Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a window module and a vehicle. Background Technology

[0002] With the continuous development of intelligent technology, car windows are integrating antennas to enable communication with the outside world. However, the traditional structure of in-window antennas is complex, resulting in a low yield rate for window modules and making mass production difficult. Summary of the Invention

[0003] Based on this, to address the problems of complex antenna structure, low yield, and difficulty in mass production of vehicle window modules, a vehicle window module and vehicle are provided.

[0004] The technical solution is as follows:

[0005] On the one hand, this application provides a vehicle window module, including:

[0006] A first glass, a second glass, and a connecting layer, wherein the connecting layer is disposed between the first glass and the second glass to connect the first glass and the second glass into one piece;

[0007] The antenna includes a transmitting antenna and a receiving antenna. Both the transmitting antenna and the receiving antenna include a first radiating arm, a second radiating arm, and a feeding network. The first radiating arm and the second radiating arm are electrically connected to the feeding network. The first radiating arm is disposed between the connecting layer and the first glass, and the second radiating arm is disposed between the connecting layer and the second glass.

[0008] In the aforementioned window module, the connecting layer integrates the first and second glass panes. A first radiating arm and a second radiating arm are sandwiched between the first and second glass panes and fed by a power supply network. A transmitting antenna and a receiving antenna enable the window module to transmit and receive signals. During assembly, the first radiating arm is positioned between the first glass pane and the connecting layer, and the second radiating arm is positioned between the second glass pane and the connecting layer, followed by lamination. This process is simple, and the first and second radiating arms are located on opposite sides of the connecting layer, preventing short circuits due to mutual conduction. This results in a high yield rate and suitability for mass production, meeting practical needs. Furthermore, the fact that the first and second radiating arms are positioned on different sides of the connecting layer allows for adjustments to the distance between the radiating arms and the antenna center, as well as changes to the length of the radiating arms themselves, thereby increasing the antenna's center frequency range and broadening its application scope.

[0009] The technical solution will be further explained below:

[0010] In one embodiment, both the first radiating arm and the second radiating arm are arranged in a strip shape. The first radiating arm has two arms arranged in parallel with a gap between them, and the second radiating arm has two arms arranged in parallel with a gap between them. The extension direction of the second radiating arm is different from the extension direction of the first radiating arm.

[0011] In one embodiment, when projecting along the thickness direction of the second glass, the first radiating arm forms a first projection body, the second radiating arm forms a second projection body, and the second projection body and the first projection body are alternately arranged to form a ring structure.

[0012] In one embodiment, the first glass has opposing first and second surfaces, the second glass has opposing third and fourth surfaces, and the connecting layer is disposed between the second surface and the third surface;

[0013] The first radiating arm includes a first radiating conductor arranged in a strip shape, which is disposed on the second surface; the second radiating arm includes a second radiating conductor arranged in a strip shape, which is disposed on the third surface.

[0014] In one embodiment, at least two first radiating conductors are provided and spaced apart and parallel to each other on the second surface. The first radiating arm also includes a first wiring conductor, which is electrically connected to the feed network and connects all the first radiating conductors.

[0015] The second radiating conductor is provided in at least two and is arranged parallel to each other at intervals on the third surface. The second radiating arm also includes a second wiring conductor, which is electrically connected to the feed network and connects all the second radiating conductors.

[0016] In one embodiment, at least one of the first radiating conductor, the first connecting conductor, the second radiating conductor, and the second connecting conductor is an enameled wire.

[0017] In one embodiment, the antenna further includes a first feed conductor and a second feed conductor; the first feed conductor is electrically connected to the first wiring conductor, the second feed conductor is electrically connected to the second wiring conductor, and both the first feed conductor and the second feed conductor are electrically connected to the feed network.

[0018] In one embodiment, the window module further includes a transmitter and a receiver, the transmitter being electrically connected to the transmitting antenna and the receiver being electrically connected to the receiving antenna.

[0019] In one embodiment, a power divider is provided between the transmitter and the transmitting antenna; or / and a combiner is provided between the receiver and the receiving antenna.

[0020] On the other hand, this application also provides a vehicle including a window module as described in any of the above technical solutions.

