Description

laptop Technical Field

[0001] The present application relates to the field of terminal device technology, and more particularly to a laptop computer. This application claims priority to Chinese patent application number 202311867372.X, filed with the State Intellectual Property Office of China on December 29, 2023, entitled “Laptop Computer,” the entire contents of which are incorporated herein by reference. Background Art

[0002] With the advancement of technology, consumers are increasingly demanding the appearance of electronic devices, such as laptops. Laptops, also known as portable computers, handheld computers, PDAs, or laptops, are characterized by their compact size and portability compared to desktop computers. As an everyday office device, laptops are increasingly demanding features like narrow bezels, a full metal finish, and a high-quality feel.

[0003] Since laptops typically require RF antennas, the structural design of narrow-frame, all-metal laptops presents significant challenges in the RF antenna field. For all-metal laptops, there are two common antenna designs: the first involves creating a window in the metal casing on the screen or system side to allow for antenna radiation; the second involves integrating the antenna into the plastic hinge cover.

[0004] However, for narrow-bezel laptops, the first solution would compromise the integrity of the metal and reduce the overall metal feel. While the second solution would still meet the requirements of an all-metal laptop design, it would create a plastic space below the screen, preventing a narrower bezel. Furthermore, this solution typically requires a hinge cover with a large radius, impacting the product's appearance and hindering its all-metal design. Summary of the Invention

[0005] The embodiment of the present application provides a laptop computer, which can greatly reduce the impact of the antenna on the all-metal texture of the laptop computer and is conducive to the design of a narrow frame of the laptop computer.

[0006] An embodiment of the present application provides a laptop computer, comprising: a display and a host computer, one side of the display being hinged to a side of the host computer, characterized in that the host computer comprises: a first metal shell, a heat sink, and an antenna assembly, the heat sink and the antenna assembly being both disposed within the first metal shell, the antenna assembly comprising: an antenna bracket, an excitation source, a grounding region, a feeding point, and a flexible conductive member, a first vent being defined on a side of the first metal shell, the antenna bracket forming at least one ventilation channel, the ventilation channel being disposed opposite and adjacent to the first vent, the antenna bracket having a first surface facing the display and a second surface facing away from the display, the excitation source and the feeding point being disposed on the second surface of the antenna bracket, the feeding point being connected to the excitation source, a grounding region being defined at least on the second surface of the antenna bracket, the excitation source being connected to the grounding region, the flexible conductive member connecting the grounding region and the first metal shell, and the flexible conductive member being located on a side of the excitation source away from the first vent, and a radiation port or a non-metallic member being disposed in an area of ​​the first metal shell facing the excitation source.

[0007] The laptop computer provided in the embodiments of the present application, by positioning the antenna assembly at the first vent of the main body, eliminates the need for the antenna assembly to occupy space on the display side, thereby achieving a narrow-frame, full-screen, and fully metalized design. It also eliminates the need for other internal space within the main body, enhancing the laptop's aesthetics. Furthermore, the excitation source is located on the side of the antenna bracket facing the D-shell (which can be understood as the side of the antenna bracket facing the table when the laptop is placed on a desk), facilitating the fully metalized design of the C-shell and improving the laptop's aesthetics. Furthermore, in actual use, the C-shell typically comprises a cover with a folded edge that snaps onto the D-shell, and the fully metalized C-shell design improves the overall strength of the C-shell. Furthermore, the flexible conductive member is located on the side of the excitation source facing away from the first vent. This shields the excitation source from signal interference within the laptop body and blocks electromagnetic noise. Compared to arrangements in which the excitation source is located on the side of the antenna bracket facing either the first vent or the second vent, this eliminates the need for metal barriers to shield the excitation source from signal interference, contributing to a lighter and thinner laptop computer. At the same time, the radiation surface of the excitation source faces the D shell, and a radiation port or non-metallic parts are provided in the area corresponding to the excitation source on the D shell. There is no need to provide a plastic outer frame as the appearance surface of the C shell or the D shell, which is conducive to the full metal design of the C shell and the D shell.

[0008] In one possible embodiment, the first metal shell includes: a C shell close to the display side and a D shell away from the display side, the connection between the D shell and the side of the first metal shell is an inclined surface, the non-metallic part is arranged on the inclined surface, and the second surface of the antenna bracket is arranged in a contour with the inclined surface.

