Abstract
Description
Technical Field
[0001] This application relates to the field of communication technology, and more particularly to an electronic device. Background Technology
[0002] With technological advancements, mobile phones and other electronic devices with communication capabilities are becoming increasingly widespread. These devices typically include a mid-frame. In related technologies, the mid-frame usually comprises a unibody mid-plate and a frame. In other words, the frame and the mid-plate are directly connected as a single unit. Because the area where the frame and mid-plate are connected is relatively large, the structure of the mid-frame in related technologies causes heat-generating components such as the motherboard in the electronic device to transfer heat to the frame through the mid-plate, resulting in a high temperature for the frame. When users hold the electronic device, they typically grip the frame, thus experiencing the radiating heat and a poor user experience. Summary of the Invention
[0003] In a first aspect, this application provides an electronic device, which includes a mid-frame assembly and an antenna assembly. The mid-frame assembly includes a mid-plate, a frame, and an insulating member. The frame surrounds the outer periphery of the mid-plate and is spaced apart from the mid-plate. The insulating member is used to connect the mid-plate and the frame.
[0004] The antenna assembly includes a first antenna, a second antenna, and an isolator. Both the first antenna and the second antenna support a first target frequency band. The first antenna includes a first radiator with a first ground terminal, which is electrically connected to the middle plate for grounding. The second antenna includes a second radiator and a first grounding component. The first grounding component is separate from the second radiator and the middle plate. The second radiator has a second ground terminal, which is spaced apart from the first ground terminal. The first grounding component is electrically connected to the second ground terminal to the middle plate for grounding. Both the first radiator and the second radiator are located on the frame. The isolator is located between the first ground terminal and the second ground terminal and is electrically connected to the middle plate for grounding.
[0005] In summary, the electronic device provided in this application includes an antenna assembly comprising a first antenna and a second antenna. Both the first and second antennas support a first target frequency band, thus the antenna assembly exhibits good performance in the first target frequency band. Furthermore, the second antenna includes a first grounding component, which is separately structured from the second radiator and the middle plate. The first grounding component is electrically connected to a second grounding terminal connected to the middle plate. This allows the second grounding terminal to be grounded, satisfying the grounding requirement of the second radiator. Additionally, heat from other components in the electronic device (such as the motherboard and other heat-generating devices) is less likely to dissipate to the frame, resulting in less or no burning sensation when the user holds the frame, leading to a better user experience. Further, an isolator is located between the first and second grounding terminals and is electrically connected to the middle plate for grounding. Therefore, the isolator isolates the first and second antennas, providing good isolation and thus enabling the antenna assembly to perform well in the first target frequency band.

Obviously, the embodiments described in this application are only a part of the embodiments, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments provided in this application without creative effort are within the protection scope of this application.
[0047] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.
[0048] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a particular order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0049] This application provides an electronic device 1. The electronic device 1 includes, but is not limited to, devices capable of transmitting and receiving electromagnetic wave signals such as mobile phones and tablet computers. In this application, a mobile phone is used as an example of the electronic device 1; other devices can be referred to the specific description in this application.
[0050] The electronic device 1 provided in the embodiments of this application will now be described in detail.
[0051] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , Figure 1 A perspective view of an electronic device provided according to an embodiment of this application; Figure 2 for Figure 1 A front view of a portion of the structure of the electronic device provided in the document; Figure 3 for Figure 1 A rear-view equivalent schematic diagram of a portion of the structure of the electronic device provided in the document; Figure 4 for Figure 2 The equivalent circuit diagram of the electronic device provided in the document; Figure 5 for Figure 2 The diagram shows detailed identification of the electronic device. It should be noted that... Figure 3 The simplified schematic diagram of the frame 120 in the electronic device 1 is provided. In one embodiment, the electronic device 1 includes a mid-frame assembly 10, a screen 50, and a back cover 70. The screen 50 is disposed on one side of the mid-frame assembly 10, and the back cover 70 is disposed on the other side of the mid-frame assembly 10, with the back cover 70 facing away from the mid-frame. The front view of the electronic device 1 is a schematic diagram viewed from the direction of the screen 50 towards the back cover 70; the rear view of the electronic device 1 is a schematic diagram viewed from the direction of the back cover 70 towards the screen 50. The electronic device 1 provided in this application does not limit whether the electronic device 1 includes a screen 50 and a back cover 70.
[0052] In this embodiment, the electronic device 1 includes a mid-frame assembly 10 and an antenna assembly 30. The mid-frame assembly 10 includes a mid-plate 110, a frame 120, and an insulating member 130. The frame 120 surrounds the outer periphery of the mid-plate 110 and is spaced apart from the mid-plate 110. The insulating member 130 connects the mid-plate 110 and the frame 120. The antenna assembly 30 includes a first antenna 310, a second antenna 320, and an isolator 420. Both the first antenna 310 and the second antenna 320 support a first target frequency band. The first antenna 310 includes a first radiator 311. The first radiator 311 has a first ground terminal 3112, which is electrically connected to the mid-plate 110 for grounding. The second antenna 320 includes a second radiator 321 and a first grounding member 322. The first grounding member 322 is a separate structure from both the second radiator 321 and the mid-plate 110. The second radiator 321 has a second grounding terminal 3212. The second grounding terminal 3212 is spaced apart from the first grounding terminal 3112. The first grounding member 322 is electrically connected to the second grounding terminal 3212 to the middle plate 110 for grounding. Both the first radiator 311 and the second radiator 321 are located on the frame 120. The isolator 420 is located between the first grounding terminal 3112 and the second grounding terminal 3212 and is electrically connected to the middle plate 110 for grounding.
[0053] The middle plate 110 has a rectangular or similar rectangular plate structure. The material of the middle plate 110 can be aluminum alloy or aluminum. The middle plate 110 can serve as a ground electrode. The middle frame can be formed by die casting or stamping. Forming the middle plate 110 by die casting or stamping results in lower cost.
[0054] The frame 120 surrounds the outer periphery of the middle plate 110, and the frame 120 and the middle plate 110 are spaced apart; therefore, the frame 120 and the middle plate 110 are separate structures. The surface of the frame 120 facing away from the middle plate 110 constitutes at least a portion of the exterior surface of the electronic device 1. The frame 120 can be made of aluminum alloy or aluminum. The frame 120 can be machined using a Computer Numerical Control (CNC) milling machine. Because the frame 120 is machined using CNC, it has a better appearance and facilitates the formation of antenna radiators on the frame 120.
[0055] The frame 120 is a ring-shaped structure, such as a rectangular ring-shaped structure with rounded corners around the edges. It is understood that the shape of the frame 120 can be designed according to the specific structure of the electronic device 1, and this application does not impose any specific limitations.
[0056] The insulating component 130 is used to connect the middle plate 110 and the frame 120, so that the middle plate 110, the frame 120 and the insulating component 130 are connected together. The insulating component 130 is an insulating material. Optionally, the material of the insulating component 130 can be, but is not limited to, plastic.
[0057] Both the first antenna 310 and the second antenna 320 support the first target frequency band. When one of the first antenna 310 and the second antenna 320 is blocked and the communication performance is poor, the electronic device 1 can still use the other of the first antenna 310 and the second antenna 320 to communicate. Therefore, the antenna assembly 30 has good performance in the first target frequency band.
[0058] The first antenna 310 includes a first radiator 311, which is located on the frame 120. That is, the first radiator 311 is formed on the frame 120, or in other words, the frame 120 includes the first radiator 311.
