Description

Antenna device for base station

Technical Field

The present invention relates to an antenna device (ANTENNA APPARATUS FOR BASE STATION) for a base station, and more particularly, to an antenna device for a base station, which prevents a cable from being exposed to the outside to improve the beauty and includes a jig unit capable of realizing a beam tilting operation of an antenna module itself.

Background

In the mobile communication system, the "base station" refers to a system that relays mobile terminal radio waves in a cell. The base station is mainly installed on a roof of a building or the like to relay a portable terminal radio wave. Therefore, the base station is provided in a cell unit, and such base station controls the incoming and outgoing signal transmission, call path assignment, call path monitoring, and the like in a cell unit in addition to the interface function between the switching centers. The antenna device used by the base station is widely used because of the advantage of including a control antenna that can tilt the beam vertically or horizontally.

With the spread of mobile communication services, the distribution of antenna devices providing a wireless network environment capable of providing more stable services is expanding, and mobile communication services have been expanding from 2G (second generation) supporting only wire calls to 3G and 4G, and recently, the range of use of technologies for 5G mobile communication is expanding.

Fig. 1 is an external perspective view showing an antenna device for a base station according to the conventional embodiment.

As shown in fig. 1, the base station antenna device according to the conventional embodiment is installed outdoors (outdoors), the antenna module 10 is mounted on the upright pole 11 via the fixing brackets 30 and 31, the repeater 12 is mounted on the lower side of the antenna module 10 via the fixing brackets 32 and 33, and the plurality of cables 14 are electrically connected between the antenna module 10 and the repeater 12. The fixing brackets 30 and 31 are respectively disposed at the upper and lower ends of the antenna module 10 and fixed to the pole 11, and are respectively disposed at the upper and lower ends of the repeater 12 and fixed to the pole 11. The fixing brackets 30 to 33 are fixed with fasteners such as screws, bolts, nuts, or the like.

However, the conventional antenna device for a base station has a limited structure in which the pole 11 is disposed outdoors (outdoors) as a medium, and has a structure in which the antenna module 10 is mounted on the opposite upper side of the pole 11 and the repeater 12 is mounted on the opposite lower side, for example, after the radio remote head (RHH) is mounted, the connection is performed by the cable 14, and thus the cable 14 is exposed to the outside, which deteriorates the beauty.

Although not shown in the drawings, in particular, when the repeater 12 and the antenna module 10 are separated, and an electrical connection structure using the cable 14 is provided, the above-described problem occurs similarly in the case of being installed indoors (i.e., in a building), and in the case of being installed in a building, it is more necessary to prevent the aesthetic deterioration.

Recently, although not shown, in order to solve the problem of the deterioration of the beauty, an antenna module is coupled to the front of the repeater, and the repeater and the antenna module are electrically connected by a socket pin coupling or the like instead of a cable coupling.

However, in this case, the repeater should also adopt a tilt structure together in order to tilt the beam of the antenna module, and thus, as a large tilt space is occupied, there is a problem in that space lease costs may increase.

Meanwhile, recently, an antenna device for a base station provided in an outdoor or indoor sidewalk where a portable terminal user often moves is compactly formed so as to occupy a small space and is designed in consideration of factors minimizing a reduction in beauty.

As shown in fig. 2 to 6, the base station antenna device 100 according to an embodiment of the present invention includes a repeater 120 and an antenna module 110 provided at a predetermined location. The predetermined location where the base station antenna device 100 according to an embodiment of the present invention is installed is limited to the indoor and outdoor walls or ceilings of a building, and at least the configuration described later may be such that the repeater 120 is shaped to fit inside the building.

The antenna module 110 may refer to an antenna module having at least one frequency band. The repeater 120 is connected to an antenna for each frequency band provided to the antenna module 110 as a remote radio head (RRH, remote Radio Head) and transmits and receives signals between the antenna and the base station.

The repeater 120 is a repeater device that receives and amplifies or retransmits a weakened signal or reshapes a distorted waveform between a base station of a mobile communication system and a mobile communication terminal and readjust timing and the like.

Although not shown in the drawings, in the base station antenna device 100 according to an embodiment of the present invention, the repeater 120 is usually mounted on the indoor or outdoor wall surface of a building, and the antenna holder unit 200 described later is used as a medium, so that the antenna module 110 can be mounted on the front surface of the repeater 120 in a tilting and steering manner.

However, as shown in fig. 2 to 6, the embodiments of the present invention are not necessarily installed on the wall surface of the room, but may be installed on the ceiling of the room (house) as shown in fig. 8 a. In this regard, the following will explain in detail.