[0021] The aforementioned vehicle includes the aforementioned window module, which can be a sunroof module or a front window module, etc. A connecting layer connects the first glass and the second glass into one unit. The first radiating arm and the second radiating arm are sandwiched between the first glass and the second glass and are fed through a power supply network. The transmitting antenna and the receiving antenna enable the window module to transmit and receive signals. During assembly, the first radiating arm is arranged between the first glass and the connecting layer, and the second radiating arm is arranged between the second glass and the connecting layer, and then the pieces are joined together. The process is simple, and the first and second radiating arms are located on opposite sides of the connecting layer, avoiding short circuits caused by mutual conduction. The yield rate is high, and it is suitable for mass production, meeting practical needs. At the same time, the first and second radiating arms are arranged on different sides of the connecting layer, and the center frequency range of the antenna can be increased by changing the distance of the radiating arm from the antenna center and the length of the radiating arm itself, thus expanding the application range.

Detailed Implementation

[0033] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings:

[0034] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] With the continuous development of intelligent technology, vehicles (such as electric vehicles or gasoline vehicles) are gradually being equipped with components such as antennas to communicate with the outside world, thereby improving vehicle convenience and other performance aspects. To save space, antennas can be placed inside the windows, such as in the sunroof module, front window module, rear window module, or side window module. For easier placement within the window module, the antenna is often designed as a clip-on antenna to minimize space usage.

[0036] Circularly polarized antennas have broad application prospects in communications, radar, telemetry and remote sensing, electronic jamming, and electronic reconnaissance. There is also considerable research and discussion on the implementation and performance of circularly polarized antennas. During the implementation process, the applicant discovered that there are many methods to increase the directivity of circularly polarized antennas. In principle, they can be mainly divided into the following two types:

[0037] The first method involves using multiple directional, circularly polarized antenna elements arranged in an appropriate combination. Each antenna element's radiation covers a specific azimuth angle, and the increased circular polarization directionality within the radiation plane is achieved through the superposition of the radiation from multiple antenna elements.

[0038] The second method is to use an omnidirectional radiating antenna. These antennas are mostly linearly polarized, but can achieve omnidirectional circular polarization by feeding in circularly polarized waves or by using other means such as adding parasitic radiating elements.

[0039] However, the applicant further discovered:

[0040] In the first implementation method, it is necessary to first design a circularly polarized antenna element that meets the requirements, then design an appropriate parallel feeding network, and then combine the designed circularly polarized antenna elements in a certain way to ensure that the phase and amplitude of the radiated waves of each circularly polarized antenna element are consistent. Finally, the directivity of the circularly polarized antenna is increased by superimposing the radiation of each antenna element in the radiating surface. Although this type of antenna can take into account multiple performance aspects, it often requires the use of microstrip antennas. Microstrip antennas have limited bandwidth, which needs to be increased through broadband methods. At the same time, this type of antenna is generally difficult to form into a large antenna array, the gain of a single antenna is low, and it is difficult to meet the practical requirements in applications. In addition, the presence of the feeding network also makes the antenna design more complex.

[0041] In the second implementation method, the antenna size is relatively large, making it difficult to miniaturize and achieve multiple functions such as polarization reconfiguration and multi-band operation. Furthermore, due to the presence of numerous small parasitic elements and other loading devices, the processing is more complex and the manufacturing cost is high.

[0042] Please refer to Figure 1 and Figure 2 The illustrated embodiment provides a vehicle window module, including a first glass 110, a second glass 120, a connecting layer 130, and an antenna. The connecting layer 130 connects the first glass 110 and the second glass 120 to form an integral or composite structure. At least a portion of the antenna is sandwiched between the first glass 110 and the second glass 120. Two antennas can be provided, serving as a transmitting antenna 201 and a receiving antenna 202, respectively. Alternatively, three or a fourth antenna can be provided; the number is not limited here.

[0043] like Figure 1 and Figure 2 As shown, the connecting layer 130 is disposed between the first glass 110 and the second glass 120 so that the first glass 110 and the second glass 120 are connected as one unit.

[0044] Optionally, the connecting layer 130 is a PVB layer. PVB stands for polyvinyl butyral. For example, the first glass 110 and the second glass 120 are bonded together by the PVB adhesive layer, and the first radiating arm 210 and the second radiating arm 220 are bonded between the first glass 110 and the second glass 120.

[0045] Of course, the connecting layer 130 can also be other polymer films. For example, the material of the connecting layer 130 can be: ethylene vinyl acetate, polyurethane, polypropylene, polyacrylate, polyethylene, polycarbonate, polymethyl methacrylate, polyvinyl chloride, polyacetal resin, casting resin, acrylate, fluorinated ethylene propylene, polyvinyl fluoride and / or ethylene tetrafluoroethylene and / or mixtures and / or copolymers thereof.

