Description

Technical Field

[0001] The present invention relates to a transparent antenna configured for a vehicle. The specific embodiments relate to an antenna assembly implemented with a transparent material so that the antenna area cannot be identified on the vehicle glass. Background Art

[0002] Vehicles can perform wireless communication services with other vehicles or surrounding objects, infrastructure or base stations. In this regard, various communication services can be provided by a wireless communication system that applies LTE communication technology or 5G communication technology. On the other hand, a portion of the LTE frequency band can be allocated to provide 5G communication services.

[0003] On the other hand, since the vehicle body and the roof are formed of metal materials, there is a problem of blocking radio waves. Therefore, an additional antenna structure can be arranged on the upper part of the vehicle body or the roof. Alternatively, when the antenna structure is arranged on the lower part of the vehicle body or the roof, the part of the vehicle body or the roof corresponding to the antenna arrangement area can be formed of a non-metallic material.

[0004] However, from the design point of view, the vehicle body or the roof needs to be formed in one piece. In this case, the appearance of the vehicle body or the roof may be formed of a metal material. Therefore, there is a problem that the vehicle body or the roof may cause the antenna efficiency to be greatly reduced.

[0005] In order to increase the communication capacity without changing the exterior design of the vehicle, a transparent antenna can be placed on the glass of the vehicle window. However, there is a problem that the electrical loss of the transparent material antenna deteriorates the antenna radiation efficiency and impedance bandwidth characteristics.

[0006] If an antenna pattern is formed on a dielectric substrate using a metal mesh structure in which a plurality of metal wires are connected to each other, a transparent antenna in which the plurality of metal wires cannot be distinguished by the naked eye can be realized. However, if a metal mesh structure is not formed in a dielectric region surrounding an antenna region in which an antenna pattern is formed, there is a problem that a difference in visibility occurs because the antenna region and the dielectric region can be distinguished by the naked eye.

[0007] In order to solve this problem, a dummy grid may be arranged in the dielectric region. However, the arrangement of the dummy grid interferes with the antenna pattern, so there is a problem that the antenna performance is degraded.

[0008] On the other hand, when a transparent material antenna is arranged on the vehicle glass, the transparent antenna pattern can be configured to be electrically connected to a feeding pattern arranged on an additional dielectric substrate. In this regard, feeding loss and degradation of antenna performance caused by the connection between the transparent antenna pattern and the feeding pattern may occur. In addition, a transparency difference may occur between a transparent region (transparent region) formed with a transparent antenna pattern and an opaque region (opaque region) formed with a feeding pattern. Due to this transparency difference, the area where the antenna is arranged and other areas can be distinguished with the naked eye. Despite this transparency difference, there is still a need for a technical solution for minimizing the visibility difference between the antenna area and other areas in the vehicle glass. Summary of the invention

[0013] Still another object of the present specification is to perform a multiple-input multiple-output (MIMO) operation for improving isolation characteristics in each of a plurality of frequency bands.

[0014] Another object of the present specification is to provide a broadband antenna structure made of a transparent material that can operate in a broadband and reduce feed loss and improve antenna efficiency.

[0015] Another object of the present specification is to improve the efficiency of the feeding structure of a broadband transparent antenna assembly that can be configured on vehicle glass and to ensure the reliability of the mechanical structure including the feeding structure.

[0017] Yet another object of the present specification is to ensure the invisibility of a transparent antenna and an antenna assembly including the same without deteriorating the antenna performance.

[0018] Still another object of the present specification is to simultaneously ensure invisibility with respect to the shape of the antenna assembly and ensure invisibility when the antenna assembly is attached to a display or glass.

[0107] Hereinafter, an antenna assembly (antenna module) that can be placed on a vehicle window and a vehicle antenna system including the antenna assembly are described. Herein, the antenna assembly refers to a structure in which a conductive pattern is bonded to a dielectric substrate, and may also be referred to as an antenna module.

[0108] Regarding this, Figure 1 FIG. 1 is a diagram showing a glass of a vehicle on which an antenna structure can be arranged according to an embodiment of the present specification. Figure 1 The vehicle 500 may include a front glass 310, a door glass 320, a rear glass 330, and a corner window glass 340. On the other hand, the vehicle 500 may further include an upper glass 350 formed at a roof in an upper region.

[0109] Therefore, the glass constituting the window of the vehicle 500 may include a front glass 310 arranged in the front area of ​​the vehicle, a door glass 320 arranged in the door area of ​​the vehicle, and a rear glass 330 arranged in the rear area of ​​the vehicle. On the other hand, the glass constituting the window of the vehicle 500 may also include a corner window glass 340 arranged in a part of the door area of ​​the vehicle. In addition, the glass constituting the window of the vehicle 500 may also include an upper glass 350, which is separated from the rear glass 330 and is arranged in the upper area of ​​the vehicle. Therefore, each glass constituting the window of the vehicle 500 may also be referred to as a window.

[0110] The front glass 310 prevents the wind from the front direction from blowing into the interior of the vehicle, and thus can be called a front windshield. The front glass 310 can be formed in a double-layer joint structure with a thickness of about 5.0 to 5.5 mm. The front glass 310 can be formed in a joint structure of glass / anti-shatter film / glass.

[0111] The door glass 320 may be formed of a double-layered joint structure or a single-layered compressed glass. The rear glass 330 may be formed of a double-layered joint structure or a single-layered compressed glass having a thickness of about 3.5 to 5.5 mm. In the rear glass 330, a distance is required between the hot wire, the AM / FM antenna, and the transparent antenna. The corner window glass 340 may be formed of a single-layered compressed glass having a thickness of about 3.5 to 4.0 mm, but is not limited thereto.

[0112] The size of the corner window glass 340 varies according to the type of vehicle, and the size of the corner window glass 340 may be smaller than the size of the front glass 310 and the size of the rear glass 330 .

[0113] Hereinafter, the structure in which the antenna assembly of this specification is arranged in different regions of the front glass of the vehicle will be described. The antenna assembly attached to the vehicle glass can be implemented as a transparent antenna. Figure 2a Indicated in Figure 1 A front view of a vehicle in which antenna assemblies are arranged at different areas of the front glass of the vehicle. Figure 2b Indicated in Figure 1 A perspective view of the interior front of a vehicle in which antenna assemblies are arranged at different areas of a front glass of the vehicle. Figure 2c Indicated in Figure 1 A side perspective view of a vehicle with an antenna assembly configured on an upper glass of the vehicle.

[0114] Reference Figure 2a , the front view of the vehicle 500 represents the configuration of the transparent antenna for the vehicle of the present specification that can be configured. The window glass assembly (pane assembly) 22 may include an antenna in the upper area 310a. The window glass assembly 22 may include an antenna in the upper area 310a, an antenna in the lower area 310b and / or an antenna in the side area 310c. In addition, the window glass assembly 22 may include a translucent pane glass 26 formed by a dielectric substrate. The antenna in the upper area 310a, the antenna in the lower area 310b and / or the antenna in the side area 310c are configured to support at least one of various communication systems.

[0115] The antenna module 1100 can be implemented in the upper area 310a, or the lower area 310b or the side area 310c of the front glass 310. In the case where the antenna module 1100 is configured in the lower area 310b of the front glass 310, the antenna module 1100 can be extended to the main body 49 of the lower area of ​​the translucent window glass 26. The main body 49 of the lower area of ​​the translucent window glass 26 can be implemented to have lower transparency than other parts. In the main body 49 of the lower area of ​​the translucent window glass 26, a part of the feed part or other interface lines can be implemented. The connector assembly 74 can be implemented in the main body 49 of the lower area of ​​the translucent window glass 26. The main body 49 of the lower area can constitute a vehicle body of a metal material.

[0116] Reference Figure 2b The antenna assembly 1000 may include a telematics control unit (TCU) 300 and an antenna module 1100. The antenna module 1100 may be disposed in different regions of the vehicle glass.

[0117] Reference Figure 2a and Figure 2b , the upper area 310a, the lower area 310b and / or the side area 310c of the vehicle glass may be configured with an antenna assembly. Figure 2a to Figure 2c Antenna assemblies may be disposed on the front glass 310 , the rear glass 330 , the corner window glass 340 , and the upper glass 350 of the vehicle.

[0118] Reference Figure 2a to Figure 2c , the antenna in the upper area 310a of the front glass 310 of the vehicle can be configured to operate in the LB (low band), MB (mid band), HB (high band) and 5G Sub6 bands of the 4G / 5G communication system. The antenna in the lower area 310b and / or the antenna in the side area 310c can also be configured to operate in the LB, MB, HB and 5G Sub6 bands of the 4G / 5G communication system. In the rear glass 330 of the vehicle, the antenna structure 1100b can also be configured to operate in the LB, MB, HB and 5G Sub6 bands of the 4G / 5G communication system. In the upper glass 350 of the vehicle, the antenna structure 1100c can also be configured to operate in the LB, MB, HB and 5G Sub6 bands of the 4G / 5G communication system. In the corner window glass 350 of the vehicle, the antenna structure 1100d can also be configured to operate in the LB, MB, HB and 5G Sub6 bands of the 4G / 5G communication system.

[0119] At least a portion of the outer contour area of ​​the front glass 310 of the vehicle may be formed by the translucent window glass 26. The translucent window glass 26 may include: a first portion, formed with a portion of the antenna and the feeder; and a second portion, formed with a portion of the feeder and a dummy structure. In addition, the translucent window glass 26 may also include a dummy area where no conductive pattern is formed. As an example, the transparent area of ​​the window glass assembly 22 may be formed to be transparent to ensure light transmission and field of view.

[0120] Although the conductive pattern is illustrated as being formed on a portion of the front glass 310, it can be extended to being formed on Figure 1 The side glass 320, the rear glass 330 and any other glass structures of the vehicle 500 can be seen by the passenger or driver through the window glass assembly 22. In addition, the passenger or driver can see the road and the surrounding environment without being blocked by the antenna of the upper area 310a, the antenna of the lower area 310b and / or the antenna of the side area 310c.

[0121] Vehicle 500 may be configured to communicate with pedestrians, surrounding infrastructure and / or servers in addition to surrounding vehicles. Figure 3 Indicates the type of V2X application. Figure 3 V2X (Vehicle-to-Everything) communication includes V2V (Vehicle-to-Vehicle) which refers to the communication between vehicles, V2I (Vehicle to Infrastructure) which refers to the communication between vehicles and eNB or RSU (Road Side Unit), V2P (Vehicle-to-Pedestrian) which refers to the communication between vehicles and terminals carried by individuals (pedestrians, cyclists, vehicle drivers or passengers), V2N (vehicle-to-network), and other communications between vehicles and all individuals.

[0122] on the other hand, Figure 4 This is a block diagram for explaining a vehicle and an antenna system mounted on the vehicle according to an embodiment of the present specification.

[0123] The vehicle 500 may include a communication device 400 and a processor 570. The communication device 400 may correspond to a telematics control unit of the vehicle 500.

[0124] The communication device 400 is a device for performing communication with an external device. Here, the external device may be another vehicle, a mobile terminal or a server. In order to perform communication, the communication device 400 may include at least one of a transmitting antenna, a receiving antenna, an RF (Radio Frequency) circuit and an RF element capable of implementing various communication protocols. The communication device 400 may include a short-range communication unit 410, a location information unit 420, a V2X communication unit 430, an optical communication unit 440, a 4G wireless communication module 450 and a 5G wireless communication module 460. The communication device 400 may include a processor 470. According to an embodiment, the communication device 400 may also include other constituent elements in addition to the described constituent elements, or may not include a part of the described constituent elements.

[0125] The 4G wireless communication module 450 and the 5G wireless communication module 460 can perform wireless communication with more than one communication system through one or more antenna modules. The 4G wireless communication module 450 can send and / or receive signals with a device in the first communication system through a first antenna module. In addition, the 5G wireless communication module 460 can send and / or receive signals with a device in the second communication system through a second antenna module. The 4G wireless communication module 450 and the 5G wireless communication module 460 can also be physically implemented as an integrated communication module. Here, the first communication system can be an LTE communication system, and the second communication system can be a 5G communication system. However, the first communication system and the second communication system are not limited to this, and can be extended to any communication system that is different from each other.

[0126] The processor of the device in the vehicle 500 can be implemented by an MCU (Micro Control Unit) or a modem. The processor 470 of the communication device 400 is equivalent to a modem, and the processor 470 can be implemented as an integrated modem. The processor 470 can obtain surrounding information from other surrounding vehicles, objects, or infrastructure through wireless communication. The processor 470 can use the acquired surrounding information to perform vehicle control.

[0127] The processor 570 of the vehicle 500 may be a processor of a CAN (Car Area Network) or an ADAS (Advanced Driver Assistance System), but is not limited thereto. When the vehicle 500 is implemented in a distributed control manner, the processor 570 of the vehicle 500 may be replaced by a processor of each device.

[0128] On the other hand, the antenna module configured inside the vehicle 500 may include a wireless communication unit. The 4G wireless communication module 450 can transmit and receive 4G signals with a 4G base station through a 4G mobile communication network. At this time, the 4G wireless communication module 450 can transmit more than one 4G transmission signal to the 4G base station. In addition, the 4G wireless communication module 450 can receive more than one 4G reception signal from the 4G base station. In this regard, uplink (UL: Up-Link) multiple-input multiple-output (MIMO: Multi-Input Multi-Output) can be performed by transmitting a plurality of 4G transmission signals to the 4G base station. In addition, downlink (DL: Down-Link) multiple-input multiple-output (MIMO: Multi-Input Multi-Output) can be performed by receiving a plurality of 4G reception signals from the 4G base station.

[0129] The 5G wireless communication module 460 can transmit and receive 5G signals with the 5G base station through the 5G mobile communication network. Here, the 4G base station and the 5G base station can be non-independent (NSA: Non-Stand-Alone) structures. For example, the 4G base station and the 5G base station can be configured as a non-independent (NSA: Non Stand-Alone) structure. Alternatively, the 5G base station can be configured as an independent (SA: Stand-Alone) structure at a location different from the 4G base station. The 5G wireless communication module 460 can transmit and receive 5G signals with the 5G base station through the 5G mobile communication network. At this time, the 5G wireless communication module 460 can transmit more than one 5G transmission signal to the 5G base station. In addition, the 5G wireless communication module 460 can receive more than one 5G reception signal from the 5G base station. At this time, the 5G frequency band can use the same frequency band as the 4G frequency band, and it is called LTE reconfiguration (re-farming). On the other hand, as a 5G frequency band, the Sub6 frequency band, which is a frequency band below 6GHz, can be used. On the contrary, in order to perform broadband high-speed communication, the millimeter wave (mmWave) frequency band can be used as the 5G frequency band. In the case of using the millimeter wave (mmWave) frequency band, electronic devices can perform beam forming to expand the communication coverage with the base station.

[0130] On the other hand, regardless of the 5G frequency band, in order to increase the transmission speed, a larger number of multiple-input multiple-output (MIMO) can be supported in the 5G communication system. In this regard, uplink (UL: Up-Link) MIMO can be performed by transmitting a plurality of 5G transmission signals to a 5G base station. In addition, downlink (DL: Down-Link) MIMO can be performed by receiving a plurality of 5G reception signals from a 5G base station.

[0131] On the other hand, through the 4G wireless communication module 450 and the 5G wireless communication module 460, it is possible to be in a dual connection (DC: Dual Connectivity) state with the 4G base station and the 5G base station. The dual connection with the 4G base station and the 5G base station as described above may be referred to as EN-DC (EUTRAN NR DC). On the other hand, if the 4G base station and the 5G base station are co-located structures, the throughput can be improved by heterogeneous carrier aggregation (inter-CA (Carrier Aggregation)). Therefore, if the 4G base station and the 5G base station are in the EN-DC state, the 4G reception signal and the 5G reception signal can be received simultaneously by the 4G wireless communication module 450 and the 5G wireless communication module 460. On the other hand, the 4G wireless communication module 450 and the 5G wireless communication module 460 can be used to perform close range communication between electronic devices (e.g., vehicles). In one embodiment, wireless communication can be performed in a V2V manner between vehicles without via a base station after resources are allocated.

[0132] On the other hand, in order to improve the transmission speed and converge the communication system, at least one of the 4G wireless communication module 450 and the 5G wireless communication module 460 and the Wi-Fi (Wireless High Fidelity) communication module 113 may be used to perform carrier aggregation (CA). In this regard, 4G+WiFi carrier aggregation (CA) may be performed using the 4G wireless communication module 450 and the Wi-Fi communication module 113. Alternatively, 5G+WiFi carrier aggregation (CA) may be performed using the 5G wireless communication module 460 and the Wi-Fi communication module.