[0059] Please refer to further information. Figure 5The first grounding terminal 3112 of the first radiator 311 is electrically connected to the middle plate 110 for grounding. In this embodiment, the first grounding terminal 3112 of the first radiator 311 and the middle plate 110 can be connected by riveting. In other embodiments, the first antenna 310 further includes a first connector 312, which is electrically connected to the first grounding terminal 3112 of the first radiator 311 and the middle plate 110 to ground the first grounding terminal 3112. In other words, the first antenna 310 includes a first connector 312, which is a separate structure from both the first radiator 311 and the middle plate 110, and the first connector 312 is electrically connected to the first grounding terminal 3112 to the middle plate 110 to ground the first grounding terminal 3112. The first connector 312 is a separate structure from both the first radiator 311 and the middle plate 110. This means that the first connector 312 is not part of the structure of the first radiator 311, nor is it part of the structure of the middle plate 110. The first connector 312 can be, but is not limited to, a weldable conductive component 3221 (e.g., a weldable steel sheet) or a conductive spring 3222. When the first connector 312 is a weldable conductive component 3221, a portion of the first connector 312 is welded to the first grounding terminal 3112, and the other portion is welded to the middle plate 110.
[0060] When the first antenna 310 includes a first connector 312, the first connector 312 is a separate structure from the first radiator 311 and the middle plate 110, and the first connector 312 is electrically connected to the first grounding terminal 3112 to the middle plate 110, on the one hand, the first grounding terminal 3112 can be grounded to meet the grounding requirement of the first radiator 311; on the other hand, the heat of other components (such as motherboard and other heat-generating devices) in the electronic device 1 is not easily dissipated to the frame 120, so that when the user holds the frame 120, there is less or no hot feeling, resulting in a better user experience.
[0061] Understandably, the first radiator 311 also has a first feed point P1. Accordingly, the first antenna 310 further includes a first feed source S1, which is electrically connected to the first feed point P1 to excite the first radiator 311 to operate in the first target frequency band.
[0062] The second antenna 320 includes a second radiator 321, which is located on the frame 120. That is, the second radiator 321 is formed on the frame 120, or in other words, the frame 120 includes the second radiator 321.
[0063] In this embodiment, the second antenna 320 includes a first grounding component 322. The first grounding component 322 is a separate structure from both the second radiator 321 and the middle plate 110. The first grounding component 322 is electrically connected to the second grounding terminal 3212 connected to the middle plate 110 to ground the second grounding terminal 3212. The fact that the first grounding component 322 is a separate structure from both the second radiator 321 and the middle plate 110 means that the first grounding component 322 is not part of the structure of the second radiator 321, nor is it part of the structure of the middle plate 110. The specific structural form of the first grounding component 322 will be described in detail later.
[0064] The second antenna 320 includes a first grounding component 322. The first grounding component 322 is a separate structure from the second radiator 321 and the middle plate 110. The first grounding component 322 is electrically connected to the second grounding terminal 3212 to the middle plate 110. On the one hand, the second grounding terminal 3212 can be grounded to meet the grounding requirements of the second radiator 321. On the other hand, the heat from other components in the electronic device 1 (such as the motherboard and other heat-generating devices) is not easily dissipated to the frame 120, so that when the user holds the frame 120, there is less or no hot feeling, resulting in a better user experience.
[0065] Understandably, the second radiator 321 also has a second feed point P2. Accordingly, the second antenna 320 further includes a second feed source S2, which is electrically connected to the second feed point P2 to excite the second radiator 321 to operate in the first target frequency band.
[0066] In this embodiment, the isolation member 420 includes a first isolation portion 421 and a second isolation portion 422. The first isolation portion 421 is connected to the middle plate 110. For example, the first isolation portion 421 can be an integral structure with the middle plate 110 or a separate structure. The first radiator 311 and the second radiator 321 are both located on the frame 120, and the first grounding terminal 3112 of the first radiator 311 and the second grounding terminal 3212 of the second radiator 321 are connected through a portion of the frame 120. For ease of description, the portion of the frame 120 connecting the first grounding terminal 3112 and the second grounding terminal 3212 is named the connecting portion 120c. In other words, the first radiator 311, the connecting portion 120c, and the second radiator 321 are connected and form an integral structure. The second isolation portion 422 is connected to the connecting portion 120c. For example, the second isolation portion 422 can be an integral structure with the connecting portion 120c or a separate structure. The second isolation part 422 is connected to the first isolation part 421, for example, by means of a tenon and mortise structure, so that the isolation member 420 is electrically connected to the middle plate 110.
[0067] In other embodiments, the isolation element 420 may be a separate structure for the first radiator 311, the second radiator 321, and the middle plate 110.
[0068] The isolator 420 is located between the first grounding terminal 3112 and the second grounding terminal 3212, and the isolator 420 is electrically connected to the middle plate 110 for grounding. Therefore, the isolator 420 can isolate the first antenna 310 and the second antenna 320, so that the first antenna 310 and the second antenna 320 have good isolation, thereby enabling the antenna assembly 30 to have good performance when operating in the first target frequency band.
[0069] In summary, the electronic device 1 provided in this application embodiment includes an antenna assembly 30 comprising a first antenna 310 and a second antenna 320. Both the first antenna 310 and the second antenna 320 support a first target frequency band, thus the antenna assembly 30 exhibits good performance in the first target frequency band. Furthermore, the second antenna 320 includes a first grounding component 322, which is separately structured from the second radiator 321 and the middle plate 110. The first grounding component 322 is electrically connected to the second grounding terminal 3212 to the middle plate 110. On one hand, this grounds the second grounding terminal 3212, satisfying the grounding requirement of the second radiator 321. On the other hand, heat from other components in the electronic device 1 (such as the motherboard and other heat-generating devices) is less likely to dissipate to the frame 120, resulting in less or no burning sensation when the user holds the frame 120, leading to a better user experience. Further, the isolator 420 is located between the first grounding terminal 3112 and the second grounding terminal 3212, and the isolator 420 is electrically connected to the middle plate 110 for grounding. Therefore, the isolator 420 can isolate the first antenna 310 and the second antenna 320, so that the first antenna 310 and the second antenna 320 have good isolation, thereby enabling the antenna assembly 30 to have good performance when operating in the first target frequency band.
[0070] The form of the first grounding element 322 will be described in detail below. Please refer to [link / reference needed]. Figure 6 and Figure 7 , Figure 6 A schematic diagram of the structure of a first grounding element provided in one embodiment; Figure 7 A schematic diagram of a grounding component provided for another embodiment. The first grounding component 322 includes a solderable conductive component 3221 or a conductive spring 3222. The first grounding component 322 is partially electrically connected to the second grounding terminal 3212, and the first grounding component 322 is partially electrically connected to the middle plate 110.
[0071] The weldable conductive component 3221 can be, but is not limited to, a weldable steel sheet. When the first grounding component 322 is a weldable conductive component 3221 (see...), Figure 6 A portion of the weldable conductive component 3221 is electrically connected to the second grounding terminal 3212 via solder joints, and another portion of the weldable conductive component 3221 is electrically connected to the middle plate 110 via additional solder joints. When the first grounding component 322 includes a conductive spring 3222 (see...), Figure 7 The conductive spring 3222 can be detachably connected to the second grounding terminal 3212 of the second radiator 321 and the middle plate 110.
[0072] The first grounding component 322 provided in this embodiment includes a solderable conductive component 3221 or a conductive spring 3222. On the one hand, it can ground the second grounding terminal 3212 to meet the grounding requirements of the second radiator 321. On the other hand, the heat from other components (such as the motherboard and other heat-generating devices) in the electronic device 1 is not easily dissipated to the frame 120, so that when the user holds the frame 120, there is less or no burning sensation, resulting in a better user experience.
[0073] Further, please refer to Figure 5 The first target frequency band includes a low-frequency band (LB). The frame 120 includes a bent and connected bottom frame 121 and a first side frame 122. The length of the first side frame 122 is greater than the length of the bottom frame 121. The first radiator 311 also has a first free end 3111 located on the bottom frame 121, and a first ground end 3112 located on the first side frame 122. The second radiator 321 is located on the first side frame 122, and the second radiator 321 also has a second free end 3211, which is located away from the first radiator 311 relative to the second ground end 3212.
