The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application.

[0047] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate directions or positional relationships based on the attached Figure 1 The orientation or positional relationship shown is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0048] It should be understood that in this application, "electrical connection" can be understood as physical contact and electrical conduction between components; it can also be understood as a form of connection between different components in the circuit structure through physical lines such as printed circuit board (PCB) copper foil or wires that can transmit electrical signals. "Communication connection" can refer to electrical signal transmission, including wireless communication connection and wired communication connection. Wireless communication connection does not require a physical medium and does not belong to a connection relationship that limits the product structure. "Connection" and "connected" can both refer to a mechanical connection relationship or a physical connection relationship, that is, A is connected to B or A is connected to B, which can mean that there is a fastening component (such as screws, bolts, rivets, etc.) between A and B, or A and B are in contact with each other and A and B are difficult to separate.

[0049] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those of ordinary skill in the art.

[0050] The antenna design of high-end mobile phones is basically limited to the middle frame antenna design. The design of the middle frame antenna is generally limited to the overall size of the mobile phone. In particular, as the number of antennas increases, the area occupied by the mobile phone frame becomes larger, resulting in an increase in the cost of the entire machine. Innovations based on the middle frame antenna mainly focus on reducing the use of switches and merging multiple antennas.

[0051] The design of the middle frame antenna in the related technology is mainly a combination of MHB antenna + WIFI 2.4 + 6E. The MHB part in the antenna solution of some mobile phones with narrow frames may also require a switch to cut out the medium and high frequency band antennas. The disadvantage of this solution is that the fused antenna bands are relatively small, and the combination of WIFI2.4 + 6E is difficult to debug due to the short frame size, and cannot achieve excellent antenna performance indicators. At the same time, the MHB part may also require the use of a switch to complete the design of the entire solution.

[0052] At the same time, when the middle frame antenna solution is a combination of MHB antenna + WIFI 2.4 + 6E, the middle frame length requirement is relatively high, which poses certain challenges to the overall antenna stacking.

[0053] Therefore, the present application provides an antenna structure that can increase the current flow path as much as possible, ensure the broadband performance of the first radiating branch, enable the first antenna component to cover more frequency bands, and reduce the design difficulty of the antenna structure.

[0055] The present application also provides an electronic device. Specifically, the electronic device can be any of various types of computer system devices that are mobile or portable and perform wireless communication. Specifically, the electronic device can be a mobile phone or smart phone (e.g., a phone based on iPhone TM, a phone based on Android TM), a portable game device (e.g., Nintendo DS TM, PlayStation Portable TM, Gameboy Advance TM, iPhone TM), a laptop, a PDA, a portable Internet device, a music player, and a data storage device, other handheld devices, and such as headphones, etc. The electronic device can also be other wearable devices that need to be charged (e.g., a head-mounted device (HMD) such as an electronic bracelet, an electronic necklace, an electronic device, or a smart watch).

[0056] The electronic device can also be any one of a plurality of electronic devices, including but not limited to cellular phones, smart phones, other wireless communication devices, personal digital assistants, audio players, other media players, music recorders, video recorders, other media recorders, radios, medical devices, vehicle transportation instruments, calculators, programmable remote controls, pagers, laptop computers, desktop computers, printers, netbook computers, personal digital assistants (PDAs), portable multimedia players (PMPs), Moving Picture Experts Group (MPEG-1 or MPEGG-2) Audio Layer 3 (MP3) players, portable medical devices, and digital cameras and combinations thereof.

[0057] In some cases, the electronic device can perform multiple functions (e.g., play music, display video, store pictures, and receive and send phone calls). If desired, the electronic device can be a device such as a cellular phone, a media player, other handheld device, a wristwatch device, a pendant device, a handset device, or other compact portable device.

[0058] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0059] On the one hand, combined with Figure 1 and Figure 2 As shown, this embodiment provides an antenna structure, and the antenna structure includes: a first antenna component 1.

