1 is a simplified illustration of a base station, a repeater including an antenna array, and a window.

The base station 110 outputs radio waves through an antenna, and radio waves output from the antenna of the base station 110 may be transmitted to the repeater 120 . Conversely, as described above, the base station 110 may receive the radio waves output by the repeater 120, but in this specification, the case where the base station 110 is the transmitting side and the repeater 120 is the receiving side will be described as an example. do.

The repeater 120 is an end device connected to a network, and may include, for example, a modem, a set-top box, and a terminal. The repeater 120 (customer premises equipment) may be provided indoors, and may be particularly disposed in the vicinity of the window 130.

The wireless communication frequency band of the base station 110 and the repeater 120 may be a very high frequency (eg, 28 GHz) band. As is known, when a high frequency band is used in an ultra-high frequency band, there is an advantage in transmission speed, but radio wave attenuation is inevitably severe.

Accordingly, in a communication system using ultra-high frequency communication, it is preferable to place the repeater 120 that communicates with the base station 110 outside a building. However, if the repeater 120 is placed outside the building, there is a high risk of damage to the repeater due to external factors (rain, snow, external impact, etc.).

In conclusion, it is preferable to place the repeater 120 inside the building, and accordingly, as described above, a method of placing the repeater 120 near the window 130 inside the building is being considered. This is because radio wave attenuation through the window 130 is less than radio wave attenuation due to the building wall.

Hereinafter, various embodiments in which the repeater 120 may be placed in the vicinity of the window 130 are provided. More specifically, the repeater 120 may be coupled to the window 130 through an installation aid, and the installation aid and the window 130 may be coupled in various ways.

On the other hand, Figure 1 is merely an illustration of the actual use form of various embodiments of the present invention, the configuration and actual use form of the base station 110, repeater 120 is not limited thereto. That is, in various embodiments of the present invention, transmission of radio waves transmitted from an antenna of a first device (eg, base station 110) to an antenna of a second device (eg, repeater 120) can be improved. It may relate to a window product or a film laminate for attaching to a window, and the type or actual use of the first device and the second device is not determined.

2 is a view showing an embodiment of an antenna assembly according to the present invention.

The antenna assembly 200 according to the present invention is composed of an antenna array 201 including at least one antenna, at least one insulating material, and is spaced apart from the antenna array by a predetermined first distance to form a window (window, 231) A film layer 221 bonded to one surface of, a lens 211 spaced apart from the antenna array by a predetermined second distance and disposed between the antenna array and the film layer, and one surface is fixed and attached to the window, and the other surface may include an installation aid 241 in which the antenna array mounting portion and the lens mounting portion are formed.

Meanwhile, in the antenna assembly 200 according to the present invention, the lens 211 is not an essential component. Depending on the characteristics of the antenna array 201 and the film layer 221, the lens may be omitted. However, since the lens 211 has an effect of improving the gain value of the beam by changing the phase of the beam emitted through the antenna array 201, the lens 211 is included in the antenna assembly 200 to form an antenna assembly. It would be desirable to improve the performance of (200). A more detailed operation and configuration of the lens 211 will be described later.

In addition, the dielectric constant of the insulating material constituting the film layer 221 according to the present invention may be lower than the dielectric constant of the window 231 and higher than that of air, and through this, the window 231 of the radio waves incident to the window 231 The transmission loss for (231) can be reduced.

As shown in FIG. 2 , the film layer 221 may be disposed not only on the inner side of the building but also on the outer side of the window. That is, film layers may be disposed on both inner and outer surfaces of the window. A more specific operation and configuration of the film layer 221 will be described later.

As described above, in the installation aid 241 according to the present invention, a seating portion can be formed on which the antenna array 201, the film layer 221, and the lens 211 can be seated, respectively. The installation aid 241 may be formed as an integral type that is fixedly coupled to the window 231 or may be formed as a separate type capable of being coupled with the window 231 .

