[0002] This application claims priority to Chinese Patent Application No. 202411135934.6, filed on August 16, 2024, entitled "An Antenna, Communication Device and Communication System", the entire contents of which are incorporated herein by reference. Technical Field

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

[0004] As network demands become increasingly sophisticated, customized designs are needed based on the surrounding environment. For example, base station deployment in urban areas requires more precise planning than simple coverage. Wireless communication uses high-frequency data transmission, and obstacles can significantly impact communication, necessitating adjustments to the antenna's radiated beam direction. Currently, base station antennas are typically fixed to the base station's mast using adjustment brackets, and the antenna beam direction is adjusted manually. This manual adjustment method not only increases the workload for workers but also poses higher safety risks, is inefficient, and inconvenient. Summary of the Invention

[0005] This application provides an antenna, a communication device, and a communication system. It enables adjustment of the antenna beam angle and improves the service life and reliability of the adjustment device.

[0006] In a first aspect, the application provides an antenna, which comprises a radome, a reflector plate and an adjusting device. The reflector plate and the adjusting device are arranged in the radome, so that the radome can effectively protect the adjusting device. Dust, water vapor and other impurities cannot harm the adjusting device, thereby improving the reliability and stability of the adjusting device. The reflector plate is provided with an array of radiation units, which comprises a plurality of radiation dipoles. The radiation dipoles can effectively emit electromagnetic waves outward or receive electromagnetic waves from the outside, thereby realizing the communication function of the antenna. The adjusting device comprises a driving mechanism and a transmission mechanism. The driving mechanism is the power source of the adjusting device, and the transmission mechanism is connected between the driving mechanism and the reflector plate, so as to transmit the power generated by the driving mechanism to the reflector plate. Specifically, the driving mechanism is fixedly installed relative to the radome. The driving mechanism drives the reflector plate to rotate around a first direction through the transmission mechanism, and drives the reflector plate to rotate around a second direction. The first direction and the second direction are perpendicular, and the first direction and the second direction are respectively parallel to the reflector plate. Therefore, the adjusting device adjusts the reflector plate to rotate around the first direction relative to the radome, and the array of radiation units arranged on the reflector plate rotates along the pitch direction, so as to realize the adjustment of the pitch angle of the radiation beam. In addition, the adjusting device adjusts the reflector plate to rotate around the second direction relative to the radome, and the array of radiation units arranged on the reflector plate rotates along the horizontal direction, so as to realize the adjustment of the horizontal angle of the radiation beam of the array of radiation units.

[0007] The antenna of the application adjusts the horizontal angle and the pitch angle of the beam of the antenna by using the adjusting device, without the need for a person to climb the holding pole to adjust the direction of the antenna. This is conducive to simplifying the adjustment process of the beam direction of the antenna, and the operation is relatively simple and the adjustment efficiency is relatively high. In addition, the pitch angle and the horizontal angle of the antenna can be adjusted, which is conducive to enriching the use scenarios of the antenna and improving the coverage adjustability of the antenna, thereby optimizing the network performance of the antenna. In addition, the radome can protect the adjusting device, thereby improving the reliability and service life of the adjusting device.

[0008] In one embodiment, the reflector plate of the antenna comprises a first reflector plate and a second reflector plate, and the adjusting device comprises a first adjusting device and a second adjusting device. The first adjusting device is connected to the first reflector plate, and the second adjusting device is connected to the second reflector plate, so as to respectively adjust the beam direction of the first reflector plate and the second reflector plate. Specifically, the first adjusting device comprises a first driving mechanism and a first transmission mechanism, the first transmission mechanism is connected between the first driving mechanism and the first reflector plate, the first driving mechanism drives the first reflector plate to rotate around a first direction through the first transmission mechanism, and drives the first reflector plate to rotate around a second direction. The second adjusting device comprises a second driving mechanism and a second transmission mechanism, the second transmission mechanism is connected between the second driving mechanism and the second reflector plate, the second driving mechanism drives the second reflector plate to rotate around the first direction through the second transmission mechanism, and drives the second reflector plate to rotate around the second direction. The first reflector plate and the second reflector plate are adjusted by different driving devices, so that the two reflector plates can respectively adjust the beam direction according to actual needs, so as to enrich the use scenarios of the antenna.

