[0002] In mobile communication systems, a "base station" refers to a system that relays radio waves from portable terminals within a cell. Base stations are primarily located on building rooftops to relay these signals. Therefore, base stations exist on a cell-by-cell basis. Besides serving as an interface between portable terminals and the switching center, these base stations also control the transmission of incoming and outgoing calls, the designation of call channels, and the monitoring of call channels at the cell level. Antenna devices used for base stations are predominantly popular due to their advantages, particularly those capable of tilting vertically or horizontally.

[0003] With the widespread adoption of mobile communication services, the availability of antenna devices that provide more stable wireless network environments is expanding. Mobile communication services have evolved from 2G (2 Generation), which only allowed wired calls, through 3G, 4G, and pre-5G, and recently 5G has become increasingly mature. These antenna devices for 5G mobile communication are packaged together with existing 4G and pre-5G devices to share their installation locations.

[0004] However, existing base station antenna devices have the following problems: the specifications of the antenna module and the remote radio head (RRH) are different, and it is difficult to connect and assemble the antennas of each frequency band provided to the antenna module with the remote radio head, thus consuming a lot of setup time and costs.

Figure 7 To show the removal Figure 1 and Figure 2 An internal perspective view of the inclined section of the guide shell in the structure.

[0059] First, to aid in understanding the base station antenna device of the present invention, the structure of the base station antenna unit will be described in detail. The base station antenna device of this embodiment includes an antenna module A1 and a remote radio head unit A2. In this embodiment, the antenna module A1 refers to any antenna module having at least one frequency band. Furthermore, the remote radio head unit A2, as described in this embodiment, refers to a device that connects to the antennas provided to each frequency band of the antenna module A1 to transmit and receive signals with the antennas and the base station. The remote radio head unit A2 is a relay device that receives weakened signals and amplifies or retransmits them between the base station and the mobile communication terminal of a mobile communication system, or normalizes distorted waveforms and readjusts timing, etc.

[0060] like Figures 1 to 4 As shown, a base station antenna device according to an embodiment of the present invention includes: an antenna module A1, which is vertically disposed with a space S separating it from the front of a vertically disposed support rod 1 at a predetermined distance, and is disposed in a manner that allows it to be tilted at a predetermined angle; a remote wireless head unit A2, which is disposed on the back of the antenna module A1 in the space S, and is disposed in a manner that allows it to be slidably mounted and dismounted in the left-right direction on the side of the space S; and an adapter 200, which is disposed at the lower end of the remote wireless head unit A2 to facilitate the electrical signal connection and disconnection between the antenna module A1 and the remote wireless head unit A2, and is provided with a pusher block 250 that allows the signal connection and disconnection to be performed by moving it in the front-back direction.

[0061] A tilting unit 100 can be provided at the upper end of the mast 1 to tilt both the antenna module A1 and the remote wireless head A2 simultaneously. The upper end of the antenna module A1 is connected to the tilting unit 100 by means of hinge rotation relative to the tilting unit 100, and the lower end of the antenna module A1 is connected to the lower end of the mast 1, which is lower than the tilting unit 100, by means of hinge rotation.

[0062] The tilting unit 100 is provided to extend a predetermined length horizontally outward from the upper end of the support rod 1. Inside the tilting unit 100, a tilting portion 101 connected to the upper end of the antenna module A1 is configured to move horizontally along with the guide arm unit 105, so that the upper end of the antenna module A1 moves according to the moving distance of the tilting portion 101, thereby adjusting the tilt angle of the antenna module A1. As described above, the upper end of the antenna module A1 can be tilted and rotated in the front-back horizontal direction with the lower end fixed rotation point as a reference, thus having the advantage of easily adjusting the directivity of the antenna beam.

[0063] More specifically, the tilting unit 100 includes a guide arm unit 105 and a tilting portion 101. The guide arm unit 105 guides the movement of the tilting portion 101, and the tilting portion 101 adjusts the tilt angle of the antenna module A1 while moving under the guidance of the guide arm unit 105.

[0064] like Figures 5 to 7 As shown, the guide arm unit 105 can be horizontally extended to one side in an orthogonal manner to the vertically arranged support rod 1. The support rod 1 can be formed in a generally hollow cylindrical shape.

