For example, the antenna device in a laptop is usually located at the laptop hinge, the non-metallic bezel below the screen, or a window / slit in the metal casing. This limited internal space layout restricts the radiation direction of the antenna device, making it difficult to achieve flexible directional control and spatial scanning, thus affecting the communication quality of the electronic device.

The antenna element layer includes a metasurface antenna array composed of a plurality of metasurface elements spaced apart and periodically arranged. The control layer includes a driving circuit signal-connected to the plurality of metasurface elements. The driving circuit is capable of controlling the operating parameters of at least a portion of the metasurface elements in the metasurface antenna array, and / or controlling the operating mode of the antenna device, in response to a target control signal from the control module.

[0006] On the other hand, embodiments of this application provide a control method for an electronic device, comprising: determining the operating mode of an antenna device of the electronic device, wherein the antenna device can perform different functional services under different operating modes; determining corresponding target signal data based on the operating mode, wherein the target signal data is used to generate a corresponding control signal; and controlling the operating parameters of the target metasurface unit in the metasurface antenna array of the antenna device based on the control signal corresponding to the target signal data.

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application are further described in detail below with reference to the accompanying drawings and embodiments. The described embodiments should not be regarded as limitations on this application. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] In the following description, references are made to “some embodiments,” which describe a subset of all possible embodiments. However, it is understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0020] It should be noted that the terms "first, second, and third" used in the embodiments of this application are merely to distinguish similar objects and do not represent a specific ordering of objects. It is understood that "first, second, and third" can be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein.

[0021] It will be understood by those skilled in the art that, unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which the embodiments of this application pertain. It should also be understood that terms such as those defined in general dictionaries should be understood to have a meaning consistent with their meaning in the context of the prior art, and should not be interpreted in an idealized or overly formal sense unless specifically defined as herein.

[0022] This application provides an electronic device, such as... Figure 1 As shown, the device includes a device body with a accommodating space and at least one control module 1 disposed in the accommodating space. The device body includes a first housing (not shown in the figure), and an antenna device 2 that is signal-connected to the at least one control module 1 is disposed in the first housing.

[0023] The antenna device 2 includes an antenna unit layer 22 and a control layer 21 stacked in the first housing along the thickness direction of the first housing;

[0024] The antenna element layer 22 includes a metasurface antenna array 221 composed of a plurality of metasurface elements spaced apart and arranged periodically.

[0025] The control layer 21 includes a drive circuit 211 that is signal-connected to the plurality of metasurface units. The drive circuit 211 is capable of controlling the operating parameters of at least some of the metasurface units in the metasurface antenna array 221 in response to a target control signal from the control module 1, and / or controlling the operating mode of the antenna device.

[0026] Here, "device body" can refer to the physical entity and core functional unit of an electronic device, but is not limited to external accessories connected to the device body, software or network connections built into the device body's memory or processor. For example, the device body can be the body of a mobile phone, a tablet computer, or a laptop computer. When the electronic device is of different types, the device body can be only the display portion, only the main unit, or both. For instance, the device body can be the main unit and display screen of a laptop computer, or the entirety of a mobile phone or tablet.

[0027] In some implementations, the control module can be implemented using a communication module and / or a control chip.

[0028] In one example, the control module can refer to a communication module, such as a wireless network (WiFi / WLAN) communication module, a wireless wide area network (WWAN) communication module, a Bluetooth communication module, an ultra-wideband (UWB) communication module, a satellite communication module, etc.

[0029] In one example, a control module can refer to an independent control chip, such as a Field-Programmable Gate Array (FPGA) chip, a Microcontroller Unit (MCU) chip, an Artificial Intelligence (AI) processor chip (such as an NPU), a Central Processing Unit (CPU), etc.

[0030] In some implementations, the control module can be a communication module plus a control chip, such as a WiFi communication module plus an FPGA chip. In this scenario, the control module works by sending the target control signal determined by the FPGA chip to the antenna device through the WiFi communication module.

[0031] The first housing refers to the housing in an electronic device that houses the antenna module. For example, in the case of a mobile phone, the first housing may refer to the back cover of the phone. If the mobile phone is a foldable phone, the first housing may also refer to the back cover of the foldable screen. In the case of a laptop computer, the first housing may refer to the back cover of the laptop's display screen. In the case of a tablet computer, the first housing may refer to the back cover of the tablet computer's back cover.

[0032] In some embodiments, the antenna element layer and control layer stacked in the thickness direction of the first housing may mean that the antenna element layer is disposed above the control layer in the thickness direction of the first housing.

[0033] In some embodiments, the antenna element layer may include a metasurface antenna array composed of several metasurface elements arranged at intervals and periodically. The metasurface element refers to a subwavelength structure formed by metal laser-etched on a flexible printed circuit (FPC). The subwavelength structure is the basic resonant unit for radiating and receiving electromagnetic waves. The subwavelength structure may refer to C-shaped, I-shaped, square open ring, or other structures.

[0034] In some implementations, a plurality of metasurface units may refer to at least two metasurface units, such as 20 metasurface units, 40 metasurface units, 6 metasurface units, 10 metasurface units, etc.

[0035] like Figure 2A and 2B As shown, the electronic device is a laptop computer, where the first shell refers to the A shell on the laptop computer. It can be seen that the A shell is provided with at least two metasurface units 2211.

[0036] In some implementations, the signal connection of several metasurface units to the driving circuit can mean that several metasurface units are electrically connected to the driving circuit, and / or that several metasurface units are coupled to the driving circuit.

[0037] In some implementations, miniaturized driving elements, such as digital-to-analog converters and operational amplifiers, are integrated on the driving circuit.

[0038] It should be noted that the row-column multiplexing technique enables the driving circuit to independently control each metasurface element in the metasurface antenna array. On one hand, the driving circuit can adjust the regulating elements in each metasurface element based on the acquired electrical signal of each metasurface element and the low-voltage DC signal source from the main board. On the other hand, the driving circuit can also determine which metasurface elements in the metasurface antenna array are in operation by controlling the state of the analog switches.

[0039] In some implementations, where the control module includes an FPGA chip, the target control signal can be determined by the FPGA chip and sent to the drive circuit.

[0040] In some implementations, where the control module includes a communication module, the target control signal may be determined by a processor on the system side of the electronic device and sent to the drive circuit via the communication module. Alternatively, the target control signal may be generated by a target application installed on the electronic device and sent to the drive circuit via the communication module. Alternatively, the target control signal may be configured by the user through the human-machine interface of the electronic device and sent to the drive circuit via the communication module.

[0041] In some embodiments, at least some metasurface elements may refer to metasurface elements in an operational state. It is understood that the number of metasurface elements in an operational state in this application may be less than or equal to the number of all metasurface elements in the metasurface antenna array. The metasurface elements in an operational state may be determined based on a target control signal, which may also be used to control the operating parameters of the metasurface elements in an operational state.

[0042] In some implementations, the operating parameters may include, but are not limited to, one or more of the following: enable state, phase, amplitude, resonant frequency, beam radiation direction, phase response, etc. The enable state is used to determine whether to activate the metasurface unit to enter the operating state.

[0043] In some implementations, the operating mode may refer to one of three modes: sensing mode, communication mode, and stealth mode. It is understood that the antenna device can perform different functional services in different operating modes. Specifically, in communication mode, the beam direction is adjusted by real-time monitoring of environmental signal strength and device attitude to establish an optimal communication link. In sensing mode, the device actively transmits detection signals and receives echoes, analyzing target motion characteristics through the Doppler effect to achieve target detection (through walls or without walls) and / or moving object detection. In stealth mode, destructive interference is used to suppress the propagation path of the device's own electromagnetic leakage signals, preventing attackers from intercepting signals transmitted by the electronic equipment.

[0044] In this embodiment, the traditional antenna device is moved out of the internal space of the electronic device and integrated into the first housing of the electronic device. On the one hand, this effectively utilizes the space resources of the device housing, reduces the size of the electronic device, and realizes the array arrangement of the antenna. On the other hand, by placing the antenna device on the first housing of the electronic device, the effective radiation aperture of the antenna device can be increased. This allows for precise control of the direction of the transmitted signal of the antenna device and significantly improves the signal transmission quality.

[0045] In some embodiments, the first housing further includes an outer layer disposed on a first side of the antenna unit layer opposite to the control layer, and a substrate layer disposed on a second side of the control layer opposite to the antenna unit layer. The substrate layer is used to provide mechanical support for the antenna device, and the outer layer can provide physical protection for the antenna device and / or allow electromagnetic waves of the target frequency band to pass through.

[0046] And / or,

[0047] Each of the metasurface units includes a subwavelength structure disposed on a first dielectric layer and an adjustment element disposed on the subwavelength structure. The adjustment element is capable of changing the impedance parameter of the subwavelength structure, thereby adjusting the resonance parameter of the metasurface unit.

