Description

Technical Field

[0001] This application relates to the field of phased array antenna technology, and in particular to a vehicle-mounted phased array antenna and vehicle. Background Technology

[0002] A phased array antenna is an antenna that changes its radiation pattern shape by controlling the feed phase of the radiating elements in the array. Controlling the phase changes the direction of the antenna's maximum radiation value, achieving beam scanning. It achieves precise control of the beam direction and shape by adjusting the signal phase difference between multiple antenna elements.

[0003] Because phased array antennas can complete omnidirectional scanning in microseconds without physical rotation by adjusting the phase difference, they have become core components in radar, communication, satellite and other fields due to their flexibility and efficiency. In recent years, phased array antennas have also been gradually installed and applied to vehicles to achieve vehicle positioning.

[0004] However, all components of current phased array antennas are integrated into the same structure, resulting in a relatively large size. Therefore, when used in vehicles, they can only be mounted on the roof, causing the phased array antenna to protrude from the roof and affecting the smoothness and aesthetics of the vehicle structure. Summary of the Invention

[0005] Therefore, it is necessary to provide a vehicle-mounted phased array antenna and vehicle to address the above-mentioned technical problems, so as to improve the smoothness and aesthetics of the vehicle structure when the phased array antenna is deployed on the vehicle.

[0006] In a first aspect, this application provides a vehicle-mounted phased array antenna, wherein the vehicle-mounted phased array antenna includes an antenna end and a phase controller, the antenna end and the phase controller are separately arranged, the antenna end is disposed on the roof light-transmitting structure of the vehicle, the phase controller is disposed on the vehicle, and the distance between the phase controller and the antenna end is less than a preset distance.

[0007] Based on this embodiment, the vehicle-mounted phased array antenna separates the antenna end and the phase controller. The antenna end is placed on the roof light-transmitting structure of the vehicle, while the phase controller is placed in other locations on the vehicle. This allows the smaller antenna end to be placed together with the roof light-transmitting structure, eliminating the need to place both the antenna end and the phase controller on the roof. This avoids the need for the vehicle-mounted phased array antenna to protrude from the roof, improving the smoothness and aesthetics of the vehicle body structure when the phased array antenna is installed.

[0008] In some embodiments, the vehicle roof light-transmitting structure includes: a first light-transmitting structure portion with a light transmittance greater than a first preset light transmittance threshold, and a second light-transmitting structure portion with a light transmittance less than the first preset light transmittance threshold, with an antenna terminal disposed in the second light-transmitting structure portion.

[0009] Based on this embodiment, the vehicle-mounted phased array antenna, by setting the antenna end in the second light-transmitting structure part with a smaller light transmittance in the light-transmitting structure of the roof, allows the antenna end to be hidden in the part with a smaller light transmittance in the light-transmitting structure of the roof, thus achieving the hidden setting of the antenna end, which helps to improve the smoothness and aesthetics of the vehicle body structure when the phased array antenna is deployed.

[0010] In some embodiments, the second light-transmitting structure portion is located at the edge of the roof light-transmitting structure.

[0011] Based on this embodiment, since the edge of the roof light-transmitting structure is connected to the main body structure of the vehicle, and the main body structure is usually opaque, by setting the second light-transmitting structure with a lower light transmittance at the edge of the roof light-transmitting structure and setting the antenna end in the second light-transmitting structure, it is more conducive to the hidden setting of the antenna end, thereby further improving the smoothness and aesthetics of the vehicle body structure when the phased array antenna is installed.

[0012] In some embodiments, the second light-transmitting structure portion is located at the edge of one side of the roof light-transmitting structure, and the antenna end is disposed at one end of the second light-transmitting structure portion.

[0013] Based on this embodiment, by setting a second light-transmitting structure with lower light transmittance only on one side of the roof light-transmitting structure, and setting the antenna end at one end of the second light-transmitting structure with lower light transmittance, the antenna end can be hidden at one end of the second light-transmitting structure, while other devices can be hidden at the other end of the second light-transmitting structure. This helps to improve the smoothness and aesthetics of the vehicle body structure when a phased array antenna is installed.

[0014] In some embodiments, the vehicle is also provided with a remote communication terminal located at the other end of the second light-transmitting structure portion. The antenna end includes a transmitting array and a receiving array. The transmitting array is located on the side of the antenna end away from the remote communication terminal, and the receiving array is located on the side of the antenna end closer to the remote communication terminal.

[0015] Based on this embodiment, by setting the receiving array at the antenna end on the side of the antenna end closer to the remote communication terminal, it can help increase signal isolation and the signal strength of the received signal.

[0016] In some embodiments, the vehicle roof light-transmitting structure includes: a fixed part and a movable part that moves relative to the fixed part, with the antenna end disposed on the fixed part.

[0017] Based on this embodiment, when the vehicle roof light-transmitting structure includes a fixed part and a movable part that moves relative to the fixed part, by setting the antenna end in the fixed part, the influence of the signal strength of the antenna end receiving the signal during or after the movement of the movable part can be avoided, thereby helping to maintain and ensure the communication performance of the vehicle-mounted phased array antenna.

[0018] In some embodiments, the movable part, after being moved relative to the fixed part, is located on the side adjacent to the vehicle interior space, while the fixed part is located on the side away from the vehicle interior space.

[0019] Based on this embodiment, after the movable part of the roof light-transmitting structure moves relative to the fixed part, the movable part is located on the side adjacent to the vehicle's interior space, while the fixed part is located on the side away from the vehicle's interior space. This allows the fixed part to be located on the side away from the vehicle's interior space after the movable part moves relative to the fixed part, thereby further avoiding the impact of the movable part's movement on the signal strength of the antenna's received signal. This helps to further maintain and ensure the communication performance of the vehicle-mounted phased array antenna.

[0020] In some embodiments, the fixing part includes a third light-transmitting structural portion with a light transmittance greater than a second preset light transmittance threshold and a fourth light-transmitting structural portion with a light transmittance less than the second preset light transmittance threshold. The antenna end is disposed on the fourth light-transmitting structural portion. The first light-transmitting structural portion includes the third light-transmitting structural portion, the second light-transmitting structural portion includes the fourth light-transmitting structural portion, and the first preset light transmittance threshold includes the second preset light transmittance threshold.

[0021] Based on this embodiment, by setting the antenna end in the fourth light-transmitting structure part with lower light transmittance of the fixed part, the antenna end can be hidden in the fixed part with lower light transmittance of the light-transmitting structure of the roof, thus realizing the hidden setting of the antenna end. This is more conducive to the smoothness and aesthetics of the vehicle body structure when a phased array antenna is installed on a vehicle with a movable sunroof.

[0022] In some embodiments, the fourth light-transmitting structural portion is located at the edge of the fixed portion away from the movable portion.

[0023] Based on this embodiment, since the fixed part of the roof light-transmitting structure is far from the edge of the movable part and is connected to the main body structure of the vehicle, and the main body structure is usually opaque, by setting the fourth light-transmitting structure part with lower light transmittance at the edge of the fixed part far from the movable part, and setting the antenna end in the fourth light-transmitting structure part, it is more conducive to the hidden setting of the antenna end, thereby further improving the smoothness and aesthetics of the vehicle body structure when a phased array antenna is installed on a vehicle with a movable sunroof.

[0024] In some embodiments, the antenna end is disposed at one end of the fourth light-transmitting structure portion.

