[0002] The Global Positioning System (GPS) is closely related to daily life. Highly directional antennas, such as narrow-beamwidth array antennas or parabolic antennas, can concentrate energy in a specific direction, reducing multipath effects and noise interference, and improving the accuracy of angle measurements, such as Angle of Arrival (AOA) positioning accuracy. To achieve better positioning, in user application scenarios, electronic device antennas need to transmit signals more effectively towards the signal source; therefore, positioning antennas place higher demands on their directivity.

[0003] This disclosure provides an electronic device that at least partially solves the problems in the related art.

[0004] According to a first aspect of the present disclosure, an electronic device is provided, comprising: a mid-frame assembly including a mid-plate and a frame surrounding the mid-plate, the frame including a top frame and a side frame disposed adjacent to each other; a positioning antenna, at least a portion of which is disposed on the top frame near the side frame; a circuit board mounted on the mid-plate; and an electrical resonator assembly disposed on a side surface of the circuit board facing the positioning antenna; wherein, when the positioning antenna is in operation, the electrical resonator assembly is energized to absorb energy radiated by the positioning antenna toward the electrical resonator assembly.

[0007] In some possible implementations, the positioning antenna has an open end, the feed point is located between the open end and the grounding point; one end of the electric resonator assembly extends to the side surface at a position corresponding to the open end, and the other end of the electric resonator assembly extends to the side surface at a position corresponding to the grounding point.

[0008] In some possible implementations, the distance between the electric resonator assembly and the positioning antenna ranges from 2 to 3 mm.

[0009] In some possible implementations, the electric resonator assembly includes a plurality of electric resonators spaced apart.

[0010] In some possible implementations, the electrical resonator includes a central metal strip, a first U-shaped metal strip, and a second U-shaped metal strip; the first U-shaped metal strip and the second U-shaped metal strip are disposed opposite to each other, and the opening direction of the first U-shaped metal strip is opposite to the opening direction of the second U-shaped metal strip; the central metal strip is connected between the first U-shaped metal strip and the second U-shaped metal strip, one end of the central metal strip is connected to the middle portion of the first U-shaped metal strip, and the other end of the central metal strip is connected to the middle portion of the second U-shaped metal strip.

[0015] At least a portion of the positioning antenna of the electronic device is located on the top bezel near the side bezel, and an electric resonator assembly is disposed on the side surface of the circuit board facing the positioning antenna. When the positioning antenna is working, the electric resonator assembly is excited and works in coordination to absorb the energy radiated by the positioning antenna toward the electric resonator assembly, suppressing the energy diffusion of the positioning antenna into the device and the surrounding non-communication directions, making the signal energy more concentrated in the target radiation direction (i.e., perpendicular to the device screen and facing the sky), optimizing the antenna beam directivity of the positioning antenna, and improving the positioning accuracy of the positioning antenna.

[0026] Exemplary embodiments of this disclosure will be described in detail herein, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings denote the same or similar elements unless otherwise indicated. Various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will become apparent upon understanding this disclosure.

Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0027] The embodiments described below, which are examples of some of the embodiments of this disclosure, do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0028] The specific implementation methods of the embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0029] Figure 1 This is a schematic diagram illustrating the structure of an electronic device according to an exemplary embodiment of the present disclosure. For example, the electronic device may be a tablet computer, mobile phone, e-reader, MP3 player, MP4 player, laptop computer, in-vehicle infotainment system or desktop computer, portable terminal, laptop terminal, desktop terminal, action camera, drone, monitor camera, or similar product.

[0030] like Figure 1 As shown, the electronic device includes a display screen 100, a mid-frame assembly 200, a back cover, and a circuit board. Figure 1 (Not shown in the image).

