[0046] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0047] In the description of this 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 drawings. Figure 1 The orientation or positional relationship shown is only for the convenience of describing this 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 this application.

[0048] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those skilled in the art.

[0049] In related technologies, placing the antenna near the phone's buttons (volume and power buttons) fully utilizes the side space of the phone, preventing the antenna from being grasped by one or both hands, and minimizing the degradation of antenna performance. However, due to the specific location of the buttons, there are significant limitations on antenna length, gap location, and clearance width. This results in poor antenna performance, making it difficult to meet the primary radiation performance requirements. The antenna's performance is poor, failing to meet the primary antenna's radiation capacity and internal and carrier standards.

[0050] refer to Figure 1 As shown, it includes a volume button 01 and a power button 02, and the two buttons are arranged at intervals on the side of the mobile phone. Among them, a section of the metal frame corresponding to the volume button 01 serves as a radiating branch 03, and another section of the metal frame corresponding to the power button 02 serves as a parasitic branch 04. The radiating branch 03 and the parasitic branch 04 are separated by a gap, forming an IFA antenna (Inverted-F Antenna) with its head downward. The feeding point 05 needs to be arranged above the mobile phone battery compartment 06. The clearance environment here is poor, and the antenna length is relatively fixed, so there is little room for optimization, so the antenna performance is poor. Therefore, the metal frame corresponding to the power button 02 is constructed as a parasitic branch 04, hoping that the parasitic branch 04 can improve the radiation performance.

[0051] However, long-term practical and theoretical verification have shown that parasitic stub 04 does not have a positive impact on the frame antenna. In fact, the antenna's radiation performance improves significantly when parasitic stub 04 is removed. Removing parasitic stub 04 would create a gap in the metal frame, reducing the overall structural strength and potentially causing the phone to bend.

[0052] This results in the problem that the frame antenna is incompatible with radiation performance and structural strength.

[0053] Therefore, the present application provides a frame antenna and electronic equipment, wherein the frame antenna not only has high structural strength, but also can reduce interference to the antenna body, which is conducive to improving the radiation performance of the antenna body.

[0054] The technical solution provided in this application is applicable to electronic devices that adopt one or more of the following communication technologies: Bluetooth (Blue Tooth, BT) communication technology, Global Positioning System (Global Positioning System, GPS) communication technology, Wireless Fidelity (Wireless Fidelity, WiFi) communication technology, Global System For Mobile Communications (Global System For Mobile Communications, GSM) communication technology, Wideband Code Division Multiple Access (Wideband Code Division Multiple Access, WCDMA) communication technology, Long Term Evolution (Long Term Evolution, LTE) communication technology, 5G communication technology and other future communication technologies.

[0055] The electronic device in the embodiments of the present application may be a mobile phone, a tablet computer, a laptop computer, a smart bracelet, a smart watch, a smart helmet, smart glasses, etc. The electronic device may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, an electronic device in a 5G network, or an electronic device in a future evolved Public Land Mobile Network (PLMN), etc., and the embodiments of the present application are not limited thereto.

[0056] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0057] On the one hand, combined with Figure 2 、 3 As shown, this embodiment provides a frame antenna, which includes: a first frame 1 and a second frame 2.

[0058] The first frame 1 and the second frame 2 are arranged at intervals. The first frame 1 is provided with a first assembly portion 11 for assembling the button 3 , and the second frame 2 is provided with a second assembly portion 21 for assembling the button 3 .

[0059] One of the first frame 1 and the second frame 2 is a metal structure, and the other of the first frame 1 and the second frame 2 includes at least one metal structure segment 22 and at least one non-metal structure segment 23 .

[0060] For example, the first frame 1 is a metal structure, and the second frame 2 is a composite structure of a metal structure segment 22 and a non-metal structure segment 23. Alternatively, the first frame 1 is a composite structure of a metal structure segment 22 and a non-metal structure segment 23, and the second frame 2 is a metal structure.

