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 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 wirelessly transmitting and receiving information. As the demand for mobile communications has recently increased explosively, it is easy to find various types of mobile communication antennas installed in base stations, repeaters, etc. to achieve communication purposes. For efficient transmission and reception of radio waves, it is highly necessary for such mobile communication antennas to be installed and maintained in a direction that can obtain an optimal transmission and reception ratio.

[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 a support (14) so ​​that an antenna (16) can be fixed to the support (14), a slide bracket (40) that is disposed in the width direction on the back surface of the antenna (16) corresponding to the frequency radiation surface and is provided with a gap in the vertical direction, and a guide slot (44) that is formed on the slide bracket (40) and is connected to the body clamp (22) so that the fixing bracket (32) can be movably connected, and the antenna (16) can move horizontally around the support (14) to be adjusted in the left and right directions.

[0004] In the proposed technology, the fixing bracket 32 ​​is provided foldably with a number of hinged link members, so that 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 adjustment of the installation direction in the rotational direction around the support (14) is impossible, so there is a problem that the range of displacement is small, and the force that maintains the installation state of the antenna (16) whose installation direction has been adjusted against external forces such as wind can be seen as the friction force between the slide bracket (40) and the fixed bracket (32) connected by the guide slot (44), but there is a limit to how much such friction force can overcome high wind speeds on the rooftops of buildings or mountain tops where mobile communication base stations are usually installed. In addition, 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 there is also a problem that this also has a limit to how much it can overcome strong wind speeds.

[0006] Meanwhile, there has been a shift from fourth-generation mobile communications (4G Networks) to fifth-generation mobile communications (5G Networks) with maximum speeds reaching 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, when 5G uses the millimeter wave (mmWAVE) frequency band of 24 GHz or higher, the signal is close to the properties of light and cannot avoid obstacles such as mountains and buildings, and the wavelength is only 1-10 mm, so the area (coverage) in which each base station can transmit and receive frequencies is narrow, and there is a problem that a lot of energy is consumed to transmit and receive signals unless high-frequency signals are gathered in one direction. In addition, existing 4th generation (4G) mobile communication antennas are separated from the transmitter and receiver and weigh 9-16 kg, while 5th generation (5G) mobile communication antennas are integrated antennas combined with the transmitter and receiver and weigh 20-25 kg. Therefore, when installing 5th generation (5G) mobile communication antennas on one pole exceeding 3 meters or mono pole less than 2 meters among the installation poles installed in advance on the roof or parapet of a building, they must be installed less than 2 meters for safety depending on their weight. Therefore, for 5G mobile communication antennas, it is even more important to set and maintain the installation direction compared to existing 4G mobile communication antennas, taking into consideration efficient transmission and reception of frequency signals and security.

[0018] The above and additional aspects will become clear through the following examples. In this specification, corresponding components in each drawing are referred to by the same numerals. Also, the shape and size of the components may be exaggerated. And, if the description of related known technology is considered to be likely to unnecessarily obscure the gist of the present invention, the description of the 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 coupled 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 of the body clamps 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 part of the rear surface of the antenna 3, and the lower antenna bracket 40 is coupled to the lower part of the rear surface of the antenna 3. The upper antenna bracket 30 may be made of SUS or the like. In this case, corrosion resistance is enhanced.

[0024] The lower support bracket 50 has one side connected to the lower body clamp 20 and the other side connected to the lower antenna bracket 40, at least one of which is hinged. In the drawing of Fig. 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 hinged to the upper body clamp 10, a second fixed link 62 having one end hinged to the upper antenna bracket 30, and a pair of a first adjustment link 63 having one end hinged to the center of the first fixed link 61, and a second adjustment link 64 having one end hinged 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 adjustment member 60 formed as above is hinged to the upper body clamp 10 at one side and to the upper antenna bracket 30 at the other side.

[0027] The antenna installation device 1 constructed as above can easily adjust the directional angle of the antenna 3 by narrowing or widening the angle adjustment 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° in the clockwise direction based on the front.

[0028] Meanwhile, an angle adjustment rod 65 may be further included which is connected by penetrating through the hinge connection parts of the first fixed link 61 and the second fixed link 62 and the hinge connection parts 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, the antenna 3 faces forward or downward by rotating the angle adjustment rod 65 clockwise or counterclockwise.

[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, so that the rotation angle can be easily identified.

[0031] Also, 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 corresponding through hole and turning the rod to rotate the angle adjustment rod 65. Also, the angle adjustment rod 65 may 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 pillar, and FIG. 7 shows the upper body clamp 10 shown in FIG. 6 connected to a pillar 2.

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

[0034] When the upper body clamp 10 formed as described above is to be coupled to a cylindrical member such as a 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 coupling rod 12 is fitted into the fitting groove 14b of the rotating member 14, and the nut 13 is tightened so that the nut 13 presses the fitting protrusion 14a. As the nut 13 presses the fitting protrusion 14a, the inner peripheral surfaces of the fixed member 11 and the rotating member 14 are fitted closely to the cylindrical member such as the 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 a support pole. Meanwhile, the lower body clamp 20 may also have the same configuration.

[0036] Although the present invention has been described with reference to the embodiments shown in the accompanying drawings, it will be understood that the present invention is merely illustrative and that various modifications and equivalent embodiments are possible, and therefore the true scope of the present invention should be determined only by the appended claims.