[0031] The mid-frame assembly 200, as an important structural component of the electronic device, may include a mid-plate and a frame surrounding the mid-plate. The mid-plate of the mid-frame assembly 200 can serve as a ground plane for the electronic device, providing electromagnetic shielding or a reference potential for circuit boards, antennas, etc., and reducing signal interference. The frame of the mid-frame assembly 200 can be a frame structure with through holes. The frame of the mid-frame assembly 200 can be a non-metallic frame or a metal frame such as aluminum alloy or magnesium alloy. For example, the frame of the mid-frame assembly 200 can be a rounded rectangular frame.

[0032] The display screen 100, the middle plate of the mid-frame assembly 200, and the back cover are stacked sequentially. Reception spaces are formed between the display screen 100 and the middle plate of the mid-frame assembly 200, and between the middle plate of the mid-frame assembly 200 and the back cover, to accommodate circuit boards, camera modules, batteries, various sensors, and other devices. One side of the frame of the mid-frame assembly 200 surrounds the edge of the display screen 100, and the other side surrounds the edge of the back cover, forming a complete external structure for the electronic device.

[0033] The back cover is used to form the external outline of an electronic device. During the molding process of the back cover, structures such as rear camera holes, fingerprint recognition modules, and antenna assembly mounting holes can be formed on the back cover. For example, the back cover can be a metal back cover or a non-metallic back cover, such as a plastic back cover or a glass back cover.

[0034] The circuit board can be housed in the receiving space formed by the frame and the back cover of the mid-frame assembly 200. The circuit board can be a printed circuit board (PCB) or a flexible printed circuit (FPC). Radio frequency (RF) circuitry for processing RF signals can be integrated onto the circuit board, as can controllers for controlling the operation of electronic devices.

[0035] Figure 2 This is a schematic diagram of a partial structure of an electronic device according to an exemplary embodiment of the present disclosure. Figure 2 As shown, the electronic device may include a mid-frame assembly 200, a positioning antenna 300, a circuit board 400, and a resonator assembly 500.

[0036] like Figure 2 As shown, the middle frame assembly 200 includes a middle plate 210 and a frame surrounding the middle plate 210. The frame includes a top frame 220 and a side frame 230 that are arranged adjacent to each other. In this embodiment of the present disclosure, the top frame 220 and the side frame 230 are arranged adjacent to each other and are angled together. The connection between the two can be designed with a rounded transition.

[0037] The positioning antenna 300 can be understood as an antenna specifically designed for receiving or transmitting positioning signals. It can be applied to satellite navigation, indoor positioning, or cellular network positioning, and can capture wireless signals in specific frequency bands to support the location calculation of electronic devices. In this embodiment, the positioning antenna 300 can be a GPS antenna.

[0038] At least a portion of the positioning antenna 300 is disposed on the top frame 220 near the side frame 230. In one possible embodiment, the side frame 230 is the left side frame of the frame, and the positioning antenna 300 is disposed on the top frame 220 near the side frame 230, that is, the positioning antenna 300 is disposed at the upper left corner of the electronic device.

[0039] The upper left corner of electronic devices is typically more open and less susceptible to interference from components such as camera modules, earpieces, and sensors, which helps improve the efficiency of antenna signal transmission and reception. Furthermore, the upper left corner, located at the intersection of the top and side edges, leverages the structural boundary to guide the direction of electromagnetic wave propagation, enhancing the directional concentration of antenna radiation energy. From a user perspective, when using handheld electronic devices, the upper left corner is more likely to face the sky, facilitating the establishment of stable communication links with satellite systems such as GPS and BeiDou, and improving reception sensitivity. Therefore, placing the positioning antenna 300 in the upper left corner helps achieve higher accuracy and more stable positioning functionality.

[0040] like Figure 2As shown, circuit board 400 is mounted on middle plate 210, and electric resonator assembly 500 is disposed on the side surface 410 of circuit board 400 facing the positioning antenna 300. When the positioning antenna 300 is working, the electric resonator assembly 500 is excited to work and absorbs the energy radiated by the positioning antenna 300 toward the electric resonator assembly 500.