[0046] like Figure 1 and Figure 2 As shown, the antenna includes a transmitting antenna 201 and a receiving antenna 202. Both the transmitting antenna 201 and the receiving antenna 202 include a first radiating arm 210, a second radiating arm 220 and a feeding network. The first radiating arm 210 and the second radiating arm 220 are electrically connected to the feeding network. The first radiating arm 210 is disposed between the connecting layer 130 and the first glass 110, and the second radiating arm 220 is disposed between the connecting layer 130 and the second glass 120.

[0047] Optionally, the transmitting antenna 201 and the receiving antenna 202 are located on opposite sides of the connecting layer 130, and are both embedded inside the corresponding first glass 110 and second glass 120 or sandwiched between the first glass 110 and the second glass 120. The transmitting antenna 201 and the receiving antenna 202 are both located on the same side of the first glass 110 or the same side of the second glass 120.

[0048] like Figure 1 and Figure 2 From the perspective shown, the first radiating arm 210 is located on the upper side of the connecting layer 130, and the second radiating arm 220 is located on the lower side of the connecting layer 130. This arrangement can prevent accidental short circuits caused by the first radiating arm 210 and the second radiating arm 220, thereby improving the yield.

[0049] This window module can be applied to vehicles, such as a sunroof module or a front window module. The connecting layer 130 connects the first glass 110 and the second glass 120 into one unit. The first radiating arm 210 and the second radiating arm 220 are sandwiched between the first glass 110 and the second glass 120 and are fed through a power supply network. The transmitting antenna 201 and the receiving antenna 202 enable the window module to transmit and receive signals. During assembly, the first radiating arm 210 is placed between the first glass 110 and the connecting layer 130, and the second radiating arm 220 is placed between the second glass 120 and the connecting layer 130. Then, they are joined together. The process is simple, and the first radiating arm 210 and the second radiating arm 220 are located on opposite sides of the connecting layer 130, avoiding short circuits caused by mutual conduction. The yield rate is high, and it is suitable for mass production, meeting practical needs.

[0050] The circular polarization performance of an antenna is related to the distance of the radiating arm from the antenna center, and the length of the radiating arm is related to the required center frequency of the antenna. If the first radiating arm 210 and the second radiating arm 220 are located on opposite sides of the connecting layer 130, the distance of the radiating arm from the antenna center and the length of the radiating arm can be flexibly adjusted during production, thereby changing the center frequency of the antenna and improving the application range of the window module.

[0051] In one embodiment, please combine Figure 1 , Figure 2 and Figure 4 As shown, the first radiating arm 210 and the second radiating arm 220 are both arranged in a strip shape. There are two first radiating arms 210 arranged in parallel with a gap between them. All the first radiating arms 210 are located between the connecting layer 130 and the first glass 110. There are two second radiating arms 220 arranged in parallel with a gap between them. All the second radiating arms 220 are located between the connecting layer 130 and the second glass 120. The extension direction of the second radiating arms 220 is different from the extension direction of the first radiating arms 210.

[0052] like Figure 4 As shown, two first radiating arms 210 are provided and arranged parallel to each other at intervals, with the two first radiating arms 210 forming a pair of opposite sides; combined with Figure 1 and Figure 2 In the illustrated embodiment, the pair of opposite edges is located between the connecting layer 130 and the first glass 110. Because the two first radiating arms 210 are arranged parallel to each other at intervals, they are less likely to come into contact and conduct, thus preventing short circuits and improving the yield rate.

[0053] like Figure 4 As shown, two second radiating arms 220 are provided and arranged parallel to each other at intervals, and the two second radiating arms 220 form another set of opposite sides; combined with Figure 1 and Figure 2In the embodiment shown, the set of opposite sides is located between the connecting layer 130 and the second glass 120. That is, the opposite sides formed by the second radiating arm 220 and the opposite sides formed by the first radiating arm 210 are located on different sides of the connecting layer 130. The two are not easy to make direct contact and conduction, thus solving the short circuit problem caused by contact and conduction and improving the yield. Of course, since the two second radiating arms 220 are arranged in parallel at intervals, the two second radiating arms 220 are also not easy to make contact and conduction and cause short circuit, thereby improving the yield.

[0054] like Figure 4 In the embodiment shown, the extension direction of the first radiating arm 210 is different from that of the second radiating arm 220, so as to achieve antenna polarization in different directions.