[0025] Based on this embodiment, by setting the antenna end at one end of the fourth light-transmitting structure portion of the fixed part with lower light transmittance, the antenna end can be hidden at one end of the fourth light-transmitting structure portion of the fixed part, while other devices can be hidden at the other end of the fourth light-transmitting structure portion. This further helps to improve the smoothness and aesthetics of the vehicle body structure when a phased array antenna is installed.

[0026] In some embodiments, the vehicle is further provided with a remote communication terminal located at the other end of the fourth light-transmitting structure portion of the fixed part. The antenna end includes a transmitting array and a receiving array. The transmitting array is located on the side of the antenna end away from the remote communication terminal, and the receiving array is located on the side of the antenna end closer to the remote communication terminal.

[0027] In some embodiments, the roof light-transmitting structure includes a first light-transmitting structure and a second light-transmitting structure stacked together. The first light-transmitting structure is disposed on the side of the vehicle away from the vehicle's interior space, and the antenna end is disposed between the first light-transmitting structure and the second light-transmitting structure.

[0028] The vehicle-mounted phased array antenna based on this embodiment includes a roof-mounted light-transmitting structure comprising a first layer of light-transmitting structure and a second layer of light-transmitting structure stacked together, and the antenna end is disposed between the first layer of light-transmitting structure and the second layer of light-transmitting structure. The first layer of light-transmitting structure and the second layer of light-transmitting structure of the roof-mounted light-transmitting structure are usually sealed, which helps to improve the sealing performance of the antenna end. This can reduce the problems of rainwater erosion and dust accumulation caused by long-term exposure of the antenna end to air to a certain extent, and help to improve the stability of signal reception at the antenna end.

[0029] In some embodiments, the antenna end is disposed on the side of the roof light-transmitting structure near the vehicle interior space.

[0030] Based on this embodiment, by setting the antenna end on the side of the roof light-transmitting structure closer to the vehicle interior space, it is more conducive to the installation and setting of the antenna end, and facilitates the installation of the antenna end relative to the roof transparent structure.

[0031] In some embodiments, the antenna end includes a first antenna element layer and a phase modulation chip, which are disposed on the side of the roof light-transmitting structure close to the vehicle interior space.

[0032] Based on this embodiment, by setting both the first antenna unit layer and the phase modulation chip on the side of the roof light-transmitting structure closer to the vehicle's interior space, it is more conducive to the installation of the first antenna unit layer and the phase modulation chip. This facilitates the installation of the antenna end with the roof transparent structure. Furthermore, by attaching the first antenna unit layer and the phase modulation chip together, the structural design requirements for the phase modulation chip can be reduced. For example, it is not necessary to set up structures such as special dielectric materials, which further reduces the thickness of the antenna end structure and makes the setting and installation of the antenna end more convenient.

[0033] In some embodiments, the antenna end further includes a second antenna unit layer, which is disposed on the side of the first antenna unit layer away from the vehicle interior space.

[0034] Based on this embodiment, by further providing a second antenna unit layer on the side of the first antenna unit layer away from the vehicle interior space, the signal loss caused by the light-transmitting structure of the roof blocking the signal of the first antenna unit layer can be compensated, which helps to ensure the communication performance of the antenna end.

[0035] In some embodiments, the roof light-transmitting structure includes a first light-transmitting structure and a second light-transmitting structure stacked together. The first light-transmitting structure is disposed on the side of the vehicle away from the vehicle's interior space. The antenna end also includes a second antenna unit layer, which is disposed between the first light-transmitting structure and the second light-transmitting structure.

[0036] Based on this embodiment, by setting the roof light-transmitting structure to include a first light-transmitting structure and a second light-transmitting structure stacked together, and placing the second antenna unit layer between the first light-transmitting structure and the second light-transmitting structure, the problems of rainwater erosion and dust accumulation caused by the long-term exposure of the second antenna unit layer to the air can be reduced, which helps to improve the stability and strength of the antenna signal reception.

[0037] In some embodiments, the second antenna unit layer is disposed on the side of the first light-transmitting structure adjacent to the second light-transmitting structure.

[0038] Based on this embodiment, by setting the second antenna unit layer at the antenna end on the side adjacent to the first light-transmitting structure and the second light-transmitting structure, the problems of rainwater erosion and dust accumulation caused by the long-term exposure of the second antenna unit layer to the air can be reduced. At the same time, the second antenna unit layer is located closer to the external space of the vehicle, which can help to further improve the stability and strength of the transmitted and received signals at the antenna end, and help to further ensure the communication performance of the antenna end.

[0039] In some embodiments, the second antenna unit layer is printed on the side of the first light-transmitting structure adjacent to the second light-transmitting structure.

[0040] Based on this embodiment, by printing the second antenna unit layer on the side adjacent to the second light-transmitting structure of the first light-transmitting structure, a planar structure design for the second antenna unit layer can be achieved, which can significantly reduce the overall volume and is more conducive to improving the smoothness and aesthetics of the vehicle body structure when a phased array antenna is installed.

[0041] In some embodiments, the operating frequency of the second antenna element layer is the same as the operating frequency of the first antenna element layer.

[0042] Based on this embodiment, by setting the communication frequency of the second antenna unit layer to be the same as that of the first antenna unit layer, it is more conducive to the overlap of the peaks and troughs of the signal generated by the first antenna unit layer with the peaks and troughs of the signal generated by the second antenna unit layer. This is more conducive to compensating for the signal energy loss caused by the light-transmitting structure of the roof blocking the signal of the first antenna unit layer, and helps to ensure and improve the communication performance of the antenna end.

[0043] In some embodiments, the second antenna element layer and the first antenna element layer are connected via a feeder.

[0044] By connecting the second antenna unit layer and the first antenna unit layer through a feed line, the installation complexity of the second antenna unit layer is reduced, and the installation convenience of various components at the antenna end, such as the second antenna unit layer, is improved.

[0045] In some embodiments, the antenna end is integrated with the roof light-transmitting structure.

[0046] Based on this embodiment, by integrating the antenna end with the roof light-transmitting structure, it helps to further reduce installation complexity, and also helps to reduce external components, which is more conducive to improving the smoothness and aesthetics of the vehicle body structure when a phased array antenna is installed.

[0047] In some embodiments, the phase controller is disposed on the main body structure of the vehicle body adjacent to the roof light-transmitting structure.

[0048] Based on this embodiment, by setting the phase controller, which is separately set from the antenna end, on the main body structure of the vehicle body adjacent to the roof light-transmitting structure, it is possible to better control the distance between the phase controller and the antenna end while setting the phase controller separately from the antenna end. Furthermore, setting the phase controller on the main body structure of the vehicle body also helps to improve the convenience of phase controller installation.

[0049] In some embodiments, the distance between the phase controller and the roof light-transmitting structure is within a preset range, and the upper limit of the preset range is less than the preset distance.

[0050] Based on this embodiment, by setting the phase controller at a position within a preset range from the roof light-transmitting structure, and since the antenna is set at the roof light-transmitting structure, the distance between the phase controller and the antenna can be controlled based on the control of the distance from the roof light-transmitting structure. This helps to make the phase controller position setting more convenient and efficient, and can reduce the impact of vibrations during vehicle operation on devices located below the roof light-transmitting structure.

