Description

[0001] LIGHTWEIGHT ANTENNA ASSEMBLY AND SUPPORT FOR AN ANTENNA ASSEMBLY [0002]

The present invention relates to a lightweight antenna assembly and a support for the antenna assembly.

An antenna is a device that transmits and receives electromagnetic waves. In general, a directional antenna installed in a base station is directly exposed to the outside, so that the antenna assembly requires a radome to protect its internal components from external environments such as wind, rain, and the like.

The term radome is a combination of a radar and a dome, and refers to an outer cover that protects an apparatus such as an antenna. As can be deduced from the name, the radome may be implemented as a dome, but it is implemented in various shapes depending on the configuration and size of the antenna.

For example, FIG. 1 is a view showing an antenna assembly and its installation structure installed in a base station in general. As shown in FIG. 1, the antenna assembly 1000 may be installed in the antenna mounting structure 1010 via connecting members 1020 and 1030.

An antenna for a base station is generally installed in a high zone on the nature and in an open area without an obstacle in the vicinity thereof, in order to prevent the transmission radio wave of the antenna from being blocked. However, the higher the elevation, the greater the influence of the wind, and the radome of the antenna assembly must be designed to withstand greater wind pressure.

If the effect of the wind is large, it may happen that the radome can not cope with wind pressure. For example, if the wind pressure is excessively high, the radome may be pressurized and deformed by winds, touching components such as radiators housed within the radome, and even causing damage.

One way in which the antenna assembly can withstand higher wind pressure is to increase the thickness of the radome. However, increasing the thickness of the radome increases the overall weight of the antenna assembly. Basically, an increase in weight in a large-scale antenna assembly can make it difficult to install the antenna assembly, thus increasing the installation cost.

There is therefore a need for an antenna assembly that is able to withstand high wind pressure while keeping overall weight low.

An aspect of the present invention is to provide an antenna assembly and a support for an antenna assembly that can tolerate high wind pressure while keeping the overall weight low.

According to an aspect of the present invention, A radiator arranged on one surface of the reflection plate; A support disposed on one surface of the reflection plate; And a radome for receiving the reflector, the radiator and the support, wherein the support includes a support portion for applying a resistance force to the inner surface of the radome when a predetermined external pressure is applied to the radome, and a coupling portion coupled to the reflection plate An antenna assembly is provided.

The distance between the support and the inner surface of the radome may be configured to be less than the distance between the radiator and the inner surface of the radome.

The reflection plate may include a flat flat portion and a side bent portion bent in the direction of the one surface from the flat portion, and the coupling portion may be coupled to be in contact with the side bent portion.

When the reflection plate includes the side bending portion, the coupling portion may include a slit formed in a direction in which the side bending portion is bent, and the side bending portion is inserted into the slit so that the support can be coupled to the reflection plate.

A slit may be formed in the reflector, and the width of the support may increase from the upper side to the lower side. As a result, the support can be coupled to the reflector as it is inserted through the slit from the lower side to the upper side of the reflector.

The reflector may include an alignment groove formed in a shape corresponding to the engaging portion.

When the reflector is inserted into the radome by sliding, a groove or protrusion extending along the sliding direction of the reflector may be formed on the inner surface of the radome at a position corresponding to at least one of the reflector and the support, Protrusions or grooves engaging with the grooves or protrusions may be formed.

The antenna assembly according to an embodiment of the present invention may further include a base portion disposed on the other surface of the reflection plate to support the reflection plate.

When the base portion is included, the engaging portion and the base portion may be coupled to each other by fastening means passing through the reflector.

When the reflector is inserted into the radome by sliding, a groove or a protrusion extending along the sliding direction of the reflector may be formed on the inner surface of the radome at a position corresponding to the base, Or grooves may be formed.

An antenna assembly according to an embodiment of the present invention may include a plurality of supports, which are disposed on the reflector at predetermined intervals, wherein a plurality of supports are arranged at a smaller interval in the middle portion in the longitudinal direction of the reflector .

