Description

Technical Field

[0001] The present invention relates to the field of radio communication technology, and in particular to an antenna structure and communication equipment. Background Art

[0002] The antenna structure is a key part in the wireless communication system, and the performance of the antenna structure directly determines the communication quality of the wireless system.

[0003] In a traditional antenna structure, the connector of the antenna structure is installed at the bottom of the antenna structure and transmits RF signals with the antenna array. The antenna structure is vertically hung on a pole, and the remote radio unit (RRU) is connected to the connector of the antenna structure through a jumper to achieve RF signal transmission.

[0004] However, in the traditional antenna structure, the connector is far away from the antenna array signal connection port, which will cause large transmission loss. Summary of the invention

[0005] The object of the present invention is to provide an antenna structure and a communication device for reducing transmission loss in the antenna structure.

[0006] In order to achieve the above purpose, the embodiment of the present application adopts the following technical solution:

[0007] In one aspect of an embodiment of the present application, an antenna structure is provided, which includes: an antenna cover, an antenna array assembly, a mounting seat, and a connector. The antenna cover has a first accommodating cavity, the antenna array assembly and the mounting seat are both arranged in the first accommodating cavity, the antenna array assembly has a radiation surface and a back surface facing away from the radiation surface, and the antenna array assembly has a preset port. The mounting seat includes a mounting seat body, and the mounting seat is located on the side where the back surface of the antenna array assembly is located, and a second accommodating cavity is arranged on the mounting seat body, the connector is arranged in the second accommodating cavity, and the connector is electrically connected to the preset port.

[0008] As can be seen from the above, the antenna array assembly has a radiation surface and a preset port. The connector is electrically connected to the preset port, and by transmitting a radio frequency signal to the connector, the radio frequency signal is transmitted to the preset port through the connector, so that the antenna array assembly transmits radio waves through the radiation surface, thereby enabling the antenna structure to transmit radio waves. Alternatively, after the radiation surface of the antenna array assembly receives the radio wave signal, the antenna array assembly transmits the radio frequency signal to the connector through the preset port, and transmits it to the outside of the antenna structure through the connector, thereby enabling the antenna structure to receive the radio wave signal. Therefore, when the connector is electrically connected to the preset port, the external device can transmit the radio frequency signal to the preset port of the antenna array assembly through the connector, so that the antenna array assembly transmits radio waves through the radiation surface. At the same time, after the radiation surface of the antenna array assembly receives the radio wave signal, the antenna array assembly transmits the radio frequency signal to the connector through the preset port, and transmits the radio frequency signal to the external device through the connector, so as to complete the radio frequency signal exchange between the antenna array assembly and the external device. In addition, the above antenna structure may also include a mounting seat. The mounting seat may be located in the first accommodating cavity, and the mounting body of the mounting seat has a second accommodating cavity capable of accommodating the connector, so that the mounting seat can accommodate and protect the connector. The antenna array assembly and the mounting seat are located in the first accommodating cavity of the antenna cover, so that the antenna array assembly and the mounting seat can be protected by the antenna cover to reduce the impact of the external environment on the antenna array assembly and the mounting seat. In this case, the antenna structure provided by the present application sets the connector in the second accommodating cavity of the mounting seat body. Since the mounting seat body is located in the first accommodating cavity, the connector is located in the first accommodating cavity. In addition, by fixing the mounting seat on the side where the back of the antenna array assembly is located, the connector can be located on the back of the antenna array assembly. At this time, the distance between the connector and the preset port of the antenna array assembly is small. In addition, the setting position of the mounting seat can be adjusted so that the mounting seat is set near the preset port, thereby reducing the distance between the connector and the preset port, and then reducing the signal transmission loss between the connector and the preset port. In the related art, the connector is set at the bottom of the antenna structure, the distance between the connector and the preset port is large, and the loss during signal transmission is large. The distance between the connector and the preset port in the antenna structure provided in the embodiment of the present application is small, so the transmission loss between the connector and the preset port can be reduced. The purpose of reducing the transmission loss in the antenna structure is achieved.

[0009] 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 placed close to the preset port, so that the connector and the preset port can be directly electrically connected. At this time, 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. The purpose of further reducing the transmission loss in the antenna structure is achieved.

[0010] In some other embodiments of the present application, the antenna structure may further include a first cable, the first cable is arranged in the first accommodating cavity, and the first end of the first cable is electrically connected to the preset port, and the second end of the first cable is electrically connected to the connector. When the mounting seat is limited by the installation space on the side where the back of the antenna array is located and cannot be installed near the preset port, so that the connector and the preset port cannot be directly electrically connected, the connector and the preset port can be electrically connected through the first cable. At this time, the radio frequency signal can be transmitted between the connector and the preset port through the first cable. In addition, the connector and the first cable for electrically connecting the connector and the preset port of the antenna array assembly are both located on the back of the antenna array assembly. In this way, the first cable and the connector are located on the same side of the antenna array assembly, which can achieve the purpose of reducing the length of the first cable. In the related art, the connector is arranged at the bottom of the antenna structure, that is, the length of the feeder used to electrically connect the connector to the preset port needs to be greater than the distance from the bottom of the antenna cover to the preset port, so the feeder length is longer and the transmission loss is larger. In the antenna structure provided in the embodiment of the present application, the mounting seat can be arranged near the preset port, thereby reducing the distance between the connector and the preset port, reducing the required length of the first cable, and achieving the purpose of reducing the transmission loss in the antenna structure. In some embodiments of the present application, a mounting hole may be provided on the mounting seat body. One 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.

