Description

Antenna structure and communication equipment

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on November 16, 2023, with application number 202311537968.3 and invention name “An antenna structure and communication device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present invention relates to the field of radio communication technology, and in particular to an antenna structure and communication equipment. Background Art

[0003] The antenna structure is a key part of the wireless communication system, and the performance of the antenna structure directly determines the communication quality of the wireless system.

[0004] In a traditional antenna structure, the antenna structure's connector is installed at the bottom of the antenna structure and transmits RF signals to the antenna array. The antenna structure is hung vertically on a pole, and the remote radio unit (RRU) is connected to the antenna structure's connector via a jumper to achieve RF signal transmission.

[0005] However, in traditional antenna structures, the connector is far away from the antenna array signal connection port, which will cause large transmission loss.

[0006] Summary of the Invention

[0007] An object of the present invention is to provide an antenna structure and a communication device for reducing transmission loss in the antenna structure.

[0008] To achieve the above objectives, the present invention adopts the following technical solutions:

[0009] One aspect of an embodiment of the present application provides an antenna structure, comprising: a radome, an antenna array assembly, a mounting base, and a connector. The radome has a first accommodating cavity, within which the antenna array assembly and the mounting base are both disposed. The antenna array assembly has a radiating surface and a back surface facing away from the radiating surface, and the antenna array assembly has a preset port. The mounting base includes a mounting base body, the mounting base being located on a side of the antenna array assembly where the back surface is located. The mounting base body is provided with a second accommodating cavity, within which the connector is disposed, and the connector is electrically connected to the preset port.

[0010] As can be seen from the above, the antenna array assembly has a radiating surface and a preset port. The connector is electrically connected to the preset port. By transmitting a radio frequency signal to the connector, the radio frequency signal is transmitted through the connector to the preset port, causing the antenna array assembly to emit radio waves through the radiating surface, thereby enabling the antenna structure to transmit radio waves. Alternatively, after the radiating surface of the antenna array assembly receives a radio wave signal, the antenna array assembly transmits the radio frequency signal to the connector through the preset port, and then transmits the signal to the outside of the antenna structure through the connector, thereby enabling the antenna structure to receive radio wave signals. Therefore, when the connector is electrically connected to the preset port, an external device can transmit a radio frequency signal to the preset port of the antenna array assembly through the connector, causing the antenna array assembly to emit radio waves through the radiating surface. At the same time, after the radiating surface of the antenna array assembly receives a radio wave signal, the antenna array assembly transmits the radio frequency signal to the connector through the preset port, and then transmits the radio frequency signal to the external device through the connector, completing the exchange of radio frequency signals between the antenna array assembly and the external device. In addition, the above-mentioned antenna structure may further include a mounting base. The mounting base can be located within the first accommodating cavity, and the mounting body of the mounting base has a second accommodating cavity capable of accommodating the connector, thereby enabling the mounting base to accommodate and protect the connector. The antenna array assembly and mounting base are located within the first accommodating cavity of the radome, thus protecting them and reducing the impact of the external environment on them. In this case, the antenna structure provided herein locates the connector within the second accommodating cavity of the mounting base body. Since the mounting base body is located within the first accommodating cavity, the connector is located within the first accommodating cavity. Furthermore, by fixing the mounting base to the back side of the antenna array assembly, the connector can be located on the back side of the antenna array assembly. In this case, the distance between the connector and the preset port of the antenna array assembly is reduced. Furthermore, by adjusting the mounting base's position so that the mounting base is located near the preset port, the distance between the connector and the preset port is reduced, thereby reducing signal transmission loss between the connector and the preset port. In related art, the connector is located at the bottom of the antenna structure, resulting in a large distance between the connector and the preset port, which results in significant signal transmission loss. In contrast, the antenna structure provided in this embodiment has a smaller distance between the connector and the preset port, thereby reducing transmission loss between the connector and the preset port. This achieves the goal of reducing transmission loss within the antenna structure.

[0011] In some embodiments of the present application, the connector and the preset port can be directly electrically connected. By adjusting the setting position of the mounting base, the mounting base is brought close to the preset port, and the connector and the preset port can be directly electrically connected. In this case, during the transmission of the RF signal, the connector directly transmits the RF signal to the preset port, or the preset port directly transmits the RF signal to the connector, that is, when the RF is transmitted between the preset port and the connector, no path loss is generated. This further reduces the transmission loss within the antenna structure.

[0012] In other embodiments of the present application, the antenna structure may further include a first cable, disposed within the first accommodating cavity, with a first end of the first cable electrically connected to the preset port and a second end of the first cable electrically connected to the connector. If the mounting base is limited by the mounting space on the side of the antenna array where the back is located and cannot be installed near the preset port, preventing direct electrical connection between the connector and the preset port, the connector and the preset port can be electrically connected via the first cable. In this case, RF signals can be transmitted between the connector and the preset port via the first cable. Furthermore, the connector and the first cable electrically connecting the connector to the preset port of the antenna array assembly are both located on the back of the antenna array assembly. This allows the first cable and connector to be located on the same side of the antenna array assembly, thereby reducing the length of the first cable. In related art, the connector is located at the bottom of the antenna structure, meaning that the length of the feeder cable electrically connecting the connector to the preset port needs to be greater than the distance from the bottom of the radome to the preset port. This results in a longer feeder cable and greater transmission loss. In the antenna structure provided in the embodiments of the present application, the mounting base can be disposed near the preset port, thereby reducing the distance between the connector and the preset port and the required length of the first cable, thereby reducing transmission loss within the antenna structure. In some embodiments of the present application, a mounting hole may be provided on the mounting seat body. The end of the connector close to the antenna array assembly passes through the mounting hole and is electrically connected to the preset port. By providing a mounting hole close to the preset port on the mounting seat body, it is ensured that the connector can be directly electrically connected to the preset port. Alternatively, when the connector needs to be electrically connected to the preset port through a first cable, the first cable can be electrically connected to the connector on the outside of the mounting seat body. At this time, the first cable can be electrically connected to the connector without bypassing the mounting seat body or extending into the second accommodating cavity, thereby further reducing the length of the first cable and further reducing the transmission loss of the first cable.

[0013] In some embodiments of the present application, the second accommodating cavity is a groove, and the opening of the groove faces away from the back surface; the groove has a first groove wall on the side close to the preset port, and a mounting hole is provided on the first groove wall. In summary, a mounting hole is provided on the first groove wall on the side of the groove close to the preset port, and one end of the connector is electrically connected to the preset port or the first cable after passing through the mounting hole. At this time, one end of the connector extends beyond the side wall of the groove and is located on the side of the mounting seat body close to the preset port. When the distance between the mounting seat body and the preset port is constant, the distance between the end of the connector passing through the mounting hole and the preset port is shorter, and the transmission loss between the preset port and the connector is smaller. The preset port further reduces the transmission loss inside the antenna structure.