[0061] As another example, the number of metal structural segments 22 can be one, two, or three, and the number of non-metal structural segments 23 can also be one, two, or three. It is understood that in this embodiment, the number of metal structural segments 22 and non-metal structural segments 23 can be arbitrary, with the goal of forming a composite frame structure with a short current path and high structural strength.

[0062] At least one metal structure segment 22 and at least one non-metal structure segment 23 are connected along the length direction of the first frame 1 or the second frame 2 .

[0063] In the frame antenna of this embodiment, the first frame 1 and the second frame 2 are adjacent to each other, one of which is a metal structure and can serve as the antenna body, and the other is a structure in which metal and non-metal are alternately connected along the length direction. This frame structure not only has high structural strength, but also can use the non-metal part to interrupt the metal part, so that the length of the metal part is reduced. The length of the coupling current that can be generated by the metal part is limited, and the interference to the antenna body is also reduced accordingly, which is conducive to improving the radiation performance of the antenna body.

[0064] Compared to related art solutions, this embodiment designs the metal frame of the first and second frames 1, 2, which does not serve as the antenna body, into a composite structure consisting of a metal structure segment 22 and a non-metallic structure segment 23. The non-metallic structure segment 23 is a non-conductive portion, preventing the antenna body from generating coupling currents in the non-metallic structure during radiation. Furthermore, although the metal structure segment 22 does generate coupling currents during radiation, the metal structure segment 22 is interrupted by the non-metallic structure segment 23, ensuring that the length of the metal structure segment 22 available for the coupling current to flow is sufficient. Interference with the antenna body is minimal, and can be ignored or overcome through simple impedance matching.

[0065] In some possible implementations, the number of frames in the frame antenna includes but is not limited to the first frame 1 and the second frame 2, and may also include a third frame, a fourth frame, etc.

[0066] Exemplarily, one of two adjacent frames includes the aforementioned metal structure segment 22 and non-metal structure segment 23, so that when a frame is used as an antenna body, the adjacent frame cannot generate coupling current that can interfere with it.

[0067] In another exemplary embodiment, when one of the frames is used as the antenna body, all frames adjacent to the frame include the aforementioned metal structure segment 22 and non-metal structure segment 23 .

[0068] Combine Figure 2 As shown, in some embodiments, the number of the metal structure segments 22 is at least two, and at least one non-metal structure segment 23 is connected between two adjacent metal structure segments 22 .

[0069] By arranging at least one non-metallic structure segment 23 between two adjacent metal structure segments 22, the two metal structure segments 22 are insulated and separated. Although the two metal structure segments 22 will generate coupling current when radiated by the antenna body, the coupling current can only flow within their respective metal structure segments 22. The flow length of the coupling current is short, and it cannot cause significant interference to the antenna body.

[0070] Illustratively, a non-metallic structure segment 23 is connected between two adjacent metal structure segments 22, thereby increasing the proportion of the metal structure segment 22 in the length direction of the first frame 1 or the second frame 2 as much as possible, which is conducive to improving the structural strength of the first frame 1 or the second frame 2.

[0071] Combine Figure 2 As shown, in some embodiments, the number of the non-metallic structural segments 23 is at least two, and at least one metal structural segment 22 is connected between two adjacent non-metallic structural segments 23 .

[0072] By arranging at least one metal structure segment 22 between two adjacent non-metal structure segments 23 , a metal structure segment 22 with higher structural strength is added between the two non-metal structure segments 23 . The at least one metal structure segment 22 can compensate for the structural strength of the two non-metal structure segments 23 to a certain extent.

[0073] Illustratively, a metal structure segment 22 is connected between two adjacent non-metal structure segments 23, thereby reducing the proportion of the non-metal structure segment 23 in the length direction of the first frame 1 or the second frame 2 as much as possible, which is conducive to improving the structural strength of the first frame 1 or the second frame 2.

[0074] In some embodiments, a dimension of at least one metal structure segment 22 along the length direction of the first frame 1 or the second frame 2 is less than or equal to a first target value.