[0065] like Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the pole 1 is described in a vertically arranged configuration. However, although not shown, the pole 1 may be horizontally arranged against the wall of the building. Therefore, the directional terminology used in this embodiment of the present invention is based on the vertically arranged pole 1, regardless of the actual installation direction of the pole 1.

[0066] like Figure 5 As shown, the guide arm unit 105 performs the function of guiding the movement of the tilting part 101 while limiting the movement distance of the tilting part 101.

[0067] More in detail, such as Figure 5 As shown, the guide arm unit 105 may include: a housing connector 120 for mediating engagement with the boom 1; and a guide housing 110 connected to the housing connector 120 and extending horizontally in a direction orthogonal to the boom 1.

[0068] Among them, the guiding housing 110 can be formed in a shape with a vertical cross-section of a "匚" character having an opening at the bottom. This is to prevent interference when mediating the movement of the upper rotating link 41 and the inclined portion 101 that are combined with the upper end portion of the antenna module A1.

[0069] As Figures 5 to 7 shown, the inclined portion 101 can perform the following functions: disposed within the guide arm unit 105, with reference to the lower end portion of the antenna module A1 fixed at the hinge position, within the guide arm unit 105, the upper end portion of the antenna module A1 is moved along the horizontal direction to adjust the tilt angle relative to the pole 1.

[0070] More specifically, as Figure 4 shown, the antenna module A1 is connected to the inclined portion 101 in a manner that can be hinged and rotated through the upper rotating link 41 provided at its upper end portion, and can be connected to the pole 1 in a manner that can be hinged and rotated through the lower rotating link 42 provided at its lower end portion.

[0071] Among them, as Figure 4 shown, on the pole 1, an upper coupling fixture 10 and a placement fixture 30 for mediating the coupling of the guide arm unit 105 provided in a manner that inclines the upper end portion of the antenna module A1 are provided, and at the same time, a lower coupling fixture 20 for mediating the coupling of the rotating bracket 45 provided in a manner that mediates the hinge coupling with the lower rotating link 42 connected to the lower end portion of the antenna module A1 can be provided.

[0072] The coupling of the upper rotating link 41 is hinge-coupled at one end portion of the antenna module A1 and the other end portion coupled to the inclined portion 101 in a manner that can relatively hinge-rotate, and the coupling of the lower rotating link 42 is directly thread-fastened at one end portion of the antenna module A1 in a manner that cannot hinge-rotate and is hinge-coupled at the other end portion coupled to the rotating bracket 45 in a manner that can relatively hinge-rotate. Therefore, the hinge position of the antenna module A1 connected by the upper rotating link 41 can be defined as being variable according to the position within the guide arm unit 105 of the inclined portion 101, but the hinge position of the antenna module A1 connected by the lower rotating link 42 is relatively fixed.

[0073] In addition, as Figures 5 to 7 shown, the inclined portion 101 may include: a lead screw bolt 130, which is longly provided along the length direction within the guiding housing 110 in the structure of the guide arm unit 105, and has an external thread formed on its outer peripheral surface; and an inclination driving portion 140, which moves along the lead screw bolt 130 and is hinge-connected to the upper end portion of the antenna module A1 through the upper rotating link 41.

[0074] Although the external thread formed on the lead screw bolt 130 is not shown in detail in the accompanying drawings, it may include one of the following: a ball screw shape that inserts balls of a specified size and a trapezoidal shape that facilitates gear meshing.

[0075] The lead screw bolt 130 can be fixed to one end of the inner side and the other end of the inner side of the guide housing 110, which is arranged in a horizontal direction orthogonal to the rod 1, using fixing screws (not shown).

[0076] like Figures 5 to 7 As shown, the tilting drive unit 140 may include: a drive unit housing 141, which has a defined space inside; a drive motor 143, which is disposed in a motor housing 142 attached to the drive unit housing 141 and is electrically driven; a drive gear 145, which rotates in conjunction with the rotating shaft of the drive motor 143 extending from the motor housing 142 toward the drive unit housing 141, and has teeth on its outer peripheral surface; and a moving gear 144, which has an internal thread formed at the center of rotation that allows the lead screw bolt 130 to pass through and has teeth on its outer peripheral surface that mesh with the drive gear 145.

[0077] The drive housing 141 can serve as a space for setting the drive gear 145 and the moving gear 144 by forming the space specified above. It also performs the function of partially connecting to a pair of guide rails 150 (described later) fixed to the guide housing 110, and partially connecting to the upper end of the antenna module A1 via the upper rotating link 41. As the drive motor 143 drives the receiving guide rails 150, the upper end of the antenna module A1 moves along the length direction (i.e., the horizontal direction) on the lower side of the guide housing 110 to adjust the tilt angle.