[0055] In one embodiment, please refer to Figure 4 The extension direction of the first radiating arm 210 is perpendicular to the extension direction of the second radiating arm 220.

[0056] like Figure 4 In the illustrated embodiment, the two first radiating arms 210 are spaced parallel to each other, and the two second radiating arms 220 are spaced parallel to each other, with the first radiating arms 210 and the second radiating arms 220 being approximately perpendicular, to form an antenna with four radiating arms arranged in a roughly rectangular pattern. In one embodiment, please refer to... Figures 4 to 6 When projecting along the thickness direction of the second glass 120, the first radiating arm 210 forms the first projection body, the second radiating arm 220 forms the second projection body, and the second projection body and the first projection body are alternately arranged to form a ring structure.

[0057] like Figure 4 From the perspective shown, the two first radiating arms 210 are arranged at left and right intervals, and the two second radiating arms 220 are arranged at vertical intervals. The two first radiating arms 210 and the two second radiating arms 220 cooperate to form a ring structure so that the antenna becomes a circularly polarized antenna.

[0058] Optionally, combined Figure 1 and Figure 5 In the embodiment shown, from the perspective of the thickness direction of the second glass 120, the adjacent first radiation arm 210 and second radiation arm 220 are staggered, that is, the adjacent first projection body and second projection body are spaced apart and do not overlap.

[0059] Optionally, with Figure 5 The difference between the embodiments shown is that, in combination with Figure 2 and Figure 6 In the embodiment shown, from the perspective of the thickness direction of the second glass 120, the adjacent first radiation arm 210 and second radiation arm 220 are not staggered, that is, the adjacent first projection body and second projection body are not spaced apart and have overlapping parts.

[0060] Optionally, Figure 1 and Figure 5 The antenna in the illustrated embodiment can be used as a transmitting antenna. Figure 2 and Figure 6 The antenna in the illustrated embodiment can serve as a receiving antenna and is stacked between the first glass 110 and the second glass 120 to improve the level of integration.

[0061] In one embodiment, please refer to Figure 1 and Figure 2 The first glass 110 has a first surface 111 and a second surface 112 opposite to each other, the second glass 120 has a third surface 121 and a fourth surface 122 opposite to each other, and the connecting layer 130 is disposed between the second surface 112 and the third surface 121.

[0062] like Figure 1 and Figure 2 From the shown perspective, the upper surface of the first glass 110 is the first surface 111, which can serve as the outer surface of the window module, and the lower surface of the first glass 110 is the second surface 112. The upper surface of the second glass 120 is the third surface 121, and the lower surface of the second glass 120 is the fourth surface 122, which can serve as the inner surface of the window module. The connecting layer 130 is sandwiched between the first glass 110 and the second glass 120.

[0063] Optionally, the dimensions of the first glass 110 are matched with the dimensions of the second glass 120, and the dimensions of the connecting layer 130 are matched with the dimensions of the first glass 110.

[0064] Please combine Figure 1 , Figure 2 and Figure 3 The first radiating arm 210 includes a first radiating conductor arranged in a strip shape, which is disposed on the second surface 112. The second radiating arm 220 includes a second radiating conductor arranged in a strip shape, which is disposed on the third surface 121.

[0065] Both the first and second radiating conductors are arranged in a strip shape for transmitting and / or receiving signals. When the antenna is used as a transmitting antenna 201, the first and second radiating conductors are primarily used for transmitting signals; when the antenna is used as a receiving antenna 202, the first and second radiating conductors are primarily used for receiving signals.

[0066] The first radiating conductor is disposed on the second surface 112, and the second radiating conductor is disposed on the third surface 121, with the connecting layer 130 separating them to prevent the first radiating conductor and the second radiating conductor from conducting and causing a short circuit.

[0067] In one embodiment, at least two first radiating conductors are provided and are arranged parallel to each other at intervals on the second surface 112. The first radiating arm 210 also includes a first wiring conductor 212, which is electrically connected to the power supply network and connects all the first radiating conductors.

[0068] Similarly, at least two second radiating conductors are provided and are arranged parallel to each other at intervals on the third surface 121. The second radiating arm 220 also includes a second wiring conductor 222, which is electrically connected to the power supply network and connects all the second radiating conductors.

[0069] All the first radiating conductors of the first radiating arm 210 are connected by a first connecting conductor 212 to electrically connect to the power supply network, thereby achieving power supply. The first connecting conductor 212 roughly forms the first power supply port of the first radiating arm 210. The two first radiating arms 210 correspondingly form two first power supply ports.