[0011] 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; 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 short, and the transmission loss between the preset port and the connector is small, and the preset port further reduces the transmission loss inside the antenna structure.

[0012] 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 the 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 for connecting the preset port and the connector are all located on the same side of the first groove wall, and at this time, 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 back side. Because the end of the connector passing through the mounting hole, the preset port and the first cable are all located on the same side of the first slot wall, at this time, when the first cable is connected to the connector and the preset port, the extension direction of the second end of the first cable is parallel to the back side. 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 back side is inclined toward the preset port. After one end of the connector passes through the mounting hole, the extension direction of the end passing through the mounting hole is toward the back side, and the extension direction of the second end of the first cable for electrical connection with the connector is away from the back side. At this time, the first cable only needs to be bent once in the direction away from the back side, and after bending, the angle at the bending point is greater than 90°, the bending degree is small, and it is easier to bend. When the first angle α is greater than 90°, the extension direction of the second end of the first cable needs to be toward the back. When the first cable is connected to the preset port and the connector, it needs to be bent in the direction away from the back first, and then bend in the direction toward the back, that is, the first cable needs to be bent at least twice, and the angle of the first cable after being bent at the connection with the connector is small, the bending degree is large, and it is not convenient to install. At the same time, the required length of the first cable is long. Therefore, when the first cable in the antenna structure provided in the embodiment of the present application is connected to the connector, it does not need to be bent or only needs to be bent once, and the angle at the bending point is large, which is convenient for the installation of the first cable and the connector, and can reduce the length of the first cable, thereby achieving the purpose of improving the convenience of installation of the antenna structure and reducing the transmission loss in the first cable.

[0013] In some embodiments of the present application, the groove may have a second groove wall, and a second angle β is formed between the first groove wall and the second groove wall; wherein 45°≤β<180°; for example, the second angle β is 45°, 60°, 90°, 120°, 135°, 150°, 175°, etc. At this time, the opening of the second angle between the first groove wall and the second groove wall is larger, and when the external cable is inserted into the groove and connected to the connector, the operator has a larger operability space, which is convenient for the installation of the external cable and the connector. In the case where the groove has the same groove depth, when the second angle β between the first groove wall and the second groove wall is less than 45°, the groove opening is smaller, and when the external cable is inserted into the groove and connected to the connector, the operator has a smaller operability space and the connection is more difficult. Therefore, the antenna structure provided in the embodiment of the present application is more convenient for the installation of the external cable and the connector, so as to achieve the purpose of improving the installation and maintenance convenience of the antenna structure and the external cable.

[0014] In some embodiments of the present application, a mounting hole is provided on the second groove wall. When there are multiple groups of RF signals exchanged between the preset port and the external device, the antenna structure requires a large number of connectors, and different connectors can pass through the mounting holes provided on the first groove wall or the second groove wall and be electrically connected to the preset port, ensuring that the number of connectors that can be accommodated in the groove meets the demand.

[0015] In some embodiments of the present application, the mounting seat may further include a reinforcing rib, which is disposed between the first slot wall and the second slot wall, and the reinforcing rib is connected to at least one of the first slot wall and the second slot wall. The reinforcing rib can improve the connection rigidity between the first slot wall and the second slot wall, thereby achieving the purpose of improving the structural stability of the mounting seat.

[0016] In some embodiments of the present application, the second accommodating cavity can be a groove, the opening of the groove is away from the back side; a mounting hole is provided on the bottom of the groove, and the bottom of the groove is parallel to the back side. In this case, the axis of the mounting hole provided at the bottom of the groove is perpendicular to the back side. After one end of the connector passes through the mounting hole, the connector extends in a direction perpendicular to the back side, and the connector is arranged at the bottom of the groove. When the installation space of the mounting seat is small, the groove can accommodate the connector in the groove when it has a small depth.

[0017] In some embodiments of the present application, the groove may have a plurality of groove walls, and the groove wall 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 projection area of ​​the bottom of the groove and the open end of the groove on the back side is relatively close or the same. In the direction parallel to the back side, when the assembly space of the mounting seat is limited, that is, when the projection area of ​​the mounting seat body on the back side is the same, when 80°≤γ<100°, the space of the groove is larger, and more connectors can be accommodated, ensuring that the number of connectors that can be accommodated in the groove meets the demand. When the third angle γ is less than 80° or greater than 100°, the inclination of the groove wall is larger, and when the projection area of ​​the mounting seat body on the back side 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.

[0018] 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. When the antenna structure requires a large number of connectors, the connectors can be installed on the bottom or the groove wall respectively to ensure that the number of connectors that can be accommodated in the groove meets the requirements.

