Description

Glass assembly having an antenna assembly and a vehicle having the same

[0001] The present disclosure relates to a glass assembly having an antenna assembly disposed thereon. Particular embodiments relate to a glass assembly having a transparent antenna assembly disposed thereon and a vehicle having the same.

[0002] Vehicles can perform wireless communication services with other vehicles, surrounding objects, infrastructure, or base stations. In this regard, various communication services can be provided through wireless communication systems utilizing LTE or 5G communication technologies. Meanwhile, some LTE frequency bands may be allocated to provide 5G communication services.

[0003] Meanwhile, the vehicle body and roof are made of metal, which poses a problem of radio wave blocking. Therefore, a separate antenna structure can be placed on the upper portion of the vehicle body or roof. Alternatively, if the antenna structure is placed on the lower portion of the vehicle body or roof, the portion of the vehicle body or roof corresponding to the antenna placement area can be formed of a non-metallic material.

[0004] However, from a design perspective, the vehicle body or roof needs to be formed as one piece. In such cases, the exterior of the vehicle body or roof may be formed of metal. Consequently, there is a risk that the vehicle body or roof may significantly reduce antenna efficiency.

[0005] In this regard, transparent antennas can be placed on the glass corresponding to the vehicle's window to increase communication capacity without changing the vehicle's exterior design. However, there is a problem in that the antenna radiation efficiency and impedance bandwidth characteristics deteriorate due to the electrical loss of the transparent material antenna.

[0006] Meanwhile, a transparent antenna assembly disposed on a vehicle's glass panel may be formed with multiple radiating structures to support multi-input multi-output (MIMO) operation to expand communication capacity. The multiple radiating structures of the transparent antenna assembly need to support MIMO operation even in low bands (LB) while being disposed on the vehicle's glass panel at various locations. Accordingly, the multiple radiating structures of the transparent antenna assembly need to be disposed adjacent to each other.

[0007] In this regard, PCT / KR2022 / 010240 and PCT / KR2022 / 010223 propose a transparent antenna assembly having multiple radiating structures. However, as the multiple radiating structures of the transparent antenna assembly are arranged adjacently, the isolation between the multiple radiating structures may increase. In particular, there is a problem in that the isolation is further reduced when the transparent antenna assembly arranged on a glass panel is combined with a metal vehicle frame.

[0008] Additionally, transparent antenna assemblies must maintain a certain level of antenna performance across various 4G / 5G wireless communication frequency bands. In particular, transparent antenna assemblies may experience reduced antenna efficiency to maintain transparency. Therefore, transparent antenna assemblies may experience reduced antenna efficiency in high band (HB) or ultra-high band (UHB).

[0009] An object of the present specification is to provide an antenna assembly made of a transparent material with improved isolation between antennas on a vehicle glass panel.

[0010] An object of the present specification is to improve the isolation between multiple radiating structures of a transparent antenna assembly by placing the multiple radiating structures adjacent to each other.

[0083] An antenna assembly (1000) in the form of a transparent electrode may be placed between a first glass (10a) and a second glass (10b). The first glass (10a) and the second glass (10b) may be formed of laminated glass, but are not limited thereto and may be changed depending on the application. The first glass (10a) and the second glass (10b) may form a double-laminated glass structure bonded by a film layer (1030). The film layer (1030) may be formed of a PVB (Polyvinyl butyral) layer, but are not limited thereto and may be changed depending on the application.

[0084] A flexible circuit board (1200) having power supply patterns formed on the inside of a glass panel (10) of a double-laminated glass structure may be arranged to surround the outer area of ​​the glass panel (10). In addition, the flexible circuit board (1200) may be connected to a connector (100c) or RF cable (110c) that may be connected to a TCU on the first glass (10a), which is the inner glass.

[0085] The RF cable (110c) may be configured to include a signal line (111c) on the inner side, a ground (112c) on the outer side, and a dielectric region (110d) between the signal line (111c) and the ground (112c). The RF cable (110c) may be implemented as a coaxial cable or a pakra cable and may be connected to a connection pad (100cp). The signal line (111c) on the inner side of the RF cable (110c) may be connected to a feed line of a connection pad (100cp) of a flexible circuit board (1200) through a soldering structure (112s). The dielectric region (110d) and the ground (112c) may be partially removed at the corresponding portion so that the signal line (111c) and the feed line of the connection pad (100cp) are connected through the soldering structure (112s).