[0009] In a further technical solution, the first reflector plate is provided with a first array of radiating elements, and the second reflector plate is provided with a second array of radiating elements. The working frequency band of the first array of radiating elements is at least partially different from the working frequency band of the second array of radiating elements. The beam directions of the arrays of radiating elements with different working frequency bands are likely to be different. This solution can adjust the beam directions of different arrays of radiating elements to improve the control accuracy of the antenna radiation direction.

[0010] In this application, the first reflector plate and the second reflector plate of the antenna can be arranged in a first direction or in a second direction. The orientation of the first reflector plate and the second reflector plate can be adjusted by using the technical solution of this application.

[0011] In a specific implementation, when the first reflector plate and the second reflector plate are arranged in the second direction, the antenna further comprises a first auxiliary frame, the first auxiliary frame is rotatably mounted on the radome around the second direction, the first reflector plate is rotatably mounted on the first auxiliary frame around the first direction, and the second reflector plate is rotatably mounted on the first auxiliary frame around the first direction.

[0012] In another specific implementation, the first reflector plate and the second reflector plate are arranged in the first direction, the antenna further comprises a first auxiliary frame, the first auxiliary frame is rotatably mounted on the radome around the first direction, the first reflector plate is rotatably mounted on the first auxiliary frame around the second direction, and the second reflector plate is rotatably mounted on the first auxiliary frame around the second direction.

[0013] In a further technical solution, the antenna further comprises a third array of radiating elements, a first part of the third array of radiating elements is arranged on the first reflector plate, and a second part of the third array of radiating elements is arranged on the second reflector plate. That is, the radiating elements of the third array of radiating elements are arranged on different reflector plates. The operating frequency band of the third array of radiating elements is different from at least part of the operating frequency band of the first array of radiating elements and the operating frequency band of the second array of radiating elements. The antenna in this solution supports signal transmission of different frequency bands. The first part of the radiating elements is connected to a first phase shifter, the second part of the radiating elements is connected to a second phase shifter, and the first phase shifter and the second phase shifter are respectively connected to a third phase shifter. The radiating elements on different reflector plates need to work cooperatively, so the combination of the first phase shifter, the second phase shifter and the third phase shifter is used to adjust and compensate the phase and amplitude of different radiating elements, so that the signal phases of the third array of radiating elements are aligned, thereby improving the radiation efficiency of the antenna.

[0014] In a technical solution, the antenna further comprises an auxiliary fixing structure, the auxiliary fixing structure is rotatably mounted on the radome around the second direction, and the reflector plate is rotatably mounted on the auxiliary fixing structure around the first direction.

[0015] Since the adjusting device needs to adjust the orientation of the reflector plate from two directions, the driving mechanism includes a first direction driving mechanism and a second direction driving mechanism, and the transmission mechanism includes a first direction transmission mechanism and a second direction transmission mechanism. The first direction transmission mechanism is connected between the first direction driving mechanism and the reflector plate to drive the reflector plate to rotate around the first direction. The first connection point of the first direction transmission mechanism and the reflector plate is located on the first symmetry axis of the reflector plate, and the first symmetry axis extends along the first direction, thereby reducing the space required for the reflector plate to rotate around the first direction. The second direction transmission mechanism is connected between the second direction driving mechanism and the reflector plate to drive the reflector plate to rotate around the second direction. The second connection point of the second direction transmission mechanism and the reflector plate is located on the second symmetry axis of the reflector plate, and the second symmetry axis extends along the second direction, thereby reducing the space required for the reflector plate to rotate around the second direction.

[0016] In some technical solutions, the first direction transmission mechanism and the second direction transmission mechanism are connected to the same point of the reflector plate, specifically to a third connection point, and the third connection point is located at the intersection of the first symmetry axis and the second symmetry axis of the reflector plate. No matter the reflector plate rotates around the first direction or the second direction, only a small amount of space is required. In addition, this solution also requires a small space for the first direction transmission mechanism and the second direction transmission mechanism, which is beneficial to improving the integration of the antenna.

[0017] In a technical solution, the antenna further comprises an auxiliary fixing structure. The auxiliary fixing structure is fixed to the radome, the driving mechanism is fixedly installed on the auxiliary fixing structure, and the auxiliary fixing structure has a preset distance from the radome, so that a containing space is formed between the auxiliary fixing structure and the radome for arranging some accessories of the antenna. In addition, the shape, arrangement position, and strength of the auxiliary fixing structure can be flexibly designed according to actual requirements, so as to improve the layout rationality of the adjusting device.

