direction from the reflector 40 to the radiation unit 30 can be defined as the front of the antenna sub-array 1001, and the direction from the radiation unit 30 to the reflector 40 can be defined as the rear of the antenna sub-array 1001. Based on this, it can be understood that the front-to-back ratio performance of the antenna sub-array 1001 refers to the ratio of the energy radiated forward by the antenna sub-array 1001 to the energy radiated backward by the antenna sub-array 1001. The larger the ratio, the smaller the energy radiated backward by the antenna sub-array 1001 and the smaller the impact on other antennas located behind the antenna sub-array 1001.

[0066] In the antenna 100 provided by the present application, the reflector 40 of the antenna sub-array 1001 can be set in other possible forms in addition to the above-mentioned continuous plate-like structure. Exemplarily, referring to Figure 5 , Figure 5 is a schematic structural diagram of a reflector 40 provided by an embodiment of the present application. Figure 5 The shown reflector 40 is a hollow plate-like structure. Among them, the hollow 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 sub-array 1001. For example, it can be a periodic and regular grid-like pattern or an aperiodic and irregular pattern to ensure that the antenna sub-array 1001 has a high front-to-back ratio performance.

[0067] In addition, Figure 5The hollowed-out portion of the hollowed-out pattern 401 of the reflector 40 shown may also be filled with an insulating medium, which may be, for example, plastic, so as to be conducive to improving the front-to-back ratio performance of the antenna sub-array 1001.

[0068] Since a base station generally includes multiple antennas 100 operating at different working frequencies, usually, these multiple antennas 100 all require separate installation surfaces, which results in a limited number of antennas 100 that can be set in the base station. From the above introduction of the reflector 40 of the antenna 100 provided in this application, when the reflector 40 is a hollow plate-like structure, the frequency selectivity of the reflector 40 can be adjusted by adjusting the hollowed-out pattern 401 of the reflector 40, so that the reflector 40 can reflect radio frequency signals of a specific frequency and can transmit radio frequency signals of a specific frequency. Based on this, in the embodiments of this application, when specifically setting the hollowed-out pattern 401 of the reflector 40, the wavelengths of radio frequency signals of other working frequencies may also be considered, so that the antenna 100 provided in this application can be stacked with antennas of other working frequencies. Exemplarily, reference may be made to Figure 6 , Figure 6 which is a schematic structural diagram of the antenna 100 provided in the embodiments of this application stacked with another antenna 100a. In Figure 6 , the other antenna 100a is arranged behind the antenna 100 provided in this application. Since the reflector 40 of the antenna sub-array 1001 of the antenna 100 provided in this application is a hollow plate-like structure, and because any two adjacent antenna sub-arrays 1001 are arranged at intervals, this can make the antenna 100 provided in this application have almost no blockage to the radio frequency signals within a specific frequency band radiated by the other antenna 100a located behind it, so that the other antenna 100a located behind can work normally, thereby realizing the co-planar installation of antennas of different working frequencies. It can upgrade and expand the antenna without changing the existing antenna, which is conducive to reducing the upgrade cost of the antenna and the installation cost of the antenna.

[0069] It is worth mentioning that in the Figure 6 shown structure, the specific setting method of the other antenna 100a is not limited. It can be a traditional antenna or the antenna provided in this application. In addition, Figure 6 only the case of two antennas stacked is shown. In some possible embodiments, the stacked setting of three or more antennas can also be realized by designing the hollowed-out pattern of the reflector.

[0070] In the above embodiments of this application, the reflector 40 is taken as a single-layer structure for introduction. In addition, in this application, the reflector 40 can also be a multi-layer structure. When specifically implementing, reference may be made to Figure 7 , Figure 7Another cross-sectional view of the antenna subarray 1001 provided in the present application can be used to illustrate another structure of the reflector 40 . Figure 7 The reflective plate 40 shown includes at least two sub-reflective plate layers, which are stacked along a side away from the radiation unit 30, and any two adjacent sub-reflective plate layers are spaced apart.

[0071] You can continue to refer to Figure 7 , taking the reflector 40 including the sub-reflector layer 402a and the sub-reflector layer 402b as an example, the sub-reflector layer 402a and the sub-reflector layer 402b are stacked in a direction away from the radiation unit 30, and the adjacent sub-reflector layers 402a and sub-reflector layers 402b are arranged at intervals. The reflector 40 adopts the above design, and the reflection performance of the reflector 40 for the radio frequency signal radiated by the radiation unit 30 can be improved by the joint design of at least two sub-reflector layers. In addition, by setting the reflector 40 to at least two sub-reflector layers, it is also beneficial to reduce the overall width of the reflector 40, thereby facilitating the reduction of the width of the antenna subarray 1001, so that 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 facilitating the reduction of the wind resistance of the antenna 100.