[0086] The frame (9) may include a metal material, and a sealant (7) may be filled between the groove (9g) and the glass (10). The groove (9g) may be formed to have a step with respect to the inner boundary of the frame (9). Glass (10) having an opaque area (12) formed therein may be placed in the groove (9g) formed to have a step with respect to the inner end of the frame (9). As the glass (10) is placed in the groove (9g), the step of the groove (9g) may be regarded as non-existent from the outside of the vehicle.

[0087] A glass panel (10) may be coupled or attached to a frame (9) of a vehicle. The frame (9) of the vehicle may be formed of a metal material. The glass panel (10) may be configured to include a first glass (10a), a second glass (10b), and a film layer (1030). The glass panel (10) may include a transparent region (11) and an opaque region (12). The opaque region (12) may be a black mask region or a frit region.

[0088] An opaque area (12) may be formed on the first glass (10a). The vehicle frame (9) may be extended to correspond to the opaque area (12). In this regard, radio interference may occur between the vehicle frame (9) made of a metal material and the flexible printed circuit board (1200) on which the feeding pattern is formed. A signal applied to the transparent antenna module by the feeding pattern of the flexible printed circuit board (1200) may be subject to radio interference by the vehicle frame (9) made of a metal material. In particular, interference may occur in a low-band (LB) signal by the vehicle frame (9), resulting in a degradation of antenna performance in the first frequency band, which is the low-band (LB).

[0089] As described above, changes in antenna performance may occur when the vehicle frame (9) is coupled with the glass panel (10) on which the antenna assembly (1000) is positioned. In this regard, FIG. 9 illustrates the electric field distribution when a signal is applied to the first radiating structure before being coupled with the metal frame. FIG. 10 illustrates the electric field distribution when a signal is applied to the first radiating structure after being coupled with the metal frame.

[0090] Referring to FIG. 9, an electric field distribution is shown when a signal is applied to a first radiating structure (1100-1) of an antenna assembly (1000) that is not coupled to a metal frame. The electric field distribution is higher in the first region (Rp1), which is the region where the first and third conductive patterns are arranged and the outer region of the flexible circuit board (1200), than in other surrounding regions.

[0091] Referring to FIG. 10, when a signal is applied to the first radiating structure (1100-1) of the antenna assembly (1000) combined with the frame (9) made of a metal material, the electric field distribution is shown to be higher in the area where the first and third conductive patterns are arranged and in the second area (Rp2) and the third area (Rp3) than in other peripheral areas. The electric field distribution in the second area (Rp2) is shown to be higher than in other peripheral areas due to the coupling between the frame (9) and the flexible circuit board (1200) that supplies power to the first radiating structure (1100-1). The electric field distribution in the third area (Rp3) is shown to be higher than in other peripheral areas due to the coupling to the second flexible circuit board (1200-2) of the second radiating structure (1100-2) by the electric field induced by the frame (9).

[0092] In this regard, since the ground pattern size of the grounded GCPW-fed FPCB is not sufficiently large, radiation occurs due to leakage current on the FPCB. When the antenna assembly (1000) is placed close to a frame (9) larger than the antenna due to radiation in the FPCB area, unwanted radiation may occur in the low band (LB). Accordingly, interference between MIMO antennas in the low band (LB) (700-960 MHz band) may increase due to leakage current generated in the metal frame (9) of the vehicle.

[0093] In order to prevent degradation of antenna performance, the flexible printed circuit board (1200) may be configured not to be placed in an area where the vehicle frame (9) extends. Meanwhile, this specification describes a transparent antenna structure that can prevent degradation of antenna performance even in a structure where the flexible printed circuit board (1200) overlaps an area where the vehicle frame (9) extends.

[0094] In order to prevent antenna performance degradation even in a structure where a flexible printed circuit board (1200) overlaps with an extended area of ​​a vehicle frame (9), a transparent antenna structure having an in-glass structure will be described with reference to FIGS. 6A to 8. A transparent electrode radiating structure of a broadband dipole structure with a length of half a wavelength (λg / 2) based on a first frequency band, which is a low band (LB), can be applied. When assembling to a vehicle glass panel (10), the influence of the vehicle's metal frame (9) that comes into close proximity to the feeding patterns (1210f, 1240f) must be reduced.