[0019] In some embodiments of the present application, the connector and the mounting seat body can be sealed and connected at the mounting hole; for example, the mounting seat body is provided with a sealing ring at the mounting hole, and the sealing ring is sleeved on the end of the connector close to the antenna array assembly, or a sealant is applied on the inner wall of the mounting hole, and the end of the connector close to the antenna array assembly is sealed and connected to the inner wall of the mounting hole through the sealant. At this time, the second accommodating cavity of the mounting seat body is relatively sealed with the first accommodating cavity of the antenna cover at the mounting hole to prevent the humid air in the second accommodating cavity from entering the first accommodating cavity, causing corrosion of the components in the first accommodating cavity, and ensuring that the performance of the antenna structure is not affected. In order to achieve the purpose of improving the working stability and service life of the antenna structure.

[0020] In some embodiments of the present application, the mounting seat may further include a mounting bracket, which may be disposed on the side of the mounting seat body facing the back, one end of the mounting bracket being connected to the mounting seat body, and the other end of the mounting bracket being connected to the antenna array assembly. The mounting bracket is respectively connected to the mounting seat body and the antenna array assembly, and the mounting seat body and the antenna array assembly are relatively fixed by the mounting bracket. At this time, the mounting bracket can support the mounting seat body, and at the same time, the mounting bracket can increase the distance between the mounting seat body and the back of the antenna array assembly, ensuring that the connector in the first accommodating cavity is close to the inner wall of the antenna cover facing away from the back, so as to facilitate the connection and installation of the connector with the external cable.

[0021] In some embodiments of the present application, the mounting bracket may have an assembly space, and the mounting seat body is disposed in the assembly space, wherein the assembly space may be a space surrounded by a frame of the mounting bracket. After the mounting seat body is disposed in the assembly space, the mounting bracket can protect the mounting seat body, preventing the mounting seat body from being deformed by force, thereby affecting the connection stability between the connector and the mounting seat body.

[0022] In some embodiments of the present application, the second accommodating cavity can be a groove, and the opening of the groove faces away from the back; the mounting seat can also include a flange, which is fixedly arranged at the opening end of the groove, and the flange is connected to the antenna cover. In this case, the mounting seat body can be fixedly connected to the antenna cover through the flange. Moreover, the flange is arranged on the peripheral side of the opening end of the groove, and will not block the opening of the groove, thereby ensuring the connection space between the connector in the groove and the external cable. In addition, the flange can increase the area of ​​the connection between the mounting seat and the antenna cover, which is convenient for opening holes or applying glue on the flange to ensure that the mounting seat and the antenna cover are relatively fixed.

[0023] In some embodiments of the present application, a first connection hole may be provided on the antenna cover, and the first connection hole is connected to the second accommodating cavity. In this case, the external cable can pass through the first connection hole and be electrically connected to the connector in the second accommodating cavity, thereby improving the installation convenience of the external cable. In addition, when connecting the external cable, there is no need to pull the connector out of the antenna cover, and the installation is simple and convenient.

[0024] 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 arranged on the waterproof component body, and the second connection hole is connected to the first connection hole. The boss is arranged 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 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.

[0025] In some embodiments of the present application, the antenna structure may further include a first sealing member, which is disposed between the waterproof member and the antenna cover. By way of example, the first sealing member is a waterproof rubber strip or a sealing ring. The first sealing member ensures the sealing between the waterproof member and the antenna cover, prevents humid air or rainwater from entering the connection between the antenna cover and the mounting seat through the connection between the waterproof member and the antenna cover, and finally enters the first accommodating cavity, thereby protecting the components in the first accommodating cavity from being corroded by humid air or rainwater, which may affect the working performance of the antenna structure. This is to achieve the purpose of improving the working stability and service life of the antenna structure.

[0026] In some embodiments of the present application, the antenna structure may further include a second sealant, which is disposed between the mounting seat and the antenna cover. By way of example, the second sealant is a waterproof rubber strip or a sealing ring. The second sealant ensures the sealing between the mounting seat and the antenna cover, prevents humid air or rain from entering the first accommodating cavity through the connection between the antenna cover and the mounting seat, and protects the components in the first accommodating cavity from being corroded by humid air or rain, thereby affecting the working performance of the antenna structure. This is to achieve the purpose of improving the working stability and service life of the antenna structure.

[0027] In some embodiments of the present application, the antenna structure may further include a first connector. A first fixing hole may be provided on the mounting seat, and a second fixing hole may be provided on the antenna cover. The first connector passes through the second fixing hole and the first fixing hole in sequence and is fixedly connected to the mounting seat. For example, the first connector is a bolt or a screw, and the first fixing hole is a threaded hole. After the first connector passes through the second fixing hole, it is threadedly connected to the first fixing hole, thereby ensuring that the mounting seat and the antenna cover are fixedly connected. Alternatively, the first connector is a pin, and the first fixing hole is a pin hole. After the first connector passes through the second fixing hole, it is connected to the first fixing hole by interference fit, thereby ensuring that the mounting seat and the antenna cover are fixedly connected. After the first connector is fixedly connected to the mounting seat, a force that approaches each other can be applied to the mounting seat and the antenna cover to ensure that the mounting seat and the antenna cover are relatively fixed, and at the same time, the mounting seat and the antenna cover fit more closely, thereby improving the sealing of the connection between the mounting seat and the antenna cover.

