The present invention relates to an antenna holding device, and more specifically, to an antenna holding device capable of allowing a radio wave orientation inclination angle of an antenna for a base station to be adjusted and maintaining the radio wave orientation inclination angle.
In general, antennas are conversion devices for transmitting or receiving electromagnetic waves through a space and are essential devices for wirelessly transmitting and receiving information. As the demand for mobile communication has recently explosively increased, it is easy to see various types of mobile communication antennas installed on base stations and relays to achieve the purpose of communication. These mobile communication antennas need to be installed and maintained in directions in which an optimal transmission and reception ratio can be obtained for efficient transmission and reception of radio waves.
In this regard, in Korean Registered Patent Publication No. 10-0862143 (Sep. 30, 2008), a fixing apparatus with an adjustment function has been proposed. As illustrated in
In the proposed technology, since the fixing bracket 32 is provided to be hinged by a plurality of link members, an installation direction of the antenna 16 may be vertically adjusted, and the installation direction of the antenna 16 may be adjusted in a left-right direction by horizontally moving the antenna 16 using the guide slot 44. Accordingly, the installation of the antenna can be adjusted.
However, in this case, since the adjustment of the installation direction of the antenna 16 using the guide slots 44 cannot significantly deviate from a width of the antenna 16 and it is impossible to adjust the installation direction in a rotational direction around the pillar 14, there is a problem of small displacement, and a force which maintains an installation state of the antenna 16 of which the installation direction is adjusted may be a frictional force between the slide bracket 40 and the fixing bracket 32 coupled through the guide slot 44, in general, there is a limit on overcoming a high wind speed using the above frictional force on a roof of a building or on top of a mountain where a base station for mobile communication is typically installed. In addition, coupling of the body clamp 22 and the fixing bracket 32 and coupling between the link members constituting the slide bracket 40 are performed by hinge-coupling (34) using bolts and nuts, which also has a problem that there is a limit on overcoming the high wind speed.
Meanwhile, recently, there has been a shift from 4th generation mobile communications (4G networks) to 5th generation mobile communications (5G networks) with a maximum speed of 20 Gbps, and unlike 4G, which uses frequencies of GHz or lower, 5G transmits data at high speeds using a wide bandwidth of hundreds of MHz or more in the high frequency bands of centimeter waves (3 GHz to 30 GHZ) and millimeter waves (30 GHz to 300 GHz).
However, when millimeter wave (mmWAVE) frequency bands of 24 GHz or higher are used in 5G, properties of a signal are similar to those of light, the signal may not avoid obstacles such as mountains or building, wavelength lengths range only from 1 to 10 mm, which narrows coverage in which base stations can transmit and receive frequencies, and there is a problem that much energy is consumed in signal transmission and reception when signals with high frequency bands are not transmitted in one direction. In addition, an existing 4G mobile communication antenna is a separate antenna separated from a transmitting and receiving device and weighs 9 to 16 kg, and since an antenna for 5G mobile communication is an integrated antenna combined with a transmitter and receiver and weighs 20 to 25 kg, when the antenna for 5G mobile communication is installed on one pole greater than 3 meters or a monopole of 2 meters or less among installation poles already installed on a rooftop or railing of a building, the antenna for 5G mobile communication should be installed at a height of 2 meters or less for safety reasons due to the weight. Accordingly, in the antenna for 5G mobile communication antenna, setting and maintaining an installation direction is more important than the antenna for the existing 4G in consideration of efficient transmission and reception of frequency signals and safety.

In addition, a shape or size of a component may be exaggerated compared to an actual component. In addition, a specific description of the related art will be omitted when deemed to unnecessarily obscure the gist of the present invention.
A configuration and operations of the antenna holding device according to the present invention will be described with reference to
An antenna holding 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 adjusting member 60.
The upper body clamp 10 and the lower body clamp 20 are coupled to a pillar or the like to fix an antenna 3. Bolts 11 and 21 capable of fastening or unfastening the body clamps 10 and 20 may be provided on the upper body clamp 10 and the lower body clamp 20, and vertical installation positions of the upper body clamp 10 and the lower body clamp 20 on the pillar 2 may be freely adjusted.
The upper antenna bracket 30 is coupled to an upper portion of a rear surface of the antenna 3, and the lower antenna bracket 40 is coupled to a lower portion of the rear surface of the antenna. The upper antenna bracket 30 may be manufactured of stainless steel (SUS) or the like. In this case, corrosion resistance is strengthened.
One side of the lower support bracket 50 is connected to the lower body clamp 20, and the other side is connected to the lower antenna bracket 40, wherein at least one side is coupled using a hinge. In
The angle adjusting member 60 includes a first fixing link 61 having one side hinge-coupled to the upper body clamp 10 and a second fixing link 62 having one side hinge-coupled to the upper antenna bracket 30, which are provided as a pair, and a first adjusting link 63 having one side coupled to the first fixing link 61 and a second adjusting link 64 having one side coupled to the second fixing link 62, which are provided as a pair. The first fixing link 61 and the second fixing link 62 are hinge-coupled to each other, and the first adjusting link 63 and the second adjusting link 64 are hinge-coupled to each other.
One side of the angle adjusting member 60 formed as described above is coupled to the upper body clamp 10, and the other side is coupled to the upper antenna bracket 30.
In the antenna holding device 1 formed as described above, the angle adjusting member 60 may be folded or unfolded to easily adjust an orientation angle of the antenna 3 and firmly and stably maintain an adjusted inclination angle. Meanwhile, an angle of the antenna 3 may be adjusted to 35° clockwise in a front view.
Meanwhile, an angle adjustment rod 65, which passes through and is coupled to a hinge-coupling portion between the first fixing link 61 and the second fixing link 62, and a hinge-coupling portion between the first adjusting link 63 and the second adjusting link 64, may be further included, and a screw thread (not shown) is formed on an outer circumferential surface of the angle adjustment rod 65 so that an angle of the angle adjusting member 60 may be adjusted by rotation or counter-rotation of the angle adjustment rod 65. That is, as the angle adjustment rod 65 is rotated clockwise or counterclockwise, the antenna faces forward or downward.
In addition, a rotary nut 65a may be provided on one end of the angle adjustment rod 65.
