Description

Technical Field

[0001] This application relates to the field of communication technology, and more specifically, to a feed adapter for connection with an antenna. Background Technology

[0002] In recent years, with the development of communication technology, vehicle-to-everything (V2X) technology has become increasingly mature. V2X demands higher network bandwidth and transmission rates, facilitating human-vehicle communication, vehicle-to-vehicle communication, and communication between vehicles and external systems. This has led to increasingly stringent requirements for vehicle antenna types. With the increasing glass coverage of automobiles, the concept of automotive glass antennas has emerged. Most cars use T-BOX antennas or shark fin antennas. However, T-BOX antennas, installed inside the vehicle body, can cause signal shielding issues, while shark fin antennas can interfere with panoramic sunroof designs. Currently, glass antennas can solve these problems. However, designing glass antennas requires addressing the challenge of feeding antennas between different media and ensuring low signal loss during transmission. The feeding methods used for T-BOX or shark fin antennas cannot be applied to glass antennas. Summary of the Invention

[0003] The purpose of this application is to provide a power supply adapter for connecting to an antenna, which can be electrically connected to a nano-silver antenna in an insulating transparent rigid substrate, thereby achieving characteristic impedance matching of the antenna body and ensuring that the antenna signal is transmitted to the RF module end with low loss through the power supply adapter.

[0004] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0005] This application provides a feed converter for connection with an antenna, comprising: a feed converter for electrical connection with a nano-silver antenna in an insulating transparent rigid substrate, a portion of the feed converter for bonding with the insulating transparent rigid substrate, the feed converter being a flexible component, and the impedance of the feed converter being used together with the impedance of the nano-silver antenna to achieve a preset impedance of the antenna body.

[0006] In the implementation of the above scheme, the feed adapter includes a feed conversion component electrically connected to the nano-silver antenna. During installation, a portion of the feed conversion component is attached to the insulating transparent rigid substrate, while the other portion protrudes from the substrate. The feed conversion component is a flexible component, which is relatively flexible and easily deformable to ensure the reliability of the connection with the insulating transparent rigid substrate. This allows the feed conversion component and the nano-silver antenna to be designed as a whole, and the impedance of the two components meets the preset requirements of the antenna body impedance. This realizes the feed connection method of the feed adapter in the insulating transparent rigid substrate with the nano-silver antenna, without the need for additional control of other transmission impedance lines. It achieves characteristic impedance matching between the feed adapter and the nano-silver antenna in the insulating transparent rigid substrate, thereby minimizing the transmission loss of the antenna signal.

[0007] In one embodiment, the power conversion device includes a conductive component and a power conversion body, wherein the conductive component is disposed on the power conversion body and is used for electrical connection with the nano-silver antenna.

[0008] In the implementation of the above scheme, the feed conversion device includes a feed conversion body and a conductive component. The conductive component is disposed on the feed conversion body and is used to electrically connect with the nano-silver antenna. Thus, when the feed conversion device is connected to the nano-silver antenna, the feed conversion device and the nano-silver antenna are an integral structure, completing the electrical connection between the feed conversion device and the nano-silver antenna. This achieves characteristic impedance matching between the feed conversion device and the nano-silver antenna in the insulating transparent rigid substrate, thereby minimizing the transmission loss of the antenna signal.

[0009] In one embodiment, the power supply conversion body is provided with at least one adhesive gripping hole.

[0010] In the process of implementing the above solution, at least one adhesive-holding hole is provided on the power supply conversion body. When the power supply conversion body is bonded to the insulating transparent rigid substrate, the UV (Ultraviolet Rays) adhesive, i.e. shadowless adhesive, will melt in the adhesive-holding hole, which can enhance the stability between the power supply conversion body and the insulating transparent rigid substrate.

[0011] In one implementation, the power supply conversion component may be an FPC, an MPI flexible circuit board, or an LCP flexible circuit board.

[0012] In the implementation of the above solution, the power conversion component can be one of FPC (Flexible Printed Circuit), MPI (Modified PI), or LCP (Liquid Crystal Polymer) as a flexible component. This ensures the flexibility of the power conversion component and makes it easier to bond with the insulating transparent rigid substrate. In addition, when the insulating transparent rigid substrate adopts a double-layer structure, the power conversion component is set in the sandwich of the insulating transparent rigid substrate. The flexibility of the power conversion component makes it easy to place the power conversion component in the sandwich and can realize the pressing of the insulating transparent rigid substrate, as well as ensure the sealing between the insulating transparent rigid substrate and the power conversion component.

