Detailed Implementation

[0041] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0042] In this application, the terms "upper," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0043] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0044] Furthermore, the terms "set up," "equipped with," and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0045] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0046] Currently, electronic devices are evolving towards thinner, lighter designs, narrower bezels, and metallic finishes to offer more functionality and a better user experience. Against this backdrop, the increase in internal functional components in electronic devices has compressed the clearance area for antennas, making antenna design increasingly challenging.

[0047] Conventional IFA and PIFA antennas are primarily fed via metal springs on a circuit board. Their functionality is achieved by adjusting the electrical dimensions and current direction of the antenna within the clearance area, placing higher demands on clearance. Cavity antennas, on the other hand, consist of a semi-enclosed metal cavity, with openings near the frame to achieve the same functionality. Cavity antennas typically feature low profiles and integrability, reducing clearance requirements and meeting the antenna performance requirements of the aforementioned trends towards thinner, narrower bezels, and metallic designs.

[0048] However, in related technologies, cavity antennas typically use a conductor to enclose and form a cavity, and form a slit on the surface of the conductor for radiation. A feed element is placed inside the cavity, and a metal body is further placed on the circuit board inside the electronic device, or a shroud-type metal body is placed on the circuit board and then assembled into the electronic device. These implementation methods require additional metal bodies to form the cavity and then assemble them, which is complex in design, costly, and has the problem of poor assembly consistency.

[0049] Based on this, this application provides an electronic device that forms an antenna cavity by providing an enclosure within a housing, and then sealing part of the cavity with a conductor to create an opening for antenna radiation, effectively forming a cavity antenna. In this way, on the one hand, using a cavity antenna can reduce clearance requirements, which is more conducive to meeting antenna performance requirements in electronic devices that are trending towards thinner, lighter, narrower bezels, and metallic designs; on the other hand, by using the housing itself to form part of the cavity antenna, the structure of the cavity antenna can be simplified, assembly consistency improved, and costs reduced.

[0050] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0051] Please see Figure 1This application discloses an electronic device 100. The electronic device 100 can be any type of device suitable for implementation, including but not limited to tablets, mobile phones, handheld consoles, or laptops. This application does not make specific limitations on this. The following embodiments will use a tablet as an example to illustrate the electronic device 100.

[0052] Please refer to the following: Figures 2 to 5 In some embodiments, the electronic device 100 includes a housing 10, a conductor 20, and a power supply component 30. The housing 10 includes a bottom wall 11 and a side wall 12. The side wall 12 surrounds and connects to the bottom wall 11, forming a cavity 13. A surrounding portion 111 protrudes from the bottom wall 11, forming an antenna cavity 112. The antenna cavity 112 has an opening 112a communicating with the cavity 13. The power supply component 30 is located in the antenna cavity 112 and connected to the bottom wall 11. The conductor 20 is disposed in the cavity 13, connected to the surrounding portion 111, and covers at least a portion of the opening 112a. A slit 112b communicating with the antenna cavity 112 is formed on one side adjacent to the side wall 12. The conductor 20 is connected to the power supply component 30, so that the conductor 20 and the antenna cavity 112 together form an antenna portion 40.

[0053] This application forms an antenna cavity 112 by providing an enclosure 111 within the housing 10, and then sealing part of the antenna cavity 112 with a conductor 20, forming a slot 112b on one side near the sidewall 12. The slot 112b is used to radiate and receive electromagnetic wave energy, and the conductor 20 is used to connect to the feeding component 30 for feeding, thus forming a cavity antenna inside the electronic device 100. In this way, on the one hand, the cavity antenna can reduce the requirements for the clearance environment, which is more conducive to meeting the antenna performance requirements of the electronic device 100 in the trend of thinner, narrower bezels and metallization; on the other hand, by using the housing 10 itself to form part of the cavity antenna, the number of antenna components is reduced. Compared with a cavity antenna separately installed in the housing 10, this application simplifies the structure of the cavity antenna, improves the consistency of assembly, facilitates production and assembly, and reduces production costs.

[0054] It is understood that in this embodiment of the application, the antenna portion 40 formed by the conductor 20 and the antenna cavity 112 is equivalent to a cavity antenna. The conductor 20 covers part of the opening 112a, so the unsealed part forms a slit 112b, through which electromagnetic waves can enter the antenna cavity 112 and the antenna portion 40 from the external space and radiate to the external space.

