[0040] The embodiments of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0041] Currently, full-screen or curved screens are a mainstream development trend in electronic devices. However, the full-screen or curved screen design of electronic devices contradicts the requirement that the area around the antenna should be made of non-metallic materials to achieve better radiation performance.

[0042] Conventional antennas require a 4mm-5mm clearance space on the outside of the display screen for placement. If the antenna is placed on the back or directly below the display screen without clearance, its performance and field pattern will be greatly limited and affected. Therefore, antenna design is a significant challenge in mobile terminal products with high screen-to-body ratios.

[0043] Moreover, for electronic devices with extreme aesthetic requirements such as full-screen, curved screen, or foldable full-screen displays, antennas cannot be placed in the rotating connection structure of the electronic device. Generally, the antenna is placed in the two parts of the electronic device's housing that can rotate or fold relative to each other. The metal environment inside the electronic device's housing will affect the communication performance of the electronic device.

[0044] To address the aforementioned issues, the electronic device provided in this application incorporates a first antenna within a first body, with its feed terminal connected to a first conductive frame of the first body. This allows the first antenna to transmit signals using the first conductive frame with a first gap in a first operating mode, and to transmit signals using both the first and second conductive frames in a second operating mode. This enables the first antenna to utilize the conductive frames within the electronic device for signal transmission, improving its communication performance. Furthermore, the first antenna can transmit signals using either the first conductive frame or both the first and second conductive frames depending on the operating mode, ensuring good communication performance for the first antenna regardless of the electronic device's orientation.

[0045] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0046] refer to Figure 1 and Figure 2 As shown, Figure 1This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application when the first antenna is in a first operating mode. Figure 2 A schematic diagram of an electronic device provided in this application, showing the first antenna in a second operating mode, is shown. The electronic device includes:

[0047] A first body 11 and a second body 12 that can be bent relative to each other, the periphery of the first body 11 has a first conductive frame 111, the periphery of the second body 12 has a second conductive frame 121, and the first conductive frame 111 has a first gap 01.

[0048] The first antenna 21 is located inside the first body 11, and the feed terminal 22 of the first antenna 21 is connected to the first conductive frame 111.

[0049] The first antenna 21 has a first operating mode and a second operating mode; in the first operating mode, the first antenna 21 transmits signals based on the first conductive frame 111 having a first gap 01; in the second operating mode, the first antenna 21 transmits signals based on the first conductive frame 111 and the second conductive frame 121.

[0050] The electronic device has a first antenna 21 housed within a first body 11, and the feed terminal 22 of the first antenna 21 is connected to a first conductive frame 111 of the first body 11. Thus, the first antenna 21 can transmit signals using the first conductive frame 111 with a first gap 01 in a first operating mode, and can transmit signals using both the first conductive frame 111 and the second conductive frame 121 in a second operating mode. This allows the first antenna 21 to utilize the conductive frames within the electronic device for signal transmission, improving its communication performance. Furthermore, the first antenna 21 can transmit signals using either the first conductive frame 111 or both the first conductive frame 111 and the second conductive frame 121, depending on the operating mode, ensuring good communication performance for the first antenna 21 regardless of the electronic device's orientation.

[0051] The first gap 01 can disconnect the first conductive frame 111. When the first antenna 12 is in the first operating mode, the first antenna 21 transmits signals based on the first conductive frame 111 with the first gap connected to the feed terminal 22. When the first antenna 21 is in the second operating mode, the first antenna 21 transmits signals based on the first conductive frame 111 with the first gap connected to the feed terminal 22, and the second conductive frame 121 coupled to the first conductive frame 111.

[0052] In the first working mode, such as Figure 1As shown, the relative positions of the first body 11 and the second body 12 do not satisfy the positional relationship, and the first conductive frame 111 and the second conductive frame 121 do not satisfy the coupling relationship. At this time, the second conductive frame 121 has no effect or a very small effect on the signal transmission of the first antenna 21, and the first antenna 21 can transmit signals based on the first conductive frame 111.