[0072] In addition, if Figure 7 As shown, 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 not limited to clamping or bonding. Figure 8 In the antenna subarray 1001 shown, the sub-reflector layer 402b is connected to the inner wall of the antenna cover 10, and the sub-reflector layer 402b and the adjacent sub-reflector layer 402a are connected through a rigid support member 70, wherein the connection between the sub-reflector layer 402a and the sub-reflector layer 402b and the rigid support member 70 may be, but is not limited to, welding or threaded connection, etc., then Figure 8 In the antenna subarray 1001 shown, at least one sub-reflector layer is connected to the inner wall of the antenna cover 10, and two adjacent sub-reflector layers are connected by a rigid support member 70. After the two adjacent sub-reflector layers are connected to the rigid support member 70, at least one sub-reflector layer can be connected to the inner wall of the antenna cover 10, which can effectively improve the assembly efficiency of the reflector 40 and the antenna cover 10.

[0073] You can continue to refer to Figure 8, in the present application, the sub-reflector layer 402b farthest from the radiation unit 30 can be disposed on the inner sidewall of the radome 10. Among them, the sub-reflector layer 402b can be, but is not limited to, disposed on the radome 10 by means such as coating, pasting or threaded connection. This can effectively simplify the connection method between the reflector 40 and the radome 10.

[0074] It is worth mentioning that when the reflector 40 of the antenna sub-array 1001 adopts a setting method of multiple sub-reflector layers, each sub-reflector layer can be a continuous plate-like structure to ensure the performance of the reflector 40 of the antenna sub-array 1001 for reflecting the radio frequency signals radiated by the radiation unit 30. In addition, each sub-reflector layer can also be set as a hollowed-out plate-like structure, so that through the combined design of the hollowed-out patterns of the multiple sub-reflector layers, while ensuring the radiation performance of the antenna sub-array 1001, radio frequency signals in other specific frequency bands can also pass through the reflector 40 for radiation, thus providing the possibility for the stacked arrangement of antennas with multiple different operating frequency bands.

[0075] Refer to Figure 9 , Figure 9 is another cross-sectional view of the antenna sub-array 1001 provided in the present application. At least one sub-reflector layer of the reflector 40 of the antenna sub-array 1001 includes two oppositely disposed bending portions 4021, and each bending portion 4021 is bent along the direction from the reflector 40 to the radiation unit 30. This can effectively improve the performance of the reflector 40 for reflecting the radio frequency signals radiated by the radiation unit 30, and at the same time is beneficial to reducing the overall width of the reflector 40, thereby being beneficial to reducing the width of the antenna sub-array 1001. It is worth mentioning that in the present application, the width direction of the reflector 40 is perpendicular to the axial direction of the radome 10.

[0076] In the present application, the bending angle of the bending portion 4021 of the sub-reflector layer is not limited. Exemplarily, 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 Figure 9In the illustrated antenna sub-array 1001, the included angles between the two bent portions 4021 of a sub-reflector layer 402a of the reflector 40 and the portion of the sub-reflector layer 402a between the two bent portions 4021 are both 90°, while the included angles between the two bent portions 4021 of another sub-reflector layer 402b of the reflector 40 and the portion of the sub-reflector layer 402b between the two bent portions 4021 are both greater than 90°. The above is only an exemplary description of some specific setting manners of the bent portions 4021 of the sub-reflector layers. On this basis, some adaptive deformations can also be made to the settings of the bent portions 4021 of each sub-reflector layer. For example, the bending angles of the two bent portions 4021 of each sub-reflector layer can be different, and all of them should be understood to fall within the protection scope of this application.

[0077] Continue to refer to Figure 9 , each antenna sub-array 1001 may further include two metal baffles 80. The two metal baffles 80 are arranged oppositely and are connected to the inner side wall of the radome 10. Among them, the material of the two metal baffles 80 can be, but is not limited to, copper or aluminum. In addition, each metal baffle 80 can be connected to the inner side wall of the radome 10 by means of bonding or screw connection, or the metal baffle 80 is a metal coating applied to the inner side wall of the radome 10.