[0048] Here, the outer layer is the surface layer located on the side of the antenna element layer facing away from the control layer. In other scenarios, the outer layer is also called a wave-transparent decorative protective layer. It's understandable that, on the one hand, the outer layer provides physical protection for the antenna device; therefore, when selecting materials for the outer layer, the chosen materials should have sufficient structural strength to ensure wear resistance, scratch resistance, and impact resistance. On the other hand, the outer layer also allows electromagnetic waves of the target frequency band to pass through. Therefore, to minimize electromagnetic loss when electromagnetic waves of the target frequency band pass through the outer layer, the design of the outer layer should comprehensively consider both material selection and thickness. Furthermore, the outer layer can be decorated; for example, by spraying color onto the outer layer, applying a personalized coating, or integrating brand logos. This allows the antenna device to appear "invisible," without affecting the overall appearance design of the electronic device. Additionally, when determining the outer layer, it should be ensured that its wave transmittance is greater than 90%.

[0049] like Figure 3 As shown, the outer layer 24 is located above the antenna element layer 22. The outer layer 24 can be made of composite materials such as engineering plastics, thin glass, and ceramics.

[0050] In some implementations, the target frequency band is related to the network environment supported by the electronic device. For example, when the network environment is WiFi, the target frequency band may refer to 2.4GHz / 5GHz / 6GHz / 7GHz. When the network environment is Bluetooth, the target frequency band may refer to 2.4GHz. When the network environment is mobile communication, the target frequency band may refer to 2.6GHz / 3.5GHz / 28GHz / 39GHz or 422MHz.

[0051] The substrate layer is a structural material located below the control layer. Its main function is to provide stable mechanical support for the entire antenna device. In some embodiments, the substrate layer can be made of a carbon fiber-aramid blend material, which has high strength, lightweight, and good thermal stability. Therefore, it can effectively prevent external stress from causing deformation or damage to the internal structure of the antenna, thereby ensuring the stability and reliability of the antenna device.

[0052] like Figure 3 As shown, the substrate layer 23 is located below the control layer 21, and the substrate layer 23 can be made of a carbon fiber-aramid blend material.

[0053] In some embodiments, the first dielectric layer may refer to an FPC, wherein the FPC is a circuit board with conductive lines formed by etching process on a polyimide (PI) or polyester film (PET) substrate.

[0054] Subwavelength structures are periodic or quasi-periodic structures with dimensions smaller than the operating wavelength, used to control the electromagnetic waves emitted by metasurface units, thereby enabling metasurface antennas to achieve dynamic beam scanning and shaping functions. Subwavelength structures can take various forms, such as C-shapes, I-shapes, and square open rings, which can be flexibly configured according to design requirements to meet the electromagnetic wave control requirements of different application scenarios.

[0055] Adjustable elements are tunable components integrated into each metasurface unit, used to adjust the impedance parameters of the subwavelength structure in real time. These adjustable elements can be varactor diodes, PIN diodes, liquid crystals, graphene, etc. Figure 2B As shown, each metasurface unit 2211 includes a subwavelength structure 31 and an adjustment element 311 disposed on the subwavelength structure.

[0056] In some implementations, the impedance parameters of the subwavelength structure can be adjusted by controlling the capacitance and / or inductance of the regulating element.

[0057] It should be noted that the metasurface unit includes a subwavelength structure and a tuning element. This configuration enables the metasurface unit provided in this application to not only achieve the ability to control electromagnetic waves, but also to have high flexibility and adaptability, making it suitable for task requirements in various scenarios.

[0058] In some implementations, the overall impedance value of the metasurface unit can be adjusted by changing the impedance parameters of the subwavelength structure, thereby achieving the adjustment of the resonant parameters of the metasurface unit.

[0059] In some implementations, the polarization, phase, amplitude, and other characteristics of electromagnetic waves emitted by the metasurface unit can be flexibly controlled by adjusting the resonance parameters of the metasurface unit.

[0060] In this embodiment, by providing a substrate layer and an outer layer in the first housing, the antenna module not only achieves structural stability and aesthetics but also ensures efficient transmission of electromagnetic waves. Furthermore, by introducing tunable adjustment elements into each metasurface unit, the resonant parameters become dynamically controllable, thereby enabling dynamic beamforming of the antenna device and the control of various operating modes.

[0061] In some embodiments, the outer layer is made of a transparent material and the transmittance of the outer layer is greater than 90%, or the surface of the outer layer facing away from the antenna device is provided with a first coating and / or a preset mark, the first coating being capable of presenting a preset pattern and / or color;

[0062] And / or,

[0063] The antenna unit layer also includes a control line grid connected to the adjustment element of each metasurface unit. The control line grid is electrically connected to a first driving circuit within the control layer. The control line grid is used to control the target adjustment element to provide target capacitance and / or target inductance to change the resonant parameters of the metasurface unit.

[0064] And / or,

[0065] The control layer also includes a second driving circuit, which is electrically connected to the subwavelength structure of the plurality of metasurface units via a plurality of pins, or the second driving circuit is coupled to the subwavelength structure of the plurality of metasurface units via a coupling power supply to transmit a power supply signal to the subwavelength structure.

[0066] Here, transparent material refers to material that allows both visible light and electromagnetic waves to pass through simultaneously, such as composite materials like polycarbonate (PC) and polymethyl methacrylate (PMMA). Transmittance refers to the ability of a transparent material to transmit electromagnetic waves of a target frequency band; higher transmittance indicates less attenuation of electromagnetic waves within the transparent material. In this application, by ensuring the transmittance of the outer layer is greater than 90%, electromagnetic waves can be efficiently transmitted through the outer layer without affecting the communication and sensing functions of the electronic device. Furthermore, transparent materials preserve the overall aesthetics of the device and allow users to observe the presence of the metasurface antenna array, thereby enhancing the product's technological appeal.

[0067] The first coating is a customizable decorative layer that can be applied to the surface layer through methods such as spraying, printing, or laser engraving. The first coating is not only used to decorate electronic devices but can also provide certain functionalities, such as fingerprint resistance, scratch resistance, or enhanced adhesion. Pre-designed markings refer to pre-designed graphics, custom patterns, or text marks used to distinguish product models, serial numbers, or other information; for example, a pre-designed marking could be a brand logo.

[0068] It should be noted that placing the first coating and / or pre-defined markings on the visible surface of the appearance layer not only enhances the visual appeal of electronic devices but also meets the needs of industrial design and brand promotion.

[0069] Preset patterns refer to graphic styles that are predetermined during the manufacturing process, such as geometric shapes, corporate logos, and gradient color blocks. For example, a preset pattern could be a co-branded pattern. Color refers to the selection and combination of colors, which can be achieved through pigment mixing, electronic ink, or luminescent materials.

[0070] Understandably, the first coating enables electronic devices to exhibit rich visual effects, allowing for product personalization and the conveying of specific information. For example, in business settings, simple monochrome logos can be used, while in consumer electronics, dynamic color changes or holographic effects can be employed to attract younger users.

[0071] In some implementations, the first coating may be a coating with a specific color, and the preset pattern may be a brand co-branded pattern.

[0072] The control line grid is an active matrix grid composed of metal wires. In this application, the control line grid covers the entire antenna element layer and is connected to the driving circuit of the control layer through connecting lines. The driving circuit may include a first driving circuit and a second driving circuit. The first driving circuit is used to control the adjustment element through DC power, and the second driving circuit is used to feed the feed current to the subwavelength structure through AC power.

[0073] In some embodiments, the control line grid is also connected to the adjustment element of each metasurface unit. This allows the drive voltage or drive current generated by the first drive circuit to be sent to the target adjustment element to control it to have a target capacitance and / or target inductance. The target capacitance and / or target inductance are related to the resonant frequency and phase response of the metasurface unit. By adjusting the target capacitance and / or target inductance, dynamic control of electromagnetic waves can be achieved. For example, when the adjustment element is a diode, each row and column of control lines in the control line grid is used to address and provide a bias voltage to the diode of each metasurface unit, changing the junction capacitance of the diode and thus controlling it. This allows for continuous, analog alteration of the resonant frequency and phase response of the entire metasurface unit.

[0074] In some implementations, the target capacitance and / or target inductance are determined based on the operating mode and / or usage scenario of the antenna device.

[0075] In some implementations, PIN pins are provided on the back of the subwavelength structure to directly connect to the second driving circuit of the control layer. A PIN pin is a physical connector composed of metal pins, commonly used in high-precision, low-impedance electrical connection applications. Using PIN pins as a connection means, the feed signal can be directly introduced into the subwavelength structure of the metasurface unit through the second driving circuit, achieving efficient signal transmission.