[0014] In some embodiments of the present application, the plane where the first groove wall is located may intersect with the back surface, and the angle between the plane where the first groove wall is located and the back surface is a first angle α, and the opening of the first angle α faces the preset port; wherein 0<α≤90°. For example, the first angle α is 5°, 25°, 45°, 65°, 80°, 90°, etc. When the connector needs to be electrically connected to the preset port through the first cable, a mounting hole is provided on the first groove wall, and one end of the connector passes through the mounting hole and is electrically connected to the first cable. The opening of the first angle α between the first groove wall and the back surface faces the preset port, that is, the preset port, one end of the connector passing through the mounting hole, and the first cable used to connect the preset port and the connector are all located on the same side of the first groove wall. In this case, the required length of the first cable is shorter. In addition, when α=90°, the first groove wall is perpendicular to the back surface, and the axis of the mounting hole opened on the first groove wall is parallel to the back surface. After one end of the connector passes through the mounting hole, its extension direction is parallel to the rear surface. Because the connector end passing through the mounting hole, the preset port, and the first cable are all located on the same side of the first slot wall, when the first cable is connected to the connector and the preset port, the second end of the first cable extends parallel to the rear surface. The first cable can be connected to the connector without bending. When 0 < α < 90°, the end of the first slot wall away from the rear surface is inclined toward the preset port. After one end of the connector passes through the mounting hole, the end passing through the mounting hole extends toward the rear surface, while the second end of the first cable for electrical connection to the connector extends away from the rear surface. In this case, the first cable only needs to be bent once, away from the rear surface, and the angle of the bend is greater than 90°, resulting in a smaller bend and easier bending. When the first angle α is greater than 90°, the second end of the first cable must extend toward the rear surface. When connecting the preset port and the connector, the first cable must first bend in a direction away from the rear surface and then bend toward the rear surface. This means the first cable must be bent at least twice. Furthermore, the angle at which the first cable is bent at the connection with the connector is small, resulting in a large degree of bending, which is inconvenient for installation and requires a long length of the first cable. Therefore, the first cable in the antenna structure provided in the embodiment of the present application does not need to be bent or only needs to be bent once when connected to the connector. Furthermore, the angle at the bend is large, facilitating installation of the first cable and the connector, and reducing the length of the first cable. This improves the installation convenience of the antenna structure while reducing transmission loss in the first cable.

[0015] In some embodiments of the present application, the groove may have a second groove wall, with a second angle β formed between the first groove wall and the second groove wall; wherein 45°≤β<180°; illustratively, the second angle β is 45°, 60°, 90°, 120°, 135°, 150°, 175°, etc. In this case, the opening at the second angle between the first groove wall and the second groove wall is larger, providing more maneuverability for workers when inserting an external cable into the groove and connecting it to the connector, facilitating installation of the external cable and connector. However, when the grooves have the same groove depth, if the second angle β between the first groove wall and the second groove wall is less than 45°, the groove opening is smaller, providing less maneuverability for workers when inserting an external cable into the groove and connecting it to the connector, making connection more difficult. Therefore, the antenna structure provided in embodiments of the present application facilitates installation of the external cable and connector, thereby improving the ease of installation and maintenance of the antenna structure and the external cable.

[0016] In some embodiments of the present application, mounting holes are provided in the second slot wall. When multiple groups of RF signals are exchanged between the preset port and an external device, the antenna structure requires a large number of connectors. Different connectors can be passed through the mounting holes provided in the first slot wall or the second slot wall and electrically connected to the preset port, ensuring that the groove can accommodate the required number of connectors.

[0017] In some embodiments of the present application, the mounting base may further include a reinforcing rib disposed between the first slot wall and the second slot wall, the reinforcing rib being connected to at least one of the first slot wall and the second slot wall. The reinforcing rib can increase the rigidity of the connection between the first slot wall and the second slot wall, thereby improving the structural stability of the mounting base.

[0018] In some embodiments of the present application, the second accommodating cavity can be a groove, with the opening of the groove facing away from the rear surface; a mounting hole is formed at the bottom of the groove, and the bottom of the groove is parallel to the rear surface. In this case, the axis of the mounting hole formed at the bottom of the groove is perpendicular to the rear surface. After one end of the connector passes through the mounting hole, the connector extends perpendicular to the rear surface, and the connector is disposed at the bottom of the groove. If the installation space of the mounting base is small, the groove can accommodate the connector if it has a small depth.

[0019] In some embodiments of the present application, the groove may have multiple groove walls, and the groove walls and the bottom have a third angle γ; wherein 80°≤γ<100°; for example, the third angle γ is 80°, 85°, 90°, 95°, and 100°. At this time, the projected areas of the bottom of the groove and the open end of the groove on the back are relatively close or the same. In the direction parallel to the back, when the assembly space of the mounting base is limited, that is, when the projected area of ​​the mounting base body on the back is the same, when 80°≤γ<100°, the space of the groove is larger and can accommodate more connectors, ensuring that the number of connectors that can be accommodated in the groove meets the requirements. When the third angle γ is less than 80° or greater than 100°, the inclination of the groove wall is greater, and when the projected area of ​​the mounting base body on the back is the same, the space of the groove is smaller. Therefore, the groove of the antenna structure provided in the embodiment of the present application can accommodate more connectors to meet the transmission requirements of the RF signal of the antenna array assembly.

[0020] In some embodiments of the present application, the groove may have multiple groove walls intersecting with the bottom, and at least one groove wall may have a mounting hole. If the antenna structure requires a large number of connectors, the connectors can be mounted separately to the bottom or the groove walls to ensure that the groove can accommodate the required number of connectors.

[0021] In some embodiments of the present application, the connector and the mounting base body can be sealed together at the mounting hole. For example, the mounting base body is provided with a sealing ring at the mounting hole, and the sealing ring is placed on the end of the connector near the antenna array assembly. Alternatively, a sealant is applied to the inner wall of the mounting hole, and the end of the connector near the antenna array assembly is sealed to the inner wall of the mounting hole via the sealant. In this case, the second receiving chamber of the mounting base body is relatively sealed with the first receiving chamber of the radome at the mounting hole, preventing moist air in the second receiving chamber from entering the first receiving chamber, causing corrosion of components in the first receiving chamber and thus affecting the performance of the antenna structure. This improves the operational stability and service life of the antenna structure.

[0022] In some embodiments of the present application, the mounting base may further include a mounting bracket. The mounting bracket may be disposed on a side of the mounting base body facing the back surface, with one end of the mounting bracket connected to the mounting base body and the other end of the mounting bracket connected to the antenna array assembly. The mounting bracket is respectively connected to the mounting base body and the antenna array assembly, and the mounting base body and the antenna array assembly are relatively fixed by the mounting bracket. In this case, the mounting bracket can provide support for the mounting base body and, at the same time, increase the distance between the mounting base body and the back surface of the antenna array assembly through the mounting bracket, ensuring that the connector in the first accommodating cavity is close to the inner wall of the radome facing away from the back surface, facilitating the connection and installation of the connector with the external cable.

[0023] In some embodiments of the present application, the mounting bracket may have an assembly space, and the mounting base body may be disposed within the assembly space. The assembly space may be the space enclosed by the mounting bracket's frame. Once the mounting base body is disposed within the assembly space, the mounting bracket can protect the mounting base body, preventing deformation of the mounting base body due to stress, which could affect the stability of the connection between the connector and the mounting base body.

