Description

[Technical field]

[0001] The present invention relates to an antenna apparatus, and more particularly to an antenna apparatus equipped with an optical signal unit and a power supply unit. [Background technology]

[0002] Generally, wireless communication technologies, for example, MIMO (Multiple Input Multiple Output) technology, is a technology that dramatically increases the amount of data transmission by using multiple antennas, and is a spatial multiplexing technique in which a transmitter transmits different data through each transmitting antenna, and a receiver separates the transmitted data through appropriate signal processing.

[0003] Therefore, by simultaneously increasing the number of transmitting and receiving antennas, the channel capacity increases, making it possible to transmit more data. For example, if the number of antennas is increased to 10, the channel capacity is about 10 times that of a single antenna system using the same frequency band.

[0004] 4G LTE-advanced uses up to 8 antennas, and the current 5G stage uses base station equipment with 64 or 128 or more antennas, which is called Massive MIMO technology. While current cell operations are 2-Dimensional, Massive MIMO technology enables 3D-Beamforming, so it is also called FD-MIMO (Full Dimension MIMO).

[0005] In Massive MIMO technology, as the number of ANTs (antennas) increases, the number of transmitters and filters also increases. Nevertheless, due to the cost of leasing installation sites and spatial constraints, it is a reality to make RF components (antennas / filters / power amplifiers / transceivers, etc.) small, light, and inexpensive. Massive MIMO requires high output power to expand coverage, but the power consumption and heat generated by such high output power act as a negative factor in reducing weight and size.

[0006] In particular, when a MIMO antenna, in which modules realizing RF elements and digital elements are combined in a stacked structure, is installed in a limited space, there is a need for a compact and miniaturized design for the multiple layers that make up the MIMO antenna in order to maximize ease of installation and space utilization. There is also a strong demand for the ability to freely adjust the direction of an antenna device installed on a single support pole.

[0007] In response to the above requirement, Korean Patent Publication No. 10-2095871 (announced on April 2, 2020) (hereinafter referred to as "prior art") discloses an "antenna clamping device" equipped with a tilting unit for rotating an antenna device in the vertical direction and a rotation unit for rotating the antenna device in the horizontal direction.

[0008] However, in order to efficiently install and operate the antenna device, the antenna and RRH (Remote Radio Head), which were previously separated, are now combined into one unit called an integrated radio unit, in which various modules such as an antenna, a power supply, an optical communication module, and a filter are miniaturized and configured into one body, and the unit is installed on a pole or a wall using a fixing clamp device.

[0009] However, in the conventional antenna device, various modules are configured in one body, so when a problem occurs in one module, it is impossible to repair or replace it on-site, and the whole module must be replaced. This problem occurs because all the components and related cables included in the integrated radio unit are connected and configured in one body.

[0010] In addition, conventional antenna devices are installed with a cable slack that allows for movement within an allowable range in order to change the direction of each antenna for smooth wireless equipment, but in this case, the twisted shape of the cable represents an environmentally unfriendly state.

[0011] The existing integrated radio unit method has the advantage that service can be provided with only one body, minimizing installation space and time, and eliminating losses by eliminating the cable between the RRH and antenna. However, it has several problems.

[0012] For example, the existing one-piece body structure makes it impossible to repair each module on-site, which makes maintenance difficult and incurs excessive costs.

[0013] In addition, in conventional antenna devices, various modules such as a signal unit such as an optical communication module and a filter, and a power supply unit are provided within a single antenna housing inside the antenna device, which not only results in poor cooling efficiency of the antenna device due to heat generated by the signal unit and the power supply unit, but also results in the antenna device protruding excessively in the radial direction of the pole when the antenna device is mounted on the pole via the tilting unit and the rotation unit, causing the signal cable and power cable connected to the antenna device to be arranged in a drooping or twisted shape, resulting in an unsightly appearance.