[0051] In some embodiments, the phase controller is located on the adjacent body structure below the location of the roof light-transmitting structure where the antenna is located.

[0052] Based on this embodiment, the vehicle-mounted phased array antenna, by setting the phase controller on the main body structure adjacent to the roof light-transmitting structure where the antenna end is located, allows the phase controller to be placed as close as possible to the antenna end, which helps to improve the signal transmission performance between the antenna end and the phase controller, thereby improving the communication performance of the vehicle-mounted phased array antenna.

[0053] In some embodiments, the phase controller is disposed on the vehicle body structure adjacent to a first side of the first light-transmitting structure portion, wherein the first side of the first light-transmitting structure portion is the side away from the second light-transmitting structure portion.

[0054] Based on this embodiment, the vehicle-mounted phased array antenna, by placing the phase controller adjacent to the first light-transmitting structural portion with relatively high light transmittance in the vehicle's light-transmitting structure, and adjacent to the first side of the first light-transmitting structural portion on the main body structure of the vehicle body, while the first side of the first light-transmitting structural portion is the side away from the second light-transmitting structural portion with relatively low light transmittance, it is not necessary to restrict the phase controller to a position adjacent to the antenna end. The phase controller can be set based on the vehicle body volume, which helps to further improve the convenience of determining the phase controller's setting position.

[0055] In some embodiments, the preset range includes 20-35 mm.

[0056] Based on this embodiment, the vehicle-mounted phased array antenna, by setting the phased array device within a distance of 20-35 mm from the roof light-transmitting structure, can maintain the communication performance between the phased array device and the antenna end, while allowing the phased array device to be as close as possible to the main body structure of the vehicle body. This is more conducive to the stealth setting of the phased array device, and also helps to improve the smoothness and aesthetics of the vehicle body structure when the phased array antenna is installed. In addition, it can reduce the impact of vibrations during vehicle operation on the devices set under the roof light-transmitting structure.

[0057] Secondly, this application also provides a vehicle, wherein the vehicle includes a main body structure and a roof light-transmitting structure, and the vehicle is further provided with an on-board phased array antenna as described in any of the embodiments above.

[0058] Based on this embodiment, the vehicle features a separate onboard phased array antenna with the antenna end and phase controller separately mounted on the vehicle. The antenna end is located on the roof light-transmitting structure, while the phase controller is located in other parts of the vehicle. This allows the smaller antenna end to be mounted together with the roof light-transmitting structure, eliminating the need to mount both the antenna end and the phase controller on the roof. This avoids the need for the phased array antenna to protrude from the roof and improves the smoothness and aesthetics of the vehicle body structure when the phased array antenna is mounted.

[0059] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application.

[0077] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0078] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0079] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0080] In the description of the embodiments of this application, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0081] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0082] In the description of the embodiments in this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0083] In the description of the embodiments of this application, the term "multiple" refers to two or more (including two), similarly, "multiple sets" refers to two or more (including two sets), and "multiple pieces" refers to two or more (including two pieces).

[0084] Phased array antennas, by adjusting the phase difference, can complete omnidirectional scanning of the beam in microseconds without physical rotation, making them a core component in radar, communications, and satellite fields due to their flexibility and efficiency. However, current phased array antennas integrate all components into a single structure, resulting in a relatively large size. Consequently, when applied to vehicles, phased array antennas can only be mounted on the roof, causing them to protrude and affecting the vehicle's structural streamline and aesthetics.

[0085] Research has shown that it is advisable to separate the antenna end (which transmits and receives signals and controls phase modulation) and the phase controller (which performs phase calculation and control) of the phased array antenna. The positions of the antenna end and the phase controller on the vehicle can be determined based on the characteristics of the vehicle. This approach aims to achieve the communication function of the phased array antenna and meet the vehicle's communication needs while avoiding the need for the phased array antenna to protrude from the roof. This would improve the smoothness and aesthetics of the vehicle's structure after the phased array antenna is installed.

[0086] Accordingly, this application provides a vehicle-mounted phased array antenna, wherein the vehicle-mounted phased array antenna includes an antenna end and a phase controller, the antenna end and the phase controller are separately arranged, the antenna end is arranged on the light-transmitting structure of the vehicle roof, the phase controller is arranged on the vehicle, and the distance between the phase controller and the antenna end is less than a preset distance.

[0087] The antenna end is the part of the vehicle-mounted phased array antenna used for transmitting and receiving signals, as well as for controlling the phase of the antenna. It can perform phase adjustment of the antenna so that the antenna radiates in a specified direction for beam scanning and control.

[0088] The phase controller is the part of a vehicle-mounted phased array antenna used to calculate the specific phase modulation phase in order to perform phase modulation control, and can communicate with other devices that need to use positioning information.

[0089] Separate antenna and phase controller configuration refers to configuring the antenna and phase controller as two independent devices. This allows them to be placed in different locations to meet the needs of various scenarios. By separating the antenna and phase controller, they can be deployed as needed.

[0090] A roof-mounted light-transmitting structure is a structure located at the top of a vehicle that allows light to pass through. (See reference...) Figure 1 As shown, the roof light-transmitting structure 10 is located on top of the vehicle 1000. In a specific example, the roof light-transmitting structure can be a sunroof on the roof of the vehicle.

[0091] The specific location of the sunroof on the vehicle roof and the proportion of the roof area it occupies are not limited. For example, the roof light-transmitting structure 10 can be located in the area of ​​the roof near the windshield 401, such as... Figure 2 As shown in (1), at this time, the area of ​​the roof light-transmitting structure 10 is relatively small compared to the overall area of ​​the roof. In a specific example, the area of ​​the roof light-transmitting structure 10 is relatively small compared to the area between the front windshield 401 and the rear windshield 402 of the roof. This ratio can be less than a certain preset ratio (which can be referred to as the first preset ratio in this application embodiment).

[0092] For example, the roof light-transmitting structure 10 can be installed in most of the area between the front windshield 401 and the rear windshield 402 of the roof, such as... Figure 2 As shown in (2), at this time, the ratio of the area of ​​the roof light-transmitting structure 10 to the area between the front windshield 401 and the rear windshield 402 of the roof can be greater than a certain preset ratio (which can be referred to as the second preset ratio in this embodiment). The first preset ratio and the second preset ratio can be the same or different. The specific data of the first preset ratio and the second preset ratio can be set based on the vehicle model structure, etc.

[0093] For example, the roof light-transmitting structure 10 can be installed in the entire area between the front windshield 401 and the rear windshield 402 on the roof, thus creating a panoramic sunroof effect when viewed from outside the vehicle. Figure 2 (3) As shown. It is understood that, in order to present the visual effect of a panoramic sunroof, corresponding connecting structures and / or supporting structures can be provided at the positions where the front windshield 401 is connected to the roof light-transmitting structure 10 and the rear windshield 402 is connected to the roof light-transmitting structure 10. This application embodiment does not show this in detail.

[0094] It is understood that in other embodiments, the specific location, shape, and arrangement of the roof light-transmitting structure 10 on the roof can also be configured differently. The specific material of the roof light-transmitting structure 10 is not limited; for example, in some examples, the roof light-transmitting structure can be made of glass or other materials, but it is not limited to these.