[0074] The bottom border 121 is the short side of the electronic device 1, and the first side border 122 is the long side of the electronic device 1. When the electronic device 1 is in portrait mode, the bottom border 121 is located at the bottom of the electronic device 1. Figure 5 From a viewing angle, when the electronic device 1 is in portrait mode, the first side frame 122 is the side frame 120 of the electronic device 1. Figure 5 From a viewing angle, the first side frame 122 is located on the left side of the electronic device 1. It can be understood that in other embodiments, the first side frame 122 may also be located on the right side of the electronic device 1.
[0075] Both the first antenna 310 and the second antenna 320 support the first target frequency band, which includes a low-frequency band. Therefore, the first radiator 311 of the first antenna 310 and the second radiator 321 of the second antenna 320 are relatively long. The first free end 3111 of the first radiator 311 is located on the bottom frame 121, and the first ground end 3112 is located on the first side frame 122. The second radiator 321 is located on the first side frame 122. Therefore, both the first radiator 311 and the second radiator 321 can make full use of the size of the first side frame 122, making it easier to construct the first radiator 311 and the second radiator 321.
[0076] Please refer to the following: Figure 5 and Figure 8 , Figure 8 for Figure 5 The diagram illustrates the distance between the gap in the electronic device and the bottom frame. The first side frame 122 has a gap 321a defining the second free end 3211, and the distance d1 between the gap 321a and the bottom frame 121 satisfies: 90mm ≤ d1.
[0077] The gap 321a of the first side frame 122 is also called a seam, and the first side frame 122 has the gap 321a to form the second free end 3211. The distance d1 between the gap 321a and the bottom frame 121 satisfies: 90mm≤d1.
[0078] In one embodiment, the upper limit of the distance d1 between the gap 321a and the bottom frame 121 is not limited. In another embodiment, the distance d1 can satisfy: 90mm ≤ d1 ≤ 130mm. For example, the distance d1 can be, but is not limited to, 90mm, 95mm, 100mm, 105mm, 110mm, 115mm, 120mm, 125mm, or 130mm.
[0079] The first side frame 122 has a gap 321a that defines the second free end 3211. The distance d1 between the gap 321a and the bottom frame 121 satisfies: 90mm≤d1. On the one hand, this makes it less likely for the user to block the gap when the electronic device 1 is held in portrait mode, reducing or even avoiding the performance degradation of the second antenna 320 caused by the gap being blocked. On the other hand, when the electronic device 1 is held by the user in portrait mode, the user's hand can hold the second radiator 321. The user's hand has an amplifying effect on the first target frequency band supported by the second radiator 321, making the radiation efficiency of the second antenna 320 higher when supporting the first target frequency band.
[0080] Please see Figure 9 , Figure 10 and Figure 11 , Figure 9 A front view of a portion of the structure of an electronic device provided in another embodiment of this application; Figure 10 for Figure 9 A rear-view equivalent schematic diagram of a portion of the structure of an electronic device in the diagram; Figure 11 (a) and (b) are schematic diagrams of the circuit structures of the third and fourth antennas, respectively. The frame 120 also includes a top frame 123 and a second side frame 124, wherein the length of the second side frame 124 is greater than the length of the top frame 123. The top frame 123 is bent and connected to the first side frame 122, and is positioned opposite to the bottom frame 121. The second side frame 124 is bent and connected to both the top frame 123 and the bottom frame 121, and is positioned opposite to the first side frame 122. The antenna assembly 30 also includes a third antenna 330 and a fourth antenna 340. Both the third antenna 330 and the fourth antenna 340 support a second target frequency band, the frequency of which is greater than the frequency of the first target frequency band. The third antenna 330 includes a third radiator 331, a portion of which is located at the end of the first side frame 122 away from the bottom frame 121, and the other portion of which is located on the top frame 123. The fourth antenna 340 includes a fourth radiator 341, which is located on the second side frame 124.
[0081] The top border 123 is the short side of the electronic device 1, and the second side border 124 is the long side of the electronic device 1. When the electronic device 1 is in portrait mode, the top border 123 is located at the top of the electronic device 1. From the illustrated perspective, when the electronic device 1 is in portrait mode, the second side border 124 is the side border 120 of the electronic device 1. Figure 9From a certain perspective, the second side frame 124 is located on the right side of the electronic device 1.
[0082] In one embodiment, the second target frequency band may include the Middle High Band (MHB).
[0083] Both the third antenna 330 and the fourth antenna 340 support the second target frequency band. When one of the third antenna 330 and the fourth antenna 340 is blocked and the communication performance is poor, the electronic device 1 can still use the other of the third antenna 330 and the fourth antenna 340 to support the second target frequency band. Therefore, the antenna assembly 30 has good performance in the second target frequency band.
[0084] A portion of the third radiator 331 is located at one end of the first side frame 122 away from the bottom frame 121, and the other portion of the third radiator 331 is located on the top frame 123. Therefore, the third radiator 331 is disposed on the upper half of the electronic device 1. Figure 9 From the perspective of the electronic device 1, the third radiator 331 is located at the upper left corner. Figure 10 From a certain perspective, the third radiator 331 is located at the upper right corner of the electronic device 1, which can reduce or even avoid the influence of the human body on the third antenna 330 when transmitting and receiving the second target frequency band.
[0085] In one embodiment, the fourth radiator 341 is disposed on the second side frame 124 and located in the upper half of the second side frame 124 adjacent to the top frame 123. Thus, the fourth radiator 341 is disposed in the upper half of the electronic device 1, thereby reducing or even eliminating the influence of the human body on the fourth antenna 340 when transmitting or receiving the second target frequency band.
[0086] In this embodiment, a portion of the third radiator 331 is located at one end of the first side frame 122 away from the bottom frame 121, and the other portion of the third radiator 331 is located on the top frame 123; the fourth radiator 341 is located on the second side frame 124. Therefore, the third radiator 331 and the fourth radiator 341 are relatively far apart, thus reducing or even avoiding the probability that the third radiator 331 and the fourth radiator 341 are simultaneously blocked.
[0087] Understandably, in one embodiment, the third radiator 331 has a third feed point P3. Accordingly, the third antenna 330 further includes a third feed source S3 electrically connected to the third feed point P3 to excite the third radiator 331 to operate in the second target frequency band.
[0088] Understandably, in one embodiment, the fourth radiator 341 has a fourth feed point P4. Accordingly, the fourth antenna 340 further includes a fourth feed source S4 electrically connected to the fourth feed point P4 to excite the fourth radiator 341 to operate in the second target frequency band.
[0089] The third radiator 331 includes a free end and a ground end. The free end of the third radiator 331 is located on the top frame 123, and the ground end of the third radiator 331 is located on the first side frame 122. The third antenna 330 also includes two second grounding components 332. The second grounding components 332 are separate from the third radiator 331 and the middle plate 110, respectively. The two second grounding components 332 are spaced apart and electrically connected to the ground end of the third radiator 331 to the middle plate 110 for grounding.
[0090] In this embodiment, the third radiator 331 includes a free end and a ground end. For ease of description, the free end of the third radiator 331 is named the third free end 3311, and the ground end of the third radiator 331 is named the third ground end 3312. The third free end 3311 is located on the top frame 123, and the third ground end 3312 is located on the end of the first side frame 122 opposite to the bottom frame 121.
[0091] In this embodiment, the third grounding terminal 3312 has two grounding points G3, which are spaced apart. The grounding points G3 are electrically connected to the second grounding component 332, and different grounding points G3 are electrically connected to different second grounding components 332.
