[0041] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and do not limit the scope of protection of this disclosure.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure.

[0043] Currently, mobile phones and tablets have become indispensable technological products in people's lives, studies, and entertainment, bringing them numerous conveniences and enjoyment. With the diversification of terminal functions, there are now many types and brands of terminals available, offering consumers a wide range of choices. Simply improving the functional features of terminals is no longer sufficient to meet people's demands.

[0044] In related technologies, as the interconnection and interaction scenarios between terminals and functional devices (such as charging devices, computers, camera modules, etc.) increase, users are demanding higher and higher communication performance after the interconnection. Traditionally, the conventional solution for transmitting information (photos / videos / files) from terminals to functional devices (such as charging devices, computers, camera modules, etc.) uses wired DP / HDMI / MIPI methods, which are inconvenient to use and have low transmission / synchronization rates. Traditional Bluetooth wireless connections also suffer from long latency and slow transmission rates. This is detrimental to improving the interactive experience between terminals and functional devices.

[0045] Based on this, the present disclosure provides an electronic device that enables ultra-short-range communication with low latency and high transmission rate, thereby enabling the establishment of a reliable transmission link between the terminal and the functional device and improving the interactive experience between the terminal and the functional device.

[0046] To better understand the electronic device of this disclosure, it will be described below in conjunction with the accompanying drawings.

[0047] like Figure 1 as well as Figure 2 As shown in the embodiments of this disclosure, an electronic device is provided, including a terminal 10 and a functional device 20. The terminal 10 includes a back surface 110 and a first antenna assembly 200 disposed on the back surface 110, the first antenna assembly 200 operating in the extremely high frequency band. The functional device 20 includes a contact surface 21 for contacting the terminal 10 and a second antenna assembly 22 disposed on the contact surface 21, the second antenna assembly 22 operating in the extremely high frequency band. When the back surface 110 is disposed on the contact surface 21, the first antenna assembly 200 and the second antenna assembly 22 are communicatively connected.

[0048] When terminal 10 establishes a communication connection with functional device 20, the back surface 110 of terminal 10 is positioned on the contact surface 21 of functional device 20, so that the first antenna assembly 200 is positioned as close as possible to the second antenna assembly 22. Both the first antenna assembly 200 and the second antenna assembly 22 operate in the extremely high frequency band. When they are connected, they can achieve ultra-short-range communication with low latency and high transmission rate, enabling a reliable transmission link to be established between terminal 10 and functional device 20.

[0049] It should be noted that the extremely high frequency (EHF) band has a frequency range of 30 GHz to 300 GHz and a wavelength of 1 mm to 1 cm. It is characterized by short wavelength, large bandwidth, and high-speed data transmission.

[0050] In some embodiments, the extremely high frequency band is greater than or equal to 60 GHz. This enables data transmission speeds of multiple gigabits per second, allowing for real-time transmission of 4K or even 8K video streaming and large-scale data files.

[0051] In some embodiments, the functional device 20 includes at least one of a wireless charging device, a camera module, a computer, a television, a projector, a smartphone stand, and a smart cockpit base. Thus, when the terminal 10 exchanges data with different functional devices 20, the technology disclosed herein enables high-speed end-to-end information transmission, with a transmission rate of 3.6Gbps to 8Gbps, ensuring that the transmission link loss between them is better than -15dB.

[0052] For example, such as Figure 1 As shown, when the functional device 20 is a wireless charging device, end-to-end information transmission can be achieved using the technology of this disclosure. In this case, the contact surface 21 can support the terminal 10.

[0053] For example, such as Figure 4 As shown, when the functional device 20 is a camera module, the technology disclosed herein enables lossless and rapid transmission of high-definition, high-quality photos from the camera module to the terminal 10, allowing for quick acquisition of higher-resolution, high-quality photos and a better interactive experience. (Refer to...) Figure 4 As shown, the back surface 110 is in contact with the contact surface 21.

[0054] For example, when the functional device is a computer, the technology disclosed herein can be used to achieve lossless and rapid transmission of high-definition, high-quality photos and large-scale data files from the terminal to the computer, enabling quick acquisition of relevant data from the terminal and providing a good interactive experience. In this case, the contact surface can support the terminal.