Further, the antenna assembly according to an embodiment of the present invention may include a plurality of supports. In this case, the antenna assembly may further include a reinforcing member connecting the two or more supports to each other.

The antenna assembly according to an embodiment of the present invention may also include a plurality of reflection plates, and the support may include a plurality of coupling portions, and the plurality of coupling portions may be coupled to different reflection plates, respectively.

The support portion may be formed in a shape corresponding to the inner surface of the radome.

According to another aspect of the present invention, there is provided a support for use in an antenna assembly including a reflector, a radiator, and a radome, comprising: a support for applying a resistance force to the inner surface of the radome when a predetermined external pressure is applied to the radome; A leg extending from the support such that the distance between the support and the inner surface of the radome is less than the distance between the radiator and the inner surface of the radome; And a coupling portion formed on the leg portion and coupled to the reflection plate.

According to some embodiments of the invention, the antenna assembly can tolerate high wind pressure while keeping the overall weight low. It is possible to maintain the low weight while providing the required strength, so that the antenna assembly can be installed more easily and at low cost.

While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and will herein be described in detail. It should be understood, however, that the invention is not intended to be limited to the particular embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention. Like reference numerals are used for like elements in describing each drawing.

The terms first, second, etc. may be used to describe various components, but the components should not be limited by the terms. The terms are used only for the purpose of distinguishing one component from another. For example, without departing from the scope of the present invention, the first component may be referred to as a second component, and similarly, the second component may also be referred to as a first component. Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

2 is a perspective view illustrating an antenna assembly according to an embodiment of the present invention. The antenna assembly 1000 may have an internal structure, for example, as shown in any of Figs. 4 to 9, and may have an external structure as shown in Fig.

The antenna assembly 1000 may be a directional antenna installed in a base station and may include a reflector 100, one or more radiators 200, and a phase shifter (not shown), as shown in FIG.

The reflector 100 may serve as a reflector and a ground as a conductor, and may have a bent shape, for example, as shown in FIG. Of course, the reflection plate 100 may have a flat shape instead of a bent shape.

The radiator 200 is a device for outputting a predetermined radiation pattern and may be sequentially arranged on one surface of the reflection plate 100 as shown in FIG.

Although not shown, the phase shifter may be formed on the other surface of the reflection plate 100, that is, on the surface opposite to the surface on which the radiators 200 are arranged. The phase shifter may control the phase of an input signal input from the outside And distribute the power to the radiators 200. [

2, the antenna assembly 1000 may also include a radome 400, an end cover 450, and connector portions 451 and 452. [

The radome 400 may accommodate internal components such as a reflector 100, a radiator 200, a phase shifter, and the like. After inserting the components into the radome 400 extending along one direction, the end cover 450 may be mounted to protect the internal components from the external environment.

The end cover 450 may have connector portions 451 and 452 formed thereon. The connector portions 451 and 452 may serve to connect the inside and the outside of the antenna assembly 1000. For example, a feed signal and other control signals to be applied to the phase shifter and the radiator may be provided through the connector portions 451 and 452.

The radome 400 is formed of a non-conductive material so as not to interfere with the electromagnetic wave transmission / reception of the radiator 200. It may be advantageous for the radome 400 to use materials that provide less weight and higher strength, such as, for example, fiber-reinforced plastic (FRP).

As described above, increasing the thickness of the radome 400 to provide the strength to withstand high wind pressure can increase the overall weight of the antenna assembly 1000, increasing the effort and cost required for installation. In contrast, in an embodiment of the present invention, a member for structurally reinforcing the radome 400 is used so as to protect the internal components without increasing the thickness of the radome 400.

3 is a perspective view illustrating a support for an antenna assembly according to an embodiment of the present invention. Referring to FIG. 3, the support 300 may include a support portion 340, a leg portion 350, and a coupling portion 360.

The support 300 may be made of a non-conductive material such as plastic. If the support 300 is made of a conductive material, it may affect the radiation properties of the radiator 200, and a separate measure may be required.