[0009] This can facilitate the signal radiation of the excitation source and prevent the signal from being blocked by the desktop.

[0010] In a possible implementation, a second vent is provided on the non-metallic part, a third vent and a fourth vent are provided on the excitation source and the antenna bracket respectively, and at least part of the fourth vent and the third vent are connected to the ventilation channel.

[0011] On the one hand, the antenna assembly can assist the first vent in taking in or out air, and on the other hand, the appearance of the laptop computer can be improved.

[0012] In one possible embodiment, a grounding area is provided on the first surface of the antenna bracket, the grounding area on the first surface of the antenna bracket is connected to the grounding area on the second surface of the antenna bracket, and a flexible conductive part is provided on the grounding area on the first surface of the antenna bracket to connect to the first metal shell.

[0013] In this way, the ground area of ​​the antenna can be increased, thereby improving the overall performance of the antenna.

[0014] In a possible embodiment, electrical connection parts are provided on both end surfaces of the antenna bracket perpendicular to the ventilation channel and on the columns of each ventilation channel on the side away from the first vent, and the electrical connection parts connect the grounding area on the first surface of the antenna bracket and the grounding area on the second surface of the antenna bracket to form a resonant cavity antenna.

[0015] Compared to traditional antennas, the resonant cavity antenna does not require a complex feeding network, has a simple structure and is easy to produce and process, and is conducive to improving antenna directivity and sharpening beam width. It also helps to reduce the size of the radiation port opened on the first metal shell.

[0016] In a possible implementation, an excitation conductor is provided on a side wall of the ventilation channel, one end of the excitation conductor is connected to the excitation source, and the other end of the excitation conductor extends toward the first surface of the antenna support.

[0017] In this way, the metal coupling between the side wall of the C-shell and the keyboard side of the C-shell can be increased, which can effectively improve or compensate for the antenna efficiency and bandwidth.

[0018] In a possible implementation, there are at least two antenna assemblies, and the two antenna assemblies are disposed along two adjacent sides of the laptop computer.

[0019] In this way, the directivity of the antenna can be improved, and there can be certain improvements in comprehensive efficiency, directivity coefficient, isolation and OTA indicators compared with traditional antennas.

[0020] In a possible implementation manner, the antenna formed by the excitation source, the ground area, and the feeding point is an FPC antenna or an LDS antenna.

[0021] In a possible implementation, a gap is provided between the excitation source and the first metal shell, so as to increase the clearance area of ​​the antenna.

[0022] In a possible implementation, the first vent is provided on a side of the first metal housing hinged to the display and / or on a side of the first metal housing adjacent to the hinged side of the display, which is beneficial to improving user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0051] In the embodiments of the present application, the terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a" does not preclude the presence of additional identical elements in the process, method, article, or apparatus comprising the element.

[0052] Figure 1 is a structural schematic diagram of a laptop computer 100 provided in an embodiment of the present application, and Figure 2 is a structural schematic diagram of a laptop computer 100 provided in an embodiment of the present application. Referring to Figures 1 and 2, Figure 1 is a schematic diagram of the closed state of the laptop computer 100, and Figure 2 is a schematic diagram of the unfolded state of the laptop computer 100. The laptop computer 100 provided in an embodiment of the present application includes: a display 200 and a host 300.

[0053] Specifically, the display 200 may include a display screen 210 and a second metal housing 220. The display screen 210 is used to display images, videos, etc. The display screen 210 may be a flexible display screen or a rigid display screen. For example, the display screen 210 may be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode (OLED) display screen, a micro organic light-emitting diode (OLED) display screen, a micro organic light-emitting diode (OLED) display screen, a quantum dot light-emitting diode (QLED) display screen, or a liquid crystal display (LCD) display screen.

[0054] The second metal shell 220 is used to protect the display screen 210. The second metal shell 220 can cover the edge of the display screen 210 and the back of the display screen 210. In some embodiments of the present application, the second metal shell 220 can also be divided into an A shell and a B shell.

[0055] The host 300 may include: a host body 310, a keyboard 320 and a touchpad 330, wherein the keyboard 320 and the touchpad 330 are arranged on the host body 310. The keyboard 320 is used to input instructions or data. One working mode of the touchpad 330 is to act as a mouse, using the touch action of the user's finger (including sliding, clicking, etc.) to control the movement of the cursor on the display 200 to perform the mouse's "cursor navigation", "selection", "confirmation" and other operations. This working mode of the touchpad 330 is referred to as the mouse working mode in the embodiment of the present application. It should be noted that in the mouse working mode, the touchpad 330 can replace the mouse to control the laptop computer 100, or it can work in conjunction with the mouse to improve the portability of the laptop computer 100.