[0133] On the other hand, the communication device 400 may realize a vehicle display device together with the user interface device. In this case, the vehicle display device may be named a telematics device or an AVN (Audio Video Navigation) device.

[0134] On the other hand, the broadband transparent antenna structure that can be configured on the glass of a vehicle of the present specification can be implemented by a single dielectric substrate on the same plane as the CPW feeder. In addition, the broadband transparent antenna structure that can be configured on the glass of a vehicle of the present specification can be implemented with a structure in which grounding is formed on both sides of the radiator, thereby forming a broadband structure.

[0135] The following describes the antenna components related to the broadband transparent antenna structure of this specification. Figure 5a to Figure 5c This shows the configuration in which the antenna assembly of this specification is disposed on the vehicle glass. Figure 5a , the antenna assembly 1000 may include a first dielectric substrate 1010a and a second dielectric substrate 1010b. The first dielectric substrate 1010a may be implemented as a transparent substrate, and thus may be referred to as a transparent substrate 1010a. The second dielectric substrate 1010b may be implemented as an opaque substrate 1010b.

[0136] The glass panel 310 may include a transparent glass region 311 and an opaque region 312. The opaque region 312 of the glass panel 310 may be a frit region formed by a frit layer. The opaque region 312 may be formed to surround the transparent region 311. The opaque region 312 may be formed in an outer region of the transparent region 311. The opaque region 312 may form a boundary region of the glass panel 310.

[0137] The signal pattern formed on the dielectric substrate 1010 can be connected to the telematics control unit (TCU) 300 through a connector component 313 such as a coaxial cable. The telematics control unit (TCU) 300 can be configured inside the vehicle, but is not limited thereto. The telematics control unit (TCU) 300 can be configured in the dashboard inside the vehicle or in the roof area inside the vehicle, but is not limited thereto.

[0138] Figure 5b The antenna assembly 1000 is shown as being disposed in a partial region of the glass panel 310 . Figure 5c The structure in which the antenna assembly 1000 is arranged over the entire area of ​​the glass panel 310 is shown.

[0139] Reference Figure 5b and Figure 5c, the glass panel 310 may include a transparent area 311 and an opaque area 312. The opaque area 312 is a non-visible area whose transparency is below a specified level, and may be referred to as a frit area, or a BP (Black Printing) area, or a BM (Black Matrix) area. The opaque area 312, which is equivalent to the opaque area, may be formed to surround the transparent area 311. The opaque area 312 may be formed in an outer area of ​​the transparent area 311. The opaque area 312 may form a boundary area of ​​the glass panel 310. A second dielectric substrate 1010b or hot wire pads 360a, 360b, which is equivalent to a feed substrate, may be arranged in the opaque area 312. The second dielectric substrate 1010b arranged in the opaque area 312 may be referred to as an opaque substrate. As Figure 5c As shown, when the antenna assembly 1000 is disposed on the entire area of ​​the glass panel 310 , the heat wire pads 360 a and 360 b may also be disposed in the opaque area 312 .

[0140] Reference Figure 5b , the antenna assembly 1000 may include a first transparent dielectric substrate 1010a and a second dielectric substrate 1010b. Figure 5b and Figure 5c , the antenna assembly 1000 may include an antenna module 1100 formed by a conductive pattern and a second dielectric substrate 1010b. The antenna module 1100 may be formed by a transparent electrode portion and implemented as a transparent antenna module. The antenna module 1100 may be implemented by more than one antenna element. The antenna module 1100 may include a MIMO antenna and / or other antenna elements for wireless communication. Other antenna elements may include at least one of GNSS / radio / broadcast / WiFi / satellite communication / UWB (ultra-wideband), RKE (Remote Keyless Entry) antennas for vehicle applications.

[0141] Reference Figure 5a to Figure 5c , the antenna assembly 1000 can be connected to the telematics control unit (TCU) 300 through the connector component 313. The connector component 313 can be electrically connected to the TCU300 by forming a connector 313c at the end of the cable. The signal pattern of the second dielectric substrate 1010b formed on the antenna assembly 1000 can be connected to the TCU300 using the connector component 313 such as a coaxial cable. Through the connector component 313, the antenna module 1100 can be electrically connected to the TCU300. The TCU300 can be configured inside the vehicle, but is not limited to this. The TCU300 can be configured on the dashboard inside the vehicle or the roof area inside the vehicle, but is not limited to this.

[0142] On the other hand, when the transparent antenna assembly of the present specification is attached to the inside or surface of the glass panel 310 , the transparent electrode portion including the antenna pattern and the dummy pattern may be disposed in the transparent region 311 . Conversely, the opaque substrate portion may be disposed in the opaque region 312 .

[0143] The antenna assembly formed on the vehicle glass of the present specification can be configured in the transparent area and the opaque area. In this regard, Figure 6a Various embodiments of the frit pattern of this specification are shown. Figure 6b and Figure 6c The transparent antenna pattern of the embodiment and the structure in which the transparent antenna pattern is arranged on the vehicle glass are shown.

[0144] Reference Figure 6a (a), the frit pattern 312a can be formed as a metal pattern in a circular (or polygonal, elliptical) shape with a specified diameter. The frit pattern 312a can be configured in a two-dimensional structure along two axial directions. The frit pattern 312a can be formed in an offset structure in which the center points between the patterns forming adjacent rows are separated by a specified interval.

[0145] Reference Figure 6a In (b), the frit pattern 312b may be formed in a rectangular pattern in one axis direction. The frit pattern 312c may be configured in a one-dimensional structure along one axis direction or in a two-dimensional structure along two axis directions.

[0146] Reference Figure 6a (c), the frit pattern 312c may be formed as a groove pattern in which the metal pattern is removed in a circular (or polygonal, elliptical) shape having a prescribed diameter. The frit pattern 312b may be configured in a two-dimensional structure along two axial directions. The frit pattern 312c may be formed in an offset structure in which the center points between the patterns forming adjacent rows are separated by a prescribed interval.

[0147] Reference Figures 5a to 6c In the opaque region 312, the opaque substrate 1010b and the transparent substrate 1010a may be electrically connected. In this regard, in order to make the transparent antenna pattern invisible, a dummy pattern that is electrically very small and below a specified size may be arranged around the antenna pattern. Thus, the pattern in the transparent electrode cannot be distinguished by the naked eye without deteriorating the antenna performance. The dummy pattern may be designed to have a light transmittance similar to that of the antenna pattern within a specified range.

[0148] The transparent antenna assembly including the opaque substrate 1010b bonded to the transparent electrode portion can be mounted on the glass panel 310. In this regard, in order to ensure invisibility, the opaque substrate 1010b connected to the RF connector or the coaxial cable is arranged in the opaque region 312 of the vehicle glass. On the other hand, the transparent electrode portion is arranged in the transparent region 311 of the vehicle glass, thereby ensuring the invisibility of the antenna outside the vehicle glass.

[0149] A portion of the transparent electrode portion may be attached to the opaque region 312 as appropriate. The frit pattern of the opaque region 312 may be formed to form a gradient from the opaque region 312 to the transparent region 311. If the transmittance of the frit pattern and the transmittance of the transparent electrode portion are made consistent within a specified range, the transmission efficiency of the transmission line can be improved while improving the invisibility of the antenna. On the other hand, a metal mesh shape similar to the frit pattern can be used to ensure invisibility while reducing sheet resistance. In addition, by increasing the line width of the metal mesh in the area connected to the opaque substrate 1010b, the risk of disconnection of the transparent electrode layer during manufacturing and assembly can be reduced.

[0150] Reference Figure 6a (a) and Figure 6b , the conductive pattern 1110 of the antenna module may be composed of a metal grid of the same line width in the opaque region 312. The conductive pattern 1110 may include a connection pattern 1110c connecting the transparent substrate 1010a and the opaque substrate 1010b. In the opaque region 312, a frit pattern of a specified shape may be arranged at a specified interval and formed on the connection pattern 1110c and both sides of the connection pattern 1110c. The connection pattern 1110c may include a first transmittance portion 1111c formed with a first transmittance and a second transmittance portion 1112c formed with a second transmittance.

[0151] In the frit pattern 312a formed in the opaque region 312, metal grids of a predetermined diameter may be arranged along one axis and another axis. The metal grids of the frit pattern 312a may be arranged at intersections of the metal grids with the second transmittance portions 1112c of the connection pattern 1110c.

[0152] Reference Figure 6a (b) and Figure 6b In the frit pattern 312b formed in the opaque region 312, the groove grids of the prescribed diameter in which the metal region is removed can be arranged along one axis direction and another axis direction. The groove grids of the frit pattern 312b can be arranged between the metal grids in the connection pattern 1110c. Thus, the metal region of the frit pattern 312b without the groove grids can be arranged at the intersection of the metal grids.

[0153] Reference Figure 6aand Figure 6c , the connection pattern 1110c may be formed of a metal mesh having a first line width W1 in a first transmittance portion 1111c adjacent to the transparent region 311. The connection pattern 1110c may be formed of a second line width W2 thicker than the first line width W1 in a second transmittance portion 1112c adjacent to the opaque substrate 1010b. In this regard, the first transparency of the first transmittance portion 1111c may be set to be higher than the second transparency of the second transmittance portion 1112c.

[0154] like Figure 5a to Figure 5c When the transparent antenna assembly is attached to the inside of the vehicle glass, the transparent electrode portion can be arranged in the transparent region 311, and the opaque substrate 1010b can be arranged in the opaque region 312. In this regard, the transparent electrode portion can be arranged in the opaque region 312 according to the situation.

[0155] A portion of the metal pattern of the low-transmittance pattern electrode portion and the high-transmittance pattern electrode portion located in the opaque region 312 can be arranged in the gradient region of the opaque region 312. In the case where the transmission line portion in the antenna pattern and the low-transmittance pattern electrode is composed of a transparent electrode, a gain drop may occur due to a decrease in transmission efficiency caused by an increase in sheet resistance. As a solution to improve this gain drop, the transmittance of the frit pattern 312 where the electrode is located and the transmittance of the transparent electrode can be made consistent within a specified range.

[0156] By increasing the line width of the transparent electrode in the region with low transmittance in the frit patterns 312a, 312b, 312c or adding the same shape as the frit patterns 312a, 312b, 312c, a lower sheet resistance can be achieved. This can solve the problem of reduced transmission efficiency while ensuring invisibility. The transmittance and pattern of the opaque region 312 are not limited to Figure 6a The structure of the transmission line may vary depending on the glass manufacturer or vehicle manufacturer. Therefore, the shape and transparency (line width and spacing) of the transparent electrode of the transmission line may vary differently.

[0157] Figure 7a Shows a front view and a cross-sectional view of the transparent antenna assembly of this specification. Figure 7b It is a diagram showing the mesh structure of the metal mesh radiator area and the virtual metal mesh area according to the embodiment.

[0158] Figure 7a (a) shows a front view of the transparent antenna assembly 1000. Figure 7a (b) is a cross-sectional view of the transparent antenna component 1000, showing the layered structure of the transparent antenna component 1000. Figure 7a, the antenna assembly 1000 may include a first transparent dielectric substrate 1010a and a second dielectric substrate 1010b. A conductive pattern 1110 acting as a radiator may be configured on one side of the first transparent dielectric substrate 1010a. A feed pattern 1120f and ground patterns 1121g and 1122g may be formed on one side of the second dielectric substrate 1010b. The conductive pattern 1110 acting as a radiator may include more than one conductive pattern. The conductive pattern 1110 may include a first pattern 1111 connected to the feed pattern 1120f and a second pattern 1112 connected to the ground pattern 1121g. The conductive pattern 1110 may also include a third pattern 1113 connected to the ground pattern 1122g.

[0159] The conductive pattern 1110 constituting the antenna module may be implemented as a transparent antenna. Figure 7b , the conductive pattern 1110 may be formed of a metal grid pattern 1020a having a line width below a specified value and forming a metal mesh radiator region. A dummy metal grid pattern 1020b may be formed in the inner region or the outer region between the first pattern 1111 to the third pattern 1113 of the conductive pattern 1100 to maintain transparency below a specified level. The metal grid pattern 1020a and the dummy metal grid pattern 1020b may form a metal mesh layer 1020.

[0160] Figure 7b (a) shows the structure of a typical metal grid pattern 1020a and a dummy metal grid pattern 1020b. Figure 7b (b) shows the structure of an atypical metal grid pattern 1020a and a virtual metal grid pattern 1020b. Figure 7b As shown in (a), the metal mesh layer 1020 can be formed into a transparent antenna structure by a plurality of metal meshes. The metal mesh layer 1020 can be formed in a regular metal mesh shape such as a quadrilateral, a rhombus, or a polygon. The conductive pattern can be formed into a plurality of metal meshes to act as a feeder or a radiator. The metal mesh layer 1020 constitutes a transparent antenna area. As an example, the metal mesh layer 1020 can be implemented with a thickness of about 2 mm, but is not limited thereto.

[0161] The metal mesh layer 1020 may include a metal grid pattern 1020a and a dummy metal grid pattern 1020b. The metal grid pattern 1020a and the dummy metal grid pattern 1020b may form an open area (OA) whose ends are disconnected so as not to be electrically connected. The dummy metal grid pattern 1020b may be formed with slits SL so that the ends of the respective meshes CL1, CL2, ..., CLn are not connected.

[0162] Reference Figure 7b(b), the metal mesh layer 1020 may be formed of a plurality of atypical metal meshes. The metal mesh layer 1020 may include a metal grid pattern 1020a and a dummy metal grid pattern 1020b. The metal grid pattern 1020a and the dummy metal grid pattern 1020b may form an open area OA whose ends are disconnected so as not to be electrically connected. The dummy metal grid pattern 1020b may be formed with slits SL so that the ends of the individual grids CL1, CL2, ..., CLn are not connected.

[0163] On the other hand, the transparent substrate on which the transparent antenna of the present specification is formed can be arranged on the glass of a vehicle. Figure 8a Represents the layered structure of the antenna module and the feeding module. Figure 8b It represents a layered structure in which an antenna module and a feeding structure are combined and an opaque substrate including a combined portion.

[0164] Reference Figure 8a (a), the antenna module 1100 may include a first transparent dielectric substrate 1010a formed on a first layer and a first conductive pattern 1110 formed on a second layer disposed on the first layer. Figure 7b , the first conductive pattern 1110 may be implemented as a metal mesh layer 1020 including a metal lattice pattern 1020a and a dummy metal lattice pattern 1020b. The antenna module 1100 may further include a protective layer 1031 and an adhesive layer 1041a disposed on the second layer.

[0165] Reference Figure 8a (b), the feeding structure 1100f may include a second dielectric substrate 1010b, a second conductive pattern 1120, and a third conductive pattern 1130. The feeding structure 1100f may further include a first protective layer 1033 and a second protective layer 1034, each stacked on the second conductive pattern 1120 and the third conductive pattern 1130. The feeding structure 1100f may further include an adhesive layer 1041b formed on a portion of the second conductive pattern 1120.

[0166] A second conductive pattern 1120 may be disposed on one side of a second dielectric substrate 1010b implemented as an opaque substrate. A third conductive pattern 1130 may be disposed on the other side of the second dielectric substrate 1010b. A first protective layer 1033 may be formed on the upper portion of the third conductive pattern 1130. A second protective layer 1034 may be formed on the lower portion of the second conductive pattern 1120. The first protective layer 1033 and the second protective layer 1034 are configured to have a low dielectric constant (low permittivity) below a specified value, thereby enabling low-loss feeding to the transparent antenna region.

[0167] Reference Figure 8b(a), the antenna module 1100 may be combined with a feeding structure 1100f implemented by a second dielectric substrate 1010b as an opaque substrate. A first conductive pattern 1110 implemented by a metal mesh layer as a transparent electrode layer may be formed on the upper portion of the first transparent dielectric substrate 1010a. A protective layer 1031 may be formed on the upper portion of the first conductive pattern 1110. A protective layer 1031 and a first adhesive layer 1041a may be formed on the upper portion of the first conductive pattern 1110. The first adhesive layer 1041a may be formed adjacent to the protective layer 1031.

[0168] The first adhesive layer 1041a formed on the upper portion of the first conductive pattern 1110 may be bonded to the second adhesive layer 1041b formed on the lower portion of the second conductive pattern 1120. The first transparent dielectric substrate 1010a and the second dielectric substrate 1010b may be bonded by bonding between the first adhesive layer 1041a and the second adhesive layer 1041b. Thus, the metal mesh formed on the first transparent dielectric substrate 1010a may be electrically connected to the feeding pattern formed on the second dielectric substrate 1010b.