[0095] To this end, a feed pattern may be formed in a grounded coplanar waveguide (GCPW) structure in an area close to the frame (9). The GCPW structure is a structure in which an additional ground pattern is arranged in an upper area in the Z-axis direction in a coplanar waveguide (CPW) structure in which ground patterns are arranged on one side and the other side of the same plane as the feed patterns (1210f, 1240f). Meanwhile, the periphery of the transparent electrode-feed FPCB bonding portion may be implemented in a hybrid form of a CPW structure.

[0096] In particular, in order to improve radiation efficiency in the 5 to 6 GHz band, first and second slit structures (SL1, SL2) in the shape of a 'ㄷ' may be arranged on the conductive patterns of the flexible circuit board (1200) separately from the second and fifth conductive patterns (1120, 1150) in the shape of a triangular patch. In addition, in order to improve interference between 2X2 MIMO antennas, a structure in which a portion of the third and sixth conductive patterns (1130, 1160) facing each other and connected to the ground are cut diagonally may be applied.

[0097] Referring to FIGS. 5A to 8A, a glass assembly (200) according to the present specification will be described. The glass assembly (200) may be configured to include a glass panel (10) and an antenna assembly (1000).

Conductive patterns (1100) may be disposed inside the glass panel (10). Accordingly, the antenna assembly (1000) including the conductive patterns (1100) may be formed as an in-glass antenna structure, but is not limited thereto and may be changed depending on the application.

[0099] The first region (1100a) may include antenna elements configured to radiate a wireless signal. The second region (1100b) may be configured to include a grounded conductive pattern (1210g) and a feed pattern (1210f).

[0106] The size of the second conductive pattern (1120) may be formed smaller than the size of the third conductive pattern (1130). Accordingly, the antenna assembly (1000) may operate as a radiator in a higher frequency band by the second conductive pattern (1120).

One end of the second connection pattern (1230f) may be connected to the first power supply pattern (1210f) of the first CPW pattern (1210p). The other end of the second connection pattern (1230f) may be connected to the first connection pattern (1220f) of the second CPW pattern (1220p).

[0144] The second connection pattern (1230f) may include a first line portion (1231f), a second line portion (1232f), and / or an end portion (1233f). The end portion (1233f) of the second connection pattern (1230f) may correspond to the other end of the second connection pattern (1230f).

[0145] A second slot (1232s) with a pattern removed may be formed at the other end (1232) of the third ground pattern (1230g) corresponding to the shape of the end (1233f) of the second connection pattern (1230f). The area of ​​the second slot (1232s) may be greater than or equal to the area of ​​the end (1233f) of the second connection pattern (1230f).

[0146] Meanwhile, the flexible printed circuit board (1200) may be formed in a folded structure. The flexible printed circuit board (1200) may be formed in a folded structure in a third connection substrate portion (1230b) on which a third ground pattern (1230g) and a second connection pattern (1230f) are formed. The flexible printed circuit board (1200) may be formed in a folded structure based on the AA' line and the BB' line.

[0147] A flexible printed circuit board (1200) may have a first cable connection portion (1210c) having a second CPW pattern (1220p) formed thereon and may overlap a first antenna connection portion (1210) having a first CPW pattern (1210p) formed thereon. An overlapping area (1234) may be formed such that the ground pattern is removed so that the ground pattern is not disposed in an upper area of ​​the first feed pattern (1210f) of the first CPW pattern (1210p). Since the third ground pattern (1230g) of the second layer (1220b) does not overlap the first feed pattern (1210f), a reduction in radiation performance of an antenna operating in a wideband can be prevented and antenna efficiency can be improved.

[0148] Meanwhile, the first line portion (1231f) of the second connection pattern (1230f) may extend from one end of the second connection pattern (1230f) in the y-axis direction by a length that avoids the overlapping area (1234). The second line portion (1232f) may extend from the end of the first line portion (1231f) by a predetermined angle that avoids the overlapping area (1234) in the -x-axis direction. The third line portion (1233f) may extend from the end of the second line portion (1232f) in the y-axis direction by a length corresponding to the position of the first connection pattern (1220f) of the second CPW pattern (1220p). The end of the third line portion (1233f) may be connected to the end (1233f) of the second connection pattern (1230f).

