[0023] Implementation Methods of the Application

[0024] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0025] Please refer to Figure 1, which is a schematic diagram of the structure of an electronic device provided in an embodiment of the present application. The embodiment of the present application provides an electronic device 1, which has an antenna assembly 100. The antenna assembly 100 cooperates with a control system to achieve communication with the outside world, thereby improving the user experience of using the electronic device 1. For example, the electronic device 1 can be a display device such as a television, a computer, a mobile phone, or a household appliance such as an electronic door lock, an air conditioner, a refrigerator, or a washing machine. The embodiment of the present application is described using the electronic device 1 as an example of a television, and should not be understood as a limitation on the type of electronic device 1. For example, please refer to Figure 2 in conjunction with Figure 1, which is a schematic diagram of the exploded structure of the far-field voice assembly provided in an embodiment of the present application. The electronic device 1, such as a smart TV, may also include a far-field voice assembly 200 and a display screen 300. The far-field voice assembly 200 includes a housing 210, a far-field voice guide 220, a Bluetooth antenna 230, a plate 240, and a switch button 250. The far-field voice guide 220, Bluetooth antenna 230, and plate 240 are all located within the housing 210. The switch button 250 is located on the outer surface of the housing 210. The far-field voice guide 220 and Bluetooth antenna 230 are both located on the plate 240. The display screen 300 is used to display images for the user to view.

[0026] The antenna assembly 100 may also be integrated into the housing 210 and disposed on the plate 240 . For example, two antenna assemblies 100 may be disposed opposite to each other in a horizontal direction to improve the communication effect of the electronic device 1 .

[0027] In the RF field, antennas are manufactured from a variety of materials, including printed circuit boards, flexible circuit boards, and stainless steel. Designing antennas in a three-dimensional space often involves combining plastic components with flexible circuit boards, or using stainless steel. Common electronic devices, such as televisions, require antennas covering an increasing number of frequency bands, often necessitating the design of a multi-band antenna within a limited three-dimensional space. However, due to the multi-frequency nature of antennas, the required space often conflicts with the desired product form factor. Common antenna designs typically utilize a single feed. The advantage is that multi-band antennas can be connected to the chip via a single RF signal line, enabling multi-band transceiver functionality. However, the disadvantage is that, in a limited space, achieving multi-band coupling requires the use of a duplexer to combine the output signals, and multi-band coupling presents challenges, complicating antenna design. Typically, metal antennas utilize a dual-band single feed, but this often requires sufficient space and height for the antenna. However, existing dual-band antennas typically occupy a large space.

[0028] Because current products pursue thin, miniaturized, and integrated designs, electronic devices 1, such as televisions, typically integrate multiple interactive elements into a box below the display screen. From an appearance perspective, the box is required to be as thin and small as possible, which, to a certain extent, limits the design space for antennas. In the case of smart TVs, conventional antennas have poor radiation performance due to large metal structures such as the TV back panel. At the same time, the metal lower front frame structure also limits the aforementioned box to being assembled solely with metal. To address the antenna design issues of this type of structure, a metal planar inverted F-shape antenna (PIFA) is used. This effectively addresses the antenna radiation and directionality issues of large metal structures in smart TVs. However, to meet the requirements of multi-band metal PIFA antennas for WiFi bands, a certain radiation height is required. This height increases the thickness of the box, which does not meet the requirements for a thinner and lighter box.

[0029] Based on this, the embodiment of the present application improves the antenna assembly 100 to reduce the space occupied by the antenna assembly 100, thereby meeting the requirements of a lightweight and thin design of the box equipped with the antenna in the smart TV.

[0030] For example, referring to Figures 1 and 2 and Figure 3, Figure 3 is a schematic diagram of the structure of an antenna assembly provided in an embodiment of the present application. Antenna assembly 100 includes a substrate 110, a first-band radiator 120, a first feeder 130, a second-band radiator 140, and a second feeder 150.

[0031] The substrate 110 is also known as a printed circuit board (PCB). The substrate 110 is used to carry the structural components in the antenna assembly 100 and can realize electrical connections of the structural components in the antenna assembly 100 to achieve corresponding functions.

[0032] The first frequency band radiator 120 is used to radiate signals in the first frequency band. The first frequency band radiator 120 can be made of metal material, such as stainless steel, to achieve the corresponding radiation function. The first frequency band radiator 120 is arranged on the substrate 110. For example, the first frequency band radiator 120 can be protrudingly arranged on the substrate 110, that is, the first frequency band radiator 120 is a three-dimensional structure. For example, the first frequency band radiator 120 can be in the form of a sheet and can be bent into a required shape to form a three-dimensional structure. The first feeding element 130 is arranged on the substrate 110 and is electrically connected to the first frequency band radiator 120, so as to facilitate the transmission of radio frequency signals.