[0013] In one embodiment, the insulating transparent rigid substrate includes glass, the glass including laminated glass, and a portion of the power supply conversion element is located in the laminate.

[0014] In the process of implementing the above scheme, the insulating transparent rigid substrate includes glass, the glass includes laminated glass, the nano silver antenna and the feed conversion component are partially disposed in the interlayer, thereby increasing the stability between the feed conversion component and the laminated glass. In addition, the feed conversion component and the nano silver antenna are integrated into a whole, and the characteristic impedance of the two components reaches the preset impedance of the antenna body, thus achieving impedance matching of the antenna body.

[0015] In one implementation, the electrical connection between the conductive component and the nano-silver antenna is achieved by high-temperature pressing of an anisotropic conductive film onto the power supply conversion body.

[0016] In the process of implementing the above scheme, the electrical connection between the conductive component and the nano-silver antenna is achieved by hot-pressing anisotropic conductive film onto the feed conversion body at high temperature, which ensures the stability of the connection between the conductive component and the nano-silver antenna. This realizes that the nano-silver antenna and the feed conversion component are integrated into a single structure, which facilitates impedance matching of the antenna body.

[0017] In one implementation, the electrical connection between the conductive component and the nano-silver antenna is located close to one side of the feed conversion body, so that the electrical connection is located in the interlayer.

[0018] In the process of implementing the above scheme, the electrical connection position between the conductive component and the nano-silver antenna is close to the side of the feed conversion body. This allows the electrical connection position between the conductive component and the nano-silver antenna to also be located in the interlayer of glass when the feed conversion body is located in the interlayer, thus protecting the electrical connection position and ensuring its stability.

[0019] In one embodiment, the conductive component and the nano-silver antenna are plated with gold at the electrical connection points on the feed conversion body.

[0020] In the process of implementing the above scheme, gold has extremely strong oxidation resistance, which can protect the internal circuit from corrosion. It also has strong conductivity, which will not cause signal loss. At the same time, gold has very strong ductility, which can increase the contact area between the nano-silver antenna and the conductive component at the electrical connection point on the feed conversion body under appropriate pressure, thereby reducing the contact resistance, achieving impedance matching of the antenna and improving signal transmission efficiency.

[0021] In one embodiment, the conductive component includes a first conductive sheet and a second conductive sheet, with a gap between the first conductive sheet and the second conductive sheet.

[0022] In the process of implementing the above scheme, the conductive component includes a first conductive sheet and a second conductive sheet. A gap is set between the first conductive sheet and the second conductive sheet to ensure the radiation of the antenna. The gap can be tuned to a resonance of 3300-6000MHz, thereby realizing the adjustment of the antenna impedance to meet the impedance matching requirements of the whole consisting of the nano-silver antenna and the feed conversion component with the coaxial cable.

[0023] In one embodiment, the power conversion device further includes a coaxial cable, which is electrically connected to the first conductive sheet and the second conductive sheet respectively.

[0024] In the process of implementing the above scheme, the power conversion device also includes a coaxial cable, which is electrically connected to the first conductive sheet and the second conductive sheet respectively, so as to transmit the signal received by the nano-silver antenna to the radio frequency module.

Detailed Implementation

[0030] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0031] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figure 1 and 2 As shown in the embodiment of this application, a feed adapter for connection with an antenna is described. The feed adapter includes a feed conversion component 3 electrically connected to a nano-silver antenna 1. A portion of the feed conversion component 3 is attached to an insulating transparent rigid substrate 6, while another portion protrudes from the insulating transparent rigid substrate 6. The contact area between the feed conversion component 3 and the insulating transparent rigid substrate 6 can be adjusted according to actual needs. The feed conversion component 3 is made of a flexible material to ensure the reliability of the connection with the insulating transparent rigid substrate 6. This allows the nano-silver antenna 1 and the feed conversion component 3 to be designed as a whole, and the impedance of the two components meets the preset impedance requirements of the antenna body. This realizes the feed connection method of the feed adapter in the insulating transparent rigid substrate 6 with the nano-silver antenna 1, and completes the characteristic impedance matching between the feed adapter and the nano-silver antenna 1 in the insulating transparent rigid substrate 6. There is no need to control other transmission impedance lines, thereby minimizing the transmission loss of the antenna signal.