[0041] When the positioning antenna 300 is operational, it radiates electromagnetic wave energy into the surrounding space. By mounting the electric resonator assembly 500 on the side surface 410 of the circuit board 400 facing the positioning antenna 300, it can be excited when the positioning antenna 300 is operational, thereby selectively absorbing the energy radiated from the positioning antenna 300 in that direction. By absorbing this energy, the energy diffusion of the positioning antenna 300 into the device's interior and surrounding non-communication directions can be effectively suppressed, concentrating and guiding more signal energy to the space above the device (i.e., perpendicular to the device screen and towards the sky).

[0042] In the electronic device of this disclosure, at least a portion of the positioning antenna 300 is disposed on the top frame 220 near the side frame 230, and an electric resonator assembly 500 is disposed on the side surface 410 of the circuit board 400 facing the positioning antenna 300. When the positioning antenna 300 is working, the electric resonator assembly 500 is excited and coordinated to absorb the energy radiated by the positioning antenna 300 toward the direction of the electric resonator assembly 500, suppressing the energy diffusion of the positioning antenna 300 into the device interior and surrounding non-communication directions, making the signal energy more concentrated toward the target radiation direction (i.e., perpendicular to the device screen and facing the sky), optimizing the antenna beam directivity of the positioning antenna 300, and improving the positioning accuracy of the positioning antenna 300.

[0043] In some embodiments of this disclosure, the distance between the electric resonator assembly 500 and the positioning antenna 300 ranges from 2 to 3 mm.

[0044] If the distance between the electric resonator assembly 500 and the positioning antenna 300 is too large, the electric resonator assembly 500 may not be able to effectively absorb the energy radiated by the positioning antenna 300; if the distance between the electric resonator assembly 500 and the positioning antenna 300 is too small, they may interfere with each other. Therefore, the distance between the electric resonator assembly 500 and the positioning antenna 300 is set within the range of 2 to 3 mm, allowing the electric resonator assembly 500 to electromagnetically couple with the positioning antenna 300 while also preventing mutual interference.

[0045] The electronic device of this disclosure can more effectively absorb and re-radiate the energy emitted by the positioning antenna 300 in that direction by controlling the distance between the electric resonator assembly 500 and the positioning antenna 300 to be within the range of 2 to 3 mm, and can also avoid mutual interference between the electric resonator assembly 500 and the positioning antenna 300.

[0046] Figure 3 This is a schematic diagram illustrating the structure of a positioning antenna according to an exemplary embodiment of this disclosure. Figure 3 As shown, the positioning antenna 300 includes a feed point 310. The feed point 310 is located on the top frame 220 and is used to receive feed signals to excite the positioning antenna 300 to generate electromagnetic radiation.

[0047] Feed point 310 is the interface between the positioning antenna 300 and the radio frequency signal source. It is responsible for receiving the feed signal from the circuit board 400. This feed signal excites the positioning antenna 300 to generate electromagnetic radiation to achieve the positioning function. The feed point 310 is located on the top frame 220. Specifically, it means that a feed connection position for receiving the feed signal is set on the radiating structure of the positioning antenna 300 located on the top frame 220.

[0048] In this embodiment of the electronic device, the power supply point 310 is located on the top bezel 220, which guides the electromagnetic waves generated by the positioning antenna 300 to propagate towards the upper space outside the device (i.e., perpendicular to the device screen and towards the sky). In usage scenarios, when a user holds the electronic device, the top bezel 220 is usually facing the sky. Placing the power supply point 310 on the top bezel 220 conforms to the user's usage habits, enhances the communication quality with satellite signals, and thus improves the accuracy and stability of positioning.

[0049] In some embodiments of this disclosure, such as Figure 3 As shown, the frame is made of a conductive metal material. The top frame 220 has a first slit L1, and the side frame 230 has a second slit L2. The positioning antenna 300 is formed by the frame between the first slit L1 and the second slit L2.

[0050] The frame can be made of a conductive metal material, i.e., the frame is a metal frame. By setting a first slit L1 and a second slit L2 on the top frame 220 and the side frame 230 of the metal frame, the frame portion located between the two forms the positioning antenna 300.

