Description

Technical Field

[0001] 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

[0002] With the rapid development of wireless communication technology, the demand for communication system capacity is increasing. Broadband antennas and multi-frequency antennas are widely used in base station antennas. Loading a director on a low-frequency antenna can expand the bandwidth of the low-frequency antenna and realize a broadband antenna. However, in a multi-frequency antenna system, the introduction of a director will cause strong interference to the radiation performance of the high-frequency antenna in the multi-frequency antenna. Summary of the invention

[0003] 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.

[0004] 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 arranged in the opening, and the second branch may extend along the extension direction of the second guide plate.

[0005] 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, and 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, so that the setting of the first branch node can achieve wave transmission of the first director plate, and 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, and 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, so that the setting of the second branch node can achieve wave transmission of the second director plate, thus, 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.

[0006] In a specific implementation scheme, the director structure may include four second director plates, and the four second director plates may be arranged axially around the through hole, wherein two second director plates may be arranged along a first direction, and the other two second director plates may be arranged along a second direction, and the first direction and the second direction may be perpendicular to each other. The four second director plates may correspond to four oscillators of a dipole-type low-frequency antenna, respectively, to expand the bandwidth of the low-frequency antenna.

[0007] 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 and the first section may be set in parallel, and the first section and the second section may be fixedly connected via the third section; the third section and the second guide plate may be fixedly connected to realize the connection between the second branch and the second guide plate.

[0008] In a specific feasible implementation scheme, 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, and the first segment and the second segment can be located on the same side of the third segment. The third segment and the first segment and the second segment can form a second branch of a U-shaped structure as a whole, and the second director with an opening can also be regarded as 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 of the second director.

[0009] In an optional solution, the first guide piece may be circular. In another optional solution, the first guide piece may be square.

[0010] In a specific implementation manner, 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.

[0011] In a specific implementation scheme, 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 guide plate. 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 guide plate have similar paths and opposite directions, and can cancel each other, thereby achieving wave transmission of the first guide plate.

[0012] In a specific possible implementation manner, 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.

[0013] In a specific possible implementation manner, the second connecting member and 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.

[0014] In a second aspect, the present application provides a base station antenna, which may include an antenna structure and a director structure as in any of the possible implementation schemes in the first aspect, wherein the director structure is arranged above the antenna structure. The director structure 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, so that the performance of the base station antenna is relatively ideal.

[0015] In a third aspect, the present application provides a base station, which may include the base station antenna in the second aspect. The base station has reliable performance and high stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In order to make the purpose, technical scheme and advantages of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings. However, the example implementation can be implemented in various forms and should not be construed as being limited to the implementations 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 described 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 of the embodiments of the present application are only used to illustrate the relative position relationship and do not represent the true proportion.

[0035] The following description sets forth specific details to facilitate understanding of the present application, but the embodiments of the present application can be implemented in a variety of other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the embodiments of the present application. Therefore, the present application is not limited to the specific implementation methods disclosed below.

[0036] Figure 1 A schematic diagram of a system architecture applicable to the embodiment of the present application is shown as an example. Figure 1 As shown, the system architecture may include wireless access network equipment and terminals, such as but not limited to Figure 1 The base station shown. Wireless communication can be achieved between the wireless access device and the terminal. The wireless access network device can be located in a base station subsystem (BSS), a terrestrial radio access network (UMTS terrestrial radio access network, UTRAN) or an evolved terrestrial radio access network (evolved universal terrestrial radio access, E-UTRAN), and is used to provide cell coverage for wireless signals to achieve connection between the terminal device and the radio frequency end of the wireless network. 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 (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, etc., for example, a new wireless base station, which is not limited in the embodiments of the present application.

[0037] Figure 2The schematic diagram of the structure of the antenna feeding system of the base station in an embodiment as shown in the above figure is shown. The antenna feeding system of the base station can generally include structures such as an antenna 10, a pole 20, and an antenna adjustment bracket 30. Among them, the antenna 10 of the base station includes a radome 40, which has good electromagnetic wave penetration characteristics in electrical performance and can withstand the influence of external harsh environment in mechanical performance, thereby protecting the antenna system from the influence of the external environment. The radome 40 can be installed on the pole 20 or the tower through the antenna adjustment bracket 30 to facilitate the reception or transmission of the antenna 10 signal.

