Description

[Technical Field]

[0001] The present invention relates to an antenna installation device, and more particularly to an antenna installation device capable of adjusting and maintaining the tilt angle of a radio wave direction of a base station antenna. [Background technology]

[0002] Generally, an antenna is a device that converts electromagnetic waves into space and receives them, and is an essential device for transmitting and receiving information wirelessly. Recently, as the demand for mobile communications has exploded, various types of mobile communication antennas are readily found installed in base stations, repeaters, etc. to achieve communication goals. For efficient transmission and reception of radio waves, it is highly necessary for these mobile communication antennas to be installed and maintained in a direction that allows for optimal transmission and reception ratios.

[0003] In this regard, Korean Patent Registration No. 10-0862143 (September 30, 2008) proposes a fixing device that provides an adjustment function, and as shown in FIG. 1, a fixing device (26) is provided that includes a body clamp (22) that is connected to the support (14) so ​​that the antenna (16) can be fixed to the support (14), a slide bracket (40) that is disposed widthwise on the back of the antenna (16) corresponding to the frequency radiation surface and is spaced apart in the vertical direction, and a guide slot (44) that is formed on the slide bracket (40) and connects to the body clamp (22) so that the fixing bracket (32) can be movably connected, and that allows the antenna (16) to move horizontally around the support (14) and be adjusted left and right.

[0004] In the proposed technology, the fixing bracket 32 ​​is provided with a plurality of hinged link members that can be folded, so the installation direction of the antenna 16 can be adjusted up and down, and the installation direction of the antenna 16 can be adjusted left and right by horizontal movement using the guide slot 44. Therefore, the installation direction of the antenna can be adjusted.

[0005] However, in this case, the adjustment of the installation direction of the antenna 16 using the guide slot 44 does not deviate significantly from the width of the antenna 16, and the installation direction cannot be adjusted in a rotational direction around the support pole 14, resulting in a limited range of displacement. The force that maintains the installation state of the adjusted installation direction of the antenna 16 against external forces such as wind can be seen as the friction force between the slide bracket 40 and the fixed bracket 32, which are connected by the guide slot 44. However, on rooftops of buildings or mountaintops, where mobile communication base stations are typically installed, this friction force has limitations in overcoming high wind speeds. Furthermore, the connection between the body clamp 22 and the fixed bracket 32 ​​and the connection between the link members that form the slide bracket 40 are both made by hinge connections 34 using bolts and nuts, but these also have limitations in overcoming strong wind speeds.

[0006] Meanwhile, there has been a recent shift from fourth-generation mobile communications (4G Networks) to fifth-generation mobile communications (5G Networks), which have speeds reaching up to 20Gbps. Unlike 4G, which uses frequencies below GHz, 5G transmits data at high speeds using a wide bandwidth of several hundred MHz or more in the high frequency bands of centimeter waves (3GHz to 30GHz) and millimeter waves (30GHz to 300GHz).

[0007] However, because 5G utilizes the millimeter wave (mmWAVE) frequency band above 24 GHz, signals have properties similar to light and cannot avoid obstacles like mountains and buildings. Furthermore, because wavelengths are only 1-10 mm, the coverage area within which base stations can transmit and receive frequencies is narrow, and high-frequency signals must be concentrated in one direction, resulting in significant energy consumption during signal transmission and reception. Furthermore, existing 4G mobile communication antennas are separate from the transmitter and receiver and weigh 9-16 kg, while 5G mobile communication antennas are integrated and combined with the transmitter and receiver, weighing 20-25 kg. Therefore, when 5G mobile communication antennas are installed on pre-installed poles on building roofs or parapets, such as a single pole over 3 meters long or a monopole under 2 meters long, they must be installed at a height of 2 meters or less for safety reasons, depending on their weight. Therefore, for 5G mobile communication antennas, setting and maintaining the installation direction is even more important than for existing 4G mobile communication antennas, considering the efficient transmission and reception of frequency signals and safety.

[0018] The above and additional aspects will become clearer through the following examples. In this specification, corresponding elements in each drawing are referred to by the same numerals. Furthermore, the shapes and sizes of elements may be exaggerated. Furthermore, if a description of related known technology is considered to unnecessarily obscure the gist of the present invention, the description of that known technology will be omitted.

Meanwhile, Fig. 5 illustrates the operation of the antenna installation device according to an embodiment of the present invention.

[0020] The configuration and operation of the antenna installation device according to the present invention will be described with reference to FIGS.

[0021] The antenna installation device 1 according to the present invention includes an upper body clamp 10 , a lower body clamp 20 , an upper antenna bracket 30 , a lower antenna bracket 40 , a lower support bracket 50 , and an angle adjustment member 60 .

[0022] The upper body clamp 10 and the lower body clamp 20 are connected to a support or the like so that the antenna 3 can be fixed. The upper body clamp 10 and the lower body clamp 20 are provided with fixing members 11 that can tighten or loosen each body clamp 10, 20, so that the upper and lower installation positions of the upper body clamp 10 and the lower body clamp 20 relative to the support 2 can be freely adjusted.