[0033] In addition, the power supply adapter in this application embodiment has the advantages of low signal loss conversion, stable installation, easy mass production, and low cost, and effectively solves the power supply problem of nano-silver antennas in insulating transparent rigid substrates.

[0034] Optionally, the nano-silver antenna 1 is made of nano-silver wire, because nano-silver wire can be thin enough. When the nano-silver antenna 1 is placed on the insulating transparent rigid substrate 6, it can reduce the influence on the viewing angle of the insulating transparent rigid substrate 6, thereby ensuring the light transmittance of the insulating transparent rigid substrate 6.

[0035] Optionally, the antenna body includes a nano-silver antenna and a feed converter. The optimal performance of the antenna body can be achieved through impedance matching. The preset impedance of the antenna body can be 50 ohms. However, it is difficult to achieve a specific 50 ohms in actual testing. Therefore, the preset impedance of the antenna body in this embodiment can be a preset range, that is, the sum of the impedances of the nano-silver antenna 1 and the feed converter 3 can be close to 50 ohms. Of course, the nano-silver antenna 1 also has a certain dielectric loss in the insulating transparent rigid substrate 6. Therefore, in some cases, the system impedance of the nano-silver antenna 1, the feed converter 3, and the insulating transparent rigid substrate 6 can also be designed to be close to 50 ohms.

[0036] Optionally, the nano-silver antenna 1 can be designed to include at least one first antenna branch 11, a second antenna branch 12, and a third antenna branch 13. Designing the nano-silver antenna 1 as three antenna branches increases the frequency bandwidth of the nano-silver antenna 1, ensures the frequency coverage of the nano-silver antenna 1, and supports multi-mode and multi-scenario antenna design requirements.

[0037] Optionally, each antenna branch of the nano-silver antenna 1 is formed by nano-silver wires in a grid shape. The shape of each antenna branch can be irregular, and this application embodiment does not make specific limitations.

[0038] Optionally, the power supply adapter is not limited to being electrically connected to a single nano-silver antenna 1 in this application, but can also be electrically connected to multiple nano-silver antennas 1, and each nano-silver antenna 1 can receive different signals, such as GPS signals, WIFI signals, etc.

[0039] like Figure 1 As shown, in one embodiment, the feed converter 3 includes a conductive component 2 and a feed converter body 32. The conductive component 2 is disposed on the feed converter body 32 and is used to electrically connect with the nano-silver antenna 1. Thus, when the feed converter is connected to the nano-silver antenna 1, the feed converter 3 and the nano-silver antenna 1 are an integral structure, completing the electrical connection between the feed converter 3 and the nano-silver antenna 1. This achieves characteristic impedance matching between the feed converter and the nano-silver antenna 1 in the insulating transparent rigid substrate 6, thereby minimizing the transmission loss of the antenna signal.

[0040] like Figure 1 As shown, optionally, the conductive component 2 includes a first conductive sheet 21 and a second conductive sheet 22. The first conductive sheet 21 and the second conductive sheet 22 can be designed as a symmetrical structure, or they can be designed as an asymmetrical shape. The first conductive sheet 21 is used to electrically connect the first antenna branch 11 and the third antenna branch 13, and the second conductive sheet 22 is electrically connected to the second antenna branch 12.

[0041] Optionally, the first conductive sheet 21 and the second conductive sheet 22 are embedded in the power supply conversion body 32, while the conductive component 2 in this embodiment can be a copper foil layer. The copper foil layer has flexibility and can be made into many thicknesses and widths. In addition to flexibility, the copper foil layer also has the characteristics of being hard and smooth, making it suitable for applications requiring dynamic bending.

[0042] Optionally, the power supply adapter is not limited to electrical connection between the conductive component 2 and the multiple nano-silver antenna 1 branches, or it may not be electrically connected.

[0043] Optionally, the area of ​​the power supply conversion component 3 can be appropriately increased, and the area of ​​the conductive component 2 can also be increased. Furthermore, an active surface mount circuit can be designed on the increased area of ​​the conductive component 2, thereby increasing the applicability of the power supply conversion device.

