[0002] Base station antennas in mobile communication networks are usually fixed using antenna masts. An antenna mast is a structure used to support and fix base station antennas. Generally, base station antennas are fixed to the antenna mast through clamps, enabling the base station antennas to be stably suspended in the air for wireless signal transmission and reception. This structure is commonly used in the construction of communication base stations to ensure that base station antennas can effectively cover and serve a specific area. The design and manufacture of antenna masts need to consider various factors, including the strength of materials, the stability of the structure, and the ability to adapt to different environmental conditions. In addition, the selection of base station antennas is closely related to the application environment. For example, in different environments such as urban areas, dense urban areas, suburban areas, rural areas, and transportation arteries, the selection of base station antennas will vary. For instance, low-altitude coverage antennas or ground coverage antennas may be selected to meet their respective communication requirements and environmental characteristics.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will describe the specific embodiments of the present utility model in detail with reference to the drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0025] It should be noted that the orientation or positional relationship indicated by various orientation terms is based on the orientation or positional relationship shown in the drawings. This is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0026] In addition, the terms "first", "second", etc. in the description and claims of the present invention are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence; and, without conflict, the embodiments and features in the embodiments of the present invention can be arbitrarily combined with each other. Those of ordinary skill in the art should understand that the drawings provided herein are for illustrative purposes only and are not necessarily drawn to scale. It should be understood that when an element is referred to as being "connected" or "coupled" to another element, it can be directly connected or coupled to the other element or there may be intervening elements.

[0027] Currently, the number of antenna masts on the base station is limited. With the development of the mobile communication network, different network systems of various equipment manufacturers and operators coexist, resulting in the antennas on the base station often being extremely crowded, and even in a situation where there is nowhere to install them. The demand for low-altitude coverage antennas has exacerbated this phenomenon. Moreover, low-altitude coverage antennas usually emit towards the sky, and the settings of the elevation angle and azimuth angle may be different from those of ground coverage antennas, and the two cannot share the antenna mast. In addition, since the lease of the iron tower involves the charging for the number of antenna masts occupied, more antennas also mean higher rent, bringing more cost pressure. To solve the foregoing problems, the present invention provides an antenna mast that can realize the sharing of multiple antennas, which can take into account the wireless communication coverage requirements of low-altitude coverage antennas and ground coverage antennas, and will be described in detail below through specific embodiments.

[0028] As Figures 1 to 4 shown, an embodiment of the present invention provides an antenna mast 100, including: a mast body 101, at least two horizontal support rods 103, and at least two horizontal connecting rods 106.

[0029] Wherein, one end of each horizontal support rod 103 is connected to the mast body 101 through a mast connecting piece 102. The other end of each horizontal support rod 103 is connected to one end of a horizontal connecting rod 106 through a horizontal rotating member 104, and the horizontal rotating member 104 is used to drive the connected horizontal connecting rod 106 to perform a rotating motion in the horizontal plane. The other end of each horizontal connecting rod 106 is connected to a set of base station antennas 200 through a vertical rotating member 107, and the vertical rotating member 107 is used to drive the connected base station antennas 200 to perform a pitching motion in the vertical plane.

[0030] In this embodiment, each of the horizontal rotating members 104 is independently arranged and does not interfere with each other. Therefore, the azimuth angles of each set of base station antennas 200 can be adjusted respectively through the respective horizontal rotating members 104. Each of the vertical rotating members 107 is also independently arranged and does not interfere with each other. Therefore, the elevation angles of each set of base station antennas 200 can be adjusted respectively through the respective vertical rotating members 107, so that different base station antennas installed on the same antenna mast can adjust the azimuth angle and elevation angle respectively, effectively taking into account the wireless communication coverage requirements of low-altitude coverage antennas and ground coverage antennas.

[0031] In a specific embodiment, the mast connecting member 102 is a mast clamp.

[0032] In a specific embodiment, as Figure 1 and Figure 3 shown, at least two horizontal support rods 103 are arranged in parallel and spaced apart.