[0055] For example, when the functional device is a television or projector, the technology disclosed herein can be used to achieve lossless and rapid transmission of high-definition / high-quality photos from the terminal to the computer, thereby quickly obtaining high-quality photos with higher pixel counts and a better interactive experience.

[0056] For example, when the functional device is a smartphone holder in a smart car or a base in a smart cockpit, the technology disclosed herein can be used to achieve wireless, lossless, high-definition image projection to an extended screen (such as an in-vehicle display or in-vehicle projection screen), providing a good interactive experience. In this case, the contact surface can support the terminal.

[0057] Optionally, in some embodiments, the first antenna assembly includes at least one of a microstrip patch antenna, a dipole antenna, and a cavity antenna. This allows the first antenna assembly to be flexibly arranged on the terminal.

[0058] Optionally, in some embodiments, the second antenna assembly includes at least one of a microstrip patch antenna, a dipole antenna, and a cavity antenna. This allows the second antenna assembly to be flexibly arranged on the functional device.

[0059] Understandably, the structures of the first antenna assembly and the second antenna assembly can be the same or different, as long as low transmission loss is achieved, in order to improve the flexibility of antenna arrangement.

[0060] like Figure 1 or Figure 4 As shown, in some embodiments, when the back surface 110 is disposed on the abutment surface 21, the back surface 110 abuts against the abutment surface 21, and on the front projection surface of the back surface 110, at least part of the first antenna assembly 200 and the second antenna assembly 22 overlap. This further shortens the transmission distance between the first antenna assembly 200 and the second antenna assembly 22, enabling point-to-point ultra-short-range wireless connection.

[0061] It should be noted that the number of antennas in the first antenna assembly 200 corresponds one-to-one with the number of antennas in the second antenna assembly 22, and includes at least one antenna.

[0062] like Figures 1 to 3 As shown, or Figures 4 to 6 As shown, in some embodiments, the first antenna assembly 200 includes a first antenna 210 operating in the extremely high frequency band, and the second antenna assembly 22 includes a second antenna 22a operating in the extremely high frequency band. When the back surface 110 is disposed on the contact surface 21, the first antenna 210 and the second antenna 22a are communicatively connected. Thus, when the terminal 10 communicates with the functional device 20, the back surface 110 of the terminal 10 is disposed on the contact surface 21 of the functional device 20, so that the first antenna 210 is placed as close as possible to the second antenna 22a. Since both the first antenna 210 and the second antenna 22a operate in the extremely high frequency band, when they are communicatively connected, they can achieve ultra-short-range communication with low latency and high transmission rate, enabling a reliable transmission link to be established between the terminal 10 and the functional device 20.

[0063] like Figure 1 as well as Figure 3 As shown, when the functional device 20 is a wireless charging dock, the first antenna 210 and the second antenna 22a are communicatively connected, enabling data transmission between the terminal 10 and the wireless charging dock. Figure 3The simulation results of the transmission link loss (S12 / S21) and reflection coefficient (S11 / S22) shown in the figure show that the transmission link loss (S12 / S21) at 60GHz (i.e., m1) is approximately -14.4dB (>-15dB), which enables ultra-short-range communication with low latency and high transmission rate, allowing a reliable transmission link to be established between terminal 10 and functional device 20.

[0064] like Figure 4 as well as Figure 6 As shown, when the functional device 20 is a camera module, the first antenna 210 and the second antenna 22a are communicatively connected, enabling data transmission between the terminal 10 and the camera module. Figure 6 The simulation results of the transmission link loss (S34 / S43) and reflection coefficient (S33 / S44) shown in the figure show that the transmission link loss (S34 / S43) at 60GHz (i.e., m1) is approximately -14.7dB (>-15dB), which enables ultra-short-range communication with low latency and high transmission rate, allowing a reliable transmission link to be established between terminal 10 and functional device 20.

[0065] Optionally, such as Figure 4 as well as Figure 5 As shown, in some embodiments, one of the contact surface 21 and the back surface 110 is provided with a magnetic suction member 23, and the other is provided with a mating member 300 that magnetically engages with the magnetic suction member 23. In this way, through the magnetic engagement of the magnetic suction member 23 and the mating member 300, the functional device 20 (e.g., a camera module) can be easily magnetically fixed to the back surface 110 of the terminal 10, realizing reliable alignment between the first antenna assembly 200 and the second antenna assembly 22, and improving the stability of the communication connection between the terminal 10 and the functional device 20.