[0149] It may be configured to include power supply patterns for each of a plurality of regions formed on a flexible printed circuit board (1200). In this regard, the flexible printed circuit board (1200) may include first to third power supply patterns (1210f, 1220f, 1230f) and first to third ground patterns (1211g, 1212g, 1221g, 1222g, 1230g).

[0150] Meanwhile, in a glass panel on which an antenna assembly according to the present specification is arranged, the glass panel may be formed as a double-laminated glass structure.

[0151] In addition, a vehicle equipped with an antenna assembly according to the present specification can improve antenna efficiency by forming a slit structure in the ground conductive pattern (1210g, 1240g). In this regard, FIG. 14 is an enlarged view of a ground conductive pattern having a slit structure formed in an antenna assembly according to the present specification.

[0152] Referring to FIGS. 8a, 8b, and 14, a slit structure may be formed in the ground conductive pattern (1210g, 1240g) of the second region (1100b) of the antenna assembly (1000). The slit structure may include a first slit structure (SL1) formed in the first ground conductive pattern (1210g) and a second slit structure (SL2) formed in the second ground conductive pattern (1240g).

The first slit structure (SL1) may be formed to face one side of a first power supply pattern (1210f).

The second slit structure (SL2) may be formed to face the other side of the second power supply pattern (1240f).

[0154] The first slit structure (SL1) may be formed by a first side (Sa1) and a second side (Sa2) in one axial direction and a third side (Sa3) in the other axial direction to form a dielectric region in the first ground conductive pattern (1210g). The first side (Sa1) may be formed to have a first slit length in the one axial direction. The second side (Sa2) may be formed to have a second slit length in the one axial direction. The third side (Sa3) may be formed to have a third slit length in the other axial direction perpendicular to the one axial direction. In this regard, the one axial direction may be the X-axis direction, which is a horizontal axial direction, and the other axial direction may be the Y-axis direction, which is a vertical axial direction.

[0155] The second slit length of the second side (Sa2) may be formed to be longer than the first slit length of the first side (Sa1). The second slit length of the second side (Sa2) may be formed in a range of 4 mm to 6 mm, so that the resonance frequency of the second conductive pattern (1120) may be formed to be 5 GHz or higher. The third slit length of the third side (Sa3) may be formed to be shorter than the first slit length of the first side (Sa1). The third slit length of the third side (Sa3) may be formed in a range of 1 mm to 2 mm, so that the resonance frequency of the second conductive pattern (1120) may be formed to be 5 GHz or higher.

[0156] The second slit structure (SL2) may be formed by a first side (Sb1) and a second side (Sb2) in one axial direction and a third side (Sb3) in the other axial direction to form a dielectric region in the second ground conductive pattern (1240g). The first side (Sb1) may be formed to have a first slit length in the one axial direction. The second side (Sb2) may be formed to have a second slit length in the one axial direction. The third side (Sb3) may be formed to have a third slit length in the other axial direction perpendicular to the one axial direction. In this regard, the one axial direction may be the X-axis direction, which is a horizontal axial direction, and the other axial direction may be the Y-axis direction, which is a vertical axial direction.

[0157] The second slit length of the second side (Sb2) may be formed to be longer than the first slit length of the first side (Sb1). The second slit length of the second side (Sb2) may be formed in a range of 4 mm to 6 mm, so that the resonance frequency of the fifth conductive pattern (1120) may be formed to be 5 GHz or higher. The third slit length of the third side (Sb3) may be formed to be shorter than the first slit length of the first side (Sb1). The third slit length of the third side (Sb3) may be formed in a range of 1 mm to 2 mm, so that the resonance frequency of the fifth conductive pattern (1120) may be formed to be 5 GHz or higher.

[0158] In this regard, FIG. 15 illustrates an electric field distribution in an antenna assembly having a slit structure according to the present specification. Specifically, FIG. 15(a) illustrates an electric field distribution at 5.5 GHz in a first radiating structure (1100-1) having a first slit structure (SL1). FIG. 15(b) illustrates an electric field distribution at 5.5 GHz in a first radiating structure (1100-2) having a second slit structure (SL2).

[0159] Meanwhile, Fig. 16 compares the reflection coefficient and antenna efficiency according to the presence or absence of a slit structure in the ground conductive pattern of the second region formed by the flexible circuit board. Fig. 16(a) compares the reflection coefficient according to the presence or absence of a slit structure in the ground conductive pattern of the second region formed by the flexible circuit board. Fig. 16(a) compares the antenna efficiency according to the presence or absence of a slit structure in the ground conductive pattern of the second region formed by the flexible circuit board.