[0024] In some embodiments of the present application, the second accommodating cavity may be a groove, with the opening of the groove facing away from the back surface. The mounting base may further include a flange, which is fixedly disposed at the open end of the groove and connected to the radome. In this case, the mounting base body may be fixedly connected to the radome via the flange. Moreover, the flange is disposed around the open end of the groove and does not obstruct the opening of the groove, thereby ensuring connection space between the connector in the groove and the external cable. Furthermore, the flange can increase the area of ​​the connection between the mounting base and the radome, facilitating the drilling of holes or the application of glue on the flange to ensure relative fixation between the mounting base and the radome.

[0025] In some embodiments of the present application, the radome may be provided with a first connection hole that communicates with the second accommodating cavity. In this case, an external cable can be passed through the first connection hole and electrically connected to a connector within the second accommodating cavity, thereby facilitating installation of the external cable. Furthermore, when connecting the external cable, there is no need to pull the connector out of the radome, making installation simple and convenient.

[0026] In some embodiments of the present application, the antenna structure may further include a waterproof component, which is arranged on the outside of the panel of the antenna cover having a first connection hole. The waterproof component includes a waterproof component body and a boss, and a second connection hole is provided on the waterproof component body, and the second connection hole is connected to the first connection hole. The boss is provided on the side of the waterproof component body close to the mounting seat, and one end of the boss extends into the first connection hole and abuts against the mounting seat. After the boss of the waterproof component abuts against the mounting seat, it can shield the connection between the mounting seat and the antenna cover, thereby improving the waterproof performance of the connection between the mounting seat and the antenna cover. In addition, the waterproof component has a second connection hole that is connected to the first connection hole, and the external cable can pass through the second connection hole, the first connection hole and the connector in the second accommodating cavity in sequence to ensure the convenience of installation of the external cable.

[0027] In some embodiments of the present application, the antenna structure may further include a first sealing member disposed between the waterproof member and the radome. For example, the first sealing member is a waterproof rubber strip or a sealing ring. The first sealing member ensures a tight seal between the waterproof member and the radome, preventing moisture or rainwater from entering the connection between the radome and the mounting base through the connection between the waterproof member and the radome, ultimately entering the first accommodating cavity. This protects components within the first accommodating cavity from corrosion by moisture or rainwater, which could affect the performance of the antenna structure. This improves the operational stability and service life of the antenna structure.

[0028] In some embodiments of the present application, the antenna structure may further include a second sealing member disposed between the mounting base and the radome. For example, the second sealing member may be a waterproof rubber strip or a sealing ring. This second sealing member ensures a tight seal between the mounting base and the radome, preventing moisture or rain from entering the first accommodating cavity through the connection between the radome and the mounting base. This protects components within the first accommodating cavity from corrosion by moisture or rain, which could affect the performance of the antenna structure. This improves the operational stability and service life of the antenna structure.

[0029] In some embodiments of the present application, the antenna structure may further include a first connector. The mounting base may be provided with a first fixing hole, and the radome may be provided with a second fixing hole. The first connector passes through the second fixing hole and the first fixing hole in sequence and is fixedly connected to the mounting base. For example, the first connector is a bolt or a screw, and the first fixing hole is a threaded hole. After passing through the second fixing hole, the first connector is threadedly connected to the first fixing hole, thereby ensuring that the mounting base and the radome are fixedly connected. Alternatively, the first connector is a pin, and the first fixing hole is a pin hole. After passing through the second fixing hole, the first connector is interference-fitted with the first fixing hole, thereby ensuring that the mounting base and the radome are fixedly connected. After the first connector is fixedly connected to the mounting base, a force can be applied to the mounting base and the radome to move closer to each other, thereby ensuring that the mounting base and the radome are relatively fixed, while also making the mounting base and the radome fit more tightly, thereby improving the sealing of the connection between the mounting base and the radome.

[0030] In some embodiments of the present application, an antenna array assembly may include a reflector and a plurality of radiating units arranged in an array, wherein the radiating surface of the antenna array assembly is the end surface of the radiating unit facing away from the reflector, and the reflector has a reflecting surface close to the radiating surface. The radiating unit can transmit or receive radio waves, and the reflecting surface of the reflector can reflect the radio waves so that the radio waves are concentrated at the receiving point of the radiating unit, thereby enhancing the receiving capability of the radiating unit. In addition, the back surface of the antenna array assembly is the end surface of the reflector facing away from the radiating surface, and a preset port is provided on the end surface of the reflector facing away from the radiating surface. The antenna array assembly may further include a feeding network, the feeding network being electrically connected to the radiating unit, and the feeding network being electrically connected to the preset port. After receiving the radio wave, the radiating unit transmits a radio frequency signal to the preset port through the feeding network, and then transmits it to the outside of the antenna array assembly through the preset port, or after the outside transmits the radio frequency signal to the preset port, it is transmitted to the radiating unit through the feeding network. After receiving the radio frequency signal, the radiating unit emits radio waves outward. The preset port is electrically connected to the connector, and then electrically connected to the external device through the connector, ultimately achieving the purpose of the radiation unit receiving or transmitting radio waves and transmitting signals with the external device.

[0031] In some embodiments of the present application, the distance between the end of the connector facing away from the antenna array assembly and the first inner wall of the radome is a first distance h1, and the distance between the end face of the mounting base facing away from the rear surface and the first inner wall is a second distance h2, and h1 ≥ h2. The first inner wall is the inner wall of the radome on the side of the mounting base facing away from the rear surface. In this case, the end of the connector facing away from the antenna array assembly does not protrude beyond the end face of the mounting base. When the radome is placed over the assembled antenna array, reflector, mounting base, and connector, friction between the connector and the inner wall of the radome is avoided, thereby preventing the radome from repeatedly rubbing against the connector during assembly, thereby preventing passive intermodulation (PIM) problems caused by the radome. Furthermore, the mounting base protects the connector, further providing protection for the connector.

[0032] In some embodiments of the present application, there are at least two preset ports, there are at least two first cables, the center point of the two farthest preset ports is a first position, and the distance between the mounting base and the first position is a first length, wherein the first length is less than the distance between the mounting base and any of the preset ports. When there are at least two preset ports, the distance between the mounting base and the first position is less than the distance between the mounting base and any of the preset ports, i.e., the mounting base is located between the at least two preset ports. In this case, the sum of the distances between the mounting base and the preset ports is smaller, thereby reducing the total length of the required first cables and achieving the purpose of reducing transmission loss.

[0033] In some embodiments of the present application, the preset port includes at least two connectors, the antenna structure includes at least two first cables and at least two connectors, the first ends of the first cables are electrically connected to the connectors of the preset port in a one-to-one correspondence, and the second ends of the first cables are electrically connected to the connectors in a one-to-one correspondence. When the preset port needs to transmit multiple sets of radio frequency signals to the outside, it can be electrically connected to the corresponding first cables through different connectors, the first cables are electrically connected to the corresponding connectors, and the connectors are used to electrically connect to the outside, so that the preset port has multiple signal transmission paths with the outside, thereby transmitting multiple sets of radio frequency signals.

[0034] Another aspect of the present application provides a communications device that may include any of the aforementioned antenna structures. The communications device may also include a communications support, a second cable, and a remote radio frequency unit. The antenna structure and the remote radio frequency unit are respectively disposed on the communications support. One end of the second cable is electrically connected to an end of the antenna structure's connector facing away from the antenna array assembly, and the other end of the second cable is electrically connected to the remote radio frequency unit. The aforementioned communications device has the same technical effects as the antenna structure provided in the aforementioned embodiments and will not be further described here.