The support portion 340 may be configured to contact the inner surface of the radome 400 to apply a resistance force when a predetermined external pressure is applied to the radome 400. [ The leg portion 350 may extend from the support portion 340 such that the support portion 340 is positioned at a predetermined position with respect to the reflection plate 100. The coupling portion 360 may serve to couple the support 300 to the reflection plate 100.

When the support 300 is coupled to the reflector 100 as described above, even if the radome 400 is pushed inward by the wind pressure, the support portion 340 of the support 300 provides resistance against wind pressure, Other internal components can be prevented from being touched or damaged.

It may be advantageous that the support portion 340 is located closer to the inner surface of the radome 400 than the radiator 200 to prevent the inner surface of the radome 400 from contacting the radiator 200 even if wind pressure is applied. The height and width of the support portion 340 can be determined such that the distance between the support portion 340 and the inner surface of the radome 400 is less than the distance between the radiator 200 and the inner surface of the radome 400. [

The supporting portion 340 applies a resistance force when a predetermined external pressure is applied to the radome 400, so that the supporting portion 340 does not normally have to contact the radome 400. That is, the support portion 340 is formed to have a height and width that does not allow the inner surface of the radome 400 to touch the radiator 200 when a predetermined wind pressure is applied to the radome 400 and the radome 400 is pushed inward and deformed And when the wind pressure is not applied to the radome 400, the support portion 340 may not be in contact with the inner surface of the radome 400.

Of course, it is also possible to prevent buckling of the radome 400 and maintain the original shape of the radome 400, even if the support portion 340 contacts the radome 400 and high wind pressure is applied.

If the contact area between the support portion 340 and the inner surface of the radome 400 is excessively small when the wind pressure is applied, the support portion 340 exerts a concentrated shearing force to one point of the radome 400, thereby tearing the radome 400 have. Therefore, in one embodiment of the present invention, the support portion 340 may be formed in a shape corresponding to the inner surface of the radome 400 as shown in FIG. 3, so that the upper portion is relatively wider and flat.

The support portion 340 has a shape corresponding to the inner surface of the radome 400. The support portion 340 has a shape corresponding to the inner surface of the radome 400 as well as the inner surface of the support portion 340 and the inner surface of the radome 400, The support portion 340 does not exert an excessive shearing force when the wind pressure acts on the radome 400 as shown in FIG.

The leg portion 350 may extend from the support portion 340 such that the support portion 340 extends from the support portion 340 such that the support portion 340 is located at a predetermined position with respect to the reflector 100, for example, higher than the radiators 200 . That is, the leg portion 350 may extend downward to connect the support portion 340 and the reflection plate 100 and to transmit an external force applied to the support portion 340. However, it is not necessary to include two leg portions 350 extending downward from both ends of the support portion 340 as shown in FIG. 3, but various shapes and configurations for positioning the support portion 340 at a required height Can be used.

The engaging portion 360 refers to a portion coupled to the reflector 100. The coupling portion 360 may be formed on the leg portion 350 and the external force applied to the support portion 340 may be transmitted to the reflection plate 100 through the leg portion 350 and the coupling portion 360. [

In an embodiment of the present invention, the engaging portion 360 may be configured to be relatively wider and flat as shown in Fig. This allows the support 300 to stand more stably on the reflector 100 and to be more firmly coupled.

The engaging portion 360 may be attached to the reflecting plate 100 by an adhesive or the like by a fastening means such as a bolt or the like, And a projection or the like may be provided and may be engaged by fitting. Of course, the coupling portion 360 can be implemented in various forms, and various coupling methods can be used. Also, the engaging portion 360 does not necessarily have to be coupled to any one surface of the reflector 100. [ For example, a part of the support 300 may be coupled to a lower surface of the reflection plate 100 through a hole or the like formed in the reflection plate 100. [

FIG. 3 shows an example in which leg portions 350 are formed at both ends of the support portion 340 and coupling portions 360 are formed in the respective leg portions 350, but the present invention is not limited thereto. In FIG. 3, the spacing between the lower portion of the support portion 340 and the reflector is for reducing the use of materials. In other embodiments, the trapezoidal support 300 may be used without such a gap.