[0160] Referring to FIGS. 8A to 15, in an antenna assembly (1000) having a first slit structure (SL1), the electric field distribution in the peripheral area (Rp) of the second conductive pattern (1120) formed as a triangular patch has a higher value than the electric field distribution in other areas. Therefore, in the third frequency band, the second conductive pattern (1120) formed as a triangular patch and the first slit structure (SL1) operate as a radiator. Accordingly, the antenna efficiency of the structure in which the second conductive pattern (1120) and the slit structure (SL) operate as a radiator is further increased than the structure in which a signal is radiated only by the second conductive pattern (1120).

[0161] In an antenna assembly (1000) having a second slit structure (SL2), the electric field distribution in the peripheral area (Rpb) of the fifth conductive pattern (1120) formed as a triangular patch has a higher value than the electric field distribution in other areas. Therefore, in the third frequency band, the fifth conductive pattern (1150) formed as a triangular patch and the second slit structure (SL2) operate as radiators. Accordingly, the antenna efficiency of the structure in which the fifth conductive pattern (1150) and the second slit structure (SL2) operate as radiators is increased more than the structure in which the signal is radiated only by the second conductive pattern (1120).

[0162] In the third and sixth conductive patterns (1130, 1160) connected to the ground pattern, the upper corner portion (CR1) having the largest electric field strength in the low band (LB) can be removed to a predetermined length. Accordingly, the isolation between antennas can be improved without reducing antenna efficiency. In this regard, the upper corner portion (CR1) of the third and sixth conductive patterns (1130, 1160) can be removed to a predetermined length of 0.1 to 0.2 λg based on 800 MHz in the low band (LB).

[0163] Referring to FIGS. 8 to 15 and 16(a), it can be seen that the reflection coefficient of the antenna assembly (1000) having a slit structure is improved more than the reflection coefficient of the antenna assembly (1000b) without a slit structure. Specifically, it can be seen that the reflection coefficient of the antenna assembly (1000) having a slit structure is improved more in the frequency band of 5-6 GHz. In particular, the reflection coefficient of the antenna assembly (1000) having a slit structure has a value of -20 dB or less at the center frequency of 5.5 GHz.

[0164] Referring to FIGS. 8 to 15 and 16(b), it can be seen that the antenna efficiency of the antenna assembly (1000) having a slit structure is improved more than that of the antenna assembly (1000b) without a slit structure. Specifically, it can be seen that the antenna efficiency of the antenna assembly (1000) having a slit structure is improved more in the frequency band of 5-6 GHz. In particular, the antenna efficiency of the antenna assembly (1000) having a slit structure at the center frequency of 5.5 GHz has a value of -2.49 dBi. The antenna efficiency of the antenna assembly (1000b) without a slit structure at the center frequency of 5.5 GHz is -2.92 dBi. Accordingly, the first slit structure (SL1) may be formed in the first ground conductive pattern (1210g) or the second slit structure (SL2) may be formed in the second ground conductive pattern (1240g) to improve the antenna efficiency by 0.43 dB.

[0165] Meanwhile, the plurality of conductive patterns of the antenna assembly according to the present specification can operate as radiators in different frequency bands. Referring to FIGS. 8 to 15, the plurality of conductive patterns operating as radiators in different frequency bands will be described.

[0166] The first conductive pattern (1110) and the third conductive pattern (1130) may be formed to operate in a dipole antenna mode in a first frequency band of 617 to 960 MHz. The first conductive pattern (1110) and the third conductive pattern (1130) may be formed to radiate a wireless signal in the first frequency band. The fourth conductive pattern (1140) and the sixth conductive pattern (1160) may be formed to operate in a dipole antenna mode in the first frequency band. The fourth conductive pattern (1140) and the sixth conductive pattern (1160) may be formed to radiate a wireless signal in the first frequency band. Although the first frequency band may be set to 617 to 960 MHz, it is not limited thereto and may be changed according to the application.

