[0070] The vehicle window glass member 100 may be a windshield on a vehicle, such as a front windshield, a rear windshield or a side windshield, and the vehicle window glass member 100 may include a plurality of shielding areas located at the edge of the vehicle window glass member 100, and the first shielding area 110 may be a shielding area located at the lower area of ​​the vehicle window glass member 100. Optionally, the vehicle window glass member 100 may be a laminated glass, including 3.0 white wave + PVB + 3.0 white wave, the main component of which is silicon, and the material is stable. The antenna body of the antenna assembly 200 may be metallic silver, which has excellent conductive properties.

[0071] The antenna assembly 200 includes a plurality of antenna sets 210.

The V2X (vehicle to everything) antenna is an antenna for realizing information exchange between the vehicle and the outside world, and can realize information exchange between the vehicle and surrounding vehicles, pedestrians, infrastructure, and networks.

[0072] Since the antennas in each antenna set 210 have different operating frequency bands, the first antenna 211, the second antenna 212 and the vehicle network V2X antenna 213 are arranged at intervals, and the antenna layouts are spaced a certain distance apart to avoid mutual interference of antenna signals.

In this way, each antenna set is arranged at intervals, and the antennas in each antenna set are also arranged at intervals in the first shielding area of ​​the vehicle window glass member. Antennas of different working frequency bands are spaced a certain distance apart, and will not generate signal interference with each other, so the antenna isolation is better and the antenna performance is higher.

[0074] Furthermore, arranging the plurality of antennas in the first shielding area does not affect the transparency of the glass member of the vehicle, thereby not affecting the field of vision of the driver in the vehicle.

[0075] In one embodiment, Figure 2 As shown, the multiple antenna sets 210 include a first antenna set 210A and a second antenna set 210B; the first antenna set 210A and the second antenna set 210B are symmetrically arranged relative to the center line 120 of the vehicle window glass piece 100 in the first direction; the antennas in the first antenna set 210A and the second antenna set 210B are all spaced apart along the first direction.

[0076] The first direction may be a horizontal direction, the center line 120 divides the vehicle window glass member 100 into left and right sides, and the first antenna set 210A and the second antenna set 210B are respectively located on the left and right sides of the center line 120 .

The antennas in the second antenna set 210B are arranged at intervals, and the V2X antenna 213, the second antenna 212, and the first antenna 211 are arranged in sequence from the center line 120 of the vehicle window glass 100 to the edge of the vehicle window glass. Optionally, the edge of the vehicle window glass 100 can be the upper edge or the lower edge. In this embodiment, the lower edge is used as an example for description.

The first antenna 211 and the second antenna 212 have wide antenna coverage bandwidth.

[0080] The first antenna 211 in the first antenna set 210A and the second antenna set 210B can be a 5G main antenna and a 5G secondary antenna respectively.

[0081] In one embodiment, Figure 3 As shown, the V2X antenna 213 includes a rectangular radiator 31, and the rectangular radiator 31 includes a slot structure 32 in the middle, and the slot structure 32 includes at least one of a U-shape, a semicircular ring and a semi-elliptical ring.

[0082] Among them, the overall size of the slot structure 32 can be a wavelength of the center frequency of the working frequency band 5900-5930MHz of the V2X antenna 213 under the glass medium, the feeding position is at both ends of the slot structure 32, the outer size of the V2X antenna 213 can be 32*30mm, and the antenna size is relatively small.

[0083] In the examples of this application, please refer to Figure 4 The first antenna 211 includes a first radiation branch 41, a second radiation branch 42 and a third radiation branch 43; the first radiation branch 41 is connected to the second radiation branch 42 and the third radiation branch 43; the first radiation branch 41 is a U-shaped structure, and the second radiation branch 42 and the third radiation branch 43 are L-shaped structures.

[0084] Optionally, the sum of the length of the first side of the first radiation branch 41 and the length of the first side of the second radiation branch 42 is a first ratio of the wavelength of the center frequency point in the 619-960MHz frequency band in the glass medium; the sum of the length of the first side of the second radiation branch 42 and the length of the first side of the third radiation branch 43 is a second ratio of the wavelength of the center frequency point in the 1710-2690MHz frequency band in the glass medium; the sum of the length of the second side of the second radiation branch 42 and the length of the first side of the third radiation branch 43 is a third ratio of the wavelength of the center frequency point in the 3300-3800MHz frequency band in the glass medium.