[0053] In the second working mode, such as Figure 2 As shown, the relative positions of the first body 111 and the second body 121 satisfy the positional relationship, and the first conductive frame 111 and the second conductive frame 121 satisfy the coupling relationship. At this time, the second conductive frame 121 can be coupled with the first conductive frame 111, so that the first antenna 21 can transmit signals based on the first conductive frame 111 and the second conductive frame 121.

[0054] Based on the above description, in the electronic device described in this application embodiment, if the relative positional relationship between the first body 11 and the second body 12 does not satisfy the positional relationship, the first conductive frame 111 and the second conductive frame 121 do not satisfy the coupling condition, and the first antenna 21 is in the first working mode; if the relative positional relationship between the first body 11 and the second body 12 satisfies the positional relationship, the first conductive frame 111 and the second conductive frame 121 satisfy the coupling condition, and the first antenna 21 is in the second working mode.

[0055] The first body 11 and the second body 12 are connected by a connecting portion 13, which allows the first body 11 and the second body 12 to be bent relative to each other. The connecting portion 13 is a flexible structure, such as being part of a flexible display screen, and can be bent. In other cases, the connecting portion 13 can also be a mechanical rotating structure, such as a pivot or a hinge.

[0056] In this embodiment, the positional relationship between the first body 11 and the second body 12 can be determined based on the distance between their corresponding predetermined positions. If the distance is greater than a preset distance threshold, the positional relationship is not satisfied; otherwise, the preset relationship is satisfied. When the distance is less than the distance threshold, a coupling gap is formed between the first conductive frame 111 and the second conductive frame 121, enabling the antenna to transmit signals. This coupling allows the first conductive frame 111 and the second conductive frame 121 to couple, and the first antenna 21 operates in a second mode, transmitting signals based on the first conductive frame 111 and the second conductive frame 121, thus improving the performance of the first antenna 21. When the distance is not less than the distance threshold, a coupling gap cannot be formed between the first conductive frame 111 and the second conductive frame 121, and the first antenna 21 operates in a first mode, transmitting signals based on the first conductive frame 111.

[0057] The first body 11 can be positioned at its free end, and the second body 12 can be positioned at its free end. The free end of the first body 11 is the end of the first body 11 furthest from the connecting portion 13, and the free end of the second body 12 is the end of the second body 12 furthest from the connecting portion 13. In this case, if the distance between the free ends of the first body 11 and the second body 12 is greater than a preset distance threshold, the positional relationship is not satisfied; if the distance is not greater than the distance threshold, the positional relationship is satisfied. The distance threshold can be set based on the size of the electronic device and the position of the first body 11 within its body; for example, the distance threshold can be set to be no less than 30mm.

[0058] It should be noted that if the positional relationship is satisfied based on the distance between the first body 11 and the second body 12 at a predetermined position, the orientation of the electronic device is not limited when the first antenna 21 is in the first working mode. Figure 1 The first body 11 and the second body 12 are in a flattened state. When the distance between the first body 11 and the second body 12 at a predetermined position is greater than the distance threshold, the first antenna 21 is in the first operating mode regardless of the orientation of the electronic device. Similarly, when the first antenna 21 is in the second operating mode, the orientation of the electronic device is not limited to... Figure 2 The first body 11 and the second body 12 are in a relatively parallel bent state. When the distance between the first body 11 and the second body 12 at a set position is not greater than the distance threshold, the first antenna 21 is in the second working mode in any posture corresponding to the electronic device.

[0059] A distance sensor can be integrated on the first body 11 or the second body 12 to detect the distance between the first body 11 and the second body 12 at a set position, in order to determine whether the first body 11 and the second body 12 satisfy the positional relationship.

[0060] Obviously, when determining whether the first body 11 and the second body 12 satisfy the positional relationship based on distance information, the set position is not limited to the free ends of the first body 11 and the second body 12. It can also be determined based on the distance between other positions of the first body 11 and the second body 12, for example, based on... Figure 1 The distance between the midpoint of the left short side of the first conductive frame 111 and the midpoint of the left short side of the second conductive frame 121 is used to determine whether the first body 11 and the second body 12 satisfy the positional relationship.