[0078] It can be understood that the above two metal baffles 80 of each antenna sub-array 1001 are respectively located at the two ends of the reflector 40 facing the adjacent antenna sub-array 1001. Then, in each antenna sub-array 1001, the arrangement direction of the two metal baffles 80 is the same as the arrangement direction of the two bent portions 4021 of each sub-reflector layer. In addition, as Figure 10 shown, the radiation unit 30 can be located between the two metal baffles 80. In this way, the two metal baffles 80 can play a role in reflecting the radio frequency signals radiated by the radiation unit 30, which is beneficial to improving the front-to-back ratio performance of the antenna sub-array 1001, and thus can improve the signal radiation performance of the antenna sub-array 1001.

[0079] Refer to Figure 10 , Figure 10 This is another cross-sectional view of the antenna sub-array 1001 provided by this application. Compared with the antenna sub-array 1001 shown in the above Figure 9 , in Figure 10In [the figure], the radiation element 30 of the antenna sub-array 1001 includes a first radiation portion 301 and a second radiation portion 302 which are connected. Among them, the first radiation portion 301 and the second radiation portion 302 are arranged at a set angle, the first radiation portion 301 is connected to the reflector 40, and the second radiation portion 302 is bent from the first radiation portion 301 towards the reflector 40. In this application, the radiation element 30 of the antenna sub-array 1001 is designed in the above-mentioned two-part bending manner, which can effectively reduce the board occupation area of the radiation element 30 on the reflector 40, which is beneficial to reducing the size of the reflector 40, and thus beneficial to reducing the width size of the antenna sub-array 1001. In this way, without changing the overall size of the antenna 100, the distance between two adjacent antenna sub-arrays 1001 can be increased, or the size of the antenna 100 can be reduced while ensuring the performance of the antenna 100, which is beneficial to reducing the wind resistance of the antenna 100.

[0080] This application does not limit the angle between the first radiation portion 301 and the second radiation portion 302. Exemplarily, in Figure 10 the shown antenna sub-array 1001, the angle between the first radiation portion 301 and the second radiation portion 302 is 90°, that is, the first radiation portion 301 and the second radiation portion 302 are perpendicularly arranged. In other possible embodiments, the first radiation portion 301 and the second radiation portion 302 can also be arranged at other angles, and they will not be listed one by one here.

[0081] It can continue to refer to Figure 10 , the antenna sub-array 1001 further includes a band-stop reactance layer 90, and the band-stop reactance layer 90 is connected to the inner side wall of the radome 10. The connection method can be but is not limited to bonding or screw connection, etc. Or the band-stop reactance layer 90 is a metal coating coated on the inner side wall of the radome 10.

[0082] As Figure 10 shown, the radiation element 30 is located between the band-stop reactance layer 90 and the reflector 40. In addition, the band-stop reactance layer 90 is a metal hollow layer, and the radio frequency signal radiated by the radiation element 30 can be radiated through the hollow part of the band-stop reactance layer 90. In this way, by reasonably designing the hollow pattern of the band-stop reactance layer 90, the purpose of adjusting the bandwidth of the radio frequency signal radiated by the radiation element 30 can be achieved, thereby improving the signal radiation performance of the antenna sub-array 1001.

[0083] In the embodiment of this application, as Figure 10 shown, the projection of the band-stop reactance layer 90 on the reflector 40 covers the projection of the radiation element 30 on the reflector 40. In this way, the adjustment effect of the band-stop reactance layer 90 on the bandwidth of the radio frequency signal radiated by the radiation element 30 can be improved, thereby improving the electrical performance of the antenna sub-array 1001.

[0084] It is worth mentioning that in the above Figure 9 and Figure 10 , the antenna sub-array 1001 of the reflector 40 including at least two sub-reflector layers is introduced. When the reflector 40 of the antenna sub-array 1001 is a single-layer structure, the structures of the antenna sub-array 1001 can also refer to the antenna sub-array 1001 shown in the above Figure 9 and Figure 10 . Exemplarily, the single-layer structure reflector 40 can also be provided with a bending portion 4021, the radiation unit 30 can also be designed in a two-part bending manner, and the antenna sub-array 1001 can also be provided with two metal baffles 80 and a band-stop reactance layer 90, etc. The specific setting method is not elaborated here.

