Description

Technical Field

[0001] This application relates to the field of antenna technology, and in particular to an antenna, antenna assembly, and electronic device. Background Technology

[0002] Antennas are essential components in wireless devices, such as Wi-Fi routers, used to transmit or receive electromagnetic waves. In related technologies, a router includes a casing, an antenna assembly, and a motherboard. Both the antenna assembly and the motherboard are located inside the casing. The motherboard is fixedly connected to the bottom wall of the casing, and the antenna assembly is fixedly connected to the side wall of the casing. The antenna assembly includes a circuit board, a dipole antenna, and a coaxial cable. The dipole antenna is printed on the circuit board and is electrically connected to the motherboard via the coaxial cable. The circuit board is fixedly connected to the inner wall of the casing. To improve antenna gain, the antenna is typically designed to be large, resulting in a large casing and a large overall router size. This makes the router appear obtrusive on a desktop, thus reducing the user experience. Utility Model Content

[0003] This application provides an antenna, an antenna assembly, and an electronic device, which can improve the phenomenon that electronic devices are difficult to integrate into the environment and appear obtrusive.

[0004] In a first aspect, embodiments of this application provide an antenna, which includes a first electrical connector, a second electrical connector, a first line, and a second line. The first electrical connector is configured to be electrically connected to a feed structure. The second electrical connector is configured to be electrically connected to the feed structure. The first line is electrically connected to the first electrical connector. The second line is spaced apart from the first line and electrically connected to the second electrical connector. Along the arrangement direction of the first and second electrical connectors, the maximum distance between the bottom end of the second line and the bottom end of the second electrical connector is less than or equal to one-eighth of the operating wavelength of the antenna. When current flows through both the first and second lines, in the arrangement direction of the first and second electrical connectors, the current direction of the first current on the first line is opposite to the current direction of the second current on the second line.

[0005] When the antenna provided in this embodiment is integrated into an electronic device with transparent and non-transparent areas, the maximum distance between the bottom end of the second line and the bottom end of the second electrical connector is less than or equal to one-eighth of the antenna's operating wavelength, allowing for a shorter distance between the second electrical connector and the bottom end of the antenna. This reduces the height requirement for the non-transparent area. While maintaining the same height for the electronic device, the height of the transparent area can be increased while decreasing the height of the non-transparent area. This helps increase the transparent area of ​​the electronic device, further reducing the obstruction area around the device and allowing it to blend better into its surroundings without appearing obtrusive.

[0006] In addition, when current flows through both the first and second lines, since the maximum distance between the bottom end of the second line and the bottom end of the second electrical connector is less than or equal to one-eighth of the antenna's operating wavelength, and the current direction of the first current on the first line is opposite to that of the second current on the second line in the arrangement direction of the first and second electrical connectors, the radiation generated by the first and second lines can cancel each other out in the far field, thereby reducing the impact on the electromagnetic signals radiated by the antenna and improving antenna performance.

[0007] In some possible implementations, the ratio of the minimum line width of the first line to the maximum line width of the second line is greater than or equal to 1 and less than or equal to 2. This setting allows the impedance of the first and second lines to be controlled within a reasonable range, ensuring that the magnitudes of the first and second currents are essentially the same. This allows the radiation generated by the first and second lines to cancel each other out, thus avoiding and reducing the impact on the electromagnetic signals radiated by the antenna.

[0008] In some possible implementations, the second circuit is a symmetrical structure about an axis of symmetry parallel to the arrangement direction of the first and second electrical connectors. This configuration allows the antenna to form an omnidirectional radiation pattern in the far field, improving its radiation range and enhancing the user experience of electronic devices.

[0009] In some possible implementations, the first line includes a radiator, such that at least a portion of the first line can act as a radiator, and the first line can radiate electromagnetic signals.

[0010] In some possible implementations, the antenna also includes a radiator, to which a first line is coupled. This allows the first line to directly or coupled-feed the radiator to excite it to radiate electromagnetic signals.

[0011] In some possible implementations, the radiator is at least partially transparent. By making at least a portion of the radiator located in the transparent area transparent, a user can see objects behind the radiator through the transparent portion, allowing the antenna to better integrate into the surrounding environment of the electronic device and further enabling the electronic device to blend more seamlessly into its surroundings without appearing obtrusive.

[0012] In some possible implementations, at least part of the radiator is a metal mesh structure. This allows for the fabrication of very fine first metal lines using metal mesh circuitry, ensuring that the transmittance of the radiator formed by the intersection of multiple first metal lines meets requirements, for example, achieving a transmittance of 85%, thus realizing transparency. Furthermore, the metal mesh circuitry allows for control of the resistance of the first metal lines within a reasonable range, resulting in good conductivity and improving the radiator's radiation efficiency.

[0013] In some possible implementations, the radiator includes multiple intersecting first metal lines, with linewidths ranging from 3µm to 20µm. This arrangement results in very fine linewidths of the first metal lines, making them inconspicuous to the naked eye, thus ensuring the radiator's transmittance meets requirements and achieving a transparent effect. Furthermore, setting the linewidth of the first metal lines to 3µm to 20µm allows for compatibility with existing processes and reduces manufacturing costs.

[0014] In some possible implementations, the radiator is made of a transparent metallic material. It can also be made transparent, allowing users to see objects behind it.

[0015] In some possible implementations, the antenna also includes a carrier that is at least partially transparent, with at least a portion of the radiator disposed on the transparent portion of the carrier. This allows at least a portion of the transparent portion of the carrier to be located within a transparent area, enabling the user to see objects behind the carrier through the transparent portion. This reduces the area of ​​the antenna obstructing the surrounding environment, helping electronic devices to blend better into their surroundings without appearing obtrusive.

[0016] In some possible implementations, the antenna also includes a transparent protective layer, with the radiator located between the carrier and the transparent protective layer. In this way, the transparent protective layer, the radiator, and the carrier can form a sandwich structure, and the transparent protective layer can protect the radiator, preventing damage to the radiator and improving the reliability of the antenna.

[0017] In some possible implementations, when the first line is coupled to the radiator, at least a portion of the first line is transparent. This allows the portion of the first line located in the transparent area to be made transparent, enabling the user to see objects behind it. This allows the antenna to better integrate into the surrounding environment of the electronic device, further enhancing its integration without appearing obtrusive.

[0018] In some possible implementations, at least a portion of the first line is parallel to the second line. This can further enhance the cancellation effect of the radiation generated by the first and second lines in the far field, helping to further reduce the influence of the second line on the electromagnetic signals radiated by the antenna, thereby further improving antenna performance.

[0019] In some possible implementations, the direction of the first current is opposite to the direction of the second current in the section where the first and second lines are parallel. This arrangement allows the radiation generated by the first and second lines to almost completely cancel each other out in the far field, which helps to further improve antenna performance.

[0020] In some possible implementations, at least a portion of the second line is transparent. This allows the portion of the second line located within a transparent area to be set to transparent, enabling users to see objects behind it. This allows the antenna to better integrate into the surrounding environment of the electronic device, further enhancing its integration without appearing obtrusive.

[0021] In some possible implementations, the first electrical connector includes a pad, and / or the second electrical connector includes a pad. This allows the first and second electrical connectors to be manufactured using existing processes, helping to reduce manufacturing difficulty and antenna cost. Alternatively, soldering can be used to electrically connect the first and second electrical connectors to the feed structure, reducing the difficulty of electrically connecting the feed structure to the first and second electrical connectors.

[0022] In some possible implementations, the antenna also includes a feeding structure. This integration of the feeding structure into the antenna simplifies the assembly process of the electronic device.