[0056] FIG3 is a schematic diagram of a partially disassembled structure of a laptop computer 100 according to an embodiment of the present application. Referring to FIG3 , a main body 310 may include a first metal housing 311 and electronic components housed within the first metal housing 311, including but not limited to a motherboard 313, a battery 312, a heat sink, a processor, and storage. The main body 310 is used to control the display 200 to display images and videos based on commands or data input from a keyboard 320, and to control cursor movement on the display 200 based on touch input from a touchpad 330.

[0057] In some embodiments of the present application, the first metal housing 311 may include a C housing 3111 and a D housing 3112 (as shown in FIG3 ). It should be noted that in the laptop computer 100, the housing is generally divided into an A housing, a B housing, a C housing 3111, and a D housing 3112. The A housing refers to the back cover of the display screen 210 (i.e., the topmost cover in FIG1 ), the B housing refers to the front bezel (i.e., the housing surrounding the edge of the display screen 210), the C housing 3111 refers to the top cover of the main unit 300 (i.e., the housing surrounding the edge of the keyboard 320 and touchpad 330), and the D housing 3112 refers to the bottom cover of the main unit 300 (i.e., the housing at the bottom of the laptop computer 100 when placed on a desktop). It is understood that the second metal housing 220 can be divided into an A housing and a B housing, or can be integrally formed. The same applies to the first metal housing 311. The first metal housing 311 can be divided into a C housing 3111 and a D housing 3112, or can be integrally formed. "Integrally formed" here means that the two components are formed into an inseparable whole through a process.

[0058] One side of the host body 310 is hinged to one side of the display 200. This application does not limit the form of the hinge connection between the host body 310 and the display 200. For example, as shown in Figures 2 and 3, the laptop computer 100 uses a vertical axis to hinge the C-shell 3111 to the second metal shell 220 of the display 200, allowing the laptop computer 100 to switch between an open state and a closed state. When the laptop computer 100 is in the open state, the display 200 and the host computer 300 form an angle greater than 0° and less than 180° (for example, as shown in Figure 2). When the laptop computer 100 is in the closed state, the display 200 covers the host computer 300, and the display surface of the display screen 210 faces the keyboard 320 of the host computer 300 (as shown in Figure 1).

[0059] Continuing with reference to Figure 3, in the laptop computer 100 provided in an embodiment of the present application, the electronic components within the host body 310 may include: a battery 312 and a motherboard 313. The battery 312 can provide power to the motherboard 313 and the display screen 210, and the motherboard 313 is connected to other electronic components and the display screen 210 to control the other electronic components and the display screen 210.

[0060] Generally, an antenna unit, such as a Wi-Fi antenna, is also required in the laptop computer 100. In the related art, for fully metal laptop computers 100, the antenna unit is typically designed within a plastic hinge cover at the hinge between the main body 310 and the display 200 to minimize the impact on the metal appearance of the second metal shell 220 of the display 200 and the first metal shell 311 of the main body 310. However, compared to a vertical hinge laptop computer 100, a solution with a plastic hinge cover leaves a plastic space below the display screen 210, preventing the laptop computer 100 from achieving a narrower bezel. Furthermore, the plastic hinge cover also affects the all-metal appearance of the laptop computer 100. When the antenna unit is designed within the second metal shell 220 of the display 200 or within the first metal shell 311 of the main body 310, windows need to be opened in the second metal shell 220 and the C-shell to allow the antenna unit to radiate. This approach compromises the metal integrity of the laptop computer 100 and affects the all-metal feel of the laptop computer 100.

[0061] In order to solve the above problems, an embodiment of the present application provides a laptop computer 100, in which the antenna assembly 400 is arranged at the ventilation port of the laptop computer 100, and utilizes the gaps in the partial shell surface of the D shell 3112 for radiation, greatly reducing the impact of the antenna on the metal shell, which is conducive to a narrow frame and full metal design.