[0051] The electronic device of this disclosure can maintain the integrity and strength of the metal frame and save internal space by providing gaps on the top frame 220 and side frame 230 of the metal frame and forming the positioning antenna 300 through a partial frame structure.

[0052] It should be noted that this application Figure 2 and Figure 3 In the illustrated embodiments, the positioning antennas 300 are all antennas formed using a metal frame. In other embodiments of this disclosure, the frame may be made of a non-metallic material, and the positioning antenna 300 may be an FPC antenna located on the inner side of the frame.

[0053] In some embodiments of this disclosure, such as Figure 3 As shown, the positioning antenna 300 also includes a grounding point 320. The grounding point 320 is located at the corner where the top frame 220 and the side frame 230 meet, or the grounding point 320 is located on the side frame 230.

[0054] Grounding point 320 is the physical contact point where the positioning antenna 300 directly connects to the ground plane of the electronic device, providing a return path for the antenna current. In one possible implementation, grounding point 320 can be a grounding spring connected to the middle plate 210 of the middle frame assembly 200.

[0055] The grounding point 320 can be located at the corner where the top frame 220 and the side frame 230 meet, or it can be located directly on the side frame 230. This flexible arrangement provides multiple implementation methods for antenna design, which can be configured according to the specific electronic device structure, signal transmission path and electromagnetic performance requirements, ensuring the performance of the positioning antenna 300 and the integration of electronic devices.

[0056] In some embodiments of this disclosure, such as Figure 3 As shown, the positioning antenna 300 has an open end 330, and a feed point 310 is located between the open end 330 and the ground point 320. One end 510 of the electric resonator assembly 500 extends to the side surface 410 at a position corresponding to the open end 330, and the other end 520 of the electric resonator assembly 500 extends to the side surface 410 at a position corresponding to the ground point 320.

[0057] In this embodiment of the present disclosure, the positioning antenna 300 has an open end 330, and the feed point 310 is located between the open end 330 and the ground point 320, that is, the open end 330 is located on the top frame 220.

[0058] An electric resonator assembly 500 is disposed on the side surface 410 of the circuit board 400 facing the positioning antenna 300. One end 510 of the electric resonator assembly 500 extends to the position corresponding to the opening end 330 on the side surface 410, and the other end 520 of the electric resonator assembly 500 extends to the position corresponding to the grounding point 320 on the side surface 410. That is, the electric resonator assembly 500 and the radiating structure portion of the positioning antenna 300 from the opening end 330 to the grounding point 320 are correspondingly arranged.

[0059] The electronic device of this disclosure, by placing the feed point 310 between the opening end 330 and the ground point 320, and making the two ends of the electric resonator assembly 500 correspond to these two positions respectively, so that the electric resonator assembly 500 is aligned with the main current path of the positioning antenna 300 (i.e., from the opening end 330 to the ground point 320), helps the electric resonator assembly 500 to more effectively absorb the energy radiated by the positioning antenna 300 toward the electric resonator assembly 500.

[0060] In some embodiments of this disclosure, the electric resonator assembly 500 includes a plurality of electric resonators 510, which are spaced apart.

[0061] The electric resonator assembly 500 comprises a plurality of electric resonators 510, which may be ELC (Electric-LC) resonators. The plurality of electric resonators 510 are arranged at intervals along the side surface 410 of the circuit board 400. In one possible embodiment, the spacing between two adjacent electric resonators 510 is greater than 0.5 mm.

[0062] The coordinated operation of multiple electric resonators 510 can enhance the absorption of energy radiated from the positioning antenna 300. However, an excessive number of electric resonators may lead to increased coupling effects between them, affecting overall performance. Therefore, a balance needs to be struck between the number of electric resonators 510 and the coupling strength to ensure that the energy radiated from the positioning antenna 300 toward the electric resonator assembly 500 is effectively absorbed without interfering with the operation of the positioning antenna 300, and to avoid undesirable coupling effects between the electric resonators.