[0023] In some possible implementations, the feeding structure includes a coaxial line comprising an inner conductor and an outer conductor, one of which is electrically connected to a first electrical connector and the other to a second electrical connector. This allows for a reduction in antenna cost while still meeting the antenna's operational requirements.

[0024] Secondly, embodiments of this application provide an antenna assembly including a feeding structure and an antenna as described in any of the first aspects. In this way, the antenna and the feeding structure are two parallel components.

[0025] In some possible implementations, the feeding structure includes a coaxial line comprising an inner conductor and an outer conductor, one of which is electrically connected to a first electrical connector and the other to a second electrical connector. This allows for a reduction in antenna cost while still meeting the antenna's operational requirements.

[0026] Thirdly, embodiments of this application provide an electronic device that includes at least one antenna as described in any of the first aspects, or the electronic device includes at least one antenna assembly as described in any of the second aspects.

[0027] In some possible implementations, the electronic device includes a transparent region and a non-transparent region, with at least a portion of the antenna's radiator located in the transparent region.

[0028] Because the transparent area is transparent, users can see objects behind the electronic device through it, reducing the area the electronic device obstructs from its surroundings and allowing it to blend more easily into the environment without appearing obtrusive. Furthermore, since the second and third feed points are both located in the non-transparent area, reducing the height of the non-transparent area helps increase the height of the transparent area, further enhancing the integration of the electronic device into its environment.

[0029] In some possible implementations, the portion of the radiator located in the transparent area is transparent. This configuration allows the transparent portion of the radiator to blend into the surrounding environment, enabling the electronic device to integrate better into its surroundings without appearing obtrusive.

[0030] In some possible implementations, at least a portion of the first line is located in a non-transparent area, and / or at least a portion of the second line is located in a non-transparent area. This arrangement reduces the area of ​​the first and second lines obstructing the surrounding environment, allowing the electronic device to blend more seamlessly into its surroundings without appearing obtrusive.

[0031] In some possible implementations, the electronic device also includes a housing, with one part of the housing located in a transparent area and another part in a non-transparent area. The transparent portion of the housing is transparent, and the antenna is located inside the housing. This configuration allows the user to see objects behind the housing, enabling the housing to better blend into its surroundings.

[0032] In some possible implementations, at least a portion of the antenna is attached to the inner wall of the housing, or the antenna is spaced apart from the inner wall of the housing. This reduces the requirements for antenna placement. Furthermore, when the antenna is attached to the inner wall of the housing, the larger area of ​​the inner wall allows for a larger antenna size, which helps to improve antenna gain.

[0033] In some possible implementations, the electronic device also includes a transparent inner shell located inside the main body, with at least a portion of the transparent inner shell situated within a transparent area, and at least a portion of the antenna disposed within the transparent inner shell. This arrangement protects the antenna and prevents damage to it.

[0034] In some possible implementations, the electronic device includes a router or a speaker. Attached Figure Description

[0068] The terminology used in the implementation section of this application is for the purpose of explaining specific embodiments of this application only, and is not intended to limit this application.

[0069] This application provides an electronic device, which may include, but is not limited to, routers, speakers, customer premise equipment (CPE), mobile phones, tablets, televisions, smart wearable products (e.g., smartwatches, smart bracelets), virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, and other electronic products capable of wireless signal transmission. For ease of explanation, the following description uses a wireless-fidelity (Wi-Fi) router as an example.

[0070] Figure 1 This is a schematic diagram of a router structure in related technologies.

[0071] See Figure 1 Router 900 includes a housing 910, an antenna device 920, and a motherboard 930. Both the antenna device 920 and the motherboard 930 are located inside the housing 910. The motherboard 930 is fixedly connected to the bottom wall of the housing 910, and the antenna device 920 is fixedly connected to the side wall of the housing 910. The antenna device 920 includes a circuit board 921, a dipole antenna 922, and a coaxial cable 923. The circuit board 921 is fixedly connected to the inner wall of the housing 910. The dipole antenna 922 is printed on the circuit board 921 and includes a first radiating plate 9221 and a second radiating plate 9222, extending along the height direction of the router 900 (e.g., along the height direction of the router 900). Figure 1 In the Z-direction, the lengths of the first radiating plate 9221 and the second radiating plate 9222 are both greater than one-eighth of the operating wavelength of the dipole antenna 922. The first radiating plate 9221 is electrically connected to the inner conductor of the coaxial line 923, and the second radiating plate 9222 is electrically connected to the outer conductor of the coaxial line 923. The main board 930 is electrically connected to the dipole antenna 922 through the coaxial line 923.

[0072] However, in order to improve antenna gain, the antenna is designed to be large in height, which results in a large casing for the 910, making the overall size of the router 900 quite large. This makes it look out of place on a desktop, thus reducing the user experience.

[0073] Figure 2 This is a schematic diagram of another router structure based on related technologies.

[0074] In one implementation, see Figure 2The router 900 also includes multiple support components 940, located on the same side of the outer casing 910. One end of each support component 940 is movably connected to the side wall of the outer casing 910. The dipole antenna 922 is housed inside the support component 940, and the mainboard 930 is located inside the outer casing 910. Therefore, placing the dipole antenna 922 outside the outer casing 910 reduces the height and overall size of the casing 910. However, to achieve antenna gain, a large antenna height necessitates a large support component 940, resulting in a still relatively large overall height for the router 900, which would appear obtrusive on a desktop.

[0075] Figure 3 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application.

[0076] Therefore, in the embodiments of this application, see Figure 3 The electronic device 10 may include a transparent area 11 and a non-transparent area 12, and the transparent area 11 and the non-transparent area 12 may be along the height direction of the electronic device 10 (e.g., Figure 3 Arranged in the Z-direction, when the electronic device 10 is placed on a table, the non-transparent area 12 can be located between the table and the transparent area 11. Because the transparent area 11 is transparent, users can see objects behind the electronic device 10 through at least a portion of it, reducing the area obstructed by the electronic device 10 and allowing it to blend more easily into its surroundings without appearing obtrusive. It is understandable that if the electronic device 10 is relatively tall, setting a larger height for the transparent area 11 and a smaller height for the non-transparent area 12 can also help the electronic device 10 blend better into its surroundings without appearing obtrusive.

[0077] It can be understood that transparent area 11 is an area with high transmittance, allowing light to pass through; for example, the transmittance of transparent area 11 can be 80%. Transmittance represents the ratio of the amount of light passing through the material layer to the total amount of light reaching the surface of the material layer. Higher transmittance indicates better light transmission of the material layer.

[0078] Understandably, the non-transparent area 12 means that the transmittance of this area is basically 0, and the user cannot see the items behind the electronic device 10 through the non-transparent area 12.

[0079] See also Figure 3The electronic device 10 may also include an antenna 100 and a motherboard 200. The motherboard 200 is located in the non-transparent area 12, and a portion of the antenna 100 is located in the transparent area 11 and another portion is located in the non-transparent area 12. The motherboard 200 is electrically connected to the antenna 100 and can act as a feed source, feeding power to the antenna 100 to excite the antenna 100 and enable it to transmit and receive radio frequency signals.

[0080] In some embodiments, the motherboard 200 may be provided with a radio frequency (RF) circuit (not shown in the figure), which is electrically connected to the antenna 100 and is used to feed power to the antenna 100.

[0081] Antenna 100 may include, but is not limited to, Wi-Fi antenna, cellular antenna, etc.