[0033] The second-band radiator 140 is disposed on the substrate 110 and spaced apart from the first-band radiator 120. For example, the second-band radiator 140 can be protruding from the substrate 110. The second-band radiator 140 can also be made of a metal material, such as stainless steel, and have a three-dimensional structure to facilitate its function. For example, the second-band radiator 140 can be in the form of a sheet and bendable into a desired shape to form a three-dimensional structure. The second-band radiator 140 is used to radiate signals in the second frequency band.

[0034] The second feeding element 150 is disposed on the substrate 110 and electrically connected to the second frequency band radiation element 140 . The second feeding element 150 is spaced apart from the first feeding element 130 .

[0035] It should be noted that the antenna assembly 100 of the embodiment of the present application is also the WiFi antenna in the smart TV. The second frequency band radiating element 140 and the first frequency band radiating element 120 radiate the second frequency band and the first frequency band respectively, that is, the antenna assembly 100 is a dual-band WiFi antenna type.

[0036] Exemplarily, the second frequency band is smaller than the first frequency band. For example, the second frequency band is a 2.4 GHz frequency band, and the first frequency band is a 5 GHz frequency band. These two frequency bands are also commonly used frequency bands.

[0037] It is understandable that the antenna assembly 100 of the embodiment of the present application has two feeding structures, which separate the feeding of the 2.4G band and the 5G band, replacing the existing dual-band single feeding method. There is no need to consider the structures of the two frequency bands and design them separately, which can reduce the cross-sectional height of the antenna to a certain extent. Experimental verification found that using the structure of the antenna assembly 100 of the embodiment of the present application, the height of the antenna of the embodiment of the present application is only 3.7 mm, and the thickness of the substrate 110 is 4.7 mm. In contrast, a typical single-feed dual-band metal antenna requires a height of 6 mm to 7 mm to not affect its radiation performance.

[0038] In the antenna assembly 100 provided in the embodiment of the present application, a first feeding element 130 and a second feeding element 150 are respectively provided for the first frequency band radiating element 120 and the second frequency band radiating element 140, that is, a dual-band dual feeding method is used to replace the existing dual-band single feeding method, and the setting of the duplexer is eliminated, so that the dual-frequency ranges are combined, and there is no need to consider the structures of the first frequency band and the second frequency band for separate design. Therefore, the overall height of the antenna assembly 100 can be reduced, thereby reducing the occupied space of the antenna assembly 100.

[0039] For example, please refer to Figures 1 to 3 and Figure 4, which is a schematic diagram of the first structural embodiment of the antenna assembly provided in an embodiment of the present application, excluding the substrate. The first-band radiator 120 includes a first welding plate 121, a first support plate 122, and a first main plate 123. The first welding plate 121 is attached to the substrate 110, and the first feeder 130 is connected to the first welding plate 121. The first support plate 122 is bent and connected to the first welding plate 121, extending away from the substrate 110. The first main plate 123 is bent and connected to the first support plate 122. The first welding plate 121, the first support plate 122, and the first main plate 123 enclose a first space 124, thereby forming a three-dimensional structure for the first-band radiator 120, which meets radiation requirements. The bent first main plate 123 also reduces the height of the first-band radiator 120 compared to a vertical arrangement.

[0040] It is understood that the first welding plate 121 is used to mount the first-band radiator 120 on the substrate 110 and is also the welding foot of the first-band radiator 120. The first support plate 122 and the first main plate 123 are components that form the three-dimensional shape of the first-band radiator 120. When manufacturing the first-band radiator 120, the first welding plate 121, the first support plate 122, and the first main plate 123 can be made from a single plate, which is then cut and positioned and bent to achieve an integrated formation of the first welding plate 121, the first support plate 122, and the first main plate 123. This can prevent the first-band radiator 120 from experiencing unstable radiation signals due to unstable connections and can reduce the overall height of the first-band radiator 120. Exemplarily, the antenna assembly 100 has a first direction X, a second direction Y, and a third direction Z that are perpendicular to each other. For the substrate 110 , the first direction X is the length direction of the substrate 110 , the second direction Y is the width direction of the substrate 110 , and the third direction Z corresponds to the thickness direction of the substrate 110 .

[0041] Among them, the first frequency band radiation element 120 and the second frequency band radiation element 140 are arranged along the first direction X, that is, the first frequency band radiation element 120 and the second frequency band radiation element 140 are arranged along the length direction of the substrate 110, so that the substrate 110 can be filled and space waste can be reduced.