[0085] In the introduction of the antenna 100 in the above embodiments of the present application, the structure of the antenna sub-array 1001 of the antenna 100 is described by taking one antenna sub-array 1001 as an example. It can be understood that the setting methods of the respective antenna sub-arrays 1001 of the antenna 100 can be the same or different. Exemplarily, reference can be made to Figure 11 , Figure 11 which is another structural schematic diagram of the antenna 100 provided by the embodiment of the present application, and is used to show the setting method of the radiation unit 30 in the reflector 40 of the antenna 100. Each antenna sub-array 1001 includes at least two radiation units 30, and the at least two radiation units 30 can be arranged in an array on the reflector 40. Specifically, in at least one antenna sub-array 1001, the at least two radiation units 30 can be arranged in sequence along the axis of the radome 10, that is, the at least two radiation units 30 are arranged into a radiation unit array. In another antenna sub-array 1001, the at least two radiation units 30 can also be divided into two or more radiation unit arrays arranged along the axis of the radome 10.

[0086] It can be understood that the above embodiments are only some exemplary descriptions of the specific setting methods of the antenna 100 provided by the present application. On this basis, some adaptive deformations can be made to the antenna sub-array 1001, or the structures in the antenna sub-array 1001 introduced in different embodiments can be reasonably combined. The various possible structures of the antenna sub-array 1001 provided by the present application are not introduced one by one here, but they should all be understood to fall within the protection scope of the present application.

[0087] From the above introduction, it can be known that at least two antenna sub-arrays 1001 of the antenna 100 are connected by the mounting structure member 1002. In the above embodiments, for example Figure 3 or Figure 4In the antenna 100 shown, the mounting structure member 1002 can be a crossbeam structure, and the antenna 100 can include at least two mounting structure members 1002. The at least two mounting structure members 1002 can be arranged at intervals along the axial direction of the radome 10 of each antenna sub-array 1001. In addition, at least one of the radome 10 or the reflector 40 of each antenna sub-array 1001 is connected to each mounting structure member 1002, so that at least two antenna sub-arrays 1001 are reliably connected, which is beneficial to improving the structural reliability of the antenna 100.

[0088] In the embodiment of the present application, in addition to the above-mentioned setting method, the mounting structure member 1002 of the antenna 100 can also adopt other possible setting methods. Exemplarily, referring to Figure 12a , Figure 12a FIG. Figure 12a is another schematic structural diagram of the antenna 100 provided by the embodiment of the present application, Figure 12a which is used to show a setting method of the mounting structure member 1002 of the antenna 100. In the antenna 100 shown, the mounting structure member 1002 is a bent structure. In this antenna 100, there are also at least two mounting structure members 1002, and the at least two mounting structure members 1002 are arranged at intervals. Exemplarily, the at least two mounting structure members 1002 can be arranged at intervals along the axial direction of the radome 10 of each antenna sub-array 1001. In addition, at least one of the radome 10 or the reflector 40 of each antenna sub-array 1001 is connected to each mounting structure member 1002, so that at least two antenna sub-arrays 1001 are reliably connected, which is beneficial to improving the structural reliability of the antenna 100.

[0089] In Figure 12a the antenna 100 shown, the bent shape of the mounting structure member 1002 is arc-shaped. In addition, the mounting structure member 1002 can also be bent into other possible shapes. Exemplarily, in Figure 12b the antenna 100 shown, the bent shape of the mounting structure member 1002 is U-shaped. Another example is that in Figure 12c the antenna 100 shown, the bent shape of the mounting structure member 1002 is V-shaped. Another example is that in Figure 12d the antenna 100 shown, the bent shape of the mounting structure member 1002 is triangular.

[0090] The forms of the mounting structure member 1002 of the antenna 100 introduced in the above embodiments are all fixed forms. In some possible embodiments of the present application, the form of the mounting structure member 1002 can also be adjustable. For example, in Figure 12eIn the antenna 100 shown, the mounting structure member 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 enables the angle between the first rotating part 10021 and the second rotating part 10022 to be adjustable. In addition, at least one of the radomes 10 or reflectors 40 of at least one antenna sub-array 1001 among at least two antenna sub-arrays 1001 is connected to the first rotating part 10021, and at least one of the radomes 10 or reflectors 40 of at least one antenna sub-array 1001 among at least two antenna sub-arrays 1001 is connected to the second rotating part 10022. Then in Figure 12e In the antenna 100 shown, 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 beneficial to expanding the applicable range of the antenna 100.