[0082] The number of antennas 100 can be one or more, for example, the number of antennas 100 can be three. When there are multiple antennas 100, at least two antennas 100 can operate in the same frequency band, or any two antennas 100 can operate at different frequencies. For example, multiple antennas 100 can include a first antenna and a second antenna, the first antenna can operate at a frequency of 2.4 GHz, and the second antenna can operate at a frequency of 5 GHz.

[0083] See also Figure 3 The antenna 100 may include a first line 160, a second line 170, a first electrical connector 140, a second electrical connector 150, and a feeding structure 110. Both the first electrical connector 140 and the second electrical connector 150 are electrically connected to the feeding structure 110, which is electrically connected to the motherboard 200. The motherboard 200 feeds power to the antenna 100 through the feeding structure 110. The feeding structure 110 is located in the non-transparent area 12, which reduces the area of ​​the feeding structure 110 obstructing the surrounding environment, allowing the electronic device 10 to blend better into its surroundings without appearing obtrusive.

[0084] It should be noted that, in addition to being part of the antenna 100, in some embodiments the power supply structure 110 and the antenna 100 can be two independent parts. In this case, the electronic device 10 may include an antenna assembly, which may include the antenna 100 and the power supply structure 110. The power supply structure 110 is configured to be electrically connected to the first electrical connector 140 and the second electrical connector 150 of the antenna 100.

[0085] See also Figure 3At least a portion of the power supply structure 110 is disposed in the non-transparent area 12. For example, a portion of the power supply structure 110 is disposed in the non-transparent area 12, and another portion is disposed in the transparent area 11. Of course, the power supply structure 110 may also be entirely located in the non-transparent area 12. It is understood that the larger the area of ​​the power supply structure 110 located in the non-transparent area 12, the smaller the area of ​​the power supply structure 110 that it obstructs from the surrounding environment, and the better the electronic device 10 integrates into the surrounding environment.

[0086] In some possible implementations, the feed structure 110 may include a coaxial line comprising an inner conductor and an outer conductor. One of the inner and outer conductors is electrically connected to a first electrical connector 140, and the other is electrically connected to a second electrical connector 150. For example, the inner conductor is electrically connected to the first electrical connector 140, and the outer conductor is electrically connected to the second electrical connector 150. This approach can reduce the cost of the antenna 100 while still meeting its operational requirements.

[0087] Of course, besides being constructed via coaxial lines, the power supply structure 110 can also be other structures in some embodiments. For example, the power supply structure 110 can be a microstrip line. Alternatively, in some embodiments, the power supply structure 110 can include a first connecting line and a second connecting line, with the first connecting line electrically connected to the first electrical connector 140 and the second connecting line electrically connected to the second electrical connector 150.

[0088] In some possible implementations, the power supply structure 110 can be electrically connected to the first electrical connector 140 and / or the second electrical connector 150 by welding, which can reduce the difficulty of electrically connecting the power supply structure 110 to the first electrical connector 140 and / or the second electrical connector 150.

[0089] See also the following for some possible implementations. Figure 3 At least a portion of the first electrical connector 140 is located in the non-transparent area 12, for example... Figure 3 As shown, the entire first electrical connector 140 is located in the non-transparent area 12. The larger the area of ​​the first electrical connector 140 in the non-transparent area 12, the less the first electrical connector 140 obstructs the surrounding environment, allowing the electronic device 10 to blend better into the surrounding environment without appearing obtrusive.

[0090] See also the following for some possible implementations. Figure 3The first electrical connector 140 may include solder pads. This allows the first electrical connector 140 to be manufactured using existing processes, reducing manufacturing difficulty and lowering the cost of the antenna 100. Alternatively, soldering can be used to electrically connect the first electrical connector 140 to the feed structure 110, further reducing the difficulty of connecting the feed structure 110 to the first electrical connector 140.

[0091] In some possible implementations, the first electrical connector 140 can be electrically connected to the opaque portion of the first line 160, which can reduce the difficulty of electrically connecting the first line 160 and the first electrical connector 140.

[0092] In some possible implementations, the second electrical connector 150 can be electrically connected to the opaque portion of the second line 170, which can reduce the difficulty of electrically connecting the second line 170 to the second electrical connector 150.

[0093] See also the following for some possible implementations. Figure 3 At least a portion of the second electrical connector 150 is located in the non-transparent area 12, for example... Figure 3 As shown, the entire second electrical connector 150 is located in the non-transparent area 12. The larger the area of ​​the second electrical connector 150 in the non-transparent area 12, the less the second electrical connector 150 obstructs the surrounding environment, allowing the electronic device 10 to blend better into the surrounding environment without appearing obtrusive.

[0094] See also the following for some possible implementations. Figure 3 The second electrical connector 150 may include solder pads. This allows the second electrical connector 150 to be manufactured using existing processes, reducing manufacturing difficulty and lowering the cost of the antenna 100. Alternatively, soldering can be used to electrically connect the second electrical connector 150 to the feed structure 110, further reducing the difficulty of connecting the feed structure 110 to the second electrical connector 150.

[0095] In the embodiments of this application, see Figure 4 The first line 160 and the second line 170 are spaced apart. The first line 160 is electrically connected to the first electrical connector 140 and is electrically connected to the power supply structure 110 through the first electrical connector 140. At least a portion of the first line 160 is located in the non-transparent area 12. For example, a portion of the first line 160 is located in the transparent area 11 and another portion is located in the non-transparent area 12.

[0096] In some examples, the first line 160 may include a radiator, thus at least a portion of the first line 160 may function as a radiator, and the first line 160 may radiate electromagnetic signals.

[0097] For example, see [link to previous article] Figure 3 The first line 160 may include a first part 161 and a second part 162. At least a portion of the first part 161 is located between the second part 162 and the second line 170. The first part 161 is electrically connected to the first electrical connector 140 and electrically connected to the second part 162. The second part 162 may be indirectly electrically connected to the first electrical connector 140 through the first part 161.

[0098] In some embodiments, the second portion 162 can serve as a radiator, and the first portion 161 can serve as an electrical connection structure connecting the radiator and the first electrical connector 140. Therefore, a portion of the first line 160 serves as a radiator. Of course, in addition to using the second portion 162 as a radiator, in some embodiments, both the first portion 161 and the second portion 162 can serve as radiators; thus, the entire first line 160 can serve as a radiator.

[0099] In some embodiments, see continue to see Figure 3 The first part 161 and the second part 162 can be an integral structure. Of course, in addition to being an integral structure, the first part 161 and the second part 162 can also be electrically connected by welding, electrical contact or other means.

[0100] It should be noted that the dividing position between the first part 161 and the second part 162, except as shown in the example... Figure 3 Besides the one shown, it can also be in other locations.

[0101] The foregoing description indicates that at least a portion of the first line 160 serves as a radiator. However, in other examples, the antenna 100 may also include a radiator coupled to the first line 160, with the first electrical connector 140 electrically connected to the radiator via the first line 160. Therefore, the first line 160 may not include a radiator, and the entire first line 160 can serve as an electrical connection structure electrically connecting the first electrical connector 140 and the radiator.

[0102] The radiator can be directly coupled to the first line 160, and the first line 160 can directly feed power to the radiator. Alternatively, the radiator can be indirectly coupled to the first line 160, and the first line 160 can couple power to the radiator.

[0103] In some examples, when the first line 160 is directly coupled to the radiator, the first line 160 and the radiator can be an integral structure.

[0104] In some embodiments, when the first line 160 does not have a radiator, the first line 160 can be... Figure 3The first part, 161, constitutes the structure, and correspondingly, the radiator can be accessed through... Figure 3 The second part, 162, constitutes the structure.