[0061] The positional relationship between the first body 11 and the second body 12 can also be determined based on the included angle between them. If the included angle is within a set angle range, the positional relationship is not satisfied; otherwise, the preset relationship is satisfied. This angle range is set as (A1, A2), where A1 and A2 are both set angle values, A1 is less than A2, and A1 is greater than 0°, while A2 is less than 360°. If a ∈ (A1, A2), the first body 11 and the second body 12 do not satisfy the positional relationship; if a ∉ (A1, A2), the first body 11 and the second body 12 satisfy the positional relationship.

[0062] When a∉(A1, A2), 0°≤a≤A1, or A2≤a≤360°, a coupling gap can be formed between the first conductive frame 111 and the second conductive frame 121 to couple the antenna transmission signal. This coupling allows the first antenna 21 to operate in a second mode, enabling it to transmit signals based on the first conductive frame 111 and the second conductive frame 121, thus improving its performance. When a∉(A1, A2), A1<a<A2, a coupling gap cannot be formed between the first conductive frame 111 and the second conductive frame 121, and the first antenna 21 operates in a first mode, transmitting signals based on the first conductive frame 111.

[0063] An angle sensor can be integrated on the first body 11 or the second body 12 to detect the included angle between the first body 11 and the second body 12, and to determine whether the first body 11 and the second body 12 satisfy the positional relationship.

[0064] refer to Figure 3 and Figure 4 As shown, Figure 3 This is a schematic diagram of the structure of another electronic device provided in an embodiment of this application when the first antenna is in a first operating mode. Figure 4 This is a schematic diagram of another electronic device provided in an embodiment of this application when the first antenna is in a second operating mode. Figure 1 The method shown is the same. Figure 3 This is a top view of the electronic device when the first antenna 21 is in the first operating mode, and... Figure 2 The method shown is the same. Figure 4 This is a side view of the electronic device corresponding to the side of the first antenna 21 when the first antenna 21 is in the second operating mode. Figure 1 and Figure 2 The difference is that, Figure 3 and Figure 4 In the illustrated configuration, the second conductive frame 121 includes a second gap 02.

[0065] and Figure 1 The method shown is the same. Figure 3 In the illustrated configuration, when the first antenna 21 is in the first operating mode, the first antenna 21 transmits signals based on the first conductive frame 111 with a first gap 01 connected to the feed terminal 22. At this time, although the second conductive frame 121 has a second gap 02, since the second conductive frame 121 and the first conductive frame 111 do not satisfy the coupling condition, the second gap 02 has no effect on the signal transmission of the first antenna 21.

[0066] and Figure 2 The methods shown are different. Figure 4 In the illustrated configuration, when the second antenna 21 is in the second operating mode, the first antenna 21 transmits signals based on a first conductive frame 111 with a first gap 01 and a second conductive frame 121 with a second gap 02. At this time, the first conductive frame 111 and the second conductive frame 121 satisfy the coupling condition, and the first antenna 21 transmits signals based on the first conductive frame 111 with the first gap 01 and the second conductive frame 121 with the second gap 02 connected to the feed terminal 22.

[0067] exist Figure 4 In the illustrated configuration, when the first antenna 21 is in the second operating mode, the first conductive frame 121 and the first conductive frame 111 satisfy the coupling condition. At this time, the second gap 02 on the second conductive frame 121 can change the metallic environment of the first antenna in this operating mode, thereby adjusting the performance of the first antenna 21 in the second operating mode.

[0068] like Figure 3 As shown, the first gap 01 and the second gap 02 can be configured symmetrically when the electronic device is in a flattened position. Obviously, the first gap 01 and the second gap 02 can also be configured asymmetrically when the electronic device is in a flattened position. In this embodiment, the specific positions of the first gap 01 and the second gap 02 are not limited. The position of the first gap 01 in the first conductive frame 111 and the position of the second gap 02 in the second conductive frame 121 can be adjusted according to requirements to ensure that the first antenna 21 has good antenna performance in both the first and second operating modes.

[0069] To ensure the integrity of the electronic device's appearance, the first gap 01 is filled with insulating material. Similarly, when the second gap 02 is present, to ensure the integrity of the electronic device's appearance, the second gap 02 is filled with insulating material.