[0169] The second dielectric substrate 1010b may be formed with a feeding structure 1100f having a second conductive pattern 1120 on one side and a third conductive pattern 1130 on the other side. The feeding structure 1100f may be implemented by a flexible printed circuit board (Flexible Printed Circuit Board), but is not limited thereto. A first protective layer 1033 may be disposed on the upper portion of the third conductive pattern 1130, and a second protective layer 1034 may be disposed on the lower portion of the second conductive pattern 1120. The adhesive layer 1041b at the lower portion of the third conductive pattern 1130 may be bonded to the adhesive layer 1041a of the antenna module 1100. Thus, the feeding structure 1100f may be combined with the antenna module 1100, and the first conductive pattern 1110 and the second conductive pattern 1120 may be electrically connected.

[0170] The thickness of the antenna module 1100 implemented by the first transparent dielectric substrate 1010a can be formed with a first thickness. The thickness of the feed structure 1100f implemented by the second dielectric substrate 1010b can be formed with a second thickness. For example, the thickness of the dielectric substrate 1010a of the antenna module 1100 can be 75um, the thickness of the first conductive pattern 1110 can be 9um, and the thickness of the protective layer 1031 can be 25um. The first thickness of the antenna module 1100 can be 109um. The thickness of the second dielectric substrate 1010b of the feed structure 1100f can be 50um, the thickness of the second conductive pattern 1120 can be 18um, the thickness of the third conductive pattern 1130 can be 18um, and the thickness of the first protective layer 1033 and the second protective layer 1034 can be 28um. Thus, the second thickness of the feed structure 1100f can be 142um. Since the adhesive layer 1041a is formed on the upper portion of the first conductive pattern 1110 and the adhesive layer 1041b is formed on the lower portion of the second conductive pattern 1120, the entire antenna assembly can be formed with a thickness less than the sum of the first thickness and the second thickness. For example, the thickness of the antenna assembly 1000 including the antenna module 1100 and the feeding structure 1100f can be 198 um.

[0171] Reference Figure 8b (b), a conductive pattern 1120 may be formed on one side of the second dielectric substrate 1010b forming the feeding structure 1100f. The conductive pattern 1120 may be formed in a feeding structure having a CPW (co-planar waveguide) structure having a feeding pattern 1120f and ground patterns 1121g and 1122g formed on both sides. Figure 8b (a), the feeding structure 1100f may be combined with the antenna module 1100 using the region where the adhesive layer 1041 is formed.

[0172] The antenna module and the feeding structure constituting the antenna assembly of this specification can be configured on the vehicle glass and combined through a specific combination structure. Figure 9a The figure shows the bonding structure of the transparent antenna disposed in the transparent area and the frit area of ​​the vehicle glass.

[0173] Reference Figure 9a, the first transparent dielectric substrate 1010a can be bonded to the glass panel 310 using an adhesive layer 1041. The conductive pattern of the first transparent dielectric substrate 1010a can be bonded to the conductive pattern 1130 of the second dielectric substrate 1010b by ACF bonding. ACF bonding is a method of bonding the bonding surface for several seconds using an adhesive tape with metal balls added under high temperature / high pressure conditions (e.g., 120-150 degrees, 2-5 MPa), which can be achieved by contacting the electrodes with metal balls. ACF bonding electrically connects the conductive pattern while curing the adhesive layer 1041 due to heat to provide bonding force.

[0174] The first transparent dielectric substrate 1010a formed with a transparent electrode layer can be attached to the second dielectric substrate 1010b in the form of an FPCB by using a local soldering technology. The connection pattern of the FPCB and the transparent antenna electrode can be connected by local soldering based on a coil in a magnetic field induction manner. During such local soldering, the temperature of the soldering portion does not rise, or the FPCB does not deform and can maintain a flat surface. Thus, by local soldering between the conductive patterns of the first transparent dielectric substrate 1010a and the second dielectric substrate 1010b, a highly reliable electrical connection can be achieved.

[0175] The first transparent dielectric substrate 1010a, Figure 7a The metal mesh layer 1020, the protective layer 1033 and the adhesive layer 1041 can form a transparent electrode. The second dielectric substrate 1010b as an opaque substrate can be implemented by an FPCB, but is not limited thereto. It can be configured such that the second dielectric substrate 1010b as an FPCB formed with a feeding pattern is connected to the connector part 313 and the transparent electrode.

[0176] The second dielectric substrate 1010b as an opaque substrate may be attached to a portion of the first transparent dielectric substrate 1010a. The first transparent dielectric substrate 1010a may be formed in the transparent region 311 of the glass panel 310. The second dielectric substrate 1010b may be formed in the opaque region 312 of the glass panel 310. A portion of the first transparent dielectric substrate 1010a may be formed in the opaque region 312, and the first transparent dielectric substrate 1010a may be combined with the second dielectric substrate 1010b in the opaque region 312.

[0177] The first transparent dielectric substrate 1010a and the second dielectric substrate 1010b may be bonded by bonding between the adhesive layers 1041a and 1041b. The position where the second dielectric substrate 1010b is bonded to the adhesive layer 1041 may be set as the first position P1. The position where the connector component 313 is welded to the opaque substrate 1010b may be set as the second position P2.

[0178] On the other hand, the vehicle glass formed with the antenna assembly of the present specification can be combined with the main structure of the vehicle. In this regard, Figure 9b It will form Figure 9a A magnified front view of the area where the transparent antenna glass is combined with the main structure of the vehicle. Fig.9c Indicates observation from different positions Figure 9b A cross-sectional view of the combined structure of vehicle glass and main structure.

[0179] Reference Figure 9b A first transparent dielectric substrate 1010a having a transparent antenna formed thereon may be disposed in a transparent region 311 of the glass panel 310. A second dielectric substrate 1010b may be disposed in an opaque region 312 of the glass panel 310. Since the transmittance of the opaque region 312 is lower than the transmittance of the transparent region 311, the opaque region 312 may also be referred to as a BM (Black Matrix) region. A portion of the first transparent dielectric substrate 1010a having a transparent antenna formed thereon may be extended to the opaque region 312 corresponding to the BM region. The first transparent dielectric substrate 1010a and the opaque region 312 may be formed to overlap along a single axis direction by an overlap length OL.

[0180] Fig.9c (a) indicates along Figure 9b A cross-sectional view of the antenna assembly taken along line AB. Fig.9c (a) indicates along Figure 9b A cross-sectional view of the antenna assembly taken along line CD.

[0181] Reference Figure 9b and Fig.9c (a), a first transparent dielectric substrate 1010a having a transparent antenna formed thereon may be disposed in a transparent region 311 of a glass panel 310. A second dielectric substrate 1010b may be disposed in an opaque region 312 of the glass panel 310. A portion of the first transparent dielectric substrate 1010a may be extended to the opaque region 312, so that a feeding pattern formed on the second dielectric substrate 1010b and a metal mesh layer of the transparent antenna can be joined and connected.

[0182] The interior cover 49c may be configured to accommodate a connector component 313 connected to the second dielectric substrate 1010b. The connector component 313 may be disposed in a space between the main body 49b of the metal material and the interior cover 49c, and the connector component 313 may be coupled to an in-vehicle cable. The interior cover 49c may be disposed in an upper region of the main body 49b of the metal material. One end of the interior cover 49c may be bent to be coupled to the main body 49b of the metal material.

[0183] The inner cover 49c may be formed of a metal material or a dielectric material. In the case where the inner cover 49c is formed of a metal material, the inner cover 49c and the main body 49b of the metal material form a metal frame 49. In this regard, the vehicle may include the metal frame 49. The opaque region 312 of the glass panel 310 may be supported by a portion of the metal frame 49. To this end, a portion of the main body 49b of the metal frame 49 may be bent so as to be combined with the opaque region 312 of the glass panel 310.

[0184] When the inner cover 49c is formed of a metal material, at least a portion of the metal region may be removed from the upper region of the second dielectric substrate 1010b in the inner cover 49c. A recess portion 49R where the metal region is removed may be formed in the inner cover 49c. Thus, the metal frame 49 may include the recess portion 49R. The second dielectric substrate 1010b may be disposed in the recess portion 49R of the metal frame 49.

[0185] The recess 49R may also be referred to as a metal cut region. One side of the recess 49R may be separated from one side of the opaque substrate 1010b by a first length L1 equal to or greater than a critical value. The lower boundary side of the recess 49R may be separated from the lower boundary side of the opaque substrate 1010b by a second length L2 equal to or greater than a critical value. As the metal of a portion of the inner cover 49c of the metal material is removed, signal loss and changes in antenna characteristics caused by the surrounding metal structure can be prevented.

[0186] Reference Figure 9b and Fig.9c (b), the area where the connector components and the opaque substrate are not configured can be configured so that the inner cover 49c does not form a recessed portion such as a metal removal area. In this regard, not only can the inner cover 49c protect the internal components of the antenna module 1100, but also can be used to Figure 9b and Fig.9cThe recess 49R of (a) discharges the internal heat to the outside. In addition, the recess 49R of the internal cover 49c can immediately determine whether the connection part needs to be repaired or replaced. On the other hand, since the internal cover 49c does not form a recess in the area where the connector component and the second dielectric substrate are not configured, the internal components of the antenna module 1100 can be protected.

[0187] On the other hand, the antenna assembly 1000 of the present specification can be formed in various forms on the glass panel 310, and the glass panel 310 can be attached to the vehicle frame. Fig.10 2 is a diagram showing a stacked structure of an antenna assembly according to an embodiment and attachment areas to a vehicle glass and a vehicle frame.

[0188] Reference Fig.10 (a), the glass panel 310 may include a transparent area 311 and an opaque area 312. The antenna assembly 1000 may include an antenna module 1100 and a feed structure 1100f. The antenna module 1100 may include a first transparent dielectric substrate 1010a, a transparent electrode layer 1020, and an adhesive layer 1041. The feed structure 1100f implemented by the opaque substrate and the transparent electrode layer 1020 implemented by the transparent substrate may be electrically connected. The feed structure 1100f and the transparent electrode layer 1020 may be directly connected through the first bonding area BR1. The feed structure 1100f and the connector component 313 may be directly connected through the second bonding area BR2. In order to bond, heat may be applied to the first bonding area BR1 and the second bonding area BR2. Thus, the bonding areas BR1 and BR2 may be referred to as heating intervals. In the side end area in the opaque area 312 of the glass panel 310, an attachment area AR equivalent to a sealant area for attaching the glass panel 310 and the vehicle frame may be formed.

[0189] Reference Fig.10(b), the glass panel 310 may include a transparent area 311 and an opaque area 312. The antenna assembly 1000 may include an antenna module 1100 and a feed structure 1100f. The antenna module 1100 may include a protective layer 1031, a transparent electrode layer 1020, a first transparent dielectric substrate 1010a, and an adhesive layer 1041. The feed structure 1100f implemented by the opaque substrate and a portion of the antenna module 1100 implemented by the transparent substrate may overlap. The feed structure 1100f and the transparent electrode layer 1020 of the antenna module 1100 may be coupled feed. The feed structure 1100f and the connector component 313 may be directly connected via a bonding area BR. For bonding, heat may be applied to the bonding area BR1. Thus, the bonding area BR may be referred to as a heating interval. In the side end area in the opaque area 312 of the glass panel 310, an attachment area AR equivalent to a sealant area for attaching the glass panel 310 and the vehicle frame may be formed.

[0190] Reference Fig.10 (a) and Fig.10 (b), the transparent substrate 1010a may include a (hard) coating layer to protect the transparent electrode layer 1020 from the external environment. On the other hand, the adhesive layer 1041 may be added with a UV blocking component to prevent yellowing due to sunlight.

[0191] Hereinafter, a vehicle having an antenna assembly that can be attached to a vehicle glass according to the present specification will be described with reference to the accompanying drawings. Fig.11 A front view of an antenna assembly that can be attached to a vehicle glass is shown in this specification. Fig.12a express Fig.11 The antenna assembly is configured on a rear glass structure configured with a plurality of heat line patterns.

[0192] Reference Figure 9a , Fig.11 as well as Fig.12a , the vehicle may include a glass panel 310 and an antenna assembly 1000. The antenna assembly 1000 may be configured on the glass panel 310.

[0193] The first region 1100a may include an antenna element 1100, which includes a conductive pattern on one side of a dielectric substrate 1010 and is configured to radiate a wireless signal. The second region 1100b may include a ground conductive pattern 1110g and a feed pattern 1110f. The first region 1100a may also be referred to as a radiator region, and the second region 1100b may be referred to as a ground region (or a feed region).

[0194] The antenna element 1100 may be configured to include a plurality of antenna structures, and may also be referred to as an antenna module 1100. The antenna element 1100 may include a first radiation structure 1100-1 and a second radiation structure 1100-2.

[0195] The first radiation structure 1100-1 and the second radiation structure 1100-2 formed in the first area 1100a of the antenna assembly 1000 can be respectively implemented by more than two conductive patterns and operate in multiple frequency bands. The multiple conductive patterns formed in the first area 1100a may include a first conductive pattern 1110 and a third conductive pattern 1130. The multiple conductive patterns may also include a first conductive pattern 1110, a second conductive pattern 1120, and a third conductive pattern 1130.

[0196] The first radiation structure 1100-1 may include a first conductive pattern 1110, a second conductive pattern 1120, and a third conductive pattern 1130. The first conductive pattern 1110 may be composed of a plurality of sub-patterns, i.e., a plurality of conductive portions. The first conductive pattern 1110 may include a first portion 1111 and a second portion 1112. The first portion 1111 may be formed to be perpendicular to the second portion 1112. The second portion 1112 may be electrically connected to the feed pattern 1110f. In this regard, "electrical connection" may include direct connection of the conductive portions or coupling at a predetermined interval.

[0197] The second conductive pattern 1120 may be disposed on a side region or a lower region of the first conductive pattern 1110. The second conductive pattern 1120 may be electrically connected to the first portion 1111g of the ground conductive pattern 1110g. By further configuring the second conductive pattern 1120 in the antenna assembly 1000, resonance may be achieved in a frequency band different from the operating frequency bands of the first conductive pattern 1110 and the third conductive pattern 1130.

[0198] The third conductive pattern 1130 may be disposed on the other side of the first conductive pattern 1110. The third conductive pattern 1130 may be electrically connected to the second portion 1112g of the ground conductive pattern 1110g. The size of the second conductive pattern 1120 may be smaller than that of the third conductive pattern 1130. Thus, through the second conductive pattern 1120, the antenna assembly 1000 may act as a radiator in a higher frequency band.

[0199] The second conductive pattern 1120 may be disposed between the first portion 1111 of the first conductive pattern 1110 and the first ground conductive pattern 1110g. The second conductive pattern 1120 may be disposed between the first portion 1111 of the first conductive pattern 1110 and the second portion 1112 of the first conductive pattern 1110. Thus, the second conductive pattern 1120 is disposed in the lower region of the first conductive pattern 1110, which can reduce the size of the antenna assembly 1000 compared to the case where the second conductive pattern 1120 is disposed in a region on one side of the first conductive pattern 1110. The first portion 1111 of the first conductive pattern 1110 and the third conductive pattern 1130 may be disposed on opposite sides with respect to the second portion 1112 of the first conductive pattern 1110. The first portion 1111 of the first conductive pattern 1110 and the third conductive pattern 1130 may be disposed in a region on one side and a region on the other side with respect to the second portion 1112 of the first conductive pattern 1110.

[0200] The second radiation structure 1100-2 may include a fourth conductive pattern 1140, a fifth conductive pattern 1150, and a third conductive pattern 1160. The fourth conductive pattern 1140 may be composed of a plurality of sub-patterns, i.e., a plurality of conductive portions. The fourth conductive pattern 1140 may include a third portion 1141 and a fourth portion 1142. The third portion 1141 may be formed to be perpendicular to the fourth portion 1142, and the fourth portion 1142 may be electrically connected to the feed pattern 1110f. In this regard, "electrical connection" may include direct connection of the respective conductive portions or coupling at a predetermined interval.

[0201] The fifth conductive pattern 1150 may be disposed on a side region or a lower region of the fourth conductive pattern 1140. The fifth conductive pattern 1150 may be electrically connected to the first portion 1121g of the second ground conductive pattern 1120g. By further configuring the fifth conductive pattern 1150 in the antenna assembly 1000, resonance may be performed in a frequency band different from the operating frequency bands of the fourth conductive pattern 1140 and the sixth conductive pattern 1160.