[0028] In some embodiments of the present application, the antenna array assembly may include a reflector and a plurality of radiating units arranged in an array, the radiating surface of the antenna array assembly is the end surface of the radiating unit away from the reflector, and the reflector has a reflecting surface close to the radiating surface. The radiating unit can emit or receive radio waves, and the reflecting surface of the reflector can reflect the radio waves, so that the radio waves are concentrated on the receiving point of the radiating unit, thereby enhancing the receiving ability of the radiating unit. In addition, the back of the antenna array assembly is the end surface of the reflector away from the radiating surface, and the preset port is arranged on the end surface of the reflector away from the radiating surface. The antenna array assembly may also include a feeding network, the feeding network is electrically connected to the radiating unit, and the feeding network is electrically connected to the preset port. After the radiating unit receives the radio wave, the RF signal is transmitted to the preset port through the feeding network, and then transmitted to the outside of the antenna array assembly through the preset port, or the external transmits the RF signal to the preset port, and then transmits it to the radiating unit through the feeding network. After receiving the RF 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.

[0029] 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 antenna cover is a first distance h1, and the distance between the end face of the mounting seat away from the back and the first inner wall is a second distance h2, and h1 ≥ h2. The first inner wall is the inner wall of the antenna cover on the side of the mounting seat away from the back. At this time, the end of the connector facing away from the antenna array assembly does not protrude from the end face of the mounting seat. When the antenna cover is placed on the assembled antenna array, reflector, mounting seat and connector assembly, the connector will not generate friction with the inner wall of the antenna cover, thereby preventing the problem of passive inter modulation (PIM) caused by repeated friction between the antenna cover and the connector during the assembly of the antenna cover. In addition, the mounting seat will protect the connector and further protect the connector.

[0030] In some embodiments of the present application, the number of preset ports is at least two, the number of first cables is at least two, the center point of the two preset ports farthest apart is the first position, the distance between the mounting seat and the first position is the first length, and the above-mentioned first length is less than the distance between the mounting seat and any preset port. When the number of preset ports is at least two, the distance between the mounting seat and the first position is less than the distance from any preset port, that is, the mounting seat is located in the middle of at least two preset ports. At this time, the sum of the distances between the mounting seat and the preset ports is small, thereby reducing the total length of the required first cable, thereby achieving the purpose of reducing transmission loss.

[0031] 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 groups 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 be electrically connected to the outside, so that the preset port has multiple signal transmission paths with the outside, thereby transmitting multiple groups of radio frequency signals.

[0032] Another aspect of an embodiment of the present application provides a communication device, which may include any of the above-mentioned antenna structures, and the communication device may also include a communication bracket, a second cable, and a radio frequency remote unit. The antenna structure and the radio frequency remote unit are respectively arranged on the communication bracket. One end of the second cable is electrically connected to an end of the connector of the antenna structure away from the antenna array assembly, and the other end of the second cable is electrically connected to the radio frequency remote unit. The above-mentioned communication device has the same technical effect as the antenna structure provided in the above-mentioned embodiment, which will not be repeated here.

[0033] In some embodiments of the present application, the radio remote unit is disposed on the outer wall of the antenna cover of the antenna structure. In this case, the distance between the radio remote unit and the connector is small, and when the connector and the radio remote unit are electrically connected through the second cable, the length of the second cable required is small, thereby reducing the transmission loss of the second cable. This reduces the transmission loss of the radio frequency signal between the antenna structure and the radio remote unit.

[0034] In some embodiments of the present application, the antenna structure may further include a support frame and a second connector disposed in the first accommodating cavity. In addition, a third fixing hole is provided on the antenna cover. One end of the second connector passes through the third fixing hole and is connected to the support frame, and the other end of the second connector is connected to the radio frequency remote unit. At this time, the radio frequency remote unit is connected to the support frame through the second connector and is relatively fixed, and the support frame provides a supporting and fixing function for the radio frequency remote unit, so that the radio frequency remote unit can be stably arranged on the side wall of the antenna cover.

[0035] In some embodiments of the present application, the antenna structure may further include a support seat, which is disposed on the outer wall of the antenna cover on the side of the mounting seat away from the back, and is connected to the radio frequency remote unit. In addition, a fourth fixing hole is disposed on the support seat, and one end of the second connecting member passes through the fourth fixing hole and the third fixing hole in sequence and is connected to the support frame. After the second connecting member passes through the fourth fixing hole and the third fixing hole and is connected to the support frame, the support seat, the antenna cover and the support frame are relatively fixed, and then the radio frequency remote unit is connected to the support seat, thereby fixing the radio frequency remote unit on the outer wall of the antenna cover.

[0069] In the case where the above-mentioned communication device 02 is a base station, in some embodiments of the present application, the communication device 02 may include Figure 2 The antenna structure 10, the communication bracket 20, the second cable 30 and the radio frequency remote unit 40 are shown. The antenna structure 10 and the radio frequency remote unit 40 are respectively arranged on the communication bracket 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 radio frequency remote unit 40. The antenna structure 10 transmits signals with the radio frequency remote unit 40 through the second cable 30, and the radio frequency remote unit 40 is used to transmit radio frequency signals.