As such, in some embodiments, the distinction between the support portion 340, the leg portion 350, and the coupling portion 360 of the support 300 may not be as clear as in FIG. For example, when the support 300 is embodied as only one rectangular member, the portion of the support 300 that contacts the reflection plate 100 is the engagement portion 360, and when the external pressure is applied, The portion contacting the inner surface is the support portion 340, and the portion between the supports is the leg portion 350. [

FIG. 4 is a perspective view illustrating an attachment state of a support in an antenna assembly according to an embodiment of the present invention. FIG. In FIG. 4, the radome 400 is omitted to facilitate understanding of the present embodiment.

The support 300 may be disposed at a predetermined position of the reflector 100 and the support 300 may include two radiators 200 when the antenna assembly 1000 includes only one reflector 100. [ As shown in FIG. The support portion 340 of the support 300 may be formed to have a height and a width that are positioned closer to the inner surface of the radome 400 than the radiator 300. [

When the reflector 100 is folded to include the planar portion 120 and the side curved portion 140, the engaging portion 360 of the support 300 contacts the side curved portion 140, 100).

Since the support 300 contacts the side bending portion 140, the side bending portion 140 can reinforce the support 300 on both sides. In addition to reinforcing the force in the lateral direction of the support 300, when the leg 300 of the support 300 has a width increasing from the upper side to the lower side as shown in FIGS. 3 and 4, It is possible to reinforce the force even in the vertical direction in the structure of FIG. The side bends 140 may also assist and support the support 300 on both sides to help maintain the support 300 in a defined position. This is particularly the case when the engaging portion 360 is engaged not only with the plane portion 120 but also with the side bending portion 140.

FIG. 5 is a view showing a mounting state of a support in an antenna assembly according to another embodiment of the present invention. FIG. 5A is a perspective view showing a state before the support 300 is coupled to the reflection plate 100 and FIG. 5B is a sectional view showing a state after the support 300 is coupled to the reflection plate 100 . In FIG. 5, the radome 400 is omitted to facilitate understanding of the present embodiment.

Referring to FIG. 5, in the antenna assembly 1000 according to another embodiment of the present invention, the reflection plate 100 may include a planar portion 120 and a side bent portion 140, And a coupling slit 370 formed in the portion 360 in a direction in which the side bent portion 140 is bent.

Each slit 370 of the support 300 may be formed in a size and position corresponding to the side bending portion 140. 5, the distance between the two slits 370 is formed to be equal to the distance between the two side bends 140 in the reflector 100. In this case, .

The supporting body 300 can be mounted such that the side bent portion 140 is inserted into the slit 370 when the supporting body 300 is coupled to the reflecting plate 100. As a result, .

5 shows an example in which the slit 370 for coupling is formed only at the engaging portion 360 of the support 300. The slit may be formed in the side bent portion 140 of the reflector 100, And may be formed on both the side bending portion 140 and the engaging portion 360.

5, an alignment groove 130 may be formed in the reflection plate 100. Referring to FIG. The alignment groove 130 is a groove formed in a shape corresponding to a portion where the engagement portion 360 of the support 300 contacts the reflection plate 100. A part of the engaging part 360 of the supporting body 300 is inserted into the alignment groove 130 so that the supporting body 300 can be arranged more stably.

In the example of FIG. 5, the lower portion of the engaging portion 360 is configured to be wide and flat so that the supporting body 300 is more firmly and stably engaged. This will be referred to as a seating portion 365. The alignment groove 130 may be formed on the flat surface portion 120 of the reflection plate 100 with the same dimensions as the seating portion 365. When the support 300 is coupled to the reflection plate 100, And can be inserted into the groove 130 to align and fix the supporting body 300.

As another example of the alignment groove 130 formed in the shape corresponding to the engagement portion 360, the alignment groove 130 may be formed to have the same thickness as that of the engagement portion 360 to cross the other side of the reflection plate 100 Home. The reflector 100 and the alignment grooves 130 can be processed more easily if the alignment grooves 130 are crossed from one side of the reflection plate 100 to the other side.