[0062] The laptop computer 100 provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0063] 2 and 3 , the host body 310 further includes: a heat sink 314 and an antenna assembly 400 disposed in the first metal shell 311. The heat sink 314 is used to dissipate heat from the electronic components in the host body 310. Heat sink fins 3141 may also be provided at the air outlet of the heat sink 314 to improve the heat dissipation performance of the heat sink 314. The heat sink 314 may be a conventional fan or the like. This application does not limit the number and location of the heat sink 314 in the host body 310. For example, as shown in FIG3 , in some embodiments of the present application, a heat sink 314 is provided on each side of the mainboard 313 close to the hinged side of the display 200.

[0064] Figure 4 is a schematic structural diagram of an antenna assembly 400 according to one embodiment of the present application. Referring to Figure 4 and in conjunction with Figure 3 , antenna assembly 400 includes an antenna support 410, an excitation source 420, a grounding region 430, a feed point 440, and a flexible conductive member 450. Antenna support 410 can be a plastic support or a support formed by nanomolding (NMT). The antenna formed by excitation source 420 and feed point 440 can be a flexible printed circuit (FPC) antenna or a laser-direct-structuring (LDS) antenna.

[0065] Specifically, a first vent 315 is formed on the side wall of the first metal shell 311, which can be an air inlet or outlet for the laptop computer 100. The bracket antenna is formed with at least one ventilation channel 411. For example, the bracket antenna in FIG4 is formed with seven ventilation channels 411 arranged side by side, and the ventilation channels 411 are opposite and close to the first vent 315. Here, "the ventilation channels 411 are arranged close to the first vent 315" means that the ventilation channels 411 are arranged as close to the first vent 315 as possible, so that airflow entering from the outside through the first vent 315 can flow into the laptop computer 100 through the ventilation channels 411, or hot air blown out from the heat sink 314 can flow out of the first vent 315 through the ventilation channels 411.

[0066] In some embodiments of the present application, the first vent 315 can be arranged on a side where the first metal shell 311 is hinged to the display 200 and / or a side adjacent to the hinged side where the first metal shell 311 is hinged to the display 200. It can be understood that the first vent 315 is arranged away from the user operation side, which is conducive to improving the user experience.

[0067] The antenna bracket 410 has a first surface 412 facing the display 200 (i.e., the surface facing the laptop computer 100C housing 3111) and a second surface 413 facing away from the display 200 (i.e., the surface facing the laptop computer 100D housing 3112). Figure 5 shows a top view of a portion of the antenna assembly 400 according to one embodiment of the present application. The top view of the antenna assembly 400 in Figure 5 is taken from the perspective of the D housing 3112. Referring to Figure 5 and in conjunction with Figure 4, an excitation source 420 and a feed point 440 are disposed on the second surface 413 of the antenna bracket 410. The feed point 440 is connected to the excitation source 420. The feed point 440 is fed with a high-frequency signal by an antenna cable 340. The other end of the antenna cable 340 can be connected to the mainboard 313 of the laptop computer 100. The excitation source 420 can be spaced apart from the first metal housing 311 to increase the antenna's clearance area.

[0068] A grounding area 430 is provided on at least the second side 413 of the antenna bracket 410. The excitation source 420 is connected to the grounding area 430. A flexible conductive member 450 connects the grounding area 430 and the first metal shell 311. Exemplarily, the flexible conductive member 450 may be a conductive foam or the like. The flexible conductive member 450 connects the grounding area 430 on the second side 413 of the antenna bracket 410 and the D-shell 3112 of the laptop computer 100. Furthermore, the flexible conductive member 450 is located on a side of the excitation source 420 away from the first vent 315. This means that the flexible conductive member 450 is closer to the interior of the laptop computer than the excitation source 420.

[0069] Furthermore, as shown in FIG3 , a radiation port or non-metallic member 350 is provided in the area of ​​the first metal shell 311 facing the excitation source 420 to prevent interference with the excitation source 420 signal. For example, as shown in FIG3 , the non-metallic member 350 (e.g., a plastic member) is provided in the area of ​​the first metal shell 311 facing the excitation source 420. This prevents interference with the excitation source 420 signal and enhances the aesthetics of the laptop computer 100. Furthermore, the non-metallic member 350 can be painted the same or a similar color as the D-shell 3112, further enhancing the aesthetics of the laptop computer 100.