[0095] refer to Figure 1 As shown, the antenna end 201 of the vehicle-mounted phased array antenna is disposed on the roof light-transmitting structure 10 of the vehicle 1000, and the phased array antenna ( Figure 1 , 2 (Not shown in the image) is positioned at a distance less than a preset distance between the vehicle 1000 and the antenna terminal 201, so that the antenna terminal 201 and the phase controller can communicate with each other while satisfying the separate setup.

[0096] The specific value of the preset distance can be set according to specific needs, as long as it can meet the communication requirements between the antenna 201 and the phase controller. For example, the preset distance in some examples can be set to 1.5 meters (m), but it is not limited to this.

[0097] Based on this embodiment, the vehicle-mounted phased array antenna separates the antenna end and the phase controller. The antenna end is placed on the roof light-transmitting structure of the vehicle, while the phase controller is placed in other locations on the vehicle. This allows the smaller antenna end to be placed together with the roof light-transmitting structure, eliminating the need to place both the antenna end and the phase controller on the roof. This avoids the need for the vehicle-mounted phased array antenna to protrude from the roof, improving the smoothness and aesthetics of the vehicle body structure when the phased array antenna is installed.

[0098] The specific structure of the roof light-transmitting structure is not limited. In some embodiments, the roof light-transmitting structure includes: a first light-transmitting structure portion with a light transmittance greater than a first preset light transmittance threshold, and a second light-transmitting structure portion with a light transmittance less than the first preset light transmittance threshold, with the antenna end disposed in the second light-transmitting structure portion.

[0099] Light transmittance is a parameter that represents the ability of light to pass through a medium. It can be calculated by calculating the percentage of light flux transmitted through the medium to the incident light flux. The medium is usually a transparent or translucent medium. In the relevant embodiments of this application, the medium of the transparent roof structure may include glass, but is not limited thereto.

[0100] The specific value of the first preset light transmittance threshold is not limited, as long as it can distinguish between the first and second light transmittance structural portions with different light transmittance. In some specific examples, the first preset light transmittance threshold may include a first threshold and a second threshold, with the first threshold being greater than the second threshold. The light transmittance of the first light transmittance structural portion is greater than the first threshold, so that more light can pass through the first light transmittance structural portion to reach the vehicle interior space. The light transmittance of the second light transmittance structural portion is less than the second threshold, so that the light passing through the second light transmittance structural portion to reach the vehicle interior space is minimized, or even eliminated.

[0101] Since the light transmittance of the second light-transmitting structure is lower than that of the first light-transmitting structure, by placing the antenna end in the second light-transmitting structure with lower light transmittance, the influence of the antenna end on the light reaching the vehicle interior space can be reduced, and the visibility of the antenna end can be minimized, thus achieving a hidden antenna end.

[0102] In this design, the first and second light-transmitting structural portions can be integrally formed. For example, during the construction of a roof light-transmitting structure, the light transmittance of the integrally formed first and second light-transmitting structural portions can be achieved by adjusting the medium and its arrangement. In other examples, after obtaining a roof light-transmitting structure with the same light transmittance through integral forming, a second light-transmitting structural portion with even lower light transmittance can be obtained by superimposing a film with low light transmittance, such as by pasting a film with low light transmittance, on the area of ​​the second light-transmitting structural portion. It is understood that roof light-transmitting structures with different light transmittances can also be obtained through other methods, and this application does not impose specific limitations.

[0103] Based on this embodiment, the vehicle-mounted phased array antenna, by setting the antenna end in the second light-transmitting structure part with a smaller light transmittance in the light-transmitting structure of the roof, allows the antenna end to be hidden in the part with a smaller light transmittance in the light-transmitting structure of the roof, thus achieving the hidden setting of the antenna end, which helps to improve the smoothness and aesthetics of the vehicle body structure when the phased array antenna is deployed.

[0104] The specific location of the second light-transmitting structure within the roof light-transmitting structure is not limited. In some examples, the second light-transmitting structure is located at the edge of the roof light-transmitting structure.

[0105] The edge of the roof light-transmitting structure refers to the peripheral part of the roof light-transmitting structure. By setting the second light-transmitting structure with a lower light transmittance at the edge of the roof light-transmitting structure, and setting the first light-transmitting structure with a higher light transmittance at the center of the roof light-transmitting structure, the light transmission of the center of the roof light-transmitting structure is not affected, so that the light from outside the vehicle can be projected into the interior space of the vehicle through the center of the roof light-transmitting structure as much as possible.

[0106] The edge of the roof light-transmitting structure is where it connects with other parts of the vehicle, such as the main body structure. Therefore, by placing the second light-transmitting structure at the edge of the roof light-transmitting structure and placing the antenna end at the second light-transmitting structure, it is more advantageous to hide the antenna end within the roof light-transmitting structure.

[0107] Based on this embodiment, since the edge of the roof light-transmitting structure is connected to the main body structure of the vehicle, and the main body structure is usually opaque, by setting the second light-transmitting structure with a lower light transmittance at the edge of the roof light-transmitting structure and setting the antenna end in the second light-transmitting structure, it is more conducive to the hidden setting of the antenna end, thereby further improving the smoothness and aesthetics of the vehicle body structure when the phased array antenna is installed.

[0108] Alternatively, a second light-transmitting structure with lower light transmittance can be provided on each side edge of the roof light-transmitting structure, or the second light-transmitting structure can be provided only on one side edge of the roof light-transmitting structure. In the relevant embodiments of this application, the second light-transmitting structure can be located on one side edge of the roof light-transmitting structure, in which case the first light-transmitting structure can be located on the other side of the roof light-transmitting structure.

[0109] In related embodiments, the second light-transmitting structure portion can be located at the edge of any side of the roof light-transmitting structure. In this embodiment, reference is made to... Figure 3 As shown, the second light-transmitting structure portion 112 can be disposed on the side of the roof light-transmitting structure near the rear of the vehicle. At this time, the first light-transmitting structure portion 111 is located on the side of the roof light-transmitting structure near the front of the vehicle.

[0110] The second light-transmitting structure portion 112, which is provided on one side edge of the roof light-transmitting structure 10, may have an antenna end located at one end of the second light-transmitting structure portion 112.

[0111] Based on this embodiment, by setting a second light-transmitting structure with lower light transmittance only on one side of the roof light-transmitting structure, and setting the antenna end at one end of the second light-transmitting structure with lower light transmittance, the antenna end can be hidden at one end of the second light-transmitting structure, while other devices can be hidden at the other end of the second light-transmitting structure. This helps to improve the smoothness and aesthetics of the vehicle body structure when a phased array antenna is installed.

[0112] The device disposed at the other end of the second light-transmitting structure portion 112 is not limited. In some embodiments of this application, reference is made to... Figure 4 As shown, the antenna end 201 is disposed at one end of the second light-transmitting structure portion 112, and the vehicle 1000 is also provided with a TBOX (Telematics Box, a remote communication terminal, referred to as TBOX in the following embodiments) 30 located at the other end of the second light-transmitting structure portion 112.

[0113] A TBOX is a communication module installed in a vehicle, whose core function is to establish a connection between the vehicle and an external network. The vehicle-mounted phased array antenna provided in this embodiment is a communication device for the vehicle to communicate with and locate external systems. Therefore, by placing the antenna end at one end of the second light-transmitting structure portion 112 and the TBOX at the other end of the second light-transmitting structure portion 112, both the antenna end and the TBOX can be hidden, while also achieving close proximity between them, which helps to further improve the vehicle's communication performance.