[0042] For example, in the first direction X, the length of the first main plate 123 is greater than the length of the first support plate 122, and the length of the first support plate 122 is greater than the length of the first welding plate 121. In the second direction Y, the width of the first main plate 123 is greater than the width of the first welding plate 121. This is because the first main plate 123 is the main part for radiation. Therefore, setting the length and width of the first main plate 123 to be greater than the length and width of the other two plates can increase the radiation area and ensure the radiation effect. The first welding plate 121 serves as a welding foot and can be welded to the substrate 110. Setting the length and width of the first welding plate 121 to the minimum can save materials and reduce the area occupied by the first welding plate 121 on the substrate 110 to reduce the impact on the settings of other electrical components on the substrate 110. The first support plate 122 serves as a support member and also as a transition member between the large-sized first main plate 123 and the small-sized first welding plate 121. Therefore, the size of the first support plate 122 is set to be between the first welding plate 121 and the first main plate 123, which can save materials and achieve a smooth transition between the first welding plate 121 and the first main plate 123.

[0043] The first support plate 122 serves as a transition plate and can be of an irregular shape. For example, the first support plate 122 includes a first sub-plate 1220, a second sub-plate 1222, and a third sub-plate 1224, which are sequentially connected along the third direction Z. The first sub-plate 1220 is connected to the first welding plate 121 by a bend, the third sub-plate 1224 is connected to the first main plate 123 by a bend, and the second sub-plate 1222 is located between the first sub-plate 1220 and the third sub-plate 1224.

[0044] Illustratively, the first welding plate 121 is located at one end of the first main plate 123, close to the edge of the substrate 110. Specifically, the first welding plate 121 is located at the end of the first main plate 123 away from the second-band radiator 140. In the first direction X, away from the second-band radiator 140, one end of the second sub-plate 1222 is flush with the first sub-plate 1220 and the third sub-plate 1224, respectively. In the direction toward the second-band radiator 140, the other end of the second sub-plate 1222 protrudes from the first sub-plate 1220 and the third sub-plate 1224, respectively. In the first direction X, the length of the third sub-plate 1224 is greater than that of the first sub-plate 1220. In the third direction Z, the thickness of the third sub-plate 1224 is less than that of the first sub-plate 1220. Providing an irregular shape for the first support plate 122 can save material and reduce costs while maintaining a certain level of support.

[0045] Exemplarily, the second frequency band radiator 140 includes a second welding plate 141, a second support plate 142, and a second main plate 143. The second welding plate 141 is attached to the substrate 110 and is spaced apart from the first welding plate 121 to reduce interference between the two and provide space for the installation of the second main plate 143. The second feeder 150 is electrically connected to the second welding plate 141. The second support plate 142 is bent and connected to the second welding plate 141, and the second support plate 142 extends in a direction away from the substrate 110. The second support plate 142 is spaced apart from the first support plate 122, which can also reduce interference and interference problems. The second main plate 143 is bent and connected to the second support plate 142, and the second main plate 143 is spaced apart from the first main plate 123.

[0046] The second welding plate 141 is also the welding foot of the second-band radiator 140, and is used to mount the second-band radiator 140 on the substrate 110. The second support plate 142 and the second main plate 143 are three-dimensional components of the second-band radiator 140. When manufacturing the second-band radiator 140, the second welding plate 141, the second support plate 142, and the second main plate 143 can be made from a single plate, which is then cut and positioned and bent to achieve an integrated molding of the second welding plate 141, the second support plate 142, and the second main plate 143. This can prevent the second-band radiator 140 from experiencing unstable radiation signals due to unstable connections. In addition, the bent second main plate 143 can reduce the overall height of the second-band radiator 140 compared to a vertical arrangement.

[0047] It is understandable that the second-band radiator 140 is also a three-dimensional structure, which can not only meet the radiation requirements but also reduce the height of the second-band radiator 140. In addition, the height of the second-band radiator 140 is the same as or similar to the height of the first-band radiator 120. This is because the embodiment of the present application combines the dual-band range and configures two feeders for the dual-band. The two feeders can transmit the radiation signals of the two frequency bands respectively, without the need for a coupling design and the need for separate designs for the first and second frequency bands. As a result, the overall height of the antenna assembly 100 can be reduced, thereby reducing the space occupied by the antenna assembly 100.

[0048] Exemplarily, the projection of the first main plate 123 on the substrate 110 covers the projection of the second welding plate 141 on the substrate 110. That is to say, setting the second frequency band radiation element 140 close to the first frequency band radiation element 120 can reduce the space occupied by the antenna assembly 100 along the first direction X; it can also achieve coupling, etc., to facilitate signal integration.