[0060] The first antenna assembly 1 includes a first radiation branch 11, a first matching circuit 12 and a first RF port 13; a first feeding point 111 and a first grounding point 112 are provided on the first radiation branch 11, and the first matching circuit 12 is electrically connected between the first feeding point 111 and the first RF port 13; the first matching circuit 12 includes a matching trace 121 and at least one first electronic component 122, the length of the matching trace 121 is greater than or equal to the first target value, at least one first electronic component 122 is electrically connected to the matching trace 121, one end of the matching trace 121 is electrically connected to the first feeding point 111, and the other end of the matching trace 121 is the first RF port 13.

[0061] In the antenna structure of this embodiment, the first antenna component 1 includes a first radiation branch 11, and the first matching circuit 12 between the first radiation branch 11 and the first RF port 13 has a matching trace 121. The length of the matching trace 121 is greater than or equal to the first target value, so that the first matching circuit 12 can increase the current flow path as much as possible, ensuring the broadband performance of the first radiation branch 11, so that the first antenna component 1 can cover more frequency bands, which is conducive to reducing the design difficulty of the antenna structure.

[0062] The number of the first electronic components 122 in the first matching circuit 12 is, for example, one, two, three, four, etc., and the types of the first electronic components 122 include but are not limited to capacitors, inductors, resistors, etc.

[0063] In some possible implementations, the antenna structure further includes a circuit board 4, the first matching circuit 12 and the first RF port 13 are respectively located on the circuit board 4, and the circuit board 4 is arranged close to the first radiation branch 11. Optionally, the circuit board 4 and the first radiation branch 11 are electrically contacted through a metal spring to achieve electrical connection between the first matching circuit 12 and the first feeding point 111.

[0064] Exemplarily, the circuit board 4 includes a printed circuit board (PCB), a flexible printed circuit board (FPC), a rigid-flexible board, and the like.

[0065] In some embodiments, the first target value ranges from 5 mm to 9 mm. When the matching trace 121 in the first antenna component 1, that is, the flow path of the current, satisfies the above-mentioned value range, the flow path of the current of the first matching circuit 12 is larger, so that the first radiation branch 11 has better broadband performance, and the first antenna component 1 can cover more frequency bands.

[0066] In some possible implementations, the first target value is, for example, 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, 8.5 mm, 9 mm, etc. Optionally, the first target value is 7 mm, that is, the length of the matching line 121 is greater than or equal to 7 mm. Further, the length of the matching line 121 is equal to 7 mm.

[0067] Combination Figure 2 As shown, in some embodiments, a plurality of ground hole structures 123 are respectively disposed on both sides of the matching line 121 , and the plurality of ground hole structures 123 are arranged at intervals along the extension direction of the matching line 121 .

[0068] Among them, ground vias refer to holes punched in the metal layer of a circuit board and filled with conductive materials. The function of a ground via is to provide a grounding point for the circuit board to facilitate connecting the circuit board to a ground pin or ground wire. The location and number of ground vias can be determined according to the specific circuit design requirements. In a specific circuit design, the number and location of ground vias are very important because this will directly affect the performance and reliability of the circuit board.

[0069] In this embodiment, by arranging the ground hole structures 123 at intervals on both sides of the matching line 121, an electromagnetic isolation effect can be achieved, thereby avoiding mutual interference between the matching line 121 and other electronic components on the circuit board, and improving the working reliability of the first antenna assembly 1.

[0070] Combination Figure 2 As shown, in some embodiments, a grounding screw 124 is provided on one side of the matching line 121 , and the distance between the grounding screw 124 and the matching line 121 ranges from 0.7 mm to 1.1 mm.

[0071] A grounding screw 124 is arranged on one side of the matching line 121 , and the distance between the grounding screw 124 and the matching line 121 is limited to meet the above value range, which is conducive to ensuring the stability and reliability of the working performance of the first antenna component 1 .