If necessary, in addition to the engaging slit 370 formed in the engaging portion 360, other engaging means may additionally be used, and such engaging means may be applied in the aligning recess 130. [

FIG. 6 is a perspective view showing a mounting state of a support in an antenna assembly according to another embodiment of the present invention. FIG. It is only in FIG. 6 that the support 300 is positioned near the edge of the reflector 100 to effectively show the structure of the support 300, and in practical application of the embodiment of the present invention, As will be understood by those skilled in the art.

Referring to FIG. 6, the support 300 may be formed to have a width increasing from the upper side to the lower side. For example, the leg portions 350 at both ends of the support portion 340 may extend so as to spread along the lower direction. On the other hand, a fixing slit 135 for the support 300 may be formed on the reflection plate 100. The length of the slit 135 is longer than the smallest width of the support 300 and shorter than the largest width of the support 300.

In this case, the support 300 can be coupled to the reflection plate 100 by inserting the support 300 through the slit 135 from the lower side of the reflection plate 100 to the upper side. A narrow portion of the support body 300 is inserted first and passes through the slit 135. At the point where the width of the support body 300 and the length of the slit 135 become equal to each other, ).

Although not shown, a predetermined groove may be formed in the coupling portion of the supporting body 300 so that the supporting body 300 is fixed at a right angle to the reflection plate 100, and an elasticity for fixing the supporting body 300 in the correct position A latching piece or the like may be formed.

2, the antenna assembly 1000 may be formed by sliding the reflector 100 from one end of the antenna assembly 1000 to the other end thereof, May be inserted into the radome 400. [0033] FIG.

A groove or a protrusion 480 extending along the sliding direction may be formed on the inner surface of the radome 400 at a position corresponding to the reflection plate 100 or the support 300 and the reflection plate 100 or the support 300 300 may be formed with protrusions (not shown) to be engaged with corresponding grooves (not shown) or grooves to be engaged with corresponding protrusions 480.

According to an embodiment of the present invention, the coupling portion 360 of the support 300 and the base portion 500 can be coupled to each other. That is, a predetermined fastening means 505 passing through the reflection plate 100 may be used to join the coupling portion 360 and the base portion 500 together.

In the example of Fig. 7, bolts are shown as an example of the fastening means 505. Fig. If a bolt is used, a female thread corresponding to the bolt may be machined on the engaging portion 360 and the base portion 500. It should be understood that the fastening means 505 need not necessarily be a separate and independent member and that the fastening means 505 may be part of the fastening portion 360 extending toward the base 500, And may be a part of the unit 500. In this case, a predetermined hole may be formed at a corresponding position in the reflection plate 100. The fastening means 505 is not limited to any specific shape or shape, and various joining methods can be applied.

The base portion 500 may be formed to extend along the length of the reflection plate 100, or may have a shorter length, and may be disposed at predetermined intervals. When a plurality of base portions 500 are disposed on one side of the reflection plate 100, there may be a base portion 500 that is not coupled to the support body 300.

As described above, when the antenna assembly 1000 is extended in one direction and the inner components are inserted into the radome 400 by sliding from one end toward the other end, the inner surface of the radome 400 is provided with a A protrusion 480 extending along the sliding direction may be formed on the protrusion 480 and a projection (not shown) or a protrusion 480 engaged with the protrusion 480 corresponding to the groove (not shown) A corresponding engaging groove 580 can be formed.

FIG. 8 is a perspective view showing a mounting state of a support in an antenna assembly according to another embodiment of the present invention. FIG. In FIG. 8, the radiators 200 and the radome 400 are omitted, but only the installation position 205 of the radiators 200 is shown to facilitate understanding of the embodiment.

As shown in FIG. 8, the antenna assembly 1000 according to an embodiment of the present invention may include two or more reflectors 101 and 102.

When the support 300 has two or more legs 350 or engaging portions 360, the engaging portions 360 of one support 300 may be coupled to the different reflectors 101 and 102, respectively.