[0055] Optionally, the bottom wall 11 and side walls 12 of the housing 10 can be integrally formed from all-metal components to create an all-metal body, enhancing the appearance and texture of the electronic device 100. Of course, in other embodiments, the housing 10 can be non-metallic, enabling the electronic device 100 to be lightweight.

[0056] It is worth noting that, typically, when the housing 10 is an all-metal design, its ability to reflect and absorb electromagnetic waves leads to a decrease in antenna radiation efficiency and signal attenuation. When a cavity antenna is constructed internally using the all-metal housing space, the cavity antenna can better adapt to the shielding effect and reduce signal attenuation. Furthermore, since the resonant frequency of the cavity antenna is primarily determined by the size and structure of the antenna cavity 112, the metallized housing 10 has a smaller impact on its frequency shift, thus enabling higher frequency stability for the antenna.

[0057] Combination Figures 1 to 4 In some embodiments, the electronic device 100 includes a display screen 50, which is disposed in the housing 10, connected to the side wall 12, and covers the cavity 13.

[0058] The display screen 50 may include a display area 51 and a bezel area 52. The display area 51 is used to display images, and its back is usually a metal area used for the wiring of the display area 51. The bezel area 52 is also known as the "black border" in the field of electronic devices. This area is usually a non-metallic area and has a weaker shielding effect on antenna signals. For cavity antennas, they are generally placed near this bezel area 52 to ensure that the antenna performance meets the design requirements of the electronic device 100.

[0059] It can be understood that the bezel area 52 is located on the outer periphery of the display area 51, and this bezel area 52 is connected to the side wall 12 of the housing 10. Therefore, the slit 112b is located near the side wall 12, which can also be understood as the slit 112b being located near the bezel area 52. Since the bezel area 52 has a weak shielding effect on antenna signals, the antenna section 40 can better radiate and receive electromagnetic waves through the slit 112b located near the side wall 12.

[0060] In order to make the slit 112b form on the side of the antenna cavity 112 near the side wall 12, in one possible embodiment, the enclosure portion 111 can be formed independently on the bottom wall 11 of the housing 10. That is, the antenna cavity 112 is formed solely by the structure of the enclosure portion 111 itself. The enclosure portion 111 is set close enough to the side wall 12 so that the slit 112b is formed near the side wall 12, thereby making the slit 112b closer to the frame area 52.

[0061] See Figure 6In another possible implementation, the enclosure 111 is connected to at least a portion of the sidewall 12 so that at least a portion of the sidewall 12 and the enclosure 111 together enclose the antenna cavity 112, and the slit 112b is formed between at least a portion of the sidewall 12 and the conductor 20. In other words, the formation of the antenna cavity 112 utilizes part of the structure of the sidewall 12, that is, the sidewall 12 constitutes part of the antenna section 40. This eliminates the need to form an independent enclosure 111 within the cavity 13. Instead, the design of forming a cavity together with the enclosure 111 using part of the sidewall 12 reduces the space occupied by the cavity 13, which is beneficial for the rational arrangement of the space of the housing 10. On the other hand, based on the sidewall 12 forming part of the antenna cavity 112, the slit 112b formed by the closed opening 112a of the conductor 20 also utilizes this part of the sidewall 12, naturally forming a slit 112b adjacent to the sidewall 12, which is more conducive to the formation of the slit 112b, and further makes the structural layout of the antenna cavity 112 more reasonable.

[0062] Preferably, the enclosure 111 is connected to at least a portion of the sidewall 12, and the sidewall 12 forms part of the antenna cavity 112.

[0063] As can be seen from the foregoing, the frame region 52 is connected to the side wall 12, and the side wall 12 forms part of the antenna cavity 112. This also makes it easier for the slot 112b to be formed closer to the frame region 52. Since the frame region 52 has a weaker shielding effect on the antenna signal, this is more conducive to the radiation of the antenna part 40.

[0064] To improve the performance of the antenna section 40, a cavity antenna can be mounted in the frame region 52, with the slot 112b radiating below the frame region 52. Based on this, the projection of the slot 112b can at least partially fall within the projection range of the frame region 52 on a plane parallel to the bottom wall 11. This improves the radiation and reception capabilities of the antenna section 40, thereby enhancing its overall performance.

