[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on August 2, 2023, with application number 202310970738.X and application name “Directing plate structure, base station antenna and base station”, the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of antennas, and in particular to a director structure, a base station antenna, and a base station. Background Art

[0004] With the rapid development of wireless communication technology, the demand for communication system capacity is increasing. Broadband and multi-frequency antennas are widely used in base station antennas. Adding a director to a low-frequency antenna can expand its bandwidth, achieving broadband antennas. However, in a multi-frequency antenna system, the introduction of a director can significantly interfere with the radiation performance of the high-frequency antenna in the multi-frequency antenna.

[0005] Summary of the Invention

[0006] The present application provides a director plate structure, a base station antenna, and a base station to reduce the interference of the director plate on the radiation performance of the high-frequency antenna.

[0007] In the first aspect, the present application provides a guide plate structure that can be arranged above an antenna structure. The guide plate structure may include a first guide plate and at least one second guide plate, the first guide plate may have a through hole, the at least one second guide plate may be arranged in the through hole, and the first end of the at least one second guide plate may be fixedly connected to the first guide plate. The outer edge of the first guide plate may be provided with at least one first branch, the at least one first branch may extend along the outer edge contour of the first guide plate, and the at least one first branch may be fixedly connected to the first guide plate. The first end of the second guide plate may have an opening, the opening may extend along the extension direction of the second guide plate, a second branch may be provided in the opening, and the second branch may extend along the extension direction of the second guide plate.

[0008] In the technical solution provided in the present application, the high-frequency antenna in the multi-frequency antenna can generate an induced current I1 on the first branch node, and the direction of the induced current I1 is opposite to the direction of the induced current I2 generated by the high-frequency antenna on the first director plate. The induced current I1 and the induced current I2 can cancel each other out, which is equivalent to not generating an induced current on the first director plate. Therefore, the setting of the first branch node can achieve wave transmission of the first director plate. The high-frequency antenna in the multi-frequency antenna can generate an induced current J1 on the second branch node, and the direction of the induced current J1 is opposite to the direction of the induced current J2 generated by the high-frequency antenna on the second director plate. The induced current J1 and the induced current J2 can cancel each other out, which is equivalent to not generating an induced current on the second director plate. Therefore, the setting of the second branch node can achieve wave transmission of the second director plate. Therefore, the director plate structure has a wave transmission characteristic, which can not only broaden the bandwidth of the low-frequency antenna in the multi-frequency antenna, but also achieve wave transmission for the high-frequency antenna in the multi-frequency antenna, and has less interference with the radiation performance of the high-frequency antenna. At the same time, the director plate structure is arranged above the antenna structure. For example, the director plate structure is arranged above the low-frequency antenna in the multi-frequency antenna. There is no direct electrical connection between the director plate structure and the low-frequency antenna. The setting of the first branch and the second branch has little effect on the impedance matching between the director plate structure and the low-frequency antenna, and has little effect on the radiation performance of the low-frequency antenna.

[0009] In one specific embodiment, the director structure may include four second director plates, which may be arranged axially around the through hole. Two of the second director plates may be arranged along a first direction, and the other two may be arranged along a second direction. The first and second directions may be perpendicular. The four second director plates may correspond to the four oscillators of a dipole-type low-frequency antenna, thereby expanding the bandwidth of the low-frequency antenna.

[0010] When the second branch is specifically set up, the second branch may include a first section, a second section and a third section. The first section may extend along the extension direction of the second guide plate, the second section may be set parallel to the first section, and the first section and the second section may be fixedly connected through the third section; the third section may be fixedly connected to the second guide plate to realize the connection between the second branch and the second guide plate.

[0011] In one specific embodiment, one end of the third segment can be fixedly connected to one end of the first segment, and the other end of the third segment can be fixedly connected to one end of the second segment. The first segment and the second segment can be located on the same side of the third segment. The third segment, the first segment, and the second segment can form a second branch of a U-shaped structure. The second director with an opening can also be considered a U-shaped structure. The induced current generated by the high-frequency antenna on the second branch and the induced current generated by the high-frequency antenna on the second director have similar paths and opposite directions, and can cancel each other out, thereby achieving wave transmission through the second director.