[0105] It should be noted that when the first line 160 includes a radiator, a portion of the first line 160 is located in the transparent area 11 and another portion is located in the non-transparent area 12. When the first line 160 does not include a radiator, at least a portion of the first line 160 is located in the non-transparent area 12. In this case, the first line 160 may be entirely located in the non-transparent area 12, or a portion of the first line 160 may be located in the transparent area 11 and another portion may be located in the non-transparent area 12.

[0106] In this embodiment, the specific structure of the radiator is not particularly limited. For example, the structure of the radiator can be as follows: Figure 3 The specific structure of the second part 162. Additionally, at least a portion of the radiator is disposed in the transparent region 11, for example, Figure 3 When the second part 162 serves as a radiator, the entire radiator is positioned within the transparent region 11. In practical implementation, by rationally designing the dimensions of the radiator, the mode of the antenna 100 can be set to a preset mode. For example, by setting the length of the radiator to be greater than or equal to one-eighth of the operating wavelength of the antenna 100 and less than or equal to one-half of the operating wavelength of the antenna 100, the electrical signal on the radiator is half a cycle of a sine wave, thus constructing a half-wave distribution that satisfies the requirements of the electronic device 10.

[0107] Figure 4 for Figure 3 A schematic diagram of point A in the middle.

[0108] See Figure 4 At least a portion of the second line 170 is located in the non-transparent area 12. For example, a portion of the second line 170 is located in the transparent area 11, and another portion is located in the non-transparent area 12. Of course, the second line 170 can also be entirely located in the non-transparent area 12. The second line 170 is electrically connected to the second electrical connector 150, and the second line 170 is electrically connected to the power supply structure 110 through the second electrical connector 150. Along the arrangement direction of the first electrical connector 140 and the second electrical connector 150 (e.g., along the arrangement direction of the first electrical connector 140 and the second electrical connector 150...) Figure 4 (in the Z direction), the maximum distance between the bottom end of the second line 170 and the bottom end of the second electrical connector 150 (e.g., in the Z direction). Figure 4 The wavelength of L1 is less than or equal to one-eighth of the operating wavelength of antenna 100.

[0109] The bottom end of the second line 170 refers to the end of the second line 170 that is furthest from the first line 160 along the arrangement direction of the first electrical connector 140 and the second electrical connector 150, or in other words, the end of the second line 170 that is closest to the first line 160. Figure 3One end of the motherboard 200. Additionally, the bottom end of the second line 170 can include multiple, for example... Figure 4 As shown, the bottom end of the second line 170 may include, but is not limited to, positions such as c1, c2, or c3.

[0110] The bottom end of the second electrical connector 150 refers to the end of the second electrical connector 150 furthest from the first electrical connector 140 along the arrangement direction of the first electrical connector 140 and the second electrical connector 150 (e.g., Figure 4 (at c4), or rather, near the second electrical connector 150. Figure 3 One end of the motherboard 200.

[0111] Since the second line 170 has multiple bottom end positions, there are multiple different distances between the bottom end of the second line 170 and the bottom end of the second electrical connector 150, for example... Figure 4 As shown, the distance between positions c1, c2, or c3 and c4. Additionally, from... Figure 4 It can be seen that the distance between position c1 and position c4 is the largest, and this distance is the maximum distance between the bottom end of the second line 170 and the bottom end of the second electrical connector 150.

[0112] In this embodiment of the application, see again. Figure 4 By maximizing the distance between the bottom end of the second line 170 and the bottom end of the second electrical connector 150 (e.g., Figure 4 If L1 is less than or equal to one-eighth of the operating wavelength of antenna 100, the distance between the second electrical connector 150 and the bottom of antenna 100 can be shortened. The bottom of antenna 100 can be understood as the end of antenna 100 closest to motherboard 200. This reduces the height requirement of the non-transparent area 12. While keeping the height of electronic device 10 constant, the height of the transparent area 11 can be increased while reducing the height of the non-transparent area 12. This helps increase the transparent area of ​​electronic device 10, further reducing the obstruction area of ​​the surrounding environment and allowing electronic device 10 to blend better into its surroundings without appearing obtrusive.

[0113] Furthermore, when current flows through both the first line 160 and the second line 170, the maximum distance between the bottom end of the second line 170 and the bottom end of the second electrical connector 150 (e.g.) Figure 4 If L1 is less than or equal to one-eighth of the operating wavelength of antenna 100, and the current direction of the first current on the first line 160 is opposite to the current direction of the second current on the second line 170 in the arrangement direction of the first electrical connector 140 and the second electrical connector 150, the radiation generated by the first line 160 and the second line 170 can cancel each other in the far field, thereby reducing the influence on the electromagnetic signal radiated by antenna 100 and improving the performance of antenna 100.

[0114] The direction of the first current can be understood as the direction of the current component of the first current in the arrangement direction of the first electrical connector 140 and the second electrical connector 150, or it can be understood as the direction of the entire first current being parallel to the arrangement direction of the first electrical connector 140 and the second electrical connector 150.

[0115] The direction of the second current can be understood as the direction of the current component of the second current in the arrangement direction of the first electrical connector 140 and the second electrical connector 150, or it can be understood as the direction of the entire second current being parallel to the arrangement direction of the first electrical connector 140 and the second electrical connector 150.

[0116] See also the following for some possible implementations. Figure 4 The minimum line width of the first line is 160 (e.g.) Figure 4 The maximum line width of the middle D1 and the second line 170 (e.g.) Figure 4 The ratio of D2) is greater than or equal to 1 and less than or equal to 2. This setting allows the impedance of the first line 160 and the impedance of the second line 170 to be controlled within a reasonable range, so that the magnitude of the first current and the magnitude of the second current are basically the same. As a result, the radiation generated by the first line 160 and the second line 170 can cancel each other out, which can reduce the impact on the electromagnetic signal radiated by the antenna 100.

[0117] See also the following for some possible implementations. Figure 4 The second line 170 is about the axis of symmetry (e.g.) Figure 4 The antenna 100 has a symmetrical structure (with the P-axis in the middle), and the axis of symmetry is parallel to the arrangement direction of the first electrical connector 140 and the second electrical connector 150. This configuration allows the antenna 100 to form an omnidirectional radiation pattern in the far field, thereby increasing the radiation range of the antenna 100 and improving the user experience of the electronic device 10.

[0118] It should be noted that, in addition to being a symmetrical structure about the axis of symmetry, in some embodiments, the second line 170 may not be a symmetrical structure. For example, the entire second line 170 may be located on the axis of symmetry (e.g., Figure 4 On the same side of the P-axis, or along a direction perpendicular to the arrangement direction of the first electrical connector 140 and the second electrical connector 150, the second line 170 is located on the axis of symmetry (e.g., the axis of P-axis). Figure 4 The lengths of the parts on both sides of the P-axis are different.

[0119] See also the following for some possible implementations. Figure 4The second line 170 can be a single integral structure. Alternatively, in some possible implementations, the second line 170 may include two spaced-apart line portions, each electrically connected to the second electrical connector 150.

[0120] See also the following for some possible implementations. Figure 4 The second line 170 may include a first strip segment 610, a second strip segment 620, a third strip segment 630, a fourth strip segment 640, a fifth strip segment 650, a sixth strip segment 660, and a seventh strip segment 670 connected in sequence. The second strip segment 620, the third strip segment 630, the fifth strip segment 650, and the sixth strip segment 660 are located on the same side of the fourth strip segment 640. The second strip segment 620, the third strip segment 630, the fourth strip segment 640, the fifth strip segment 650, and the sixth strip segment 660 are all located between the first strip segment 610 and the seventh strip segment 670. The first strip segment 610, the second strip segment 620, and the third strip segment 630 form a U-shaped structure. The fifth strip segment 650, the sixth strip segment 660, and the seventh strip segment 670 form a U-shaped structure. The fourth strip segment 640 is electrically connected to the second electrical connector 150. The first strip segment 610, the third strip segment 630, the fifth strip segment 650, and the seventh strip segment 670 are all parallel to the first line 160.