[0085] The outer dimensions of the first antenna 211 may be 90*55 mm. The first side of the first radiating branch 41 may be the side where the first radiating branch 41 and the second radiating branch 42 are connected, the first side of the second radiating branch 42 may be the long side of the second radiating branch 42, and the first ratio is one-fourth. The first side of the third radiating branch 43 may be the long side of the third radiating branch 43, and the second ratio is one-fourth. The second side of the second radiating branch 42 may be the short side of the second radiating branch 42, and the third ratio is one-fourth. Figure 4 As shown, the feeding position is between the first width 421 of the second radiation branch 42 and the second width 431 of the third radiation branch 43. The distance between the two is relatively close, and the gap forms a capacitance effect that is beneficial to expanding the bandwidth; the length of the first width 421 and the second width 431 combined is about one-fourth of the wavelength of the central frequency of 4400-5000MHz under the glass medium. The U-shaped first radiation branch 41, the L-shaped second radiation branch 42 and the third radiation branch 43 form a loop structure.

[0086] In the above embodiment, the first antenna 211 forms a short-circuit grounding structure in structure, which is similar to the short-circuit structure formed at both ends of the PIFA (Planar Inverted F-shaped Antenna, picofarad antenna) antenna feed, which is conducive to the realization of the antenna in-place detection function.

[0087] Optionally, the second antenna 212 includes a fourth radiation branch, a fifth radiation branch and a sixth radiation branch; the fourth radiation branch is connected to the fifth radiation branch and the sixth radiation branch; the fourth radiation branch is a U-shaped structure, and the fifth radiation branch and the sixth radiation branch are an L-shaped structure.

[0088] The second antenna 212 has the same structure as the first antenna 211, wherein the length of the first side of the fifth radiation branch is less than the length of the first side of the second radiation branch 42. The long side of the low-frequency "L"-shaped second radiation branch 42 of the first antenna 211 is shortened to remove its low-frequency resonance, leaving only the mid- and high-frequency bands. Therefore, the resonant frequencies are 1710-2690MHz, 3300-3800MHz and 4800-5000MHz, the antenna has a wide coverage bandwidth, and the gain is relatively high. Optionally, at 1710-2690MHz, the average gain is >3dBi, at 3300-3800MHz, the average gain is >4dBi, and at 4800-5000MHz, the average gain is >4dBi. The outer dimensions of the second antenna 212 are 80*55mm.

[0089] Optionally, the structures of the first antenna and the second antenna may also be as follows: Figure 5 shown.

[0090] In the above embodiment, the structure of the first antenna and the second antenna can increase the antenna coverage bandwidth, and the antenna gain is high.

[0091] In one embodiment, Figure 6 As shown, the antenna assembly 200 further includes an AM / FM antenna 220 . The AM / FM antenna 220 is disposed in the second shielding area 130 of the vehicle window glass. The second shielding area 130 is disposed opposite to the first shielding area 110 .

[0092] Among them, the second shielding area 130 can be a shielding area located above the window glass 100. The AM / FM antenna 220 is an active glass antenna and needs to be used in combination with an LNA (Low-noise Amplifier). The gain of the LNA in each frequency band is 7.5dB for AM and 8dB for FM. The LNA position needs to be considered when designing the AM / FM antenna 220, and the printing position of the AM / FM antenna 220 is planned. The antenna body of the AM / FM antenna 220 is made of silver, and the silver paste is printed on the window glass 100 as a conductive medium. By adjusting the length, number or interval between different silver paste lines, the bandwidth, impedance, radiation direction, or receiving direction of the AM / FM antenna 220 can be adjusted. Optionally, the AM / FM antenna 220 is a monopole antenna structure with a printed silver paste pattern as a radiating oscillator, and the body sheet metal is used as a radiation ground. The grounding is achieved by connecting the amplifier shell and the body sheet metal; the resonant frequency of the AM / FM antenna 220 is formed by different branching methods. Among them, the FM antenna frequency is 87-108MHz; the AM antenna frequency is 520KHz~1710KHz.

[0093] In the above embodiment, the AM / FM antenna is printed on the window glass instead of being placed externally on the front of the vehicle, which will not affect the appearance of the commercial vehicle.

[0094] Optional, such as Figure 7 As shown, the AM / FM antenna 220 includes a first horizontal branch 61, a second horizontal branch 62, a third horizontal branch 63, a fourth horizontal branch 64, a fifth horizontal branch 68, a sixth horizontal branch 69, a first vertical branch 65, a second vertical branch 66 and a third vertical branch 67; the sum of the length of the first horizontal branch 61 and the length of the second horizontal branch 62 is the fourth ratio of the wavelength of the resonant frequency of FM in the glass medium; the sum of the length of the third horizontal branch 63 and the length of the fourth horizontal branch 64 is the fifth ratio of the wavelength of the resonant frequency of AM in the glass medium; the first vertical branch 65 divides the third horizontal branch 63 and the fourth horizontal branch 64 into two halves; and a plurality of second vertical branches 66 and a sixth horizontal branch 69 are included between the first vertical branch 65 and the third vertical branch 67.