[0012] In an optional solution, the first guide plate may be circular. In another optional solution, the first guide plate may be square.

[0013] In a specific embodiment, the first branch may be fixedly connected to the first guide plate via a first connecting member, thereby achieving a fixed connection between the first branch and the first guide plate.

[0014] In one specific embodiment, one end of the first connector can be fixedly connected to one end of the first branch, and the other end of the first connector can be fixedly connected to the first director. In this way, the induced current generated by the high-frequency antenna on the first branch and the induced current generated by the high-frequency antenna on the first director have similar paths but opposite directions, and can cancel each other out, thereby achieving wave transmission through the first director.

[0015] In a specific embodiment, the third section may be fixedly connected to the second guide plate via a second connecting member, thereby achieving a fixed connection between the second branch and the second guide plate.

[0016] In a specific embodiment, the second connecting member, the first section, and the second section may be located on the same side of the third section, so as to effectively utilize the layout space within the opening range of the second guide plate.

[0017] In a second aspect, the present application provides a base station antenna, which may include an antenna structure and a director structure as described in any of the possible implementations of the first aspect, the director structure being disposed above the antenna structure. The director structure can both broaden the bandwidth of the low-frequency antenna in a multi-frequency antenna and provide wave transmission for the high-frequency antenna in the multi-frequency antenna, thereby minimizing interference with the radiation performance of the high-frequency antenna and achieving ideal base station antenna performance.

[0018] In a third aspect, the present application provides a base station, which may include the base station antenna as described in the second aspect. The base station has reliable performance and high stability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as being limited to the embodiments set forth herein. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted. The words expressing position and direction described in the embodiments of the present application are all explained with reference to the accompanying drawings as examples, but changes may be made as needed, and the changes made are all included in the scope of protection of the present application. The drawings in the embodiments of the present application are only used to illustrate the relative position relationship and do not represent the true proportion.

[0030] The following description sets forth specific details to facilitate understanding of the present application. However, the embodiments of the present application can be implemented in a variety of other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotations of the embodiments of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0031] FIG1 exemplarily shows a schematic diagram of a system architecture applicable to an embodiment of the present application. As shown in FIG1 , the system architecture may include a wireless access network device and a terminal, such as but not limited to the base station shown in FIG1 . Wireless communication can be achieved between the wireless access device and the terminal. The wireless access network device may be located in a base station subsystem (BSS), a terrestrial radio access network (UMTS terrestrial radio access network, UTRAN) or an evolved universal terrestrial radio access (E-UTRAN), and is used to provide cell coverage of wireless signals to achieve connection between the terminal device and the radio frequency end of the wireless network. Specifically, the base station can be a base station (base transceiver station, BTS) in a GSM or CDMA system, a base station (NodeB, NB) in a WCDMA system, an evolved base station (evolutional NodeB, eNB or eNodeB) in an LTE system, or a wireless controller in a cloud radio access network (CRAN) scenario, or the base station can also be a relay station, an access point, a vehicle-mounted device, a wearable device, a base station in a 5G network, or a base station in a future evolved PLMN network, for example, a new wireless base station, which is not limited in the embodiments of the present application.

[0032] Figure 2 shows a schematic diagram of the antenna feed system of a base station according to one embodiment of the above figure. The base station antenna feed system typically includes an antenna 10, a mast 20, and an antenna adjustment bracket 30. The base station antenna 10 includes a radome 40. This radome 40 has excellent electrical electromagnetic wave penetration characteristics and mechanical properties that can withstand harsh external environments, thereby protecting the antenna system from external environmental influences. The radome 40 can be mounted on the mast 20 or tower via the antenna adjustment bracket 30 to facilitate signal reception or transmission by the antenna 10.