[0018] Specifically, the driving mechanism in the adjusting device comprises a motor, the transmission mechanism comprises a gear set or a worm gear, and the motor is self-locked to fix the reflecting plate at a set angle. The motor can be self-locked, so that the reflecting plate can be fixed at a set angle, and signals can be radiated at the set angle.

[0019] The antenna further comprises a controller unit electrically connected with the driving mechanism, and the controller unit is configured to control the driving mechanism to start or stop. In this technical solution, the controller unit can be used to control the movement of the driving mechanism, so that the angle of the antenna radiation beam can be remotely adjusted, and the adjustment mode of the beam direction of the antenna is simplified.

[0020] In a second aspect, the application further provides a communication device comprising a guyed tower, an adjusting support, and the antenna. The antenna can be fixedly installed on the guyed tower through the adjusting support. The spatial posture of the radome can be adjusted through the adjusting support.

[0021] In an example, the communication device can further comprise a baseband processing unit. The baseband processing unit is connected with a feed network in the antenna. The antenna can be an active antenna or a passive antenna. For example, when the antenna is an active antenna, a radio frequency processing unit can be included in the antenna, and the baseband processing unit can be connected with the feed network through the radio frequency processing unit. Alternatively, when the antenna is a passive antenna, the baseband processing unit can be directly connected with the feed network.

[0022] The radio frequency processing unit can be used to perform frequency selection, amplification, and down-conversion processing on signals received by a dipole in the antenna. Alternatively, the radio frequency processing unit can be used to send radio frequency signals to the antenna, so as to realize signal transmission and reception of the antenna. By applying the above-mentioned antenna, the pitch angle and the horizontal angle of the antenna beam can be adjusted, and the service life and reliability of the adjusting device can be improved, so as to effectively optimize the network performance of the communication device.

[0023] The baseband processing unit is connected with the radio frequency processing unit. The radio frequency processing unit can be used to perform frequency selection, amplification, and down-conversion processing on signals received by the antenna, and convert the signals into intermediate frequency signals or baseband signals and send them to the baseband processing unit. Alternatively, the radio frequency processing unit can be used to convert intermediate frequency signals output by the baseband processing unit into wireless signals through up-conversion and amplification processing, and send the wireless signals through the antenna.

[0024] In a third aspect, the present application provides a communication system, comprising the core network device and the communication device as described above, and the communication device is in communication connection with the core network device, so as to realize the wireless communication function. In the communication system provided by the present application, by being equipped with the communication device as described above, the signal transceiving performance of the communication system can be effectively improved and better adaptive flexibility can be achieved.

[0049] The antenna provided by the embodiments of the application can be applied in a communication device such as a base station or a radar to implement a wireless communication function.

[0050] FIG. 1 is a schematic diagram of an application scenario of a communication system in an embodiment of the present application. As shown in FIG. 1, the application scenario can include a communication device and a terminal. Wireless communication can be implemented between the communication device and the terminal. The communication device can be located in a base station subsystem (BBS), a universal terrestrial radio access network (UTRAN), or an evolved universal terrestrial radio access network (E-UTRAN), and is used for cell coverage of wireless signals to implement communication between a terminal device and a wireless network. Specifically, the communication device can be a base transceiver station (BTS) in a global system for mobile communication (GSM) or a code division multiple access (CDMA) system, a node B (NodeB, NB) in a wideband code division multiple access (WCDMA) system, an evolutional NodeB (eNB or eNodeB) in a long term evolution (LTE) system, a wireless controller in a cloud radio access network (CRAN) scenario, or the like.

[0052] Fig. 2 is a structural schematic diagram of a communication device according to an embodiment of the present application. As shown in Fig. 2, the communication device according to an embodiment of the present application can be understood as a base station, which includes a base station antenna feeder system. In actual application, the base station antenna feeder system mainly includes an antenna 01, a feeder 02 and a grounding device 03, etc. The antenna 01 is generally fixed on a holding pole 04, and the down-tilt angle of the antenna 01 can be adjusted by an antenna adjustment fixing frame 05, so as to adjust the signal coverage range of the antenna 01 to a certain extent.