[0038] 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 used to perform frequency selection, amplification, and down-conversion processing on the signal received by the antenna 10, and convert it into an intermediate frequency signal or a baseband signal and send it to the signal processing unit 60, or the radio frequency processing unit 50 may be used to convert the intermediate frequency signal of the signal processing unit 60 into an electromagnetic wave through the antenna 10 after up-conversion and amplification processing and send it out. The signal processing unit 60 may be connected to the feeding structure of the antenna 10 through the radio frequency processing unit 50, and is used to process the intermediate frequency signal or baseband signal sent by the radio frequency processing unit 50.

[0039] In a possible embodiment, Figure 2 As shown, the RF processing unit 50 can be integrally provided with the antenna 10, and the signal processing unit 60 is located at the far end of the antenna 10. In some other embodiments, the RF processing unit 50 and the signal processing unit 60 can also be located at the far end of the antenna 10 at the same time. The RF processing unit 50 and the signal processing unit 60 can be connected via a cable 70.

[0040] More specifically, please refer to Figure 2 and Figure 3 , Figure 3 This is a schematic diagram of the structure of a base station antenna in a possible embodiment of the present application. Figure 3 As shown, the antenna 10 of the base station may include a radiation unit 11 and a reflector 12. The radiation unit 11 may also be referred to as an antenna vibrator, a vibrator, etc. The radiation unit 11 is a unit constituting the basic structure of the antenna array, which can effectively radiate or receive antenna signals. In the antenna 10, the frequencies of different radiation units 11 may be the same or different. The reflector 12 may also be referred to as a bottom plate, an antenna panel, or a metal reflective surface, etc. The reflector 12 may reflect the antenna signal and gather it at the receiving point. The radiation unit 11 is usually placed on one side of the reflector 12, which can not only greatly enhance the receiving or transmitting capability of the antenna 10 signal, but also block and shield the interference of other radio waves 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 radiation unit 11 is set) on the antenna signal reception.

[0041] In the antenna 10 of the base station, the radiation unit 11 is connected to the feed network 80. The feed network 80 is usually composed of a controlled impedance transmission line. The feed network 80 can feed the signal to the radiation unit 11 according to a certain amplitude and phase, or send the received signal to the signal processing unit 60 of the base station according to a certain amplitude and phase. In addition, the feed network 80 can realize different radiation beam pointing through the transmission component 81, or connect with the calibration network 82 to obtain the calibration signal 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 be provided with a combiner 84 (which can be used to combine signals of different frequencies into one path and transmit them through the antenna 10; or when used in reverse, it can be used to divide the signal received by the antenna 10 into multiple paths according to different frequencies and transmit them to the signal processing unit 60 for processing), a filter 85 (used to filter out interference signals) and other modules for expanding performance.

[0042] The director structure provided in the embodiment of the present application can be adapted to the antenna 10 of the base station antenna. Multi-frequency antennas are widely used in base station antennas. Multi-frequency antennas usually include low-frequency antennas and high-frequency antennas. Loading a director for a low-frequency antenna in a multi-frequency antenna can expand the bandwidth of the low-frequency antenna and realize a broadband antenna. However, the introduction of the director will cause strong interference to the radiation performance of the high-frequency antenna in the multi-frequency antenna.

[0043] Based on this, the embodiment of the present application provides a director plate structure to reduce the interference of the director plate on the radiation performance of the high-frequency antenna and ensure the radiation performance of the high-frequency antenna. The director plate structure is described in detail below.

[0044] Reference Figure 4 , Figure 4 A possible schematic diagram of the structure of the guide plate provided in the embodiment of the present application is shown. Figure 4 As shown, the guide plate structure 100 can be arranged above the antenna structure, for example, the guide plate structure 100 can be arranged above the low-frequency antenna 200 in the multi-frequency antenna. Figure 4 In the orientation of the low frequency antenna 200, the upper side of the low frequency antenna 200 may correspond to the end of the low frequency antenna 200 away from the reflector 12. The director structure 100 may be fixed on the upper side of 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.