[0114] The antenna end 201 may include a transmitting array and a receiving array. In some examples, the transmitting array is located on the side of the antenna end 201 away from the TBOX 30, and the receiving array is located on the side of the antenna end 201 closer to the TBOX 30, such as... Figure 5 As shown, the transmitting array 2012 is located on the right side of the antenna end 201, and the receiving array 2011 is located on the left side of the antenna end 201, which is closer to the TBOX.

[0115] The transmitting array is the antenna array in a phased array antenna used to directionally transmit electromagnetic waves to a target area. The receiving array is the antenna array in a phased array antenna used to receive electromagnetic wave signals and convert them into electrical signals for subsequent processing. By placing the receiving array closer to the TBOX, the signal strength received by the receiving array can be increased, and the isolation between the transmitted and received signals can be increased accordingly.

[0116] Based on this embodiment, by setting the receiving array at the antenna end to the side of the antenna end closer to the TBOX, it can help increase signal isolation and the signal strength of the received signal.

[0117] Other structural forms of the roof-mounted light-transmitting structure are not limited. For example, the roof-mounted light-transmitting structure can be a single, integrally formed structure or it can consist of multiple different components. Taking the roof-mounted light-transmitting structure that achieves light transmission through glass as an example, the roof-mounted light-transmitting structure can include a single, integrally formed piece of glass or it can be composed of multiple pieces of glass spliced ​​together. In some specific examples of this application, the vehicle's roof-mounted light-transmitting structure includes: a fixed part and a movable part that moves relative to the fixed part, with the antenna end disposed on the fixed part.

[0118] The fixed part is the stationary, immovable portion of the roof light-transmitting structure, while the movable part is the portion that can move or shift relative to the fixed part. By fixing or moving the movable part relative to the fixed part, airflow between the vehicle's interior and exterior spaces can be controlled as needed, allowing for either flow between the movable and external spaces.

[0119] The specific area, shape, and relative position of the fixed and movable parts in the roof light-transmitting structure are not limited. In some examples, the fixed part may be located on the side of the roof light-transmitting structure closer to the rear of the vehicle, while the movable part may be located on the side of the roof light-transmitting structure closer to the front of the vehicle, such as... Figure 6 As shown, the roof light-transmitting structure includes a fixed part 121 and a movable part 122, the movable part 122 being movable relative to the fixed part 121.

[0120] The antenna end is located in the fixed part, so that the antenna end will not move with the moving part during the movement of the moving part, which helps to improve the stability of the communication performance of the antenna end.

[0121] In the case where the transparent roof structure includes a first light-transmitting structure part with high light transmittance and a second light-transmitting structure part with low light transmittance, the second light-transmitting structure part can be set on the side of the fixing part near the rear of the vehicle, and the antenna end can be set at one end of the second light-transmitting structure part. The TBOX can be set at the other end of the second light-transmitting structure part, so as to improve the stability of the communication performance of the antenna end while realizing the hidden setting of the antenna end.

[0122] Based on this embodiment, when the vehicle roof light-transmitting structure includes a fixed part and a movable part that moves relative to the fixed part, by setting the antenna end in the fixed part, the influence of the signal strength of the antenna end receiving the signal during or after the movement of the movable part can be avoided, thereby helping to maintain and ensure the communication performance of the vehicle-mounted phased array antenna.

[0123] The relative positions of the movable part and the fixed part before and after movement are not limited. In some examples, where the air inside and outside the vehicle does not circulate through the area where the roof light-transmitting structure is located, the movable part 122 and the fixed part 121 may be on the same plane, or there may be no height difference or no obvious height difference at the junction of the movable part 122 and the fixed part 121, such as... Figure 7 As shown in (1). After the movable part moves relative to the fixed part, the movable part 122 moves relative to the fixed part 121 to a position adjacent to the vehicle interior space, while the fixed part 121 is located on a side away from the vehicle interior space. Figure 7 As shown in (2).

[0124] Combination Figure 7 As shown, after the movable part 122 moves relative to the fixed part 121, the movable part 122 is located on the side adjacent to the vehicle interior space, and the fixed part 121 is located on the side away from the vehicle interior space. That is, the movable part 122 is located below the fixed part 121. At this time, the distance between the antenna end 201 provided on the fixed part 121 and the vehicle exterior space does not change. Therefore, the communication performance of the antenna end will not be affected by the movement of the movable part before and after the movement of the movable part.

[0125] Based on this embodiment, after the movable part of the roof light-transmitting structure moves relative to the fixed part, the movable part is located on the side adjacent to the vehicle's interior space, while the fixed part is located on the side away from the vehicle's interior space. This allows the fixed part to be located on the side away from the vehicle's interior space after the movable part moves relative to the fixed part, thereby further avoiding the impact of the movable part's movement on the signal strength of the antenna's received signal. This helps to further maintain and ensure the communication performance of the vehicle-mounted phased array antenna.

[0126] Continue to refer to Figure 6As shown, the fixing part 121 may include a third light-transmitting structure part 113 with a light transmittance greater than the second preset light transmittance threshold, and a fourth light-transmitting structure part 114 with a light transmittance less than the second preset light transmittance threshold. The antenna end 201 is disposed on the fourth light-transmitting structure part 114. The first light-transmitting structure part 111 includes the third light-transmitting structure part 113, the second light-transmitting structure part 112 includes the fourth light-transmitting structure part 114, and the first preset light transmittance threshold includes the second preset light transmittance threshold.

[0127] Based on this embodiment, by setting the antenna end in the fourth light-transmitting structure part with lower light transmittance of the fixed part, the antenna end can be hidden in the fixed part with lower light transmittance of the light-transmitting structure of the roof, thus realizing the hidden setting of the antenna end. This is more conducive to the smoothness and aesthetics of the vehicle body structure when a phased array antenna is installed on a vehicle with a movable sunroof.

[0128] The location of the fourth light-transmitting structure portion 114 in the fixed portion is not limited. In some specific examples, the fourth light-transmitting structure portion 114 is located at the edge of the fixed portion away from the movable portion.

[0129] Based on this embodiment, since the fixed part of the roof light-transmitting structure is far from the edge of the movable part and is connected to the main body structure of the vehicle, and the main body structure is usually opaque, by setting the fourth light-transmitting structure part with lower light transmittance at the edge of the fixed part far from the movable part, and setting the antenna end in the fourth light-transmitting structure part, it is more conducive to the hidden setting of the antenna end, thereby further improving the smoothness and aesthetics of the vehicle body structure when a phased array antenna is installed on a vehicle with a movable sunroof.

[0130] The position of the antenna end at the edge of the fourth light-transmitting structure is not limited. In some specific examples, the antenna end is located at one end of the fourth light-transmitting structure.

[0131] Based on this embodiment, by setting the antenna end at one end of the fourth light-transmitting structure portion of the fixed part with lower light transmittance, the antenna end can be hidden at one end of the fourth light-transmitting structure portion of the fixed part, while other devices can be hidden at the other end of the fourth light-transmitting structure portion. This further helps to improve the smoothness and aesthetics of the vehicle body structure when a phased array antenna is installed.

[0132] In some embodiments, the vehicle is further provided with a TBOX located at the other end of the fourth light-transmitting structure portion of the fixed part. The antenna end includes a transmitting array and a receiving array. The transmitting array is located on the side of the antenna end away from the TBOX, and the receiving array is located on the side of the antenna end close to the TBOX.