[0070] In the embodiments of this application, it can be as follows: Figures 1-4 As shown, the same first antenna 21 has a first gap 01 set on the first conductive frame 111.

[0071] Alternatively, the first antenna 21 can be configured with two first slots 01 corresponding to the first conductive frame 111, and the feed terminal 22 of the first antenna 21 can be connected to the first conductive frame 111 between the two corresponding first slots 01. The two first slots 01 corresponding to the first antenna 21 can be located on the same side or two adjacent sides of the first conductive frame 111. When one first antenna 21 is configured with two first slots 01, if a second slot 02 is configured on the second conductive frame 121, the second slot 02 can be one or more.

[0072] like Figure 1 and Figure 3 As shown, the first antenna 21 includes a microstrip line 211. The shape of the microstrip line 211 is not limited to... Figure 1 and Figure 3 The L-shape shown can also be T-shaped or straight, etc. The specific shape of the microstrip line 211 is not limited in this embodiment. One end of the microstrip line 211 is connected to the feed terminal 22, and the other end is floating, making that end open-circuited, which is used to increase the electrical length of the first antenna 21, thereby achieving stronger radiation performance in a limited wiring space.

[0073] correspond Figure 1 and Figure 2 As shown, when the first antenna 21 is in the first operating mode, the equivalent antenna system in the electronic device can be as follows: Figure 5 As shown.

[0074] refer to Figure 5 As shown, Figure 5 This application provides a schematic diagram of an antenna system in an electronic device with a first antenna in a first operating mode, in conjunction with... Figure 1 , Figure 2 as well as Figure 5 As shown, in the first operating mode, the microstrip line 211 of the first antenna 21 is connected to the first conductive frame 111 through the feed terminal 22, and is also connected to the grounding component in the first body 11. The grounding component in the first body 11 includes the metal ground of the circuit board 33 in the first body 11.

[0075] correspond Figure 1 and Figure 2 As shown, when the first antenna 21 is in the second operating mode, the equivalent antenna system in the electronic device can be as follows: Figure 6 As shown.

[0076] refer to Figure 6 As shown, Figure 6 This application provides a schematic diagram of an antenna system in which the first antenna in an electronic device operates in a second mode, in conjunction with... Figure 1 , Figure 2 as well as Figure 6 As shown, in the second operating mode, the microstrip line 211 of the first antenna 21 is connected to the first conductive frame 111 through the feed terminal 22 and to the grounding component in the first body 11. The relative positional relationship between the first body 11 and the second body 12 results in a coupling gap between the first conductive frame 111 and the second conductive frame 121. When the relative positional relationship between the first body 11 and the second body 12 satisfies the aforementioned positional relationship, the first conductive frame 111 and the second conductive frame 121 satisfy the aforementioned coupling condition.

[0077] for Figure 3 and Figure 4 As shown, when the first antenna 21 is in the first operating mode, the equivalent antenna system in the electronic device is... Figure 1 and Figure 2 The method shown is the same, and so on. Figure 5 As shown, the embodiments in this application will not be described in detail.

[0078] for Figure 3 and Figure 4 As shown, when the first antenna 21 is in the second operating mode, the equivalent antenna system in the electronic device can be as follows: Figure 7 As shown.

[0079] refer to Figure 7 As shown, Figure 7 This is a schematic diagram of an antenna system in a second operating mode for a first antenna in another electronic device provided in an embodiment of this application, combined with... Figure 3 , Figure 4 as well as Figure 7 As shown, at this time, the second conductive frame 121 has a second gap 02; when the first antenna 21 is in the second working mode, the microstrip line 211 is connected to the first conductive frame 111 through the feed terminal 22 and connected to the grounding component in the first body 11. The relative positional relationship between the first body 11 and the second body 12 results in a coupling gap between the first conductive frame 111 and the second conductive frame 121 with the second gap 02.

[0080] and Figure 6 The antenna system shown differs in that, Figure 7 In the antenna system shown, due to the addition of a second gap 02 in the second conductive frame 121, when the first antenna 21 is in the second operating mode, the metallic environment of the first conductive frame 111 and the second conductive frame 121 changes, resulting in different signal coupling performance and thus different performance parameters of the antenna system.