[0121] It should be noted that, in addition to the structure of the second line 170, Figure 4 Besides the structure shown, other structures are also possible; for example, it can be... Figure 4 The fifth strip segment 650, the sixth strip segment 660, and the seventh strip segment 670 can be removed. Alternatively, in some embodiments, they can be... Figure 4 Remove the first bar segment 610 and the seventh bar segment 670 from the text.

[0122] Alternatively, in some embodiments, the second line 170 may further include an eighth strip segment, a ninth strip segment, a tenth strip segment, and an eleventh strip segment. The two ends of the eighth strip segment are respectively connected to the ninth strip segment and the first strip segment 610. The eighth strip segment, the ninth strip segment, and the first strip segment 610 can form a U-shaped structure. The two ends of the tenth strip segment are respectively connected to the seventh strip segment 670 and the eleventh strip segment. The tenth strip segment, the eleventh strip segment, and the seventh strip segment 670 can form a U-shaped structure.

[0123] It should be noted that the specific structure of the second line 170 can be other than the structures described in the embodiments of this application, which will not be elaborated here.

[0124] In some possible implementations, at least a portion of the first line 160 may be parallel to the second line 170, for example... Figure 4As shown, the first line 160 is parallel to the third strip segment 630 and the fifth strip segment 650 of the second line 170. This further enhances the far-field cancellation effect of the radiation generated by the first line 160 and the radiation generated by the second line 170, helping to further reduce the influence of the second line 170 on the electromagnetic signal radiated by the antenna 100, thereby further improving the performance of the antenna 100.

[0125] In some possible implementations, on the portions where the first line 160 and the second line 170 are parallel to each other, the direction of the first current flow is opposite to the direction of the second current flow. See, for an example... Figure 4 The first line 160 is parallel to the third strip 630, and the direction of the second current on the third strip 630 is opposite to the direction of the first current on the first line 160. This arrangement allows the radiation generated by the first line 160 and the second line 170 to almost completely cancel each other out in the far field, which helps to further improve the performance of the antenna 100.

[0126] In some possible implementations, the radiator is at least partially transparent, for example, the radiator is entirely transparent. In this way, by making at least a portion of the portion of the radiator located in the transparent area 11 transparent, the user can see the objects behind the radiator through the transparent portion, which allows the antenna 100 to better integrate into the surrounding environment of the electronic device 10, and further allows the electronic device 10 to better integrate into the surrounding environment without appearing obtrusive.

[0127] When part of the radiator is located in the transparent area 11, the larger the transparent area of ​​the part of the radiator located in the transparent area 11, the smaller the radiator's obstruction of the area around the electronic device 10, and the better the electronic device 10 integrates into the surrounding environment.

[0128] In some embodiments, when the radiator is entirely transparent, the radiator may be entirely located in the transparent region 11, or a portion of the radiator may be located in the transparent region 11 and another portion in the non-transparent region 12.

[0129] In some embodiments, when a portion of the radiator is transparent and another portion is opaque, the radiator may be entirely located in the transparent region 11, or the transparent portion of the radiator may be located in the transparent region 11 and the opaque portion may be located in the non-transparent region 12, or a portion of the transparent portion of the radiator may be located in the transparent region 11 and the opaque portion and another portion of the transparent portion may both be located in the non-transparent region 12.

[0130] In some possible implementations, the radiator is at least partially a metallic mesh structure, for example... Figure 4As shown, when the second part 162 acts as a radiator, the entire radiator has a metal mesh structure. This allows for the fabrication of very fine first metal lines 710 using metal mesh circuitry, ensuring that the transmittance of the radiator formed by the intersection of multiple first metal lines 710 meets requirements, for example, achieving a transmittance of 85%, thus realizing transparency. Furthermore, the metal mesh circuitry allows for control of the resistance of the first metal lines 710 within a reasonable range, giving them good conductivity and improving the radiator's radiation efficiency.

[0131] In some embodiments, when the radiator is a metal mesh structure, the radiator may be entirely located in the transparent area 11, or a portion of the radiator may be located in the transparent area 11 and another portion in the non-transparent area 12.

[0132] In some embodiments, when one part of the radiator is a metal mesh structure and the other part is not a metal mesh structure, the radiator may be entirely located in the transparent area 11, or the transparent part of the radiator may be located in the transparent area 11 and the opaque part may be located in the non-transparent area 12, or a part of the transparent part of the radiator may be located in the transparent area 11 and the opaque part and another part of the transparent part may both be located in the non-transparent area 12.

[0133] See also the following for some possible implementations. Figure 4 Radiators (e.g.) Figure 4 162) may include multiple intersecting first metal lines 710, the linewidth of which can range from 3µm to 20µm. This arrangement results in very fine linewidths of the first metal lines 710, making them inconspicuous to the naked eye, thus ensuring the transmittance of the radiator meets requirements and achieving a transparent effect. Furthermore, setting the linewidth of the first metal lines 710 to 3µm ranges from 20µm, allowing for compatibility with existing processes and reducing manufacturing costs.

[0134] For example, the linewidth of the first metal line 710 may include, but is not limited to, 3µm, 5µm, 15µm, etc. It should be noted that, in addition to being between 3µm and 20µm, the linewidth of the first metal line 710 may also be less than 3µm or greater than 20µm.

[0135] The material of the first metal wire 710 may include, but is not limited to, copper, copper alloys, and other metallic materials. When the material of the first metal wire 710 is copper, the portion of the radiator that has a metal mesh structure can be called mesh copper or virtual copper, and the portion of the radiator that does not have a metal mesh structure can be called solid copper.

[0136] The preceding text described setting at least a portion of the radiator as a metallic mesh structure to make it at least partially transparent. However, in some possible implementations, the radiator can be made of a transparent metallic material, such as indium tin oxide (ITO) or indium zinc oxide (IZO). This configuration also allows the radiator to have transparent properties, enabling the user to see objects behind it.

[0137] It should be noted that while the material of the radiator is a transparent metallic material, at least part of the radiator can also be a metal mesh structure, or the entire radiator may not be a metal mesh structure.

[0138] In some possible implementations, the portion of the radiator located in the transparent region 11 is at least partially transparent, for example... Figure 4 As shown, when the second part 162 located in the transparent area 11 is used as the radiator, the entire radiator is located in the transparent area 11 and is transparent. Of course, when the entire radiator is transparent, it can also be partially transparent. By setting at least a portion of the part of the radiator located in the transparent area 11 to be transparent, the area of ​​the radiator obstructing the surrounding environment can be reduced, allowing the electronic device 10 to blend better into the surrounding environment without appearing obtrusive.

[0139] It should be noted that, in addition to being at least partially transparent, the portion of the radiator located in the transparent area 11 may also be opaque in some possible implementations. That is, the portion of the radiator located in the transparent area 11 is not a metal mesh structure or is not made of transparent metal material.

[0140] In some embodiments, when the portion of the radiator located in the transparent area 11 is opaque, the portion of the radiator located in the transparent area 11 can be patterned to make the shape of the radiator aesthetically pleasing and to allow the electronic device 10 to blend better into the surrounding environment without appearing obtrusive.