[0133] Among them, continue to refer to Figure 6As shown, the first light-transmitting structure may further include a movable part 122. The light transmittance of the movable part 122 is higher than a third preset light transmittance threshold.

[0134] The second preset light transmittance threshold and the third preset light transmittance threshold can be the same or different.

[0135] When the second preset light transmission threshold and the third preset light transmission threshold are the same, the light transmittance of the movable part 122 and the light transmittance of the third light transmission structure part 113 of the fixed part 121 can be set to be the same to achieve a consistent light transmission effect.

[0136] In other examples, when the second preset light transmittance threshold and the third preset light transmittance threshold are the same or different, the light transmittance of the movable part 122 and the light transmittance of the third light transmittance structure portion 113 of the fixed part 121 can also be set to be different, as long as the light transmittance of the movable part 122 and the light transmittance of the third light transmittance structure portion 113 are both higher than the light transmittance of the fourth light transmittance structure portion 114 of the fixed part 121, so as to achieve differentiated and personalized light transmittance settings and effects.

[0137] As described above, the first light-transmitting structural portion with a light transmittance greater than the first preset light transmittance threshold may include the third light-transmitting structural portion 113, which includes the aforementioned movable portion 122 and the fixed portion. The second light-transmitting structural portion 112 with a light transmittance less than the first preset light transmittance threshold includes the fourth light-transmitting structural portion 114. In this case, the first preset light transmittance threshold includes the aforementioned second preset light transmittance threshold and the third preset light transmittance threshold.

[0138] It is understood that, in the relevant embodiments of this application, the first light-transmitting structural portion, the third light-transmitting structural portion, or the movable portion of the roof light-transmitting structure may include multiple different portions, each portion may be arranged in a certain pattern, and the light transmittance of each portion may be set to be different, thereby achieving personalized and differentiated light transmission effects. In other embodiments, the light transmittance of the first light-transmitting structural portion, the third light-transmitting structural portion, and the movable portion of the roof light-transmitting structure may all be set to the same value, thereby achieving a consistent and overall light transmission effect.

[0139] The location of the antenna on the roof light-transmitting structure can be set according to technical requirements. The following examples illustrate this.

[0140] In some examples, reference Figure 8 As shown, the roof light-transmitting structure includes a first light-transmitting structure 131 and a second light-transmitting structure 132 stacked together. The first light-transmitting structure 131 is located on the side of the vehicle away from the interior space of the vehicle, and the antenna end 201 is located between the first light-transmitting structure 131 and the second light-transmitting structure 132.

[0141] The vehicle-mounted phased array antenna based on this embodiment includes a roof-mounted light-transmitting structure comprising a first layer of light-transmitting structure and a second layer of light-transmitting structure stacked together, and the antenna end is disposed between the first layer of light-transmitting structure and the second layer of light-transmitting structure. The first layer of light-transmitting structure and the second layer of light-transmitting structure of the roof-mounted light-transmitting structure are usually sealed, which helps to improve the sealing performance of the antenna end. This can reduce the problems of rainwater erosion and dust accumulation caused by long-term exposure of the antenna end to air to a certain extent, and help to improve the stability of signal reception at the antenna end.

[0142] In some examples, reference Figure 1 As shown, the antenna end 201 is disposed on the side of the roof light-transmitting structure 10 close to the vehicle interior space. That is, the antenna end 201 can be disposed below the roof light-transmitting structure 10, adjacent to the vehicle interior space.

[0143] Based on this embodiment, by setting the antenna end on the side of the roof light-transmitting structure closer to the vehicle interior space, it is more conducive to the installation and setting of the antenna end, and facilitates the installation of the antenna end relative to the roof transparent structure.

[0144] The antenna end 201 may include a first antenna unit layer and a phase modulation chip. In a specific example, the first antenna unit layer and the phase modulation chip may be disposed on the side of the roof light-transmitting structure 10 close to the vehicle interior space.

[0145] The antenna element layer is the unit used to transmit and receive signals in a vehicle-mounted phased array antenna. By controlling the phase and amplitude of the transmitted and received signals in the antenna element layer, an adjustable beam direction and shape can be formed.

[0146] A phase modulation chip is a chip used to adjust the phase and amplitude of an antenna element layer. In this embodiment, the antenna element layer adjacent to the phase modulation chip is referred to as the first antenna element layer.

[0147] In some embodiments, the antenna element layer may include an antenna element layer of the transmitting array and an antenna element layer of the receiving array. The antenna element layer of the transmitting array and the antenna element layer of the receiving array may be set separately. When the transmitting array and the receiving array share the same aperture by stacking, the antenna element layer of the transmitting array and the antenna element layer of the receiving array may also be coaxially distributed.

[0148] Based on this embodiment, by setting both the first antenna unit layer and the phase modulation chip on the side of the roof light-transmitting structure closer to the vehicle's interior space, it is more conducive to the installation of the first antenna unit layer and the phase modulation chip. This facilitates the installation of the antenna end with the roof transparent structure. Furthermore, by attaching the first antenna unit layer and the phase modulation chip together, the structural design requirements for the phase modulation chip can be reduced. For example, it is not necessary to set up structures such as special dielectric materials, which further reduces the thickness of the antenna end structure and makes the setting and installation of the antenna end more convenient.

[0149] In some examples, the antenna end also includes a second antenna element layer, which is located on the side of the first antenna element layer away from the vehicle interior space.

[0150] In this embodiment, the antenna element layer that is different from the first antenna element layer and is far from the interior space of the vehicle is referred to as the second antenna element layer. That is, when viewed from the side of the vehicle, the second antenna element layer is located above the first antenna element layer.

[0151] With both a first antenna element layer and a second antenna element layer configured, the antenna elements of the first antenna element layer can transmit and receive signals at a certain operating frequency, and the second antenna element layer can also transmit and receive signals at a certain operating frequency. This allows the configuration of the first and second antenna element layers to adapt to different communication scenarios, thereby improving signal coverage and anti-interference capabilities.

[0152] Based on this embodiment, by providing a second antenna unit layer on the side of the first antenna unit layer away from the vehicle interior space, the signal loss caused by the light-transmitting structure of the roof blocking the signal of the first antenna unit layer can be compensated, which helps to ensure the communication performance of the antenna end.

[0153] The specific location of the second antenna element layer can be set according to actual technical needs. In the relevant embodiments of this application, reference is made to... Figure 9 As shown, the roof light-transmitting structure includes a first light-transmitting structure 131 and a second light-transmitting structure 132 stacked together. The first light-transmitting structure 131 is located on the side of the vehicle away from the vehicle's interior space, and the second antenna unit layer 212 is located between the first light-transmitting structure 131 and the second light-transmitting structure 132. Specifically, the first antenna unit layer 211 is located on the side of the second light-transmitting structure 132 adjacent to the vehicle's interior space, that is, on the side below the second light-transmitting structure 132.

[0154] Based on this embodiment, by setting the roof light-transmitting structure to include a first light-transmitting structure and a second light-transmitting structure stacked together, and placing the second antenna unit layer between the first light-transmitting structure and the second light-transmitting structure, the problems of rainwater erosion and dust accumulation caused by the long-term exposure of the second antenna unit layer to the air can be reduced, which helps to improve the stability and strength of the antenna signal reception.