[0033] In addition, the base station may further include a radio frequency processing unit 50 and a signal processing unit 60. For example, the radio frequency processing unit 50 may be configured to perform frequency selection, amplification, and down-conversion processing on the signal received by the antenna 10, and convert the signal into an intermediate frequency signal or a baseband signal, which is then transmitted to the signal processing unit 60. Alternatively, the radio frequency processing unit 50 may be configured to convert the intermediate frequency signal from the signal processing unit 60 into an electromagnetic wave through the antenna 10 after up-conversion and amplification, and then transmit the electromagnetic wave. The signal processing unit 60 may be connected to the feed structure of the antenna 10 via the radio frequency processing unit 50, and may be configured to process the intermediate frequency signal or baseband signal transmitted by the radio frequency processing unit 50.

[0034] In one possible embodiment, as shown in FIG2 , the RF processing unit 50 may be integrated with the antenna 10, and the signal processing unit 60 may be located at the distal end of the antenna 10. In other embodiments, the RF processing unit 50 and the signal processing unit 60 may be located at the distal end of the antenna 10. The RF processing unit 50 and the signal processing unit 60 may be connected via a cable 70.

[0035] More specifically, Figures 2 and 3 may be referenced together. Figure 3 is a schematic structural diagram of a base station antenna according to a possible embodiment of the present application. As shown in Figure 3, the base station antenna 10 may include a radiating element 11 and a reflector 12. The radiating element 11, which may also be referred to as an antenna element or vibrator, is a unit that constitutes the basic structure of the antenna array and can effectively radiate or receive antenna signals. In antenna 10, the frequencies of different radiating elements 11 may be the same or different. The reflector 12, which may also be referred to as a base plate, antenna panel, or metal reflective surface, can reflect and focus antenna signals at a receiving point. The radiating element 11 is typically placed on one side of the reflector 12. This not only significantly enhances the antenna 10's signal reception or transmission capabilities, but also blocks and shields interference from other radio waves originating from the back side of the reflector 12 (the back side of the reflector 12 in this application refers to the side of the reflector 12 opposite to the side where the radiating element 11 is located).

[0036] In the base station's antenna 10, the radiating element 11 is connected to a feed network 80. The feed network 80 typically consists of a controlled impedance transmission line. It can feed signals to the radiating element 11 at a specific amplitude and phase, or transmit received signals to the base station's signal processing unit 60 at a specific amplitude and phase. Furthermore, the feed network 80 can achieve different radiation beam directions through a transmission component 81, or connect to a calibration network 82 to obtain calibration signals required by the system. The feed network 80 may include a phase shifter 83 to change the maximum direction of antenna signal radiation. The feed network 80 may also include modules to extend performance, such as a combiner 84 (which can be used to combine signals of different frequencies into one channel for transmission through the antenna 10; or, in reverse, to divide the signals received by the antenna 10 into multiple channels based on different frequencies and transmit them to the signal processing unit 60 for processing), a filter 85 (which can be used to filter out interference signals), and other modules.

[0037] The director structure provided in the embodiments of the present application can be adapted for base station antenna 10. Multi-band antennas are widely used in base station antennas. Multi-band antennas typically include low-frequency antennas and high-frequency antennas. Adding a director to the low-frequency antenna in a multi-band antenna can extend the bandwidth of the low-frequency antenna, achieving a broadband antenna. However, the introduction of the director can significantly interfere with the radiation performance of the high-frequency antenna in the multi-band antenna.

[0038] Based on this, the present invention provides a director structure to reduce the interference of the director on the radiation performance of the high-frequency antenna and ensure the radiation performance of the high-frequency antenna. The following describes the director structure in detail.

[0039] Referring to Figure 4, Figure 4 shows a possible architectural schematic diagram of the director structure provided by an embodiment of the present application. As shown in Figure 4, the director structure 100 can be arranged above the antenna structure. For example, the director structure 100 can be arranged above the low-frequency antenna 200 in the multi-frequency antenna. The above mentioned here is based on the orientation in Figure 4. The above of the low-frequency antenna 200 can correspond to the end of the low-frequency antenna 200 away from the reflector 12. The director structure 100 can be fixed above the low-frequency antenna 200 by a fixing member such as an insulating bracket. There is no direct electrical connection between the director structure 100 and the low-frequency antenna 200, and there is no direct electrical connection between the director structure 100 and the high-frequency antenna 300.