[0076] In some implementations, the subwavelength structure is coupled to the second driving circuit via a coupling connection. This coupling feeding method is a non-contact connection that utilizes electromagnetic induction to transmit the feeding signal from the second driving circuit to the subwavelength structure via electromagnetic waves. The advantage of coupling feeding is that it eliminates the need for physical contact, reducing the risk of mechanical wear and signal interference.

[0077] In practical implementation, the dynamic control and stable power supply of the metasurface antenna system are achieved through the cooperation of the outer layer, control line grid, first driving circuit, and second driving circuit. Among them, the outer layer, as the external encapsulation structure, not only has good wave transmission performance but also can carry decorative and identification information; the control line grid and driving circuit together constitute the control system, which is used to achieve precise adjustment of the operating parameters of the metasurface unit.

[0078] In this embodiment, on the one hand, the outer layer is used as an external encapsulation structure, which not only provides good physical protection for the antenna device, but also ensures that the outer layer does not affect the antenna's performance and can also serve as a decorative and branding display function, improving the usability of the electronic device. On the other hand, the use of the control line grid in conjunction with the adjustment elements enables precise control of the capacitance or inductance of each adjustment element, thereby achieving control of the electromagnetic waves emitted by the metasurface unit. Furthermore, the second driving circuit is connected to the subwavelength structure through various methods such as pins or coupled feeding, which enhances the compatibility and flexibility between the driving circuit and the antenna.

[0079] In some embodiments, the subwavelength structure includes a first annular branch and a second annular branch sleeved on the first annular branch. The first annular branch and the second annular branch are connected by two symmetrically arranged first branches, and the second annular branch is provided with two first gaps near the position connecting the two first branches. The two first gaps divide the second annular branch into two spaced second branches, and the adjustment element is disposed in the first gap.

[0080] And / or,

[0081] The subwavelength structure is a centrally symmetrical graphic structure formed by bending at least one branch.

[0082] Here, the first annular stub refers to the stubs distributed in a ring around the center point, and their function is to form the basic electromagnetic resonance path. The second annular stub refers to another layer of annular stubs located outside the first annular stub and concentric with it, used to further extend the electromagnetic response range and enhance the control over electromagnetic waves.

[0083] The first branch refers to the branch connecting the first annular branch and the second annular branch. The function of the first branch is to establish an electrical connection between the first annular branch and the second annular branch. In this application, by symmetrically arranging the two first branches, the uniformity and symmetry of the electromagnetic response in the horizontal direction of the structure formed by the first branches can be ensured.

[0084] In some implementations, the first and second annular branches can be rectangular branches.

[0085] In some embodiments, the connection point between the two first branches and the first annular branch is the long side of the rectangular branch corresponding to the first annular branch. The two first branches can be positioned at any location along the long side and are symmetrically distributed. This arbitrary location can be the center of the long side, two-thirds of the long side, or four-thirds of the long side.

[0086] The first slit refers to the narrow opening carved into the second annular branch. The first slit is used to introduce adjustment elements to achieve dynamic electromagnetic response.

[0087] Branch bending refers to bending branches that originally extend vertically at a certain angle to form a specific geometric shape. In this application, the pattern formed by bending at least one branch is centrally symmetrical, which can reduce asymmetric interference of electromagnetic waves, thereby improving signal consistency and stability.

[0088] like Figure 4 As shown, the subwavelength structure includes a first annular stub 312 and a second annular stub 313 sleeved on the first annular stub. The first annular stub 312 and the second annular stub 313 are connected by two symmetrically arranged first stubs 314. The second annular stub has two first gaps near the position connecting the two first stubs. The two first gaps divide the second annular stub into two spaced-apart second stubs. The adjustment element 311 is disposed within the first gap.

[0089] In this embodiment, by introducing multiple layers of annular stubs, symmetrically connected stubs, and embedded adjustment elements into the subwavelength structure, efficient control and dynamic regulation of electromagnetic waves can be achieved. Alternatively, by employing a centrally symmetrical graphic structure formed by bending at least one stub, symmetrical regulation and uniform distribution of electromagnetic waves can be achieved, thereby enabling efficient control and dynamic regulation of electromagnetic waves.

[0090] In some embodiments, the device body includes a display portion consisting of at least a first housing and a display screen, or the device body includes a host portion consisting of at least a first housing and an input device;

[0091] And / or,

[0092] The control module includes at least one of the following: a communication module for implementing target communication functions, a processor chip for controlling the operating mode of the antenna device, and a processor of an electronic device.

The target reference data includes at least one of the following: environmental perception data of the space environment in which the electronic device is located, operating data of the electronic device, and user configuration data.

[0093] In some implementations, when the electronic device includes a display screen, the first housing may refer to the housing corresponding to the display screen of the electronic device. In one example, when the electronic device is a mobile phone or a tablet, and the mobile phone or tablet is full-screen, the display portion may refer to the mobile phone or tablet; when the electronic device is a mobile phone or a tablet, and the mobile phone or tablet is not full-screen, the display portion may refer to the display screen of the mobile phone or tablet and the housing on the side of the display screen; when the electronic device is a monitor, the display portion may refer to the monitor.

[0094] In some embodiments, when the electronic device includes an input device, the first housing may refer to the housing corresponding to the input device of the electronic device. The input device may refer to a component through which the user interacts with the electronic device, such as a keyboard, a touchscreen, or a combination of a keyboard and a touchscreen. In one example, when the electronic device is a mobile phone or a tablet, and the mobile phone or tablet is full-screen, the host portion may refer to the mobile phone or tablet; when the electronic device is a mobile phone or a tablet, and the mobile phone or tablet is not full-screen, the host portion may refer to the touchscreen of the mobile phone or tablet and the housing on the touchscreen side, or the host portion may refer to the keyboard of the mobile phone or tablet and the housing on the keyboard side, or the host portion may refer to the keyboard of the mobile phone or tablet, the housing on the keyboard side, the touchscreen, and the housing on the touchscreen side. When the electronic device is a laptop computer, the display portion may refer to the keyboard and the housing on the keyboard side, or the host portion may refer to the keyboard of the laptop computer, the housing on the keyboard side, the touchscreen, and the housing on the touchscreen side.

[0098] Target reference data is a crucial basis for the control module to control the antenna device's operating mode, primarily including at least one of the following: environmental perception data, electronic device operating data, and user configuration data. Environmental perception data can refer to network signal data, such as signal quality, signal strength, beam direction, and interference signals; it can also be obstacle data, human or other object proximity data, detected by proximity sensors, optical sensors, infrared sensors, or antenna broadcast signals. Environmental perception data can also include obstruction parameters such as the presence of approaching humans or external objects, obstruction area, environmental interference signals (interference frequency bands), and spatial dimensions and material data. Electronic device operating data can refer to currently running applications, system load, and battery level. User configuration data refers to data configured by the user through the human-machine interface to determine the antenna's operating mode.

[0099] In this embodiment, on the one hand, the device body adopts a modular design, which facilitates flexible configuration of the first housing according to different device bodies. On the other hand, by configuring the control module as at least one of a communication module, a processor chip, and a processor, the control module can determine the operating mode of the antenna device based on the target reference data, thereby enabling the antenna device to meet the communication needs of different scenarios corresponding to the target parameter data.

[0100] In some embodiments, the device body includes a first body and a second body rotatably connected, the first body including a display portion consisting of at least a first housing and a display screen, the second body including a host portion consisting of at least a second housing and an input device, and the control module being disposed within the accommodating space formed by the host portion;

[0101] The electronic device also includes a detection circuit that is signal-connected to the control module. The detection circuit is used to detect the device shape of the electronic device and / or to acquire environmental perception data of the spatial environment in which the electronic device is located. The control module can adjust the operating parameters of the target metasurface unit in the metasurface antenna array based on the device shape and / or the environmental perception data.

[0102] In some embodiments, the first body and the second body are connected by a pivot, for example, as shown in the figure. Figure 2AAs shown in 2B, when the electronic device is a laptop computer, the first body can refer to the display screen side of the laptop computer, and the second body can refer to the keyboard side of the laptop computer. In this case, the first shell can refer to the A shell of the laptop computer, and the second shell can refer to the D shell of the laptop computer.

[0103] A detection circuit is an electronic module used to detect the form and / or external environment information of an electronic device, and sends the detected data to a control module, thereby enabling the control module to regulate the operating mode of the electronic device. The detection circuit establishes a data transmission channel with the control module through a communication interface. The introduction of the detection circuit allows the electronic device to perceive changes in its own form and changes in its surrounding environment, thus enabling the electronic device to achieve more intelligent functional responses.

[0104] In some implementations, the detection circuit may include sensors for detecting the shape of the electronic device, such as angle sensors, proximity sensors, optical sensors / infrared sensors disposed between the A-shell and D-shell of the electronic device, and sensors such as inertial measurement units (IMUs) disposed in the main unit; or other types of detection devices.