[0092] In this embodiment, the third antenna 330 includes a second grounding component 332. The second grounding component 332 is a separate structure from both the third radiator 331 and the middle plate 110. The second grounding component 332 is electrically connected to the third grounding terminal 3312 to the middle plate 110 to ground the third grounding terminal 3312. The fact that the second grounding component 332 is a separate structure from both the third radiator 331 and the middle plate 110 means that the second grounding component 332 is not part of the structure of the third radiator 331, nor is it part of the structure of the middle plate 110. The specific structural form of the second grounding component 332 will be described in detail later.
[0093] The second grounding component 332 includes a weldable conductive component 3221 or a conductive spring 3222. The second grounding component 332 is partially electrically connected to the third grounding terminal 3312 and partially electrically connected to the middle plate 110.
[0094] The weldable conductive component 3221 can be, but is not limited to, a weldable steel sheet. When the second grounding component 332 is a weldable conductive component 3221, a portion of the weldable conductive component 3221 is electrically connected to the third grounding terminal 3312 via solder joints, and the remaining portion of the weldable conductive component 3221 is electrically connected to the middle plate 110 via other solder joints. When the second grounding component 332 includes a conductive spring 3222, the conductive spring 3222 can be detachably connected to the third grounding terminal 3312 of the second radiator 321 and the middle plate 110.
[0095] The second grounding component 332 provided in this application includes a weldable conductive component 3221 or a conductive spring 3222. On the one hand, it can ground the third grounding terminal 3312 to meet the grounding requirements of the second radiator 321. On the other hand, the heat from other components (such as the motherboard and other heat-generating devices) in the electronic device 1 is not easily dissipated to the frame 120, so that when the user holds the frame 120, there is less or no burning sensation, resulting in a better user experience.
[0096] The third antenna 330 includes a second grounding component 332, which is a separate structure from the third radiator 331 and the middle plate 110. The second grounding component 332 is electrically connected to the third grounding terminal 3312 to the middle plate 110. On the one hand, the third grounding terminal 3312 can be grounded to meet the grounding requirements of the third radiator 331. On the other hand, the heat from other components in the electronic device 1 (such as the motherboard and other heat-generating devices) is not easily dissipated to the frame 120, so that when the user holds the frame 120, there is less or no hot feeling, resulting in a better user experience.
[0097] The third antenna 330 also includes two second grounding components 332. The second grounding components 332 are separate from the third radiator 331 and the middle plate 110, respectively. The two second grounding components 332 are spaced apart and electrically connected to the grounding terminal of the third radiator 331 to the middle plate 110 for grounding. Therefore, the second grounding components 332 can isolate the interference between the third antenna 330 and other surrounding antennas, so that the third antenna 330 and other antennas adjacent to the third antenna 330 have good antenna performance.
[0098] Furthermore, in one embodiment, one of the two second grounding members 332 facing away from the top frame 123 is electrically connected to a switch to the middle plate 110; the electrical connection of the two second grounding members 332 closer to the top frame 123 is matched to the middle plate 110. In one embodiment, a switch is also included on the path of the third feed source S3 electrically connected to the third feed point P3.
[0099] Please refer to the following: Figure 9 and Figure 12 , Figure 12 for Figure 9 The diagram illustrates the distance from the gap to the top frame in the electronic device shown. The fourth radiator 341 includes a free end and a ground end. The ground end of the fourth radiator 341 is located adjacent to the top frame 123 relative to the free end of the fourth radiator 341. The second side frame 124 has a gap 341a defining the ground end, and the distance d2 between the gap 341a and the top frame 123 satisfies: 28mm ≤ d2.
[0100] For ease of description, please refer to Figure 9 The free end of the fourth radiator 341 is named the fourth free end 3411, and the ground end of the fourth radiator 341 is named the fourth ground end 3412.
[0101] The grounding terminal of the fourth radiator 341 is positioned adjacent to the top frame 123 relative to the free end of the fourth radiator 341; that is, the fourth grounding terminal 3412 is positioned adjacent to the top frame 123 relative to the fourth free end 3411. The second side frame 124 has a gap 341a defining the grounding terminal; that is, the second side frame 124 has a gap 341a defining the fourth grounding terminal 3412.
[0102] In one embodiment, the upper limit of the distance d2 between the gap 341a and the top frame 123 is not limited. In another embodiment, the distance d2 can be, but is not limited to, 28mm ≤ d2 ≤ 40mm. For example, the distance d2 can be, but is not limited to, 28mm, 29mm, 30mm, 31mm, 32mm, 33mm, 34mm, 35mm, 36mm, 37mm, 38mm, 39mm, or 40mm.
[0103] The second side frame 124 has a gap 341a defining the grounding terminal. The distance d2 between the gap 341a and the top frame 123 satisfies: 28mm ≤ d2. This ensures that when the electronic device 1 is held by the user in landscape mode, the gap 341a is not easily blocked, reducing or even avoiding performance degradation of the fourth antenna 340 caused by the gap 341a being blocked. When the electronic device 1 is used by the user in landscape mode (e.g., playing games in landscape mode), the user's fingers will not touch the gap 341a, reducing the impact of the human body on the performance of the fourth antenna 340.
[0104] Please refer to further information. Figure 9 and Figure 10The fourth antenna 340 also includes two third grounding components 342. The third grounding components 342 and the fourth radiator 341 are separate structures. The two third grounding components 342 are spaced apart, and the third grounding components 342 are electrically connected to the grounding terminal of the fourth radiator 341 to the middle plate 110 for grounding.
[0105] In this embodiment, the third grounding terminal 3312 has two grounding points G4, which are spaced apart. The grounding points G4 are electrically connected to the third grounding component 342, and different grounding points G4 are electrically connected to different third grounding components 342.
[0106] In this embodiment, the fourth antenna 340 includes a third grounding component 342. The third grounding component 342 is a separate structure from both the fourth radiator 341 and the middle plate 110. The third grounding component 342 is electrically connected to the fourth grounding terminal 3412 to the middle plate 110 to ground the fourth grounding terminal 3412. The fact that the third grounding component 342 is a separate structure from both the fourth radiator 341 and the middle plate 110 means that the third grounding component 342 is not part of the structure of the fourth radiator 341, nor is it part of the structure of the middle plate 110. The specific structural form of the third grounding component 342 will be described in detail later.
[0107] The third grounding component 342 includes a weldable conductive component 3221 or a conductive spring 3222. The third grounding component 342 is partially electrically connected to the fourth grounding terminal 3412 and partially electrically connected to the middle plate 110.
[0108] The weldable conductive component 3221 can be, but is not limited to, a weldable steel sheet. When the third grounding component 342 is a weldable conductive component 3221, a portion of the weldable conductive component 3221 is electrically connected to the fourth grounding terminal 3412 via solder joints, and the remaining portion of the weldable conductive component 3221 is electrically connected to the middle plate 110 via other solder joints. When the third grounding component 342 includes a conductive spring 3222, the conductive spring 3222 can be detachably connected to the fourth grounding terminal 3412 of the fourth radiator 341 and the middle plate 110.
[0109] The third grounding component 342 provided in this application includes a weldable conductive component 3221 or a conductive spring 3222. On the one hand, it can ground the fourth grounding terminal 3412 to meet the grounding requirements of the fourth radiator 341. On the other hand, the heat from other components (such as the motherboard and other heat-generating devices) in the electronic device 1 is not easily dissipated to the frame 120, so that when the user holds the frame 120, there is less or no burning sensation, resulting in a better user experience.
[0110] The fourth antenna 340 also includes two third grounding components 342. The third grounding components 342 and the fourth radiator 341 are separate structures. The two third grounding components 342 are spaced apart, and the third grounding components 342 are electrically connected to the grounding terminal of the fourth radiator 341 to the middle plate 110 for grounding. Therefore, the third grounding components 342 can isolate the fourth antenna 340 from interference with other surrounding antennas, so that the fourth antenna 340 and other antennas adjacent to the fourth antenna 340 have good antenna performance.