[0078] The motor housing 142 is provided in such a way that it forms a separate space on one side of the drive housing 141. Inside the motor housing 142, the drive motor 143 can be fixed in such a way that it has the aforementioned rotating shaft that is parallel to and spaced apart from the lead screw bolt 130.

[0079] The rotation shaft of the drive motor 143 extends through the inside of the motor housing 142 and is exposed inside the drive housing 141. A drive gear 145 is provided in a manner that is coaxially linked with the rotation shaft of the drive motor 143.

[0080] Among them, such as Figures 5 to 7 As shown, the tilting drive unit 140 may further include: a drive bearing support 147 that rotatably supports the drive gear 145 relative to the drive unit housing 141; and a movable bearing support 146 that rotatably supports the movable gear 144 relative to the drive unit housing 141.

[0081] The drive bearing support portion 147 and the moving bearing support portion 146 respectively perform the following functions, that is, rotatably support the drive gear 145 and the moving gear 144 that are rotatably provided within the drive unit housing 141, and can each be provided in a type with a plurality of bearing balls that reduce friction between the inner wheel in a fixed state and the outer wheel in a rotating state. Among them, the inner wheels are respectively fixed to the drive unit housing 141, and the outer wheels are provided in a manner that can rotate in conjunction with the drive gear 145 and the moving gear 144.

[0082] In addition, as Figures 5 to 7 shown, the tilt drive unit 140 may further include: a pair of tilt guide rails 150, respectively disposed on one side and the other side in the width direction of the guide arm unit 105, and extending along the length direction of the guide arm unit 105; and a pair of moving guide blocks 160, fixed to the outside of the drive unit housing 141, and coupled to the pair of tilt guide rails 150 to mediate the coupling of the drive unit housing 141.

[0083] More specifically, the pair of tilt guide rails 150 may be respectively horizontally fixed along the length direction on one side and the other side in the width direction of the guide housing 110 that is horizontally disposed along the length direction.

[0084] And the pair of moving guide blocks 160 respectively have a "C" - shaped vertical cross - sectional shape in a manner of engaging and fixing while surrounding a part of the outer surface of the pair of tilt guide rails 150, and can be respectively fixed to one outer surface and the other outer surface of the drive unit housing 141.

[0085] Figure 8 To show the exploded perspective view of the installation and removal state of the antenna module of the remote radio head in the structure of Figure 2 Figure 9 To show the cross - sectional view and partial enlarged view of the base station antenna device of the present invention, Figure 10 To show Figure 9 the cross - sectional view of the adapter in the cross - sectional view of

[0086] The antenna module A1 is provided in a long and thin box shape along the up - and - down direction. As Figure 3 and Figure 4 shown, it can be arranged parallel to the pole 1 in a manner that has a separation space S that is separated from the pole 1 by a predetermined distance in the front direction.

[0087] Referring to Figure 8 , a remote radio head A2 can be provided in the separation space S between the antenna module A1 and the pole 1. More specifically, the remote radio head A2 can be detachably coupled to the back of the antenna module A1 by sliding.

[0088] For this reason, as Figure 9As shown, at least one sliding mounting track 220 is arranged along the left-right direction on the back of the antenna module A1, and at least one sliding block 225 can be arranged on the front surface of the remote radio head end A2 facing the back of the antenna module A1, which slides in conjunction with the at least one sliding mounting track 220.

[0089] Among them, such as Figure 9 As shown, the sliding mounting track 220 includes: a guide frame 221, which is elongated along the left-right direction and disposed on the back of the antenna module A1; and a guide rod 223, which is elongated along the left-right direction and disposed on the inner side of the lower end and the inner side of the upper end of the guide frame 221. The guide rod 223 is provided such that at least a portion of its outer peripheral surface protrudes inward from the lower end and the upper end of the guide frame 221, respectively.

[0090] In addition, such as Figure 9 As shown, the sliding block 225 can be configured in the shape of a wheel with a recessed sliding groove formed on its outer peripheral surface. In the groove of the sliding block 225, the antenna module A1 of the remote radio head end A2 can be guided to slide in the left and right directions by inserting the guide rod 223 of the sliding mounting rail 220 into the groove.