[0014] In addition, in the conventional technology, since the signal unit and the power supply unit are arranged inside a single antenna housing, the antenna equipment must be separated when servicing the signal and power related components, which makes maintenance difficult. Summary of the Invention [Problem to be solved by the invention]

[0015] The technical objective of the present invention is to reduce the difficulty of maintenance and reduce costs by locating the modules that require the most maintenance outside the body so that only those modules can be repaired, replaced, and managed when necessary.

[0016] In addition, by arranging an externally-mounted module at the position of the installation clamp device and connecting the cables coming up from the ground via the module, the appearance of the complicatedly twisted cables can be hidden, and an environmentally friendly installation appearance can be additionally obtained.

[0017] Furthermore, by separating some of the modules, the size and weight of the integrated radio unit itself can be reduced, which reduces the load on the mounting clamp device, and this increases the resistance to external forces such as earthquakes, vibrations, and wind loads, thereby further increasing durability.

[0018] Specifically, the technical objective of the present invention is to provide an antenna device in which the internal structure of the antenna related to the signal cable and power cable connected to the outside of a conventional antenna is provided separately from the antenna, thereby improving cooling efficiency, and the signal cable and the power cable can be neatly organized on a support, and the structure related to the signal cable and the power cable can be easily maintained without having to separate the antenna.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0048] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Antenna devices according to embodiments of the present invention will now be described with reference to the drawings.

[0049] In the following description, terms related to directions such as front, back, up, down, left and right may be the same directions as the front, back, up, down, left and right shown in Fig. 1. In addition, the vertical direction may be the same direction as the up and down direction, and the horizontal direction may be the same direction as the left and right direction.

[0050] FIG. 1 is an exploded perspective view showing an antenna device according to an embodiment of the present invention, as viewed from the front side, and FIG. 2 is an exploded perspective view showing the antenna device according to the embodiment of the present invention, as viewed from the rear side.

[0051] 1 and 2, an antenna device 1 according to an embodiment of the present invention may include an antenna (an integrated radio unit (Radio Unit), 100) and an antenna installation unit (RTS; Rotation Tilt System, 200).

[0052] The antenna 100 may include a substantially hexahedral antenna housing, and a printed circuit board having at least one antenna element and at least one radio signal processor (RU) mounted thereon may be provided inside the antenna housing. Here, the antenna element may transmit and receive radio signals, and the radio signal processor may process the radio signals. The antenna housing may be made of a heat dissipating material such as aluminum, and a heat dissipating rib may be formed on the outer surface of the antenna housing to increase the contact area with the surrounding air.

[0053] The antenna installation unit 200 may be a device for installing the antenna 100 on the pole 2. The antenna installation unit 200 can install the antenna 100 on the pole 2 such that the antenna 100 is spaced a predetermined distance forward. When the antenna 100 is installed on the pole 2 via the antenna installation unit 200, the antenna installation unit 200 can also rotate the antenna 100 in the vertical and horizontal directions to adjust the direction of the antenna 100.

[0054] However, in the antenna device 1 according to an embodiment of the present invention, the internal structure of the antenna related to the signal cable and power cable connected to the outside of a conventional antenna is provided inside the photoelectric composite unit 300, and the photoelectric composite unit 300 is provided in the antenna installation unit 200 separately from the antenna 100, thereby improving cooling efficiency and providing the advantage of being able to neatly organize the signal cable and power cable on the support. Therefore, the antenna installation unit 200 does not necessarily need to have a function of adjusting the direction of the antenna 100, and it may be sufficient if it has a structure that installs the antenna 100 so that it is positioned a predetermined distance forward on the support 2.

[0055] In the conventional antenna, a power supply unit (PSU), which is most likely to cause problems after delivery, may be configured as the photoelectric composite unit 300. In addition, in the case of a small form-factor pluggable (SFP), which is most likely to cause problems, the SFP may be configured as the photoelectric composite unit 300 in consideration of the risk of loss after digital conversion, or may not be configured as the photoelectric composite unit 300 in some cases.

[0056] The support 2 may be formed of an RC bar. Of course, the support 2 is not limited to the RC bar, and may include any column-shaped member on whose outer periphery the antenna 100 is mounted via the antenna installation unit 200.