[0075] In order to ensure that the coupling current in the metal structure segment 22 does not interfere with the antenna body, the size of the metal structure segment 22 along the length direction of the frame is limited to not exceed the first target value. Only when the size of the metal structure segment 22 is smaller than the first target value will the coupling current not interfere with the antenna structure.

[0076] In some embodiments, the first target value is in the range of 2-5 mm. When the first target value satisfies the above range, the coupling current generated by the metal structure segment 22 will not interfere with the antenna body.

[0077] In some possible implementations, the first target value is, for example, 2 mm, 2.2 mm, 2.4 mm, 2.6 mm, 2.8 mm, 3 mm, 3.2 mm, 3.4 mm, 3.6 mm, 3.8 mm, 4 mm, 4.2 mm, 4.4 mm, 4.6 mm, 4.8 mm, 5 mm, etc. Optionally, the first target value is 3 mm.

[0078] In some other possible implementations, the dimension of the non-metallic structural segment 23 along the length direction of the first frame 1 or the second frame 2 is less than or equal to the third target value. By limiting the dimension of the non-metallic structural segment 23, the problem of insufficient structural strength of the first frame 1 or the second frame 2 due to a large span of the non-metallic structural segment 23 is avoided.

[0079] For example, the third target value is in the range of 2-5 mm. When the third target value satisfies the above range, the presence of the non-metallic structural segment 23 will not adversely affect the structural strength of the second frame 2 or the third frame.

[0080] In some possible implementations, the third target value is, for example, 2 mm, 2.2 mm, 2.4 mm, 2.6 mm, 2.8 mm, 3 mm, 3.2 mm, 3.4 mm, 3.6 mm, 3.8 mm, 4 mm, 4.2 mm, 4.4 mm, 4.6 mm, 4.8 mm, 5 mm, etc. Optionally, the third target value is 3 mm.

[0081] In some embodiments, taking the first frame 1 including a metal structure segment 22 and a non-metal structure segment 23 as an example, the ratio of the sum of the sizes of all the metal structure segments 22 to the total length of the first frame 1 is 50-70%, and the ratio of the sum of the sizes of all the non-metal structure segments 23 to the total length of the first frame 1 is 40-60%.

[0082] Taking the second frame 2 including the metal structure segment 22 and the non-metal structure segment 23 as an example, the ratio of the sum of the sizes of all the metal structure segments 22 to the total length of the second frame 2 is 50-70%, and the ratio of the sum of the sizes of all the non-metal structure segments 23 to the total length of the second frame 2 is 40-60%.

[0083] In some embodiments, when the first frame 1 or the second frame 2, which are metal structures, are in a radiation scenario, the length of the coupled current generated within at least one metal structure segment 22 is less than or equal to a second target value; the second target value is the current length that interferes with the current within the metal structure. By limiting the length of the coupled current within the metal structure segment 22 to less than or equal to the second target value, interference with the antenna body by the metal structure segment 22 can also be prevented. The second target value can be obtained through calculation, experimentation, or other means.

[0084] Combine Figure 2 、 3 As shown, in some embodiments, the second frame 2 includes at least one metal structure segment 22 and at least one non-metal structure segment 23 ; the end of the second assembly portion 21 along the length direction of the second frame 2 is located in the at least one metal structure segment 22 .

[0085] The second frame 2 of this embodiment is a composite frame composed of a metal structure segment 22 and a non-metal structure segment 23. The end of the second assembly portion 21 on the second frame 2 along the length direction is located inside the metal structure segment 22. Since the strength of the metal structure segment 22 is higher than that of the non-metal structure segment 23, the end of the second assembly portion 21 is arranged inside the metal structure segment 22, which can reduce the impact of the second assembly portion 21 on the structural strength.

[0086] Combine Figure 3 As shown, in some embodiments, the second assembly portion 21 includes a first end 211 and a second end 212 along the length direction of the second frame 2; the second frame 2 includes a first metal structure segment 22 and a second metal structure segment 22; the first end 211 is located in one of the metal structure segments 22, and the second end 212 is located in the other metal structure segment 22.