[0070] All the second radiating conductors of the second radiating arm 220 are connected by the second wiring conductor 222 to electrically connect to the feed network, thereby achieving power feeding. The second wiring conductor 222 roughly forms the second feed port of the second radiating arm 220. The two second radiating arms 220 correspondingly form two second feed ports.

[0071] For example, Figure 5 The antenna shown can be used as a transmitting antenna 201. The first radiating arm 210 includes four first radiating conductors 211a and one first connecting conductor 212a. The four first radiating conductors 211a are arranged in parallel at intervals. The first connecting conductor 212a connects the four first radiating conductors 211a and forms a first feed port for connection to a feed network. The second radiating arm 220 includes four second radiating conductors 221a and one second connecting conductor 222a. The four second radiating conductors 221a are arranged in parallel at intervals. The second connecting conductor 222a connects the four second radiating conductors 221a and forms a second feed port for connection to a feed network.

[0072] For example, Figure 6The antenna shown can be used as a receiving antenna 202. The first radiating arm 210 includes four first radiating conductors 211b and one first connecting conductor 212b. The four first radiating conductors 211b are arranged in parallel with a gap between them. The first connecting conductor 212b connects the four first radiating conductors 211b and forms a first feed port for connection to a feed network. The second radiating arm 220 includes four second radiating conductors 221b and one second connecting conductor 222b. The four second radiating conductors 221b are arranged in parallel with a gap between them. The second connecting conductor 222b connects the four second radiating conductors 221b and forms a second feed port for connection to a feed network.

[0073] Optionally, the spacing between adjacent first radiating conductors of the first radiating arm 210 is 5 mm. The spacing between adjacent second radiating conductors of the second radiating arm 220 is 5 mm.

[0074] In one embodiment, at least one of the first radiating conductor, the first connecting conductor 212, the second radiating conductor, and the second connecting conductor 222 is an enameled wire.

[0075] Optionally, the diameter of the enameled wire is from 0.06 mm to 0.1 mm.

[0076] The enameled wire is sandwiched between the first glass 110 and the second glass 120, making assembly convenient and the structure simple. At the same time, the diameter of the enameled wire is selected between 0.06mm and 0.1mm, which ensures antenna performance while also taking into account the assembly yield of the structure.

[0077] Optionally, the first radiating conductor, the first connecting conductor 212, the second radiating conductor, and the second connecting conductor 222 are all enameled wires.

[0078] Optionally, the first wiring conductor 212 is wound around the outer periphery of all the first radiating conductors, so that the first wiring conductor 212 is directly connected or coupled to all the first radiating conductors. Similarly, the second wiring conductor 222 is wound around the outer periphery of all the second radiating conductors, so that the second wiring conductor 222 is directly connected or coupled to all the second radiating conductors.

[0079] Optionally, the diameter of the enameled wire is 0.08 mm. This diameter can reduce the deviation of the enameled wire during the glass assembly process of the window module, thereby improving the yield rate.

[0080] In one embodiment, please refer to Figure 3 The antenna also includes a first feed conductor 231 and a second feed conductor 232; the first feed conductor 231 is electrically connected to the first wiring conductor 212, the second feed conductor 232 is electrically connected to the second wiring conductor 222, and both the first feed conductor 231 and the second feed conductor 232 are electrically connected to the feed network.

[0081] The first feed conductor 231 is used to electrically connect the first radiating arm 210 to the feed network, and the second feed conductor 232 is used to electrically connect the second radiating arm 220 to the feed network, so as to realize the feed network feeding the first radiating arm 210 and the second radiating arm 220.

[0082] Optionally, the first feed conductor 231 and the first wiring conductor 212 can be directly welded together or coupled together. Similarly, the second feed conductor 232 and the second wiring conductor 222 can also be directly welded together or coupled together, which will not be elaborated further.

[0083] In one embodiment, please refer to Figure 3 and Figure 4 The window module also includes a transmitter 310 and a receiver 320. The transmitter 310 is electrically connected to the transmitting antenna 201, and the receiver 320 is electrically connected to the receiving antenna 202.

[0084] like Figure 3 and Figure 4 In the embodiment shown, two antennas are provided between the first glass 110 and the second glass 120 of the window module. The two antennas are a transmitting antenna 201 and a receiving antenna 202. The transmitter 310 sends a preset signal through the transmitting antenna 201, and the receiver 320 receives the preset signal through the receiving antenna 202, so as to realize the interaction between the window module and the outside world.