[0111] Please refer to the following: Figure 13 and Figure 14 , Figure 13 A front view of a portion of the structure of an electronic device provided in yet another embodiment of this application; Figure 14 for Figure 13 The diagram shows a partial rear view equivalent of the structure of the electronic device. The antenna assembly 30 also includes a third antenna 330 and a fourth antenna 340. Both the third antenna 330 and the fourth antenna 340 support the second target frequency band. Furthermore, the antenna assembly 30 also includes a fifth antenna 350, which also supports the second target frequency band. The fifth antenna 350 includes a fifth radiator 351, which is located on the first side frame 122 and between the third radiator 331 and the second radiator 321.
[0112] The third antenna 330 and the fourth antenna 340 are described above and will not be repeated here. In this embodiment, the antenna assembly 30 further includes a fifth antenna 350, which also supports the second target frequency band. Therefore, the antenna assembly 30 includes three antennas that can support the second target frequency band, namely the third antenna 330, the fourth antenna 340, and the fifth antenna 350. When one or both of the third antenna 330, the fourth antenna 340, and the fifth antenna 350 are blocked and the communication performance is poor, the electronic device 1 can still use the remaining antennas to support the second target frequency band. Therefore, the antenna assembly 30 has good performance in the second target frequency band.
[0113] In one embodiment, the fifth radiator 351 is located on the first side frame 122, and is located on the upper half of the first side frame 122 adjacent to the top frame 123. In other words, when the electronic device 1 is in portrait mode, the fifth radiator 351 is located on the upper half of the electronic device 1.
[0114] In this embodiment, the fifth radiator 351 includes a free end and a ground end. For ease of description, the free end of the fifth radiator 351 is named the fifth free end 3511, and the ground end of the fifth radiator 351 is named the fifth ground end 3512. The fifth free end 3511 has a feed point P5 for electrical connection to a feed source. The fifth ground end 3512 is grounded. For example, the fifth ground end 3512 has a ground point G5, which is grounded. The gap 321a exists between the fifth free end 3511 and the second free end 3211 of the second radiator 321.
[0115] Accordingly, the fifth antenna 350 also includes a grounding component (not shown in the figure). The grounding component of the fifth antenna 350 is a separate structure from the fifth radiator 351 and the middle plate 110, and the grounding component of the fifth antenna 350 is electrically connected to the fifth grounding terminal 3512 to the middle plate 110 for grounding.
[0116] In one embodiment, the grounding component of the fifth antenna 350 includes a solderable conductive component 3221 or a conductive spring 3222. This allows the fifth grounding terminal 3512 to be grounded, satisfying the grounding requirement of the fifth radiator 351; furthermore, heat from other components in the electronic device 1 (such as the motherboard and other heat-generating devices) is less likely to dissipate to the frame 120, resulting in less or no burning sensation when the user holds the frame 120, thus providing a better user experience.
[0117] In one embodiment, the first antenna 310 is also used to support the second target frequency band, and the first antenna 310, the third antenna 330, the fourth antenna 340 and the fifth antenna 350 constitute a 4*4 Multiple-Input Multiple-Output (MIMO) antenna for the second target frequency band.
[0118] As described above, the first antenna 310 supports the first target frequency band. In this embodiment, the first antenna 310 is also used to support the second target frequency band, that is, the first antenna 310 supports both the first target frequency band and the second target frequency band. Therefore, the first antenna 310 can operate in both the first target frequency band and the second target frequency band, supporting more frequency bands and achieving better communication performance.
[0119] In one embodiment, the first target frequency band includes a low-frequency band, and the second target frequency band includes a mid-to-high frequency band. Therefore, the first antenna 310 can support both the low-frequency band and the mid-to-high frequency band.
[0120] The first antenna 310, the third antenna 330, the fourth antenna 340 and the fifth antenna 350 constitute a 4*4 Multiple-Input Multiple-Output (MIMO) antenna for the second target frequency band, which enables the antenna assembly 30 to utilize the transmission speed and system capacity of the second target frequency band for communication, as well as to have better anti-interference capability and wider coverage.
[0121] In conjunction with the electronic device 1 provided in any of the preceding embodiments, the second target frequency band includes the Middle High Band (MHB) frequency band. The inclusion of the MHB frequency band in the second target frequency band enables the antenna assembly 30 to support communication in the MHB frequency band, thus meeting the communication requirements of the electronic device 1 in the MHB frequency band.
[0122] Please refer to the following: Figure 15 and Figure 16 , Figure 15 A front view of a portion of the structure of an electronic device provided in yet another embodiment of this application; Figure 16 for Figure 15 The diagram shows a partial rear view equivalent of the structure of the electronic device. Furthermore, the fourth antenna 340 is also used to support the third target frequency band. The antenna assembly 30 also includes a sixth antenna 360, which is also used to support the third target frequency band. The sixth antenna 360 includes a sixth radiator 361, which is located on the first side frame 122 and between the third radiator 331 and the fifth radiator 351.
[0123] As described above, the fourth antenna 340 supports the second target frequency band. In this embodiment, the fourth antenna 340 is also used to support the third target frequency band, that is, the fourth antenna 340 supports both the second and third target frequency bands. Therefore, the fourth antenna 340 can operate in both the second and third target frequency bands, supporting more frequency bands and achieving better communication performance.
[0124] In one embodiment, the second target frequency band includes a mid-to-high frequency band, and the third target frequency band includes an ultra-high frequency band. Therefore, the first antenna 310 can support both mid-to-high frequency bands and ultra-high frequency bands. In one embodiment, the third target frequency band includes the N78 band in the ultra-high frequency band, but it is not limited to this.
[0125] In this embodiment, the sixth radiator 361 includes a free end and a ground end. For ease of description, the free end of the sixth radiator 361 is named the sixth free end 3611, and the ground end of the sixth radiator 361 is named the sixth ground end 3612. The sixth ground end 3612 is grounded.
[0126] In one embodiment, the sixth radiator 361 is connected to the grounding terminal of the fifth radiator 351. Specifically, the sixth grounding terminal 3612 is connected to the fifth grounding terminal 3512. Thus, the sixth radiator 361 and the fifth radiator 351 can share the same grounding element.
[0127] In this embodiment, the sixth radiator 361 and the fifth radiator 351 can be an integral structure, and the grounding terminals of the sixth radiator 361 and the fifth radiator 351 are connected. This reduces the number of seams in the frame 120, resulting in higher structural strength for the frame 120.
[0128] The third antenna 330 is also used to support a third target frequency band.
[0129] As described above, the third antenna 330 supports the second target frequency band. In this embodiment, the third antenna 330 is also used to support the third target frequency band. Therefore, the third antenna 330 supports both the second target frequency band and the third target frequency band, thus supporting more frequency bands and having better performance.
[0130] In one embodiment, the third target frequency band includes an ultra-high frequency (UHF) band. For example, the third antenna 330 may support the N78 band within the UHF band.
[0131] In one embodiment, the second target frequency band includes a mid-to-high frequency band, and the third target frequency band includes an ultra-high frequency band. Therefore, the third antenna 330 can support both the mid-to-high frequency band and the ultra-high frequency band (i.e., MHB band + UHB band). For example, the third antenna 330 can support N78 of the mid-to-high frequency band and the ultra-high frequency band (i.e., MHB band + N78 band).