[0023] The upper antenna bracket 30 is coupled to the upper rear surface of the antenna 3, and the lower antenna bracket 40 is coupled to the lower rear surface of the antenna 3. The upper antenna bracket 30 may be made of stainless steel or the like, which enhances corrosion resistance.

[0024] The lower support bracket 50 is connected to the lower body clamp 20 on one side and to the lower antenna bracket 40 on the other side, with at least one of them being hinged. In the drawing of Figure 4, the lower support bracket 50 is shown hingedly connected to the lower antenna bracket 40. The lower support bracket 50 may be a "U" shaped bracket.

[0025] The angle adjustment member 60 includes a pair of a first fixed link 61 having one end hingedly connected to the upper body clamp 10, a second fixed link 62 having one end hingedly connected to the upper antenna bracket 30, and a pair of a first adjustment link 63 having one end hingedly connected to the center of the first fixed link 61 and a second adjustment link 64 having one end hingedly connected to the center of the second fixed link 62. The first fixed link 61 and the second fixed link 62 are hinged to each other, and the first adjustment link 63 and the second adjustment link 64 are hinged to each other.

[0026] The angle adjusting member 60 formed as above is hinged to the upper body clamp 10 on one side and to the upper antenna bracket 30 on the other side.

[0027] The antenna installation device 1 constructed as described above can easily adjust the directivity angle of the antenna 3 by narrowing or widening the angle adjusting member 60, and can firmly and stably maintain the adjusted tilt angle. Meanwhile, the angle of the antenna 3 can be adjusted up to 35° clockwise from the front.

[0028] Meanwhile, an angle adjustment rod 65 may be further included, which is connected by passing through the hinge connection portions of the first fixed link 61 and the second fixed link 62 and the hinge connection portions of the first adjustment link 63 and the second adjustment link 64, and a screw thread (not shown) may be formed on the outer circumferential surface of the angle adjustment rod 65, so that the angle of the angle adjustment member 60 can be adjusted by rotating the angle adjustment rod 65 forward or backward. That is, by rotating the angle adjustment rod 65 clockwise or counterclockwise, the antenna 3 faces forward or downward.

[0029] A rotation nut 65a having a hexagonal head may be provided at one end of the angle adjustment rod 65. When the rotation nut 65a is provided at one end of the angle adjustment rod 65 in this manner, the angle adjustment rod 65 can be easily rotated using this rotation nut 65a. A loosening prevention nut may be provided at the other end of the angle adjustment rod 65.

[0030] In addition, a protractor 51 may be provided on one side of the lower support bracket 50. When the protractor 51 is provided on one side of the lower support bracket 50, the rotation angle is displayed, making it easy to identify the rotation angle.

[0031] Furthermore, although not shown, a through-hole may be formed at one end of the angle adjustment rod 65 instead of the rotation nut 65a. In this case, the angle of the antenna 3 can be easily adjusted by inserting a rod into the through-hole and turning the rod to rotate the angle adjustment rod 65. The angle adjustment rod 65 may also be formed in an "inverted L" shape with a handle formed at one end. In this case, the angle adjustment rod 65 can be rotated by gripping the handle, making it even easier to adjust the angle of the antenna 3.

[0032] FIG. 6 shows an upper body clamp 10 according to one embodiment of the present invention before it is fastened to a support, and FIG. 7 shows the upper body clamp 10 shown in FIG. 6 connected to a support 2.

[0033] 6 and 7, the upper body clamp 10 includes an "L"-shaped fixed member 11 having a curved inner surface, a connecting rod 12 hinged to one end of the fixed member 11 and having a thread formed on its outer surface, a nut 13 fastened to the connecting rod 12, and a rotating member 14 having a curved inner surface, a hinged to the other end of the fixed member 11, and having a mounting protrusion 14a with a mounting groove 14b at one end into which the connecting rod 12 can be attached.

[0034] To connect the upper body clamp 10 constructed as described above to a cylindrical member such as a support pillar, first, the inner peripheral surface of the fixed member 11 is brought into contact with the cylindrical member, and the rotating member 14 is rotated so that the rotating member 14 covers the cylindrical member. Then, the connecting rod 12 is inserted into the mounting groove 14b of the rotating member 14, and the nut 13 is tightened so that the nut 13 presses against the mounting protrusion 14a. As the nut 13 presses against the mounting protrusion 14a, the inner peripheral surfaces of the fixed member 11 and the rotating member 14 are tightly connected to the cylindrical member such as a support pillar 2.

[0035] When using the upper body clamp 10 configured and operating as described above, it is easy to fasten the upper body clamp 10 to the support. Meanwhile, the lower body clamp 20 may also have the same configuration.

[0036] While the present invention has been described with reference to the embodiments illustrated in the accompanying drawings, these are merely illustrative, and those skilled in the art will recognize that various modifications and equivalent embodiments are possible. Therefore, the true scope of the present invention should be determined solely by the appended claims. [Explanation of symbols]