[0035] In some embodiments of the present application, the remote radio unit is disposed on the outer wall of the antenna structure's radome. In this case, the remote radio unit is located closer to the connector. When the connector and the remote radio unit are electrically connected via a second cable, the required length of the second cable is reduced, thereby reducing transmission loss in the second cable. This reduces RF signal transmission loss between the antenna structure and the remote radio unit.

[0036] In some embodiments of the present application, the antenna structure may further include a support frame and a second connector disposed within the first accommodating cavity. Furthermore, the radome is provided with a third fixing hole. One end of the second connector passes through the third fixing hole and connects to the support frame, while the other end of the second connector connects to the remote radio unit. In this case, the remote radio unit is connected to the support frame via the second connector and relatively fixed. The support frame provides support and fixation for the remote radio unit, allowing it to be stably mounted on the side wall of the radome.

[0037] In some embodiments of the present application, the antenna structure may further include a support base, which is disposed on the outer wall of the radome on the side of the mounting base facing away from the rear surface and is connected to the radio remote unit. Furthermore, the support base is provided with a fourth fixing hole, through which one end of the second connector passes, in sequence, through the fourth fixing hole and the third fixing hole and is connected to the support frame. After the second connector passes through the fourth fixing hole and the third fixing hole and is connected to the support frame, the support base, radome, and support frame are relatively fixed, and the radio remote unit is then connected to the support base, thereby securing the radio remote unit to the outer wall of the radome.

DETAILED DESCRIPTION

[0069] A communication system architecture 01 provided in an embodiment of the present application, as shown in Figure 1, may include a communication device 02 and a terminal device 03, and the communication device 02 may perform wireless communication with the terminal device 03. For example, the communication device 02 may include a base station. The base station is used to provide cell coverage for wireless signals to achieve connection between the terminal device and the radio frequency end of the wireless network. Based on this, for example, the base station may be a base station (base transceiver station, BTS) in a global system of mobile communication (GSM) system or a code division multiple access (CDMA) system. Or, for another example, the base station may be a base station (Node B, NB) in a wideband code division multiple access (WCDMA) system. Or, for another example, the base station may be an evolutionary Node B (eNB) in a long term evolution (LTE) system, or a wireless controller in a cloud radio access network (CRAN) scenario. Alternatively, the above-mentioned base station can be a relay station, an access point, a vehicle-mounted device, a wearable device, and a base station in a 5G network, or it can also be a base station in a future evolved public land mobile network (PLMN) network, for example, a new wireless base station, and the embodiments of the present application are not limited to this.

[0070] In addition, the terminal device 03 may be a mobile phone, a tablet computer (pad), a laptop computer, a smart home, a smart wearable device (e.g., a smart watch, a smart bracelet, smart glasses, a smart helmet), a virtual reality (VR) device, an augmented reality (AR) device, etc. The terminal device 03 may also be a handheld terminal device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a device in a 5G network, or a terminal device in a future evolved PLMN, etc., and the embodiments of the present application are not limited thereto.

[0071] In the case where the communication device 02 is a base station, in some embodiments of the present application, the communication device 02 may include the antenna structure 10, the communication support 20, the second cable 30, and the remote radio frequency unit 40 shown in Figure 2. The antenna structure 10 and the remote radio frequency unit 40 are respectively disposed on the communication support 20. One end of the second cable 30 can be electrically connected to the antenna structure 10, and the other end of the second cable 30 can be electrically connected to the remote radio frequency unit 40. The antenna structure 10 transmits signals to the remote radio frequency unit 40 via the second cable 30. The remote radio frequency unit 40 is used to transmit radio frequency signals.

[0072] For example, the communication bracket 20 may include a pole 21, which can secure and support the antenna structure 10. Furthermore, the communication bracket 20 may also include an adjustment arm 22 and a clamp 23. The adjustment arm 22 is located between the antenna structure 10 and the pole 21. One end of the clamp 23 is connected to the adjustment arm 22, and the other end of the clamp 23 is connected to the pole 21. The antenna structure 10 can be connected to the pole 21 via the adjustment arm 22 and the clamp 23 in sequence. The adjustment arm 22 can adjust the pitch angle of the antenna structure 10 relative to the pole 21.

[0073] As shown in FIG2 , the above embodiment takes the radio remote unit 40 as an example, in which the radio remote unit 40 is disposed on the pole 21 . In other embodiments of the present application, the radio remote unit 40 may also be disposed on a tower, a rooftop, or other location close to the antenna structure 10 .

[0074] Based on this, in some embodiments of the present application, the antenna structure 10 may include a radome 11, a connector 14, and a mounting base 13, as shown in FIG3A . The mounting base 13 includes a mounting base body 131. The mounting base body 131 has a second accommodating cavity 1311 for accommodating the connector 14. After the connector 14 is placed in the second accommodating cavity 1311, the mounting base body 131 can accommodate and protect the connector 14. Furthermore, the connector 14 shown in FIG3A may be an MQ quick-connect connector or a DIN connector.

[0075] The antenna structure 10 may include an antenna array assembly 12 as shown in FIG3B or FIG4 . The antenna cover 11 has a first accommodating cavity 111 for accommodating the antenna array assembly 12 and the mounting base 13 . The antenna cover 11 can resist the influence of the external environment of the antenna structure 10 and protect the antenna array assembly 12 and the mounting base 13 disposed in the first accommodating cavity 111 .

[0076] As shown in FIG3C , the antenna array assembly 12 has a radiating surface 121, a back surface 122 facing away from the radiating surface 121, and a preset port 123 located on the back surface 122. The antenna array assembly 12 can receive radio waves through the radiating surface 121 and transmit radio frequency signals to the connector 14 through the preset port 123. Alternatively, the antenna array assembly 12 can receive radio frequency signals from the connector 14 through the preset port 123 and then transmit radio waves through the radiating surface 121. To facilitate the antenna array assembly 12 transmitting radio wave signals received from different areas of the radiating surface 121 outward through the preset port 123, the preset port 123 can be located near the center of the back surface 122, depending on the distribution of components within the antenna structure 10. In this case, the preset port 123 is electrically connected to the connector 14. By transmitting the radio frequency signal to the connector 14, the radio frequency signal is transmitted through the connector 14 to the preset port 123 of the antenna array assembly 12, so that the antenna array assembly 12 transmits radio waves through the radiating surface 121, thereby enabling the antenna structure 10 to transmit radio waves. When the antenna array assembly 12 receives radio waves through the radiating surface 121, the antenna array assembly 12 transmits the radio frequency signal to the connector 14 through the preset port 123, and transmits it to the radio frequency remote unit 40 (as shown in Figure 2) through the connector 14, thereby enabling the antenna structure 10 to receive radio wave signals. At this time, by setting the mounting base 13 close to the preset port 123, the distance between the connector 14 and the preset port 123 is reduced, thereby reducing the signal transmission loss between the connector 14 and the preset port 123. The purpose of reducing transmission loss within the antenna structure is achieved.