[0044] like Figure 1 As shown, in one embodiment, at least one adhesive-holding hole 31 is provided on the power supply conversion body 32. When the power supply conversion body 32 is bonded to the insulating transparent rigid substrate 6, the UV (Ultraviolet Rays) adhesive, i.e., shadowless adhesive, will be hot-melted in the adhesive-holding hole 31, which can enhance the stability between the power supply conversion body 32 and the insulating transparent rigid substrate 6.

[0045] Optionally, the power conversion body 32 is provided with two adhesive-holding holes 31, and the two adhesive-holding holes 31 are respectively located on both sides of the power conversion body 32. When the power conversion body 32 is bonded to the insulating transparent rigid substrate 6, UV adhesive is hot-pressed into the two adhesive-holding holes 31, further increasing the stability between the power conversion body 32 and the insulating transparent rigid substrate 6.

[0046] As one implementation method, the power conversion component 3 can be one of FPC, MPI flexible board, or LCP flexible board. Because FPC, MPI flexible board, and LCP flexible board are all flexible components, the flexibility of the power conversion component 3 is guaranteed, making it easier to bond with the insulating transparent rigid substrate 6. In addition, when the insulating transparent rigid substrate 6 adopts a double-layer structure, the power conversion component 3 is disposed in the interlayer of the insulating transparent rigid substrate 6. The flexibility of the power conversion component 3 makes it easy to be disposed in the interlayer, and can realize the pressing of the insulating transparent rigid substrate 6, as well as ensure the sealing between the insulating transparent rigid substrate 6 and the power conversion component 3.

[0047] Alternatively, the power supply conversion element 3 can also be made of other flexible materials.

[0048] In one embodiment, the insulating transparent rigid substrate 6 includes glass, which includes laminated glass and a thin film located in the interlayer. The nano-silver antenna 1 and the feed conversion component 3 are partially disposed in the interlayer, thereby increasing the stability between the feed conversion component 3 and the laminated glass. In addition, the feed conversion component 3 and the nano-silver antenna 1 are integrated into a whole, and the impedance of the two components reaches the preset impedance of the antenna body, thereby achieving impedance matching of the antenna body.

[0049] like Figure 2 As shown, optionally, the insulating transparent rigid substrate 6 can be glass, which may include two glass sheets and a thin film located between the two glass sheets. The thin film is made of 0.76mm PET (polyethylene glycol terephthalate), and PET film 61 is selected to meet the process requirements for the preparation of silver nanowires. The two glass sheets can be bonded together using optical adhesive 62. According to the present invention, the silver nanowire antenna 1 and the feed conversion component 3 are partially heat-pressed into the sandwich of the two glass sheets by PET film 61. In addition, the feed conversion component 3 is made of a flexible material, whose flexibility makes it easier to heat-press into the sandwich.

[0050] Optionally, the glass may also include a single layer of glass. When a single layer of glass is used, the nano-silver antenna 1 can be printed on one side of the single layer of glass, and the feed conversion component 3 is connected to the single layer of glass by hot pressing.

[0051] Optionally, the glass can be flat or curved, and it can be used on the windshield or rear windshield of a car, or in other places.

[0052] Optionally, the insulating transparent rigid substrate 6 can also be a transparent plastic.

[0053] In one implementation, the position where the conductive component 2 is electrically connected to the nano-silver antenna 1 in the laminated glass is hot-pressed onto the feed conversion body 32 at high temperature using an anisotropic conductive adhesive film. This ensures the stability of the connection between the conductive component 2 and the nano-silver antenna 1, thereby realizing that the nano-silver antenna 1 and the feed conversion component 3 are an integral structure, which facilitates impedance matching of the antenna body.

[0054] Optionally, the first conductive sheet 21 is hot-pressed onto the feed conversion body 32 with the first antenna branch 11 and the third antenna branch 13 using anisotropic conductive adhesive film at high temperature. The second conductive sheet 22 is hot-pressed onto the feed conversion body 32 with the second antenna branch 12 using anisotropic conductive adhesive film at high temperature. This achieves a single integrated structure for the first conductive sheet 21, the second conductive sheet 22, the first antenna branch 11, the second antenna branch 12, the third antenna branch 13, and the feed conversion body 32. This satisfies the impedance matching of the antenna body and makes the connection structure between the above components more stable, facilitating hot pressing within the double-layer glass and ensuring stability.