[0045] Reference Figure 5 , Figure 5 FIG. 1 is a schematic diagram showing a structure of a guide plate structure provided by a possible embodiment of the present application. Figure 5As shown, 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 in the through hole 111 of the first guide plate 110. Specifically, a first end of the at least one second guide plate 120 may be fixedly connected to the first guide plate 110, and a second end may be free.

[0046] In a specific implementation, at least one first branch 130 may be provided at the outer edge of the first guide plate 110, and the at least one first branch 130 may extend along the outer edge contour of the first guide plate 110, and the at least one first branch 130 may be fixedly connected to the first guide plate 110.

[0047] Reference Figure 6 , Figure 6 A schematic diagram of the direction of the induced current of the guide plate structure provided by a possible embodiment of the present application is shown. Figure 5 and Figure 6 As shown, the director plate structure provided in 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, 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 110, and 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 director plate 110, so that the setting of the first branch 130 can achieve wave transmission of the first director plate 110, and the high-frequency antenna in the multi-frequency antenna can generate an induced current J1 on the second branch 140, 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 120, and the induced current J1 and the induced current J2 can offset each other, which is equivalent to not generating an induced current on the second director plate 120, so that the setting of the second branch 140 can achieve wave transmission of the second director plate 120, thus, 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, there is no direct electrical connection between the director structure and the low-frequency antenna, and the arrangement of the first branch 130 and the second branch 140 has little effect on the impedance matching between the director structure and the low-frequency antenna, and has little effect on the radiation performance of the low-frequency antenna.

[0048] As a possible implementation, the guide plate structure may include four second guide plates 120, specifically, the four second guide plates 120 may be arranged around the axial direction of 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, and the bandwidth of the low frequency antenna may be expanded. 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 gathered together, and a cross-shaped gap may be formed between the other ends of the four second guide plates 120.

[0049] In a possible specific implementation, the first branch 130 may be fixedly connected to the area between two adjacent second guide plates 120 on the first guide plate 110, and the area may be fixedly connected to two first branch 130. Figure 1 As shown, when the guide plate structure includes four second guide plates 120 , the outer edge of the first guide plate 110 can be fixedly connected to eight first branches 130 along the circumferential direction.

[0050] When the first branch 130 is specifically connected, the first branch 130 can be fixedly connected to the first guide plate 110 through the first connecting member 150. Specifically, one end of the first connecting member 150 can be fixedly connected to one end of the first branch 130, and the other end of the first connecting member 150 can be fixedly connected to the first guide plate 110, so as to realize the fixed connection between the first branch 130 and the first guide plate 110. The first branch 130 and the first connecting member 150 can be welded to realize the fixed connection, and the first connecting member 150 and the first guide plate 110 can also be welded to realize the fixed connection; or, the first branch 130, the first connecting member 150 and the first guide plate 110 can be integrally formed; or, the first branch 130 and the first connecting member 150 can be integrally formed, and the first connecting member 150 and the first guide plate 110 can be welded; or, the first connecting member 150 and the first guide plate 110 can be integrally formed, and the first branch 130 and the first connecting member 150 can be welded.

[0051] Reference Figure 7 , Figure 7 A schematic diagram of the structure of the second branch of the guide plate structure provided by a possible embodiment of the present application is shown. Figure 5 and Figure 7As shown, 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 in parallel with the first section 141, and the first section 141 and the second section 142 may be fixedly connected through 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, and the third section 143, the first section 141 and the second section 142 may form a second branch 140 with a U-shaped structure as a whole. The first end of the second guide plate 120 has an opening 121, and the second guide plate 120 can also be regarded as 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 offset each other, thereby achieving wave transmission of the second guide plate 120. When the second branch 140 is specifically connected, the third section 143 can be fixedly connected to the second guide plate 120, so that the second branch 140 and the second guide plate 120 are fixedly connected.