[0081] refer to Figure 8 As shown, Figure 8 This is a cross-sectional view of a first body in an electronic device provided in an embodiment of this application. Figure 8 The cut surface is perpendicular to Figure 1 and Figure 3 The diagram shows cross-sectional views of the left and right sides of the first body 11 in the electronic device, with the cross-sections passing through the power supply terminal 22.

[0082] Combination Figure 1 , Figure 3 and Figure 8 As shown, the first body 11 includes: a display component 31; a metal frame 32 located away from the display side of the display component 31; a circuit board 33 located on the side of the metal frame 32 away from the display component 31; and a first antenna 21 disposed on the circuit board 33. The first antenna 21 includes a microstrip line 211 and an antenna circuit connected to the microstrip line 211. The ground terminal of the antenna circuit is connected to the metal ground in the circuit board 33, and the metal ground is connected to the metal frame 33.

[0083] Both the antenna circuit and the microstrip line 211 are mounted on the circuit board 33. The circuit board 33 can be a PCB. The antenna circuit is not shown in the accompanying drawings of this embodiment. The antenna circuit can be a conventional antenna circuit, and will not be described in detail in this embodiment.

[0084] Optionally, the feed terminal 22 is disposed on the side of the circuit board 33 facing the connected first conductive frame 111, or on the front of the circuit board 33 facing the display assembly 31. The feed terminal 22 can be connected to the first conductive frame 111 via a spring or a pin. The feed terminal 22 is used to feed radio frequency signals and is connected to the first conductive frame 111 having a first gap 01. The antenna circuit is connected to the feed terminal 22 via a feed wire, and then connected to the microstrip line 211.

[0085] The first antenna 21 includes an antenna body connected to a microstrip line 211. The microstrip line 211 extends the electrical length of the first antenna 21 and couples mid-to-high frequencies, enabling the first antenna 21 to cover the entire WLAN frequency band. The antenna body can be a metal structure fabricated using laser direct forming (LDS) technology or an FPC. The antenna body and the microstrip line 211 are disposed on the back of the circuit board 33 away from the display component 31 to increase the clearance distance with the display component 31.

[0086] In this embodiment, the first conductive frame 111 and the metal frame 32 can be an integral structure or a separate structure.

[0087] Optionally, the first body 11 includes a touch component 35 located on the display side of the display component 31; the area of ​​the metal ground plane opposite to the microstrip line 211 in the circuit board 33 is hollowed out, and there is a gap d between the metal frame 32 and the sidewall of the first conductive frame 111 connected to the feed terminal 22. The hollowing out of the area of ​​the metal ground plane opposite to the microstrip line 211 allows a clear area to be formed in the area of ​​the circuit board 33 where the metal ground plane and the microstrip line 211 are opposite. To ensure the flatness of the metal frame 33, an insulating medium 34 is filled in the gap d, and the insulating medium 34 can be plastic. In other ways, the gap d can be a void gap.

[0088] The metal frame 32 and the sidewall of the first conductive frame 111 connected to the feed terminal 22 have a distance d between them, which allows the area of ​​the metal frame 32 opposite to the microstrip line 211 to form a clearance area. In this way, the clearance distance of the first antenna 21 towards the touch component 35 can be increased, and the touch component 35 can be used as the reference ground of the first antenna 21.

[0089] In this embodiment, the feed terminal 22 of the first antenna 21 is connected to the first conductive frame 111 with a first gap 01, which allows the first conductive frame 111 to serve as the radiator of the first antenna 21, thus improving the performance of the first antenna 21. Furthermore, the area in the circuit board 33 opposite the metal ground plane and the microstrip line 211 is hollowed out, and there is a distance d between the metal frame 32 and the sidewall of the first conductive frame 111 connected to the feed terminal 22. This changes the reference ground of the first antenna 21, not only moving the first antenna 21 away from the metal ground plane and the metal frame 32, increasing its clearance, but also allowing the touch component 35 to serve as the reference ground of the first antenna 21, significantly improving its performance.