As shown in fig. 4, the antenna module 110 covers the antenna housing 111 and the front surface of the antenna housing 111, and may include a radome 113 forming a prescribed space between the antenna housing 111 and the radome.

An antenna board 115 in the form of a printed circuit board may be provided in a predetermined space of the antenna housing 111, and a plurality of radiation devices may be mounted on the front surface of the antenna board 115. The radiation device mounted and arranged on the antenna board 115 may be different depending on the kind of antenna, and in an embodiment of the present invention, a dipole device 117 (dipole device) is described. However, the radiation device is not necessarily constituted by a dipole device, and may be constituted by a patch type patch device.

On the other hand, as shown in fig. 2 to 6, the antenna device 100 for a base station according to an embodiment of the present invention may further include an antenna jig unit 200 that plays a role of a medium for coupling to the front surface of the repeater 120.

In more detail, as shown in fig. 2 to 6, the repeater 120 includes: a panel part 121 provided to be closely attached to a wall surface of the room; and a cover 123 provided in front of the installation panel 121, and having a predetermined space formed therebetween, in which a plurality of internal components can be installed.

Although not shown, the internal structural components provided inside the repeater 120 may include a main board (main board), two power amplifying sections (PAU: power Amplifying Unit), and a power supplying section (PSU: power Supplying Unit).

In the repeater 120, the plurality of fins 125 are integrally formed on the front surface of the cover 123, and the system heat generated in a predetermined space can be released to the outside through the plurality of fins 125.

On the other hand, a plurality of heat radiating fins 125 may be partially removed to form a rectangular surface-shaped installation groove 127 on the front surface of the housing 123, and the antenna jig unit 200 is coupled to the installation groove 127 by a plurality of assembly screws 215. However, the front surface of the cover 123 is not necessarily provided with the installation groove 127 removed in a quadrangular plane shape in order to install the antenna jig unit 200, and may be formed in a circular shape or any other coupling end shape corresponding to the end shape of each connection portion of the antenna jig unit 200 as shown in other embodiment 100' referred to in fig. 9 described later.

Wherein, the antenna jig unit 200 may include: a fixing portion 210 having a cylindrical shape that is opened in the front-rear direction; and a moving part 220 having a rear end inserted in front of the opening of the fixed part 210 and coupled to the antenna module 110 at a front end.

The rear end portion of the moving portion 220 accommodated in the fixing portion 210 has a substantially hemispherical shape with a rear opening, and is locked by the front end portion of the fixing portion 210, thereby preventing detachment to the outside (particularly, the front).

The front and rear sides of the moving part 220 are opened and communicate with the inner space of the fixed part 210, and a cable C for electrically connecting the repeater 120 and the antenna module 110 may be provided in the communicating inner space of the fixed part 210 and the moving part 220.

The cable C is in a wire form having a length at least longer than a linear distance between a front end connection position of the repeater 120 and a rear end connection position of the antenna module 110, so that the antenna module 110 can perform tilting and steering operations described later, and an excessive length portion of the cable C is stored in an inner space of the fixing portion 210 in a state of preventing twisting. Therefore, the cable C is provided so as to be hidden from the outside, and the reduction of the appearance can be prevented.

The moving part 220 can perform tilting and steering operations so that a predetermined angle can be maintained with respect to the fixed part 210 in a square including up-down or left-right directions. Here, the term "tilting operation" is a concept including all operations in which the upper and lower ends of the antenna module 110 are swung in the front-rear direction, and the term "steering operation" is a concept including all operations in which the left and right ends of the antenna module 110 are swung in the left-right direction.

In the base station antenna device 100 according to the embodiment of the present invention, the moving unit 220 may perform the tilting operation and the steering operation at the same time, instead of performing only one of the tilting operation and the steering operation of the antenna module 110.

More specifically, the front end of the moving portion 220 can be tilted and steered by a predetermined angle in a four-way direction including the up-down or left-right direction around an arbitrary reference point of the rear end portion housed in the fixed portion 210.

As the front end of the moving part 220 performs tilting and steering, the antenna module 110 coupled to the front end may also perform tilting and steering, and the direction of the antenna module 110 may be adjusted in a direction required by a designer.

The moving portion 220 can perform tilting and steering operations in a state having a certain degree of friction with the fixed portion 210. For this purpose, friction pads (or friction members) that form a predetermined friction force with each other may be provided on the inner surface of the fixed portion 210 or the outer surface of the rear end portion of the movable portion 220.