Whether to combine the installation aid with the window integrally or separately may be determined based on the performance of the antenna assembly, the location of the window, or the shape of the window. For example, if radio waves are always incident at a fixed position within a window, it would be desirable to couple the antenna assembly to the window through an integral installation aid. On the other hand, if it is unclear whether the antenna assembly is coupled to the window and radio waves are irregularly incident within the window, it may be desirable to couple the antenna assembly to the window through a detachable installation aid.

Therefore, in the following, the antenna assembly structure according to the embodiment of the present invention will be divided into integral type and separate type in more detail. On the other hand, since FIG. 2 discloses an antenna assembly structure as an embodiment according to an embodiment of the present invention, the scope of the present invention should not be limited to the antenna assembly structure shown in FIG. 2.

3 is a diagram showing a first embodiment of an integrated antenna assembly structure.

The antenna assembly 301 according to one embodiment of the present invention may be fixed and attached to the door frame (sill, 331) of the window 321. More specifically, the antenna assembly 301 according to the present invention may include an installation aid 311 fixedly coupled to the door frame 331 .

On the other hand, as disclosed above, since the antenna assembly structure shown in FIG. 3 is an integral antenna assembly structure, the installation aid 311 may be integrally formed with the window frame 331 when forming the window frame 331. there is.

That is, the user can use mobile communication through the window 321 by coupling only the antenna array and the lens to the antenna array mounting portion and the lens mounting portion of the installation aid 311 formed on the window frame 331 .

4 is a diagram showing a second embodiment of an integrated antenna assembly structure.

The antenna assembly 401 according to one embodiment of the present invention may be fixed and attached to the frame of the window 421 . More specifically, the antenna assembly 401 according to the present invention may include an installation aid 411 fixedly coupled to the window 421 frame.

Meanwhile, as described above, since the antenna assembly structure shown in FIG. 4 is an integral antenna assembly structure, the installation aid 411 may be integrally formed with a window frame when forming a window frame in a building.

That is, the user can use the moving box through the window 421 by coupling only the antenna array and the lens to the antenna array mounting portion and the lens mounting portion of the installation aid 411 formed on the window frame.

Meanwhile, although FIG. 4 shows only a structure in which the installation aids are integrally formed on the side of the window frame, the scope of the present invention should not be limited thereto, and the installation aids may be formed anywhere on the top, bottom, left, and right sides of the window frame.

In addition, in addition to the window frame or frame disclosed in FIGS. 3 and 4, a method of directly and integrally coupling the installation aid to the window surface may be considered. In this case, the installation aid may be formed of a material that is fixedly coupled to the window and integrally formed with the window.

That is, the present invention discloses an antenna assembly in which a window and an installation aid are integrally formed, and an antenna array coupled to the installation aid can communicate with an external communication means (base station or terminal) through the window. .

Meanwhile, the antenna array may also be detachable or attached to the installation aid like the lens previously disclosed. More specifically, the installation aid and the antenna array may be coupled so as to be detachable and attached to each other through a fitting method or the like. (If this is followed, the antenna array can be attached and detached, which can have an advantageous effect in terms of antenna array maintenance.)

Unlike the previously disclosed integral antenna assembly structure, the window and the antenna assembly may be configured as a separate type. That is, the window and the antenna assembly may be coupled to each other through a separate configuration without the installation aid for coupling the window to the antenna array.

Meanwhile, in the separate type antenna assembly structure, the arrangement of the film layer, the lens, and the antenna array is the same as that of the integrated type antenna assembly structure. Therefore, the description of the film layer, the lens, and the antenna array in the separate antenna assembly structure is replaced with the description of the integrated antenna assembly structure.

However, unlike the one-piece antenna assembly structure in which the installation aid is formed with the window and one body, in the detachable antenna assembly structure, the installation aid is formed separately from the window. Therefore, hereinafter, it is intended to provide an installation aid for the detachable antenna assembly and how it can be coupled to the window.

On the other hand, since the following shows an embodiment in which the detachable antenna assembly structure can be combined with a window, the scope of the present invention should not be limited only to the embodiment shown below.

5 is a diagram showing a first embodiment of a detachable antenna assembly structure.