[0202] The sixth conductive pattern 1160 may be disposed on the other side of the fourth conductive pattern 1140. The sixth conductive pattern 1160 may be electrically connected to the second portion 1122g of the second ground conductive pattern 1120g. The size of the fifth conductive pattern 1150 may be smaller than that of the sixth conductive pattern 1160. Thus, through the fifth conductive pattern 1150, the antenna assembly 1000 may operate as a radiator at a higher frequency band.

[0203] The fifth conductive pattern 1150 may be disposed between the third portion 1141 of the fourth conductive pattern 1140 and the second ground conductive pattern 1120g. The fifth conductive pattern 1150 may be disposed between the third portion 1141 of the fourth conductive pattern 1140 and the fourth portion 1142 of the fourth conductive pattern 1140. Thus, the fifth conductive pattern 1150 is disposed in the lower region of the fourth conductive pattern 1140, which can reduce the size of the antenna assembly 1000 compared to the case where the fifth conductive pattern 1150 is disposed in the region on one side of the fourth conductive pattern 1140. The third portion 1141 of the fourth conductive pattern 1140 and the sixth conductive pattern 1160 may be disposed on the opposite side with respect to the fourth portion 1142 of the fourth conductive pattern 1140. The third portion 1141 of the fourth conductive pattern 1140 and the sixth conductive pattern 1160 may be disposed in the region on one side and the region on the other side with respect to the fourth portion 1142 of the fourth conductive pattern 1140.

[0204] The first radiation structure 1100-1 and the second radiation structure 1100-2 may be formed in a symmetrical structure with one axis as the center. In this regard, the third conductive pattern 1130 of the first radiation structure 1100-1 may be configured to face the sixth conductive pattern 1160 of the second radiation structure 1100-2. The first conductive pattern 1110 and the fourth conductive pattern 1140 may be separated by a predetermined distance or more through the third conductive pattern 1130 and the sixth conductive pattern 1160 connected to the ground conductive patterns 1110g and 1120g. In addition, the second conductive pattern 1120 and the fifth conductive pattern 1150 may be separated by a predetermined distance or more through the third conductive pattern 1130 and the sixth conductive pattern 1160 connected to the ground conductive patterns 1110g and 1120g.

[0205] By configuring the third conductive pattern 1130 and the sixth conductive pattern 1160 as a facing structure, the isolation between the first conductive pattern 1110 and the fourth conductive pattern 1140 operating in the monopole antenna mode can be improved in the second frequency band. In addition, by configuring the third conductive pattern 1130 and the sixth conductive pattern 1160 as a facing structure, the isolation between the second conductive pattern 1120 and the fifth conductive pattern 1150 can be improved in the third frequency band.

[0206] The first radiation structure 1100-1 and the second radiation structure 1100-2 can be configured to perform multiple input multiple output (MIMO). By configuring the third conductive pattern 1130 and the sixth conductive pattern 1160 as a facing structure, the isolation between the first radiation structure 1100-1 and the second radiation structure 1100-2 can be improved in the second frequency band and the third frequency band. By the asymmetric structure of the first conductive pattern 1110 and the third conductive pattern 1130, and the asymmetric structure of the fourth conductive pattern 1140 and the fifth conductive pattern 1160, the isolation between the first radiation structure 1100-1 and the second radiation structure 1100-2 can also be improved in the first frequency band.

[0207] On the other hand, the antenna assembly of the present specification can be configured on a vehicle glass configured with a plurality of heat line patterns. Referring to FIG. 12 , a plurality of heat line patterns 360 can be configured on the rear glass 330 at predetermined intervals along one axis direction or another axis direction. The antenna assembly 1000 can be configured in the lower area of ​​the rear glass 330, but is not limited thereto. Figure 1 As shown, the antenna assembly 1000 can be configured in at least one specific area of ​​the front glass 310 , the side glass 320 , the door glass 320 , the rear glass 330 , the corner window glass 340 , and the upper glass 350 .

[0208] The antenna component 1000 can be configured to be separated from the heat line pattern 360a in the lower area of ​​the plurality of heat line patterns 360 by a distance equivalent to the first gap G1 (G1=a) along one axis direction. The antenna component 1000 can be configured to be separated from the heat line patterns in one side area and the other side area of ​​the plurality of heat line patterns 360 by a distance equivalent to the prescribed interval b along another axis direction. In addition, the first radiation structure 1100-1 and the second radiation structure 1100-2 of the antenna component 1000 can be separated in another direction by a distance equivalent to the second gap G2. Thus, the third conductive pattern 1130 and the sixth conductive pattern 1160 can be separated by a distance equivalent to the second gap G2. In this regard, the third conductive pattern 1130 can be separated from the sixth conductive pattern 1160 by a minimum of 31 mm (0.12λg, @600MHz) or more.

[0209] One end and the other end of the heating wire pattern 360b in the upper region of the plurality of heating wire patterns 360 may be connected to the heating wire connector 363. Thus, the plurality of heating wire patterns 360 may be operably combined with a control unit that controls the heating wire of the vehicle.

[0210] Reference Figure 9a , Fig.11 as well as Fig.12a, the glass panel 310 may include a plurality of heat line patterns 360. One of the plurality of heat line patterns 360 may be spaced apart from the antenna element 1100 by a distance corresponding to the first gap G1. The third conductive pattern 1130 may be configured to be spaced apart from the sixth conductive pattern by a distance corresponding to the second gap G2.

[0211] The length of the first region 1100a as the radiator region constituting the antenna assembly 1000 on one axis and the other axis may be longer than the length of the second region 1100b as the feed region on one axis and the other axis. In this regard, the horizontal length of the first ground conductive pattern 1110g may be less than the horizontal length from the first conductive pattern 1110 to the fourth conductive pattern 1140. The vertical length of the first ground conductive pattern may be less than the vertical length starting from the first conductive pattern 1110. The area of ​​the second dielectric substrate 1010b formed with the ground conductive patterns 1110g and 1120g is smaller than the area of ​​the first dielectric substrate 1010a formed with the conductive patterns (1110 to 1130, 1140 to 1160). The vertical length starting from the first conductive pattern 1110 may be 35.6 mm. The vertical length of the antenna assembly 1000 configured in the transparent region 311 and the opaque region 312 may be 55.8 mm. The vertical length of the first ground conductive pattern may be 55.8-35.6=20.2 mm.

[0212] On the other hand, the areas of the third conductive pattern 1130 and the sixth conductive pattern 1160 connected to the ground conductive patterns 1110g and 1120g may be greater than the areas of the first conductive pattern 1110 and the fourth conductive pattern 1140 connected to the feed patterns 1110f and 1120g at a prescribed ratio. In this regard, both the upper and lower regions of the first conductive pattern 1110 and the fourth conductive pattern 1140 may be formed in a stepped structure. On the contrary, the third conductive pattern 1130 and the sixth conductive pattern 1160 may be formed in a stepped structure in only one of the upper and lower regions.

[0213] The areas of the third conductive pattern 1130 and the sixth conductive pattern 1160 may be greater than the areas of the first conductive pattern 1110 and the fourth conductive pattern 1140 by more than 10%. For example, the areas of the third conductive pattern 1130 and the sixth conductive pattern 1160 may be 1640 mm 2 The area of ​​the first conductive pattern 1110 and the fourth conductive pattern 1140 may be 1445 mm 2 On the other hand, the area of ​​the second conductive pattern 1120 and the fifth conductive pattern 1150 connected to the ground conductive patterns 1110g and 1120g may be 58 mm 2 .

[0214] On the other hand, the antenna assembly of the present specification can be configured on a vehicle glass configured with a plurality of heat line patterns. Referring to FIG. 12 , a plurality of heat line patterns 360 can be configured on the rear glass 330 at predetermined intervals along one axis direction or another axis direction. The antenna assembly 1000 can be configured in the lower area of ​​the rear glass 330, but is not limited thereto. Figure 1 As shown, the antenna assembly 1000 can be configured in at least one specific area of ​​the front glass 310 , the side glass 320 , the door glass 320 , the rear glass 330 , the corner window glass 340 , and the upper glass 350 .

[0215] The antenna assembly 1000 may be spaced apart from the heat wire pattern 360a in the lower region of the plurality of heat wire patterns 360 by a distance corresponding to the first gap G1 along one axis direction. The antenna assembly 1000 may be spaced apart from the heat wire pattern 360 in the lower region of the plurality of heat wire patterns 360 by a distance corresponding to the second gap G2 along another axis direction. One end and the other end of the heat wire pattern 360b in the upper region of the plurality of heat wire patterns 360 may be connected to the heat wire connector 363. Thus, the plurality of heat wire patterns 360 may be operably combined with a control unit that controls the heat wires of the vehicle.

[0216] Reference Figure 9a , Fig.11 as well as Fig.12a , the glass panel 310 may include a plurality of heat line patterns 360. Compared to the first dielectric substrate 1000 formed by the transparent antenna, the plurality of heat line patterns 360 may be formed with a sufficiently large size above a specified ratio. In this regard, the plurality of heat line patterns 360 may be formed with a size greater than a first size along the horizontal axis direction and with a size greater than a second size along the vertical axis direction. The value of the first size in the horizontal axis direction may be set to be greater than the value of the second size in the vertical axis direction. Based on 600MHz, the lowest frequency in the antenna operating frequency, the first size in the horizontal axis direction may be greater than 3λg, which is 3 wavelengths. The second size in the vertical axis direction may be greater than 1.5λg, which is 1.5 wavelengths. In this regard, the dielectric constant of the glass panel 310 may be set to approximately 6.7, but is not limited thereto.

[0217] One of the plurality of heating line patterns 360 may be configured to be spaced apart from the antenna element along one axis by a distance corresponding to the first gap G1 (G1=a). The third conductive pattern 1130 may be configured to be spaced apart from the sixth conductive pattern by a distance corresponding to the second gap G2. On the other hand, the plurality of heating line patterns 360 may be formed to be spaced apart from one end and the other end of the antenna assembly 1000 along another axis by a distance corresponding to a predetermined interval b.

[0218] As mentioned above, the heating line pattern 360 and the conductive pattern in the antenna assembly 1000 need to be separated by a predetermined interval, namely, the first gap G1. Figure 12b This is the antenna efficiency characteristic under various frequency conditions that varies according to the distance between the heating line pattern and the conductive pattern in the antenna element.

[0219] Reference Fig.11 and Fig.12a , the third conductive pattern 1130 and the sixth conductive pattern 1160 may be formed to the upper end of the antenna assembly 1000. Thus, the interval between the heating line pattern 360 and the conductive pattern in the antenna assembly 1000 corresponds to the first gap G1 which is the interval from the upper end of the antenna assembly 1000 to the lower end of the plurality of heating line patterns 360.

[0220] Reference Figure 11 to Figure 12b The first gap G1 from the upper end of the antenna assembly 1000 to the lower end of the plurality of heating line patterns 360 is denoted as a. On the other hand, the intervals from one end and the other end of the antenna assembly 1000 to the plurality of heating line patterns 360 in the other axial direction are denoted as b.

[0221] Reference Figure 12b It can be seen that in the low frequency band (LB) for 4G / 5G wireless communication, the antenna efficiency has the maximum value when a=100 is set. In this regard, the interval from one end and the other end of the antenna assembly 1000 to the other axial direction of the plurality of heat line patterns 360 is set to b=50 mm.

[0222] Therefore, the heating wire pattern 360 and the antenna element need to be spaced at least a certain distance. In this regard, the heating wire pattern 360 needs to be spaced at a distance of a=100 mm or more based on the upper end of the antenna assembly 1000, and at a distance of b=50 mm or more based on the ends of one side and the other side. Compared with a structure in which no heating wire pattern is formed, a structure in which the heating wire pattern 360 is arranged at a distance of a=100 mm has a higher antenna efficiency characteristic under low frequency band (LB) conditions.

[0223] Thus, the radiation pattern for low elevation can be improved without changing the antenna efficiency. In this regard, the conductor structure formed by the hot wire pattern 360 can improve the desired interval, such as the radiation component at low elevation, by reflecting the beam formed by the antenna element. Thus, the radiation pattern component in the upper direction of the vehicle is formed in the lower direction, thereby increasing the low elevation gain of the antenna module.

[0224] On the other hand, when the antenna assembly of the present specification is arranged on the vehicle glass, the form of the antenna radiation pattern can be changed according to the heat line pattern. Fig.13a It is relatively Fig.11 The antenna assembly is configured in the structure of the rear glass of the vehicle, and the radiation pattern changes depending on whether a hot line pattern is configured. Fig.13b The diagram compares low elevation radiation patterns when a heat line pattern is formed when the antenna assembly is disposed on the rear glass of a vehicle.

[0225] Reference Fig.11 , Fig.12a as well as Fig.13a , a hot wire pattern 360 may be formed in an upper area of ​​the rear glass 330 of the vehicle 500. An antenna assembly 1000 with a transparent antenna structure may be formed in a lower area of ​​the hot wire pattern 360. A TCU 300 may be configured at the lower portion of the antenna assembly 1000 with a transparent antenna structure. When a hot wire pattern is not configured on the rear glass 330, the first radiation pattern RP1 has a peak at a first angle in the elevation angle direction. On the other hand, if a hot wire pattern is configured on the rear glass 330, the second radiation pattern RP2 has a peak at a second angle θ2 that is smaller than the first angle θ1 in the elevation angle direction. Thus, as a hot wire pattern is configured on the rear glass 330, the second radiation pattern RP2 has a low elevation characteristic in which the difference Δθ from the beam peak angle of the first radiation pattern RP1 is equivalent to θ1-θ2.

[0226] Reference Fig.13b , is to compare the low elevation characteristics of a specified angle range toward the back of the vehicle based on whether there is a heat pattern. In this regard, stable wireless communication can only be carried out through the vehicle if the level of the radiation pattern within a range of about 30 degrees toward the front and back of the vehicle reaches a specified level or above. For this reason, Fig.11 , Fig.12a as well as Fig.13a , the heat line pattern 360 needs to be arranged in the upper area of ​​the antenna assembly 1000. Thus, the rear direction of the vehicle can be realized as follows Fig.11 c shows the low elevation beam characteristics within a specified angle range.

[0227] Fig.13b(a) is a diagram showing a first radiation pattern RP1 when an antenna assembly is formed on a rear glass without a heat line pattern. The first radiation pattern RP1 has a value less than a reference value within a predetermined angle range with respect to a horizontal plane. The first radiation pattern RP1 has a value less than -7.5 dBi within a range of 30 degrees with respect to a horizontal plane. Fig.13b (b) shows the second radiation pattern RP2 when the antenna assembly is formed on the rear glass with the heat line pattern. The second radiation pattern RP2 has a value greater than the reference value within a specified angle range based on the horizontal plane. The second radiation pattern RP2 has a value greater than -7.5dBi within a range of 30 degrees based on the horizontal plane.

[0228] The antenna assembly of the present specification is capable of broadband operation so as to be able to perform 4G wireless communication and 5G wireless communication. In addition, the antenna assembly of the present specification can reduce interference between antenna elements during multiple input multiple output (MIMO) operation by operating in a dipole antenna mode. In this regard, Fig.14a This is a diagram comparing the radiation patterns of a monopole antenna operating in a single frequency band and the antenna assembly of this specification. Fig.14b It is a comparison Fig.14a A diagram of the gain characteristics of the monopole antenna and the gain characteristics of the antenna assembly of the present specification.

[0229] Reference Fig.14a (a) The radiation patterns RP1a and RP2a of the monopole antennas 1100-1 and 1100-2 are formed in a direction parallel to the antenna element. That is, the radiation patterns are formed in one direction and the other direction of the antenna element. Therefore, when the monopole antenna 1100a is configured to be spaced apart for MIMO operation, interference may occur between the antenna elements.

[0230] On the contrary, refer to Fig.14a (b), the radiation patterns RP1 and RP2 of the antenna assembly 1000 can be formed in a direction perpendicular to the antenna arrangement. That is, the radiation patterns are formed in the upper direction and the lower direction of the antenna element. Thus, even when the antenna assembly 1000 is configured to be separated for MIMO operation, the interference between the antenna elements can be minimized to below a predetermined level.

[0231] Reference Fig.14a (a) and Fig.14b (a) of the present invention, the monopole antennas 1100-1 and 1100-2 operate to resonate in a single frequency band. The monopole antennas 1100-1 and 1100-2 operate as radiators only in a specified frequency band based on the center frequency f1. Therefore, the entire frequency band used for 4G / 5G wireless communications cannot be covered.