The pole fixing clamp 210 may be disposed so as to protrude in the opposite direction to the protruding direction of the antenna fixing bracket 220. For example, the antenna fixing bracket 220 may be disposed so as to protrude backward from the rear surface of the antenna 100, and the pole fixing clamp 210 may be disposed so as to protrude forward from the pole 2.

[0060] A rear portion of the pole fixing clamp 210 may be detachably fastened to the peripheral surface of the pole 2, and a rear portion of the actuator 230 may be connected to a front portion of the pole fixing clamp 210 so as to be rotatable in the horizontal direction.

[0061] The column fixing clamp 210 may be provided with a pair of column fixing clamps 210A, 210B spaced apart from each other vertically. That is, the pair of column fixing clamps 210A, 210B may include an upper column fixing clamp 210A and a lower column fixing clamp 210B. The upper column fixing clamp 210A may be spaced apart above the lower column fixing clamp 210B, and the lower column fixing clamp 210B may be spaced apart below the upper column fixing clamp 210A.

[0062] The front parts of the pillar fixing clamps 210 may be rotatably coupled to the top and bottom surfaces of the rear part of the actuator 230, respectively. That is, the rear part of the upper support fixing clamp 210A may be detachably fastened to the circumferential surface of the pillar 2, and the front part of the upper pillar fixing clamp 210A may be rotatably coupled to the top surface of the rear part of the actuator 230. Also, the rear part of the lower pillar fixing clamp 210B may be detachably fastened to the circumferential surface of the pillar 2, and the front part of the lower pillar fixing clamp 210B may be rotatably coupled to the bottom surface of the rear part of the actuator 230.

[0063] The upper column fixing clamp 210A and the lower column fixing clamp 210B may be formed to have the same structure. The front part of the upper column fixing clamp 210A may be formed in a round shape that bulges forward, and the front part of the lower column fixing clamp 210B may also be formed in a round shape that bulges forward.

[0065] The antenna fixing bracket 220 may be provided on the antenna 100. The antenna fixing bracket 220 may be provided on the rear surface of the antenna 100. The antenna fixing bracket 220 can be fixed to the rear surface of the antenna 100. The antenna fixing bracket 220 can be connected to the antenna 100 to support the antenna 100. The antenna fixing bracket 220 may be disposed to protrude toward the support pole 2 when provided on the antenna 100.

[0066] The antenna fixing bracket 220 may include an antenna fixing plate 221 and actuator coupling plates 222 and 223 .

[0067] The antenna fixing plate 221 can be coupled to the rear surface of the antenna 100. The antenna fixing plate 221 may be formed in a rectangular plate shape whose front surface contacts the rear surface of the antenna 100.

[0068] The actuator coupling plates 222, 223 may be formed to protrude backward from the rear surface of the antenna fixing plate 221. The actuator coupling plates 222, 223 may be formed to have a round shape with a bulging rear end. The actuator coupling plates 222, 223 are formed as a pair of actuator coupling plates 222, 223, and are coupled to the left and right sides of the actuator 230 so as to be rotatable in the vertical direction, respectively, and can be rotated in the vertical direction by the driving force of the actuator 230. A hole passing through in the left and right direction may be formed at the rear end of the pair of actuator coupling plates 222, 223. The hole formed at the rear end of the pair of actuator coupling plates 222, 223 so as to pass through in the left and right direction may be a hole for coupling with a rotating shaft of a reducer disposed inside the actuator 230.

[0069] The pair of actuator connecting plates 222 , 223 may include a left actuator connecting plate 222 rotatably connected to the left side of the actuator 230 , and a right actuator connecting plate 223 rotatably connected to the right side of the actuator 230 .

[0070] The actuator 230 may be substantially a single device for adjusting the vertical and horizontal directions of the antenna 100. That is, the actuator 230 may be formed by providing, in a single integrated housing, a first motor and a first reducer for adjusting the vertical direction of the antenna 100 by rotating the antenna fixing bracket 220 in the vertical direction, and a second motor and a second reducer for adjusting the horizontal direction of the antenna 100 by rotating the actuator 230 itself in the horizontal direction relative to the pole fixing clamp 210.