[0091] At the same time, such as Figure 1 As shown, at least one fixed bracket 230 protruding towards the left and right ends of at least one sliding mounting track 220 can be provided on the side of the antenna module A1.

[0092] Among them, such as Figure 1 As shown, at least one mounting bracket 230 may include: a mounting block 231, coupled to the antenna module A1; and a rotating block 233, rotatably mounted relative to the mounting block 231, and detachably mounted to the left or right side of the remote wireless head unit A2. The rotating block 233 is configured to rotate at least 90 degrees outward relative to the mounting block 231, thereby opening one side of the sliding mounting track 220 when the remote wireless head unit A2 is moved from the side toward the sliding mounting track 220 relative to the antenna module A1 for engagement.

[0093] That is, before the remote wireless head A2 is slidably attached to the back of the antenna module A1, the rotating block 233 in at least one fixed bracket 230 is kept in a state of being rotated outward relative to the fixed block 231 fixed to the antenna module A1 for sliding attachment. After the remote wireless head A2 is slidably attached to the back of the antenna module A1, the rotating block 233 in at least one fixed bracket 230 can prevent the remote wireless head A2 from detaching in the left and right directions by engaging with the side bolts or lead screws of the remote wireless head.

[0094] In addition, such as Figures 8 to 10As shown, in one embodiment of the present invention, the adapter 200 of the base station antenna device can be configured with multiple push blocks 250 spaced apart at a predetermined distance along the left-right direction at the lower end of the remote radio head A2. In one embodiment of the present invention, the adapter 200 is configured with three push blocks 250 spaced apart at a predetermined distance along the left-right direction at the lower end of the remote radio head A2, but is not limited to the number described above.

[0095] The adapter 200, made with the structure described above, performs both electrical connection and physical locking connection with the fixed connector 217 located on the back of the antenna module A1.

[0096] More in detail, such as Figure 9 and Figure 10 As shown, the push block 250 in the structure of adapter 200 may include a locking connector 218 to enable electrical connection and physical locking with the fixed connector 217 by a push operation toward the antenna module A1 side, and to release the electrical connection and physical locking with the fixed connector 217 by a pull operation toward the opposite side of the antenna module A1 side.

[0097] like Figure 10 As shown, the push block 250 may include: a push knob 211, which allows the user to set it by pushing or pulling it by hand; and a push display 212, which prints text or symbol shapes on the outside of the push knob 211 to show how to use the push knob 211.

[0098] Before the remote radio head A2 slides onto the back of the antenna module A1, the locking connector 218 is in the pulled position to eliminate interference with the fixed connector 217. After the remote radio head A2 slides onto the back of the antenna module A1, the locking connector 218 can be in the pushed position to surround the fixed connector 217.

[0099] For this purpose, the push block 250 may further include: a guide housing 213 having a space with an opening in the direction of pushing and pulling movement; a moving block 255 configured to move while receiving guidance from the guide housing 213; and the aforementioned locking connector 218 connected to the end of the moving block 255.

[0100] The ends of the fixed connector 217 and the locking connector 218 are configured to engage in a male-female engagement by the pushing operation of the push block 250. As long as no separate external force is provided, the male-female engagement can be maintained, thereby preventing the electrical connection between the antenna module A1 and the remote radio head A2 from being arbitrarily disconnected.

[0101] In addition, as mentioned above, in order to make it easier to make electrical connection and physical locking connection between antenna module A1 and remote radio head A2 using adapter 200, and in order to make the separation space S between antenna module A1 and remote radio head A2 and the mast 1 wider by means of tilting unit 100, the upper part of antenna module A1 can be tilted forward at a predetermined angle.

[0102] However, in the base station antenna device according to an embodiment of the present invention, in the limited space S between the antenna module A1 and the support pole 1, the remote wireless head A2 can be slidably moved from the side along the left and right direction on the back of the antenna module A1 for assembly and disassembly. Therefore, it is not necessary to first perform the tilting operation through the tilting unit 100.

[0103] The embodiments of the base station antenna device and its adapter of the present invention have been described in detail above with reference to the accompanying drawings. However, the embodiments of the present invention are not limited to the above-described embodiments, and various modifications and equivalent implementations can be made by those skilled in the art to which this invention pertains, which is obvious. Therefore, the true scope of the present invention is defined by the scope of protection of the invention described below.