[0232] On the contrary, refer to Fig.14a (b) and Fig.14b (b), the antenna assembly 1000 operates to resonate in multiple frequency bands. The antenna assembly 1000 operates as a radiator in the first frequency band to the third frequency band based on multiple resonant frequencies, such as f1, f2 and f3. The antenna assembly 1000 can operate in a first mode in the first frequency band, in a second mode in the second frequency band, and in a third mode in the third frequency band. As a result, the antenna assembly 1000 can operate as a radiator in the low frequency band (LB: low band), the mid frequency band (MB: mid band), the high frequency band (HB: high band) and the 5G Sub6 frequency band used for 4G / 5G wireless communications.

[0233] To this end, each of the plurality of conductive patterns of the antenna assembly 1000 and their combination can act as a radiator in each frequency band. Figures 15a to 15c Yes means Fig.11 A conceptual diagram of the principle of operation of the antenna assembly 1000 in various frequency bands.

[0234] Reference Fig.11 , Fig.14b as well as Fig.15a , the antenna assembly 1000 can operate in a dipole antenna mode at 617 to 960 MHz as a first frequency band. The first frequency band is not limited thereto and can change according to the application for 4G / 5G LB communication. The first conductive pattern 1110 and the third conductive pattern 1130 of the first radiation structure 1100-1 can operate in a first dipole antenna mode in the first frequency band. The first conductive pattern 1110 and the third conductive pattern 1130 can form an asymmetrical structure. The fourth conductive pattern 1140 and the sixth conductive pattern 1160 of the second radiation structure 1100-2 can operate in a second dipole antenna mode in the first frequency band. The fourth conductive pattern 1140 and the sixth conductive pattern 1160 can form an asymmetrical structure.

[0235] In the first radiation structure 1100-1, the first conductive pattern 1110 may be formed in a stepped structure in which a plurality of conductive portions have different heights. The third conductive pattern 1130 may be formed in a straight line structure in which the upper end regions of the plurality of conductive portions are in a straight line form. The end of the lower end region of the third conductive pattern 1130 may be formed at different locations for impedance matching. In the second radiation structure 1100-2, the fourth conductive pattern 1140 may be formed in a stepped structure in which a plurality of conductive portions have different heights. The sixth conductive pattern 1160 may be formed in a straight line structure in which the upper end regions of the plurality of conductive portions are in a straight line form. The end of the lower end region of the sixth conductive pattern 1160 may be formed at different locations for impedance matching.

[0236] Reference Fig.11 , Fig.14b as well as Fig.15b , the antenna assembly 1000 can operate in a monopole antenna mode at 1520 to 4500 MHz as a second frequency band. In this regard, the second frequency band is a higher frequency than the first frequency band and can be changed according to the application for 4G / 5G MB / HB communication. The first conductive pattern 1110 of the first radiation structure 1100-1 can operate in a first monopole antenna mode in the second frequency band. The fourth conductive pattern 1140 of the second radiation structure 1100-2 can operate in a second monopole antenna mode in the second frequency band. In this regard, in the second frequency band, a first current I1b can be formed from the first portion 1111 of the first conductive pattern 1110 to the second portion 1112 of the first conductive pattern 1110. In addition, in the second frequency band, a second current I2b can be formed from the second portion 1112 of the first conductive pattern 1110 to the first portion 1111 of the first conductive pattern 1110. Therefore, in the second frequency band, the first conductive pattern 1110 can operate in a monopole antenna mode.

[0237] Since the second frequency band is set to a higher value than the first frequency band, even if the antenna is operated in the monopole antenna mode in the second frequency band, the interference between the plurality of antenna elements is smaller than that in the first frequency band. Thus, the antenna assembly 1000 operates in the dipole antenna mode in the first frequency band to prevent interference between the antenna elements. The antenna assembly 1000 operates in the monopole antenna mode in the second frequency band for broadband operation.

[0238] Reference Fig.11 , Fig.14b as well as Fig.15c , the antenna assembly 1000 can act as a radiator by additional resonance in the third frequency band of 4500 to 6000 MHz. In this regard, in the third frequency band, a third current I3 can be formed in the second conductive pattern 1120. In the third frequency band, a third current I3 can be formed in the second conductive pattern 1120. Thus, in the third frequency band, the third conductive pattern 1130 can act as a radiator.

[0239] In this regard, the third frequency band is a higher frequency than the second frequency band, and for 4G / 5G UHB and 5G Sub 6 communications, it can change according to the application. The second conductive pattern 1120 of the first radiation structure 1100-1 can act as a first radiator in the third frequency band. The fifth conductive pattern 1150 of the second radiation structure 1100-1 can act as a second radiator in the third frequency band. The third frequency band can be set to be higher than the second frequency band. Thus, in addition to the first frequency band and the second frequency band, the antenna assembly 1000 can also act as a radiator in the third frequency band, thereby being able to cover the entire frequency band for 4G / 5G wireless communications.

[0240] The first conductive pattern 1110 of the first radiation structure 1100-1 is combined with the third conductive pattern 1110 and operates in a first monopole antenna mode in a first frequency band, and operates in a second dipole antenna mode in an additional second frequency band. To this end, the shape of the first conductive pattern 1110 can be optimized into a stepped structure for broadband operation. In this regard, the first conductive pattern 1110 can be formed to have a plurality of boundary sides.

[0241] Similarly, the fourth conductive pattern 1140 of the second radiating structure 1100-2 is combined with the sixth conductive pattern 1160 and operates in the second monopole antenna mode in the first frequency band, and operates in the second dipole antenna mode in the additional second frequency band. To this end, the shape of the fourth conductive pattern 1140 can be optimized into a stepped structure for broadband operation. In this regard, the fourth conductive pattern 1140 can be formed to have a plurality of boundary sides. (Made to this)

[0242] The first portion 1111 of the first conductive pattern 1110 of the first radiation structure 1100-1 may be formed to have a plurality of boundary sides. The first portion 1111 of the first conductive pattern 1110 may be formed to have first to fourth boundary sides BS1 to BS4.

[0243] A first boundary side BS1 of the first portion 1111 of the first conductive pattern 1110 may be formed to have a first step structure. A second boundary side BS2 of the first portion 1111 of the first conductive pattern 1110 may be formed to have a second step structure. The second step structure may be formed in a different shape from the first step structure.

[0244] The third boundary side BS3 of the first portion 1111 of the first conductive pattern 1110 may be disposed between a first end of the first boundary side BS1 of the first portion 1111 of the first conductive pattern 1110 and a first end of the second boundary side BS2 of the first portion 1111 of the first conductive pattern 1110. The fourth boundary side BS4 of the first portion 1111 of the first conductive pattern 1110 may be disposed between a second end of the first boundary side BS1 of the first portion 1111 of the first conductive pattern 1110 and a second end of the second boundary side BS2 of the first portion 1111 of the first conductive pattern 1110. Thus, the shape of the first portion 1111 of the first conductive pattern 1110 may be optimized for broadband operation in the first frequency band and the second frequency band.

[0245] The second conductive pattern 1120 may also be formed to have a first boundary side BS1 and a second boundary side BS2. A portion of the first boundary side BS1 of the first portion 1111 of the first conductive pattern 1110 may be formed to face the first boundary side BS1 of the second conductive pattern 1120. A portion of the first boundary side BS1 of the first portion 1111 of the first conductive pattern 1110 may be formed to face the second boundary side BS2 of the second conductive pattern 1120.

[0246] The third conductive pattern 1130 may also be formed to have a plurality of boundary sides for a step structure. The third conductive pattern 1130 may be formed to have a first boundary side BS1 to a fourth boundary side BS4. The first boundary side BS1 of the third conductive pattern 1130 may be formed to have a third step structure. The first end of the first boundary side BS1 of the third conductive pattern 1130 may be connected to the second portion 1112g of the first ground conductive pattern 1110g. The second boundary side BS2 of the third conductive pattern 1130 may be arranged on the opposite side of the first boundary side BS1 of the third conductive pattern 1130.

[0247] The third boundary side BS3 of the third conductive pattern 1130 may be configured between a first end of the first boundary side BS1 of the third conductive pattern and a first end of the second boundary side BS2 of the third conductive pattern 1130. The fourth boundary side BS4 of the third conductive pattern 1130 may be configured between a second end of the first boundary side BS1 of the third conductive pattern 1130 and a second end of the second boundary side BS2 of the third conductive pattern 1130. The third boundary side BS3 of the third conductive pattern 1130 may be configured on the opposite side of the fourth boundary side BS4 of the third conductive pattern 1130. A portion of the second portion 1112 of the first conductive pattern 1110 may be formed to face the fourth boundary side BS4 of the third conductive pattern 1130.

[0248] The length of the third boundary side BS3 of the third conductive pattern 1130 may be the same as the length of the third boundary side BS3 of the first conductive pattern 1110. Thus, the antenna assembly 1000 may be formed with the length of the third boundary side BS3 of the first conductive pattern 1110 and the third conductive pattern 1130, which can minimize the size of the entire antenna.

[0249] Similar to the first radiation structure 1100-1, the second radiation structure 1100-1 may also be formed to have a plurality of boundary sides. The fourth conductive pattern 1140 to the sixth conductive pattern 1160 of the second radiation structure 1100-1 may also be formed to have a plurality of boundary sides. The third portion 1141 of the fourth conductive pattern 1140 may be formed to have a plurality of boundary sides. The third portion 1141 of the fourth conductive pattern 1140 may be formed to have a first boundary side BS1 to a fourth boundary side BS4.

[0250] A first boundary side BS1 of the third portion 1141 of the fourth conductive pattern 1140 may be formed to have a first step structure. A second boundary side BS2 of the third portion 1141 of the fourth conductive pattern 1140 may be formed to have a second step structure. The second step structure may be formed in a different shape from the first step structure.

[0251] The third boundary side BS3 of the third portion 1141 of the fourth conductive pattern 1140 may be disposed between a first end of the first boundary side BS1 of the third portion 1141 of the fourth conductive pattern 1140 and a first end of the second boundary side BS2 of the third portion 1141 of the fourth conductive pattern 1140. The fourth boundary side BS4 of the third portion 1141 of the fourth conductive pattern 1140 may be disposed between a second end of the first boundary side BS1 of the third portion 1141 of the fourth conductive pattern 1140 and a second end of the second boundary side BS2 of the third portion 1141 of the fourth conductive pattern 1140. Thus, the shape of the third portion 1141 of the fourth conductive pattern 1140 may be optimized for broadband operation in the first frequency band and the second frequency band.

[0252] The sixth conductive pattern 1160 may also be formed to have a first boundary side BS1 and a second boundary side BS2. A portion of the first boundary side BS1 of the third portion 1141 of the fourth conductive pattern 1140 may be formed to face the first boundary side BS1 of the fifth conductive pattern 1150. A portion of the first boundary side BS1 of the third portion 1141 of the fourth conductive pattern 1140 may be formed to face the second boundary side BS2 of the fifth conductive pattern 1150.

[0253] The sixth conductive pattern 1160 may also be formed to have a plurality of boundary sides for a step structure. The sixth conductive pattern 1160 may be formed to have a first boundary side BS1 to a fourth boundary side BS4. The first boundary side BS1 of the sixth conductive pattern 1160 may be formed to have a third step structure. The first end of the first boundary side BS1 of the sixth conductive pattern 1160 may be connected to the second portion 1112g of the second ground conductive pattern 1120g. The second boundary side BS2 of the sixth conductive pattern 1160 may be configured on the opposite side of the first boundary side BS1 of the sixth conductive pattern 1160.

[0254] The third boundary side BS3 of the sixth conductive pattern 1160 may be arranged between the first end of the first boundary side BS1 of the third conductive pattern and the first end of the second boundary side BS2 of the sixth conductive pattern 1160. The fourth boundary side BS4 of the sixth conductive pattern 1160 may be arranged between the second end of the first boundary side BS1 of the sixth conductive pattern 1160 and the second end of the second boundary side BS2 of the third conductive pattern 1130. The third boundary side BS3 of the sixth conductive pattern 1160 may be arranged on the opposite side of the fourth boundary side BS4 of the sixth conductive pattern 1160. A portion of the fourth portion 1142 of the fourth conductive pattern 1140 may be formed to face the fourth boundary side BS4 of the sixth conductive pattern 1160.

[0255] The length of the third boundary side BS3 of the sixth conductive pattern 1160 may be the same as the length of the third boundary side BS3 of the fourth conductive pattern 1140. Thus, the antenna assembly 1000 may be formed with the length of the third boundary side BS3 of the fourth conductive pattern 1140 and the sixth conductive pattern 1160, which can minimize the size of the entire antenna.

[0256] The conductive pattern of the antenna assembly of the present specification can be deformed in various shapes. In this regard, Fig.16a and Fig.16b This shows a structure in which the shape of the second conductive pattern and the shape of the third conductive pattern are changed.

[0257] Reference Fig.11 , a portion of the upper end of the second conductive pattern 1120 of the antenna assembly 1000 may be formed in a triangular shape. Fig.16a , the second conductive pattern 1120b of the antenna component 1000a can be configured in a quadrilateral shape. The second conductive pattern 1120b can be configured in a side area or a lower area of ​​the first conductive pattern 1110. The second conductive pattern 1120b can be electrically connected to the first portion 1111g of the ground conductive pattern 1110g. Through the second conductive pattern 1120b, the antenna component 1000 can operate as a radiator in the third frequency band. In this regard, through the second conductive pattern 1120, the antenna component 1000 can also operate as a radiator in the third frequency band. A portion of the impedance matching characteristics under the third frequency band condition can change as the shape of the second conductive pattern 1120b changes.

[0258] The size of the second conductive pattern 1120b may be smaller than that of the third conductive pattern 1130. Thus, the antenna assembly 1000 may operate as a radiator in the third frequency band, which is a higher frequency band, through the second conductive pattern 1120b. The second conductive pattern 1120b may be disposed between the first portion 1111 of the first conductive pattern 1110 and the second portion 1112 of the first conductive pattern 1110. Thus, the second conductive pattern 1120b is disposed in the lower region of the first conductive pattern 1110, and the size of the antenna assembly 1000 can be reduced compared to the case where the second conductive pattern 1120b is disposed in the region on one side of the first conductive pattern 1110.

[0259] Reference Fig.16b , the third conductive pattern 1130b of the antenna assembly 1000b may be formed in a symmetrical structure with the first conductive pattern 1110. Similar to the first conductive pattern 1110, the third conductive pattern 1130b may also be configured to include a first portion 1131 and a second portion 1132. Similar to the first conductive pattern 1110, the third conductive pattern 1130b may also be formed such that the upper end portion and the lower end portion are each formed in a stepped structure. Fig.11 The third conductive pattern 1130 of b can be Figure 12b The size of the third conductive pattern 1130b is formed to be larger in size.

[0260] On the other hand, the conductive pattern of the antenna assembly of the present specification may also be formed in a continuous structure instead of a stepped structure. Fig.16c Represents a structure in which the shapes of the first conductive pattern and the third conductive pattern are formed in a continuous structure.

[0261] Reference Fig.16c The antenna assembly 1000c may include a first conductive pattern 1110c, a second conductive pattern 1120, and a third conductive pattern 1130c. Each connection portion of the first conductive pattern 1110c may be formed in a continuous connection structure. Each connection portion of the third conductive pattern 1130c may also be formed in a continuous connection structure.

[0262] Reference Fig.16a and Fig.16b , each connection part of the first conductive pattern 1110 can be formed in a vertical step structure. Thus, the first conductive pattern 1110 formed in a step structure can increase the current component in the vertical direction. Each connection part of the third conductive patterns 1130 and 1130b can be formed in a vertical step structure. Thus, the third conductive pattern 1110 formed in a step structure can increase the current component in the vertical direction.

[0263] Regarding this, Fig.17a It is a comparison Fig.11 and Fig.16c A plot of the reflection coefficient characteristics of an antenna assembly. Fig.17b It is a comparison Fig.11 and Fig.16c A graph of the antenna efficiency characteristics of an antenna assembly.

[0264] Reference Fig.11 , each connection portion of the first conductive pattern 1110 of the antenna assembly 1000 is formed in a vertical step structure, thereby increasing the vertical current component. Fig.16c , each connection portion of the first conductive pattern 1110 of the antenna assembly 1000c is formed in a continuous connection structure, thereby reducing the current component in the vertical direction. Fig.17a , in a frequency band above about 3 GHz, the reflection coefficient of (i) the antenna component 1000c formed in a continuous structure may be degraded compared to the reflection coefficient of (ii) the antenna component 1000 formed in a stepped structure.