[0132] Please refer to the following: Figure 17 and Figure 18 , Figure 17 A front view of a portion of the structure of an electronic device provided in yet another embodiment of this application; Figure 18 for Figure 17The diagram shows a partial rear view of the electronic device. The antenna assembly 30 also includes a seventh antenna 370. The seventh antenna 370 supports a third target frequency band. The seventh antenna 370 includes a seventh radiator 371 located on the top bezel 123. The third antenna 330, the fourth antenna 340, the sixth antenna 360, and the seventh antenna 370 constitute a 4x4 MIMO antenna for the third target frequency band.
[0133] The seventh radiator 371 is located on the top frame 123, thus reducing or even eliminating the influence of the human body on the seventh antenna 370 when it receives the third target frequency band.
[0134] The third antenna 330, the fourth antenna 340, the sixth antenna 360, and the seventh antenna 370 constitute a 4*4 MIMO antenna for the third target frequency band, which enables the antenna assembly 30 to utilize the third target frequency band for communication, improves transmission speed and system capacity, and provides better anti-interference capabilities and a wider coverage area.
[0135] The seventh radiator 371 includes a free end and a ground end. The ground end of the seventh radiator 371 is disposed adjacent to the first side frame 122 relative to the free end of the seventh radiator 371. The seventh antenna 370 also includes two fourth grounding elements 372. The fourth grounding elements 372 are separately structured from the seventh radiator 371 and the middle plate 110. The two fourth grounding elements 372 are spaced apart, and the fourth grounding elements 372 are electrically connected to the ground end of the seventh radiator 371 to the middle plate 110 for grounding.
[0136] In this embodiment, the seventh radiator 371 includes a free end and a ground end. For ease of description, the free end of the seventh radiator 371 is named the seventh free end 3711, and the ground end of the seventh radiator 371 is named the seventh ground end 3712. The seventh free end 3711 has a seventh feed point P7 for connecting to the feed source. The seventh ground end 3712 has two grounding points G7 spaced apart, and the grounding points G7 are grounded.
[0137] In this embodiment, the seventh antenna 370 includes a fourth grounding component 372. The fourth grounding component 372 is a separate structure from both the seventh radiator 371 and the middle plate 110. The fourth grounding component 372 is electrically connected to the seventh grounding terminal 3712 to the middle plate 110 to ground the seventh grounding terminal 3712. The separate structure of the fourth grounding component 372 from both the seventh radiator 371 and the middle plate 110 means that the fourth grounding component 372 is not part of the structure of the seventh radiator 371, nor is it part of the structure of the middle plate 110. The specific structural form of the fourth grounding component 372 will be described in detail later. In this embodiment, the fourth grounding component 372 is electrically connected to the grounding point G7, and different fourth grounding components 372 are electrically connected to different grounding points G7.
[0138] The fourth grounding component 372 includes a weldable conductive component 3221 or a conductive spring 3222. The fourth grounding component 372 is partially electrically connected to the seventh grounding terminal 3712 and partially electrically connected to the middle plate 110.
[0139] The weldable conductive component 3221 can be, but is not limited to, a weldable steel sheet. When the fourth grounding component 372 is a weldable conductive component 3221, a portion of the weldable conductive component 3221 is electrically connected to the seventh grounding terminal 3712 via solder joints, and the remaining portion of the weldable conductive component 3221 is electrically connected to the middle plate 110 via other solder joints. When the fourth grounding component 372 includes a conductive spring 3222, the conductive spring 3222 can be detachably connected to the seventh grounding terminal 3712 of the seventh radiator 371 and the middle plate 110.
[0140] The fourth grounding component 372 provided in this application includes a weldable conductive component 3221 or a conductive spring 3222. On the one hand, it can ground the seventh grounding terminal 3712 to meet the grounding requirements of the seventh radiator 371. On the other hand, the heat from other components (such as the motherboard and other heat-generating devices) in the electronic device 1 is not easily dissipated to the frame 120, so that when the user holds the frame 120, there is less or no burning sensation, resulting in a better user experience.

[0142] The seventh antenna 370 also includes two fourth grounding components 372. The fourth grounding components 372 are separate from the seventh radiator 371 and the middle plate 110, respectively. The two grounding components are spaced apart and electrically connected to the grounding terminal of the seventh radiator 371 to the middle plate 110 for grounding. Therefore, the fourth grounding components 372 can isolate the seventh antenna 370 from interference with other surrounding antennas, so that the seventh antenna 370 and other antennas adjacent to the seventh antenna 370 have good antenna performance.
[0143] Please see Figure 19 and Figure 20 , Figure 19 A front view of a portion of the structure of an electronic device provided in yet another embodiment of this application; Figure 20 for Figure 19 The diagram shows a partial rear view of the electronic device. The antenna assembly 30 also includes an eighth antenna 380 and a ninth antenna 390. Both the eighth antenna 380 and the ninth antenna 390 are used to support a fourth target frequency band. The eighth antenna 380 includes an eighth radiator 381, which is partially located on the top frame 123 and partially on the second side frame 124. The ninth antenna 390 includes a ninth radiator 391, which is located on the second side frame 124.
[0144] Both the eighth antenna 380 and the ninth antenna 390 are used to support the fourth target frequency band. Therefore, the antenna assembly 30 can support more frequency bands and meet the multi-band communication needs of the electronic device 1.
[0145] In one embodiment, the fourth target frequency band includes the Wireless Fidelity (WiFi) 2.4G band, i.e., the WiFi 2.4G band. For example, the eighth antenna 380 supports channel 0 (CH0) of the WiFi 2.4G band, and the ninth antenna 390 supports channel 1 (CH1) of the WiFi 2.4G band. In one embodiment, when the antenna assembly 30 operates in the fourth target frequency band, the antenna with the better signal strength between the eighth antenna 380 and the ninth antenna 390 can be selected to operate.
[0146] In this embodiment, the eighth radiator 381 and the ninth radiator 391 are both located in the upper half of the electronic device 1. This reduces the obstruction of the eighth radiator 381 and the ninth radiator 391 by the user, thereby enabling the antenna assembly 30 to have better communication performance in the fourth target frequency band.
[0147] In one embodiment, the eighth radiator 381 and the ninth radiator 391 are integrally formed, with the grounding terminal of the eighth radiator 381 and the grounding terminal of the ninth radiator 391 connected as a single unit. This reduces the number of gaps in the frame 120 when forming the eighth radiator 381 and the ninth radiator 391, resulting in relatively better structural strength for the frame 120.
[0148] Further, please refer to Figure 21 , Figure 22 and Figure 23 , Figure 21 A front view of a portion of the structure of an electronic device provided in yet another embodiment of this application; Figure 22 for Figure 21 A rear-view equivalent schematic diagram of a portion of the structure of an electronic device in the diagram; Figure 23 for Figure 22 The diagram shows the environment of each antenna of the electronic device. The eighth antenna 380 and the ninth antenna 390 are also used to support the fifth target frequency band. The antenna assembly 30 also includes a tenth antenna 400, which is used to support the fifth target frequency band.
[0149] As described above, both the eighth antenna 380 and the ninth antenna 390 are used to support the fourth target frequency band. In this embodiment, both the eighth antenna 380 and the ninth antenna 390 are also used to support the fifth target frequency band. Therefore, the eighth antenna 380 can support both the fourth and fifth target frequency bands, and the ninth antenna 390 can also support both the fourth and fifth target frequency bands. Thus, both the eighth antenna 380 and the ninth antenna 390 can support multiple frequency bands, satisfying the communication requirements of the antenna assembly 30 in the fourth and fifth target frequency bands.
[0150] Furthermore, the antenna assembly 30 also includes a tenth antenna 400, which supports the fifth target frequency band. Therefore, the antenna assembly 30 has a plurality of antennas (eighth antenna 380, ninth antenna 390, and tenth antenna 400) that can support the fifth target frequency band. When one or both of the eighth antenna 380, the ninth antenna 390, and the tenth antenna 400 are blocked, the remaining antennas can be selected to support the fifth target frequency band, thereby enabling the antenna assembly 30 to have better communication performance in the fifth target frequency band.