[0155] The specific location of the second antenna unit layer 212 between the first light-transmitting structure 131 and the second light-transmitting structure 132 is not limited. In the relevant embodiments of this application, the second antenna unit layer 212 is disposed on the side of the first light-transmitting structure 131 adjacent to the second light-transmitting structure 132. Figure 9 As shown, the second antenna unit layer 212 is disposed on one side below the first light-transmitting structure 131.

[0156] Based on this embodiment, by setting the second antenna unit layer at the antenna end on the side adjacent to the first light-transmitting structure and the second light-transmitting structure, the problems of rainwater erosion and dust accumulation caused by the long-term exposure of the second antenna unit layer to the air can be reduced. At the same time, the second antenna unit layer is located closer to the external space of the vehicle, which can help to further improve the stability and strength of the transmitted and received signals at the antenna end, and help to further ensure the communication performance of the antenna end.

[0157] The second antenna element layer can be disposed below the first light-transmitting structure in various possible ways. In related embodiments, the second antenna element layer is printed on the side of the first light-transmitting structure adjacent to the second light-transmitting structure, for example, by silver plating printing.

[0158] By printing the second antenna unit layer onto the underside of the first light-transmitting structure, it is small in size, low in cost, and simple in manufacturing process. This allows for miniaturized implementation of the second antenna unit layer and also makes it easier to hide the second antenna unit layer in the first light-transmitting structure.

[0159] It is understandable that corresponding first and second light-transmitting structural portions can be provided in both the first and second light-transmitting structural layers. The second antenna element layer can be printed below the second light-transmitting structural portion of the first light-transmitting structural layer, which has lower light transmittance. This is more conducive to the concealment of the second antenna element layer, and thus also helps to conceal the antenna end. Similarly, the first antenna element layer can be located below the second light-transmitting structural portion of the second light-transmitting structural layer, which has lower light transmittance. This is more conducive to the concealment of the first antenna element layer, and thus also helps to conceal the antenna end.

[0160] Based on this embodiment, by printing the second antenna unit layer on the side adjacent to the second light-transmitting structure of the first light-transmitting structure, a planar structure design for the second antenna unit layer can be achieved, which can significantly reduce the overall volume and is more conducive to improving the smoothness and aesthetics of the vehicle body structure when a phased array antenna is installed.

[0161] The operating frequency of the second antenna element layer and the operating frequency of the first antenna element layer can be set based on the requirements of the actual scenario. In the relevant embodiments of this application, the operating frequency of the second antenna element layer and the operating frequency of the first antenna element layer can be set to be the same.

[0162] When the operating frequency of the second antenna element layer is the same as that of the first antenna element layer, the transmitted signals of the first antenna element layer and the second antenna element layer can be superimposed, thus achieving signal superposition. Furthermore, by strategically setting the distance between the second antenna element layer and the first antenna element layer, the peaks and troughs of their transmitted signals can overlap, thereby increasing the energy of the transmitted signal from the first antenna element layer.

[0163] In this design, the first antenna unit layer is located on the side of the roof light-transmitting structure closest to the vehicle's interior space. When the first antenna unit layer transmits its signal, the signal needs to pass through the roof light-transmitting structure before being transmitted into the air. The roof light-transmitting structure may cause some energy loss to the transmitted signal. However, due to the second antenna unit layer, which operates at the same frequency as the first antenna unit layer, the transmitted signal of the second antenna unit layer can be superimposed with the transmitted signal of the first antenna unit layer. This effectively compensates for the energy loss of the transmitted signal of the first antenna unit layer, making the transmitted signal energy of the antenna end, which includes both the first and second antenna unit layers, stable. This helps maintain and ensure the energy of the transmitted signal at the antenna end, and ultimately improves the communication performance of the antenna end.

[0164] Based on this embodiment, by setting the communication frequency of the second antenna unit layer to be the same as that of the first antenna unit layer, it is more conducive to the overlap of the peaks and troughs of the signal generated by the first antenna unit layer with the peaks and troughs of the signal generated by the second antenna unit layer. This is more conducive to compensating for the signal loss caused by the light-transmitting structure of the roof blocking the signal of the first antenna unit layer, and helps to ensure the communication performance of the antenna end.

[0165] Further integration Figure 10As shown, at the position of the roof light-transmitting structure, from bottom to top, the phase modulation chip 213 at the antenna end, the first antenna unit layer 211 at the antenna end, the second light-transmitting structure 132, the second antenna unit layer 212 at the antenna end, and the first light-transmitting structure 131 are arranged sequentially. After the phase modulation chip 213 adjusts and controls the phase of the first antenna unit layer 211 and the second antenna unit layer 212, the first antenna unit layer 211 and the second antenna unit layer 212 transmit signals according to the adjusted phase. The transmitted signal of the first antenna unit layer 211 passes through the second light-transmitting structure 132, and after being superimposed with the transmitted signal of the second antenna unit layer 212, it is transmitted into the air through the first light-transmitting structure 131.

[0166] The connection method between the first antenna unit layer 211 and the second antenna unit layer 212 is not limited. For example, the first antenna unit layer 211 and the second antenna unit layer 212 can be connected by a wire harness to achieve a wired connection between the first antenna unit layer 211 and the second antenna unit layer 212. The wire harness can be used to connect the first antenna unit layer and the second antenna unit layer through the space at the junction of the side of the roof light-transmitting structure and the vehicle body structure, but it is not limited to this.

[0167] In the relevant embodiments of this application, the second antenna unit layer and the first antenna unit layer are connected via a feeder communication.

[0168] A feeder is a wire that transmits radio frequency signals, enabling signal transmission between transmitting and receiving devices. It acts as a bridge for signal transmission in wireless communication. By using a feeder, the first antenna element layer and the second antenna element layer can be directly connected without a physical connecting wire. This eliminates the complexity of wire harness connections, further simplifies antenna installation, and improves manufacturing convenience.

[0169] It is evident that by connecting the second antenna unit layer and the first antenna unit layer through a feed line, the installation complexity of the second antenna unit layer is reduced, and the installation convenience of various components at the antenna end, such as the second antenna unit layer, is improved.

[0170] In some embodiments, the antenna end is integrated with the roof light-transmitting structure.

[0171] By integrating the independent roof light-transmitting structure with the antenna end of the phased array antenna, the overall coordination of the vehicle's roof structure can be achieved. This also helps to further reduce installation complexity, reduce external components, and improve the smoothness and aesthetics of the vehicle body structure when the phased array antenna is installed.

[0172] The location of the phase controller within the vehicle is not limited. In some examples, the phase controller is located on the main body structure of the vehicle adjacent to the roof light-transmitting structure.

[0173] The vehicle body structure refers to the basic structural part of the vehicle body. In the embodiments of this application, the phase controller can be specifically installed on the body sheet metal adjacent to the roof light-transmitting structure. The body sheet metal refers to the metal components made of thin sheet material on the vehicle body, including front and rear bumpers, doors, roof, trunk lid, hood, fenders, front / rear side panels, wheel arches, etc. The production process of body sheet metal mainly includes four steps: sheet metal preparation and cutting, sheet metal bonding, welding, and shaping and leveling.