[0265] Reference Fig.11 , each connection portion of the first conductive pattern 1110 of the antenna assembly 1000 is formed in a vertical step structure, thereby increasing the vertical current component. Fig.16c , each connection portion of the first conductive pattern 1110 of the antenna assembly 1000c is formed in a continuous connection structure, thereby reducing the current component in the vertical direction. Fig.17b , in the frequency band above about 1.5 GHz, the antenna efficiency of the antenna assembly 1000c (i) formed with a continuous structure may be degraded compared to the antenna efficiency of the antenna assembly 1000 (ii) formed with a stepped structure. In particular, at about 4 GHz, the antenna efficiency of the antenna assembly 1000c (i) formed with a continuous structure may be degraded by more than 0.3 dB compared to the antenna efficiency of the antenna assembly 1000 (ii) formed with a stepped structure. At about 5.5 GHz, the antenna efficiency of the antenna assembly 1000c (i) formed with a continuous structure may be degraded by more than 0.5 dB compared to the antenna efficiency of the antenna assembly 1000 (ii) formed with a stepped structure.

[0266] Below, by comparison Fig.16b The symmetrical structure of the antenna assembly 1000b and Fig.11 The electrical characteristics of the asymmetric antenna assembly 1000b are described. Fig.18a Yes means Fig.11 The antenna efficiency of the asymmetric structure antenna assembly and Fig.16b Plot of the antenna efficiency of the symmetrically structured antenna assembly. Fig.18b Yes means Fig.11 The electric field distribution of the asymmetric antenna component and Fig.16b Diagram of the electric field distribution of the antenna component with a symmetrical structure.

[0267] Reference Fig.16b and Fig.18a , (i) The antenna efficiency of the symmetrical structure antenna assembly 1000b has a value of about -4dBi in the frequency band above 3.5GHz. Fig.11 b and Fig.15a , (ii) The antenna efficiency of the antenna assembly 1000 with an asymmetric structure has a value of about -3dBi to -3.5dBi in the frequency band above 3.5GHz. Therefore, Fig.11 The antenna efficiency of the asymmetric structure antenna assembly 1000 is better than Figure 12b The antenna efficiency of the symmetrical structure of the antenna assembly 1000b is about 0.5 to 1.0 dB higher.

[0268] In the frequency band above about 3 GHz, the antenna efficiency of the asymmetric structure antenna assembly 1000 is about 0.5 to 1.0 dB higher than the antenna efficiency of the symmetric structure antenna assembly 1000b. Therefore, in the frequency band above about 3 GHz in the second frequency band and the third frequency band, the antenna efficiency of the asymmetric structure antenna assembly 1000 can be improved.

[0269] Fig.18b (a) means Fig.16b The electric field distribution of the antenna assembly 1000b with a symmetrical structure at 3.5 GHz is shown in FIG. Fig.18b (b) means Fig.11 FIG. 1 is a diagram of the electric field distribution of the asymmetric structure antenna assembly 1000 at 3.5 GHz.

[0270] Fig.11 The size of the third conductive pattern 1130 of the asymmetric structure of the antenna assembly 1000 can be larger than Fig.16b The size of the third conductive pattern 1130b is larger. Therefore, it is equivalent to increasing the grounding size of the monopole antenna through the third conductive pattern 1130 of the antenna component 1000 with an asymmetric structure that is larger than the third conductive pattern 1130b. As the size of the third conductive pattern 1130 of the antenna component 1000 with an asymmetric structure increases, the electric field radiation of the monopole antenna mode under the second frequency band condition increases.

[0271] Reference Fig.16b and Fig.18b (a), the peak area of ​​the electric field distribution appears in the first area R1p between the first conductive pattern 1100 and the third conductive pattern 1130, due to the third conductive pattern 1130 having a symmetrical structure with the first conductive pattern 1100. Fig.11 and Fig.18b(b), through the third conductive pattern 1130 that is larger than the first conductive pattern 1100, the peak area of ​​the electric field distribution appears in the second area R2p that is closer to the third conductive pattern 1130 than the first area R1p. In addition, as the size of the third conductive pattern 1130 of the asymmetric structure antenna component 1000 increases, the area of ​​the second area R2p, which is the peak area of ​​the electric field distribution, also increases compared with the area of ​​the first area Rp1. As a result, the antenna efficiency of the asymmetric structure antenna component 1000 can be improved in the frequency band above about 3 GHz and the third frequency band.

[0272] On the other hand, the ground conductive pattern 1110g of the second region 1100b of the antenna assembly 1100 of the present specification may have more than one slot for broadband impedance matching. Fig.19a The first slot structure and the second slot structure formed by the ground conductive pattern of the antenna assembly of this specification are shown. On the other hand, Fig.19b It means in Fig.19a A diagram of a first slot structure, a second slot structure, and current distribution around a ground conductive pattern formed by an antenna assembly.

[0273] Reference Fig.19a The first portion 1111g, 1121g of the second region 1100b corresponding to the ground region may include a first groove 1111s. The second portion 1112g, 1122g of the second region 1100b corresponding to the ground region may include a second groove 1112s.

[0274] The first ground conductive pattern 1110g may include a first groove 1111s and a second groove 1112s. The second ground conductive pattern 1120g may include a first groove 1111s and a second groove 1112s.

[0275] The first portion 1111g of the first ground conductive pattern 1110g may include a first slot 1111s. The first portion 1121g of the second ground conductive pattern 1120g may include a first slot 1111s. The length of the first slot 1111s may be formed with a length in the range of λ / 2 to λ based on about 5 GHz. An open region of the first slot 1111s may be formed to face the feed pattern 1110f. The second portion 1112g of the first ground conductive pattern 1110g may include a second slot 1112s. The second portion 1122g of the second ground conductive pattern 1120g may include a second slot 1112s. The length of the second slot 1112s may be formed with a length in the range of λ / 2 to λ based on about 5 GHz. The open region of the second slot 1112s may be formed to face the first region 1110a as a radiator region.

[0276] Reference Fig.19b It can be seen that the current distribution is concentrated around the feeding pattern 1110f and the first slot 1111s and the second slot 1112s formed on both sides of the feeding pattern 1110f. As a result, the impedance matching characteristics of the HB band and the UHB band, that is, the 3.5 to 6 GHz band, are improved, so that the antenna assembly can operate in a wideband.

[0277] On the other hand, the slot structure of the antenna assembly of this specification is not limited to a quadrilateral slot. In this regard, Fig.19c 2 is a diagram showing a circular slot structure of an antenna assembly of an embodiment. Fig.19c , a circular first groove 1111s2 may be formed in the first portion 1111g of the ground conductive pattern 1110g, and a circular second groove 1112s2 may be formed in the second portion 1112g of the ground conductive pattern 1110g. In this regard, the shapes of the first groove 1111s1 and the second groove 1112s2 are not limited to circular shapes, and may be elliptical shapes or any polygonal shapes. Fig.19a and Fig.19c In the first portion 1111g of the ground conductive pattern 1110g, any one of the first grooves 1111s and 1111s2 may be formed. In addition, in the second portion 1111g of the ground conductive pattern 1110g, any one of the second grooves 1112s and 1112s2 may be formed.

[0278] The antenna assembly of the present specification forms a conductive pattern that operates as a radiator according to a plurality of antenna operation modes, thereby enabling broadband operation. Figures 20a to 20c represents the electric field distribution formed on the conductive pattern of the antenna component under the conditions of the first frequency band to the third frequency band. Figures 20a to 20c In order to form Fig.11 The electric field distribution of the first radiation structure 1000 - 1 is used as a reference for description, but the description can also be applied to the second radiation structure 1000 - 2 in the same manner.

[0279] Reference Fig.11 , Fig.15a as well as Fig.20a In the first frequency band, the current distribution on the first conductive pattern 1110 and the third conductive pattern 1130 of the antenna assembly 1000 is higher than the current distribution in other regions. The first region Rp1a as the peak region of the current distribution can be formed in a region of the first conductive pattern 1110. The second region Rp2a as the peak region of the current distribution can be formed in a region of the third conductive pattern 1130. Thus, the first conductive pattern 1110 and the third conductive pattern 1130 can act as radiators in the first frequency band.

[0280] The first frequency band may be set to 617 to 960 MHz, but is not limited thereto. The first conductive pattern 1110 and the third conductive pattern 1130 may act as a dipole antenna in the first frequency band. The first conductive pattern 1110 and the third conductive pattern 1130 may act in a dipole antenna mode, such as Fig.12a (b) forms a radiation pattern along the vertical direction.

[0281] Fig.11 , Fig.15b as well as Fig.20b In the second frequency band, the current distribution on the first conductive pattern 1110 of the antenna assembly 1000 is higher than the current distribution in other regions. A peak region Rpb of the current distribution may be formed in the boundary region of the first conductive pattern 1110. Thus, the first conductive pattern 1110 may act as a radiator in the second frequency band.

[0282] The second frequency band may be set to 1520 to 4500 MHz, but is not limited thereto. Thus, the first conductive pattern 1110 may act as a monopole antenna in the second frequency band. By operating the first conductive pattern 1110 in the monopole antenna mode, Fig.12a (a) forms a radiation pattern in the side direction.

[0283] Reference Fig.11 , Fig.15c as well as Fig.20c , in the third frequency band, the current distribution on the second conductive pattern 1120 of the antenna assembly 1000 is higher than the current distribution in other areas. A peak area Rpc of the current distribution can be formed in the boundary area of ​​the second conductive pattern 1120. Thus, the second conductive pattern 1120 can act as a radiator in the third frequency band. The third frequency band can be set to 4500 to 6000 MHz, but is not limited thereto. Therefore, the second conductive pattern 1120 can act as a monopole antenna in the third frequency band. By operating the second conductive pattern 1120 in monopole antenna mode, Fig.14a (a) forms a radiation pattern in the side direction.

[0284] On the other hand, the antenna assembly of the present specification that operates in multiple operation modes can operate as a radiator in multiple frequency bands. Fig.21 The reflection coefficient characteristics that change depending on whether a slot for impedance matching is present in the CPW antenna structure of this specification.

[0285] Fig.21 (i) represents the reflection coefficient of the first structure in which no groove for impedance matching is formed in the feeding region of the CPW antenna structure. Fig.21(ii) of FIG. 16 shows the reflection coefficient of the second structure in which a slot for impedance matching is formed in the feeding area of ​​the CPW antenna structure. Fig.14a 16, the reflection coefficient of the first structure without the groove has a value of -12.4 to -15.3 dB in the third frequency band. The reflection coefficient of the second structure with the first groove 1111s and the second groove 1112s2 has a value of -19 to -30.3 dB in the third frequency band. Therefore, it can be seen that as the groove for impedance matching is formed in the feeding area of ​​the CPW antenna structure, the impedance matching characteristics under the third frequency band condition are improved.

[0286] Reference Fig.15a and Fig.21 In the first frequency band, the antenna assembly 1000 operates as a radiator in the first operation mode. In the first frequency band of 617 to 960 MHz, the reflection coefficient has a value of about -10 dB or less. Fig.15b and Fig.21 In the second frequency band, the antenna assembly 1000 operates as a radiator in the second operation mode. In the second frequency band of 1520 to 4500 MHz, the reflection coefficient has a value of about -10 dB or less. Fig.15c and Fig.21 In the third frequency band, the antenna assembly 1000 operates as a radiator in the third operation mode. In the third frequency band of 4500 to 6000 MHz, the reflection coefficient has a value of about -10 dB or less.

[0287] With the addition Fig.19a The first groove 1111s and the second groove 1112s can improve the value of the reflection coefficient in the frequency band of about 5 GHz. In this regard, it can be seen that with the addition of the first groove 1111s and the second groove 1112s, the reflection coefficient can be greatly improved at 5 GHz and 6 GHz. In addition, with the addition of the first groove 1111s and the second groove 1112s, the reflection coefficient can have a value of about -15 dB or less at a frequency between 5 GHz and 6 GHz.

[0288] The antenna assembly according to one aspect of the present specification has been described above. The antenna assembly including a plurality of dielectric substrates according to another aspect of the present specification will be described below.

[0289] Regarding this, Fig.22a The structure in which the first dielectric substrate and the second dielectric substrate of the antenna assembly of the embodiment are combined is shown. Figure 22b express Fig.22a The feeding structure of the antenna assembly is configured in the opaque area of ​​the glass panel.

[0290] Reference Fig.22a and Figure 22b , the antenna assembly 1000 may include a first dielectric substrate 1010a as a transparent substrate and a second dielectric substrate 1010b as an opaque substrate. The antenna assembly 1000 may include a first region 1100a corresponding to a radiator region and a second region 1100b corresponding to a feeding region. The antenna assembly 1000 may further include a protective layer 1031 and adhesive layers 1041 and 1042. The antenna module 1100 implemented by one or more transparent antenna elements may be configured in the first region 1100a. The feeding structure implemented by one or more second dielectric substrates 1010b may be configured in the second region 1100b.

[0291] The glass panel 310 to which the antenna assembly 1000 can be attached may include a transparent region 311 and an opaque region 312. The first dielectric substrate 1010a formed with a transparent antenna element may be attached to the transparent region 311 of the glass panel 310 using an adhesive layer 1041. A protective layer 1031 may be formed on an upper region of the first dielectric substrate 1010a.

[0292] The opaque area 312 of the glass panel 310 may be formed with Figure 6a The frit layer 312f of the glass panel 310 may be provided with a frit pattern. The frit pattern of the region where the second dielectric substrate 1010b is arranged in the frit layer 312f of the opaque region 312 may be removed. The second dielectric substrate 1010b may be arranged in the opaque region 312 from which the frit pattern is removed. An adhesive layer 1042 may be formed in the opaque region 312 from which the frit pattern is removed, and the second dielectric substrate 1010b may be attached to the opaque region 312 of the glass panel 310 by means of the adhesive layer 1042.

[0293] Reference Figure 1 , Figures 9a to 9c , Fig.11 , Fig.19a , Fig.22a as well as Figure 22b , a vehicle including an antenna assembly 1000 formed of a plurality of dielectric substrates is described.

[0294] The vehicle may include a glass panel 310 and an antenna assembly 1000 disposed on the glass panel 310. The glass panel 310 may include a transparent region 311 and an opaque region 312. The antenna assembly 1000 may include a first dielectric substrate 1010a, a first region 1100a, a second dielectric substrate 1010b, a second region 1100b, and a third region 1100c.

[0295] The first region 1100a may include an antenna element, which includes a conductive pattern on one side of the first dielectric substrate 1010a and radiates a wireless signal. The second region 1100b may include connection patterns 1110c and 1120c, which are connected to the antenna element and are disposed in the opaque region 312 of the glass panel 310. The first connection pattern 1110c may be connected to the Figure 7a The third region 1100c may include ground conductive patterns 1110g, 1120g and feed patterns 1110f, 1120f on one side of the second dielectric substrate 1010b. The first region 1100a may also be referred to as a radiator region, and the third region 1100c may be referred to as a ground region (or feed region).

[0296] The antenna element 1100 may be configured to include a plurality of antenna structures, and may also be referred to as an antenna module 1100. The antenna element 1100 may include a first radiation structure 1100-1 and a second radiation structure 1100-2.

[0297] The first radiation structure 1100-1 and the second radiation structure 1100-2 formed in the first area 1100a of the antenna assembly 1000 can be respectively implemented by more than two conductive patterns and operate in multiple frequency bands. The multiple conductive patterns formed in the first area 1100a may include a first conductive pattern 1110 and a third conductive pattern 1130. The multiple conductive patterns may also include a first conductive pattern 1110, a second conductive pattern 1120, and a third conductive pattern 1130.

[0298] The first radiation structure 1100-1 may include a first conductive pattern 1110, a second conductive pattern 1120, and a third conductive pattern 1130. The first conductive pattern 1110 may be composed of a plurality of sub-patterns, i.e., a plurality of conductive portions. The first conductive pattern 1110 may include a first portion 1111 and a second portion 1112. The first portion 1111 may be formed to be perpendicular to the second portion 1112. The second portion 1112 may be electrically connected to the feed pattern 1110f. In this regard, "electrical connection" may include direct connection of the conductive portions or coupling at a predetermined interval.

[0299] The second conductive pattern 1120 may be disposed on a side region or a lower region of the first conductive pattern 1110. The second conductive pattern 1120 may be electrically connected to the first portion 1111g of the ground conductive pattern 1110g. By further configuring the second conductive pattern 1120 in the antenna assembly 1000, resonance may be achieved in a frequency band different from the operating frequency bands of the first conductive pattern 1110 and the third conductive pattern 1130.

[0300] The third conductive pattern 1130 may be disposed on the other side of the first conductive pattern 1110. The third conductive pattern 1130 may be electrically connected to the second portion 1112g of the ground conductive pattern 1110g. The size of the second conductive pattern 1120 may be smaller than that of the third conductive pattern 1130. Thus, through the second conductive pattern 1120, the antenna assembly 1000 may act as a radiator in a higher frequency band.