[0065] This application provides an electronic device 100, which can be designed in a narrow bezel area 52. Utilizing the characteristics of the antenna section 40 described above, by placing the slot 112b of the antenna section 40 below the bezel area 52, the shielding effect on electromagnetic waves is reduced, providing a better radiation environment for the antenna section 40 and improving its radiation efficiency. Furthermore, even in a narrow screen bezel environment, the electronic device 100 can maintain good antenna performance.

[0066] In one example, the projection of the slit 112b can be entirely within the projection range of the border region 52. That is, the width of the slit 112b is less than or equal to the width of the border region 52, and from the front view of the electronic device 100, the slit 112b is completely located below the border region 52 of the display screen 50. This allows for better radiation efficiency of the antenna section 40 and optimizes antenna performance.

[0067] Of course, in another example, the projection of the slot 112b can be partially located within the projection range of the frame region 52, which can also satisfy the design requirements of the electronic device 100 by ensuring that the performance of the antenna section 40 meets the requirements of the electronic device 100.

[0068] Combination Figure 6 In some embodiments, the electronic device 100 further includes a grounding component 60 connected between the conductor 20 and the display screen 50. The grounding component 60 is configured to ground the antenna section 40. By placing the grounding component 60 between the conductor 20 and the display screen 50, the space between the conductor 20 and the display screen 50 can be fully utilized while still achieving grounding, resulting in a more rational overall structural arrangement of the antenna section 40.

[0069] Optionally, the grounding component 60 is disposed near the slot 112b, that is, the grounding component 60 is disposed on the side of the conductor 20 near the slot 112b. By disposing the grounding component 60 near the slot 112b, interference with radiated electromagnetic waves can be reduced, thereby improving the radiation efficiency of the antenna.

[0070] Optionally, the grounding component 60 is arranged along the extending direction of the conductor 20, that is, the grounding component 60 is aligned with the extending direction of the conductor 20. By arranging the grounding component 60 along the extending direction of the conductor 20, that is, by making the grounding component 60 elongated, the impact of internal stress on the display screen 50 can be reduced or avoided while still meeting the grounding design requirements of the antenna section 40.

[0071] Optionally, the grounding component 60 can be conductive foam or soft rubber, etc., and is connected between the conductor 20 and the display screen 50 by adhesive.

[0072] It is worth noting that when the conductor 20 is connected to the enclosure 111 and covers at least part of the opening 112a to form a slit 112b, part of the conductor 20 is connected to the enclosure 111 and is supported by the enclosure 111. However, the side forming the slit 112b is not connected to the enclosure 111, and the conductor 20 in this part does not have sufficient support, or even any support at all. Since electromagnetic waves resonate in the antenna cavity 112 when the antenna section 40 is working, the conductor 20 is prone to deformation during this process, leading to structural instability of the antenna section 40. For example, this affects the electromagnetic field distribution within the antenna cavity 112, distorts the antenna's radiation direction, causes uneven signal coverage, and results in weakened or enhanced signal strength in certain directions, thereby affecting the stability and reliability of the antenna performance.

[0073] Therefore, in some embodiments, please refer to [the relevant documentation]. Figures 3 to 6 The electronic device 100 also includes a support member 70, which is disposed within the antenna cavity 112 and connected between the bottom wall 11 and the conductor 20. The support member 70 is configured to support the conductor 20. By providing the support member 70 between the bottom wall 11 and the conductor 20, the conductor 20 can be effectively supported not only at the connection point with the enclosure portion 111, but also in the suspended portion within the antenna cavity 112. This makes the connection of the conductor 20 more secure and reduces the impact of the conductor 20's stability on antenna performance during antenna operation.

[0074] Optionally, the support member 70 can be a support block, support plate, or support bar, as long as it can effectively support the conductor 20 without affecting the performance of the antenna section 40.