[0077] In some embodiments of the present application, as shown in FIG4 , one end of the connector 14 close to the antenna array assembly 12 can be directly electrically connected to the preset port 123 (as shown in FIG3C ). In the related art, the connector provided at the bottom of the antenna structure needs to be electrically connected to the preset port on the back through a feeder, and the length of the feeder used to electrically connect the connector to the preset port needs to be greater than the distance between the bottom of the antenna cover and the preset port, so the feeder length is long and the transmission loss is large. In the embodiment of the present application, by adjusting the setting position of the mounting base 13 so that the mounting base 13 is close to the preset port 123, the connector 14 can be directly electrically connected to the preset port 123 without the need for cables or other transmission media. When radio frequency is transmitted between the preset port 123 and the connector 14, no path loss is generated. This achieves the purpose of further reducing the transmission loss within the antenna structure 10.

[0078] In other embodiments of the present application, the antenna structure 10 may include a first cable 15 disposed in a first accommodating cavity 111 as shown in FIG3B . The first end a1 of the first cable 15 is electrically connected to the preset port 123, and the second end a2 of the first cable 15 is electrically connected to the connector 14 (as shown in FIG3A ). At this time, as shown in FIG3C , the preset port 123, the first cable 15 and the connector 14 are electrically connected in sequence, and the radio frequency signal can be transmitted between the preset port 123, the first cable 15 and the connector 14. By setting the mounting base 13 close to the preset port 123, the distance between the connector 14 and the preset port 123 is reduced, and the required length of the first cable 15 is reduced, thereby achieving the purpose of reducing the transmission loss in the antenna structure 10. On this basis, as shown in FIG3C , the antenna array assembly 12 may include a reflector 125 and a plurality of radiating units 124 arranged in an array. Each radiating unit 124 includes a radiator, and the radiator can radiate or receive radio waves. The radiation surface 121 of the antenna array assembly 12 is the radiation surface of the radiator of the radiation unit 124, and the back surface of the antenna array assembly 12 is the end surface of the reflector 125 away from the radiation surface 121. Of course, the components of the antenna array assembly 12 away from the radiation surface 121 can also protrude from the back surface 122. In addition, the reflector 125 also has a reflecting surface, which is the end surface facing the radiation surface 121. When the radiation unit 124 receives radio waves, the reflecting surface of the reflector 125 can reflect the radio waves, so that the radio waves are concentrated on the receiving point of the radiation unit 124, thereby enhancing the receiving ability of the radiation unit 124. At the same time, the reflector 125 can also block and shield other radio waves from the back, preventing other radio waves from the back from interfering with the receiving effect of the radiation unit 124.

[0079] In addition, as shown in FIG3D , the antenna array assembly 12 may further include a feed network 126, which is electrically connected to the radiators of the radiating elements 124. At the same time, the feed network 126 is electrically connected to the preset port 123. That is, the radiator of each radiating element 124 is electrically connected to the preset port 123 via the feed network 126. When any radiator of the radiating element 124 receives radio waves, it can transmit the RF signal to the preset port 123 via the feed network 126. The preset port 123 then transmits the signal to the radio remote unit 40 via the first cable 15 and the connector 14. When radio waves need to be transmitted through the radiators of the radiating element 124, the radio remote unit 40 transmits the RF signal to the connector 14. After the signal is transmitted to the preset port 123 via the connector 14 and the first cable 15, the RF signal is distributed and transmitted to the radiators of the multiple radiating elements 124 via the feed network 126, and the radiators then emit radio waves. Ultimately, the antenna structure receives or transmits radio waves and transmits radio frequency signals with the radio remote unit 40 .

[0080] When the antenna array assembly 12 needs to transmit with the radio frequency remote unit 40 (as shown in Figure 2) through a set of signal transmission paths, the preset port 123 may include a connector 1231, and the antenna structure 10 may include a connector 14, and the connector 14 is directly electrically connected to the connector 1231, or the connector 14 is electrically connected to the connector 1231 through a first cable 15.

[0081] Alternatively, when the antenna array assembly 12 needs to transmit with the radio remote unit 40 (as shown in FIG2 ) through N groups of signal transmission paths, the preset port 123 may include N connectors 1231, and the antenna structure 10 may include N connectors 14, each connector 14 being electrically connected to a connector 1231, or each connector 14 being electrically connected to a connector 1231 via a first cable 15. N is an integer greater than 1. In this case, the preset port 123 and the radio remote unit 40 have multiple signal transmission paths, thereby transmitting multiple groups of radio frequency signals. For example, as shown in FIG3D , the preset port 123 may include two connectors 1231, and the antenna structure 10 may include two first cables 15 (as shown in FIG3B ) and at least two connectors 14 (as shown in FIG3A ). Each connector 1231 is electrically connected to a connector 14 via a first cable 15.

[0082] The above embodiment is shown in Figure 3D, which takes the antenna array component 12 as an example, which includes 8 radiating units 124 and 1 preset port 123. In other embodiments of the present application, the number of radiating units 124 can also be other numbers, and the number of preset ports 123 can also be other numbers.

[0083] For example, as shown in FIG3D , the number of preset ports 123 is at least two. The number of connectors 14 (shown in FIG3A ) and first cables 15 (shown in FIG3B ) is at least two. The number of second cables 30 (shown in FIG2 ) is at least two. The first cables 15 are connected to the corresponding preset ports 123, so that each preset port 123 is electrically connected to the connector 14 disposed in the second accommodating cavity 1311 (shown in FIG3A ) of the mounting base body 131 (shown in FIG3A ). Each connector 14 is further electrically connected to the radio remote unit 40 (shown in FIG2 ) via the corresponding second cable 30, thereby enabling each preset port 123 to exchange signals with the radio remote unit 40 via the corresponding first cable 15, connector 14, and second cable 30. Furthermore, the center point of the two preset ports 123 furthest apart is the first position, and the distance between the mounting base 13 (shown in FIG3A ) and the first position is less than the distance between the mounting base 13 and any of the preset ports 123. At this time, the mounting seat 13 is located between at least two preset ports 123, and the sum of the distances between the mounting seat 13 and the preset ports 123 is small, thereby reducing the total length of the required first cable 15 and achieving the purpose of reducing transmission loss.

[0084] In order to further reduce the transmission loss between the connector 14 and the preset port 123, as shown in Figure 5A, a mounting hole 1314 can be provided on the above-mentioned mounting seat body 131. The end of the connector 14 (as shown in Figure 3A) close to the antenna array assembly 12 (as shown in Figure 3B) can pass through the mounting hole 1314 and be electrically connected to the preset port 123. In this way, by providing the mounting hole 1314 near the preset port 123 on the mounting seat body 131, it is ensured that the connector 14 can be directly electrically connected to the preset port 123, thereby reducing the transmission loss. Alternatively, when it is necessary to connect the connector 14 and the preset port 123 through the first cable 15, the first cable 15 does not need to bypass the mounting seat body 131, nor does it need to extend into the second accommodating cavity 1311. It can be electrically connected to the connector 14 on the outside of the mounting seat body 131, thereby further reducing the length of the first cable 15 and achieving the purpose of further reducing the transmission loss of the first cable 15.

[0085] In some embodiments of the present application, as further shown in FIG5A , the second accommodating cavity 1311 of the mounting base body 131 may be a groove, with the opening of the groove facing away from the back surface. The side of the groove near the preset port 123 (as shown in FIG3C ) includes a first groove wall 1312, with a mounting hole 1314 defined therein. After one end of the connector 14 passes through the mounting hole 1314 in the first groove wall 1312, the end of the connector 14 extends beyond the sidewall of the groove and is electrically connected to the preset port 123. Because the first groove wall 1312 is located on the side of the groove near the preset port 123, the distance between the preset port 123 and the end of the connector 14 passing through the mounting hole 1314 is shortened, thereby reducing signal transmission loss between the preset port 123 and the connector 14.