[0141] In some possible implementations, at least a portion of the feed structure 110 is transparent; for example, a portion of the feed structure 110 is transparent while another portion is opaque. When a portion of the feed structure 110 is located in the transparent region 11, by making at least a portion of the portion of the feed structure 110 that is in the transparent region 11 transparent, a user can see objects behind the transparent portion of the feed structure 110, enabling the antenna 100 to better integrate into the surrounding environment of the electronic device 10, and further enabling the electronic device 10 to better integrate into the surrounding environment without appearing obtrusive.

[0142] In some examples, when the first line 160 as a whole acts as a radiator, the first line 160 may be entirely transparent or opaque, or the first line 160 may be partially transparent and partially opaque.

[0143] In other examples, when a portion of the first line 160 functions as a radiator and another portion does not, for example, see... Figure 4 The first line 160 includes a first portion 161 and a second portion 162, with the second portion 162 serving as a radiator. At least a portion of the first portion 161 can be transparent, or the entire first portion 161 can be opaque. The scheme for making at least a portion of the first portion 161 transparent can refer to the scheme for making at least a portion of the radiator transparent described above, for example, making at least a portion of the first portion 161 a metal mesh structure or made of a transparent metal material.

[0144] In some embodiments, when a portion of the first line 160 serves as a radiator and another portion does not, the structure of the metal mesh structure of the radiator may be the same as or different from the structure of the metal mesh structure of the portion of the first line 160 that does not serve as a radiator.

[0145] In some other examples, when the first line 160 does not include a radiator, and the first line 160 and the radiator are two independent components, at least a portion of the first line 160 may be transparent, or the entire first line 160 may be opaque. The scheme for making at least a portion of the first line 160 transparent can refer to the scheme for making at least a portion of the radiator transparent described above, for example, making at least a portion of the first line 160 a metal mesh structure or made of a transparent metallic material.

[0146] In some possible implementations, the second line 170 is at least partially transparent, for example... Figure 4 The second line 170 has a transparent portion and an opaque portion. Thus, when a portion of the second line 170 is located in the transparent area 11, by setting at least a portion of the second line 170 located in the transparent area 11 to be transparent, the user can see the objects behind it through the transparent portion of the second line 170. This allows the antenna 100 to better integrate into the surrounding environment of the electronic device 10, and further allows the electronic device 10 to better integrate into the surrounding environment without appearing obtrusive.

[0147] When a portion of the second line 170 is located in the transparent area 11, the larger the transparent area of ​​the portion of the second line 170 located in the transparent area 11, the smaller the area of ​​the second line 170 that obstructs the surrounding environment of the electronic device 10, and the better the effect of the electronic device 10 integrating into the surrounding environment.

[0148] In some embodiments, when the second line 170 is entirely transparent, the second line 170 may be entirely located in the non-transparent area 12, or a portion of the second line 170 may be located in the transparent area 11 and another portion in the non-transparent area 12.

[0149] In other embodiments, when a portion of the second line 170 is transparent and another portion is opaque, the second line 170 may be entirely located in the non-transparent area 12, or the transparent portion of the second line 170 may be located in the transparent area 11 and the opaque portion may be located in the non-transparent area 12, or a portion of the transparent portion of the second line 170 may be located in the transparent area 11 and the opaque portion and another portion of the transparent portion may both be located in the non-transparent area 12.

[0150] It should be noted that, in addition to setting at least a portion of the second line 170 to be transparent, in some possible implementations, the entire second line 170 may also be opaque, in which case at least a portion of the second line 170 is located in the non-transparent area 12.

[0151] In some possible implementations, at least a portion of the second line 170 is a metal mesh structure, for example... Figure 4 As shown, part of the second line 170 is a metal mesh structure, and another part is not. By reasonably designing the line size of the metal mesh structure, the lines of the metal mesh structure are made inconspicuous, thereby achieving a transparent effect for at least a portion of the second line 170, and thus giving at least a portion of the second line 170 transparent characteristics.

[0152] In some embodiments, when the second line 170 is a metal mesh structure, the second line 170 may be entirely located in the non-transparent area 12, or a portion of the second line 170 may be located in the transparent area 11 and another portion in the non-transparent area 12.

[0153] In some embodiments, when a portion of the second line 170 is a metal mesh structure and another portion is not a metal mesh structure, a portion of the second line 170 is transparent and the other portion is opaque. In this case, the second line 170 may be entirely located in the non-transparent area 12, or the transparent portion of the second line 170 may be located in the transparent area 11 and the opaque portion may be located in the non-transparent area 12, or a portion of the transparent portion of the second line 170 may be located in the transparent area 11 and the opaque portion and another portion of the transparent portion may both be located in the non-transparent area 12.

[0154] See also the following for some possible implementations. Figure 4The second line 170 may include multiple intersecting second metal lines 720, with the linewidth of the second metal lines 720 ranging from 3µm to 20µm. This arrangement results in very fine linewidths of the second metal lines 720, making them inconspicuous to the naked eye, thus ensuring the transmittance of the metal mesh structure meets requirements and achieving a transparent effect. Furthermore, setting the linewidth of the second metal lines 720 to 3µm ranges from 20µm, allowing for compatibility with existing processes and reducing manufacturing costs.

[0155] For example, the linewidth of the second metal line 720 can be, but is not limited to, 3µm, 5µm, 15µm, etc. It should be noted that, in addition to being between 3µm and 20µm, the linewidth of the second metal line 720 can also be less than 3µm or greater than 20µm.

[0156] The material of the second metal wire 720 may include, but is not limited to, copper, copper alloys, and other metallic materials. When the material of the second metal wire 720 is copper, the portion of the second line 170 that has a metal mesh structure can be called mesh copper or virtual copper, and the portion of the second line 170 that does not have a metal mesh structure can be called solid copper.

[0157] The preceding text described setting at least a portion of the second line 170 as a metallic mesh structure to make at least a portion of the second line 170 transparent. However, in some possible implementations, the material of the second line 170 can be a transparent metallic material, such as indium tin oxide (ITO) or indium zinc oxide (IZO). This configuration also allows the second line 170 to have transparent properties, enabling the user to see the objects behind it.

[0158] It should be noted that when the first line 160 includes a radiator, and at least a portion of the first line 160 and at least a portion of the second line 170 are both metal mesh structures, the structure of the metal mesh structure of the first line 160 and the structure of the metal mesh structure of the second line 170 may be the same or different. Furthermore, when the first line 160 and the radiator are two independent components, the structures of at least two of the metal mesh structures in the first line 160, the radiator, and the second line 170 may be the same or different.

[0159] Figure 5 This is another schematic diagram of the metal mesh structure provided in the embodiments of this application.

[0160] As described above, a metal mesh structure can be constructed using multiple intersecting metal wires, for example... Figure 4The diagram shows a metal mesh structure composed of multiple first metal wires 710 and a metal mesh structure composed of multiple second metal wires 720. Of course, the metal mesh structure can also be other structures. For example, see... Figure 5 Metal mesh structures can also be constructed using square or scale-like lines.

[0161] Figure 6 This is a schematic diagram of another structure of the antenna 100 provided in an embodiment of this application. Figure 7 for Figure 6 A schematic diagram at point B in the middle.

[0162] In the preceding description, the first part 161 is a strip structure, and its two ends are electrically connected to the second part 162 and the first electrical connector 140, respectively. However, the first part 161 can also be other structures. For example, in combination with... Figure 6 and Figure 7 It can be seen that the first line 160 may include a first part 161 and a second part 162. The first part 161 may be a U-shaped structure. The open end of the first part 161 is electrically connected to the second part 162, and the closed end of the first part 161 is electrically connected to the first electrical connector 140.