According to the first embodiment of the detachable antenna assembly structure, a protrusion 512 may be formed on one surface of the installation aid 511 . For example, the protrusion 512 may be formed of a screw having a screw thread. Meanwhile, a groove may be formed in the window 521 at a position corresponding to the protrusion of the installation aid. For example, a screw thread corresponding to a screw thread of the protruding portion may be formed in the groove.

Accordingly, the antenna assembly 501 may be coupled to the window 521 by coupling the screw to the groove. Meanwhile, in the case of the first embodiment, a groove for fitting should be formed in the window 521 . Therefore, it is preferable that the fitting position is a place where the rigidity of the material is high, such as a window frame or a door frame.

5 shows a case in which a protrusion 512 is formed on the installation aid 511 and a groove is formed on the window 521, but a protrusion is formed on the window 521 and a groove is formed on the installation aid 511. It is free to be That is, the scope of the present invention should not be limited to the structure of FIG. 5 .

6 is a diagram showing a second embodiment of a detachable antenna assembly structure.

According to the second embodiment of the detachable antenna assembly structure, a claw 612 may be formed on one surface of the installation aid 611 . For example, the installation aid 611 may grip the frame or door frame of the window 621 through the tongs 612, and through this, the antenna assembly 601 may be fixedly coupled to the window 621.

Meanwhile, the second embodiment may be combined with the previously disclosed first embodiment. That is, a protrusion is formed on the tongs formed on the installation aid, and the antenna assembly and the window can be more firmly coupled through the protrusion. (The third to fifth embodiments to be described later may also be crossed and combined.)

7 is a view showing a third embodiment of a detachable antenna assembly structure.

According to the third embodiment of the detachable antenna assembly structure, a compression portion 712 may be formed on one surface of the installation aid 711 . For example, a plurality of crimping parts 712 may be formed on one surface of the installation aid at predetermined intervals, and the antenna assembly 701 and the window 721 may be fixedly coupled through the plurality of crimping parts 712. there is.

In the case of the third embodiment, unlike the first embodiment or the second embodiment, there is an advantage in that the antenna assembly can be directly coupled to the glass surface instead of the window frame or the window frame. In addition, the installation of the antenna assembly can be simplified compared to the first embodiment or the second embodiment.

8 is a diagram showing a fourth embodiment of a detachable antenna assembly structure.

According to the fourth embodiment of the detachable antenna assembly structure, an adhesive portion 812 may be formed on one surface of the installation aid 811 . For example, a plurality of adhesive parts 812 may be formed on one surface of the installation aid at predetermined intervals, and the antenna assembly 801 and the window 821 may be fixedly coupled through the plurality of adhesive parts 812.

The fourth embodiment also has the advantage that the antenna assembly can be directly coupled to the glass surface in the same manner as the third embodiment. In addition, the fourth embodiment has the advantage that the installation of the antenna assembly is the simplest compared to other embodiments.

9 is a view showing a fifth embodiment of a detachable antenna assembly structure.

According to the fifth embodiment of the detachable antenna assembly structure, a slide groove 912 may be formed on one surface of the installation aid 911 . For example, a slide protrusion corresponding to the slide groove may be formed on a window frame or a window frame, and the installation aid 911 may be slidably coupled to the slide protrusion. That is, the antenna assembly 901 and the window 921 may be fixedly coupled through the slide groove 912 .

10A and 10B show a window and a film layer attached to the window according to an embodiment of the present invention.

The first embodiment of the present invention is to reduce reflection of radio waves passing through the window from the outside by attaching a film layer 1010 made of an insulating material to a window 1020 made of a general glass material.

According to the above embodiment, the film layer 1010 is composed of at least one insulating material and may be bonded to one surface of the window 1020 . When the film layer 1010 is attached to the window 1020, it is for reducing transmission loss of radio waves to the window 1020.

According to this embodiment, the window 1020 may be a general glass that does not contain a metal material. As is known, the permittivity of a window made of glass is about 6 to 7 F/m, and the permittivity of air may be about 1 F/m. This difference in permittivity results in an increase in the reflectance of radio waves output from the base station and passing through the window 1020, which may be a factor that interferes with reception of radio waves by a repeater located indoors.