[0071] The actuator 230 can be coupled between the mast fixing clamp 210 and the antenna fixing bracket 220. The actuator 230 is horizontally rotatably coupled to the mast fixing clamp 210 and can rotate horizontally relative to the mast fixing clamp 210.

In addition, the rear portion of the actuator 230 is horizontally rotatably coupled to the pole fixing clamp 210, and the actuator 230 can horizontally rotate relative to the pole fixing clamp 210.

[0074] A photoelectric composite unit 300 may be disposed in the antenna installation unit 200. The photoelectric composite unit 300 is provided below the actuator 230, so that an operator can easily separate the photoelectric composite unit 300 from the actuator 230 during maintenance.

[0075] The photovoltaic composite unit 300 may satisfy the requirements for waterproofing / vibration prevention, and may be formed small in the shape of a heat sink to dissipate heat generated by a power supply unit (PSU).

[0076] In an existing integrated radio unit, the PSU and SFP parts can be separated and configured as an optoelectronic composite unit 300.

The PSU part can include a power board (320, see FIGS. 6 and 7), and the SFP part can include an optics board (330, see FIGS. 6 and 7).

[0077] A power supply board 320 may be provided inside the photovoltaic composite unit 300. In some cases, an optic board 330 may further be provided inside the photovoltaic composite unit 300. Conventionally, a power supply board and an optic board are provided inside the antenna, but in this embodiment, the photovoltaic composite unit 300 including the power supply board 320 and the optic board 330 or including only the power supply board 320 is configured separately from the antenna 10 and disposed in the antenna installation unit 200, thereby improving cooling efficiency, and signal cables and power cables that have conventionally been provided outside the antenna can be disposed close to the support pole 2 and neatly arranged on the support pole 2.

[0078] The photoelectric composite unit 300 can transmit and receive signals to and from the antenna 100, and can supply power to the antenna 100. In addition, the photoelectric composite unit 300 can supply power to the actuator 230 of the antenna installation unit 200 so that the antenna installation unit 200 can rotate the antenna 100 in the horizontal and vertical directions.

[0079] However, a substantial object of the present invention is to facilitate maintenance by separating components that require a lot of maintenance from those included in the existing antenna 100 and configuring them in the photoelectric composite unit 300, and in order to achieve this object, the antenna installation unit 200 does not necessarily include the actuator 230. Therefore, if the antenna installation unit 200 does not include the actuator 230, the photoelectric composite unit 300 can transmit and receive signals to the antenna 100 and can supply power to the antenna 100 without supplying power to the antenna installation unit 200.

[0080] The photoelectric composite unit 300 performs power supply and optical signal conversion, and can be connected to the integrated radio unit body via a cable.

The first connector 400 may be formed to protrude in a rectangular plate shape from the front surface of the antenna fixing bracket 220. The second connector 500 may be formed to protrude in a rectangular plate shape from the rear surface of the antenna 100.

[0084] Meanwhile, antenna coupling members 610 and 620 may be provided on the rear surface of the antenna 100. The antenna coupling members 610 and 620 are coupled to an antenna fixing plate 221 so that the antenna 100 can be coupled to the front surface of the antenna installation unit 200.

[0085] The antenna coupling members 610, 620 may be configured as a pair of antenna coupling members 610, 620. The pair of antenna coupling members 610, 620 may be arranged spaced apart from each other with the second connector 500 in between. In this embodiment, the pair of antenna coupling members 610, 620 is configured with a first antenna coupling member 610 arranged above the second connector 500 and a second antenna coupling member 620 arranged below the second connector 500, but the first antenna coupling member 610 may be arranged to the left of the second connector 500 and the second antenna coupling member 620 may be arranged to the right of the second connector 500.

[0086] The specific structures of the first connector 400 and the second connector 500, and the specific coupling relationship between the pair of antenna coupling members 610, 620 and the antenna fixing plate 221 will be described below with reference to FIGS.