[0105] In some implementations, the detection circuit may further include sensors for acquiring environmental perception data, such as optical sensors, millimeter-wave radar, and infrared sensors. An optical sensor is a device that converts light signals (such as intensity, wavelength, phase, polarization, etc.) into electrical signals. Its core function is to sense the physical and chemical properties of the environment or target objects in a non-contact manner, and to achieve high-precision, high-reliability data acquisition and transmission.

[0106] Device form refers to the current physical state of an electronic device, such as the opening angle of the screen, the relative positional relationship between side A and side D, the folding form of the electronic device, and the horizontal or vertical screen form of the electronic device.

[0107] In some implementations, the control module determines the operating mode of the antenna device based on device configuration and / or environmental perception data. If the operating mode of the antenna device differs from the current operating mode, the module adjusts the operating parameters of the target metasurface unit to ensure the antenna device operates in the correct mode. These operating parameters can refer to the beam radiation direction, phase response, or resonant frequency.

[0108] In some implementations, the control module determines the operating mode of the antenna device based on device configuration and / or environmental perception data; when the operating mode of the antenna device is consistent with the current operating mode, the control module adjusts the operating parameters of the target metasurface unit to enable the antenna device to have better signal transmission and reception quality, improve the communication performance of electronic devices, and enhance communication security.

[0109] In this embodiment, by integrating a detection circuit into the electronic device, real-time data on device shape and environmental perception is acquired, and the operating parameters of the target metasurface unit in the metasurface antenna array are dynamically adjusted based on this data. This method enables adaptive optimization of antenna performance, thereby improving the communication efficiency of the electronic device and enhancing its security and user experience.

[0110] This application provides a control method for an electronic device, such as... Figure 5 As shown, steps S500 to S520 are included:

[0111] Step S500: Determine the operating mode of the antenna device of the electronic device, wherein the antenna device can perform different functional services under different operating modes;

[0112] In some implementations, the operating mode of the antenna device can be determined based on at least one of the following: application operation information of the electronic device, user configuration operation data, current environmental data, and user data of the electronic device. For example, if the user configuration operation data includes the operating mode selected by the user through the interactive interface of the electronic device, the user-selected operating mode is determined as the operating mode of the antenna device. Alternatively, user profile information of the user is determined based on the user data of the electronic device; the operating mode of the antenna device is determined based on this user profile information. Or, if the application operation information of the electronic device includes conferencing applications, the operating mode of the antenna device is determined to be a communication mode.

[0113] In some embodiments, the operating mode of the antenna device can be one of a communication mode, a sensing mode, or a stealth mode. The communication mode is used to optimize the communication quality of the electronic device; the sensing mode is used to detect targets and / or moving objects, whether behind walls or not, in the spatial environment where the electronic device is located; and the stealth mode is used to interfere with attackers' acquisition of signals transmitted by the electronic device. In this application, the communication mode, sensing mode, and stealth mode can be dynamically switched, or multiple modes can be run simultaneously to meet the task requirements in complex scenarios.

[0114] Understandably, the antenna device can provide different functional services in different operating modes. In communication mode, the antenna device optimizes the data transmission path and improves the signal transmission rate. In sensing mode, the antenna device detects target objects and / or moving objects that are behind or outside walls. In stealth mode, the antenna device achieves "electromagnetic stealth" of the terminal device, making the signals sent by the electronic device unable to be effectively received and decoded by attackers.

[0115] Step S510: Determine the corresponding target signal data based on the working mode, and the target signal data is used to generate the corresponding control signal;

[0116] In some implementations, the target signal data differs depending on the operating mode. Specifically, in communication mode, the target signal data can be the signal strength, frequency band, and signal pattern of network service devices such as WiFi or base stations within the environment where the electronic device is located; in sensing mode, the target signal data can refer to Frequency Modulated Continuous Wave (FMCW) scanning beam information and / or echo information; and in stealth mode, the target signal data can refer to the frequency band, direction, and phase of electromagnetic leakage radiation.

[0117] Step S520: Control the operating parameters of the target metasurface unit in the metasurface antenna array of the antenna device based on the control signal corresponding to the target signal data.

[0118] In some implementations, the control signal may include a power supply signal, a voltage or current signal for adjusting the element, a switch control signal for enabling the target metasurface element, and a switch control signal for disabling the metasurface elements outside the target metasurface element in the metasurface antenna array.

[0119] In some implementations, the target metasurface element can be a metasurface element used to put the antenna device into an operating mode. The target metasurface element can be all or part of the metasurface elements in the metasurface array, wherein the number and / or positional distribution information of the target metasurface element is different in different operating modes.

[0120] In some implementations, the target metasurface unit can be determined based on the switch control signal in the control signal.

[0121] In some implementations, the operating parameters may include, but are not limited to, one or more of the following: enable state, phase, amplitude, resonant frequency, beam radiation direction, phase response, etc.

[0122] In this embodiment, after determining the working mode of the antenna device, the target signal data is determined based on the working mode, thereby generating a control signal to control the working parameters of the target metasurface unit in the metasurface antenna array of the antenna device. This enables the antenna device to provide the functional services corresponding to the working mode. Through this method, the corresponding working mode can be adapted to different scenarios, thereby enabling the antenna device to provide the functional services corresponding to the scenario and further enhancing the user experience.

[0123] In some embodiments, step S510 above includes at least one of steps S511 to S513:

[0124] Step S511: When the antenna device is in the first working mode, monitor the network signal data provided by the target network device in the spatial environment where the electronic device is located, and use the network signal data as the target signal data corresponding to the first working mode. The target network device is a device that can provide network services.

[0125] Here, the first operating mode can refer to the communication mode. The target network device refers to a device capable of providing wireless network access or communication services, such as a router, Bluetooth gateway, cellular base station, access point (AP) device, hotspot device, etc. Target network devices typically have the ability to transmit and receive electromagnetic waves and can provide a stable network connection for terminal devices (such as laptops).

[0126] In this application, there is a logical relationship between the target network device and the antenna device. That is, the antenna device optimizes the data transmission path of the electronic device by monitoring the network signal data emitted by the target network device in real time, thereby improving the communication quality of the electronic device.

[0127] For example, when a user uses a laptop, the antenna within the laptop continuously scans the surrounding environment, identifying and locking onto multiple target network devices, such as home Wi-Fi routers or base stations within a company. By using network signal data provided by the target network devices, such as signal strength, channel state information (CSI), and transmission delay, the system determines the optimal data transmission path for the current communication quality. This allows for adjustments to the metasurface array's beam direction, phase response, resonant frequency, and other parameters to match the optimal data transmission path, thereby improving signal transmission efficiency.

[0128] In this embodiment of the application, by monitoring the network signal data provided by the target network device, the operating parameters of the target metasurface array can be dynamically adjusted, the data transmission path of the electronic device can be optimized, thereby improving the communication quality of the electronic device, enhancing the user experience, and increasing the adaptability of the electronic device in the network environment.

[0129] Step S512: When the antenna device is in the second working mode, the frequency modulation signal required to perform frequency modulation continuous wave scanning is used as the target signal data corresponding to the second working mode;

[0130] Here, the second operating mode can refer to the sensing mode. Frequency-modulated continuous wave (FM-CW) is a method of measuring target distance and velocity by transmitting a continuous wave signal whose frequency varies over time and utilizing the frequency difference between the transmitted and echo signals.

[0131] Understandably, to achieve the sensing mode, the beam direction and resonant frequency of the metasurface antenna array need to be adjusted to the frequency-modulated (FM) signal required for FM continuous wave scanning to detect moving objects or targets. This sensing mode primarily involves two detection scenarios: detection of moving objects or targets behind obstacles, and detection of moving objects or targets without obstacles. When the sensing mode is activated, the control antenna device transmits a preset FM continuous wave with preset operating parameters. The preset FM continuous wave is updated using the first echo information to obtain an FM continuous wave matching the detection scenario. For example, for detecting moving objects or targets behind obstacles, if the obstacle is a wall, appropriate operating parameters need to be selected based on the wall type to adjust the preset FM continuous wave, ensuring that the adjusted FM continuous wave can detect moving objects or targets behind obstacles. Alternatively, for detecting moving objects or targets without obstacles, appropriate operating parameters also need to be selected based on the type of moving object or target to adjust the preset FM continuous wave, ensuring that the adjusted FM continuous wave improves the detection accuracy of moving objects or targets.

[0132] In this application, the frequency-modulated (FM) signal required for FM continuous wave scanning is a signal adjusted from a preset FM continuous wave. When the trigger antenna device emits the FM signal required for FM continuous wave scanning, Doppler analysis is performed on the echo signal reflected by the moving object or target object to obtain its characteristic information. For example, if the target object is a person or animal, this characteristic information may be its movement speed and / or heart rate. In some embodiments, the obtained characteristic information can also be displayed on the screen of a mobile device.