[0174] Based on this embodiment, by setting the phase controller, which is separately set from the antenna end, on the main body structure of the vehicle body adjacent to the roof light-transmitting structure, it is possible to better control the distance between the phase controller and the antenna end while setting the phase controller separately from the antenna end. Furthermore, setting the phase controller on the main body structure of the vehicle body also facilitates the installation of the phase controller, thereby improving the ease of phase controller installation.

[0175] The specific location of the phase controller within the vehicle's main structure is not limited. In some examples, the distance between the phase controller and the roof's light-transmitting structure is within a preset range, with the upper limit of the preset range being less than the preset distance.

[0176] The specific setting of the preset range is not limited, as long as it facilitates the installation and setup of the phased array antenna and meets the communication requirements between the phased array antenna and the antenna. For example, in some embodiments, the preset range includes 20-35 mm. By setting the phased array antenna within a distance of 20-35 mm from the roof's light-transmitting structure, the communication performance between the phased array antenna and the antenna can be maintained while allowing the phased array antenna to be as close as possible to the main body structure of the vehicle. This is more conducive to the stealth setting of the phased array antenna and also helps to improve the smoothness and aesthetics of the vehicle body structure when a phased array antenna is installed.

[0177] Accordingly, by setting the phase controller at a position within a preset range from the roof light-transmitting structure, and since the antenna is located on the roof light-transmitting structure, the distance between the phase controller and the antenna can be controlled based on the control of the distance from the roof light-transmitting structure. This facilitates the convenience and efficiency of setting the phase controller position and can reduce the impact of vibrations during vehicle operation on devices located below the roof light-transmitting structure.

[0178] In some specific examples, the phase controller is located on the adjacent main body structure below the roof light-transmitting structure where the antenna is located.

[0179] Based on this embodiment, the vehicle-mounted phased array antenna, by setting the phase controller on the main body structure adjacent to the roof light-transmitting structure where the antenna end is located, allows the phase controller to be placed as close as possible to the antenna end, which helps to improve the signal transmission performance between the antenna end and the phase controller, thereby improving the communication performance of the vehicle-mounted phased array antenna.

[0180] In a specific example, the phase controller is disposed on the main body structure of the vehicle body adjacent to the first side of the first light-transmitting structure portion, and the first side of the first light-transmitting structure portion is the side away from the second light-transmitting structure portion.

[0181] Accordingly, by placing the phase controller adjacent to the first light-transmitting structure portion with relatively high light transmittance in the vehicle's light-transmitting structure, and on the main body structure of the vehicle body adjacent to the first side of the first light-transmitting structure portion, while the first side of the first light-transmitting structure portion is the side away from the second light-transmitting structure portion with relatively low light transmittance, it is not necessary to restrict the phase controller to a position adjacent to the antenna end. The phase controller can be set based on the vehicle body volume, which helps to further improve the convenience of determining the position of the phase controller.

[0182] Based on the vehicle-mounted phased array antennas described above, a detailed explanation is provided below with reference to a specific example. In this example, refer to... Figure 11 As shown, the antenna end and phase controller of the vehicle-mounted phased array antenna are designed separately. The antenna end is integrated with the vehicle's roof light-transmitting structure, which is a panoramic glass, and the phase controller is located on the body sheet metal below the roof light-transmitting structure.

[0183] The antenna end of the vehicle-mounted phased array antenna is located on the right side of the rear black border area of ​​the vehicle's sunroof (i.e., the second light-transmitting structure part with lower light transmittance) (near the rear of the vehicle). The left side of the rear black border area is the TBOX (Total Block Oxide Array) placement area. The antenna end and the TBOX as a whole do not extend beyond the rear black border area, achieving a concealed arrangement. The antenna end includes a transmitting array and a receiving array. The receiving array is close to the TBOX, and the transmitting array is far from the TBOX, close to the right edge of the vehicle.

[0184] The roof light-transmitting structure consists of two layers of glass, namely a first light-transmitting layer and a second light-transmitting layer. The antenna end includes a first antenna element layer and a second antenna element layer. The second antenna element layer serves as the image layer for the phased array antenna and is printed on the second surface of the glass interlayer using a silver plating method, specifically on the side of the first light-transmitting layer closest to the vehicle's interior space. The first antenna element layer, serving as the antenna body of the vehicle-mounted phased array antenna, is attached to the bottom of the interior glass along with the phase modulation chip, specifically on the side of the second light-transmitting layer closest to the vehicle's interior space.

[0185] The phase controller 202 is separate from the antenna and is located on the lower right side of the vehicle body structure in the direction of the panoramic glass, at a distance of 20-35mm from the panoramic glass. It communicates with the antenna via a feed line and has the capability of phase algorithm and phase control. The phase controller collects the signals relayed by the phase modulation chip 213 at the antenna end, calculates the phase value corresponding to each antenna array element in the current first and second antenna element layers, and then adjusts the phase of each phase modulation chip 213 at the antenna end through the phase control unit to achieve beam adjustment.

[0186] The TBOX communicates with the phase controller, and the collaborative workflow between the vehicle-mounted phased array antenna and the TBOX can be as follows:

[0187] After the vehicle is powered on, the onboard phased array antenna receives satellite signals and transmits the signal strength of the received satellite signals to the phase controller via the phase modulation chip 213. The phase controller's phase calculation module calculates the satellite position based on the received signal strength and outputs the phase adjustment data of each antenna to the phase modulation chip 213 via the phase control module. The phase modulation chip 213 adjusts the phase of each antenna to change the radiation direction of the antenna, ensuring that the direction facing the satellite is the strongest radiation direction. Finally, the phase controller 202 outputs the latest satellite signal and transmits it to the satellite communication module of the TBOX via the feeder, realizing data reception and transmission.

[0188] Based on the vehicle-mounted phased array antennas of the embodiments described above, this application also provides a vehicle, wherein the vehicle includes a main body structure and a roof light-transmitting structure, and the vehicle is further provided with the vehicle-mounted phased array antenna described in any of the embodiments above.

[0189] Based on this embodiment, the vehicle features a separate onboard phased array antenna with the antenna end and phase controller separately mounted on the vehicle. The antenna end is located on the roof light-transmitting structure, while the phase controller is located in other parts of the vehicle. This allows the smaller antenna end to be mounted together with the roof light-transmitting structure, eliminating the need to mount both the antenna end and the phase controller on the roof. This avoids the need for the phased array antenna to protrude from the roof and improves the smoothness and aesthetics of the vehicle body structure when the phased array antenna is mounted.

[0190] In this embodiment, the vehicle's onboard phased array antenna features a separate design for the antenna end and the phased array itself, eliminating the need to modify the vehicle's exterior and preserving its aesthetics. This also avoids the problem of existing phased array antennas being too large to be installed inside the vehicle, requiring mounting on the roof like a roof rack, which obstructs the view of passengers through the roof glass. Furthermore, by integrating the antenna end into the roof glass, the metal bracket and housing of existing phased array antennas are eliminated. When integrated with the roof glass, the first antenna unit layer can be bonded to the phase modulation chip without the need for a dedicated dielectric material layer, reducing antenna consumables and achieving cost savings and weight reduction. The onboard phased array antenna can operate in the Ka band, which has a frequency range of 26.5~40GHz. This wide frequency band enables the vehicle to achieve high-speed satellite communication capabilities in the Ka band, allowing passengers to enjoy high-speed satellite communication services anytime, anywhere outdoors.

[0191] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0192] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