[0301] The second conductive pattern 1120 may be disposed between the first portion 1111 of the first conductive pattern 1110 and the first ground conductive pattern 1110g. The second conductive pattern 1120 may be disposed between the first portion 1111 of the first conductive pattern 1110 and the second portion 1112 of the first conductive pattern 1110. Thus, the second conductive pattern 1120 is disposed in the lower region of the first conductive pattern 1110, which can reduce the size of the antenna assembly 1000 compared to the case where the second conductive pattern 1120 is disposed in a region on one side of the first conductive pattern 1110. The first portion 1111 of the first conductive pattern 1110 and the third conductive pattern 1130 may be disposed on opposite sides with respect to the second portion 1112 of the first conductive pattern 1110. The first portion 1111 of the first conductive pattern 1110 and the third conductive pattern 1130 may be disposed in a region on one side and a region on the other side with respect to the second portion 1112 of the first conductive pattern 1110.

[0302] The second radiation structure 1100-2 may include a fourth conductive pattern 1140, a fifth conductive pattern 1150, and a third conductive pattern 1160. The fourth conductive pattern 1140 may be composed of a plurality of sub-patterns, i.e., a plurality of conductive portions. The fourth conductive pattern 1140 may include a third portion 1141 and a fourth portion 1142. The third portion 1141 may be formed to be perpendicular to the fourth portion 1142, and the fourth portion 1142 may be electrically connected to the feed pattern 1110f. In this regard, "electrical connection" may include direct connection of the respective conductive portions or coupling at a predetermined interval.

[0303] The fifth conductive pattern 1150 may be disposed on a side region or a lower region of the fourth conductive pattern 1140. The fifth conductive pattern 1150 may be electrically connected to the first portion 1121g of the second ground conductive pattern 1120g. By further configuring the fifth conductive pattern 1150 in the antenna assembly 1000, resonance may be performed in a frequency band different from the operating frequency bands of the fourth conductive pattern 1140 and the sixth conductive pattern 1160.

[0304] The sixth conductive pattern 1160 may be disposed on the other side of the fourth conductive pattern 1140. The sixth conductive pattern 1160 may be electrically connected to the second portion 1122g of the second ground conductive pattern 1120g. The size of the fifth conductive pattern 1150 may be smaller than that of the sixth conductive pattern 1160. Thus, through the fifth conductive pattern 1150, the antenna assembly 1000 may operate as a radiator at a higher frequency band.

[0305] The fifth conductive pattern 1150 may be disposed between the third portion 1141 of the fourth conductive pattern 1140 and the second ground conductive pattern 1120g. The fifth conductive pattern 1150 may be disposed between the third portion 1141 of the fourth conductive pattern 1140 and the fourth portion 1142 of the fourth conductive pattern 1140. Thus, the fifth conductive pattern 1150 is disposed in the lower region of the fourth conductive pattern 1140, which can reduce the size of the antenna assembly 1000 compared to the case where the fifth conductive pattern 1150 is disposed in the region on one side of the fourth conductive pattern 1140. The third portion 1141 of the fourth conductive pattern 1140 and the sixth conductive pattern 1160 may be disposed on the opposite side with respect to the fourth portion 1142 of the fourth conductive pattern 1140. The third portion 1141 of the fourth conductive pattern 1140 and the sixth conductive pattern 1160 may be disposed in the region on one side and the region on the other side with respect to the fourth portion 1142 of the fourth conductive pattern 1140.

[0306] The first radiation structure 1100-1 and the second radiation structure 1100-2 may be formed in a symmetrical structure with one axis as the center. In this regard, the third conductive pattern 1130 of the first radiation structure 1100-1 may be configured to face the sixth conductive pattern 1160 of the second radiation structure 1100-2. The first radiation structure 1100-1 and the second radiation structure 1100-2 may be configured to perform multiple input multiple output (MIMO).

[0307] On the other hand, the antenna assembly of the present specification can be formed by a transparent antenna structure.

The first conductive pattern 1110 and the third conductive pattern 1130 may be formed in a metal grid pattern 1020a. The metal grid pattern 1020a may be formed to have an open area OA with a dummy metal grid pattern 1020b. The first conductive pattern 1110 and the third conductive pattern 1130 may be formed in a CPW structure on a dielectric substrate 1010a.

The first conductive pattern 1110, the second conductive pattern 1120, and the third conductive pattern 1130 can be implemented in a CPW structure on the dielectric substrate 1010. The first conductive pattern 1110, the second conductive pattern 1120, and the third conductive pattern 1130 can be formed by a metal grid pattern 1020a. The metal grid pattern 1020a can be formed to have an open area OA with a dummy metal grid pattern 1020b. The first conductive pattern 1110, the second conductive pattern 1120, and the third conductive pattern 1130 can be formed in a CPW structure on the dielectric substrate 1010a.

[0309] The antenna assembly 1000 may include a plurality of dummy grid patterns 1020b in the radiator region on the dielectric substrate 1010a, that is, the outside portion of the first region 1100a. On the other hand, the plurality of dummy grid patterns 1020b may also be configured in the dielectric region between the first conductive pattern 1110 to the third conductive pattern 1130. The plurality of dummy grid patterns 1020b may be formed to be not connected to the feed pattern 1110f and the ground region 1110g. The plurality of dummy grid patterns 1020b may be formed to be separated from each other.

[0310] Next, an antenna assembly including a plurality of dielectric substrates according to another aspect of the present specification will be described. Fig.23a A stacked structure of an antenna assembly according to still another aspect of the present specification. Figure 23b Representation composition Fig.20a A front view of the various layers of the structure with through-holes connecting the conductive patterns of the feed structure. Fig.23c Indicated in Fig.23a The upper conductive pattern of the feeding structure is connected with a connecting element structure.

[0311] Regarding this, refer to Figure 1 , Figures 8a to 9c , Fig.11 , Fig.19a , Figures 23a to 23c , a vehicle including an antenna assembly 1000 formed of a plurality of dielectric substrates is described.

[0312] The vehicle may include a glass panel 310 and an antenna assembly 1000 disposed on the glass panel 310. The antenna assembly 1000 may include a first dielectric substrate 1010a, a first region 1100a, a second dielectric substrate 1010b, a second region 1100b, and a connection region 1100c.

[0313] The first region 1100a may include an antenna element, which is configured to include a conductive pattern on one side of the first dielectric substrate 1010a and radiate a wireless signal. The second region 1100b may include a first ground conductive pattern 1110g, a second ground conductive pattern 1120g, a first feed pattern 1110f, and a second feed pattern 1120f on one side of the second dielectric substrate 1010b. The first region 1100a may also be referred to as a radiator region, and the second region 1100b may be referred to as a ground region (or feed region). The connection region 1100c may include a third ground conductive pattern 1130g, a fourth ground conductive pattern 1140g, a third feed pattern 1130f, and a fourth feed pattern 1140f on the other side of the second dielectric substrate 1010b.

[0314] The antenna element 1100 may be configured to include a plurality of antenna structures, and may also be referred to as an antenna module 1100. The antenna element 1100 may include a first radiation structure 1100-1 and a second radiation structure 1100-2.

[0315] The first radiation structure 1100-1 and the second radiation structure 1100-2 formed in the first area 1100a of the antenna assembly 1000 can be respectively implemented by more than two conductive patterns and operate in multiple frequency bands. The multiple conductive patterns formed in the first area 1100a may include a first conductive pattern 1110 and a third conductive pattern 1130. The multiple conductive patterns may also include a first conductive pattern 1110, a second conductive pattern 1120, and a third conductive pattern 1130.

[0316] The first radiation structure 1100-1 may include a first conductive pattern 1110, a second conductive pattern 1120, and a third conductive pattern 1130. The first conductive pattern 1110 may be composed of a plurality of sub-patterns, i.e., a plurality of conductive portions. The first conductive pattern 1110 may include a first portion 1111 and a second portion 1112. The first portion 1111 may be formed to be perpendicular to the second portion 1112. The second portion 1112 may be electrically connected to the feed pattern 1110f. In this regard, "electrical connection" may include direct connection of the conductive portions or coupling at a predetermined interval.

[0317] The second conductive pattern 1120 may be disposed on a side region or a lower region of the first conductive pattern 1110. The second conductive pattern 1120 may be electrically connected to the first portion 1111g of the ground conductive pattern 1110g. By further configuring the second conductive pattern 1120 in the antenna assembly 1000, resonance may be achieved in a frequency band different from the operating frequency bands of the first conductive pattern 1110 and the third conductive pattern 1130.

[0318] The third conductive pattern 1130 may be disposed on the other side of the first conductive pattern 1110. The third conductive pattern 1130 may be electrically connected to the second portion 1112g of the ground conductive pattern 1110g. The size of the second conductive pattern 1120 may be smaller than that of the third conductive pattern 1130. Thus, through the second conductive pattern 1120, the antenna assembly 1000 may act as a radiator in a higher frequency band.

[0319] The second conductive pattern 1120 may be disposed between the first portion 1111 of the first conductive pattern 1110 and the first ground conductive pattern 1110g. The second conductive pattern 1120 may be disposed between the first portion 1111 of the first conductive pattern 1110 and the second portion 1112 of the first conductive pattern 1110. Thus, the second conductive pattern 1120 is disposed in the lower region of the first conductive pattern 1110, which can reduce the size of the antenna assembly 1000 compared to the case where the second conductive pattern 1120 is disposed in a region on one side of the first conductive pattern 1110. The first portion 1111 of the first conductive pattern 1110 and the third conductive pattern 1130 may be disposed on opposite sides with respect to the second portion 1112 of the first conductive pattern 1110. The first portion 1111 of the first conductive pattern 1110 and the third conductive pattern 1130 may be disposed in a region on one side and a region on the other side with respect to the second portion 1112 of the first conductive pattern 1110.

[0320] The second radiation structure 1100-2 may include a fourth conductive pattern 1140, a fifth conductive pattern 1150, and a third conductive pattern 1160. The fourth conductive pattern 1140 may be composed of a plurality of sub-patterns, i.e., a plurality of conductive portions. The fourth conductive pattern 1140 may include a third portion 1141 and a fourth portion 1142. The third portion 1141 may be formed to be perpendicular to the fourth portion 1142, and the fourth portion 1142 may be electrically connected to the feed pattern 1110f. In this regard, "electrical connection" may include direct connection of the respective conductive portions or coupling at a predetermined interval.

[0321] The fifth conductive pattern 1150 may be disposed on a side region or a lower region of the fourth conductive pattern 1140. The fifth conductive pattern 1150 may be electrically connected to the first portion 1121g of the second ground conductive pattern 1120g. By further configuring the fifth conductive pattern 1150 in the antenna assembly 1000, resonance may be performed in a frequency band different from the operating frequency bands of the fourth conductive pattern 1140 and the sixth conductive pattern 1160.

[0322] The sixth conductive pattern 1160 may be disposed on the other side of the fourth conductive pattern 1140. The sixth conductive pattern 1160 may be electrically connected to the second portion 1122g of the second ground conductive pattern 1120g. The size of the fifth conductive pattern 1150 may be smaller than that of the sixth conductive pattern 1160. Thus, through the fifth conductive pattern 1150, the antenna assembly 1000 may operate as a radiator at a higher frequency band.

[0323] The fifth conductive pattern 1150 may be disposed between the third portion 1141 of the fourth conductive pattern 1140 and the second ground conductive pattern 1120g. The fifth conductive pattern 1150 may be disposed between the third portion 1141 of the fourth conductive pattern 1140 and the fourth portion 1142 of the fourth conductive pattern 1140. Thus, the fifth conductive pattern 1150 is disposed in the lower region of the fourth conductive pattern 1140, which can reduce the size of the antenna assembly 1000 compared to the case where the fifth conductive pattern 1150 is disposed in the region on one side of the fourth conductive pattern 1140. The third portion 1141 of the fourth conductive pattern 1140 and the sixth conductive pattern 1160 may be disposed on the opposite side with respect to the fourth portion 1142 of the fourth conductive pattern 1140. The third portion 1141 of the fourth conductive pattern 1140 and the sixth conductive pattern 1160 may be disposed in the region on one side and the region on the other side with respect to the fourth portion 1142 of the fourth conductive pattern 1140.

[0324] The first radiation structure 1100-1 and the second radiation structure 1100-2 may be formed in a symmetrical structure with one axis as the center. In this regard, the third conductive pattern 1130 of the first radiation structure 1100-1 may be configured to face the sixth conductive pattern 1160 of the second radiation structure 1100-2. The first radiation structure 1100-1 and the second radiation structure 1100-2 may be configured to perform multiple input multiple output (MIMO).

[0325] On the other hand, the ground conductive patterns of the antenna assembly 1000 of the present specification can be connected to each other through the vertically structured through-holes, so that the ground conductive patterns of different layers can be electrically connected. In addition, the feeding patterns can also be connected to each other through the vertically structured through-holes, thereby transmitting signals through the feeding patterns of different layers.

[0326] Reference Fig.23a, the antenna module 1100 may be combined with the feeding structure 1100f. In this regard, the antenna module 1100 may include a first dielectric substrate 1010a as a transparent substrate and a conductive region 1110. The antenna module 1100 may include a protective layer 1031 configured on the upper portion of the first conductive pattern 1100. The antenna module 1100 may include an adhesive layer 1041 that attaches the first dielectric substrate 1010a to the transparent region 311 of the glass panel 310. In the feeding structure 1100f, conductive regions 1100b and 1100c may be respectively configured at the lower and upper portions of the second dielectric substrate 1010b as an opaque substrate. The conductive region 1100b at the lower portion may be configured on the opaque region 312 of the glass panel 310 with the aid of an adhesive layer 1042.

Figure 23b (b) shows the second conductive region 1100c of the first feeding structure 1100f-1 and the second feeding structure 1100f-2 formed on the other side of the second dielectric substrate 1010b. Fig.19a The first conductive region 1100b may be formed with a first slit 1111s and a second slit 1112s. Fig.23c The second conductive region 1100c may be formed in a structure without a slit. However, the structure is not limited to this. The second conductive region 1100c may be formed in a structure without a slit. Fig.19a Formed with a slit structure.

The first pin 313P1 may be connected to the first portion 1131g of the third ground conductive pattern 1130g. The second pin 313P2 may be connected to the third feed pattern 1130f. The third pin 313P3 may be connected to the second portion 1132g of the third ground conductive pattern 1130g.

[0334] The connection element 313 may be implemented by a coaxial cable, but is not limited thereto. The connection element 313 may also be implemented by a cable assembly in a planar form. The first pin 313P1 and the third pin 313P3 of the first connection portion 313c1 may be implemented by an outer conductor of a coaxial cable. The first pin 313P1 and the third pin 313P3 of the first connection portion 313c1 may be implemented by an outer conductor of a single body. The second pin 313P2 of the first connection portion 313c1 may be implemented by an inner conductor of a coaxial cable. The second connection portion 313c2 may be connected to the TCU 300.

[0335] Hereinafter, an antenna assembly including a plurality of dielectric substrates according to another aspect of the present specification will be described. Figure 1 , Figures 9a to 9c , Fig.11 , Fig.13a , Figures 23a to 23c , a vehicle including an antenna assembly 1000 formed of a plurality of dielectric substrates is described.

[0336] The vehicle may include a glass panel 310 and an antenna assembly 1000 disposed on the glass panel 310. The glass panel 310 may include a transparent region 311 and an opaque region 312. The antenna assembly 1000 may include a first dielectric substrate 1010a, a radiator region 1100a, a second dielectric substrate 1010b, a first conductive region 1100b, and a second conductive region 1100c.

[0337] The radiator region 1100a may include an antenna element that includes a conductive pattern on one side of the first dielectric substrate 1010a and radiates a wireless signal. The first conductive region 1100b may include a first ground conductive pattern 1110g, a second ground conductive pattern 1120g, a first feed pattern 1110f, and a second feed pattern 1120f on one side of the second dielectric substrate 1010b. The second conductive region 1100c may include a third ground conductive pattern 1130g, a fourth ground conductive pattern 1140g, a third feed pattern 1130f, and a fourth feed pattern 1140f on the other side of the second dielectric substrate 1010b.

[0338] The antenna element 1100 may be configured to include a plurality of antenna structures, and may also be referred to as an antenna module 1100. The antenna element 1100 may include a first radiation structure 1100-1 and a second radiation structure 1100-2.