[0075] Combination Figure 5 In some embodiments, the support member 70 is positioned near the slot 112b. On one hand, the mechanical strength of the conductor 20 near the slot 112b is relatively low, making it more prone to deformation. Positioning the support member 70 near the slot 112b enhances the mechanical strength of this area, effectively preventing deformation of the conductor 20 and thus improving the overall structural stability of the conductor 20. On the other hand, since the distribution of the electromagnetic field inside the antenna cavity 112 plays a crucial role in the antenna's radiation performance, improper positioning of the support member 70 may disturb the electromagnetic field distribution within the antenna cavity 112. Therefore, by positioning the support member 70 near the slot 112b, while maximizing its support for the conductor 20, placing the support member 70 as close as possible to the edge of the antenna cavity 112 reduces the impact on the electromagnetic field distribution, thereby more effectively ensuring the stability and reliability of antenna performance.

[0076] Since the support member 70 needs to be connected between the bottom wall 11 and the conductor 20, in some embodiments, to facilitate the connection of the conductor 20, the support member 70 has a protruding hook portion 71 near the opening 112b. The hook portion 71 extends out of the opening 112b to abut against the upper surface 20a of the conductor 20. That is, the support member 70 is provided with a hook portion 71, which extends out of the opening 112b and engages with the conductor 20. When the conductor 20 is not yet fixedly connected to the support member 70 and the enclosure 111, the hook portion 71 abuts against the upper surface 20a of the conductor 20 to achieve pre-fixation of the conductor 20, preventing displacement of the conductor 20 and facilitating the fixed connection of the conductor 20.

[0077] It should be noted that the upper surface 20a of the conductor 20 refers to the surface that faces away from the bottom wall 11 in the thickness direction of the electronic device 100, that is, the surface closer to the side where the display screen 50 is located. When the hook portion 71 abuts against this upper surface 20a, the position of the conductor 20 in the thickness direction of the electronic device 100 can be restricted.

[0078] Combination Figure 6 and Figure 7 In some embodiments, the conductor 20 has a first connection hole 20b near the edge of the slot 112b, and the support member 70 has a second connection hole 70a. The conductor 20 is connected to the support member 70 by fasteners 101 passing through the first connection hole 20b and the second connection hole 70a. By connecting the conductor 20 and the support member 70 with fasteners 101, the connection of the conductor 20 is made more secure and the connection stability of the conductor 20 is improved. At the same time, the support member 70 can serve as an intermediate component for the connection of the conductor 20, avoiding the situation where the conductor 20 is directly connected to the bottom wall 11 of the housing 10. This avoids the situation where the conductor 20 and the housing 10 are short-circuited when the housing 10 is made of metal.

[0079] Continue reading Figure 6 In some embodiments, at least a portion of the support member 70 is pressed against the feed member 30 to fix the feed member 30. By pressing at least a portion of the support member 70 against the feed member 30, the feed member 30 can be fixed while saving space occupied by the support member 70 in the antenna cavity 112 without changing the size of the support member 70.

[0080] Optionally, the support member 70 is provided with a first through hole 70b, the feed component 30 is provided with a second through hole 30a, and the bottom wall 11 is provided with a first connecting post 11a. The first connecting post 11a passes through the second through hole 30a and the first through hole 70b. The support member 70 is connected to the first connecting post 11a by a fastener 101 to achieve connection with the feed component 30 and the bottom wall 11. With the support member 70 partially pressed against the feed component 30, the first connecting post 11a on the bottom wall 11 passes through the second through hole 30a on the feed component 30 and the first through hole 70b on the support member 70, and is then connected to the first connecting post 11a by the fastener 101. This achieves the effect of connecting both the support member 70 and the feed component 30 to the bottom wall 11 of the housing 10 simultaneously by a single fastener 101, realizing structural reuse. This not only saves materials and reduces costs, but also makes the overall structure of the antenna section 40 more compact, maximizing the space utilization of the antenna cavity 112.

[0081] Continue reading Figure 6 and Figure 7 In some embodiments, the bottom wall 11 is provided with a second connecting post 11b, and the second connecting post 11b and the first connecting post 11a are spaced apart along the extension direction of the slot 112b. The support member 70 is provided with a third through hole 70c, and the second connecting post 11b passes through the third through hole 70c. The support member 70 is connected to the second connecting post 11b by a fastener 101 to achieve connection with the bottom wall 11.