[0070] It is understood that the laptop computer 100 provided in the embodiment of the present application, by positioning the antenna assembly 400 at the first vent 315 of the main body 310, eliminates the need for the antenna assembly 400 to occupy space near the display 200, thereby achieving a narrow-border, full-screen, all-metal design near the display 200. It also eliminates the need for the antenna assembly 400 to occupy other internal space within the main body 310, thereby enhancing the aesthetics of the laptop computer 100. Furthermore, the excitation source 420 is located on the side of the antenna bracket 410 facing the D-shell 3112 (which can be understood as the side of the antenna bracket 410 facing the desktop when the laptop computer 100 is placed on a desktop). This facilitates the fully metalized design of the C-shell 3111 and enhances the aesthetics of the laptop computer 100. Furthermore, in actual use, the C-shell 3111 is typically a cover with a folded edge that is buckled onto the D-shell 3112. The fully metalized design of the C-shell 3111 enhances its overall strength. Furthermore, the flexible conductive member 450 is located on the side of the excitation source 420 away from the first vent 315. The flexible conductive member 450 can shield the excitation source 420 from signal interference from the interior of the laptop 100 and block electromagnetic noise. Compared to the method of arranging the excitation source 420 on the side of the antenna bracket 410 facing or away from the first vent 315, there is no need to set up a metal retaining wall to shield the excitation source 420 from signal interference, which is conducive to the lightweight and thinning of the laptop 100. At the same time, the radiation surface of the excitation source 420 faces the D shell 3112, and the area of ​​the D shell 3112 corresponding to the excitation source 420 is provided with a radiation port or a non-metallic member 350. This eliminates the need for a plastic outer frame as the exterior surface of the C shell 3111 or the D shell 3112, thereby facilitating the full metal design of the C shell 3111 and the D shell 3112.

[0071] It should be noted that the full metal design of the laptop computer 100 mentioned in this application does not mean that the shell of the laptop computer 100 is made entirely of metal, but rather means minimizing the use of materials other than metal. The most important thing is that the appearance of the A shell and the C shell are fully metal designed to meet the trend of full metal shell design.

[0072] Of course, the present application is not limited to this. FIG6 is a schematic cross-sectional view of a laptop computer 100 according to one embodiment of the present application. Referring to FIG6 , which can be viewed as a schematic diagram of the laptop computer 100 in an inverted position, in some embodiments of the present application, the first metal housing 311 may include a C-shell 3111 located on the side closest to the display 200 and a D-shell 3112 located on the side away from the display 200. The connection between the D-shell 3112 and the side of the first metal housing 311 is formed by an inclined surface 31121. The inclined surface 31121 may be an inclined plane or an inclined arc. FIG6 illustrates the inclined surface 31121 as an inclined plane. The second surface 413 of the antenna bracket 410 is configured to align with the inclined surface 31121. For example, when the inclined surface 31121 is an inclined plane, the second surface 413 of the antenna bracket 410 is configured to be an inclined plane. When the inclined surface 31121 is an inclined arc, the second surface 413 of the antenna bracket 410 is configured to be an inclined arc. This can facilitate the signal radiation of the excitation source 420 and prevent the signal from being blocked by the desktop.

[0073] FIG7 is a schematic structural diagram of the antenna assembly 400 of a laptop computer 100 according to an embodiment of the present application. Referring to FIG7 and in conjunction with FIG4 , in some embodiments of the present application, a second vent 351 may be provided on the non-metallic member 350, and a third vent 421 and a fourth vent 414 may be provided on the excitation source 420 and the antenna bracket 410, respectively. At least a portion of the fourth vent 414 and the third vent 421 are connected to the ventilation channel 411. This allows the antenna assembly 400 to assist the first vent 315 in air intake or exhaust, while also enhancing the aesthetics of the laptop computer 100 (see FIG8 for a rendering). Of course, if the antenna assembly 400 does not need to assist the first vent 315 in air intake or exhaust, the second vent 351, the third vent 421, and the fourth vent 414 are not required.

[0074] 4 , at least a portion of the fourth vent 414 is connected to the third vent 421. This means that the fourth vent 414 can also be provided on the second side 413 of the antenna support 410 where the excitation source 420 is not provided. Here, the fourth vent 414 is connected to the ventilation channel 411 but not to the third vent 421. The second side 413 of the antenna support 410 where the fourth vent 414 and the excitation source 420 are not required can be cut off, such as the cut-off portions 415 at both ends of the antenna support 410 that are recessed relative to the middle portion in FIG. 4 .