[0053] In addition, the communication device can further include a radio frequency processing unit 06 and a baseband processing unit 20. For example, the radio frequency processing unit 06 can be used to perform frequency selection, amplification and down-conversion processing on the signal received by the antenna 01, and convert the signal into an intermediate frequency signal or a baseband signal and send the signal to the baseband processing unit 20, or the radio frequency processing unit 06 is used to convert the intermediate frequency signal sent by the baseband processing unit 20 into a wireless signal through up-conversion and amplification processing and send the signal out through the antenna 01. The baseband processing unit 20 can be connected to the feeder network of the antenna 01 through the radio frequency processing unit 06. In some embodiments, the radio frequency processing unit 06 can also be referred to as a radio frequency remote unit (RRU), and the baseband processing unit 20 can also be referred to as a baseband unit (BBU).

[0054] As shown in Fig. 2, in a possible embodiment, the radio frequency processing unit 06 can be integrally arranged with the antenna 01, and the baseband processing unit 20 is located at the far end of the antenna 01, and the radio frequency processing unit 06 and the baseband processing unit 20 can be connected through the feeder 02. In another embodiment, the radio frequency processing unit 06 and the baseband processing unit 20 can also be located at the far end of the antenna 01.

[0055] Fig. 3 is a structural schematic diagram of an antenna according to an embodiment of the present application. Please refer to Figs. 2 and 3, the antenna 01 applied in the communication device can further include a radome 011 and a reflector plate 012 and a feeder network 013 located in the radome 011, wherein the reflector plate 012 can also be referred to as a bottom plate. The main function of the feeder network 013 is to feed the signal to the vibrator 014 according to a certain amplitude and phase, or send the wireless signal received by the vibrator 014 to the baseband processing unit 20 of the base station according to a certain amplitude and phase. It can be understood that in specific implementation, the feeder network 013 can include at least one of a phase shifter, a combiner, a transmission or calibration network or a filter, etc. The composition components, types and functions that can be achieved by the feeder network 013 are not limited in the present application.

[0056] Of course, the above-mentioned antenna 01 can also be applied to various other types of communication devices, and the application scenarios of the antenna 01 are not limited in the present application.

[0057] It should be noted that in actual application, the holding pole 04, the antenna adjusting fixing frame 05 and the like can be provided by a venue provider. The antenna 01, the radio frequency processing unit 06, the baseband processing unit 20 and the like in the base station can be provided by a base station manufacturer. The base station in the embodiment of the present application can also not include the antenna adjusting fixing frame 05, as long as it includes a support capable of mounting the antenna to the holding pole, which can not have an adjusting function.

[0058] For the radome 011, in terms of electrical performance, the radome 011 has good electromagnetic wave penetration, so as not to affect the normal transmission and reception of electromagnetic waves between the oscillator 014 and the outside. In terms of mechanical performance, the radome 011 has good stress resistance and oxidation resistance and the like, so as to be able to withstand the erosion of the external harsh environment.

[0059] For the oscillator 014, which can also be called a radiator or a radiation unit, is a unit constituting the basic structure of the antenna, which can effectively emit or receive electromagnetic waves. In specific application, the oscillator 014 can be divided into single-stage and dual-polarization types. In specific configuration, the type of the oscillator 014 can be reasonably selected according to actual needs.

[0060] With the development of wireless communication technology, the industry has higher requirements for the signal coverage range of the antenna 01.

[0061] For example, FIG. 4 is a structural schematic diagram of a communication device radiator signal in the prior art, as shown in FIG. 4, the approximate beam coverage range of the wireless signal radiated by the antenna 01 is shown.

[0062] In summary, the beam radiated by the antenna 01 can effectively cover the signal on the ground area, so that the terminal device (such as a mobile phone) on the ground can communicate with the antenna 01.

[0063] In actual application, different ground areas have uneven population distribution. Therefore, the coverage demand for signals is different in different ground (or horizontal) areas. In the current antenna 01, the antenna 01 is generally fixed on the holding pole 04 of the base station through the adjusting support 05, which is difficult to adjust. In actual use, it is difficult to flexibly adjust the beam direction of the antenna 01 through the adjusting support 05, which is not conducive to fully utilizing the network performance of the antenna 01.

[0064] Therefore, the present application provides an antenna capable of flexibly adjusting the beam direction.