[0070] For example, the communication bracket 20 may include a pole 21, and the pole 21 may fix and support the antenna structure 10. In addition, the communication bracket 20 may also include an adjustment arm 22 and a clamp 23, wherein 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 may be connected to the pole 21 through the adjustment arm 22 and the clamp 23 in sequence, and the adjustment arm 22 may adjust the pitch angle of the antenna structure 10 relative to the pole 21.

[0071] The above embodiment Figure 2 As shown, the radio remote unit 40 is set on the pole 21 as an example. In other embodiments of the present application, the radio remote unit 40 can also be set on a tower, a rooftop, or other location close to the antenna structure 10.

[0072] Based on this, in some embodiments of the present application, the antenna structure 10 is as follows Figure 3A The antenna shown may include a radome 11, a connector 14 and a mounting seat 13, wherein the mounting seat 13 includes a mounting seat body 131. The mounting seat body 131 has a second accommodating cavity 1311 for accommodating the connector 14. After the connector 14 is arranged in the second accommodating cavity 1311, the mounting seat body 131 can accommodate and protect the connector 14. On this basis, Figure 3AThe connector 14 shown may be an MQ quick-connect connector or a DIN connector.

[0073] The antenna structure 10 is as follows Figure 3B or Figure 4 The antenna structure 10 may include an antenna array assembly 12. The antenna cover 11 has a first accommodating cavity 111 for accommodating the antenna array assembly 12 and the mounting seat 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 seat 13 arranged in the first accommodating cavity 111.

[0074] like Figure 3C As shown, the antenna array assembly 12 has a radiation surface 121, a back surface 122 facing away from the radiation surface 121, and a preset port 123 located on the back surface 122. The antenna array assembly 12 can receive radio waves through the radiation surface 121, and send 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 radiation surface 121. In order to facilitate the antenna array assembly 12 to transmit radio wave signals received from different areas of the radiation surface 121 to the outside through the preset port 123, according to the distribution of each component in the antenna structure 10, the preset port 123 can be set at a position close to the center of the back surface 122. At this time, the preset port 123 is electrically connected to the connector 14, and the radio frequency signal is transmitted to the connector 14 through the connector 14. The radio frequency signal is transmitted to the preset port 123 of the antenna array assembly 12, so that the antenna array assembly 12 transmits radio waves through the radiation surface 121, thereby enabling the antenna structure 10 to transmit radio waves. When the antenna array assembly 12 receives radio waves through the radiation surface 121, the antenna array assembly 12 transmits the radio frequency signal to the connector 14 through the preset port 123, and transmits the radio frequency signal to the radio remote unit 40 (such as Figure 2 As shown in FIG. 1 , the antenna structure 10 can 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 the transmission loss in the antenna structure is achieved.

[0075] In some embodiments of the present application, Figure 4 As shown, one end of the connector 14 close to the antenna array assembly 12 is connected to the preset port 123 (such as Figure 3CIn the related art, the connector arranged 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 longer and the transmission loss is larger. 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 the radio frequency is transmitted between the preset port 123 and the connector 14, no path loss is generated. The purpose of further reducing the transmission loss within the antenna structure 10 is achieved.

[0076] In other embodiments of the present application, the antenna structure 10 is as follows: Figure 3B As shown, the first cable 15 may be disposed in the first accommodation cavity 111. 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 (such as Figure 3A At this time, Figure 3C As shown, 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, so as to achieve the purpose of reducing the transmission loss in the antenna structure 10. On this basis, continue as Figure 3C As shown, 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, which can radiate or receive radio waves. The radiating surface 121 of the antenna array assembly 12 is the radiating surface of the radiator of the radiating unit 124, and the back of the antenna array assembly 12 is the end face of the reflector 125 away from the radiating surface 121. Of course, the components of the antenna array assembly 12 away from the radiating surface 121 may also protrude from the back face 122. In addition, the reflector 125 also has a reflecting surface, which is the end face facing the radiating surface 121. When the radiating unit 124 receives radio waves, the reflecting surface of the reflector 125 can reflect the radio waves, so that the radio waves are gathered at the receiving point of the radiating unit 124, thereby enhancing the receiving ability of the radiating 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 radiating unit 124.

[0077] In addition, if Figure 3DAs shown, the antenna array assembly 12 may also include a feed network 126, which is electrically connected to the radiator of the radiating unit 124, and at the same time, the feed network 126 is electrically connected to the preset port 123. That is, the radiator of each radiating unit 124 is electrically connected to the preset port 123 through the feed network 126. When any radiator of the radiating unit 124 receives radio waves, it can transmit the RF signal to the preset port 123 through the feed network 126, and the preset port 123 then transmits it to the RF remote unit 40 through the first cable 15 and the connector 14. When it is necessary to transmit radio waves through the radiator of the radiating unit 124, the RF remote unit 40 transmits the RF signal to the connector 14, and after being transmitted to the preset port 123 through the connector 14 and the first cable 15, the RF signal is distributed and transmitted to the radiators of multiple radiating units 124 through the feed network 126, and the radiators emit radio waves outward. Finally, the antenna structure receives or transmits radio waves and transmits RF signals with the RF remote unit 40.

[0078] When the antenna array assembly 12 needs to communicate with the radio remote unit 40 (such as Figure 2 When transmission is performed through a set of signal transmission paths (as shown), the preset port 123 may include a connector 1231, and the antenna structure 10 may include a connector 14, 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.