[0063] The electronic device of this disclosure includes an electrical resonator assembly 500 comprising a plurality of spaced resonators 510, which can effectively absorb the energy radiated by the positioning antenna 300 toward the electrical resonator assembly 500. The plurality of electrical resonators 510 are spaced apart along the side surface 410 of the circuit board 400. This spaced arrangement helps to optimize the distribution and propagation path of electromagnetic waves and avoid mutual interference from the poor coupling effects between the electrical resonators.

[0064] Figure 4 This is a schematic diagram illustrating the structure of an electric resonator according to an exemplary embodiment of this disclosure. Figure 4 As shown, the electric resonator 510 may include: a central metal strip 511, a first U-shaped metal strip 512, and a second U-shaped metal strip 513.

[0065] The first U-shaped metal strip 512 and the second U-shaped metal strip 513 are arranged opposite to each other, and the opening direction of the first U-shaped metal strip 512 and the opening direction of the second U-shaped metal strip 513 are opposite to each other.

[0066] The central metal strip 511 is connected between the first U-shaped metal strip 512 and the second U-shaped metal strip 513. One end of the central metal strip 511 is connected to the middle part of the first U-shaped metal strip 512, and the other end of the central metal strip 511 is connected to the middle part of the second U-shaped metal strip 513.

[0067] The electric resonator 510 is a resonant element used in radio frequency and microwave circuits, which generates a resonant effect at a specific frequency. The electric resonator 510 consists of an intermediate metal strip 511 connecting two U-shaped metal strips 512 and 513. The first U-shaped metal strip 512 and the second U-shaped metal strip 513 are arranged opposite each other, with their opening directions opposite to each other, forming a symmetrical structure.

[0068] When electromagnetic waves are incident on this structure, a ring current is induced between the two U-shaped metal strips, forming an equivalent LC resonant circuit, such as... Figure 5 As shown. The size of the inductor L is determined by the length and width of the central metal strip 511, and the size of the capacitor C is determined by the gap between the two U-shaped metal strips. This structure will resonate at a specific frequency, and the expression for the resonant frequency is: At the resonant frequency, the structure exhibits a strong response to external electromagnetic fields and can effectively absorb incident electromagnetic energy, thereby achieving energy regulation of the radiation direction of the positioning antenna 300.

[0069] In some embodiments of this disclosure, the gap between the first end of the first U-shaped metal strip 512 and the first end of the second U-shaped metal strip 513 is in the range of 0.1 to 0.3 mm, and / or the gap between the second end of the first U-shaped metal strip 512 and the second end of the second U-shaped metal strip 513 is in the range of 0.1 to 0.3 mm.

[0070] In some embodiments of this disclosure, the length of the central metal strip 511 ranges from 0.4 to 0.6 mm, and the width of the central metal strip 511 ranges from 0.2 to 0.4 mm.

[0071] In this embodiment of the disclosure, the electric resonator 510 can be equivalent to an LC resonant circuit. The size of the inductor L is related to the length and width of the central metal strip 511. The length of the central metal strip 511 ranges from 0.4 to 0.6 mm, and the width ranges from 0.2 to 0.4 mm. The size of the capacitor C is related to the gap between the two U-shaped metal strips. The gap ranges from 0.1 to 0.3 mm.

[0072] In the electronic device of this embodiment, the central metal strip 511 is connected between the first U-shaped metal strip 512 and the second U-shaped metal strip 513. The two U-shaped metal strips are symmetrically arranged, which can efficiently excite the ring current and form an equivalent LC resonant circuit. By designing the length of the central metal strip 511 to be in the range of 0.4 to 0.6 mm and the width to be in the range of 0.2 to 0.4 mm, the equivalent inductance L can be adjusted. In conjunction with the 0.1 to 0.3 mm gap between the two U-shaped metal strips, the equivalent capacitance C can be adjusted, so that resonance is generated at a specific frequency. This precise parameter control ensures frequency selectivity, improves signal absorption efficiency, and thus improves the overall performance and positioning accuracy of the positioning antenna 300.