However, the means for providing friction between the movable portion 220 and the fixed portion 210 is not limited to the friction pad described above. That is, as shown in fig. 5, a gasket groove 218 is formed inside the distal end portion of the fixed portion 210, and a gasket 219 made of an elastic material (for example, a rubber material) is formed in the gasket groove 218, so that a friction force can be formed between the movable portion 220 and the fixed portion 210. The gasket 219 formed at the gasket groove 218 forms a frictional force between the moving part 220 and the fixed part 210, thereby enabling fine adjustment when the moving part 220 performs tilting or steering operation, and simultaneously, performing a waterproof function of preventing inflow of external foreign matters including rainwater or the like.

On the other hand, although not shown in the drawings, the antenna jig unit 200 may further include a moving locking portion that fixes the moving portion 220 to the fixing portion 210 at a moving fixing point after the moving portion 220 is tilted and turned by a prescribed angle with respect to the fixing portion 210.

Any means may be used as long as the movable portion 220 is fixed to the fixed portion 210, and the movable locking portion may be realized by, for example, a fixing bolt penetrating through the outside of the fixed portion 210 accommodating the rear end portion of the movable portion 220 to interfere with a part of the movable portion 220. The fixing bolt is a headless bolt (a bolt without a head), and thus can be prevented from protruding to the outside of the fixing portion 210.

As described above, according to the antenna device 100 for a base station according to an embodiment of the present invention, the antenna clamp unit 200 prevents the aesthetic deterioration by suppressing the exposure of the outside of the cable C connecting between the repeater 120 and the antenna module 110, and also allows only the antenna module 110 to perform tilting and steering operations and prevents the repeater 120 from performing tilting and steering operations, thereby maximizing the space utility.

As shown in fig. 7a to 7c, in the base station antenna device 100 according to the first embodiment of the present invention, the antenna modules 110 are the same configuration to which the dipole (or patch antenna device) is commonly applied, and only the configuration of the repeater 120 is different.

In more detail, the repeater 120 described with reference to fig. 7a to 7c may have a shape in which the width in the left-right direction is relatively small and the length in the up-down direction is relatively large, as compared with the repeater 120 described with reference to fig. 2 to 6. In this case, it is preferable that the set position of the antenna module 110 be set in place in consideration of the weight and the tilting and steering operations of the antenna module 110.

In particular, in the case of the repeater 120 described with reference to fig. 7a to 7c, it is possible to provide an advantage of providing 2 or more antenna modules 110 up and down for a length in the up-down direction to be relatively large.

As shown in fig. 8a to 8d, the base station antenna device 100 according to the second embodiment of the present invention may be provided on the indoor wall surface described with reference to fig. 2 to 7c, or may be provided on a structure (e.g., ceiling finishing material) such as a ceiling surface in or out of a building.

In this case, as shown in fig. 8a to 8d, the repeater 120 is disposed so as to extend in the left-right direction (horizontal direction), and one of the width end portions of the repeater 120 may be fixed to the lower surface of the ceiling finishing material forming the ceiling with the ceiling setting bracket 150C as a medium, and then the antenna module 110 may be set on the front surface side of the repeater 120 as described above.

However, the repeater 120 is not limited to being disposed so as to extend in the left-right direction, and may be disposed so as to extend in the up-down direction according to the embodiment.

As described later in the fourth and fifth embodiments, in the embodiment in which the repeater 120 is buried in the ceiling finishing material forming the ceiling, as shown in fig. 11, the repeater 120 may be disposed in close contact with a portion corresponding to the installation panel portion 121 on the inner surface (upper surface) of the ceiling finishing material. This will be described in detail below.

Fig. 9 is a perspective view showing the appearance of a base station antenna device according to a third embodiment of the present invention provided on a wall surface of an indoor or outdoor building, and fig. 10 is an exploded perspective view of fig. 9.

The base station antenna device 100 according to the first embodiment of the present invention described above with reference to fig. 2 to 7c is realized by an embodiment in which a single antenna module 110 is provided for one repeater 120.

However, as shown in the first embodiment of the present invention, the present invention is not limited to the embodiment in which only a single antenna module 110 is provided in one repeater 120, and as shown in fig. 9 and 10, 2 or more (i.e., a plurality of) antenna modules may be provided in one repeater 120 (see reference numerals "110A and 110B" in fig. 9 and 10).

This means that, in the antenna clip unit 200, when the number of the repeaters 120 is 2 or more, the number of the extension portions 230, the fixed portions 210, and the moving portions 220 may correspond to the number of the repeaters 120.