[0079] Alternatively, when the antenna array assembly 12 needs to communicate with the radio remote unit 40 (eg Figure 2 When transmitting 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 is electrically connected to a connector 1231, or each connector 14 is electrically connected to a connector 1231 through a first cable 15. Wherein N is an integer greater than 1. At this time, the preset port 123 and the radio frequency remote unit 40 have multiple signal transmission paths, so as to transmit multiple groups of radio frequency signals. Exemplarily, continue as Figure 3D As shown, the preset port 123 may include two connectors 1231, and the antenna structure 10 may include two first cables 15 (such as Figure 3B as shown) and at least two connectors 14 (as Figure 3A Each connector 1231 is electrically connected to a connector 14 via a first cable 15.

[0080] The above embodiment Figure 3DAs shown, the antenna array component 12 includes 8 radiation units 124 and 1 preset port 123 as an example. In other embodiments of the present application, the number of radiation units 124 may be other numbers, and the number of preset ports 123 may be other numbers.

[0081] For example, Figure 3D The number of the preset ports 123 shown is at least two. Figure 3A As shown) and the first cable 15 (as Figure 3B The number of the second cables 30 (as shown) is at least two. Figure 2 The number of the first cables 15 is at least two. The first cables 15 are connected to the preset ports 123 respectively, so that each preset port 123 is connected to the mounting seat body 131 (as shown in FIG. Figure 3A The second accommodating cavity 1311 (as shown) Figure 3A Each connector 14 is electrically connected to a radio remote unit 40 (as shown in FIG. 1 ) through a corresponding second cable 30. Figure 2 As shown in FIG. 1 , each preset port 123 is electrically connected to the radio remote unit 40 through the corresponding first cable 15, connector 14 and second cable 30. In addition, the center point of the two preset ports 123 farthest apart is the first position, and the mounting base 13 (as shown in FIG. Figure 3A The distance between the mounting seat 13 and the first position is less than the distance between the mounting seat 13 and any preset port 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 first cable 15 required, thereby achieving the purpose of reducing transmission loss.

[0082] In order to further reduce the transmission loss between the connector 14 and the preset port 123, as shown in FIG. Figure 5A As shown, the mounting seat body 131 may be provided with a mounting hole 1314. Figure 3A as shown) close to the antenna array assembly 12 (as shown Figure 3B One end of the connector 124 (as shown) can pass through the mounting hole 1314 and be electrically connected to the preset port 123. In this way, by opening the mounting hole 1314 near the preset port 123 at 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.

[0083] In some embodiments of the present application, continue as Figure 5A As shown, the second accommodating cavity 1311 of the mounting seat body 131 may be a groove, the opening of the groove faces away from the back; the groove is close to the preset port 123 (such as Figure 3C The first groove wall 1312 is provided on one side of the groove (as shown in FIG. 1 ), and a mounting hole 1314 is provided on the first groove wall 1312. After one end of the connector 14 passes through the mounting hole 1314 on the first groove wall 1312, the one end of the connector 14 exceeds the side wall 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 close to the preset port 123, at this time, the distance between the preset port 123 and the end of the connector 14 passing through the mounting hole 1314 is small, thereby reducing the signal transmission loss between the preset port 123 and the connector 14.

[0084] On this basis, if Figure 5B As shown, a first angle α is formed between the plane where the first groove wall 1312 is located and the back surface 122, and 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 through 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 connector 14 (such as Figure 3A ) passing through one end of the mounting hole 1314 and a first cable 15 (as shown in FIG. 1 ) for connecting the preset port 123 and the connector 14 Figure 3B As shown in the figure, both are located on the same side of the first slot wall 1312. In this case, the required length of the first cable 15 is shorter.

[0085] When the first angle α is greater than 90°, Figure 6 As shown, the extension direction of the second end a2 of the first cable 15 needs to be toward the back side 122 (eg Figure 3C As shown in FIG. 1 ), when the first cable 15 is connected to the connector 14, it needs to be bent away from the back surface 122 first, and then bent toward the back surface 122. That is, the first cable 15 needs to be bent at least twice, and the angle δ of the first cable 15 after being bent at the connection with the connector 14 is small, and the bending degree is large, which is not convenient for installation and the required length of the first cable 15 is long. In addition, the second cable 30 (as shown in FIG. Figure 2 When the second cable 30 is connected outwardly (as shown), it also needs to be bent at least twice, and the angle θ after bending at the connection between the second cable 30 and the connector 14 is small, and the bending degree is large, which is not convenient for the installation of the second cable 30 and the connector 14.

[0086] When 0<α<90°, Figure 7As shown, the end of the first groove wall 1312 away from the back 122 is inclined toward the preset port 123. After one end of the connector 14 passes through the mounting hole 1314, the extension direction of the end passing through the mounting hole 1314 is toward the back 122, and the extension direction of the second end a2 of the first cable 15 for electrical connection with the connector 14 is away from the back 122. In order to be able to electrically connect with the connector 14, the first cable 15 only needs to be bent once in the direction away from the back, and after bending, the angle δ at the bending point is large, the bending degree is small, and the bending is easier. In addition, the second cable 30 only needs to be bent once at the connection with the connector 14, which facilitates the installation of the second cable 30.