[0065] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0066] Fig. 5 is a schematic diagram of a front view of an antenna according to an embodiment of the present application, Fig. 6 is a schematic diagram of a side view of an antenna according to an embodiment of the present application, and Fig. 7 is a schematic diagram of a top view of an antenna according to an embodiment of the present application. As shown in Figs. 5-7, in an embodiment provided by the present application, the antenna 10 includes a radome 11, a reflector plate 12, and an adjusting device 13. The reflector plate 12 includes two opposite plate surfaces. One of the plate surfaces is provided with a radiating element array 14, which includes a plurality of radiating elements capable of effectively emitting electromagnetic waves or receiving electromagnetic waves from the outside. It should be noted that, in order to distinguish and describe the two plate surfaces of the reflector plate 12, in the following examples, the plate surface of the reflector plate 12 provided with the radiating element array 14 is referred to as a reflecting surface, and the other plate surface is referred to as a back surface.

[0067] As shown in Figs. 5-7, in an embodiment provided by the present application, the adjusting device 13 includes a driving mechanism 131 and a transmission mechanism 132. The driving mechanism 131 is a power source of the adjusting device 13. The transmission mechanism 132 is connected between the driving mechanism 131 and the reflector plate 12, and is configured to transmit power from the driving mechanism 131 to the reflector plate 12. The driving mechanism 131 drives the reflector plate 12 to rotate around a first direction X and a second direction Y through the transmission mechanism 132. The first direction X and the second direction Y are perpendicular to each other. The driving mechanism 131 is fixedly installed relative to the radome 11, thereby driving the reflector plate 12 to rotate around the first direction X and the second direction Y relative to the radome 11. The first direction X and the second direction Y are parallel to the reflector plate 12, respectively.

[0068] In the embodiment shown in the figures, the reflector plate 12 rotates around the first direction X relative to the radome 11, and the radiating element array 14 provided on the reflector plate 12 rotates along the elevation direction, which can be understood as adjustment of the elevation angle of the radiation beam of the radiating element array 14; the reflector plate 12 rotates around the second direction Y relative to the radome 11, and the radiating element array 14 provided on the reflector plate 12 rotates along the horizontal direction, which can be understood as adjustment of the horizontal angle of the radiation beam of the radiating element array 14 of the reflector plate 12. In other embodiments, the reflector plate 12 can also be caused to rotate around the first direction X relative to the radome 11, which can also be understood as adjustment of the horizontal angle of the radiation beam of the radiating element array 14; the reflector plate 12 can also be caused to rotate around the second direction Y relative to the radome 11, which can also be understood as adjustment of the elevation angle of the radiation beam of the radiating element array 14 of the reflector plate 12.

[0069] The antenna 10 in the embodiments of the present application can adjust the horizontal angle and the elevation angle of the antenna 10 by using the adjusting device 13, without manually climbing the holding pole to adjust the antenna adjustment fixing support of the antenna 10 to adjust the orientation of the reflector plate 12 of the antenna 10. This is advantageous to simplify the adjustment process of the beam direction of the antenna 10, and the operation is relatively simple and the adjustment efficiency is relatively high. Moreover, the elevation angle and the horizontal angle of the antenna 10 can be adjusted, which is advantageous to enrich the use scenarios of the antenna 10 and improve the coverage adjustability of the antenna 10, thereby optimizing the network performance of the antenna 10. In addition, the adjusting device 13 is located in the antenna cover 11, so that the antenna cover 11 can effectively protect the adjusting device 13. This can prevent impurities such as dust and water vapor from damaging the adjusting device 13, thereby improving the reliability and stability of the adjusting device 13.

[0070] In an embodiment, the antenna further comprises a controller unit electrically connected with the driving mechanism, and the controller unit is configured to control the driving mechanism to start or stop. In this technical solution, the controller unit can be used to control the movement of the driving mechanism, so that the angle of the antenna radiation beam can be remotely adjusted, and the adjustment mode of the beam direction of the antenna is simplified.

[0071] For example, the controller unit can be connected with an external module in communication through an AISG interface, so as to remotely control the movement of the driving mechanism.

In this scheme, the reflector plate 12 rotates around the first symmetry axis M, and the space required in the rotation process is relatively small, which is advantageous to reduce the size of the antenna cover 11.