[0040] Referring to Figure 5 , a schematic diagram of a guide plate structure according to a possible embodiment of the present application is shown. As shown in Figure 5 , the guide plate structure may include a first guide plate 110 and at least one second guide plate 120. The first guide plate 110 may have a through hole 111. The at least one second guide plate 120 may be disposed within the through hole 111 of the first guide plate 110. Specifically, the first end of the at least one second guide plate 120 may be fixedly connected to the first guide plate 110, while the second end may be free.

[0041] In a specific implementation, the outer edge of the first guide plate 110 may be provided with at least one first branch 130, which may extend along the outer edge contour of the first guide plate 110 and may be fixedly connected to the first guide plate 110. The first end of the second guide plate 120 may have an opening 121, which may extend along the extension direction of the second guide plate 120. The second branch 140 may be provided in the opening 121, which may extend along the extension direction of the second guide plate 120.

[0042] Referring to FIG6 , FIG6 shows a schematic diagram of the induced current direction of the guide plate structure provided by a possible embodiment of the present application. In combination with FIG5 and FIG6 , the guide plate structure provided by the embodiment of the present application, the high-frequency antenna in the multi-frequency antenna can generate an induced current I1 on the first branch 130. The direction of the induced current I1 is opposite to the direction of the induced current I2 generated by the high-frequency antenna on the first guide plate 110. The induced current I1 and the induced current I2 can offset each other, which is equivalent to not generating an induced current on the first guide plate 110. Therefore, the setting of the first branch 130 can achieve wave transmission of the first guide plate 110, and the high-frequency antenna in the multi-frequency antenna can generate an induced current I1 on the second branch 140. The induced current J1 is generated, and the direction of the induced current J1 is opposite to the direction of the induced current J2 generated by the high-frequency antenna on the second guide plate 120. The induced current J1 and the induced current J2 can cancel each other out, which is equivalent to not generating an induced current on the second guide plate 120. Therefore, the setting of the second branch 140 can achieve wave transmission of the second guide plate 120. As a result, the guide plate structure has a wave-transmitting characteristic, which can not only broaden the bandwidth of the low-frequency antenna in the multi-frequency antenna, but also achieve wave transmission for the high-frequency antenna in the multi-frequency antenna, and has less interference with the radiation performance of the high-frequency antenna. At the same time, there is no direct electrical connection between the guide plate structure and the low-frequency antenna. The setting of the first branch 130 and the second branch 140 has little effect on the impedance matching between the guide plate structure and the low-frequency antenna, and has little effect on the radiation performance of the low-frequency antenna.

[0043] As a possible embodiment, the guide plate structure may include four second guide plates 120, specifically, the four second guide plates 120 may be arranged axially around the through hole 111. Two of the four second guide plates 120 may be arranged along a first direction, and the other two second guide plates 120 may be arranged along a second direction, the first direction may be perpendicular to the second direction, and when the guide plate structure is actually installed, the four second guide plates 120 may correspond to the four oscillators (or radiating arms) of the dipole-type low-frequency antenna, respectively, so as to expand the bandwidth of the low-frequency antenna. During specific implementation, one end of each second guide plate 120 may be fixedly connected to the first guide plate 110, and the other end may be free. The other end of the second guide plate 120 may be a triangle, and the other ends of the four second guide plates 120 may be brought together, and a cross-shaped gap may be formed between the other ends of the four second guide plates 120.

[0044] In one possible implementation, the first branch 130 can be fixedly connected to the area between two adjacent second guide pieces 120 on the first guide piece 110. This area can be fixedly connected to two first branches 130. As shown in Figure 1, when the guide piece structure includes four second guide pieces 120, the outer edge of the first guide piece 110 can be fixedly connected to eight first branches 130 along the circumferential direction.