Further, the antenna assembly 1000 may include two or more supports 300, and may be disposed on the reflectors 101 and 102 at predetermined positions or at predetermined intervals. For example, in consideration of the shape of the antenna assembly 1000 and the radome 400, the supports 300 may be disposed at a portion vulnerable to external pressure or other necessary position.

8, the radome 400 is bent or bent at both sides corresponding to the left side of the first reflector 101 and the right side of the second reflector 102, and the first reflector 101 and the second reflector The radome 400 can be sufficiently reinforced by supporting only the center portion of the radome 400 if the support members 300 having a flat shape at the middle portion against the portion where the second reflector 102 meets.

When only one reflector 100 is used, each support 300 may be disposed at a location between the radiators 200. [ The support 300 may be disposed at a position other than the position between the radiators 200 depending on the dimensions of the radiator 200 and the support 300 when two or more reflectors 101 and 102 are used.

Referring to FIG. 8, the supports 301 to 305 may be disposed at predetermined intervals between the mounting positions 205 of the radiators. In Fig. 8, the supports 301, 302, 304 and 305 are arranged at equal intervals. Assuming that both ends of the radome 400 are equipped with the end cover 450 and the left and right portions are bent or bent, the central portion of the radome 400 may be most vulnerable to external pressure. Therefore, in one embodiment of the present invention, in addition to the support members 301, 302, 304, 305 disposed at predetermined intervals, an additional support member 303 may be disposed to reinforce the center portion of the radome 400.

When the antenna assembly 1000 includes a plurality of supports 300, the antenna assembly 1000 may further include a reinforcing member 390 connecting two or more of the plurality of supports 300 to each other. When two or more supporting members 300 are connected to each other by using the reinforcing member 390, it is possible to prevent the supporting members 300 from being collapsed or separated due to the lateral reinforcement of the supporting members 300. As the reinforcing member 390, materials such as plastic rods and wires can be used. Each support 300 may be associated with a reinforcement member 390, for which a predetermined groove or hole may be machined into the support 300.

9 is a cross-sectional perspective view showing an embodiment of a support in an antenna assembly according to another embodiment of the present invention. In FIG. 9, the components under the reflection plate 100 and the radiators 200 are omitted to facilitate understanding of the embodiment.

As described above, the support 300 according to an embodiment of the present invention may include a support portion 340, a leg portion 350, and a coupling portion 360.

The support portion 340 may have a shape similar to the inner surface of the radome 400, as in the example of FIG. While the radome 400 having a certain degree of hardness is constantly in contact with the support portion 340, the support portion 340 may provide resistance against external pressure to reinforce the radome 400. If the contact area of the support part 340 with the radome 400 is too small, the pressure can be concentrated and a shearing force can be applied. Therefore, the support part 340 can be formed wide and flat in correspondence with the inner surface of the radome 400.

The coupling portion 360 may be coupled to the reflection plate 100. The coupling portion 360 may be coupled to the reflection plate 100 by various methods such as adhesive, fastening means, and the like. If the contact area of the coupling part 360 with the reflection plate 100 is too small, the pressure can be concentrated and a shearing force can be applied to the reflection plate 100. Therefore, the coupling part 360 is formed to be wide and flat . As a result, the support 300 may have an "I" -shaped cross section when viewed from the side.

In order to more effectively disperse the pressure, the engaging portion 360 may be formed across the entire width of the reflection plate 100 from one side of the reflection plate 100 to the other side.

The leg portion 350 may extend from the support portion 340 to the engaging portion 360 and may disperse external pressure received by the support portion 340 from the inner surface of the radome 400 into the reflector 100. As in FIG. 9, it may be advantageous to use a plurality of legs 350 when the support 300 has a relatively large width. By using a plurality of legs 350 and providing an empty space between the legs 350, the material used for the support 300 can be saved. Of course, if necessary, one member without any empty space may serve as the leg 350.

According to some embodiments of the present invention, one or more supports reinforce the radome. This allows the radome to bear a higher external pressure while maintaining a smaller thickness. Because the thickness of the radome is low, the overall weight of the antenna assembly is kept low, while maintaining the low weight while providing the necessary strength, allowing for easier and less expensive installation of the antenna assembly.