[0072] In some possible implementations, when the matching trace 121 is located on the circuit board 4 , the grounding screw 124 is passed through the circuit board 4 and connects the circuit board 4 to the metal middle frame of the electronic device to achieve grounding of the circuit board 4 .

[0073] In some other possible implementations, the distance between the ground screw 124 and the matching trace 121 is, for example, 0.7 mm, 0.75 mm, 0.8 mm, 0.85 mm, 0.9 mm, 0.95 mm, 1.0 mm, 1.05 mm, 1.1 mm, etc. Optionally, the distance between the ground screw 124 and the matching trace 121 is 0.9 mm.

[0074] In some embodiments, the matching trace 121 is a surface trace structure of the circuit board 4 .

[0075] The surface wiring structure, i.e., surface wiring, refers to the circuit wiring arranged on the surface of the PCB (Printed Circuit Board). In circuit design, the wires and pins of electronic components are directly arranged on the surface of the PCB to achieve circuit connection and signal transmission.

[0076] In some embodiments, the surface wiring uses printing technology to print the conductor pattern on the surface of the PCB. This wiring method is more common and intuitive than the inner wiring (internal routing through a multi-layer PCB board). Optionally, the surface wiring uses copper foil as the conductor material, and the excess copper foil is removed by chemical etching or mechanical processing to form the required matching routing 121.

[0077] The advantages of surface wiring are simple wiring process, good visibility and easy maintenance. It makes the circuit board manufacturing process more efficient and can meet a variety of different circuit wiring requirements. In addition, surface wiring can also achieve higher wiring density and shorter signal transmission paths, which helps to improve the performance and reliability of the circuit.

[0078] Combination Figure 1 and Figure 2 As shown, in some embodiments, at least one first electronic component 122 includes a first capacitor 1221 and a second capacitor 1222 , and the first capacitor 1221 and the second capacitor 1222 are arranged in series on the matching trace 121 .

[0079] Through the above arrangement, the first matching circuit 12 can realize the combination of WIFI 6E+N77 / 78 / 79 antenna without the help of switching elements, and does not require additional power-consuming devices such as switching elements, thereby reducing the design difficulty of the antenna structure.

[0080] In some possible implementations, the first capacitor 1221 and the second capacitor 1222 are arranged at one end of the matching trace 121 close to the first feeding point 111 , which helps to improve the bandwidth performance of the first antenna assembly 1 .

[0081] Combination Figure 1 As shown, in some embodiments, the first feeding point 111 is close to the first end 1101 of the first radiation branch 11 , and the first grounding point 112 is located at the second end 1102 of the first radiation branch 11 .

[0082] The distance between the first end 1101 and the second end 1102 of the first radiation branch 11 is L1, and the distance between the first feeding point 111 and the first end 1101 is L2. The value range of L1 is 5mm-9mm, and the value range of L2 is 0.5mm-5.5mm.

[0083] When the relevant dimensions of the first radiation branch 11 meet the above-mentioned value range, the first antenna component 1 can achieve the frequency band coverage of WIFI 6E+N77 / 78 / 79 without the need for additional power-consuming devices such as switching elements, thereby reducing the design difficulty of the antenna structure.

[0084] In some possible implementations, the distance L1 between the first end 1101 and the second end 1102 of the first radiation branch 11 is, for example, 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, 8.5 mm, 9 mm, etc. Optionally, the value of L1 is 7 mm.

[0085] In some other possible implementations, the distance L2 between the first feeding point 111 and the first end 1101 is, for example, 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, 5.5 mm, etc. Optionally, the value of L2 is 2.5 mm.

[0086] Combination Figure 1 As shown, in some embodiments, the antenna structure further includes a second antenna assembly 2 .

[0087] The second antenna component 2 includes a second radiating branch 21, a second matching circuit 22 and a second RF port 23; the second radiating branch 21 and the first radiating branch 11 are arranged end to end, and a break structure 3 is provided between the second radiating branch 21 and the first radiating branch 11; a second feeding point 211 and a second grounding point 212 are provided on the second radiating branch 21, and the second matching circuit 22 is electrically connected between the second feeding point 211 and the second RF port 23; the second matching circuit 22 includes at least one second electronic component 221.