[0033] In this embodiment, since one end of each of the horizontal support rods 103 is fixed to the mast body 101, after each of the horizontal support rods 103 is arranged in parallel, each of the horizontal support rods 103 will be spaced apart along the length direction of the mast body 101 to save space. As for the distance between two adjacent horizontal support rods 103, it can be set according to the size of the base station antenna, and it is ensured that adjacent base station antennas do not affect each other when adjusting their respective azimuth angles and elevation angles.

[0034] In a specific embodiment, the antenna mast 100 further includes: at least one vertical support rod 105. The other ends of every two adjacent horizontal support rods 103 are also connected to both ends of a vertical support rod 105 through two horizontal rotating members 104 connected thereto.

[0035] In this embodiment, every two adjacent horizontal support rods 103 are supported and reinforced by a vertical support rod 105 to increase the strength of the entire antenna mast.

[0036] In practical applications, the numbers of the horizontal support rods 103, the horizontal connecting rods 106 and the vertical support rods 105 are related to the number of sets of base station antennas sharing the same antenna mast. Specifically, N sets of base station antennas require N horizontal support rods 103, N horizontal connecting rods 106 and N - 1 vertical support rods 105, where N is an integer greater than or equal to 2.

[0037] The specific structure of the antenna mast will be described below through two examples.

[0038] Example 1:

[0039] As Figure 1 and Figure 2As shown in the figure, the antenna mast 100 includes a mast body 101, two horizontal support rods 103, two horizontal connecting rods 106, and one vertical support rod 105. One end of each horizontal support rod 103 is connected to the mast body 101 through a mast connector 102, with a total of two mast connectors 102; the other end of each horizontal support rod 103 is connected to one end of a horizontal connecting rod 106 through a horizontal rotating member 104, with a total of two horizontal rotating members 104; the other end of each horizontal connecting rod 106 is connected to a set of base station antennas 200 through a vertical rotating member 107, with a total of two vertical rotating members 107. Two sets of base station antennas 200 share one antenna mast 100.

[0040] Example 2:

[0041] As Figure 3 and Figure 4 As shown in the figure, the antenna mast 100 includes a mast body 101, three horizontal support rods 103, three horizontal connecting rods 106, and two vertical support rods 105. One end of each horizontal support rod 103 is connected to the mast body 101 through a mast connector 102, with a total of three mast connectors 102; the other end of each horizontal support rod 103 is connected to one end of a horizontal connecting rod 106 through a horizontal rotating member 104, with a total of three horizontal rotating members 104; the other end of each horizontal connecting rod 106 is connected to a set of base station antennas 200 through a vertical rotating member 107, with a total of three vertical rotating members 107. Three sets of base station antennas 200 share one antenna mast 100.

[0042] In a specific embodiment, the horizontal rotating member 104 includes a first outer fixed part and a first inner rotating part.

[0043] Among them, the first outer fixed part is a hollow structure, and the first inner rotating part is arranged inside the first outer fixed part, and the two are rotatably connected horizontally. The other end of the horizontal support rod 103 is fixedly connected to the outer surface (i.e., the side surface) of the first outer fixed part, the top of the vertical support rod 105 is fixedly connected to the bottom surface of the first outer fixed part of a horizontal rotating member 104, the bottom of the vertical support rod 105 is fixedly connected to the top surface of the first outer fixed part of an adjacent horizontal rotating member 104, a horizontally extending through hole is formed in the first outer fixed part, one end of the horizontal connecting rod 106 passes through the horizontally extending through hole in the first outer fixed part and is fixedly connected to the first inner rotating part. As for the length of the horizontally extending through hole, it is related to the azimuth angle of the base station antenna 200, and the width of the horizontally extending through hole is related to the thickness of the horizontal connecting rod 106.

[0044] In this embodiment, the first inner rotating part of the horizontal rotating member 104 rotates horizontally to drive the connected horizontal connecting rod 106 to rotate in the horizontal plane, thereby independently adjusting the azimuth angle of the base station antenna.

[0045] In a specific embodiment, the antenna mast 100 further includes: a first driving mechanism (not shown in the figure). The first driving mechanism is connected to the horizontal rotating member 104 and is used to drive the first inner rotating part in the horizontal rotating member 104 to rotate horizontally at a preset angle.

[0046] In this embodiment, in addition to the maintenance personnel manually adjusting the horizontal rotation angle of the horizontal connecting rod 106 to further adjust the azimuth angle of the base station antenna, the automatic adjustment of the azimuth angle of the base station antenna can also be realized through a specific driving mechanism (such as a motor).