[0133] In this embodiment of the application, by using a frequency modulation signal, a high-precision object perception function can be achieved in the second working mode, enabling the electronic device to detect moving objects or moving objects behind obstacles in the current environment, thereby supporting advanced application scenarios such as wall target detection and respiratory rate monitoring, and thus expanding the functional boundaries of the electronic device.

[0134] Step S513: When the antenna device is in the third working mode, the electromagnetic wave signal generated by the target component of the electronic device is used as the target signal data corresponding to the third working mode.

[0135] Here, the third working mode can refer to stealth mode. The target component refers to the component that allows the user to interact with the electronic device, such as a keyboard, touchpad, or touchscreen.

[0136] It should be noted that the target component generates electromagnetic wave signals during operation, which may carry sensitive information, such as user input or data being processed. Therefore, using electromagnetic wave signals as target signal data allows for the assessment of electromagnetic leakage in electronic devices and the implementation of corresponding protective measures. For example, the system can dynamically adjust the metasurface antenna array based on the target signal data. This allows the array to emit a reverse wave with a 90-degree phase difference and the same amplitude as the electromagnetic wave generated by the target component, creating destructive interference. This prevents the emitted electromagnetic wave from being received by devices in a specific direction, achieving stealth protection and reducing or eliminating the risk of privacy leaks. For instance, the direction of the electromagnetic wave signal can be used to identify an attacker in that direction, and based on the attacker's direction, the direction of the signal emitted by the metasurface antenna array can be determined.

[0137] In this embodiment of the application, by monitoring the electromagnetic wave signals generated by the target component, attackers can be prevented from obtaining sensitive user information in the electronic device through electromagnetic side-channel attacks, thereby ensuring the security of the electronic device and enhancing users' trust in and sense of security in using the smart terminal.

[0138] It should be noted that in the first and third operating modes, the type of signal transmitted by the control antenna device is the same, while the type of signal transmitted by the antenna device in the second operating mode is different from that in the first and third operating modes. For example, in the first and third operating modes, the control antenna device transmits electromagnetic wave signals, while in the second operating mode, the control antenna device transmits frequency-modulated continuous wave signals.

[0139] In this embodiment of the application, by selecting the corresponding target signal data in different working modes, the antenna device can be flexibly switched between communication mode, sensing mode and stealth mode, which can meet the user's needs for electronic devices in various complex environments, thereby improving the intelligence level of electronic devices.

[0140] In some embodiments, step S520 above includes one of the following steps S521 to S523:

[0141] Step S521: Control the operating parameters of the target metasurface unit in the metasurface antenna array of the antenna device based on the preset control signal corresponding to the operating mode;

[0142] Here, the pre-configured control signals are determined directly based on the mapping table between the operating modes and control signals stored in the electronic device, which is the pre-configured operating parameters of the antenna array required in different operating modes.

[0143] It is understandable that there is a close relationship between the operating mode and the preset control signal. The operating mode determines which type of preset control signal the system should use, and the preset control signal is the key foundation for achieving the electromagnetic control required in a specific operating mode. Therefore, after the system enters a certain operating mode, the system first loads the corresponding preset control signal.

[0144] The target metasurface unit can refer to all or part of the metasurface units in the metasurface array. The number and / or location distribution information of the target metasurface units are different under different operating modes.

[0145] In some implementations, the operating parameters may include, but are not limited to, one or more of the following: enable state, phase, amplitude, resonant frequency, beam radiation direction, phase response, etc.

[0146] Step S522: Obtain device form data of electronic device, optimize the control signal based on the device form data, and use the optimized control signal to control the operating parameters of the target metasurface unit in the metasurface antenna array. The target metasurface unit is at least a portion of a plurality of metasurface units in the metasurface antenna array.

[0147] In some implementations, device configuration data is input to a beam deflection compensation module, which determines the operating parameters of the target metasurface unit. The operating parameters of the target metasurface unit are then input to a phase codebook generation module, which determines the operating parameters as well.

[0148] It should be noted that optimizing control signals based on device shape data means that the system can automatically adjust the operating parameters of the target metasurface unit according to the current device shape of the electronic device to adapt to changing electromagnetic propagation paths. For example, when a user tilts a laptop, the voltage configuration of the target metasurface unit can be adjusted using the device shape data to maintain optimal directivity of the radiation beam and prevent signal attenuation caused by changes in device shape.

[0149] Step S523: Obtain environmental perception data of the space environment in which the electronic device is located, optimize the control signal based on the environmental perception data, and use the optimized control signal to control the operating parameters of the target metasurface unit in the metasurface antenna array. The target metasurface unit is at least a portion of a plurality of metasurface units in the metasurface antenna array.

[0150] In some implementations, environmental perception data is input to a beam deflection compensation module, which determines the operating parameters of the target metasurface unit. These operating parameters are then input to a phase codebook generation module, which determines the control signal.

[0151] It should be noted that optimizing control signals based on environmental perception data means that the system can automatically adjust the operating parameters of the target metasurface unit according to the environmental perception data to adapt to changing electromagnetic propagation paths. For example, when the environment in which the laptop is located changes, the voltage configuration of the target metasurface unit can be adjusted based on the environmental perception data of the electronic device's environment, thereby maintaining the optimal directivity of the radiation beam (e.g., the direction of the optimal transmission path in communication mode, or the direction of destructive interference in stealth mode), preventing signal attenuation caused by changes in the environment in which the electronic device is located.

[0152] In some implementations, environmental perception data of the spatial environment in which the electronic device is located and device form data of the electronic device are obtained. Based on the environmental perception data and device form data, the control signal is optimized and processed. The optimized control signal is used to control the operating parameters of the target metasurface unit in the metasurface antenna array. The target metasurface unit is at least a portion of a plurality of metasurface units in the metasurface antenna array.

[0153] In one example, when the environmental sensing data includes network signal data, the first beam radiation direction of the metasurface antenna array is calculated based on the network signal data and device form data using a beam deflection compensation module. This first beam radiation direction is then input to a phase codebook generation module, which outputs the operating parameters of the target metasurface unit. The specific implementation process is described below, and may include steps S1 to S4:

[0154] Step S1: Obtain network signal data and device status data.

[0155] In some implementations, after receiving first electromagnetic wave signals emitted by target network devices in the environment where the electronic device is located, signal strength analysis is performed on the multiple first electromagnetic wave signals to determine the network signal data corresponding to the multiple first electromagnetic wave signals; based on the multiple network signal data, first direction information is determined; the first direction information may be the direction corresponding to the electromagnetic wave signal with the strongest signal strength in the target environment, that is, the direction of the target network device corresponding to the electromagnetic wave signal.

[0156] In some implementations, device form data may include first angle information of the first housing relative to a horizontal plane, and second angle information describing the first housing relative to a plane perpendicular to the horizontal plane.

[0157] Step S2: Calculate the first beam radiation direction of the metasurface array using the beam deflection compensation module.

[0158] In some implementations, the first beam radiation direction of the metasurface array is determined based on the input of first direction information, first angle information, and second angle information. The method for determining the beam radiation direction is given in formulas (1) and (2) below:

[0159] θ=θ best -Δθ pitch (1);

[0160] φ=φ best -Δφ roll (2);

[0161] Where (θ, φ) represents the beam radiation direction, with the horizontal plane as the xy reference plane, the z-axis direction as the normal direction perpendicular to this plane, θ measured from the normal (z-axis), and φ measured from the x-axis in the xy plane; (θ best φ best ) represents the first direction information, Δθ pitch This refers to the radiation angle correction value generated by rotating the first housing around the axis of the electronic device, i.e., the first angle information; Δφ roll This refers to the radiation angle correction value generated by rotating the electronic device around a vertical line, i.e., the second angle information.

[0162] Step S3: Output the working parameters of the target metasurface unit through the phase codebook generation module.

[0163] In one example, the compensation phase of each metasurface unit in the metasurface array is determined by the phase codebook generation module, as shown in the following formula (3):

[0164] phase[m,n]=-ksinθ(x[m,n]cosφ+y[m,n]sinφ) (3);

[0165] Where k represents the wave number, k = 2π / λ, and λ represents the working wavelength of the electromagnetic wave in free space; if the metasurface antenna array is composed of M×N metasurface units of the same size, then (x[m,n], y[m,n]) is denoted as the physical coordinates of the (m,n)th metasurface unit in the metasurface array.

[0166] In some implementations, the target voltage corresponding to the compensation phase of each metasurface unit is looked up from a preset second mapping table; wherein, the second mapping table may be used to describe the correspondence between the compensation phase and the target voltage.