[0087] When α=90°, Figure 8 As shown, the first groove wall 1312 is perpendicular to the back side 122, and the axis of the mounting hole 1314 opened on the first groove wall 1312 is parallel to the back side 122. After one end of the connector 14 passes through the mounting hole 1314, the extension direction of the connector 14 is parallel to the back side 122. 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 groove wall 1312, at this time, when the first cable 15 is connected to the connector 14 and the preset port 123, the extension direction of the second end a2 of the first cable 15 is parallel to the back side 122. In other words, the first cable 15 can be connected to the connector 14 without bending. In addition, the angle θ of the second cable 30 after bending at the connection with the connector 14 is large, the bending degree is small, and the bending is easy, which is convenient for the installation of the second cable 30.

[0088] To sum up, 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 side 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 is convenient for 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 convenience of installation of the antenna structure and reducing the transmission loss in the first cable 15.

[0089] Further, continue as Figure 5A As shown, the groove has a second groove wall 1313, 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.

[0090] 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, and the second cable 30 (such as Figure 2When the connector (as shown) is inserted into the groove to connect with the connector, the operator has a small operating space and the connection operation is difficult.

[0091] In the antenna structure provided in the present application, the second angle β between the first groove wall 1312 and the second groove wall 1313 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, thereby improving the convenience of installation and maintenance of the antenna structure and the second cable.

[0092] When the antenna array assembly 12 (such as Figure 3C ) and the radio remote unit 40 (as shown Figure 2 When there are multiple groups of RF signals to be exchanged between the antenna structure 10 or multiple signal transmission paths are required, the connector 14 (such as Figure 3A At this time, when only the mounting holes 1314 are provided on the first slot wall 1312, due to the size of the mounting seat body 131, the first slot wall 1312 may not be provided with enough mounting holes 1314 for multiple connectors 14 to pass through.

[0093] In order to solve the above problems, Fig. 9 As shown, the second slot wall 1313 of the mounting seat body 131 may be provided with a mounting hole 1314. One end of different connectors 14 close to the antenna array assembly 12 may pass through the mounting hole 1314 on the first slot wall 1312 or the second slot wall 1313 to connect with the first cable 15, ensuring that multiple connectors 14 can be connected to the above-mentioned preset port 123 (such as Figure 3C ) electrical connections.

[0094] Alternatively, in some other embodiments of the present application, the mounting seat body 131 may be as follows: Fig.10 As shown, a mounting hole 1314 is provided on the bottom of the groove, and the bottom of the groove is parallel to the back surface. Fig.11 As shown, the connector 14 (such as Figure 3C ) is perpendicular to the back surface 122 (as shown Figure 3C As shown in the figure, the connector 14 can be accommodated in the groove when the groove has a small depth, 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. Figure 4 As shown, when the mounting seat 13 is located directly above the preset port 123 , the connector 14 is perpendicular to the back surface 122 , so that the connector 14 can be directly electrically connected to the preset port 123 .

[0095] On this basis, continue Fig.10As shown, the groove has a plurality of groove walls, and the groove walls and the bottom have a third angle γ; wherein, 80°≤γ<100°; illustratively, 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 side 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 side 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 antenna array assembly 12 (such as Figure 3C The transmission requirements of the radio frequency signal (as shown).

[0096] Furthermore, in order to enable the above-mentioned mounting seat body 131 to accommodate more connectors 14 and ensure that one end of the connector 14 can pass through the mounting hole 1314 and be electrically connected to the preset port 123, as shown in FIG. Fig.12 As shown, a mounting hole 1314 may be provided on the groove wall of the groove. Figure 3A The connectors 14 shown in the figure can be installed on the bottom or the groove wall respectively, so that the groove can accommodate more connectors 14.

[0097] For the sake of convenience, the following examples are all based on the mounting seat body 131 of the mounting seat 13. Figure 5A As shown, the second accommodation cavity 1311 is described as a groove as an example.

[0098] Continue as Figure 5A As shown, the mounting seat 13 also includes a flange 133, which is fixedly arranged at the opening end of the groove. At this time, the flange 133 is located around the opening end of the groove and will not block the opening of the groove, ensuring that the connector 14 (such as Figure 3A as shown) and external cables (as Figure 2 In addition, the flange 133 and the antenna cover 11 (as shown) have a connection space. Figure 3A For example, a hole may be drilled on the flange 133, and the flange 133 and the radome 11 may be relatively fixed by a connecting piece. Alternatively, glue may be applied on the flange 133 to bond and fix the flange 133 and the radome 11. In any case, 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, so as to ensure that the mounting base 13 and the radome 11 are connected and installed.

[0099] To ensure the structural stability of the mount, continue as Figure 5AAs shown, the mounting seat 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 is connected to the first groove wall 1312, and the reinforcing rib 134 is connected to the second groove wall 1313. The reinforcing rib 134 improves the connection rigidity between the first groove wall 1312 and the second groove wall 1313, thereby achieving the purpose of improving the structural stability of the mounting seat 13.