[0090] In this embodiment, the first antenna 21 includes a microstrip line 211 on the circuit board 33. On the one hand, the electrical length of the first antenna 21 can be increased based on the coupling between the microstrip line 211 and the first slot 01. On the other hand, the microstrip lines 211 can be coupled to each other. In the first operating mode, the microstrip line 211 can couple with the first slot 01 to generate a portion of mid-to-high frequencies. Moreover, in the second operating mode, based on the relative positional relationship between the two conductive frames, the microstrip line 211 generates a new coupling with the conductive frame, thereby increasing the anti-interference performance. In the second operating mode, based on its coupling relationship with the first conductive frame 111, interference from the second conductive frame 211 to the first antenna 21 is avoided.

[0091] refer to Figure 9 and Figure 10 As shown, Figure 9 A schematic diagram of the structure of another electronic device provided in this application when the first antenna is in a first operating mode. Figure 10 for Figure 9 A cross-sectional view of the first body in the electronic device shown. Figure 10 The cut surface is perpendicular to Figure 9 The diagram shows a cross-sectional view of the left and right sides of the first body 11 in the illustrated electronic device, with the cross-section passing through the feed terminals 22 of the two first antennas 21. In this configuration, the first body 11 contains two first antennas 21, serving as a main antenna and a secondary antenna of the same type, respectively. The feed terminals 22 corresponding to the two first antennas 21 are located on opposite first conductive frames 111 of the first body 11, and the two feed terminals 22 are symmetrically arranged about the centerline of the upper side of the first body 11. When the first antennas 21 are in a second operating mode, the orientation of the electronic device and the coupling method of the first conductive frame 111 and the second conductive frame 121 are similar to those in the above embodiment, and will not be separately illustrated in this embodiment.

[0092] For example, in Figure 9In the illustrated configuration, the two first antennas 21 are located on opposite sides of the upper side of the first body 11, on the left and right first conductive frames 111, respectively. The feed terminals 22 of the two first antennas 21 are symmetrically arranged about the centerline of the upper side of the first body 11. The graphic structure of the two first antennas 21 can be symmetrical about this centerline or it can be an asymmetrical structure.

[0093] When there are two first antennas 21, the feed terminals 22 of the two first antennas 21 can also be set at the first conductive frame 111 corresponding to the side of the first body 11 away from the connecting part 13. At this time, the two feed terminals 22 are also symmetrical about the center line of the side.

[0094] In this embodiment of the application, when there are two first antennas 21, the arrangement of the feed terminals 22 of the two first antennas 21 can be set according to requirements, and can be symmetrically arranged on opposite side walls of the first conductive frame 111 (e.g., Figure 9 The left and right side walls of the first conductive frame 111), and these side walls are located on opposite sides of the connecting portion 13, or the feed terminals 22 of the two first antennas 21 are symmetrically arranged on the same side wall of the first conductive frame 111 away from the connecting portion 13 (e.g., Figure 9 The upper sidewall of the first conductive frame 111 in this application embodiment is not specifically limited in this respect, and can be laid out according to actual needs.

[0095] exist Figure 9 In the illustrated manner, in order to enable the first antenna 21 to have different coupling methods in the second working mode, the second conductive frame 121 can also be configured to have a second gap 02. Each first antenna 21 can be configured with one or more second gaps 02 corresponding to the second conductive frame 121. The configuration scheme of the second gap 02 is the same as that in the above embodiment, and will not be described again in this application embodiment.

[0096] refer to Figure 11 As shown, Figure 11 This application provides a schematic diagram of the structure of an electronic device with two different types of antennas, based on any of the above embodiments. Figure 11 The illustrated configuration also includes a second antenna 41. The first antenna 21 and the second antenna 41 are two different types of antennas, with different radiation frequency bands. For example, one can be a WIFI antenna, and the other can be a WWAN 5G antenna. The antenna types of the first antenna 21 and the second antenna 41 in this embodiment are not specifically limited, and are not limited to the antenna types exemplified in this embodiment.