[0091] In the above embodiments of the present application, the mounting structure member 1002 can be an independent structure member. Then the mounting structure member 1002 can be connected to each antenna sub-array 1001 by connecting to the housing 1 of the radome 10 or the reflector 40 of each antenna sub-array 1001. In some possible embodiments, the mounting structure member 1002 can also be integrally designed with some structures of the antenna sub-array 1001. For example, in Figure 13 In the antenna 100 shown, the mounting structure member 1002 can be integrally formed with the end caps 2 arranged on the same side of at least two antenna sub-arrays 1001, which is beneficial to simplifying the structure of the antenna 100 and improving the assembly efficiency of the antenna 100.

[0092] It is worth mentioning that in Figure 13 In the antenna 100 shown, there are at least two mounting structure members 1002. One mounting structure member 1002 is integrally formed with the end caps 2 arranged on the same side of at least two antenna sub-arrays 1001, and the other mounting structure is integrally formed with the end caps 2 arranged on the other side of at least two antenna sub-arrays 1001 to further improve the assembly efficiency of the antenna 100.

[0093] The above embodiments are only some exemplary descriptions of the specific setting methods of the mounting structure member 1002. On this basis, some adaptive deformations can be made to the setting methods of the mounting structure member 1002. The various possible setting methods of the mounting structure member 1002 will not be introduced one by one here, but they should all be understood to fall within the protection scope of the present application.

[0094] In addition to including the above structure, the antenna 100 provided by the embodiments of the present application may further include a radio frequency active module 1003. During specific implementation, reference can be made toFigure 14a , Figure 14a This is another schematic structural diagram of the antenna 100 provided by the embodiment of the present application. In this antenna 100, the radio frequency active module 1003 is located outside each antenna sub-array 1001, and the radio frequency active module 1003 is connected to at least one of the radomes 10 or reflectors 40 of each antenna sub-array 1001, and the connection method can be but is not limited to snap connection, welding, riveting or screw connection, etc. In addition, the radio frequency active module 1003 is electrically connected to the radiation units 30 of each antenna sub-array 1001. Among them, the radio frequency active module 1003 and each radiation unit 30 can be electrically connected by plugging, which is beneficial to improving the convenience of the electrical connection between the radio frequency active module 1003 and each radiation unit 30, and can save the connection cables between the radio frequency active module 1003 and the radiation unit 30, thereby being beneficial to reducing the cost of the antenna 100.

[0095] Refer to Figure 14b , Figure 14b This is another schematic structural diagram of the antenna 100 provided by the embodiment of the present application. Different from the antenna 100 shown above Figure 14a is that Figure 14b the antenna 100 shown includes at least two radio frequency active modules 1003. The at least two radio frequency active modules 1003 are located outside each antenna sub-array 1001, and each radio frequency active module 1003 is connected to at least one of the radomes 10 or reflectors 40 of at least one antenna sub-array 1001, and each radio frequency active module 1003 is electrically connected to the radiation units 30 of at least one antenna sub-array 1001. Specifically, as Figure 14b shown, the antenna 100 includes two radio frequency active modules 1003 and four antenna sub-arrays 1001. Then 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 sub-arrays 1001. In addition, each radio frequency active module 1003 is electrically connected to the radiation units 30 of two antenna sub-arrays 1001. The antenna 100 provided by the present application adopts the Figure 14b shown design method, which can effectively improve the setting flexibility of the radio frequency active module 1003 and the connection flexibility between the radio frequency active module 1003 and the radiation units 30 of at least two antenna sub-arrays 1001.

[0096] In addition, in order to further improve the setting flexibility of the radio frequency active module 1003, refer to Figure 14c , Figure 14c This is another schematic structural diagram of the antenna 100 provided by the embodiment of the present application. In Figure 14cThe antenna 100 shown includes at least two radio frequency active modules 1003. The at least two radio frequency active modules 1003 are arranged in one-to-one correspondence with at least two antenna sub-arrays 1001. That is, each radio frequency active module 1003 is located outside the radome 10 of a corresponding antenna sub-array 1001, and each radio frequency active module 1003 is electrically connected to the radiation unit 30 of a corresponding antenna sub-array 1001. With such a design, the flexibility of the overall form design of the antenna 100 can be effectively improved, so that the antenna 100 is applicable to a wider range of scenarios.

[0097] It can be understood that no matter which of the above settings the radio frequency active module 1003 of the antenna 100 adopts, the radio frequency active module 1003 can be reasonably designed according to specific needs, so that each antenna sub-array 1001 can work independently and the antenna sub-arrays 1001 do not affect each other; or each antenna sub-array 1001 can be used in cooperation.