[0082] By setting a second connecting post 11b on the bottom wall 11 at intervals along the extension direction of the first connecting post 11a along the slot 112b, and connecting the third through hole 70c through the support member 70 to the fastener 101, the connection position of the support member 70 and the bottom wall 11 is located in the same direction, so that the preload applied to the support member 70 is evenly distributed, reducing local stress concentration and making the connection of the support member 70 more reliable.

[0083] It is worth noting that the extension direction of the slit 112b is the length direction of the slit 112b. Taking the shape of the conductor 20 as a rectangle as an example, the extension direction of the slit 112b can also refer to the length direction of the conductor 20.

[0084] In some embodiments, the power supply component 30 is provided with a fourth through hole 30b, which is diagonally arranged with the third through hole 70c. The bottom wall 11 is provided with a third connecting post 11c, which passes through the fourth through hole 30b. The power supply component 30 is connected to the third connecting post 11c by a fastener 101 to achieve connection with the bottom wall 11.

[0085] By providing a fourth through hole 30b on the power supply component 30, and using the third connecting post 11c on the bottom wall 11 to pass through the fourth through hole 30b and connect with the fastener 101, the connection between the power supply component 30 and the bottom wall 11 is further realized. The fourth through hole 30b and the third through hole 70c are set diagonally, that is, the connection position of the power supply component 30 is set diagonally, so that the fastening force is symmetrically and evenly distributed on the power supply component 30, and the power supply component 30 is not easily deformed, thereby improving the mechanical strength of the connection of the power supply component 30 and the stability of the overall structural connection.

[0086] It is understood that the connecting post on the bottom wall 11 of the housing 10 has holes for the fastener 101 to pass through. The power supply component 30 is connected to the bottom wall 11 by providing a second through hole 30a and a fourth through hole 30b at diagonal positions. These two through holes are fitted onto the connecting post, and then the fastener 101 is used to connect to the connecting post. It is understood that the fastener 101 usually needs sufficient height to connect to the connecting post. However, the power supply component 30 is generally thin. Therefore, after the power supply component 30 is fitted onto the connecting post, the connecting post still protrudes a certain height from the surface of the power supply component 30. Since the support member 70 presses on part of the power supply component 30, this part of the support member 70 has a first through hole 70b. The first connecting post 11a passes through both the first through hole 70b and the second through hole 30a. Thus, the support member 70 compensates for the aforementioned protrusion height. To overcome the defect that the third connecting post 11c passes through the fourth through hole 30b, see [reference needed]. Figure 6 A gasket 102 is also provided between the fastener 101 and the power supply component 30 to compensate for the height of the protrusion, thereby achieving effective fixation of the power supply component 30.

[0087] As described above, the conductor 20 is connected to the enclosure 111. In one example, the conductor 20 and the enclosure 111 can be fixed together by screws. Specifically, the end face of the enclosure 111 is provided with a plurality of screw holes at intervals, and correspondingly, the conductor 20 is also provided with screw holes at the corresponding positions. The screws pass through the conductor 20 and the enclosure 111 to fix them together.

[0088] Further, see Figure 7Two positioning posts 111a are provided on the enclosure portion 111, and correspondingly, positioning holes 23 are provided on the conductor 20. The two positioning posts 111a are located on two opposite short sides of the antenna cavity 112 and are staggered along the length of the antenna cavity 112. In this way, when assembling the conductor 20, one side of the conductor 20 can be aligned first, and then the other side of the conductor 20 can be aligned. Compared with the design where the two positioning posts 111a are symmetrically arranged and both sides of the conductor 20 need to be aligned for assembly at the same time, the assembly is easier and the assembly efficiency can be improved. At the same time, the two positioning posts 111a are roughly located diagonally opposite the antenna cavity 112 formed by the entire enclosure portion 111, which provides a better positioning effect for the conductor 20.

[0089] Of course, in other examples, the conductor 20 and the enclosure 111 can also be fixed by welding, or by pressing, as long as the two can be effectively fixed, this application does not make specific limitations.

[0090] See Figure 7 In some embodiments, a raised layer 113 may also be provided on the bottom wall 11. The raised layer 113 is located in the cavity 13 and extends from the connection between the bottom wall 11 and the side wall 12 to the enclosure portion 111 opposite to the side wall 12. At least part of the feeding component 30 is connected to the raised layer 113 so that there is a gap between part of the feeding component 30 and the bottom wall 11. This allows space to be reserved between the feeding component 30 and the bottom wall 11, so that the connection between the feeding component 30 and the bottom wall 11 can be established during the antenna section 40 debugging process to achieve grounding.