[0095] Among them, the fourth ratio can be one-fourth, and the fifth ratio can be one-fourth. That is, the sum of the length of the first horizontal branch 61 and the length of the second horizontal branch 62 is one-fourth of the wavelength of the resonant frequency of FM in the glass medium; the sum of the length of the third horizontal branch 63 and the length of the fourth horizontal branch 64 is one-fourth of the wavelength of the resonant frequency of AM in the glass medium. The first vertical branch 65 divides the third horizontal branch 63 and the fourth horizontal branch 64 equally, so that the length of the fourth horizontal branch 64 and the third horizontal branch 63 are the same, which is equivalent to adding an additional FM frequency branch. The fifth horizontal branch 68 does not form any connection with other branches, thereby forming a coupled resonance, which is conducive to expanding the FM antenna bandwidth and antenna direction synthesis, so that the linear average gain is improved. One or more second vertical branches 66 and sixth horizontal branches 69 can be used between the first vertical branch 65 and the third vertical branch 67 to divide the area equally, thereby increasing the current path of the AM frequency and forming a coupled current path to expand the antenna bandwidth of AM.

[0099] Among them, the window glass component 100 is combined with the sheet metal design, and the sheet metal and the window glass component 100 form a first angle, such as a 60° angle, which is conducive to reflecting the electromagnetic waves generated by the antenna assembly 200 to the outside of the vehicle; the V2X antenna 213 is entirely above the sheet metal, and the sheet metal directly radiates electromagnetic waves; a small part of the first antenna 211 and the second antenna 212 overlaps with the sheet metal, and the first antenna 211 and the second antenna 212 are not in direct contact with the sheet metal, so that the first antenna 211 and the second antenna 212 are coupled with the sheet metal, and the current generated by the first antenna 211 and the second antenna 212 is coupled to the metal sheet metal, forming a current on the sheet metal to form radiation.

[0100] In the embodiments of the present application, Figure 8 As shown, the above antenna glass assembly is applied to a commercial vehicle. Figure 8 The layout diagram of the front windshield of a commercial vehicle is shown in FIG. 5G main and 5G auxiliary are two first antennas, 5G-MIMO1 and 5G-MIMO2 are two second antennas, and V2X-1 and V2X-2 are two V2X antennas. The specific structure of each antenna can be as follows: Fig. 9 As shown in the figure, from left to right are the 5G main antenna, 5G-MIMO1 antenna, V2X-1 antenna, V2X-2 antenna, 5G-MIMO1 antenna and 5G sub-antenna, each antenna is connected to the vehicle central control terminal through a connector. Among them, the standing waves of the 5G main and sub antennas are as follows: Fig.10 5G-MIMO antenna standing wave Fig.115G antenna isolation is shown in Fig.12 As shown in the figure, the red solid line is the isolation between the 5G main antenna and the 5G secondary antenna, the purple dotted line is the isolation between the 5G main antenna and the 5G-mimo1 antenna, the blue dotted line is the isolation between the 5G main antenna and the 5G-mimo2 antenna, the purple dotted line is the isolation between the 5G secondary antenna and the 5G-mimo1 antenna, the green dotted line is the isolation between the 5G secondary antenna and the 5G-mimo2 antenna, and the pink dotted line is the isolation between the 5G mimo1 antenna and the 5G-mimo2 antenna. Antenna gain is as shown in the figure. Fig.13 As shown, the average gain is the average of the horizontal polarization gain and the vertical polarization gain. Generally, the average gain is required to be greater than -9dB.

[0101] In the above embodiment, the antenna assembly is arranged in the shielding area below the front windshield of the vehicle, which does not affect the transparent area of ​​the glass and does not block the driver's field of vision. At the same time, the multiple antennas in the antenna assembly are arranged in a left-right symmetrical layout. From the driver's perspective, the front windshield is the 5G main antenna, the 5G MIMO antenna and the V2X antenna from the left side in sequence. The antenna layout avoids the metal wiper position to prevent the metal wiper from affecting the antenna. It can be understood that the front windshield in this embodiment can be applied to various vehicles. This application is illustrated by a commercial vehicle. Under normal circumstances, the horizontal width of the front windshield of a commercial vehicle is usually 2 meters, and the shielding area size is large enough, so that the antenna layout is very flexible and better isolation can be obtained; the AM / FM antenna is arranged in the shielding area above the front windshield. The antenna is hidden in the shielding area, does not affect the transparent area of ​​the glass, and does not block the driver's field of vision. In this way, the high-frequency antenna (5G+V2X) and the low-frequency antenna (AM / FM) are arranged in different areas, so that there is no signal interference between the two, which is conducive to the improvement of the overall antenna performance.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described.