[0086] On this basis, as shown in FIG5B , a first angle α is formed between the plane where the first groove wall 1312 is located and the back surface 122. The opening of the first angle α faces the preset port 123, and 0<α≤90°. For example, the first angle α can be 5°, 25°, 45°, 65°, 80°, 90°, etc. When the connector 14 needs to be electrically connected to the preset port 123 via the first cable 15, the opening of the first angle α between the first groove wall 1312 and the back surface 122 faces the preset port 123. That is, the preset port 123, the end of the connector 14 (as shown in FIG3A ) passing through the mounting hole 1314, and the first cable 15 (as shown in FIG3B ) used to connect the preset port 123 and the connector 14 are all located on the same side of the first groove wall 1312. In this case, the required length of the first cable 15 is relatively short.

[0087] When the first angle α is greater than 90°, as shown in FIG6 , the second end a2 of the first cable 15 must extend toward the back surface 122 (as shown in FIG3C ). When the first cable 15 is connected to the connector 14, it must first be bent away from the back surface 122 and then bent toward the back surface 122. This means that the first cable 15 must be bent at least twice. Furthermore, the angle δ of the first cable 15 after being bent at the connection with the connector 14 is small, resulting in a large degree of bending, which is inconvenient for installation and requires a long length of the first cable 15. Furthermore, the second cable 30 (as shown in FIG2 ) must also be bent at least twice when connected outward. Furthermore, the angle θ of the second cable 30 after being bent at the connection with the connector 14 is small, resulting in a large degree of bending, which is inconvenient for installation and requires a long length of the first cable 15.

[0088] When 0 < α < 90°, as shown in Figure 7 , the end of first groove wall 1312 away from rear surface 122 is inclined toward preset port 123. After one end of connector 14 passes through mounting hole 1314, its extension direction through mounting hole 1314 faces rear surface 122, while the second end a2 of first cable 15 for electrical connection to connector 14 extends away from rear surface 122. To electrically connect to connector 14, first cable 15 only needs to be bent once, away from rear surface 122. After the bend, the angle δ at the bend is large, the degree of bending is small, and the bending is easy. Furthermore, second cable 30 only needs to be bent once at the connection with connector 14, facilitating installation of second cable 30.

[0089] When α = 90°, as shown in Figure 8 , the first slot wall 1312 is perpendicular to the back surface 122, and the axis of the mounting hole 1314 in the first slot wall 1312 is parallel to the back surface 122. After one end of the connector 14 passes through the mounting hole 1314, the connector 14 extends parallel to the back surface 122. Furthermore, because the end of the connector 14 passing through the mounting hole 1314, the preset port 123, and the first cable 15 are all located on the same side of the first slot wall 1312, when the first cable 15 connects the connector 14 and the preset port 123, the second end a2 of the first cable 15 extends parallel to the back surface 122. In other words, the first cable 15 can be connected to the connector 14 without bending. Furthermore, the angle θ of the second cable 30 after bending at the connection with the connector 14 is large, the degree of bending is small, and bending is easy, facilitating installation of the second cable 30.

[0090] To summarize, in the antenna structure provided in the embodiment of the present application, the first angle α between the plane where the first groove wall 1312 is located and the back surface 122 satisfies 0<α≤90°. At this time, when the first cable 15 is connected to the connector 14, it does not need to be bent or only needs to be bent once, and the angle δ at the bending point is large, which facilitates the installation of the first cable 15 and the connector 14, and can reduce the length of the first cable 15, thereby achieving the purpose of improving the installation convenience of the antenna structure and reducing the transmission loss in the first cable 15.

[0091] Furthermore, as shown in Figure 5A, the above-mentioned groove has a second groove wall 1313, and a second angle β is formed between the first groove wall 1312 and the second groove wall 1313, and 45°≤β<180°; for example, the second angle β is 45°, 60°, 90°, 120°, 135°, 150°, 175°, etc.

[0092] When the second angle β between the first groove wall 1312 and the second groove wall 1313 is less than 45°, the groove opening is small. When the second cable 30 (as shown in FIG. 2 ) is inserted into the groove and connected to the connector, the operator's operating space is small and the connection operation is more difficult.

[0093] The second angle β between the first groove wall 1312 and the second groove wall 1313 in the antenna structure provided by the present application is larger, and the space at the open end of the groove is larger. When the second cable 30 is extended into the groove and connected to the connector 14, the staff has a larger operating space, which facilitates the installation and connection of the second cable 30 and the connector 14, and improves the convenience of installation and maintenance of the antenna structure and the second cable.

[0094] When multiple sets of RF signals need to be exchanged between the antenna array assembly 12 (as shown in FIG. 3C ) and the radio remote unit 40 (as shown in FIG. 2 ), or multiple signal transmission paths are required, the antenna structure 10 also requires multiple sets of connectors 14 (as shown in FIG. 3A ). In this case, if mounting holes 1314 are provided only on the first slot wall 1312 , the size of the mounting base body 131 may limit the number of mounting holes 1314 provided on the first slot wall 1312 to accommodate multiple connectors 14 .

[0095] To address this issue, as shown in FIG9 , a mounting hole 1314 can be defined in the second slot wall 1313 of the mounting base body 131. The ends of the connectors 14 located near the antenna array assembly 12 can be connected to the first cable 15 through the mounting holes 1314 in the first slot wall 1312 or the second slot wall 1313, respectively, ensuring that all connectors 14 can be electrically connected to the predetermined ports 123 (as shown in FIG3C ).

[0096] Alternatively, in other embodiments of the present application, the mounting seat body 131 may be as shown in FIG10 , with a mounting hole 1314 provided on the bottom of the groove, and the bottom of the groove is parallel to the back surface. The antenna structure 10 may be as shown in FIG11 , with the connector 14 (as shown in FIG3C ) being arranged at the bottom of the groove perpendicular to the back surface 122 (as shown in FIG3C ). When the groove has a relatively small depth, the connector 14 can be accommodated in the groove, thereby reducing the space occupied by the mounting seat body 131 and facilitating the arrangement and assembly of the internal components of the antenna structure 10. In addition, as shown in FIG4 , when the mounting seat 13 is located directly above the preset port 123, the connector 14 is perpendicular to the back surface 122, facilitating direct electrical connection of the connector 14 to the preset port 123.

[0097] On this basis, as shown in FIG10 , the groove has a plurality of groove walls, and the groove walls and the bottom have a third angle γ; wherein, 80°≤γ<100°; for example, the third angle γ is 80°, 85°, 90°, 95°, 100°. At this time, the groove wall and the bottom are close to vertical, and the shape of the groove is close to a rectangular parallelepiped. In the direction parallel to the back surface 122, the assembly space of the mounting seat 13 is limited, that is, when the projection area of ​​the mounting seat body 131 on the back surface 122 is the same, when the third angle between the groove wall and the bottom is within this range, the space of the groove is larger, and more connectors 14 can be accommodated, so that the groove can accommodate more connectors 14 to meet the transmission requirements of the radio frequency signal of the antenna array assembly 12 (as shown in FIG3C ).