[0066] Furthermore, such as Figure 7 as well as Figure 8As shown, in some embodiments, the first antenna assembly 200 further includes a third antenna 220 operating in the extremely high frequency band, the third antenna 220 being spaced apart from the first antenna 210. The second antenna assembly 22 further includes a fourth antenna 22b operating in the extremely high frequency band, the fourth antenna 22b being spaced apart from the second antenna 22a. When the back surface 110 is disposed on the contact surface 21, the first antenna 210 is communicatively connected to the second antenna 22a, and the third antenna 220 is communicatively connected to the fourth antenna 22b. Thus, when the terminal 10 communicates with the functional device 20, the back surface 110 of the terminal 10 is disposed on the contact surface 21 of the functional device 20, and the third antenna 220 is disposed as close as possible to the fourth antenna 22b. Both the third antenna 220 and the fourth antenna 22b operate in the extremely high frequency band. When they are connected, they can achieve ultra-short-range communication with low latency and high transmission rate. As a result, the terminal 10 and the functional device 20 can establish a transmission link between the two pairs of antennas through the communication connection between the first antenna 210 and the second antenna 22a, as well as the communication connection between the third antenna 220 and the fourth antenna 22b, thereby further improving the transmission rate and the reliability of the communication connection.

[0067] like Figure 7 As shown, in some embodiments, on the frontal projection plane of the back side 110, the first antenna 210 and the second antenna 22a at least partially overlap, and the third antenna 220 and the fourth antenna 22b at least partially overlap. This further shortens the transmission distance between the first antenna 210 and the second antenna 22a, as well as the transmission distance between the third antenna 220 and the fourth antenna 22b, enabling point-to-point ultra-short-range wireless connections.

[0068] like Figure 8 As shown, in some embodiments, the effective radiation length direction of the first antenna 210 intersects with the effective radiation length direction of the third antenna 220, and the effective radiation length direction of the second antenna 22a intersects with the effective radiation length direction of the fourth antenna 22b. This effectively prevents mutual interference between the first antenna 210 and the third antenna 220, as well as between the second antenna 22a and the fourth antenna 22b, resulting in good isolation between the antennas.

[0069] It should be noted that the term "intersection" in this disclosure includes both planar intersection and non-planar intersection. That is, on the orthographic projection plane perpendicular to the back surface, the effective radiation length of the first antenna 210 and the effective radiation length of the second antenna 220 intersect.

[0070] In some embodiments, the effective radiation length direction of the first antenna is perpendicular to the effective radiation length direction of the third antenna, and the effective radiation length direction of the second antenna is perpendicular to the effective radiation length direction of the fourth antenna. Thus, the first and third antennas are placed at a 90° angle to each other, and the second and fourth antennas are also placed at a 90° angle, effectively improving the isolation between the antennas.

[0071] The terminal excites the first and third antennas in the -45° / 45° direction, and the functional device excites the second and fourth antennas in the 45° / -45° direction.

[0072] like Figure 9 As shown in the figure, the simulation results of the transmission link loss and isolation of two pairs of antennas are given. It can be seen from the figure that the transmission link loss (S12 / S34) between each pair of antennas is about -14.7dB (>-15dB) at 60GHz, and the isolation (S13 / S24) between the two antennas in the terminal 10 or the functional device 20 is less than -50dB. This enables ultra-short-range communication with low latency and high transmission rate, so that a reliable transmission link can be established between the terminal 10 and the functional device 20.

[0073] In other embodiments, the first antenna assembly 200 and the second antenna assembly 22 have at least three antennas.

[0074] like Figure 7 as well as Figure 8 As shown, in some embodiments, the contact surface 21 is provided with a positioning part 24 that engages with the terminal 10. When the back surface 110 is disposed on the contact surface 21, the terminal 10 engages with the positioning part 24 to make the first antenna 210 coincide with the second antenna 22a, and the third antenna 220 coincide with the fourth antenna 22b. In this way, by engaging with the terminal 10 through the positioning part 24, it is easy to achieve the alignment and coincidence of the first antenna 210 and the second antenna 22a, as well as the alignment and coincidence of the third antenna 220 and the fourth antenna 22b, thereby improving the stability of the point-to-point communication connection between the terminal 10 and the functional device 20.