[0151] Furthermore, in one embodiment, the eighth antenna 380 supports both the fourth and fifth target frequency bands via a time-division multiplexing method. Specifically, the eighth antenna 380's support for the fourth and fifth target frequency bands includes multiple cycles. One cycle includes a first time period and a second time period. During the first time period of one cycle, the eighth antenna 380 supports one of the fourth and fifth target frequency bands; during the second time period of the same cycle, the eighth antenna 380 supports the other of the fourth and fifth target frequency bands. The eighth antenna 380 may include a feed source supporting the fourth target frequency band, a feed source supporting the fifth target frequency band, and a switching switch. When the eighth antenna 380 supports the fourth target frequency band, the switching switch switches the feed source supporting the fourth target frequency band to the feed point of the eighth radiator 381; when the eighth antenna 380 supports the fifth target frequency band, the switching switch switches the feed source supporting the fifth target frequency band to the feed point of the eighth radiator 381. Therefore, when the eighth antenna 380 supports the fourth and fifth target frequency bands, it is necessary to frequently switch using a switching switch.
[0152] In one embodiment, the ninth antenna 390 supports the fifth target frequency band and the fifth target frequency band in a time-division multiplexing manner. Specifically, the ninth antenna 390 supports the fifth target frequency band and the fifth target frequency band in multiple cycles. One cycle includes a third time period and a fourth time period. During the third time period of one cycle, the ninth antenna 390 supports one of the fifth target frequency band and the fifth target frequency band; during the fourth time period of the same cycle, the ninth antenna 390 supports the other of the fifth target frequency band and the fifth target frequency band. The ninth antenna 390 may include a feed source supporting the fifth target frequency band, a feed source supporting the fifth target frequency band, and a switching switch. When the ninth antenna 390 supports the fifth target frequency band, the switching switch switches the feed source supporting the fifth target frequency band to the feed point of the ninth radiator 391; when the ninth antenna 390 supports the fifth target frequency band, the switching switch switches the feed source supporting the fifth target frequency band to the feed point of the ninth radiator 391. Therefore, when the ninth antenna 390 supports the fourth and fifth target frequency bands, it is necessary to frequently switch using a switching switch.
[0153] The tenth antenna 400 includes a tenth radiator 401, which is disposed corresponding to the middle plate 110. In one embodiment, the tenth radiator 401 is a flexible printed circuit board (FPC) radiator.
[0154] The antenna assembly 30 further includes a tenth antenna 400, which supports the fifth target frequency band. Therefore, the antenna assembly 30 includes three antennas that can support the fifth target frequency band: the eighth antenna 380, the ninth antenna 390, and the tenth antenna 400. Thus, the antenna assembly 30 has good communication performance in the fifth target frequency band.
[0155] When the eighth antenna 380 supports the fourth target frequency band, the antenna assembly 30 can utilize the tenth antenna 400 to support the fifth target frequency band, thus eliminating the need to switch the eighth antenna 380 to the fifth target frequency band. Therefore, when the antenna assembly 30 supports the fifth target frequency band, there is no latency issue between the fifth target frequency band and the fourth target frequency band, thereby resolving the throughput problem of the fourth target frequency band and the latency problem of the fifth target frequency band when the antenna assembly 30 supports both.
[0156] Accordingly, when the ninth antenna 390 hosts the fourth target frequency band, the antenna assembly 30 can utilize the tenth antenna 400 to support the fifth target frequency band, thus eliminating the need to switch the ninth antenna 390 to the fifth target frequency band. Therefore, when the antenna assembly 30 supports the fifth target frequency band, there is no latency issue between the fifth target frequency band and the fourth target frequency band, thereby resolving the throughput problem of the fourth target frequency band and the latency problem of the fifth target frequency band when the antenna assembly 30 supports both.
[0157] In one embodiment, the fourth target frequency band includes the WiFi 2.4G frequency band, and the fifth target frequency band includes the Bluetooth (BT) frequency band.
[0158] The fourth target frequency band includes the WiFi 2.4G frequency band, and the fifth target frequency band includes the Bluetooth frequency band. Therefore, the communication requirements of the antenna assembly 30 in the WiFi 2.4G frequency band and the Bluetooth frequency band can be met.
[0159] In one embodiment of the electronic device 1, the eighth antenna 380 and the ninth antenna 390 operate in the fourth target frequency band, and neither the eighth antenna 380 nor the ninth antenna 390 operates in the fifth target frequency band; the tenth antenna 400 operates in the fifth target frequency band. Therefore, the latency problem of the fifth target frequency band compared to the fourth target frequency band in the antenna assembly 30 can be solved. Furthermore, since the eighth antenna 380 and the ninth antenna 390 do not need to support the fifth target frequency band, the eighth antenna 380 and the ninth antenna 390 support the fourth target frequency band for all times. Therefore, the antenna assembly 30 has a larger throughput in the fourth target frequency band.
[0160] The electronic device 1 provided in this embodiment has an eighth antenna 380 and a ninth antenna 390 operating in the WiFi 2.4G band, while neither the eighth antenna 380 nor the ninth antenna 390 operates in the Bluetooth band; the tenth antenna 400 operates in the Bluetooth band. Therefore, the latency problem of the Bluetooth band compared to the WiFi 2.4G band in the antenna assembly 30 can be solved. Furthermore, since the eighth antenna 380 and the ninth antenna 390 do not need to support the Bluetooth band, they support the WiFi 2.4G band for all time (i.e., they do not need to allocate time to support the Bluetooth band). Therefore, the antenna assembly 30 has a large throughput in the WiFi 2.4G band.
[0161] Furthermore, in one embodiment, the ninth antenna 390 and the tenth antenna 400 are also used to support a sixth target frequency band, wherein the sixth target frequency band includes the WiFi 5G frequency band.
[0162] The ninth antenna 390 and the tenth antenna 400 are also used to support a sixth target frequency band, which includes the WiFi 5G frequency band. Therefore, the communication requirements of the antenna assembly 30 in the WiFi 5G frequency band can be met.
[0163] Furthermore, the eighth antenna 380 is also used to support a seventh target frequency band, wherein the seventh target frequency band includes the Global Positioning System (GPS) L1 band, i.e., the GPS L1 band.
[0164] The eighth antenna 380 is also used to support a seventh target frequency band, which includes the GPS L1 frequency band, thus satisfying the communication needs of the antenna assembly 30 in the GPS L1 frequency band.
[0165] In one embodiment, the eighth antenna 380 is used to support the fourth target frequency band, the fifth target frequency band, and the seventh target frequency band. When the fourth target frequency band includes the WiFi 2.4G frequency band, the fifth target frequency band includes the Bluetooth frequency band, and the seventh target frequency band includes the GPS L1 frequency band, the eighth antenna 380 can support the WiFi 2.4G frequency band, the Bluetooth frequency band, and the GPS L1 frequency band.
[0166] In one embodiment, the seventh antenna 370 is used to support an eighth target frequency band, wherein the eighth target frequency band includes the GPS L5 band.
[0167] The seventh antenna 370 is also used to support an eighth target frequency band, which includes the GPS L5 band, thus satisfying the communication requirements of the antenna assembly 30 in the GPS L5 band.
[0168] Please continue reading. Figure 21 , Figure 22 and Figure 23 In one embodiment, the antenna assembly 30 further includes an eleventh antenna 410 for supporting a ninth target frequency band, wherein the ninth target frequency band includes the Near Field Communication (NFC) band.
[0169] The antenna assembly 30 also includes an eleventh antenna 410, which supports a ninth target frequency band, including the NFC frequency band. Therefore, the antenna assembly 30 can meet the communication requirements of the NFC frequency band.