[0100] In addition, if Fig.13 As shown, 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 arranged 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 second accommodating cavity 1311 (such as Figure 3B ) in the connector 14 (as shown) Figure 3A ) is closer to the inner wall of the antenna cover 11, so that the connector 14 is connected to the second cable 30 (as shown in FIG. Figure 2 as shown) connection.

[0101] Further, continue as Fig.13 As shown, the mounting bracket 132 may have an assembly space 1321 for accommodating the mounting seat body 131. The assembly space 1321 is a space surrounded by the frame 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 deforming due to force during the assembly process of the antenna structure 10, thereby affecting the connector 14 (such as Figure 3A ) and the mounting base body 131, thereby affecting the connection stability between the connector 14 and the preset port 123 (as shown in FIG. Figure 3C as shown) or the second cable 30 (as shown Figure 2 The connection effect shown).

[0102] In addition, in the above-mentioned embodiments, Fig. 16BThe mounting bracket 132 shown can be fixedly connected to the reflector 125, so that the mounting seat 13 is relatively fixed to the reflector 125 of the antenna array assembly 12 in the first accommodating cavity 111, so that when the antenna cover 11 is installed, the antenna array assembly 12 and the mounting seat 13 will not produce relative displacement. For example, a bracket hole (not shown in the figure) is provided on the mounting bracket 132, and a threaded hole (not shown in the figure) is provided on the reflector 125. The mounting bracket 132 and the reflector 125 are screwed through the bracket hole and connected with the threaded hole by screws (not shown in the figure), and finally the mounting bracket 132 and the reflector 125 are fixedly connected.

[0103] On this basis, if Fig.14 As shown, the antenna cover 11 may be provided with a first connection hole 112. The first connection hole 112 and the second accommodation cavity 1311 (as shown in FIG. Figure 3A For connecting to the radio remote unit 40 (as shown in Figure 2 as shown) and connector 14 (as Figure 3A A second cable (as shown) Figure 3B ) can pass through the first connecting hole 112 and extend into the second accommodating cavity 1311 (as shown Figure 3A As shown), it is then 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, thereby improving the convenience of installation and maintenance of the antenna structure.

[0104] In addition, if Fig.15 As shown, the inner wall of the radome 11 located on the side of the mounting base 13 away from the back is the first inner wall 113. The distance between the end of the connector 14 away from the antenna array assembly 12 and the first inner wall 113 of the radome 11 is a first distance h1. The mounting base 13 is away from the back 122 (such as Figure 3C The distance between the end face of the antenna 10 and the first inner wall 113 is a second distance h2. And h1 is greater than or equal to h2. That is to say, after the connector 14 is installed in the second accommodating cavity 1311 of the mounting seat body 131, the connector 14 never protrudes from the end face of the mounting seat 13. During the assembly process of the antenna structure 10, the mounting seat 13 prevents the connector 14 from directly contacting the antenna cover 11, thereby avoiding friction between the connector 14 and the inner wall of the antenna cover 11. Thereby, the purpose of avoiding passive intermodulation caused by repeated friction of the antenna cover 11 on the connector 14 during the assembly process of the antenna cover 11 is achieved.

[0105] In any of the above embodiments, if Fig.15 The connector 14 shown is connected to the mounting seat body 131 in the mounting hole 1314 (as shown in FIG. Figure 5A Ensure that the groove is sealed with the first accommodating cavity 111 (as shown) of the antenna cover 11 at the mounting hole 1314. Figure 3BAs shown in the figure, the antenna is relatively sealed to prevent the moist air in the groove from entering the first accommodating cavity 111 and affecting the performance of the antenna structure.

[0106] 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.

Figure 2 As shown in the figure, the second cable 30 can be electrically connected to the connector 14 after passing through the second connection hole 1611 and the first connection hole 112 in sequence, so as to achieve the purpose of improving the installation convenience of the second cable 30.

[0109] Continue as Fig. 16C As shown, the waterproof member 16 may include a boss 162. The boss 162 may be disposed on one side of the waterproof member body 161 close to the mounting seat 13. In addition, one end of the boss 162 extends into the first connection hole 112 and abuts against the mounting seat 13. In this way, the boss 162 can shield the connection between the mounting seat 13 and the antenna cover 11, thereby improving the waterproof performance of the connection.

[0110] On this basis, if Fig. 16C The antenna structure 10 shown may also include a first sealing member 101, which is disposed between the waterproof member 16 and the radome 11 to ensure the sealing between the waterproof member 16 and the radome 11, and prevent humid air or rainwater from entering the first accommodating cavity 111 (such as the connection between the waterproof member 16 and the radome 11 and the connection between the radome 11 and the mounting seat 13) in sequence. Figure 3B For example, the first sealing member 101 may be a waterproof rubber strip or a sealing ring.

[0111] In addition, if Fig.16AThe antenna structure 10 shown in the figure further includes a second sealing member 102, which is disposed between the mounting seat 13 and the radome 11 to ensure the sealing between the mounting seat 13 and the radome 11, and to prevent humid air or rain from entering the first accommodating cavity 111 (such as Figure 3B For example, the second sealing member 102 may be a waterproof adhesive strip or a sealing ring.

Fig. 16C As shown), the sealing performance of the connection between the mounting base 13 and the antenna cover 11 is improved.