[0055] like Figure 1 As shown, in one embodiment, the electrical connection position between the conductive component 2 and the nano-silver antenna 1 is close to the side of the feed conversion body 32. This allows the electrical connection position between the conductive component 2 and the nano-silver antenna 1 to also be located in the interlayer of glass when the feed conversion body 32 is located in the interlayer, thus protecting the electrical connection position and ensuring its stability.

[0056] Optionally, the electrical connection position between the conductive component 2 and the nano-silver antenna 1 can be close to the upper side of the feed conversion component 3. In some cases, it can also be close to the lower side, left side, or right side. This application does not specifically limit its electrical connection position.

[0057] As one implementation method, the electrical connection points between the conductive component 2 and the nano-silver antenna 1 on the surface of the feed conversion body 32 are plated with gold. This is because gold has extremely strong oxidation resistance, which can protect the internal circuit from corrosion. Moreover, it has strong conductivity and will not cause signal loss. At the same time, gold has very strong ductility, which can increase the contact area between the nano-silver antenna 1 and the conductive component 2 at the electrical connection points on the feed conversion body 32 under appropriate pressure, thereby reducing the contact resistance, achieving impedance matching of the antenna body, and improving signal transmission efficiency.

[0058] like Figure 3 As shown, in one embodiment, the conductive component 2 includes a first conductive sheet 21 and a second conductive sheet 22. A gap is provided between the first conductive sheet 21 and the second conductive sheet 22 to ensure the radiation of the antenna body. The gap can be tuned to a resonance of 3300-6000MHz, thereby realizing the impedance adjustment of the antenna body to meet the impedance matching requirements of the system consisting of the nano-silver antenna 1, the conductive component 2 and the feed conversion component 3 with the impedance of the coaxial cable 4.

[0059] like Figure 3As shown, optionally, the gap includes three first connecting gaps 7, two second connecting gaps 8, and two third connecting gaps 9. The three first connecting gaps 7 form an unsealed quadrilateral. The two second connecting gaps 7 are located on both sides of the second conductive sheet 22 and are connected to two of the first connecting gaps 7 respectively. The width of the second connecting gaps 8 gradually increases in the direction away from the first connecting gaps 7. The two third connecting gaps 9 are connected to the two second connecting gaps 8 respectively, thereby enabling the gap to be tuned to a resonance of 3300-6000MHz.

[0060] Optionally, when the structure of the first conductive sheet 21 and the second conductive sheet 22 changes, the gap between the first conductive sheet 21 and the second conductive sheet 22 will also change.

[0061] like Figure 1 and 2 As shown, in one embodiment, the antenna also includes a coaxial cable 4, which is electrically connected to the first conductive sheet 21 and the second conductive sheet 22, thereby transmitting the signal received by the nano-silver antenna 1 to the radio frequency module.

[0062] Optionally, the end of the coaxial cable 4 away from the nano-silver antenna 1 has a Fakra adapter 5, which is detachably connected to the coaxial cable 4, thereby enabling the antenna to be plugged into different RF module terminals. Of course, the RF module terminal can be an RF module terminal in automobiles or an RF module terminal in other fields such as ships.

[0063] Optionally, the coaxial cable 4 can be a standard 50-ohm impedance cable, which makes it easier to achieve impedance matching of the antenna body and ensure the signal transmission efficiency of the coaxial cable 4. The coaxial cable 4 includes a core layer and a shielding layer. The shielding layer is located on the outer periphery of the core layer. The shielding layer is welded to the first conductive sheet 21, and the core layer is welded to the second conductive sheet 22.

[0064] Optionally, since two adhesive-holding holes 31 are provided on both sides of the power supply conversion component 3, when the coaxial cable 4 is welded to the conductive component 2, the coaxial cable 4 is located outside the insulating transparent rigid substrate 6, and the UV adhesive in the adhesive-holding hole 31 can increase the tensile force of the coaxial cable 4 borne by the power supply conversion component 3, further ensuring the stability between the power supply conversion component 3 and the insulating transparent rigid substrate 6.