[0167] It should be noted that, in order for the antenna device to generate a signal beam in a specific direction, the electromagnetic waves radiated by the metasurface elements on the metasurface antenna array must be controlled so that the wavefront of the waves leaving the metasurface antenna array is a plane wave pointing in that specific direction. This means that when the electromagnetic waves radiate from different positions on the metasurface antenna array to a point in the far field, their path difference must be compensated so that the phases generated by all elements are added in phase, achieving energy convergence in the target direction. Therefore, in this application, it is necessary to determine the target voltage corresponding to each metasurface element. Thus, after determining the target voltage corresponding to each metasurface element, the target voltage corresponding to each metasurface element is applied to the adjustment element of each metasurface element through a control signal, so that the phase shift of each metasurface element is set to the required value at the instant it obtains its respective target voltage, thereby enabling the antenna device to generate a signal beam in a specific direction.

[0168] In one example, when the environmental perception data includes obstacle data and / or object data, and environmental signal monitoring result data, the obstacle data and / or object data are input into the frequency band optimization selection module, which determines the target frequency band. Based on the environmental signal monitoring result data and device shape data, the second beam radiation direction of the metasurface antenna array is calculated by the beam deflection compensation module. The second beam radiation direction and the target frequency band are input into the phase codebook generation module, which outputs the operating parameters of the target metasurface unit. The specific implementation process is described below, including steps S5 to S7:

[0169] Step S5: Determine the first target frequency band through the frequency band optimization selection module;

[0170] In some implementations, the type of approaching object or obstacle is determined based on obstacle data and / or object data; and a first target frequency band corresponding to the type is determined.

[0171] When environmental perception data includes obstacle data, the obstacle type is determined based on this obstacle data; then, a first target frequency band is determined based on this obstacle type. For example, if the obstacle is a wall, the obstacle data includes a target dielectric constant. The wall type is determined using the target dielectric constant and a third mapping table, where the third mapping table establishes the correspondence between wall types and dielectric constants. The first target frequency band is determined based on the wall type and a fourth mapping table, where the fourth mapping table establishes the correspondence between wall types and signal frequency bands. This scenario primarily involves obstacles between the target object or moving object and the electronic device, where the signal emitted by the antenna cannot penetrate the obstacle. By adjusting the parameters of the FMCW signal, the adjusted FMCW signal can penetrate the obstacle, enabling the detection of the target object or moving object behind the obstacle. This obstacle data can be determined based on a preset FMCW signal.

[0172] Alternatively, if the environmental perception data includes object data, the object type can be determined based on that object data; and the first target frequency band can be determined based on that object type. It is understood that this scenario primarily involves situations where there are no obstacles between the target object or moving object and the electronic device. In this way, by adjusting the parameters of the FMCW signal, the detection accuracy of the adjusted FMCW signal for the target object or moving object can be improved. The object data can be determined based on a preset FMCW signal.

[0173] Alternatively, when the environmental perception data includes object data and obstacle data, the object type and obstacle type are determined based on the object data; and the first target frequency band is determined based on the object type and obstacle type. It is understood that this scenario primarily involves situations where there are obstacles between the target object or moving object and the electronic device, and the signal emitted by the antenna device can penetrate the obstacles. Therefore, by adjusting the parameters of the FMCW signal, the adjusted FMCW signal can not only penetrate obstacles but also achieve higher detection accuracy for the target object or moving object.

[0174] Step S6: Calculate the second beam radiation direction of the metasurface array using the beam deflection compensation module;

[0175] Step S7: Output the working parameters of the target metasurface unit through the phase codebook generation module.

[0176] In some implementations, the second beam radiation direction and the first target frequency band are substituted into the above formula (3) to determine the compensation phase of each metasurface unit in the metasurface array. The first target frequency band is used to adjust the wavenumber in the above formula (3).

[0177] In some implementations, the target voltage corresponding to the compensation phase of each metasurface unit is looked up from a preset second mapping table.

[0178] In some implementations, when the environmental perception data includes monitoring data of the target (i.e., the attacker mentioned above), the third beam radiation direction of the metasurface antenna array is calculated based on the target monitoring data and device shape data using a beam deflection compensation module (or a destructive interference generation module). This third beam radiation direction and the target frequency band are then input into a phase codebook generation module, which outputs the operating parameters of the target metasurface unit. The specific implementation process is described below, including steps S8 to S10:

[0179] Step S8: Obtain attack target monitoring data and device form data;

[0180] Step S9: Calculate the third beam radiation direction of the metasurface array using the beam deflection compensation module (or destructive interference generation module);

[0181] In some implementations, the attack target monitoring data may include second direction information, which can be determined by the user through the human-computer interaction interface of the electronic device, or obtained by analyzing the FMCW signal emitted by the electronic device. The second direction information may refer to the direction from which electromagnetic leakage is to be suppressed, i.e., the direction from which the attacker is located, for example, the direction from which the hacker is located.

[0182] In some implementations, the third beam radiation direction of the metasurface array is determined based on the second direction information, the first angle information, and the second angle information input. The method for determining the beam radiation direction is given in formulas (4) and (5) below:

[0183] θ=θ null -Δθ pitch (4)

[0184] φ=φ null -Δφ roll (5)

[0185] Where, (θ null φ null ) indicates information in the second direction.

[0186] Step S10: Output the working parameters of the target metasurface unit through the phase codebook generation module.

[0187] It should be noted that steps S1 to S4 can be used to determine the working parameters of the first working mode, steps S5 to S7 can be used to determine the working parameters of the second working mode, and steps S8 to S10 can be used to determine the working parameters of the third working mode.

[0188] In this embodiment, by introducing device form and environmental perception data to dynamically optimize the control signal, and by taking into account changes in the actual use environment, more accurate and efficient antenna parameter adjustment is achieved, enhancing the system's adaptability to external conditions.

[0189] In some embodiments, step S530 may be included before step S500:

[0190] Step S530: In response to the target triggering event, control the antenna device to switch from the current operating mode to the target operating mode that matches the target triggering event;

[0191] The target operating mode includes at least one of communication mode, perception mode, and stealth mode;

[0192] The target triggering event is generated from at least one of the following:

[0193] The electronic device moves to the target area;

[0194] Obtain target configuration data that is applied to electronic devices;

[0195] The electronic device establishes a target communication connection with the first device;

[0196] The device form of electronic equipment has changed;

[0197] The relative positional relationship between the electronic device and the second device is switched to the first relative positional relationship;

[0198] The application running on the electronic device switches from the first type of application to the second type of application.

[0199] In some implementations, moving an electronic device to a target area can mean that the electronic device enters an area with weak ground base station signals, or that the electronic device enters an area where sensing and detection are required, or that the electronic device enters a conference room.

[0200] In some implementations, the target configuration data may be generated by the user interacting with the electronic device, for example, by the user interacting with the electronic device through specific buttons, voice commands, gesture commands, shortcut keys, combination keys, etc.

[0201] In some implementations, the electronic device establishes a target communication connection with the first device, allowing the electronic device to determine a target operating mode based on the task being performed by the first device. For example, when the first device is performing a first task, the target operating mode is determined to be a communication mode. The first task can be one or more of the following: a meeting task, a video call task, a photo sending task, or a video sending task.

[0202] In some implementations, after the electronic device establishes a target communication connection with the first device, switching the network connection mode of the electronic device can trigger a target-triggered event. For example, the electronic device switches from a wireless local area connection mode to a hotspot sharing mode.

[0203] In some implementations, the device form of the electronic device is switched, which may be that the first housing is switched to a state at a preset angle with the host system body, for example, a laptop computer changes from a closed state to an open state.

[0204] In some implementations, switching the relative positional relationship between the electronic device and the second device to the first relative positional relationship means that the positional relationship between the electronic device and other devices changes. For example, the electronic device enters a distance that other devices can detect. In this scenario, the target working mode can refer to stealth mode.

[0205] In some implementations, the application running on the electronic device is switched from a first type of application to a second type of application, where the second type of application may be an application that requires high bandwidth data transmission, such as a conferencing application or a video call application.

[0206] Through the various types of triggering events mentioned above, the system can intelligently switch the working mode of the antenna device in different usage scenarios to better meet user needs while improving the overall energy efficiency and safety of the equipment.

[0207] In this embodiment, by defining multiple possible triggering events and associating them with corresponding operating modes, automated switching control of the antenna device is achieved. This mechanism can automatically adjust the antenna function based on user behavior, device status, or environmental changes, improving the system's intelligence and convenience, and providing users with a smoother operating experience.

[0208] The following describes the application of the embodiments of this application in a real-world scenario.

[0209] Traditional laptop antennas typically use PIFA (planar inverted-F antenna), Loop (loop antenna), or Slot (slot antenna) types. These antennas are usually placed at the laptop hinge, on the non-metallic bezel below or on the screen, or in the metal casing through a window / slot. Due to the limited internal space and position of the antenna, the radiation pattern of the antenna is fixed and it does not have spatial scanning capability, making it impossible to achieve antenna array arrangement and dynamic beam control.