[0098] Furthermore, to allow the mounting base body 131 to accommodate more connectors 14 and ensure that one end of the connector 14 can pass through the mounting hole 1314 to electrically connect to the predetermined port 123, as shown in FIG12 , the groove wall may be provided with a mounting hole 1314. The connectors 14 of the antenna structure 10 (as shown in FIG3A ) can be mounted to the bottom or the groove wall, allowing the groove to accommodate more connectors 14.

[0099] For the sake of convenience, the following description is based on an example in which the mounting seat body 131 of the mounting seat 13 is as shown in FIG. 5A and the second accommodating cavity 1311 is a groove.

[0100] Continuing with FIG5A , the mounting base 13 further includes a flange 133, which is fixedly disposed at the open end of the groove. At this point, the flange 133 is located around the open end of the groove and does not block the opening of the groove, thereby ensuring connection space between the connector 14 (as shown in FIG3A ) in the groove and the external cable (as shown in FIG2 ). Furthermore, the flange 133 is connected to the radome 11 (as shown in FIG3A ). For example, a hole can be drilled in the flange 133, and the flange 133 and the radome 11 can be relatively fixed by a connector. Alternatively, glue can be applied to the flange 133 so that the flange 133 and the radome 11 are bonded and fixed. Regardless of the method, the flange 133 can increase the area of ​​the connection between the mounting base 13 and the radome 11, making it easier to drill a hole or apply glue on the flange 133, thereby ensuring that the mounting base 13 is connected and installed to the radome 11.

[0101] To ensure the structural stability of the mounting base, as further shown in FIG5A , the mounting base 13 further includes a reinforcing rib 134 connected to at least one of the first groove wall 1312 and the second groove wall 1313. For example, the reinforcing rib 134 may be connected to the first groove wall 1312. Alternatively, the reinforcing rib 134 may be connected to the second groove wall 1313. Alternatively, the reinforcing rib 134 may be connected to the first groove wall 1312 and the second groove wall 1313. The reinforcing rib 134 increases the rigidity of the connection between the first groove wall 1312 and the second groove wall 1313, thereby improving the structural stability of the mounting base 13.

[0102] In addition, as shown in Figure 13, the mounting base 13 may include a mounting bracket 132. The mounting bracket 132 is relatively fixed to the mounting base body 131 to support the mounting base body 131. In addition, the mounting bracket 132 can be provided on a side of the mounting base body 131 close to the antenna array assembly 12, and the mounting bracket 132 is connected to the antenna array assembly 12. In this way, the mounting base body 131 can be relatively fixed to the antenna array assembly 12 through the mounting bracket 132. In addition, the mounting bracket 132 can also increase the distance between the mounting base body 131 and the antenna array assembly 12, so that the connector 14 (as shown in Figure 3A) in the second accommodating cavity 1311 (as shown in Figure 3B) is closer to the inner wall of the antenna cover 11, making it easier for the connector 14 to be connected to the second cable 30 (as shown in Figure 2) located on the outer wall side of the antenna cover 11.

[0103] Furthermore, as shown in FIG13 , the mounting bracket 132 may have an assembly space 1321 for accommodating the mounting seat body 131. The assembly space 1321 is a space enclosed by the skeleton of the mounting bracket 132. After the mounting seat body 131 is arranged in the assembly space 1321, the mounting bracket 132 can protect the mounting seat body 131. In particular, when the hardness of the mounting seat body 131 is relatively low, the mounting bracket 132 can prevent the mounting seat body 131 from being deformed due to stress during the assembly process of the antenna structure 10, thereby affecting the connection stability between the connector 14 (as shown in FIG3A ) and the mounting seat body 131, and further affecting the connection effect between the connector 14 and the preset port 123 (as shown in FIG3C ) or the second cable 30 (as shown in FIG2 ).

[0104] In addition, in the above-described embodiment, as shown in FIG16B , the mounting bracket 132 can be fixedly connected to the reflector 125, so that the mounting base 13 is relatively fixed to the reflector 125 of the antenna array assembly 12 within the first accommodating cavity 111, thereby preventing relative displacement between the antenna array assembly 12 and the mounting base 13 when the radome 11 is installed. For example, a bracket hole (not shown) is provided on the mounting bracket 132, and a threaded hole (not shown) is provided on the reflector 125. The mounting bracket 132 and the reflector 125 are screwed together with screws (not shown) passing through the bracket hole and threadedly connected to the threaded hole, thereby achieving a fixed connection between the mounting bracket 132 and the reflector 125.

[0105] On this basis, as shown in FIG14 , a first connection hole 112 can be provided on the antenna cover 11. The first connection hole 112 is connected to the second accommodating cavity 1311 (as shown in FIG3A ). The second cable (as shown in FIG3B ) used to connect the radio remote unit 40 (as shown in FIG2 ) and the connector 14 (as shown in FIG3A ) can pass through the first connection hole 112 and extend into the second accommodating cavity 1311 (as shown in FIG3A ), and then be electrically connected to the connector 14 in the second accommodating cavity 1311. Therefore, during installation or maintenance, there is no need to pull the connector 14 out of the antenna cover 11, which improves the convenience of installation and maintenance of the antenna structure.

[0106] Furthermore, as shown in Figure 15 , the inner wall of the radome 11 located on the side of the mounting base 13 facing away from the rear surface is a first inner wall 113. The distance between the end of the connector 14 facing away from the antenna array assembly 12 and the first inner wall 113 of the radome 11 is a first distance h1. The distance between the end surface of the mounting base 13 facing away from the rear surface 122 (as shown in Figure 3C ) and the first inner wall 113 is a second distance h2. Furthermore, h1 is greater than or equal to h2. In other words, after the connector 14 is installed in the second accommodating cavity 1311 of the mounting base body 131, the connector 14 never protrudes beyond the end surface of the mounting base 13. During assembly of the antenna structure 10, the mounting base 13 prevents direct contact between the connector 14 and the radome 11, thereby preventing friction between the connector 14 and the inner wall of the radome 11. This prevents passive intermodulation caused by repeated friction between the radome 11 and the connector 14 during assembly of the radome 11.

[0107] In any of the above embodiments, the connector 14 shown in FIG15 is sealedly connected to the mounting base body 131 at the mounting hole 1314 (as shown in FIG5A ). The groove at the mounting hole 1314 is ensured to be relatively sealed to the first accommodating cavity 111 (as shown in FIG3B ) of the radome 11 to prevent moist air in the groove from entering the first accommodating cavity 111 and affecting the performance of the antenna structure.

[0108] For example, the mounting seat body 131 is provided with a sealing ring (not shown in the figure) at the mounting hole 1314, and the sealing ring is sleeved on the end of the connector 14 close to the antenna array assembly 12, or, sealant is coated on the inner wall of the mounting hole 1314, and the end of the connector 14 close to the antenna array assembly 12 is sealed and connected to the inner wall of the mounting hole 1314 through the sealant.

[0109] In addition, the antenna structure 10 may include a waterproof member 16 as shown in FIG16A . The waterproof member 16 may be provided on the outside of the panel of the antenna cover 11 having the first connection hole 112 (as shown in FIG10 ) as shown in FIG16B .