[0052] In actual configuration, the third section 143 can be fixedly connected to the second guide plate 120 through the second connecting member 160. Specifically, one end of the second connecting member 160 can be fixedly connected to the third section 143, and the other end of the second connecting member 160 can be fixedly connected to the second guide plate 120, so as to achieve fixed connection between the third section 143 and the second guide plate 120, thereby achieving fixed connection between the second branch 140 and the second guide plate 120. The third section 143 and the second connecting member 160 can be welded to achieve fixed connection, and the second connecting member 160 and the second guide plate 120 can also be welded to achieve fixed connection; or, the third section 143, the second connecting member 160 and the second guide plate 120 can be integrally formed; or, the third section 143 and the second connecting member 160 can be integrally formed, and the second connecting member 160 and the second guide plate 120 can be welded; or, the second connecting member 160 and the second guide plate 120 can be integrally formed, and the third section 143 and the second connecting member 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 that the layout space within the opening 121 of the second guide plate 120 can be effectively utilized.

[0053] In a possible specific implementation, the first guide plate 110 may be circular. The through hole 111 may be a circular hole. In this case, the first guide plate 110 is specifically annular. The first direction and the second direction may be radial directions of the through hole 111, that is, the first direction may be radial directions of the through hole 111, and the second direction may also be radial directions of the through hole 111. 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. Thus, the first branch 130 may 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.

[0054] Reference Figure 8 , Figure 8 FIG. 2 shows a schematic structural diagram of a guide plate structure provided by another possible embodiment of the present application. Figure 8 As shown, the first guide piece 110 can be square. The through hole 111 can be a square hole. In this case, the first guide piece 110 is specifically a square ring. The first direction and the second direction can 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 specific implementation, the first branch 130 can be fixedly connected to the side length of the square first guide piece 110. The side length of the square first guide piece 110 is a straight line. The first branch 130 extends along the outer edge contour of the first guide piece 110. Therefore, 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 piece 110 have similar paths and opposite directions, and can offset each other, so that the first guide piece 110 can be wave-transmitted.

[0055] Reference Fig. 9 , Fig. 9 FIG. 2 shows a schematic structural diagram of a guide plate structure provided by another possible embodiment of the present application. Fig. 9 As shown, the first guide plate 110 may be a square. The through hole 111 may be a square hole. In this case, the first guide plate 110 is specifically a square ring, which is different from Figure 8In the embodiment shown, the first direction and the second direction can be the directions of the side length of the through hole 111, respectively, and the first direction and the second direction are perpendicular to each other. In specific implementation, similarly, 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, and the first branch 130 extends along the outer edge contour of the first guide plate 110, so that the first branch 130 can be a linear structure, and 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, so that the first guide plate 110 can be wave-transmitted.

[0056] 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.

[0057] In one embodiment, the first guide piece 110 may be circular, and the through hole 111 may be a square hole. In this case, the first guide piece 110 is specifically an annular shape with an outer circle and an inner square. The first direction and the second direction may be 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 outer edge contour of the entire first guide piece 110 is circular, the outer edge contour of a part of the first guide piece 110 is arc-shaped, and the first branch 130 extends along the outer edge contour of the first guide piece 110. Therefore, the first branch 130 may be an arc-shaped structure.

[0058] In another embodiment, the first guide piece 110 may be circular, and the through hole 111 may be a square hole. In this case, the first guide piece 110 is specifically an annular shape with an outer circle and an inner square. Different from the previous embodiment, the first direction and the second direction may be directions of the side length 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 contour of the entire first guide piece 110 is circular, the outer edge contour of a part of the first guide piece 110 is arc-shaped, and the first branch 130 extends along the outer edge contour of the first guide piece 110, so that the first branch 130 may be an arc-shaped structure.

[0059] In another embodiment, the first guide piece 110 may be square, and the through hole 111 may be a circular hole. In this case, the first guide piece 110 is specifically an annular shape with a square outside and a circular inside. The first direction and the second direction may be radial directions of the through hole 111, respectively, that is, the first direction may be radial directions of the through hole 111, and the second direction may 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 may be fixedly connected to the side length of the square first guide piece 110, and the side length 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, and thus, the first branch 130 may be a linear structure.

[0060] 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 application. Of course, other feasible implementations can also be used in actual applications and can be specifically set according to actual conditions.