[0210] Existing barrier sensing technology has some application in fixed scenarios such as base stations. These scenarios have ample space to accommodate metasurface antenna arrays, complex control circuits, and power supply modules, eliminating concerns about size and weight. Furthermore, since base stations are typically stationary, their beams usually only need to point in a few fixed directions (e.g., covering a single sector), requiring no high-speed, real-time dynamic response. However, for mobile devices, such as laptops, which users frequently carry and rotate, the antenna beam direction is constantly changing. There is insufficient space to accommodate metasurface antenna arrays. Therefore, applying metasurface antenna arrays to mobile devices cannot reuse the device's WiFi communication module and system computing power, requiring additional equipment (dedicated transceiver antennas, RF chips, processors, etc.) on the mobile device, resulting in resource waste and increased costs.

[0211] Furthermore, the electronic components inside a laptop (especially the keyboard controller, CPU, and various data cables) emit weak electromagnetic waves due to rapid changes in current during operation. This radiation is unintentional but carries information being processed. Attackers can use a tuned directional antenna and a highly sensitive receiver from several meters or even tens of meters away to capture this weak electromagnetic radiation. They can then analyze and reconstruct the user's complete input, including passwords, chat logs, and confidential document content, using machine learning algorithms—a phenomenon known as electromagnetic side-channel attack—which poses a significant threat to user information privacy and security.

[0212] Based on this, embodiments of this application provide an antenna system and a control method for the antenna system applied in mobile devices such as laptops. Specifically, it relates to a hardware and software system that integrates a metasurface array antenna on the A-side shell (i.e., the back cover of the screen) of a laptop to achieve beam-controllable communication, non-line-of-sight environmental perception, and electromagnetic privacy protection, thereby solving the problems of fixed radiation patterns and single functions of traditional terminal antennas.

[0213] First, the structural design of the mobile terminal will be explained.

[0214] like Figure 3 As shown, the metasurface antenna array is integrated into the A-side shell (i.e., the first shell) of the laptop using a "sandwich" structure, comprising a wave-transparent decorative protective layer (i.e., the protective layer), a metasurface layer (i.e., the antenna element layer), a control layer, and a substrate layer stacked sequentially downwards.

[0215] The functions of a translucent decorative protective layer can include:

[0216] 1) Physical protection: The material of the wave-transparent decorative protective layer has a certain structural strength, which enables the wave-transparent decorative protective layer to provide wear-resistant, scratch-resistant and impact-resistant physical protection for the antenna system (i.e., the antenna system). Therefore, a certain structural strength is required.

[0217] 2) Electromagnetic window: The material of the translucent decorative protective layer needs to be considered from two dimensions: material selection and thickness. When making the translucent decorative protective layer, it is necessary not only to allow electromagnetic waves to pass through the translucent decorative protective layer efficiently, but also to ensure that the transmittance of electromagnetic waves is greater than 90%, so that electromagnetic waves have extremely low electromagnetic loss in the target frequency band (such as Wi-Fi 2.4 / 5 / 6GHz) when passing through the translucent decorative protective layer.

[0218] 3) Decoration: Spray colors, personalized coatings, and integrate brand logos on the transparent decorative protective layer. By covering the antenna system with the transparent decorative protective layer, the antenna system becomes "invisible" in appearance and does not affect the overall appearance design of the mobile device.

[0219] The metasurface layer is fabricated using flexible printed circuit board technology and includes a metasurface antenna array, varactor diodes (adjustment elements), and a control line network.

[0220] 1) Metasurface antenna array: Periodic or quasi-periodic subwavelength structures (such as C-shaped, I-shaped, square open ring, etc.) are formed by etching metal (usually copper) onto an FPC. These structures are the basic resonant units (i.e., metasurface units) for radiating and receiving electromagnetic waves.

[0221] 2) Varactor diode: Each resonant unit integrates a miniature varactor diode. It can be understood that the varactor diode is the key to realizing electromagnetic reconfigurability. In practice, by applying a reverse bias voltage to the varactor diode, the junction capacitance of the varactor diode is changed, thereby continuously and analogously changing the resonant frequency and phase response of the entire resonant unit.

[0222] 3) Control Line Grid: An active matrix grid is formed through fine metal traces. The control lines in each row and column of this active matrix grid are used for addressing and providing an independent bias voltage to the varactor diodes of each resonant unit.

[0223] The control layer is another FPC layer that is electrically connected to the control line grid in the metasurface layer. Its specific structure and functions include:

[0224] 1) Driver circuit integration: Integrate key miniaturized driver components, such as digital-to-analog converters and operational amplifiers.

[0225] 2) Power and signal distribution: Distribute the low-voltage DC power and control signals from the motherboard to the entire metasurface antenna array.

[0226] The substrate layer provides mechanical support for the metasurface layer, the wave-transparent decorative protective layer, and the control layer.

[0227] Next, the control method of the antenna system will be explained. Specifically, the laptop's built-in metasurface control chip (i.e., control module) implements three core functional modes, and the system architecture is as follows: Figure 6 As shown, it mainly includes communication mode, perception mode and stealth mode. Communication mode is enabled in real time by the mobile device, while perception mode and stealth mode are optional modes.

[0228] The main implementation process of the communication mode may include steps S601 to S604:

[0229] Step S601: Monitor the strength / direction of environmental signals;

[0230] Here, the ambient signal strength is determined by monitoring the average radiated power of cellular network or WiFi signals. By analyzing the signal strength of cellular network or WiFi signals, the first direction information of the strongest incoming signal can be determined, and this first direction information is used to confirm the direction of the optimal communication transmission link.

[0231] Step S602: Update the metasurface coding configuration in real time;

[0232] Here, based on the first direction information determined in step S601, the first encoding information for controlling the metasurface is determined.

[0233] Step S603: Dynamically adjust the direction of the radiation beam;

[0234] Here, based on the first encoded information, the radiation beam direction of the metasurface antenna array is dynamically adjusted to establish an optimal communication transmission link.

[0235] Step S604: Directed high-speed data transmission.

[0236] Here, after establishing the optimal transmission link, high-speed transmission of communication data of the device can be achieved.

[0237] The main implementation process of the perception mode may include steps S611 to S614:

[0238] Step S611: Transmit FMCW detection signal;

[0239] Here, in the perception mode, there are two scenarios: wall-mounted target detection and moving object detection. When performing wall-mounted target detection or moving object detection, the metasurface antenna array is controlled to transmit FMCW detection signals. Before transmitting the FMCW detection signals, the parameter information of the transmitted FMCW detection signals needs to be determined in advance. For example, in the scenario of wall-mounted target detection, where there is a wall obstructing the target object and the mobile device, the parameter information for transmitting the FMCW detection signals can be determined based on the characteristics of the wall.

[0240] Step S612: Echo reception;

[0241] Here, the echo of the transmitted FMCW probe signal is received.

[0242] Step S613: Doppler analysis;

[0243] Here, Doppler analysis is performed on the received echo.

[0244] Step S614: Output the detection results such as movement speed / heart rate.

[0245] Here, after performing Doppler analysis on the echo, results such as the target object's movement speed and heart rate can be output.

[0246] The main implementation process of stealth mode may include steps S621 to S624:

[0247] Step S621: Predict / detect the attacker's direction;

[0248] Here, the estimated attacker direction can be the attacker direction input by the user through the interactive interface of the mobile device (i.e., the second direction information). The perceived attacker direction can be obtained by analyzing the echo of the emitted FMCW probe signal.

[0249] Step S622: Update the metasurface coding configuration in real time;

[0250] Here, based on the attacker direction information determined in step S622, the second encoding information for controlling the metasurface is determined.

[0251] Step S623: Form a destructive interference with the system's leaked electromagnetic waves;

[0252] Here, based on the second encoded information, the direction of the antenna's radiation beam is dynamically adjusted so that the electromagnetic waves radiated by the metasurface array and the electromagnetic waves leaked by the system (carrying user privacy information) cancel each other out in the direction of the attacker, forming destructive interference, which ultimately prevents the attacker from capturing effective information.

[0253] Step S624: Achieve stealth protection.

[0254] Here, the electromagnetic stealth of mobile devices is achieved by dynamically disrupting and reshaping the beam pattern of electromagnetic leakage radiation through the destructive interference of electromagnetic waves, making them impossible for attackers to effectively receive and decode.

[0255] In traditional materials, the phase change of an electromagnetic wave wavefront depends on the propagation distance (e.g., the continuous accumulation in a homogeneous refractive index medium). Taking free space as an example, after an electromagnetic wave propagates a distance r in free space, the phase change φ of its wavefront is:

[0256]

[0257] Where φ represents the phase change in radians; λ represents the wavelength of the electromagnetic wave in free space in meters; r represents the propagation distance in meters; k represents the wave number, which is the phase change per unit length in radians per meter, and the negative sign indicates phase delay.