[0073] Figure 6 This is a schematic diagram of the radiation direction of the positioning antenna of an electronic device in related technologies. Figure 7 This is a schematic diagram of the radiation direction of a positioning antenna for an electronic device according to an exemplary embodiment of the present disclosure. The antenna radiation pattern is presented in polar coordinates, with the center being the top edge of the electronic device, the radius representing the radiation intensity or gain, and Theta and Phi being two angular parameters in spherical coordinates, where Theta is the elevation angle (angle with the horizontal plane) and Phi is the azimuth angle (angle within the horizontal plane).

[0074] Figure 6 The radiation pattern of the localization antenna is shown in the related technology without the loading of the electric resonator assembly. Figure 7 The radiation pattern of the positioning antenna with an electric resonator assembly loaded in an embodiment of this disclosure is shown. (Comparison) Figure 6 and Figure 7 As can be seen, in the directions of Phi = 90° and Theta = 90°, the radiation gain without the electric resonator component is only -6dB, while the radiation gain with the electric resonator component is -4.5dB. This indicates that the electric resonator component effectively improves the radiation characteristics at the top of the positioning antenna, thereby enhancing antenna performance and positioning accuracy.

[0075] In the electronic device of this disclosure, at least a portion of the positioning antenna 300 is disposed on the top frame 220 near the side frame 230, and an electric resonator assembly 500 is disposed on the side surface 410 of the circuit board 400 facing the positioning antenna 300. When the positioning antenna 300 is working, the electric resonator assembly 500 is excited and coordinated to absorb the energy radiated by the positioning antenna 300 toward the direction of the electric resonator assembly 500, suppressing the energy diffusion of the positioning antenna 300 into the device interior and surrounding non-communication directions, making the signal energy more concentrated toward the target radiation direction (i.e., perpendicular to the device screen and facing the sky), optimizing the antenna beam directivity of the positioning antenna 300, and improving the positioning accuracy of the positioning antenna 300.

[0076] It should be noted that the electronic device in this embodiment can be a foldable electronic device or a flat-screen electronic device (non-foldable electronic device). Of course, in practical applications, the position of the antenna assembly can be flexibly adjusted according to factors such as the specific shape, size, internal structure, and antenna performance requirements of the electronic device, and this embodiment does not limit this.

[0077] Figure 8 This is a block diagram illustrating an electronic device according to an exemplary embodiment of the present disclosure. (Refer to...) Figure 8 The electronic device 800 may also include one or more of the following components: a processing component 802, a memory 804, a power supply component 806, a multimedia component 808, an audio component 810, an input / output (I / O) interface 812, a sensor component 814, and a communication component 816.

[0078] Processing component 802 typically controls the overall operation of electronic device 800, such as operations associated with display, telephone calls, data communication, camera operation, and recording operations. Processing component 802 may include one or more processors 820 to execute instructions to complete all or part of the steps of the methods described above. Furthermore, processing component 802 may include one or more modules to facilitate interaction between processing component 802 and other components. For example, processing component 802 may include a multimedia module to facilitate interaction between multimedia component 808 and processing component 802.

[0079] Memory 804 is configured to store various types of data to support the operation of device 800. Examples of this data include instructions for any application or method operating on electronic device 800, contact data, phonebook data, messages, pictures, videos, etc. Memory 804 can be implemented by any type of volatile or non-volatile storage device or a combination thereof, such as static random access memory (SRAM), electrically erasable programmable read-only memory (EEPROM), erasable programmable read-only memory (EPROM), programmable read-only memory (PROM), read-only memory (ROM), magnetic storage, flash memory, magnetic disk, or optical disk.

In some embodiments, the screen may include a liquid crystal display (LCD) and a touch panel (TP). If the screen includes a touch panel, the screen may 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.