[0110] As shown in Figure 16C , the waterproof member 16 may include a waterproof member body 161. The waterproof member body 161 is provided with a second connection hole 1611 (as shown in Figure 16A ). The second connection hole 1611 communicates with the first connection hole 112. The second cable 30 (as shown in Figure 2 ) can pass through the second connection hole 1611 and the first connection hole 112, respectively, to be electrically connected to the connector 14, thereby facilitating installation of the second cable 30.

[0111] Continuing with Figure 16C , the waterproof member 16 may include a boss 162. Boss 162 may be located on a side of the waterproof member body 161 near the mounting base 13. Furthermore, one end of boss 162 extends into the first connection hole 112 and abuts against the mounting base 13. This arrangement allows boss 162 to shield the connection between the mounting base 13 and the radome 11, thereby improving the waterproof performance of the connection.

[0112] On this basis, the antenna structure 10 shown in FIG16C may further include a first sealing member 101. The first sealing member 101 is disposed between the waterproof member 16 and the radome 11 to ensure a tight seal between the waterproof member 16 and the radome 11, thereby preventing moist air or rainwater from entering the first accommodating cavity 111 (as shown in FIG3B ) through the connection between the waterproof member 16 and the radome 11 and the connection between the radome 11 and the mounting base 13. For example, the first sealing member 101 may be a waterproof rubber strip or a sealing ring.

[0113] In addition, the antenna structure 10 shown in FIG16A further includes a second sealing member 102, which is disposed between the mounting base 13 and the radome 11 to ensure a tight seal between the mounting base 13 and the radome 11, thereby preventing humid air or rain from entering the first accommodating cavity 111 (shown in FIG3B ) through the connection between the radome 11 and the mounting base 13. For example, the second sealing member 102 may be a waterproof rubber strip or a sealing ring.

[0114] Furthermore, as shown in FIG16A , the antenna structure 10 may include a first connector 17. As shown in FIG5A , a first fixing hole 1331 may be provided on the flange 133 of the mounting base 13. As shown in FIG14 , a second fixing hole 114 is provided on the radome 11. At this point, the first connector 17 sequentially passes through the second fixing hole 114 and the first fixing hole 1331 and is fixedly connected to the flange 133 of the mounting base 13, thereby applying a force to move the mounting base 13 and the radome 11 closer together, thereby relatively fixing the mounting base 13 and the radome 11. At the same time, the second sealing member 102 is squeezed (as shown in FIG16C ), thereby improving the sealing performance of the connection between the mounting base 13 and the radome 11.

[0115] For example, the first connecting member 17 can be a bolt or a screw, and the first fixing hole 1331 can be a threaded hole. The first connecting member 17 passes through the second fixing hole 114 and is threadedly connected to the first fixing hole 1331, thereby ensuring that the mounting base 13 is fixedly connected to the antenna cover 11.

[0116] Alternatively, the first connecting member 17 is a pin, and the first fixing hole 1331 is a pin hole. After passing through the second fixing hole 114, the first connecting member 17 is connected with the first fixing hole 1331 by interference fit, thereby ensuring that the mounting base 13 is fixedly connected to the antenna cover 11.

[0117] On this basis, as shown in Figure 16A, a through hole 1612 is opened on the above-mentioned waterproof component 16, and the first connecting component 17 passes through the through hole 1612, the second fixing hole 114 and the first fixing hole 1331 on the waterproof component 16 in sequence, and is fixedly connected to the flange 133 of the mounting seat 13, thereby applying a force to the waterproof component 16 and the antenna cover 11 to move closer to each other, so that the waterproof component 16 and the antenna cover 11 are relatively fixed, and at the same time squeeze the first sealing component 101 (as shown in Figure 16C) to improve the sealing of the connection between the waterproof component 16 and the antenna cover 11.

[0118] In addition, in the above embodiment, the circumference of the first connecting member 17 may be coated with sealant to ensure the sealing between the first connecting member 17 and the first fixing hole 1331 or the second fixing hole 114 .

[0119] In other embodiments of the present application, the remote radio unit 40 of the communication device 02 may be disposed on a side wall of the antenna structure 10 near the communication bracket 20, as shown in FIG17 . This reduces the distance between the remote radio unit 40 and the antenna structure 10, shortens the length of the second cable 30 connecting the remote radio unit 40 and the antenna structure 10, and thereby reduces signal transmission loss in the second cable 30.

[0120] Based on this, in some embodiments of the present application, the antenna structure 10 may include a support frame 18 and a second connector 19, as shown in FIG18 . Furthermore, a third fixing hole 115 is provided on the radome 11, as shown in FIG14 . Continuing with FIG18 , one end of the second connector 19 passes through the third fixing hole 115 and is fixedly connected to the support frame 18, while the other end of the second connector 19 is fixedly connected to the RF remote unit 40. In this way, the RF remote unit 40 is relatively fixed to the support frame 18, and the support frame 18 and the second connector 19 provide support and fixation for the RF remote unit 40, ensuring that the RF remote unit 40 is stably disposed on the side wall of the radome 11.

[0121] For example, a threaded hole can be opened on the support frame 18, and the second connecting member 19 is a bolt or a screw. The second connecting member 19 passes through the third fixing hole 115 and is threadedly connected to the threaded hole on the support frame 18 to achieve the purpose of relative fixation between the second connecting member 19 and the support frame 18.

[0122] Alternatively, a pin hole may be provided on the support frame 18, and the second connecting member 19 may be a pin. After the second connecting member 19 passes through the third fixing hole 115, it is interference fit with the pin hole on the support frame 18, thereby achieving the purpose of relative fixation of the second connecting member 19 and the support frame 18.

[0123] Of course, as shown in Figure 18 , the mounting base 13 can also be connected to the support frame 18, which is then connected to the antenna array assembly 12. In this case, the support frame 18 is connected to the antenna array assembly 12 and fixed relative to it. The mounting base 13 is connected to the support frame 18 and fixed relative to it. This ensures that the mounting base 13 and the antenna array assembly 12 are relatively fixed, ensuring a stable connection between the mounting base 13 and the antenna array assembly 12.

[0124] The above embodiment, as shown in FIG. 18 , takes the antenna structure 10 as an example, in which it includes four second connecting members 19 . In other embodiments of the present application, the number of the second connecting members 19 may also be other numbers.

[0125] Furthermore, as shown in FIG18 , the communication device 02 may further include a support base 50 disposed on the outer wall of the antenna structure 10. The support base 50 is provided with a fourth fixing hole 51. The second connector 19 passes through the fourth fixing hole 51 and the third fixing hole 115, respectively, to be fixed relative to the support frame 18, thereby relatively fixing the support base 50, the second connector 19, and the support frame 18. Furthermore, the support base 50 is connected to the radio remote unit 40, so that the radio remote unit 40 is relatively fixedly connected to the support base 50, the second connector 19, and the support frame 18. Ultimately, the radio remote unit 40 is fixedly mounted on the antenna structure 10, and the connection between the radio remote unit 40 and the antenna structure 10 is securely secured.

[0126] The above embodiment, as shown in FIG. 18 , takes the communication device 02 as an example, which includes two support bases 50 . In other embodiments of the present application, the number of support bases 50 may also be other numbers.

[0127] The above is only a specific embodiment of the present application, but the scope of protection of this application is not limited to this. Any changes or substitutions within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