[0087] By arranging the first end 211 and the second end 212 of the second assembly part 21 in the two metal structure segments 22 respectively, the high local strength of the metal structure segment 22 can be fully utilized, thereby reducing the impact of the second assembly part 21 on the overall structural strength of the second frame 2 and improving the overall structural strength of the second frame 2.

[0088] Combine Figure 2 、 3 As shown, in some embodiments, the first frame 1 is a metal structure, and the second frame 2 includes at least one metal structure segment 22 and at least one non-metal structure segment 23; one of the non-metal structure segments 23 is located at the end of the second frame 2 close to the first frame 1, and one of the metal structure segments 22 is located at the end of the second frame 2 away from the first frame 1.

[0089] In this embodiment, the first frame 1 is a metal structure, and the second frame 2 is a composite structure of a metal structure segment 22 and a non-metal structure segment 23. The first frame 1 serves as the antenna body. In order to further reduce the interference of the second frame 2 on the first frame 1 and give full play to the insulation advantage of the non-metal structure segment 23, the end of the second frame 2 close to the first frame 1 is arranged as a non-metal structure segment 23. This makes the metal part of the second frame 2 farther away from the first frame 1, and the first frame 1 can obtain a larger clearance in this area, which is beneficial to improving the radiation performance of the first frame 1.

[0090] On the other hand, the end of the second frame 2 away from the first frame 1 is usually connected to the metal middle frame 100 of the electronic device, and provides strength support for this area. Therefore, this end of the second frame 2 is arranged as a metal structural segment 22 to fully ensure the overall structural strength of the second frame 2.

[0091] Combine Figure 2 、 3As shown, in some embodiments, the non-metallic structural segment 23 is a plastic structure, and the metal structural segment 22 and the non-metallic structural segment 23 are injection molded in sections along the length direction of the second frame 2. The segmented injection molding process can utilize the segmented processing of metal materials and plastic materials to form a composite frame of this embodiment.

[0092] In some possible implementations, the joining surface between the metal structure segment 22 and the non-metal structure segment 23 is non-planar, in order to improve the bite force between the metal structure segment 22 and the non-metal structure segment 23 .

[0093] Optionally, the joining surface between the metal structure segment 22 and the non-metal structure segment 23 is designed to be an arc surface, a serrated surface, a mortise and tenon surface, etc.

[0094] In other possible implementations, the plastic structure is made of plastic materials, including but not limited to PC (polycarbonate), ABS (acrylic-butadiene-styrene copolymer) and PC+ABS, etc. The above plastic materials have the advantages of high strength, non-toxicity, good low-temperature properties, and good processing fluidity, which are conducive to the processing and molding of the non-metallic structural segment 23 and can obtain higher structural strength.

[0095] In some embodiments, button 3 is one or more of the following: a volume button, a power button; the volume button and the power button are the most commonly used types of buttons in electronic devices, and need to be arranged in the side area of ​​the electronic device, that is, on the border of the electronic device. By using the border antenna provided in this application, the border where the volume button and the power button are located can be fully utilized, the utilization rate of the border can be improved, the antenna arrangement capability of the electronic device can be increased, and the wireless communication performance of the electronic device can be improved.

[0096] On the other hand, combined Figure 2 、 3 As shown, this embodiment provides an electronic device, which includes: the border antenna of the present application, and a first button 31 and a second button 32; the first button 31 is located in the first assembly part 11, and the second button 32 is located in the second assembly part 21.

[0097] The electronic device of this embodiment adopts the border antenna of this application and has all the beneficial technical effects of this application.

[0099] Combine Figure 2 、 3As shown, in some embodiments, the metal middle frame 100 includes a frame portion 101 and a middle plate portion 102, and the frame portion 101 is located at the circumferential edge of the middle plate portion 102; the frame portion 101 is at least partially formed into at least one of a first frame 1 and a second frame 2.