[0045] When connecting the first branch 130, the first branch 130 can be fixedly connected to the first guide plate 110 via the first connector 150. Specifically, one end of the first connector 150 can be fixedly connected to one end of the first branch 130, and the other end of the first connector 150 can be fixedly connected to the first guide plate 110, thereby achieving a fixed connection between the first branch 130 and the first guide plate 110. The first branch 130 and the first connector 150 can be welded to achieve a fixed connection, and the first connector 150 and the first guide plate 110 can also be welded to achieve a fixed connection; alternatively, the first branch 130, the first connector 150, and the first guide plate 110 can be integrally formed; alternatively, the first branch 130 and the first connector 150 can be integrally formed, and the first connector 150 and the first guide plate 110 can be welded; alternatively, the first connector 150 and the first guide plate 110 can be integrally formed, and the first branch 130 and the first connector 150 can be welded.

[0046] Referring to Figure 7, Figure 7 shows a schematic structural diagram of the second branch of the guide plate structure provided by a possible embodiment of the present application. In combination with Figures 5 and 7, in a possible specific implementation, the second branch 140 may include a first section 141, a second section 142, and a third section 143. The first section 141 may extend along the extension direction of the second guide plate 120, the second section 142 may be arranged parallel to the first section 141, and the first section 141 and the second section 142 may be fixedly connected by the third section 143. In a specific implementation, one end of the third section 143 may be fixedly connected to one end of the first section 141, and the other end of the third section 143 may be fixedly connected to one end of the second section 142. The first section 141 and the second section 142 may be located on the same side of the third section 143. The third section 143, the first section 141, and the second section 142 may form a U-shaped second branch 140 as a whole. The first end of the second guide plate 120 has an opening 121. The second guide plate 120 can also be considered a U-shaped structure. The induced current generated by the high-frequency antenna on the second branch 140 and the induced current generated by the high-frequency antenna on the second guide plate 120 have similar paths and opposite directions, and can cancel each other out, thereby achieving wave transmission through the second guide plate 120. Specifically, when connecting the second branch 140, the third section 143 can be fixedly connected to the second guide plate 120, thereby achieving a fixed connection between the second branch 140 and the second guide plate 120.

[0047] In actual configuration, the third section 143 can be fixedly connected to the second guide plate 120 via the second connector 160. Specifically, one end of the second connector 160 can be fixedly connected to the third section 143, and the other end of the second connector 160 can be fixedly connected to the second guide plate 120, thereby achieving a fixed connection between the third section 143 and the second guide plate 120, and thus achieving a fixed connection between the second branch 140 and the second guide plate 120. The third section 143 and the second connector 160 can be welded to achieve a fixed connection, and the second connector 160 and the second guide plate 120 can also be welded to achieve a fixed connection. Alternatively, the third section 143, the second connector 160, and the second guide plate 120 can be integrally formed. Alternatively, the third section 143 and the second connector 160 can be integrally formed, and the second connector 160 and the second guide plate 120 can be welded. Alternatively, the second connector 160 and the second guide plate 120 can be integrally formed, and the third section 143 and the second connector 160 can be welded. The second connecting member 160 , the first section 141 , and the second section 142 may be located on the same side of the third section 143 , so as to effectively utilize the layout space within the opening 121 of the second guide plate 120 .

[0048] In a possible specific implementation, the first guide plate 110 can be circular. The through hole 111 can be a circular hole. In this case, the first guide plate 110 is specifically annular, and the first direction and the second direction can be respectively the radial direction of the through hole 111, that is, the first direction can be the radial direction of the through hole 111, and the second direction can also be the radial direction of the through hole 111, and the first direction and the second direction are perpendicular to each other. In a specific implementation, the outer edge contour of the entire first guide plate 110 is circular, the outer edge contour of a part of the first guide plate 110 is arc-shaped, and the first branch 130 extends along the outer edge contour of the first guide plate 110. Therefore, the first branch 130 can be an arc-shaped structure, so that the induced current generated by the high-frequency antenna on the first branch 130 and the induced current generated by the high-frequency antenna on the first guide plate 110 have similar paths and opposite directions, and can offset each other, thereby achieving wave transmission of the first guide plate 110.