[0163] In some embodiments, see continue to see Figure 6 The first line 160 may include a first sub-segment 510, a second sub-segment 520 and a third sub-segment 530 connected in sequence. The first sub-segment 510 and the third sub-segment 530 are located on the same side of the second sub-segment 520. The first sub-segment 510, the second sub-segment 520 and the third sub-segment 530 form a U-shaped structure. The middle part of the second sub-segment 520 is electrically connected to the first electrical connector 140. The two ends of the first sub-segment 510 and the two ends of the third sub-segment 530 are respectively electrically connected to the second part 162 and the first sub-segment 510.

[0164] In some embodiments, see continue to see Figure 6 The first sub-segment 510 has a portion with a metal mesh structure and a portion without, making one part of the first sub-segment 510 transparent and the other part opaque. The third sub-segment 530 also has a portion with a metal mesh structure and a portion without, making one part of the third sub-segment 530 transparent and the other part opaque. The second sub-segment 520 does not have a metal mesh structure and is therefore opaque.

[0165] Of course, the first line 160, in addition to... Figure 6Besides the structure shown, other structures are also possible. In some embodiments, the first sub-segment 510, the second sub-segment 520, and the third sub-segment 530 are not metal mesh structures, and the first line 160 is made of a transparent metal material. Alternatively, in some embodiments, the entire first sub-segment 510 and the entire second sub-segment 520 are metal mesh structures, while the third sub-segment 530 is not a metal mesh structure.

[0166] Figure 8 This is a schematic diagram of another structure of the antenna 100 provided in an embodiment of this application.

[0167] See also some possible implementations. Figure 8 The antenna 100 may also include a carrier 120, on which at least a portion of the radiator is disposed, for example... Figure 8 When the second part 162 serves as a radiator, the entire radiator is mounted on the support member 120. This allows the radiator to be fabricated on the support member 120 as a substrate during manufacturing. Furthermore, to prevent the support member 120 from affecting the radiator, the surface of the support member 120 in contact with the radiator is made of a non-metallic material. In some embodiments, the support member 120 may be made of an insulating material.

[0168] In some embodiments, see continue to see Figure 8 The first line 160 and the second line 170 can be disposed on the same surface of the carrier 120. The first electrical connector 140 is disposed on the side of the first line 160 away from the carrier 120, and the second electrical connector 150 is disposed on the side of the second line 170 away from the carrier 120. In this way, the carrier 120 can serve as a substrate for the antenna 100, and the antenna 100 can be fabricated on the substrate.

[0169] In some embodiments, see continue to see Figure 8 The support member 120 can be a flat plate structure. Of course, it can also be other structures, for example, the support member 120 can be a cylindrical structure or a block structure.

[0170] In some embodiments, at least a portion of the carrier 120 is transparent, and at least a portion of the radiator can be disposed on the transparent portion of the carrier 120. Thus, the carrier 120 has a transparent portion; for example, the transmittance of the transparent portion of the carrier 120 can be 80%. By disposing at least a portion of the transparent portion of the carrier 120 in the transparent area 11, the user can see objects behind the carrier 120 through the transparent portion, reducing the area of ​​the antenna 100 obstructing the surrounding environment and helping the electronic device 10 to better integrate into the surrounding environment without appearing obtrusive. Furthermore, by using the transparent portion of the carrier 120 to carry the radiator, the area of ​​the carrier 120 obstructing the surrounding environment can be reduced.

[0171] For example, the material of the carrier 120 may include, but is not limited to, transparent materials such as transparent polyimide (PI), colorless polyimide, cyclic olefin polymers, polyethylene terephthalate (PET), polycarbonate (PC), transparent acrylic, glass, and crystal.

[0172] In some embodiments, when a portion of the carrier 120 is transparent and another portion is opaque, the opaque portion of the carrier 120 can be disposed in the non-transparent area 12, and at least a portion of the second line 170 is disposed on the opaque portion of the carrier 120, which can reduce the area of ​​the antenna 100 obstructing the environment around the electronic device 10, allowing the electronic device 10 to better integrate into the surrounding environment.

[0173] Figure 9 This is a cross-sectional schematic diagram of another structure of the antenna 100 provided in an embodiment of this application.

[0174] See also some possible implementations. Figure 9 The antenna 100 may also include a transparent protective layer 130, which is fixedly connected to the carrier 120. The radiator is located between the carrier 120 and the transparent protective layer 130, for example... Figure 9 The second part 162, which serves as the radiator, is located between the transparent protective layer 130 and the carrier 120. In this way, the transparent protective layer 130, the radiator, and the carrier 120 can form a sandwich structure. The transparent protective layer 130 can protect the radiator, prevent damage to the radiator, and improve the reliability of the antenna 100.

[0175] See also Figure 9 The first line 160 and the second line 170 are both located between the carrier 120 and the transparent protective layer 130. In this way, the transparent protective layer 130 can cover the first line 160 and the second line 170 to protect them and improve the reliability of the antenna 100.

[0176] For example, the material of the transparent protective layer 130 may include, but is not limited to, transparent polyimide (PI), colorless polyimide, cyclic olefin polymer, polyethylene terephthalate (PET), polycarbonate (PC), transparent acrylic, glass, crystal, etc.

[0177] When the material of the carrier 120 is a transparent material such as PI or PET, the material of the transparent protective layer 130 may be the same as or different from the material of the carrier 120.

[0178] In some embodiments, the transparent protective layer 130 can be fixedly connected to the carrier 120 by adhesive bonding. For example, a light-transmitting colloid, such as an optically clear adhesive (OCA), can be provided between the transparent protective layer 130 and the carrier 120.

[0179] In some embodiments, the antenna 100 may further include a first through-hole and a second through-hole. The first through-hole penetrates the transparent protective layer 130, exposes a portion of the surface of the first line 160, and at least a portion of the first electrical connector 140 is located inside the first through-hole and electrically connected to the first line 160. The second through-hole penetrates the transparent protective layer 130, exposes a portion of the surface of the second line 170, and at least a portion of the second electrical connector 150 is located inside the second through-hole and electrically connected to the second line 170.

[0180] In some embodiments, when the transparent protective layer 130 is made of a material that is not heat-resistant, for example, when the transparent protective layer 130 is made of polyethylene terephthalate with a temperature resistance of less than 180°C, the power supply structure 110 can be welded to the first electrical connector 140 and the second electrical connector 150 by low-temperature welding to prevent the transparent protective layer 130 from being burned.

[0181] In some embodiments, the power supply structure can be welded to the first electrical connector 140 and the second electrical connector 150 using a low-temperature tin welding method. The main component of the flux is an alloy, which is mainly a tin-bismuth alloy.

[0182] Figure 10 This is another structural schematic diagram of the electronic device 10 provided in the embodiments of this application. Figure 11 for Figure 10 A cross-sectional view along the CC direction.

[0183] See also some possible implementations. Figure 10 The electronic device 10 may also include a housing 300, which may be cylindrical in shape. A portion of the housing 300 is located in a transparent area 11, and another portion is located in a non-transparent area 12. The portion of the housing 300 located in the transparent area 11 is transparent. See also Figure 11 Both the motherboard 200 and the antenna 100 are located inside the housing 300.

[0184] See also the following for some possible implementations. Figure 11 The antenna 100 is spaced apart from the inner wall of the housing 300, meaning that the antenna 100 is suspended inside the housing 300.

[0185] It should be noted that, in addition to the portion of the housing 300 located in the transparent area 11 being transparent, in some embodiments, the portion of the housing 300 located in the non-transparent area 12 may also be transparent. Therefore, the housing 300 may be entirely transparent, or a portion of the housing 300 may be transparent while another portion is opaque.