[0085] It is understandable that:

[0086] For the transmitting antenna 201, its feeding network can be part of the transmitter 310 or set up independently of the transmitter 310. Similarly, for the receiving antenna 202, its feeding network can be part of the receiver 320 or set up independently of the receiver 320, which will not be elaborated further.

[0087] Optionally, the lengths of the first and second radiating conductors of the transmitting antenna 201 are both 250 mm.

[0088] Optionally, the lengths of the first and second radiating conductors of the receiving antenna 202 are both 200 mm.

[0089] In one embodiment, please refer to Figure 3 A power divider 330 is provided between the transmitter 310 and the transmitting antenna 201. A combiner 340 is provided between the receiver 320 and the receiving antenna 202.

[0090] The signal emitted by transmitter 310 reaches the first radiating arm 210 and the second radiating arm 220 of transmitting antenna 201 through power divider 330. The first radiating arm 210 and the second radiating arm 220 of receiving antenna 202 then pass the received signal through combiner 340 to receiver 320. This configuration achieves optimized signal processing.

[0091] Optionally, such as Figure 3 As shown, the first feed conductor 231 and the second feed conductor 232 of the transmitting antenna 201 are both electrically connected to the power divider 330. The first feed conductor 231 and the second feed conductor 232 of the receiving antenna 202 are both electrically connected to the combiner 340.

[0092] Optionally, such as Figure 3 As shown, the first feed conductor 231 of the transmitting antenna 201 extends to the outside of the edge of the first glass 110 or the outside of the edge of the second glass 120; the second feed conductor 232 of the transmitting antenna 201 extends to the outside of the edge of the first glass 110 or the outside of the edge of the second glass 120, and the power divider 330 is located outside the edge of the first glass 110 or the outside of the edge of the second glass 120.

[0093] Both the first feed conductor 231 and the second feed conductor 232 extend to the edge of the first glass 110 or the second glass 120. On the one hand, the lengths of the first feed conductor 231 and the second feed conductor 232 within the interlayer of the first glass 110 and the second glass 120 can be flexibly arranged. On the other hand, the lengths of the first feed conductor 231 and the second feed conductor 232 outside the interlayer of the first glass 110 and the second glass 120 can be flexibly adjusted so that the phase shift of the circularly polarized antenna can be achieved by adjusting the lengths of the first radiating arm 210 and the second radiating arm 220 of the power divider 330 to the transmitting antenna 201.

[0094] Optionally, an amplifier 350 is also provided between the power divider 330 and the transmitting antenna 201.

[0095] For the transmitting antenna 201, excessively long first feed conductor 231 and second feed conductor 232 will reduce the antenna gain. Therefore, an amplifier 350 is provided to compensate for the resulting reduction in gain and improve the performance of the transmitting antenna 201.

[0096] Specifically, the first feed conductor 231 connects the power divider 330 and the first radiating arm 210, and the second feed conductor 232 connects the power divider 330 and the second radiating arm 220. Both the first feed conductor 231 and the second feed conductor 232 are equipped with amplifiers 350.

[0097] Optionally, such as Figure 3As shown, the transmitter 310, power divider 330, amplifier 350, receiver 320, and combiner 340 are all located outside the sandwich structure of the first glass 110 and the second glass 120, so as to facilitate the splicing of the first glass 110, the second glass 120, the first radiating arm 210, and the second radiating arm 220.

[0098] This embodiment also provides a vehicle including a window module as described in any of the above embodiments.

[0099] The vehicle includes the aforementioned window module, which can be a sunroof module or a front window module, etc. The connecting layer 130 connects the first glass 110 and the second glass 120 into one unit. The first radiating arm 210 and the second radiating arm 220 are sandwiched between the first glass 110 and the second glass 120 and are fed through a power supply network. The transmitting antenna 201 and the receiving antenna 202 enable the window module to transmit and receive signals. During assembly, the first radiating arm 210 is arranged between the first glass 110 and the connecting layer 130, and the second radiating arm 220 is arranged between the second glass 120 and the connecting layer 130. Then, they are assembled. The process is simple, and the first radiating arm 210 and the second radiating arm 220 are located on opposite sides of the connecting layer 130, avoiding short circuits caused by mutual conduction. The yield rate is high, and it is suitable for mass production, meeting actual needs.