[0167] In this regard, since the third conductive pattern (1130) and the sixth conductive pattern (1160) operate as radiators in the first frequency band, interference between the first and second radiating structures (1100-1, 1100-2) can be determined according to the distance between the third conductive pattern (1130) and the sixth conductive pattern (1160). It is necessary to maintain the interference between the first and second radiating structures (1100-1, 1100-2) below a certain level without increasing the overall size of the antenna assembly (1000). To this end, interference can be reduced by removing the corner of the upper area of ​​the first surface (S1) of the third conductive pattern (1130) and the corner of the upper area of ​​the second surface (S2) of the sixth conductive pattern (1160).

[0168] The horizontal length (HL1) and the vertical length (VL1) of the edge of the upper region of the first side (S1) of the third conductive pattern (1130) operating in the first frequency band may be formed to have the same length. The horizontal length (HL1) and the vertical length (VL1) of the edge of the upper region of the first side (S1) may be formed to have a range between 0.1 and 0.2 wavelengths (λg). The horizontal length (HL1) and the vertical length (VL1) of the second gap region (GR2) of the first side (S1) of the third conductive pattern (1130) operating in the first frequency band may be formed to have the same length. The horizontal length (HL1) and the vertical length (VL1) of the second gap region (GR2) of the first side (S1) may be formed to have a range between 0.1 and 0.2 wavelengths (λg).

[0169] The horizontal length (HL2) and the vertical length (VL2) of the edge of the upper region of the second surface (S2) of the sixth conductive pattern (1130) operating in the first frequency band may be formed to have the same length. The horizontal length (HL2) and the vertical length (VL2) of the edge of the second gap region (GR2) of the second surface (S2) may be formed to have a range between 0.1 and 0.2 wavelengths (λg). The horizontal length (HL2) and the vertical length (VL2) of the second gap region (GR2) of the second surface (S2) of the sixth conductive pattern (1130) operating in the first frequency band may be formed to have the same length. The horizontal length (HL2) and the vertical length (VL2) of the edge of the upper region of the second surface (S2) may be formed to have a range between 0.1 and 0.2 wavelengths (λg).

[0170] In this regard, Fig. 17 shows the electric field distribution depending on whether the upper regions of the third and sixth conductive patterns are edge-removed. Fig. 17(a) shows the electric field distribution in a structure in which the upper regions of the third and sixth conductive patterns (1130, 1160) are edge-removed. Fig. 17(a) shows the electric field distribution in a structure in which the upper regions of the third and sixth conductive patterns (1130, 1160) are edge-removed.

[0171] Referring to Fig. 17(a), in the second structure where the upper edges of the third and sixth conductive patterns are not removed, the electric field distribution in the corner region (R1a) has a value above a certain level. Accordingly, the interference level between the third and sixth conductive patterns may increase in the first frequency band.

[0172] Referring to FIGS. 8 and 17(b), in the third structure where the corners of the upper regions of the third and sixth conductive patterns are removed, the electric field distribution in the corner regions (R2a, R2b) has a value below a certain level. Accordingly, the interference level between the third and sixth conductive patterns (1130, 1160) in the first frequency band can be reduced. Accordingly, the interference level between the first and second radiating structures (1100-1, 1100-2) can be reduced when the first and second radiating structures (1100-1, 1100-2) are in multiple input / output (MIMO) operation.

[0173] In this regard, FIG. 18 illustrates an isolation diagram between the first and second radiating structures of the antenna assembly according to embodiments. Referring to FIGS. 6A to 10 and FIG. 18, the isolation diagram between the first and second radiating structures of the antenna assembly according to embodiments will be described.

[0174] (i) The antenna assembly of the first structure is a structure in which the upper edge areas of the third and sixth conductive patterns are not removed, so that the third and sixth conductive patterns have the same spacing area. (ii) The antenna assembly of the second structure is a structure in which the antenna assembly of the first structure is combined with a metal frame of the vehicle. The antenna assemblies of the first and second structures are structures in which the upper edge areas of the third and sixth conductive patterns are not removed, so that the third and sixth conductive patterns have the same spacing area.

[0175] (i) In the first structure where the antenna assembly is not coupled to the frame, the isolation between the first and second radiating structures is -16.92 dB at 0.82 GHz. (ii) In the second structure where the antenna assembly is coupled to the frame and the corners of the upper region are not removed, the isolation between the first and second radiating structures deteriorates to -12.55 dB at 0.82 GHz.