[0098] It is worth mentioning that the above embodiments are only some exemplary descriptions of the specific settings of the antenna 100 provided by the present application. On this basis, some adaptive deformations can be made to the antenna 100, or the structures of the antennas introduced in different embodiments can be reasonably combined. Exemplarily, in a possible embodiment of the present application, the antenna 100 also includes at least two antenna sub-arrays 1001 and a mounting structure member 1002. Each antenna sub-array 1001 includes a radome 10, a reflector 40, and a radiation unit 30. The radiation unit 30 is located on one side of the reflector 40, and the radiation unit 30 is connected to the reflector 40. The reflector 40 and the radiation unit 30 are accommodated in the radome 10. The radome 10 includes a housing 1 and two end caps 2. The two end caps 2 are respectively arranged at the two ends of the housing 1, and each end cap 2 seals one end of the housing 1. In this embodiment, the housing 1 of the radome 10 of the antenna sub-array 1001 is not an integrated structure, that is, the housing 1 of the radome 10 is an assembled structure. At this time, the reflector 40 of the antenna sub-array 1001 can also be set as a hollow plate-like structure. The other structures of the antenna sub-array 1001 can be set with reference to any of the above embodiments, and will not be elaborated here. In addition, various possible settings of the antenna 100 provided by the present application will not be introduced one by one here, but they should all be understood to fall within the protection scope of the present application.

[0099] When the antenna 100 provided in any of the above embodiments of the present application is applied to the Figure 2 base station 1000 shown, the form and quantity of the antenna 100 can be selected according to the specific application scenario. Exemplarily, referring to Figure 15a , Figure 15a For Figure 2A schematic diagram of a connection structure between an antenna 100 and a support frame 200 in a base station 1000 is shown. The base station 1000 may include a support frame 200 and three antennas 100, wherein the support frame 200 may be, but is not limited to, a pole or an iron tower, and the mounting structural members 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 radiation unit 30 of each antenna 100 is located on the side of the reflector 40 away from the support frame 200. In this way, three-sector signal coverage of the base station 1000 can be achieved, that is, 360° full coverage of the radiated signal of the antenna 100 can be achieved.

[0100] In addition, refer to Figure 15b , Figure 15b for Figure 2 The base station 1000 includes only two flat-plate-shaped antennas 100 to achieve two-sector signal coverage of the base station 1000. The specific configuration of the base station 1000 is similar to that of the base station 1000. Figure 15a The base station 1000 shown is similar and will not be described in detail here.

[0101] As in Figure 15c In the connection structure between the antenna 100 and the support frame 200 shown, the mounting structure 1002 of the antenna 100 is an arc-shaped bending structure, so at least two antenna arrays 1001 of the antenna 100 can be arranged along the arc. By using two antennas 100 in the base station 1000, 360° full coverage of the radiated signal can be achieved.

[0102] The above embodiments are only some exemplary descriptions of the specific configuration methods of the antenna 100 provided in the base station 1000 according to the embodiments of the present application. On this basis, the number and shape of the antenna 100 can be adaptively modified according to different application scenarios. They will not be introduced one by one here, but they should all be understood to fall within the scope of protection of the present application.

[0103] In the embodiments of the present application, reference may be made to Figure 2 The base station 1000 may further include a baseband processing unit 300, and the baseband processing unit 300 may be connected to the antenna 100 via a radio frequency active module 1003. In some embodiments, the radio frequency active 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).

[0104] like Figure 2As shown, in the embodiment of the present application, the radio frequency active module 1003 can be integrally provided with the antenna 100. The baseband processing unit 300 is located at the far end of the antenna 100. In some other embodiments, the radio frequency active module 1003 and the baseband processing unit 300 can also be located at the far end of the antenna 100 at the same time. The radio frequency active module 1003 and the baseband processing unit 300 can be connected by a connecting wire 400.

[0105] In addition, as Figure 2 shown, a grounding device 500 can also 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 seal can be provided at the connection between the antenna 100 and the connecting wire 400, and a seal can also be provided at the connection between the grounding device 500 and the connecting wire 400. The seal can specifically include at least one of an insulating sealing tape and a polyvinyl chloride (PVC) insulating tape. Of course, the seal can also be other structures and is not limited to the form of a tape.

[0106] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