Accordingly, the permittivity of the film layer 1010 may be lower than that of the window 1020 and higher than that of the air 1030 in order to reduce reflectance due to a difference in permittivity between the air 1030 and the window 1020. For example, the permittivity of the film layer 1010 may be 2 to 4 F/m.

According to an embodiment, the film layer 1010 may include a plurality of film layers, and each film layer may have a different permittivity. In this case, the permittivity of each film layer may be lower than that of the window 1020 and higher than that of the air 1030, and may be attached close to the window in order of higher permittivity.

According to an embodiment, the thickness of the film layer 1010 may be determined such that the total thickness is proportional to the wavelength of the radio wave when attached to the window 1020, which is determined by considering the thickness of the window 1020 and the frequency thickness of the radio wave. can be determined

11A and 11B show a window and a film layer attached to the window according to an embodiment of the present invention.

The film layer 1110 may include an insulating layer and an electrode layer. The size of the film layer 1110 is not fixed, but at least considering the distance to the repeater, when radio waves pass through the window 1120 from the outside and reach the repeater, it may be equal to or larger than the size of an area through which radio waves can pass. As shown in FIG. 11A , one surface of the insulating layer may be attached to the window 1120 through an adhesive.

Depending on the physical characteristics, propagation loss may occur due to reflection inside the glass, and the propagation loss value may be reduced by the attachment of the film layer 1110.

According to various embodiments, the multi-layer windows 1132 and 1134 may be used, and a plurality of film layers 1112 and 1114 may be attached to the respective windows 1132 and 1134 constituting the multi-layer windows 1132 and 1134. there is. The electrode patterns of the film layers 1112 and 1114 attached to each window 1120 may be the same.

In the case of the multi-layer windows 1132 and 1134, reflection occurs due to the high dielectric constant of the glass, and destructive interference occurs due to signals re-reflected inside the multi-layer windows 1132 and 1134. If they are located close to each other, performance degradation may occur due to reflected waves. According to various embodiments of the present invention, when the film layers 1112 and 1114 are attached to each of the multi-layer windows 1132 and 1134, the propagation loss value can be reduced by reducing the causes exemplified above.

12 is a diagram of an antenna assembly 1201 according to various embodiments of the present invention.

An antenna assembly 1201 according to various embodiments of the present invention may include an antenna array 1200 and a lens 1210. The lens 1210 includes a plurality of unit cells, and the unit cells can vary the refractive index of radio waves according to their own permittivity. The lens 1210 may correct a phase by refracting radio waves emitted from the antenna array 1200 .

The lens 1210 according to various embodiments of the present invention arranges unit cells having the same permittivity in the x-axis direction and unit cells having different permittivities in the y-axis direction, so that radio waves radiated from the antenna array 1200 When passing in the x-axis direction, the coverage of the output radio wave may be amplified by having the same phase as the radio wave incident on the lens 1210 .

A unit cell according to various embodiments of the present invention may have a three-dimensional shape having a unit area and height. Although the unit cells have the same unit area, the permittivity between the unit cells may vary depending on the material or height of the dielectric constituting the unit cells. For example, when unit cells have the same unit area and dielectric material, the permittivity may vary depending on the height between the unit cells.

When unit cells included in the lens 1210 have the same unit area and height, the unit cells may have different dielectric constants depending on the material of the dielectric. When unit cells having the same unit area and height are arranged on both the x-axis and the y-axis in the lens 1210, the lens 1210 according to various embodiments of the present invention has the same dielectric material in the x-axis direction, , Lens 1210 when radio waves emitted from the antenna array 1200 pass in the x-axis direction by arranging unit cells having the same permittivity and arranging unit cells having different permittivities due to different dielectric materials in the y-axis direction. ) to have the same phase as the incident radio wave, so that the coverage of the output radio wave can be amplified.