[0170] The eleventh antenna 410 includes an eleventh radiator 411, which can be, but is not limited to, a flexible printed circuit board (FPC) radiator. The eleventh antenna 410 is provided corresponding to the middle plate 110.
[0171] Please see Figure 23 The electronic device 1 further includes a button 810, a front-facing camera 820, a camera decorative ring 830, a battery 840, a speaker 850, a USB interface 860, and a SIM slot 870. The fourth radiator 341 is disposed adjacent to the button 810. The seventh radiator 371 is disposed adjacent to the front-facing camera 820. The tenth radiator 401 and the eleventh radiator 411 are disposed adjacent to the camera decorative ring 830. The battery 840 is disposed adjacent to the bottom frame 121. The speaker 850, the USB interface 860, and the SIM slot 870 are all disposed adjacent to the bottom frame 121, and are all located closer to the bottom frame 121 than the battery 840.
[0172] It should be noted that each of the fifth to eleventh antennas 410 in the electronic device 1 described in the preceding embodiments includes a feed source. Correspondingly, each radiator in the fifth to eleventh antennas 410 in the electronic device 1 described in the preceding embodiments has a feed point, and the feed point of each radiator is electrically connected to the corresponding feed source. For example, the Nth antenna includes the Nth radiator and the Nth feed source S. N The Nth radiator has a feed point P. N The Nth feed source S N The feed point P of the N-radiator is electrically connected to the ground. N Where N equals one of five, six, seven, eight, nine, ten, or eleven.
[0173] In summary, the electronic device 1 provided in one embodiment of this application includes two low-frequency antennas, four mid-high frequency + ultra-high frequency antennas, a dual-band WiFi MIMO antenna, three Bluetooth antennas, and one NFC antenna. It uses a frame 120 as the antenna radiator in a very small space and uses an FPC radiator to place the antenna in the upper half of the electronic device 1 when it is in portrait mode.
[0174] In one embodiment, the electronic device 1 includes two low-frequency antennas, namely a first antenna 310 and a second antenna 320. The first radiator 311 of the first antenna 310 is located at the bottom of the electronic device 1, and the second radiator 321 of the second antenna 320 is located at the waist of the electronic device 1. Furthermore, by designing a distance between the gap 321a of the second free end 3211 of the second radiator 321 and the bottom frame 121, when the electronic device 1 is in portrait mode, the user will not hold the electronic device 1 at the gap 321a. Conversely, when the electronic device 1 is in portrait mode, the user's hand will hold the second radiator 321. Based on human body enhancement technology, the radiation efficiency of the second antenna 320 supporting the low-frequency band is improved.
[0175] In one embodiment, the electronic device 1 simultaneously supports four antennas for the mid-to-high frequency band and four antennas for the ultra-high frequency band (such as the N78 band), a layout design based on the human body's influence when the user uses the electronic device 1. When the electronic device 1 is in portrait mode, the main antenna (i.e., the third antenna 330) that simultaneously supports the mid-to-high frequency band and the ultra-high frequency band (such as the N78 band) is located in the upper right corner of the electronic device 1, minimizing the impact of the human body on the third antenna 330 when the electronic device 1 is held with one hand.
[0176] In one embodiment, the fourth antenna 340 in the electronic device 1 can be placed at the button position of the electronic device 1. By designing the distance from the gap 341a at the ground end of the fourth radiator 341 of the fourth antenna 340 to the top frame 123, when the electronic device 1 is in landscape mode (e.g., in a landscape game scenario), the user's fingers will rarely or never touch the gap 341a, thereby reducing the impact of the human body on the fourth antenna 340.
[0177] In one embodiment, the electronic device 1 includes three Bluetooth antennas, namely the eighth antenna 380, the ninth antenna 390, and the tenth antenna 400. The tenth antenna 400 can solve the problems of WiFi throughput and Bluetooth latency when WiFi 2.4G band and Bluetooth band coexist.
[0178] Furthermore, in the electronic device 1, multiple antennas supporting the same frequency band are not adjacent, which increases the isolation between these antennas. Additionally, for antennas with poor isolation, the number and length of grounding elements are increased in the corresponding antenna to improve the isolation between the corresponding antenna and other surrounding antennas. For example, two grounding elements are provided in the corresponding antenna (e.g., the third antenna 330 described above includes two second grounding elements 332, the fourth antenna 340 includes two third grounding elements 342, and the seventh antenna 370 includes two fourth grounding elements 372) to improve the isolation between the corresponding antenna and other surrounding antennas. The grounding elements can be weldable steel sheets.
[0179] It should be noted that in the electronic device 1 provided in this application embodiment, the grounding components of each antenna (first grounding component 322, second grounding component 332, third grounding component 342 and fourth grounding component 372) and the middle plate 110 and the radiators of the corresponding antennas are separate structures. When the grounding component is connected to the middle plate 110 and the radiators of the corresponding antennas, it is a point contact. Therefore, the heat from other components (such as the motherboard and other heat-generating devices) in the electronic device 1 is not easily dissipated to the frame 120, so that when the user holds the frame 120, there is less or no hot feeling, resulting in a better user experience.
[0180] Furthermore, in order to dissipate heat from other components (also referred to as heat-generating components, such as the motherboard) in the electronic device 1, the electronic device 1 includes a heat sink. The heat sink transfers heat from the other components (also referred to as heat-generating components, such as the motherboard) to at least one of the screen 50 and the back cover 70 of the electronic device 1. Since users typically hold the electronic device 1 more easily with their hands on the bezel 120 and less frequently with their hands on the screen 50 and the back cover 70, the heat sink of the electronic device 1 dissipates heat from the other components (also referred to as heat-generating components, such as the motherboard) via at least one of the screen 50 and the back cover 70, ensuring that the other components operate at a suitable temperature.
[0181] In one embodiment, the middle plate 110 and the frame 120 of the mid-frame assembly 10 of the electronic device 1 are separate structures, connected together by an insulating component 130. This embodiment is also referred to as the splicing scheme of the mid-frame assembly 10 of the electronic device 1. The middle plate 110 can be formed using a low-cost die-casting or stamping process, without the need for a high-cost CNC process, thus saving costs on the mid-frame assembly 10. Furthermore, the frame 120 can be formed using a CNC process, thereby ensuring the aesthetic appearance of the electronic device 1. Therefore, the electronic device 1 provided by this application embodiment can save costs while meeting aesthetic requirements. In addition, the splicing scheme of the mid-frame assembly 10 of the electronic device 1 provided by the above embodiment can solve the problem of frame 120 overheating caused by other components of the electronic device 1 (also referred to as heat-generating components, such as the motherboard and other heat-generating devices), improving the user experience. Furthermore, the electronic device 1 provided by this application embodiment also improves antenna performance and enhances the user experience by designing each antenna of the antenna assembly 30.
[0182] Please see Figure 24 , Figure 24 This is a schematic diagram showing the performance of each antenna in the antenna assembly of an electronic device according to an embodiment of this application. The columns labeled "Antenna" represent each antenna, with the Nth antenna (ANT) designated as ANTN, for example, the first antenna 310 designated as ANT1, and so on. Taking the first antenna 310 as an example, when the first antenna 310 supports B28 TX (i.e., the transmission frequency band of the B28 band), its efficiency is -9.02; when the first antenna 310 supports B28 RX (i.e., the reception frequency band of the B28 band), its efficiency is -8.75. It can be seen that the efficiency of each antenna in the electronic device 1 provided by this embodiment of the application is good in the supported frequency bands. Therefore, the electronic device 1 provided by this embodiment of the application not only solves the technical problem of high temperature of the frame 120, but also maintains high efficiency of each antenna in the antenna assembly 30, without sacrificing antenna efficiency.
[0183] The above description represents some embodiments of this application. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.