[0091] Optionally, the raised layer 113 can be a protrusion or boss protruding from the bottom wall 11, and the size of the raised layer 113 is approximately the same as that of the power supply component 30.

[0092] In some embodiments, the conductor 20 has a flange 21 at its edge, which extends toward the bottom wall 11 and abuts against the enclosure portion 111, so that the conductor 20 covers part of the outer periphery of the enclosure portion 111. The flange 21 at the edge of the conductor 20 engaging with the outer periphery of the enclosure portion 111 effectively means that a portion of the structure of the conductor 20 covers the outer periphery of the enclosure portion 111, making the connection more robust and thus improving the overall reliability of the antenna section 40.

[0093] Optionally, the conductor 20 can be a metal cover plate. The surface of the conductor 20 is provided with protrusions 22, and elongated grooves are formed on the protrusions 22 at intervals. The design of the conductor 20 as a metal cover plate is simple in structure and easy to manufacture. At the same time, the protrusions 22 and the grooves on them prevent the metal cover plate from being a flat plate, ensuring sufficient structural strength even when the metal cover plate is large in size. This makes the metal cover plate less prone to bending and ensures the effective connection of the conductor 20.

[0094] Of course, in other embodiments, the conductor 20 can also be a copper-clad PCB (Printed Circuit Board), FPC (Flexible Printed Circuit Board), or other metal body. That is, the conductor 20 can be made of metal material or a material with a metal layer coated on its surface, as long as it can be connected to the power supply component 30 to achieve power supply.

[0095] In some embodiments, the conductor 20 has a folded edge 24 on the side adjacent to the slit 112b. This folded edge 24 can be formed by bending and stacking it on the surface of the protrusion 22. In this case, the hook portion 71 of the support member 70 can abut against the folded edge 24, and the upper surface 20a can refer to the side of the folded edge 24 facing the display screen 50. This configuration not only enhances the mechanical strength of the conductor 20, making it less prone to deformation, but also makes the hook portion 71 less prone to deformation after contact with the conductor 20, effectively ensuring the reliability of the contact between the hook portion 71 and the conductor 20.

[0096] In some embodiments, see Figure 7 The power supply component 30 can be a PCB, and the enclosure 111 also has a notch 114 communicating with the antenna cavity 112. The notch 114 is configured to allow the power supply component 30 to have a trace for electrical connection with the circuit board of the electronic device. By using the power supply component 30 as a PCB and setting it in the antenna cavity 112, and utilizing the notch formed in the enclosure 111 for PCB traces, the space inside the antenna cavity 112 is fully utilized, making the overall layout more reasonable.

[0097] Optionally, the aforementioned power supply component 30 can be connected to the conductor 20 via a spring sheet disposed on the PCB surface to achieve power supply. This connection method has a simple structure and is easy to manufacture.

[0098] Furthermore, it is understood that the aforementioned notch 114 can be set according to the specific location of the functional device connected to the PCB. It can be set on the short side of the antenna cavity 112 or on the long side of the antenna cavity 112. The specific location can be selected according to actual needs, and this application embodiment does not limit it.

[0099] Of course, in some other embodiments, the power supply component 30 can be an FPC or other structure that can be connected to the conductor 20 via a coaxial cable, as long as it can satisfy the electrical connection with the conductor 20.

[0100] In antenna design, the internal space of the electronic device 100 and the relationship between the antenna's wavelength and size must be considered to achieve optimal antenna performance. Based on this, in some embodiments, the antenna cavity 112 can be a rectangular cavity, the wavelength of the antenna section 40 is λ, the length of the antenna cavity 112 ranges from 0.4λ to 0.6λ, the width of the antenna cavity 112 ranges from 0.15λ to 0.35λ, and the height of the antenna cavity 112 ranges from 0 to 0.25λ. For example, the length of the antenna cavity 112 can be 0.45λ, 0.5λ, 0.55λ, etc., the width of the antenna cavity 112 can be 0.2λ, 0.25λ, 0.3λ, etc., and the height of the antenna cavity 112 can be 0.1λ, 0.15λ, 0.2λ, etc. By using the above ranges, the relationship between the size of the antenna cavity 112 and the wavelength can be controlled. By selecting an appropriate size range based on the influence of the wavelength, better performance of the antenna section 40 can be achieved.