Since the permittivity may vary depending on the unit area and the height between unit cells having the same dielectric material, the lens 1210 arranges unit cells having the same height in the x-axis direction and unit cells having different heights in the y-axis direction. By arranging the radio wave emitted from the antenna array 1200 to have the same phase as the radio wave incident on the lens 1210 when passing in the x-axis direction, the coverage of the radio wave output can be amplified.

For example, when the dielectric material and unit area of the unit cells constituting the lens 1210 are the same, the permittivity may be different by varying the height. Unit cells forming a pattern may have the same height, and unit cells between different patterns may have a height difference.

The lens 1210 according to various embodiments of the present invention may change the phase of radio waves emitted from the antenna array 1200 by forming a metal pattern on the lens 1210 without disposing unit cells.

13 is a diagram of an antenna assembly 1301 according to various embodiments of the present invention.

An antenna assembly 1301 according to various embodiments of the present invention may include an antenna array 1300 and a lens 1320. The lens 1320 may include a plurality of unit cells 1320 .

The lens 1310 according to various embodiments of the present invention disposes unit cells 1320 having the same permittivity in the x-axis direction and arranging unit cells having different permittivities in the y-axis direction, thereby generating radiation from the antenna array 1300. When the radio waves passing through the x-axis direction of the lens 1310, the radio wave output to the lens 1310 and the radio wave incident on the lens 1310 have the same phase to amplify the coverage of the output radio wave, When radio waves emitted from the antenna array 1300 pass in the y-axis direction of the lens 1310, all radio waves output to the lens 1310 may have the same phase, so that the gain of the radio waves output may be increased.

The lens 1310 according to various embodiments of the present invention arranges unit cells 1320 having the same permittivity in the x-axis direction and arranging unit cells having different permittivities in the y-axis direction, thereby maintaining the same permittivity in the x-axis direction. The unit cells 1320 may have a linear pattern having a straight line or an open curve.

The lens 1310 according to various embodiments of the present invention may change the phase of radio waves emitted from the antenna array 1300 by forming a metal pattern on the lens 1310 without disposing unit cells. The metal pattern on the lens 1310 may have a linear pattern having a straight line or an open curve in the X-axis direction.

The unit cell 1320 according to various embodiments of the present disclosure may have a three-dimensional shape having a unit area and a height. Although the unit cells 1320 have the same unit area, permittivity between the unit cells may vary depending on the material or height of the dielectric constituting the unit cells. For example, when the unit cells 1320 have the same unit area and material, permittivity may vary depending on the height between the unit cells 1320 .

When the unit cell 1320 included in the lens 1310 has the same unit area and height, the unit cell 1320 may have a different permittivity depending on the material. When unit cells 1320 having the same unit area and height are disposed on both the x-axis and the y-axis in the lens 1310, the lens 1310 according to various embodiments of the present invention has a dielectric material in the x-axis direction. By arranging unit cells 1320 having the same permittivity and having different dielectric materials in the y-axis direction, radio waves radiated from the antenna array 1300 are transmitted in the x-axis direction. In the case of passing in the same direction, the coverage of the output radio wave may be amplified by having the same phase as the radio wave incident on the lens 1310 .

When the unit cell 1320 included in the lens 1310 has the same unit area and dielectric material, the permittivity may vary depending on the height between the unit cells 1320, so the lens 1310 has the same height in the x-axis direction. By arranging unit cells 1320 having and having different heights in the y-axis direction, when radio waves emitted from the antenna array 1300 pass in the x-axis direction, the lens 1310 It is possible to amplify the coverage of the output radio wave by making it have the same phase as the radio wave incident on it.

For example, when the dielectric material and unit area of the unit cells 1320 constituting the lens 1310 are the same, the permittivity may be different by varying the height. Unit cells 1320 forming a pattern may have the same height, and a height difference may occur between unit cells 1320 between different patterns.

The lens 1310 according to various embodiments of the present invention may change the phase of radio waves emitted from the antenna array 1300 by forming a metal pattern on the lens 1310 without disposing unit cells. The metal pattern on the lens 1310 may have a linear pattern having a straight line or an open curve in the X-axis direction.