[0186] In some possible implementations, when the housing 300 is entirely transparent, in order to make the electronic device 10 have a transparent area 11 and a non-transparent area 12, the electronic device 10 may also include an opaque component, which is fixedly connected to the housing 300. The opaque component is used to partially overlap with the housing 300 to form the boundary range of the non-transparent area 12. The portion of the housing 300 that does not overlap with the opaque component can form the boundary range of the non-transparent area 12.

[0187] In some possible implementations, when a portion of the housing 300 is transparent and another portion is opaque, the range of the opaque portion of the housing 300 can be the boundary range of the non-transparent area 12, and the range of the transparent portion of the housing 300 can be the boundary range of the transparent area 11.

[0188] In some embodiments, the housing 300 may include a transparent outer shell and a non-transparent bottom shell. The transparent outer shell and the non-transparent bottom shell are fixedly connected. The transparent outer shell and the non-transparent bottom shell enclose a space for accommodating structures such as the motherboard 200 and the antenna 100. The area of ​​the transparent outer shell that does not contact the non-transparent bottom shell can form the boundary range of the transparent area 11, and the area of ​​the non-transparent bottom shell can form the boundary range of the non-transparent area 12.

[0189] The transparent outer shell and the non-transparent bottom shell can be fixedly connected by means of snap-fit, threaded connection, etc.

[0190] The previous text described the shell 300 as having a cylindrical shape, but it could also be other shapes. For example, the shell 300 could be a cube or a cuboid.

[0191] Figure 12 This is another structural schematic diagram of the electronic device 10 provided in the embodiments of this application.

[0192] Alternatively, in some possible implementations, see [link to relevant documentation]. Figure 12The housing 300 includes a non-transparent main body 310 and at least one transparent support portion 320. The internal space of the non-transparent main body 310 can be used to house the motherboard 200. There are four transparent support portions 320, although the number can be less or more than four. The four transparent support portions 320 are located on the same side of the non-transparent main body 310, and one end of each transparent support portion 320 can be movably connected to the non-transparent main body 310, allowing the angle between the transparent support portion 320 and the non-transparent main body 310 to be variable. Each transparent support portion 320 has at least a portion of at least one antenna 100 disposed inside it; for example, each transparent support portion 320 has at least one portion of an antenna 100 disposed inside it.

[0193] Figure 13 This is another structural schematic diagram of the electronic device 10 provided in the embodiments of this application.

[0194] Alternatively, in some possible implementations, see [link to relevant documentation]. Figure 13 The housing 300 may include a transparent sub-shell 340 and a non-transparent sub-shell 350, which are stacked together. The transparent sub-shell 340 may be fixedly connected to the non-transparent sub-shell 350. Along the height direction of the electronic device 10 (e.g.) Figure 13 (In the Z-direction), the height of the transparent sub-shell 340 is greater than the height of the non-transparent sub-shell 350 / 340, which allows the shell 300 to have a shape similar to an L-shaped plate structure. The non-transparent sub-shell 350 / 340 is used to house the motherboard 200 described above.

[0195] See also Figure 13 Since the non-transparent subshell 350340 is opaque, the area containing the non-transparent subshell 350340 can be considered the boundary of the non-transparent area 12. Meanwhile, the area containing the transparent subshell 340 that does not overlap with the non-transparent subshell 350340 can be considered the boundary of the transparent area 11.

[0196] See also Figure 13 At least a portion of the antenna 100 is disposed inside the transparent sub-shell 340, thereby allowing the antenna 100 to have a large height and improve its gain.

[0197] See also Figure 13 The number of antennas 100 is two, but of course, there can be more or fewer than two.

[0198] Figure 14 Another structure of the electronic device 10 provided in the embodiments of this application is along Figure 10 The diagram shows a cross-sectional view along the CC direction.

[0199] The preceding text described antenna 100 suspended inside housing 300; however, in some possible implementations, such as Figure 14 As shown, at least a portion of the antenna 100 can be attached to the inner wall of the housing 300. Since the inner wall of the housing 300 has a large area, attaching at least a portion of the antenna 100 to the inner wall of the housing 300 can make the size of the antenna 100 larger, which can increase the size of the radiator and help improve the gain of the antenna 100.

[0200] The number of antennas 100 attached to the inner wall of the housing 300 can be one or more.

[0201] See also Figure 14 The antenna 100 may include a transparent protective layer 130 and a carrier 120 stacked together, as well as a first line 160 and a second line 170 located between the transparent protective layer 130 and the carrier 120. The carrier 120 is fixedly connected to the inner wall of the housing 300.

[0202] It should be noted that when the antenna 100 is attached to the inner wall of the housing 300, the antenna 100 has a carrier 120 in addition to the carrier 120. In some possible implementations, the carrier 120 can be removed from the antenna 100, and the housing 300 can be reused as the carrier 120. Therefore, the antenna 100 can be directly made on the housing 300.

[0203] Figure 15 Another structure of the electronic device 10 provided in the embodiments of this application is along Figure 10 The diagram shows a cross-sectional view along the CC direction.

[0204] See also some possible implementations. Figure 15 The electronic device 10 may also include a transparent inner shell 400 located inside the housing 300. At least a portion of the transparent inner shell 400 is located in the transparent area 11; for example, the entire transparent inner shell 400 is located in the transparent area 11. At least a portion of the antenna 100 is disposed inside the transparent inner shell 400; for example, a portion of the antenna 100 is located inside the transparent inner shell 400, and another portion is located outside the transparent inner shell 400.

[0205] When the electronic device 10 has a transparent inner shell 400, the antenna 100 can be fixedly connected to the transparent inner shell 400, or the antenna 100 can be fixedly connected to the housing 300. The antenna 100 can be directly or indirectly fixedly connected to the transparent inner shell 400, or the antenna 100 can be directly or indirectly fixedly connected to the housing 300.

[0206] When the electronic device 10 has a transparent inner shell 400, the antenna 100 may have a carrier 120, or the antenna 100 may reuse the transparent inner shell 400 as the carrier 120 while removing the carrier 120.

[0207] Figure 16 for Figure 3 The diagram shows the current distribution of antenna 100. Figure 17 for Figure 3 The radiation energy pattern of antenna 100 shown.

[0208] In some possible implementations, when Figure 3 When the antenna 100 shown is used as a 5G antenna, the current distribution on the antenna 100 can be as follows: Figure 16 As shown, the currents on the radiator are in the same direction, and the current distribution is strongest at the center of the radiator. Also see... Figure 17 The antenna 100's radiation direction enables horizontal (e.g., parallel to the ground) coverage, with the central portion of the radiation pattern providing the largest coverage area. The antenna 100's omnidirectional gain can reach 6 dBi. Therefore, when the antenna 100 is used as a Wi-Fi antenna in a router, the signal radiated by the antenna 100 can effectively cover the indoor horizontal plane, thereby improving signal strength in various rooms.

[0209] In some possible implementations, when Figure 3 When the antenna 100 is used as a 2.4G antenna, the current in the antenna 100 is in the same direction. Furthermore, the radiation direction of the antenna 100 can achieve horizontal plane (e.g., parallel to the ground) coverage, with the central portion of the radiation pattern providing the largest coverage area to the ground. The omnidirectional gain of the antenna 100 can reach 4.5 dBi. Therefore, when the antenna 100 is used as a Wi-Fi antenna in a router, the signal radiated by the antenna 100 in the router can effectively cover the horizontal plane of the room, thereby improving the signal strength in various rooms.