[0075] Optionally, such as Figure 2 , Figure 5 or Figure 8 As shown, in some embodiments, the terminal 10 includes a rear cover 100 with a back surface 110, and the first antenna assembly 200 is fixed to the rear cover 100. In this way, by integrating the first antenna assembly 200 through the rear cover 100, interference from other antennas of the terminal 10 to the first antenna assembly 200 can be reduced, antenna clearance can be ensured, and the communication quality of the first antenna assembly 200 can be improved.

[0076] The terminals disclosed herein include handheld devices, vehicle-mounted devices, wearable devices, monitoring devices, smartphones, tablets, cameras, and other devices with communication functions.

[0077] Reference Figure 10 As shown, in some embodiments, terminal 10 further includes at least one or more of the following components: processing component 11, memory 12, power supply component 13, multimedia component 14, audio component 15, input / output interface 16, sensor component 17, and communication component 18.

[0078] The processing component typically controls the overall operation of the terminal, such as operations associated with display, telephone calls, data communication, camera operation, and recording. The processing component includes at least one or more processors to execute instructions to complete all or part of the steps of the methods described above. Furthermore, the processing component includes at least one or more modules to facilitate interaction between the processing component and other components. For example, the processing component may include at least a multimedia module to facilitate interaction between the multimedia component and the processing component.

[0079] The memory is configured to store various types of data to support operation on the terminal. Examples of this data include instructions for any application or method operating on the terminal, contact data, phonebook data, messages, pictures, videos, etc. The memory can be implemented by any type of volatile or non-volatile storage device or a combination thereof, such as static random access memory, read-only memory, magnetic storage, flash memory, disk, or optical disk.

[0080] The power supply unit provides power to the various components of the terminal. The power supply unit includes at least a power management system, one or more power supplies, and other components associated with generating, managing, and distributing power to the terminal.

[0081] The multimedia component includes the display module of this disclosure, facilitating human-computer interaction. If the display module includes a touch panel, the display module can be implemented as a touchscreen to receive input signals from the user. The touch panel includes one or more touch sensors to sense touches, swipes, and gestures on the touch panel. The touch sensors can sense not only the boundaries of touch or swipe actions but also the duration and pressure associated with the touch or swipe operation. In some embodiments, the multimedia component includes a front-facing camera and / or a rear-facing camera. When the terminal is in an operating mode, such as a shooting mode or a video mode, the front-facing camera and / or the rear-facing camera can receive external multimedia data. Each front-facing camera and rear-facing camera can be a fixed optical lens system or have focal length and optical zoom capabilities.

[0082] The audio component is configured to output and / or input audio signals. For example, the audio component includes a microphone (MIC) configured to receive external audio signals when the terminal is in an operating mode, such as call mode, recording mode, or voice recognition mode. The received audio signals may be further stored in memory or transmitted via a communication component. In some embodiments, the audio component also includes a speaker for outputting audio signals.

[0083] The input / output interface provides an interface between the processing component and the peripheral interface module, which can be a keyboard, click wheel, buttons, etc. These buttons may include, but are not limited to: home button, volume buttons, start button, and lock button.

[0084] The sensor assembly includes one or more sensors for providing state assessments of various aspects of the terminal. For example, the sensor assembly can detect the terminal's on / off state, the relative positioning of components such as the terminal's display and keypad, changes in the position of the terminal or a component of the terminal, the presence or absence of user contact with the terminal, the terminal's orientation or acceleration / deceleration, and temperature changes. The sensor assembly includes at least a proximity sensor configured to detect the presence of nearby objects without any physical contact. The sensor assembly also includes at least a photosensitizing element, such as a CMOS or CCD image sensor, for use in imaging applications. In some embodiments, the sensor assembly also includes at least an accelerometer, a gyroscope, a magnetometer, a pressure sensor, or a temperature sensor.

[0085] The communication component is configured to facilitate wired or wireless communication between the terminal and other devices. The terminal can access wireless networks based on communication standards, such as WiFi, 2G, 3G, 4G, or 6G, or combinations thereof. In one exemplary embodiment, the communication component receives broadcast signals or broadcast-related information from an external broadcast management system via a broadcast channel.

However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0087] The above embodiments are merely illustrative of several implementation methods of this disclosure, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the utility model patent.