[0049] Referring to Figure 8, Figure 8 shows a schematic structural diagram of the guide plate structure provided by another possible embodiment of the present application. As shown in Figure 8, the first guide plate 110 can be square. The through hole 111 can be a square hole. In this case, the first guide plate 110 is specifically a square ring. The first direction and the second direction can be the directions of the diagonal lines of the through hole 111, respectively, and the first direction and the second direction are perpendicular to each other. In a specific implementation, the first branch 130 can be fixedly connected to the side length of the square first guide plate 110. The side length of the square first guide plate 110 is linear. The first branch 130 extends along the outer edge contour of the first guide plate 110. Thus, the first branch 130 can be a linear structure. The induced current generated by the high-frequency antenna on the first branch 130 and the induced current generated by the high-frequency antenna on the first guide plate 110 have similar paths and opposite directions, and can cancel each other out, thereby achieving wave transmission of the first guide plate 110.

[0050] Referring to Figure 9, Figure 9 shows a schematic structural diagram of a guide plate structure provided by another possible embodiment of the present application. As shown in Figure 9, the first guide plate 110 can be square. The through hole 111 can be a square hole. In this case, the first guide plate 110 is specifically a square ring. Different from the embodiment shown in Figure 8, the first direction and the second direction can be the directions of the side lengths of the through hole 111, respectively, and the first direction and the second direction are perpendicular. In specific implementation, similarly, the first branch 130 can be fixedly connected to the side length of the square first guide plate 110, and the side length of the square first guide plate 110 is linear. The first branch 130 extends along the outer edge contour of the first guide plate 110. Thus, the first branch 130 can be a linear structure. The induced current generated by the high-frequency antenna on the first branch 130 and the induced current generated by the high-frequency antenna on the first guide plate 110 have similar paths and opposite directions, and can cancel each other out, thereby achieving wave transmission of the first guide plate 110.

[0051] The above description introduces several implementations of the first guide plate 110 and the first branch 130. In addition to the implementations introduced in the above description, the first guide plate 110 and the first branch 130 may also have other implementations, several of which are listed below for introduction.

[0052] In one embodiment, the first guide plate 110 may be circular, and the through hole 111 may be a square hole. In this case, the first guide plate 110 is specifically annular with a circular outer edge and a square inner edge. The first direction and the second direction may be the directions of the diagonal of the through hole 111, respectively, and the first direction and the second direction are perpendicular to each other. In a specific implementation, the outer edge of the first guide plate 110 as a whole is circular, and the outer edge of a portion of the first guide plate 110 is arc-shaped. The first branch 130 extends along the outer edge of the first guide plate 110. Therefore, the first branch 130 may have an arc-shaped structure.

[0053] In another embodiment, the first guide plate 110 may be circular, and the through hole 111 may be a square hole. In this case, the first guide plate 110 is specifically annular with a circular outer edge and a square inner edge. Unlike the previous embodiment, the first direction and the second direction may be the directions of the side lengths of the through hole 111, respectively, and the first direction and the second direction are perpendicular to each other. In a specific implementation, the outer edge of the first guide plate 110 as a whole is circular, and the outer edge of a portion of the first guide plate 110 is arc-shaped. The first branch 130 extends along the outer edge of the first guide plate 110, thus the first branch 130 may have an arc-shaped structure.

[0054] In another embodiment, the first guide piece 110 can be square, and the through hole 111 can be a circular hole. In this case, the first guide piece 110 is specifically annular with a square outer edge and a circular inner edge. The first direction and the second direction can be radial directions of the through hole 111, that is, the first direction can be radial directions of the through hole 111, and the second direction can also be radial directions of the through hole 111, and the first direction and the second direction are perpendicular to each other. In a specific implementation, the first branch 130 can be fixedly connected to the side of the square first guide piece 110, and the side of the square first guide piece 110 is linear. The first branch 130 extends along the outer edge contour of the first guide piece 110, thus, the first branch 130 can be a linear structure.

[0055] It is understandable that the several possible implementations of the first guide plate 110 and the first branch 130 as a whole in the above examples can be selected according to specific needs in actual applications. Of course, other feasible implementations can also be adopted in actual applications and can be specifically set according to actual conditions.