[0339] The first radiation structure 1100-1 and the second radiation structure 1100-2 formed in the first area 1100a of the antenna assembly 1000 can be respectively implemented by more than two conductive patterns and operate in multiple frequency bands. The multiple conductive patterns formed in the first area 1100a may include a first conductive pattern 1110 and a third conductive pattern 1130. The multiple conductive patterns may also include a first conductive pattern 1110, a second conductive pattern 1120, and a third conductive pattern 1130.

[0340] The first radiation structure 1100-1 may include a first conductive pattern 1110, a second conductive pattern 1120, and a third conductive pattern 1130. The first conductive pattern 1110 may be composed of a plurality of sub-patterns, i.e., a plurality of conductive portions. The first conductive pattern 1110 may include a first portion 1111 and a second portion 1112. The first portion 1111 may be formed to be perpendicular to the second portion 1112. The second portion 1112 may be electrically connected to the feed pattern 1110f. In this regard, "electrical connection" may include direct connection of the conductive portions or coupling at a predetermined interval.

[0341] The second conductive pattern 1120 may be disposed on a side region or a lower region of the first conductive pattern 1110. The second conductive pattern 1120 may be electrically connected to the first portion 1111g of the ground conductive pattern 1110g. By further configuring the second conductive pattern 1120 in the antenna assembly 1000, resonance may be achieved in a frequency band different from the operating frequency bands of the first conductive pattern 1110 and the third conductive pattern 1130.

[0342] The third conductive pattern 1130 may be disposed on the other side of the first conductive pattern 1110. The third conductive pattern 1130 may be electrically connected to the second portion 1112g of the ground conductive pattern 1110g. The size of the second conductive pattern 1120 may be smaller than that of the third conductive pattern 1130. Thus, through the second conductive pattern 1120, the antenna assembly 1000 may act as a radiator in a higher frequency band.

[0343] The second conductive pattern 1120 may be disposed between the first portion 1111 of the first conductive pattern 1110 and the first ground conductive pattern 1110g. The second conductive pattern 1120 may be disposed between the first portion 1111 of the first conductive pattern 1110 and the second portion 1112 of the first conductive pattern 1110. Thus, the second conductive pattern 1120 is disposed in the lower region of the first conductive pattern 1110, which can reduce the size of the antenna assembly 1000 compared to the case where the second conductive pattern 1120 is disposed in a region on one side of the first conductive pattern 1110. The first portion 1111 of the first conductive pattern 1110 and the third conductive pattern 1130 may be disposed on opposite sides with respect to the second portion 1112 of the first conductive pattern 1110. The first portion 1111 of the first conductive pattern 1110 and the third conductive pattern 1130 may be disposed in a region on one side and a region on the other side with respect to the second portion 1112 of the first conductive pattern 1110.

[0344] The second radiation structure 1100-2 may include a fourth conductive pattern 1140, a fifth conductive pattern 1150, and a third conductive pattern 1160. The fourth conductive pattern 1140 may be composed of a plurality of sub-patterns, i.e., a plurality of conductive portions. The fourth conductive pattern 1140 may include a third portion 1141 and a fourth portion 1142. The third portion 1141 may be formed to be perpendicular to the fourth portion 1142, and the fourth portion 1142 may be electrically connected to the feed pattern 1110f. In this regard, "electrical connection" may include direct connection of the respective conductive portions or coupling at a predetermined interval.

[0345] The fifth conductive pattern 1150 may be disposed on a side region or a lower region of the fourth conductive pattern 1140. The fifth conductive pattern 1150 may be electrically connected to the first portion 1121g of the second ground conductive pattern 1120g. By further configuring the fifth conductive pattern 1150 in the antenna assembly 1000, resonance may be performed in a frequency band different from the operating frequency bands of the fourth conductive pattern 1140 and the sixth conductive pattern 1160.

[0346] The sixth conductive pattern 1160 may be disposed on the other side of the fourth conductive pattern 1140. The sixth conductive pattern 1160 may be electrically connected to the second portion 1122g of the second ground conductive pattern 1120g. The size of the fifth conductive pattern 1150 may be smaller than that of the sixth conductive pattern 1160. Thus, through the fifth conductive pattern 1150, the antenna assembly 1000 may operate as a radiator at a higher frequency band.

[0347] The fifth conductive pattern 1150 may be disposed between the third portion 1141 of the fourth conductive pattern 1140 and the second ground conductive pattern 1120g. The fifth conductive pattern 1150 may be disposed between the third portion 1141 of the fourth conductive pattern 1140 and the fourth portion 1142 of the fourth conductive pattern 1140. Thus, the fifth conductive pattern 1150 is disposed in the lower region of the fourth conductive pattern 1140, which can reduce the size of the antenna assembly 1000 compared to the case where the fifth conductive pattern 1150 is disposed in the region on one side of the fourth conductive pattern 1140.

The third portion 1141 of the fourth conductive pattern 1140 and the sixth conductive pattern 1160 may be disposed in the region on one side and the region on the other side with respect to the fourth portion 1142 of the fourth conductive pattern 1140.

[0348] The first radiation structure 1100-1 and the second radiation structure 1100-2 may be formed in a symmetrical structure with one axis as the center. In this regard, the third conductive pattern 1130 of the first radiation structure 1100-1 may be configured to face the sixth conductive pattern 1160 of the second radiation structure 1100-2. The first radiation structure 1100-1 and the second radiation structure 1100-2 may be configured to perform multiple input multiple output (MIMO).

[0349] On the other hand, the ground conductive patterns of the antenna assembly 1000 of the present specification can be connected to each other through the vertically structured through-holes, so that the ground conductive patterns of different layers can be electrically connected. In addition, the feeding patterns can also be connected to each other through the vertically structured through-holes, thereby transmitting signals through the feeding patterns of different layers.

[0350] In this regard, the first ground conductive pattern 1110g may be electrically connected to the third ground conductive pattern 1130g using at least one first through hole 1110v. The second ground conductive pattern 1120g may be electrically connected to the fourth ground conductive pattern 1140g using at least one second through hole 1120v. The first feed pattern 1110f may be electrically connected to the third feed pattern 1130f using at least one third through hole 1130v. The second feed pattern 1120f may be electrically connected to the fourth feed pattern 1140f using at least one fourth through hole 1140v.

[0351] On the other hand, the antenna assembly of the present specification may include a first transparent dielectric substrate and a second dielectric substrate formed with a transparent electrode layer. In this regard, Fig.24a and Figure 24b The figure shows the manufacturing process of combining the antenna assembly of the embodiment with the glass panel.

[0352] Reference Fig.24a (a), a first transparent dielectric substrate 1000a having a transparent electrode layer can be manufactured. In addition, a second dielectric substrate 1000b having a feeding pattern 1120f and grounding patterns 1121g and 1122g formed on both sides of the feeding pattern 1120f can be manufactured. The second dielectric substrate 1000b can be implemented by an FPCB, but is not limited thereto. Adhesion areas corresponding to the adhesive layer 1041 can be formed on the first transparent dielectric substrate 1000a and the second dielectric substrate 1000b, respectively.

[0353] Reference Fig.24a (b), a glass panel 310 having a transparent area 311 and an opaque area 312 can be manufactured. In addition, the antenna assembly 1000 can be manufactured by combining at least one second dielectric substrate 1000b in the lower area of ​​the first transparent dielectric substrate 1000a. The first transparent dielectric substrate 1000a and the second dielectric substrate 1000b can be combined by ACF bonding or low-temperature welding to realize a transparent antenna assembly. Thus, the first conductive pattern formed on the first transparent dielectric substrate 1000a can be electrically connected to the second conductive pattern formed on the second dielectric substrate 1000b. When a plurality of antenna elements are implemented on the glass panel 310, the feeding structure 1100f made of the second dielectric substrate 1000b can also be implemented as a plurality of feeding structures.

[0354] Reference Fig.24a(c), the transparent antenna assembly 1000 may be attached to the glass panel 310. In this regard, the first transparent dielectric substrate 1000a formed with a transparent electrode layer may be disposed in the transparent region 311 of the glass panel 310. On the other hand, the second dielectric substrate 1000b as an opaque substrate may be disposed in the opaque region 312 of the glass panel 310.

[0355] Reference Fig.24a (d), the first transparent dielectric substrate 1000a and the second dielectric substrate 1000b can be joined at a first position P1. The connector component 313 such as a FAKRA cable can be joined to the second dielectric substrate 1000b at a second position P2. The transparent antenna assembly 1000 can be combined with the telematics control unit (TCU) 300 using the connector component 313. To this end, the second conductive pattern formed on the second dielectric substrate 1000b can be electrically connected to the connector at one end of the connector component 313. The connector at the other end of the connector component 313 can be electrically connected to the telematics control unit (TCU) 300.

[0356] Figure 24b The antenna components and Fig.24a The difference in the structure of the antenna assembly is that the opaque substrate is integrally made on the glass panel 310, rather than being made separately. Figure 24b In the antenna assembly, the feeding structure implemented by the opaque substrate is implemented by directly printing on the glass panel 310, rather than being made separately by the FPCB.

[0357] Reference Figure 24b (a), a first transparent dielectric substrate 1000a having a transparent electrode layer formed thereon can be manufactured. In addition, a glass panel 310 having a transparent region 311 and an opaque region 312 can be manufactured. In the glass panel manufacturing process of the vehicle, a metal wire / pad for connector connection can be realized (fired). As in the case of a heat wire realized in the glass of the vehicle, a transparent antenna mounting portion can be realized in a metal form on the glass panel 310. In this regard, in order to electrically connect to the first conductive pattern of the first transparent dielectric substrate 1000a, a second conductive pattern can be realized in the region having the adhesive layer 1041 formed thereon.

[0358] In this regard, the second dielectric substrate 1000b formed with the second conductive pattern may be manufactured integrally with the glass panel 310. The second dielectric substrate 1000b may be integrally formed with the glass panel 310 at the opaque region 312 of the glass panel 310. The frit pattern 312 formed with the opaque region 312 of the second dielectric substrate 1000b may be removed. The second conductive pattern may be realized by forming a feed pattern 1120f on the second dielectric substrate 1000b and forming ground patterns 1121g, 1122g on both sides of the feed pattern 1120f.

Fig.25 This shows a configuration in which a plurality of antenna modules disposed at different positions of the vehicle of this specification are combined with other components of the vehicle.

[0362] Reference Figures 1 to 25The vehicle 500 has a conductive vehicle body that acts as an electrical ground.

The communication module 300 may include a transceiver circuit 1250 and a processor 1400. The communication module 300 may be equivalent to a TCU of the vehicle or constitute at least a portion of a TCU.

[0363] The vehicle 500 may include an object detection device 520 and a navigation system 550. The vehicle 500 may include an additional processor 570 in addition to the processor 1400 included in the communication module 300. The additional processor 570 may be physically distinguished from the processor 1400 or may be functionally distinguished and implemented on a substrate. The processor 1400 may be implemented as a TCU, and the processor 570 may be implemented as an ECU (Electronic Control Unit).

[0364] In the case where the vehicle 500 is an autonomous driving vehicle, the processor 570 may be an autonomous driving integrated controller (ADCU: Automated Driving Control Unit) integrated with an ECU. Based on the information sensed by the camera 531, the radar 532, and / or the laser radar 533, the processor 570 may search for a path and control the acceleration and deceleration of the vehicle 500. To this end, the processor 570 may be linked with the processor 530 equivalent to the MCU in the object detection device 520 and / or the communication module 300 equivalent to the TCU.

[0365] The vehicle 500 may include a first transparent dielectric substrate 1010a and a second dielectric substrate 1010b disposed on a glass panel 310. The first transparent dielectric substrate 1010a may be formed inside the glass panel 310 of the vehicle or attached to the surface of the glass panel 310. The first transparent dielectric substrate 1010a may be configured to form a conductive pattern in the form of a metal mesh. The vehicle 500 may include an antenna module 1100 in which a conductive pattern in the form of a metal mesh is formed on one side of the dielectric substrate 1010 to radiate a wireless signal.

[0366] The antenna assembly 1000 may include a first antenna module 1100a to a fourth antenna module 1100d to perform multiple input multiple output (MIMO). The first antenna module 1100a may be configured at the upper left side of the glass panel 310, the second antenna module 1100b may be configured at the lower left side, the third antenna module 1100c may be configured at the upper right side, and the fourth antenna module 1100d may be configured at the lower right side. The first antenna module 1100a may be referred to as the first antenna ANT1, the second antenna module 1100b may be referred to as the second antenna ANT2, the third antenna module 1100c may be referred to as the third antenna ANT3, and the fourth antenna module 1100d may be referred to as the fourth antenna ANT4.

[0367] As described above, the vehicle 500 may include a telematics control unit (TCU) 300 as a communication module. The TCU 300 may be controlled to transmit and receive signals through at least one of the first to fourth antenna modules 1100a to 1100d. The TCU 300 may include a transceiver circuit 1250 and a baseband processor 1400.

[0368] Thus, the vehicle may further include a transceiver circuit 1250 and a processor 1400. A portion of the transceiver circuit 1250 may also be configured in units of antenna modules or a combination thereof. The transceiver circuit 1250 may be controlled so that a wireless signal of at least one of the first to third frequency bands is radiated through antenna modules ANT1 to ANT4. The first to third frequency bands may be a low frequency band (LB), a middle frequency band (MB), and a high frequency band (HB) for 4G / 5G wireless communications, but are not limited thereto.

[0369] The processor 1400 is operably combined with the transceiver circuit 1250 and can be composed of a modem operating at a baseband. The processor 1400 can be configured to receive or send a signal through at least one of the first antenna module ANT1 and the second antenna module ANT2. The processor 1400 can perform a diversity operation or a MIMO operation using the first antenna module ANT1 and the second antenna module ANT2 to transmit the signal to the interior of the vehicle.

[0370] The antenna module may be disposed in different areas on one side and the other side of the glass panel 310. The antenna module may simultaneously receive signals from the front direction of the vehicle and perform multiple input multiple output (MIMO). In this regard, the antenna module may further include a third antenna module ANT3 and a fourth antenna module ANT4 in addition to the first antenna module ANT1 and the second antenna module ANT2 to perform 4X4 MIMO.

[0371] The processor 1400 may be configured to select an antenna module to communicate with the entity based on the driving path of the vehicle and the communication path of the entity communicating with the vehicle. The processor 1400 may perform MIMO operation using the first antenna module ANT1 and the second antenna module ANT2 based on the direction of the vehicle. Alternatively, the processor 1400 may perform MIMO operation using the third antenna module ANT2 and the second antenna module ANT4 based on the direction of the vehicle.

[0372] The processor 1400 may perform multiple-input multiple-output (MIMO) in the first frequency band through two or more antennas among the first antenna ANT1 to the fourth antenna ANT4. The processor 1400 may perform multiple-input multiple-output (MIMO) in at least one of the second frequency band and the third frequency band through two or more antennas among the first antenna ANT1 to the fourth antenna ANT4.

[0373] Therefore, when the signal transmission and reception performance of the vehicle decreases in a certain frequency band, the vehicle can transmit and receive signals through other frequency bands. As an example, for a wider communication coverage and connection reliability, the vehicle can preferentially perform communication connection in the first frequency band, which is a low frequency band, and then perform communication connection in the second and third frequency bands.

[0374] The processor 1400 can control the transceiver circuit 1250 to perform carrier aggregation (CA) or dual connectivity (DC) through at least one of the first antenna ANT1 to the fourth antenna ANT4. In this regard, the communication capacity can be expanded by aggregating the second and third frequency bands that are wider than the first frequency band. In addition, the communication reliability can be improved by utilizing a plurality of antenna elements configured in different areas of the vehicle to provide dual connectivity with surrounding vehicles or entities.

[0384] According to the present specification, the boundary of the antenna region and the boundary of the dummy pattern region are separated by a prescribed interval, thereby making it possible to ensure the invisibility of the transparent antenna and the antenna assembly including the same without deteriorating the antenna performance.

[0385] According to the present specification, an open dummy structure is formed as a cross point of a metal line of a dummy region or a portion of a metal line is disconnected, thereby ensuring the invisibility of a transparent antenna and an antenna assembly including the same without deteriorating or reducing antenna performance.

[0386] According to the present specification, visibility can be improved without antenna performance degradation in a transparent antenna through optimal design of a slit having a dummy pattern of an open area and an open area with a radiator area.

[0387] According to the present specification, a broadband antenna structure made of a transparent material can be provided through a vehicle glass or a display area of ​​an electronic device, can operate in a broadband, and can reduce feed loss and improve antenna efficiency.

[0388] According to the present specification, it is possible to provide a transparent antenna structure that can wirelessly communicate in 4G and 5G frequency bands while minimizing antenna performance variations and transparency differences between an antenna area and a surrounding area.