[0049] The second feeding element 150 extends along the second direction Y, and the first feeding element 130 also extends along the second direction Y, so as to facilitate connection with the control end and facilitate signal transmission.

[0050] Since the second welding plate 141 is located below the first main plate 123 , but the second main plate 143 is spaced apart from the first main plate 123 , the shape of the second support plate 142 may also be a spliced ​​shape or an irregular shape.

[0051] Illustratively, the second support plate 142 includes a fourth sub-plate 1420 and a fifth sub-plate 1422 connected thereto. The fourth sub-plate 1420 is bent and connected to the second welding plate 141. The fourth sub-plate 1420 extends along the first direction X, and its length along the first direction X is greater than that of the second welding plate 141, thereby facilitating the connection between the second welding plate 141 and the second main body plate 143. The fifth sub-plate 1422 is bent and connected to the second main body plate 143. The fifth sub-plate 1422 extends along the third direction Z, thereby cooperating with the fourth sub-plate 1420 to achieve the connection between the second main body plate 143 and the second welding plate 141.

[0052] It should be noted that due to the large length dimension of the second main plate 143 along the first direction X, relying solely on the second support plate 142 would render the second main plate 143 unstable. The end of the second main plate 143 away from the first-band radiator 120 is suspended in the air and susceptible to shaking. Therefore, in this embodiment of the present application, two support plates are provided for the second-band radiator 140. For example, please refer to Figures 1 to 4 and Figure 5, which is a schematic diagram of a second structural embodiment of the antenna assembly provided in this embodiment of the present application without the substrate. The second-band radiator 140 also includes a third welding plate 144 and a third support plate 145. The third welding plate 144 is attached to the substrate 110 and serves as the second welding leg of the second-band radiator 140. The third welding plate 144 and the second welding plate 141 are arranged opposite each other at the ends of the second main plate 143 along the first direction X, thereby forming stable support points for the second main plate 143 and reducing the impact on the performance of the second main plate 143. The third support plate 145 is bent and connected to the third welding plate 144 and the second main plate 143 respectively. The third support plate 145 and the fifth sub-plate 1422 are relatively arranged at the two ends of the second main plate 143 along the first direction X, so as to cooperate with the third welding plate 144 and the second welding plate 141 respectively to form a stable support for the second main plate 143.

[0053] Among them, for example, in the second direction Y, the width of the third welding plate 144 is greater than the width of the second welding plate 141. Since the third welding plate 144 is located at the end of the second main plate 143 away from the first frequency band radiation element 120, the width of the third welding plate 144 can be set slightly wider, which can improve the welding stability without affecting the setting of other devices.

[0054] The antenna assembly 100 of the embodiment of the present application adopts a dual-feed method to implement a design scheme of one antenna with two feeds and two frequency bands, and feeds the RF signal to different welding pins of the antenna respectively, so as to realize radiation of two different frequency bands.

[0055] Exemplarily, the first-band radiator 120 and the second-band radiator 140 are integrally formed, so the two are close to each other and are connected; compared with the first-band radiator and the second-band radiator being set separately, the space occupied by the first-band radiator 120 and the second-band radiator 140 in the first direction X can be saved, further reducing the volume of the antenna assembly 100 and facilitating the setting of the antenna assembly 100 in an electronic device 1 such as a smart TV.

[0056] For example, referring to Figures 1 through 5 and Figure 6, Figure 6 illustrates a third structural schematic diagram of an antenna assembly according to an embodiment of the present application, excluding the substrate. Antenna assembly 100 further includes a connecting plate 160 that connects first and second main plates 123 and 143 to achieve an integrated arrangement of first-band radiating element 120 and second-band radiating element 140.

[0057] The connecting plate 160 includes a first sub-connecting plate 161, a second sub-connecting plate 162, and a third sub-connecting plate 163. The first sub-connecting plate 161 is bent and connected to the first main plate 123 and is disposed on the opposite side of the first support plate 122. That is, the first sub-connecting plate 161 and the first support plate 122 are disposed at opposite ends of the first main plate 123 along the second direction Y. The second sub-connecting plate 162 is bent and connected to the second main plate 143 and is disposed at opposite ends of the second support plate 142 along the second direction Y. The third sub-connecting plate 163 connects the first sub-connecting plate 161 and the second sub-connecting plate 162. This allows for a more rational layout of the first-band radiating element 120 and the second-band radiating element 140, reducing additional space.

