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] In general, an antenna means a conversion device for transmitting or receiving electromagnetic waves in space, and is an essential device for wirelessly transmitting and receiving information. In recent years, as the demand for mobile communication has increased explosively, it is easy to find various types of mobile communication antennas installed in base stations, repeaters, etc. to achieve communication purposes. There is a high need for such mobile communication antennas to be installed and maintained in a direction that provides an optimal transmission and reception ratio for efficient transmission and reception of radio waves.

[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 is 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 connects to the body clamp 22 so that a fixing bracket 32 ​​is movably connected thereto, and the antenna 16 moves 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 plurality of hinged link members, so that the installation direction of the antenna 16 can be adjusted in the vertical direction, and the installation direction of the antenna 16 can be adjusted in the left-right direction 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 significantly change the width of the antenna 16, and it is impossible to adjust the installation direction in the rotational direction around the support 14, so there is a problem that the displacement range 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 generally, on the rooftops of buildings or mountaintops where mobile communication base stations are mainly installed, there is a limit to how much such friction force can withstand high wind speeds. Also, the connections between the body clamp 22 and the fixed bracket 32 ​​and the connections between the link members forming the slide bracket 40 are all made by hinge connections 34 using bolts and nuts, but this also has a problem of being limited in its ability to withstand high wind speeds.

[0006] Meanwhile, there has been a recent shift from fourth-generation mobile communications (4G Network) to fifth-generation mobile communications (5G Network), with maximum speeds reaching 20 Gbps. 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 (3 GHz to 30 GHz) and millimeter waves (30 GHz to 300 GHz).

[0007] However, when 5G uses the millimeter wave (mmWAVE) frequency band of 24 GHz or more, the signal becomes closer to the nature of light and cannot avoid obstacles such as mountains and buildings, the wavelength is only 1-10 mm, the area (coverage) in which each base station can transmit and receive the frequency is narrow, and high frequency signals must be sent in one direction together, otherwise a lot of energy is consumed to transmit and receive the signal. In addition, conventional 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 poles over 3 meters or mono poles under 2 meters that are already installed on the rooftop or handrail of a building, they must be installed under 2 meters for safety reasons depending on their weight. Therefore, for 5G mobile communication antennas, it is more important to set and maintain the installation direction compared to conventional 4G mobile communication antennas, taking into account efficient transmission and reception of frequency signals and security.

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

[0018] The configuration and operation of the antenna installation device according to the present invention will be described with reference to FIGS.

[0019] 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.

[0020] The upper body clamp 10 and the lower body clamp 20 are coupled to a support or the like so as to fix the antenna 3. The upper body clamp 10 and the lower body clamp 20 are provided with bolts 11 and 21 for tightening and loosening the body clamps 10 and 20, respectively, 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.

[0021] The upper antenna bracket 30 is coupled to the upper rear part of the antenna 3, and the lower antenna bracket 40 is coupled to the lower rear part of the antenna. The upper antenna bracket 30 can be made of SUS or the like. In this case, corrosion resistance is enhanced.

[0022] 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 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.

[0023] The angle adjustment member 60 includes a pair of a first fixed link 61 having one side hinged to the upper body clamp 10 and a second fixed link 62 having one side hinged to the upper antenna bracket 30, and a pair of a first adjustment link 63 having one side hinged to the first fixed link 61 and a second adjustment link 64 having one side hinged to 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.

[0024] 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.

[0025] The antenna installation device 1 formed 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° clockwise from the front.

[0026] Meanwhile, an angle adjustment rod 65 is 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) is 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 or counter-rotating the angle adjustment rod 65.

[0029] 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 easier to adjust the angle of the antenna.