[0097] exist Figure 11In the illustrated configuration, the second antenna 41 is located within the second body 12, and its feed terminal 22 is connected to the second conductive frame 121. When the first body 11 and the second body 12 satisfy the positional relationship, the microstrip line 211 in the first antenna 21 and the microstrip line in the second antenna 41 do not overlap, so as to avoid the isolation effect caused by the two different types of antennas.

[0098] refer to Figure 12 As shown, Figure 12 This application provides a schematic diagram of the structure of another electronic device with two different types of antennas, as described in the embodiments of this application. Figure 11 The difference is that, Figure 12 In the illustrated configuration, the first antenna 41 is located within the first body 12, and its feed terminal 42 is connected to the first conductive frame 111. The feed terminal 22 connected to the first antenna 21 and the feed terminal 42 connected to the second antenna 41 are respectively located on the first conductive frame 111 corresponding to different sides of the first body 11.

[0099] like Figure 11 and Figure 12 As shown, when a second antenna 42 is included, the conductive frame connected to its feed terminal 42 is provided with a third slot 43 for coupling with the microstrip line in the second antenna 41. The structural design of the second antenna 42 can refer to that of the first antenna 41, and will not be described again in this embodiment.

[0100] In the electronic device described in this application embodiment, when there are two different types of antennas, if the two different types of antennas are simultaneously arranged in the first body 11, the feed terminals of the two different types of antennas are connected to the first conductive frame 111 corresponding to different sides of the first body 11.

[0101] The electronic device can simultaneously be equipped with a Wi-Fi antenna and a WWAN 5G antenna. Specifically, the Wi-Fi antenna includes two first antennas 21, which can serve as the main antenna and the secondary antenna of the Wi-Fi antenna, respectively, based on... Figure 12 The rectangular first body 11 shown has two feed terminals 22 of the first antennas 21 in the WIFI antenna, which can be respectively connected to the short sidewalls on the left and right sides of the first conductive frame 11. The feed terminals of the WWAN 5G antenna are... Figure 12 The long sidewalls on the upper side of the first conductive frame 11 are connected, which can enhance the performance of the two antennas and avoid the isolation problem caused by the close proximity of two different types of antennas. In other ways, the feed terminals 22 of the two first antennas 21 in the WIFI antenna can be connected to the long sidewalls on the upper side of the first conductive frame 11 at the same time, and the feed terminal of the WWAN 5G antenna can be connected to one of the short sidewalls on the left and right sides of the first conductive frame 11.

[0102] In this embodiment, the electronic device can be a laptop computer, with the first body 11 and the second body 12 being the laptop's display screen and keyboard body, respectively. Alternatively, the electronic device can be a flexible display device, with both the first body and the second body having display functionality.

[0103] As can be seen from the above description, the design scheme of the first antenna 21 using the technical solution of this application can achieve at least the following effects:

[0104] First, the reference ground of the first antenna 21 can be changed from the metal back cover 36 of the electronic device to the touch component 35, thereby effectively increasing the effective height of the first antenna 21. The metal back cover 36 is located on the side of the metal frame 33 facing away from the display component 31.

[0105] Second, by setting the gap d, it is equivalent to increasing the distance between the antenna radiator and the metal frame 32, which can greatly improve the efficiency of the first antenna 21.

[0106] Third, the first antenna 21 includes a microstrip line 211 on the circuit board 33. Based on the mutual coupling between the microstrip line 211 and the first slot 01, the electrical length of the first antenna 21 can be increased, and the communication bandwidth of the first antenna 21 can be improved. In the second operating mode, the different relative positions of the two conductive frames cause the first antenna 21 to generate coupling different from that in the first operating mode. The coupling method in the second operating mode generates a new bandwidth and can also enhance anti-interference capabilities.

[0107] Fourth, a multi-input multi-output antenna structure (such as a 2*2 MIMO antenna) can be realized by using two first antennas 21 symmetrically arranged in the feed terminal 22 of the first body 11. This can enhance the antenna throughput to a certain extent and make the antenna communication capability more stable.

[0108] Fifth, by designing the gap positions and filling structures in the conductive frame, electronic devices can have a beautiful appearance, enhancing their market competitiveness.