[0075] Among them, the number and shape of the first vent 315, the second vent 351, the third vent 421 and the fourth vent 414 are not limited in this application. For example, the first vent 315, the second vent 351, the third vent 421 and the fourth vent 414 can be one or more, and the shapes of the first vent 315, the second vent 351, the third vent 421 and the fourth vent 414 can be square holes, round holes or waist-shaped holes, etc.

[0076] Figure 9 is a bottom view of the antenna assembly 400 shown in Figure 5 , and Figure 10 is a rear view of the antenna assembly 400 shown in Figure 5 . Referring to Figures 9 and 10 in conjunction with Figure 5 , in some embodiments of the present application, a grounding area 430 may be provided on the first surface 412 of the antenna support 410 . The grounding area 430 on the first surface 412 of the antenna support 410 is connected to the grounding area 430 on the second surface 413 of the antenna support 410 . For example, as shown in Figure 10 , an electrical connector 460 may be provided on a surface of the antenna support 410 facing away from the first air outlet. The electrical connector 460 connects the grounding area 430 on the first surface 412 of the antenna support 410 with the grounding area 430 on the second surface 413 of the antenna support 410 . This increases the grounding area of ​​the antenna, thereby improving the overall performance of the antenna. Furthermore, a flexible conductive member 450 may be provided on the grounding area 430 on the first surface 412 of the antenna support 410 to connect to the first metal housing 311 (see Figure 7 ).

[0077] FIG11 is a side view of the antenna assembly 400 shown in FIG5 . Referring to FIG5 , FIG9 , FIG10 , and FIG11 , in some embodiments of the present application, electrical connectors 460 are provided on both end surfaces of the antenna perpendicular to the ventilation channel 411 and on the uprights of each ventilation channel 411 on the side away from the first vent 315. Electrical connectors 460 connect the grounding area 430 on the first side 412 of the antenna support 410 and the grounding area 430 on the second side 413 of the antenna support 410 to form a resonant cavity antenna. The excitation source 420, the grounding area 430, and the electrical connector 460 form an interconnected whole.

[0078] Compared with traditional antennas, the resonant cavity antenna does not require a complex feeding network, has a simple structure and is easy to produce and process, and is conducive to improving antenna directivity and sharpening beam width, and is conducive to reducing the size of the radiation port opened on the first metal shell 311.

[0079] Continuing with reference to FIG. 4 , in some embodiments of the present application, an excitation conductor 470 is provided on the side of the ventilation channel 411 . One end of the excitation conductor 470 is connected to the excitation source 420 , and the other end of the excitation conductor 470 extends toward the first surface 412 of the antenna bracket 410 . For example, as shown in FIG. 4 , the excitation conductor 470 can be formed on the sidewall of the ventilation channel 411 using an FPC or LDS, and the excitation conductor 470 is connected to the excitation source 420 using an electrical connection 460 . In this way, the amount of metal coupling between the sidewall of the C-shell 3111 and the side of the C-shell 3111 provided with the keyboard 320 can be increased, effectively improving or compensating for antenna efficiency and bandwidth. The present application does not limit the number of excitation conductors 470 , and can be one or more, with multiple excitation conductors 470 provided on the sidewall of each ventilation channel 411 .

[0080] Continuing to refer to FIG. 3 , in some embodiments of the present application, there are at least two antenna assemblies 400 , and the two antenna assemblies 400 are arranged along two adjacent sides of the laptop computer 100 , which can be understood as the two antenna assemblies 400 being arranged vertically.

[0081] FIG12 is a directional effect diagram of two antenna assemblies 400 provided in an embodiment of the present application in the 2.4G frequency band, and FIG13 is a directional effect diagram of two antenna assemblies 400 provided in an embodiment of the present application in the 5.5G frequency band. Referring to FIG12 and FIG13, when the two antenna assemblies 400 are arranged along the adjacent two sides of the laptop computer 100, the directivity of the antenna can be improved, and directional complementarity can be achieved at 2.4G / 5.5G. The antenna performance can be referred to Table 1 and Table 2. Table 1 shows the antenna efficiency and directivity coefficient, and Table 2 shows the OTA index. According to Tables 1 and 2, it can be seen that the two mutually perpendicular antennas have certain improvements in comprehensive efficiency, directivity coefficient, isolation and OTA index compared to traditional antennas.