[0258] The metasurface layer in this application can introduce discrete phase abrupt changes (0 to 2π full coverage) in an extremely thin layer through a subwavelength structure. By arranging resonant units of different structures or sizes, a fixed phase difference is generated between adjacent resonant units, thereby forming an equivalent phase gradient at the radiation interface. This is the gradient phase control principle of metamaterials and the core of the algorithm in the embodiments of this application.

[0259] Below, refer to Figure 7 As shown, the core processes of the above communication mode, perception mode and stealth mode are explained.

[0260] The main implementation process of the communication mode may include steps S701 to S705:

[0261] S701: Environmental Signal Monitoring / IMU Attitude Sensor

[0262] Here, by monitoring environmental signals, the optimal signal transmission direction of the environment in which the electronic device is located can be output in real time, which is the first direction information mentioned above.

[0263] The IMU attitude sensor can acquire the position / tilt information of the output electronic device. The tilt information refers to the tilt angle of the laptop's A-shell relative to the horizontal plane (i.e., the first angle information mentioned above), and the position information refers to the rotation angle of the laptop's A-shell relative to the reference plane (i.e., the second angle information mentioned above).

[0264] S702: Beam deflection compensation module;

[0265] Here, the first direction information, tilt information and position information are input into the beam deflection compensation module. The beam deflection compensation module substitutes the input information into the above formulas (1) and (2) to obtain the first beam radiation direction of the metasurface array.

[0266] S703: FPGA phase codebook generation;

[0267] Here, the first beam radiation direction of the obtained metasurface array is input into the phase codebook generation module. The phase codebook generation module substitutes this information into the above formula (3) to obtain the compensation phase of each metasurface unit in the metasurface array, and generates and stores the first phase codebook.

[0268] It should be noted that, in this application, to form a beam with a specific direction, the electromagnetic waves radiated by all metasurface units on the metasurface array must have a wavefront pointing in that specific direction when they leave the array. This means that when the electromagnetic waves radiate from different positions on the array surface to a point in the far field, their path difference must be compensated so that the phases generated by all units are added in phase, achieving energy convergence in the target direction. Therefore, it is necessary to determine the compensation phase of each metasurface unit in the metasurface array.

[0269] In some implementations, a look-up table (LUT) for "compensation phase-control voltage value" is pre-stored in the FPGA, so that the first control voltage to be applied to each metasurface unit can be obtained based on the first phase codebook and the look-up table for "compensation phase-control voltage value".

[0270] S704: Metasurface array driver;

[0271] In some implementations, after determining the required first control voltage for each metasurface unit, the control layer drives the control lines in the control line grid to apply these first control voltages sequentially and precisely to the varactor diodes of each metasurface unit. Thus, at the instant all metasurface units receive their respective first control voltages, their phase shifts are set to the desired values. This allows for beam direction control of the entire metasurface antenna array through coordinated operation.

[0272] S705: Reconfigurable metasurface antenna array.

[0273] Here, the reconstruction of the metasurface array can be achieved when each metasurface unit obtains its own first control voltage.

[0274] The main implementation process of the perception mode may include steps S711 to S717:

[0275] Step S711 corresponds to step S701 above: environmental signal monitoring / IMU attitude sensor;

[0276] Step S712 corresponds to step S702 above: beam deflection compensation module;

[0277] S713: Target Database / Wall Database

[0278] The target database mainly stores feature classification data of target types, such as human body (heart rate, movement speed, physical characteristics, etc.), pets, and machinery and equipment.

[0279] The wall database primarily stores wall characteristic data such as dielectric constant, thickness, height, and corresponding penetrable frequencies. Example of wall dielectric constant: brick wall ε = 4.5; concrete ε = 6.

[0280] S714: Frequency band selection logic: Sensing target type / wall type;

[0281] Here, by analyzing the received signal, we can obtain the signal's characteristic data, which can then be compared with the target database / wall database to determine the type information corresponding to the characteristic data.

[0282] For example, a known and controllable probe beam is emitted towards the wall using a metasurface array, and the returned beam is received. The returned beam is analyzed to obtain its amplitude and phase information. The target dielectric constant of the wall is then determined using the amplitude and phase information, and compared with the dielectric constant in the wall database to determine the type of the wall.

[0283] S715: Frequency band optimization selection module;

[0284] Here, the wall type is input into the frequency band optimization selection module. The frequency band optimization selection module compares the wall type with the stored third mapping table to determine the first target frequency band. For example, when the wall type is brick, the first target frequency band can be 5.15-5.35GHz; when the wall type is concrete, the first target frequency band can be 2.4-2.5GHz.

[0285] Step S716 corresponds to step S703 above: FPGA phase codebook generation;

[0286] Here, the second beam radiation direction of the metasurface array obtained through step S712 and the first target frequency band are input into the phase codebook generation module. The phase codebook generation module substitutes this information into the above formula (3) to obtain the compensation phase of each metasurface unit in the metasurface array, and generates and stores the second phase codebook.

[0287] In some implementations, a lookup table of "compensation phase-control voltage value" is pre-stored in the FPGA, so that the second control voltage to be applied to each metasurface unit can be obtained according to the second phase codebook and the lookup table of "compensation phase-control voltage value".

[0288] Step S717 corresponds to step S704 above: Metasurface array driving.

[0289] In some implementations, after determining the required second control voltage for each metasurface element, the control layer drives the control lines in the control line grid to apply these second control voltages sequentially and precisely to the varactor diodes of each metasurface element. The phase offset of all metasurface elements is set to the desired value the instant they receive their respective second control voltages. Thus, by working collaboratively across the entire metasurface antenna array, beam direction control of the metasurface antenna array can be achieved.

[0290] Step S717 corresponds to step S705 above: reconfigurable metasurface antenna array.

[0291] Here, the metasurface antenna array can be reconfigured when each metasurface element obtains its own second control voltage.

[0292] The main implementation process of stealth mode may include steps S731 to S735:

[0293] Step S731: Electromagnetic stealth target monitoring;

[0294] Here, the electromagnetic stealth target is the attacker described above. Thus, by monitoring the electromagnetic stealth target, the attacker's direction information can be obtained.

[0295] S732: Destructive interference generation module;

[0296] Here, the attacker's direction information, tilt information and position information are input into the destructive interference generation module. The destructive interference generation module substitutes the input information into the above formulas (4) and (5) to obtain the third beam radiation direction of the metasurface array.

[0297] Step S733 corresponds to step S703 above: FPGA phase codebook generation;

[0298] Here, the third beam radiation direction of the obtained metasurface array is input into the phase codebook generation module. The phase codebook generation module substitutes this information into the above formula (3) to obtain the compensation phase of each metasurface unit in the metasurface array, and generates and stores the third phase codebook.

[0299] In some implementations, a lookup table of "compensation phase-control voltage value" is pre-stored in the FPGA, so that the third control voltage to be applied to each metasurface unit can be obtained according to the third phase codebook and the lookup table of "compensation phase-control voltage value".

[0300] Step S734 corresponds to step S704 above: metasurface array driving;

[0301] In some implementations, after determining the required third control voltage for each metasurface unit, the control layer drives the control lines in the control line grid to apply these third control voltages sequentially and precisely to the varactor diodes of each metasurface unit. The phase offset of all metasurface units is set to the desired value the instant they receive their respective third control voltages. Thus, by working collaboratively across the entire metasurface array, beam direction control of the metasurface array can be achieved.

[0302] Step S735 corresponds to step S705 above: reconfigurable metasurface array.

[0303] Here, the reconstruction of the metasurface array can be achieved when each metasurface unit obtains its own third control voltage.

[0304] Finally, taking the sensing mode as an example, the interaction between the components in the antenna system and the interaction between the antenna system and other components in the electronic device are explained, such as... Figure 8 As shown, steps S801 to S804 may be included:

[0305] Step S801: The metasurface antenna array transmits FMCW detection signals into the environment;

[0306] Here, the FMCW detection signal is obtained from step S717 above, and the environment refers to the current environment of the electronic device.

[0307] Step S802: The metasurface antenna array receives the target echo transmitted from the environment;

[0308] Here, after the metasurface antenna array receives the target echo, it converts the electromagnetic wave into an electrical signal.

[0309] Step S803: The metasurface antenna array sends electrical signals to the signal processing system;

[0310] Here, the metasurface antenna array sends the electrical signal to the signal processing system, which performs Doppler analysis on the electrical signal to obtain the target characteristic parameters.

[0311] Step S804: The signal processing system sends the target feature parameters to the user interface.

[0312] Here, target feature parameters may include one or more of the following: breathing, heart rate, movement rate, and the type of the target object, etc.

[0313] In some implementations, the user interface displays the target feature parameters on the interface.