[0176] Referring to FIGS. 8a and 9, (iii) the antenna assembly of the third structure is a structure in which the upper edge areas of the third and sixth conductive patterns (1130, 1160) are removed to form a second gap area (GR2). The antenna assembly of the third structure is a structure that is not coupled to the metal frame of the vehicle, similar to the first structure.

[0177] Referring to FIGS. 8b and 10, (iv) the antenna assembly of the fourth structure is a structure in which the upper edge areas of the third and sixth conductive patterns (1130, 1160) are removed to form a second gap area (GR2). The antenna assembly of the fourth structure is a structure combined with a frame (9) made of a metal material, similar to the second structure.

[0178] (iii) The third structure, in which the upper corner regions of the third and sixth conductive patterns (1130, 1160) are removed, has an isolation of -18.74 dB at 0.82 GHz between the first and second radiating structures (1100-1, 1100-2). Comparing the first and third structures, the isolation is improved by approximately 1.8 dB from -16.92 dB to -18.74 dB by removing the upper corner regions of the third and sixth conductive patterns (1130, 1160). Therefore, even in a glass assembly structure that is not combined with a metal frame, the isolation can be improved by forming a second gap region (GR2) by removing the upper corner regions of the third and sixth conductive patterns (1130, 1160).

[0179] (iv) The third structure, in which the upper edge areas of the third and sixth conductive patterns (1130, 1160) are removed, has an isolation of -18.36 dB between the first and second radiating structures (1100-1, 1100-2) at 0.82 GHz. Comparing the second and fourth structures, the isolation is improved by approximately 5.8 dB from -12.55 dB to -18.36 dB by removing the upper edge areas of the third and sixth conductive patterns (1130, 1160). Therefore, in the glass assembly structure combined with the metal frame, the isolation can be significantly improved by forming the second gap area (GR2) by removing the upper edge areas of the third and sixth conductive patterns (1130, 1160). In particular, in a situation where the isolation is deteriorated to -15 dB or more by a metal frame, the isolation can be significantly improved by removing the upper corner areas of the third and sixth conductive patterns (1130, 1160).

[0180] Meanwhile, the operation of the antenna assembly (1000) according to the present specification in the second and third frequency bands will be described with reference to FIGS. 8a to 16.

[0181] The first conductive pattern (1110) may be configured to operate in a monopole antenna mode in a second frequency band higher than the first frequency band. The fourth conductive pattern (1130) may be configured to operate in a monopole antenna mode in the second frequency band. The second frequency band may be set to 1520 to 4500 MHz, but is not limited thereto and may be changed depending on the application.

[0182] The second conductive pattern (1120) may be formed as a transparent electrode pattern of a triangular patch having a first length (La1) and a second length (La2) on one axis and another axis perpendicular to the first axis. The second conductive pattern (1120) formed as a triangular patch having a first length (La1) and a second length (La2) may be configured to radiate a signal in a third frequency band higher than the second frequency band. The third frequency band may be set to 4500 to 6000 MHz, but is not limited thereto and may be changed depending on the application. The first length (La1) and the second length (La2) of the second conductive pattern (1120) may be determined within a predetermined range based on λg / 4 of the wavelength (λg) of the center frequency of the third frequency band.

[0183] The fifth conductive pattern (1150) may be formed as a transparent electrode pattern of triangular patches having a first length (Lb1) and a second length (Lb2) on one axis and another axis perpendicular to the first axis. The fifth conductive pattern (1150) formed as triangular patches having a first length (Lb1) and a second length (Lb2) may be configured to radiate a signal in a third frequency band higher than the second frequency band. The first length (Lb1) and the second length (Lb2) of the fifth conductive pattern (1150) may be determined within a predetermined range based on λg / 4 of the wavelength (λg) of the center frequency of the third frequency band.

[0184] The above describes a glass assembly having an antenna assembly and a vehicle equipped with the same. The technical effects of the glass assembly having an antenna assembly and the vehicle equipped with the same are as follows.

[0185] According to the present specification, the isolation between antennas in an antenna assembly implemented with a transparent material can be improved by changing the shapes of adjacent conductive patterns in a plurality of radiating structures.

[0186] According to the present specification, the shape of adjacent conductive patterns in a plurality of radiating structures can be changed, thereby improving the isolation between the plurality of radiating structures of a transparent antenna assembly when the plurality of radiating structures are arranged adjacently.