[0088] The antenna structure in this embodiment arranges two antenna components at the same time, and the first radiating branch node 11 and the second radiating branch node 21 are arranged end to end. By utilizing the second antenna component 2, the antenna structure can achieve coverage of more frequency bands, increase the working modes of the antenna structure, and improve the working bandwidth and working performance of the antenna structure.

[0089] Combination Figure 1 As shown, in some embodiments, the second feeding point 211 is close to the third end 2101 of the second radiation branch 21 , and the second grounding point 212 is located at the fourth end 2102 of the second radiation branch 21 .

[0090] The distance between the third end 2101 and the fourth end 2102 of the second radiation branch 21 is L3, and the distance between the second feeding point 211 and the third end 2101 is L4. The value range of L3 is 16mm-20mm, and the value range of L4 is 4mm-8mm.

[0091] When the relevant dimensions of the second radiation branch 21 meet the above value range, the second antenna component 2 can achieve frequency band coverage of WIFI2.4G and MHB, effectively improving the antenna performance in user handheld and gaming scenarios.

[0092] In some possible implementations, the distance L3 between the third end 2101 and the fourth end 2102 of the second radiation branch 21 is, for example, 16 mm, 16.5 mm, 17 mm, 17.5 mm, 18 mm, 18.5 mm, 19 mm, 19.5 mm, 20 mm, etc. Optionally, the value of L3 is 18 mm.

[0093] In some other possible implementations, the distance L4 between the second feeding point 211 and the third end 2101 is, for example, 4 mm, 4.5 mm, 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, etc. Optionally, the value of L4 is 6 mm.

[0094] In some possible implementations, the width of the fracture structure 3 ranges from 0.6 mm to 1.0 mm. For example, the width of the fracture structure 3 is, for example, 0.6 mm, 0.65 mm, 0.7 mm, 0.75 mm, 0.8 mm, 0.85 mm, 0.9 mm, 0.95 mm, 1.0 mm, etc. Optionally, the width of the fracture structure 3 is equal to 0.8 mm.

[0095] Combination Figure 1As shown, in some embodiments, at least one second electronic component 221 includes a third capacitor 2211, a first inductor 2212 and a second inductor 2213; one end of the third capacitor 2211 is electrically connected to the second feeding point 211, and the other end of the third capacitor 2211 is electrically connected to the first inductor 2212 and the second RF port 23 in sequence; one end of the second inductor 2213 is electrically connected to the second feeding point 211, and the other end of the second inductor 2213 is grounded.

[0096] Through the above arrangement, the second matching circuit 22 can achieve frequency band coverage of WIFI 2.4G and MHB without the help of switching elements, and does not require additional power-consuming devices such as switching elements, thereby reducing the difficulty of designing the antenna structure.

[0097] In some embodiments, the first antenna assembly 1 is used to cover the WIFI6E+N77 / 78 / 79 frequency band, and the second antenna assembly 2 is used to cover the MHB+WIFI2.4G frequency band.

It can be seen from the figure that the frequency band of the first antenna component 1 covers N77 / 78 / 79 and WIFI6E. The highest measured efficiency is -5dB, and the highest gaming efficiency is -8dB, with a decrease of only 3dB. Figure 5 The antenna efficiency of the first antenna component 1 provided in this embodiment is shown. It can be seen from the figure that the frequency band of the second antenna component 2 covers MHB and WIFI2.4G parts. The highest measured efficiency is -4.3dB. The maximum reduction in gaming handheld data is 2dB, and the minimum is basically no reduction.

[0099] It can be seen from the measured data that the antenna structure of the present application can effectively improve the user experience in hand-holding and gaming scenarios while covering multiple frequency bands.