When 2 antenna modules 110A and 110B are provided in one repeater 120, a main board (main board) corresponding to the number of antenna modules, two power amplifying units (PAU: power Amplifying Unit), and a power supplying unit (PSU: power Supplying Unit) are provided in the one repeater 120 so as to perform independent transmission/reception functions based on the antenna modules 110A and 110B. s

Meanwhile, the number of antenna jig units 200 also corresponds to the number of antenna modules 110A, 110B (refer to reference numerals "200A, 200B" of fig. 9 and 10). This is quite different from the number of the relays 120 of the antenna clip unit 200.

However, in the base station antenna device 100 according to the first embodiment of the present invention described with reference to fig. 2 to 7c, the rear end portion of the opening of the fixing portion 210 is directly provided on the front surface of the cover portion 123 of the repeater 120, whereas in the base station antenna device 100 'according to the third embodiment of the present invention described with reference to fig. 9 and 10, the antenna jig units 200A and 200B may further include extension portions 230 arranged in parallel so that the fixing portion 210 is spaced apart from the front surface of the cover portion 123 of the repeater 120, and may be provided so as to extend so as to be connected to the front end on the opening side of the fixing portion 210 and to the repeater-side coupling end 127' formed on the front surface of the cover portion 123.

Here, an annular fastening end 229 may be provided at the open front end of the moving part 220, and the fastening end 229 of the moving part 220 may be firmly fastened to the antenna-side coupling end 119 provided at the rear surface of the antenna modules 110A, 110B by a fastening screw (not shown) or the like.

The repeater 120 can be easily attached to the indoor or outdoor wall surface W with the fastening members 129 such as a plurality of bolts fastened thereto as a medium, which are provided with the brackets 150W.

As described above, according to the antenna device 100' for a base station of the third embodiment of the present invention, there is an advantage in that the direction of the plurality of antenna modules 110A, 110B can be adjusted in one repeater 120 so as to achieve beam tilting and steering in a desired direction, and in addition, the antenna device can be compact and suppress the exposure of the cable C to the maximum extent to prevent the reduction of the beauty.

Fig. 11 is a downward perspective view (a) and an upward perspective view (b) of a base station antenna device according to a fourth embodiment of the present invention as a modification of fig. 8a to 8d, and fig. 12 is a partially cut-away perspective view of the portion (a) of fig. 11.

As shown in a second embodiment 100 of the present invention described with reference to fig. 8a to 8d, the antenna device 100' for a base station according to the fourth embodiment of the present invention may be provided on a ceiling of an indoor (house) or an outdoor ceiling-like structure, and in addition, at least a repeater may be buried in a ceiling-corresponding structure (for example, ceiling finishing material) in order to improve the appearance.

In more detail, referring to fig. 11 and 12, the repeater 120 is placed on the inner surface (upper surface) of the ceiling finishing material, which is a structure corresponding to the ceiling, with the installation bracket 150C as a medium so as to be closely attached to the portion corresponding to the installation panel portion 121, and the plurality of antenna modules 110A, 110B may be installed so that electrical connection by the cable C can be achieved at the installation panel portion 121 of the repeater 120 by the extension portion 230 of the moving portion 220.

In this case, it is preferable that a penetrating portion H is provided in the ceiling finishing material as a structure corresponding to the ceiling, and a portion corresponding to each of the extending portions 230 of the antenna jig units 200A, 200B is formed to penetrate up and down so as to penetrate the connection cable C.

As described above, the antenna device 100' for a base station according to the fourth embodiment of the present invention has an advantage in that at least the repeater 120 is buried inside a structure such as a ceiling, and thus, the cable C is further suppressed from being exposed to the outside and the repeater 120 is suppressed from being exposed to the outside, whereby deterioration in the aesthetic appearance can be prevented to the greatest extent. In this case, the antenna modules 110A and 110B are exposed to the outside, and the direction adjustment by the tilting operation and the steering operation is not different from the base station antenna device 100 according to the first and second embodiments of the present invention.

In the above-described base station antenna devices 100 and 100' according to the first to fourth embodiments of the present invention, the explanation has been made on the premise that one antenna module 110, 110A, 110B is provided in each of the antenna jig units 200, 200A, 200B, but it is not necessary to provide one antenna module 110 in each of the antenna jig units 200, and as shown in fig. 13a and 13B, a plurality of antenna modules 110A to 110C may be provided in each of the antenna jig units 200.

That is, in the antenna jig unit 200, when the number of the repeaters 120 is 2 or more, the number of the extension portions 230 is one, and the number of the fixed portions 210 and the moving portions 220 may correspond to the number of the repeaters 120.