[0047] It should be noted that the horizontal rotation refers to the rotation around the vertical axis (such as the Z-axis).

[0048] In a specific embodiment, as Figures 1 to 4 shown, the base station antenna 200 includes an antenna body 201 and an antenna bracket 202. One side of the antenna bracket 202 is connected to the back of the antenna body 201, and the other side of the antenna bracket 201 is connected to the vertical rotating member 107 through an antenna bracket connecting member (not shown in the figure).

[0049] In this embodiment, the vertical rotating member 107 drives the antenna bracket 202 to perform a pitching motion in the vertical plane through the antenna bracket connecting member, thereby adjusting the pitching angle of the antenna body 201.

[0050] In a specific embodiment, the vertical rotating member 107 includes a second outer fixed part and a second inner rotating part.

[0051] Among them, the second outer fixed part is a hollow structure, the second inner rotating part is arranged inside the second outer fixed part, and the two are longitudinally rotatably connected. The other end of the horizontal connecting rod 106 is fixedly connected to the outer surface of the second outer fixed part. A longitudinally extending through hole is formed in the second outer fixed part, and the antenna bracket connecting member passes through the longitudinally extending through hole in the second outer fixed part and is fixedly connected to the second inner rotating part. As for the length of the longitudinally extending through hole, it is related to the pitching angle of the base station antenna, and the width of the longitudinally extending through hole is related to the thickness of the antenna bracket connecting member.

[0052] In this embodiment, the second inner rotating part of the vertical rotating member 107 rotates longitudinally to drive the connected antenna bracket connecting member to perform a pitching motion in the vertical plane, thereby independently adjusting the pitching angle of the base station antenna.

[0053] In a specific embodiment, the antenna mast 100 further includes: a second driving mechanism (not shown in the figure). The second driving mechanism is connected to the vertical rotating member 107 and is configured to drive the second inner rotating portion in the vertical rotating member 107 to rotate longitudinally at a preset angle.

[0054] In this embodiment, in addition to the operation and maintenance personnel manually adjusting the vertical rotation angle of the antenna mast to further adjust the elevation angle of the base station antenna, the automatic adjustment of the elevation angle of the base station antenna can also be achieved through a specific driving mechanism (such as a motor).

[0055] It should be noted that the longitudinal rotation refers to the rotation around the horizontal axis (such as the X-axis).

[0056] The antenna mast provided by the embodiment of the present utility model vertically expands the existing antenna mast. The expanded antenna mast includes components such as a horizontal support rod, a horizontal connecting rod, a vertical support rod, a horizontal rotating member, a vertical rotating member, and a mast connecting member. Among them, the horizontal support rod is connected to the mast body and fixed using the mast connecting member. The adjacent two horizontal support rods are reinforced by the vertical support rod. A horizontal rotating member is provided between the horizontal support rod and the horizontal connecting rod to adjust the azimuth angle of the base station antenna. A vertical rotating member is provided between the horizontal connecting rod and the base station antenna to adjust the elevation angle of the base station antenna, realizing the separate adjustment of the azimuth angle and elevation angle of different base station antennas, enabling different base station antennas to share the same antenna mast, and thus being able to take into account the wireless communication coverage requirements of low-altitude coverage antennas and ground coverage antennas.

[0057] The embodiment of the present utility model also provides a base station antenna system, including: the aforementioned antenna mast, and at least two sets of base station antennas connected to the antenna mast.

[0058] In a specific embodiment, at least two sets of base station antennas include at least one set of low-altitude coverage antennas and at least one set of ground coverage antennas.

[0059] In the base station antenna system provided by the embodiment of the present utility model, since different base station antennas can share the same antenna mast, and the different base station antennas on the same antenna mast can independently adjust their respective azimuth angles and elevation angles, it avoids the dilemma of having nowhere to install the base station antenna, reduces the congestion degree of the antenna masts on the tower, greatly saves the number of antenna masts, correspondingly reduces the rent for the antenna occupying the mast, and can also take into account the wireless communication coverage requirements of low-altitude coverage antennas and ground coverage antennas.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