[0058] It should be noted that to achieve connection within the antenna circuit, the antenna typically requires grounding. Exemplarily, the connecting plate 160 further includes a first grounding plate 164, a second grounding plate 165, and a third grounding plate 166, all of which are used for grounding. The first grounding plate 164 is bent and connected to the third sub-connecting plate 163 and attached to the substrate 110, extending toward the first welding plate 121. The second grounding plate 165 is bent and connected to the third sub-connecting plate 163 and attached to the substrate 110. The second grounding plate 165 extends in the same direction as the first grounding plate 164, and the second grounding plate 165 is spaced apart from the first grounding plate 164. The third grounding plate 166 is bent and connected to the third sub-connecting plate 163 and attached to the substrate 110. The third grounding plate 166 also extends in the same direction as the first grounding plate 164. The third ground plane 166 is spaced apart from the second ground plane 165, and the second ground plane 165 is located between the first ground plane 164 and the third ground plane 166. Using three ground planes, i.e., three ground solder pins, to connect the two frequency band radiators can also achieve a certain degree of isolation, so that the antennas of the two frequency bands do not interfere with each other.

[0059] In which, the first feeder 130 and the second feeder 150 extend to the edge of the substrate 110 along the second direction Y. In order not to affect the feeding of the first feeder 130 and the second feeder 150, the second feeder 150 is arranged between the second grounding plate 165 and the third grounding plate 166, and the first feeder 130 is arranged on the side of the first grounding plate 164 away from the second grounding plate 165.

[0060] The shapes of the first feeder 130 and the second feeder 150 can be such that the area of ​​the first feeder 130 near the first welding plate 121 is larger than the area of ​​the end away from the first welding plate 121. The area of ​​the second feeder 150 near the second welding plate 141 is larger than the area of ​​the end away from the second welding plate 141. This configuration of the feeder facilitates the extraction of the radiation signals from the first and second main plates 123 and 143 and facilitates the connection of the feeder to other components. The antenna assembly 100 of the embodiment of the present application uses a dual-feed method to implement a design scheme of one antenna, two feeds, and two frequency bands. It includes a 5G band radiator, a 2.4G band radiator, a 5G band solder pin, a 2.4G band solder pin, and a grounding solder pin shared by the three antennas. The RF signal is fed separately to different antenna solder pins to achieve radiation in two different frequency bands. When used, the grounding solder pin is used to connect the radiators of the two frequency bands while achieving a certain degree of isolation, so that the antennas of the two frequency bands do not interfere with each other.

[0061] The antenna assembly 100 of the embodiment of the present application has an overall size of 24mm × 4.2mm × 3.7mm, occupying a substrate 110 area of ​​only 24mm × 4.2mm. The overall cross-sectional height is only 3.7mm, significantly reducing the module's spatial height. Similarly, the antenna is designed as a rectangular parallelepiped structure, with only four sides of the hexahedron having metal structures, greatly simplifying the production process and facilitating production. Furthermore, the antenna has a sufficiently large planar structure above it, providing a suction area for the nozzle to pick up the component during SMT (Surface Mount Technology) assembly, resulting in extremely high patch production performance. For surface mounting requirements on circuit boards, all solder pins of the metal antenna meet the requirements of automated patch assembly. Due to the unique structure of metal antennas, it is difficult to achieve a multi-band solution similar to PCB antennas using coupled parasitic elements. Therefore, in general, a multi-band design for metal antennas requires a certain radiation height and space to achieve multiple branches and multiple bands. The embodiment of the present application utilizes the dual-band characteristics of the antenna and adopts a dual-feed method to achieve an integrated dual-band metal antenna design.

[0062] By using the antenna assembly 100 of the embodiment of the present application, the standing wave ratio of the antenna meets the usage requirements of the WiFi band, and the bandwidth of the 5G band is extremely wide, which meets the expanded use of the 6G band by WiFi6e / WiFi7.

[0063] Moreover, when the antenna is in a single module state, the omnidirectional vertical polarization gain meets the requirement of -10dB, and the omnidirectionality is good; in the context of electronic devices 1 such as smart TVs, the gain is improved and the omnidirectionality is better.

[0064] In the antenna assembly 100 and the electronic device 1 provided in the embodiment of the present application, a first feeding element 130 and a second feeding element 150 are respectively provided for the first frequency band radiating element 120 and the second frequency band radiating element 140, that is, a dual-band dual feeding method is used to replace the existing dual-band single feeding method, and the setting of the duplexer is eliminated, so that the dual-frequency ranges are combined, and there is no need to separately design the structures of the first frequency band and the second frequency band. As a result, the overall height of the antenna assembly 100 can be reduced, thereby reducing the occupied space of the antenna assembly 100.