[0101] That is, the antenna cavity 112 is roughly rectangular in shape, with two opposing short sides and two opposing long sides. As mentioned above, a portion of the structure of the antenna cavity 112 utilizes the sidewall 12 of the housing 10. For example, the antenna cavity 112 utilizes the sidewall 12 to form one of its long sides, making the structure of the antenna cavity 112 more rational. Of course, in other examples, the antenna cavity 112 can also utilize the sidewall 12 to form one of its short sides.

[0102] Furthermore, the antenna cavity 112 has a length of 56mm-60mm, a width of 30mm-32mm, and a height of 2.7mm-2.9mm. By adopting the above-mentioned range, the antenna cavity 112 not only meets the design requirements of the electronic device 100 and achieves the required antenna performance, but also satisfies the actual needs of the electronic device 100 in terms of overall thickness and available space, thus achieving the overall antenna performance of the electronic device 100.

[0103] Optionally, the length of the antenna cavity 112 can be 57mm, 58mm, 59mm, etc., the width of the antenna cavity 112 can be 30.5mm, 31mm, 31.5mm, etc., and the height of the antenna cavity 112 can be 2.75mm, 2.8mm, 2.85mm, etc.

[0104] In some embodiments, the width of the slot 112b can be in the range of 0-0.25λ, for example, it can be 0.1λ, 0.15λ, 0.2λ, etc. By using a slot 112b width in the range of 0-0.25λ, the antenna section 40 can achieve good radiation and reception effects, which is beneficial to improving the radiation efficiency of the antenna section 40, thereby improving the antenna performance.

[0105] Furthermore, the width of the slit 112b can be 3.3mm-3.5mm, for example, 3.35mm, 3.4mm, 3.45mm, etc.

[0106] It should be noted that the length of the aforementioned slot 112b can be determined based on the length of the antenna cavity 112. That is, the slot 112b is not closed, and its length extends from one short side of the antenna cavity 112 to the other short side, having the same length as the antenna cavity 112. In this way, while meeting the design requirements of the slot 112b and satisfying the radiation efficiency of the antenna section 40, the design requirements of the conductor 20 are reduced. It only needs to be shaped to fit the antenna cavity 112 and partially cover the opening 112a.

[0107] Preferably, the length, width, and height of the antenna cavity 112 can be 58mm, 31.5mm, and 2.85mm, respectively, and the width of the slit 112b can be 3.45mm. In this way, while meeting the requirements of the overall thickness of the electronic device 100 and the available internal space, the radiation efficiency of the antenna section 40 can be made higher, thereby optimizing the performance of the antenna section 40.

[0108] Optionally, the first resonant frequency band of the antenna section 40 is 2402MHz-2482MHz, and the second resonant frequency band of the antenna section 40 is 5150MHz-5850MHz. For details, see [link to documentation]. Figure 8 , Figure 8 The diagram shows the reflection coefficient curve (S11 curve) of the antenna section 40 disclosed in this application as a dual-band WiFi antenna. In this figure, the frequency corresponding to the lowest point of the reflection coefficient is the resonant frequency of the antenna section 40. The first resonant frequency can reach 2450MHz, and the second resonant frequency can reach 5500MHz. That is, using the antenna section 40 of this application, the first resonance can cover the operating range of 2402MHz-2482MHz, and the second resonance can cover the operating range of 5150MHz-5850MHz, which improves the overall resonant frequency of the antenna section 40, thereby improving the radiation efficiency of the antenna section 40 and achieving higher antenna performance.

[0109] The location of the feed point affects the resonance offset of the antenna section 40. Therefore, optionally, the feed point of the feed component 30 is located near the slot 112b, that is, the position where the feed component 30 is connected to the conductor 20 should be as close as possible to the slot 112b. In this way, the impact on the resonant frequency can be reduced, resulting in better radiation performance of the antenna section 40.

[0110] The above provides a detailed description of the electronic devices disclosed in the embodiments of this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the electronic devices and their core ideas. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
