[0033] The embodiments of this disclosure will now be described with reference to the accompanying drawings. Various details of the embodiments of this disclosure are included to aid understanding and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0034] It should also be noted that the directional terms mentioned in the embodiments, such as "up," "down," "front," "back," "left," and "right," are only for reference to the directions in the accompanying drawings and are not intended to limit the scope of protection of this disclosure. Throughout the drawings, the same elements are represented by the same or similar reference numerals. Conventional structures or constructions will be omitted where they may cause confusion in understanding this disclosure.

[0035] In the technical solutions disclosed herein, the collection, storage, use, processing, transmission, provision, disclosure, and application of data (including but not limited to user personal information) comply with the provisions of relevant laws and regulations, necessary confidentiality measures have been taken, and they do not violate public order and good morals.

[0036] Before providing a further detailed description of the embodiments disclosed herein, the nouns and terms involved in the embodiments of this disclosure will be explained, and the nouns and terms involved in the embodiments of this disclosure shall be interpreted as follows.

[0037] Figure 1 This is a schematic diagram illustrating an application scenario of an electronic device according to an embodiment of this disclosure. It should be noted that... Figure 1 The examples shown are merely examples of application scenarios that can be applied to the embodiments of this disclosure, in order to help those skilled in the art understand the technical content of this disclosure, but do not mean that the embodiments of this disclosure cannot be used in other devices, systems, environments or scenarios.

[0038] like Figure 1 As shown, the application scenario 100 according to this embodiment may include electronic device 101, entity 102, 103 and 104.

[0039] A user can use electronic device 101 to send a positioning signal in the target direction. Upon contact with entities 102, 103, and 104, the positioning signal generates reflected signals from those entities. After receiving the reflected signals, electronic device 101 can identify entities 102, 103, and 104 based on the information in the reflected signals. Electronic device 101 can be various electronic devices with a display screen and web browsing support, including but not limited to smartphones, tablets, laptops, and desktop computers. Entities 102, 103, and 104 can be objects or entities.

[0040] The user can use electronic device 101 to send a positioning signal in the target direction. After receiving reflected signals from entities 102, 103, and 104 in the target direction, the user can determine the position of entities 102, 103, and 104 relative to electronic device 102 based on the reflected signals. If at least one of entities 102, 103, and 104 is a positioning device in the area, the user can determine the positioning of electronic device 102 in the area based on the relative position of electronic device 102 with at least one of entities 102, 103, and 104.

[0041] According to one embodiment of this disclosure, the electronic device includes a body and N metal rings, where N is an integer greater than or equal to 2.

[0042] N metal rings are located on the outer surface of the main body. Each of the N metal rings includes a feed point and a ground point. Each of the N metal rings serves as an antenna, and the N metal rings have the same shape. The shape of the N metal rings can be any closed shape, such as a circular ring, a rectangular ring, a rounded rectangular ring, or a triangular ring. It is understood that the shapes of the metal rings described above are for illustrative purposes only, and this disclosure does not limit the shape of the N metal rings.

[0043] The feed point of each of the N metal rings is used to receive the signal from the main body and send the signal to the target direction, or to receive the reflected signal from the target direction and transmit the reflected signal to the main body. The ground point of each metal ring is used to provide a current return path for the signal, forming a loop.

[0044] The reference ring can be of the same shape as the N metal rings and can be used to represent a virtual reference ring image of the N metal rings. The reference ring can serve as a spatial reference frame for the N metal rings, representing the position of the feed point and ground point of each of the N metal rings within the metal ring.

[0045] The feed point and ground point of each of the N metal rings are located at a first position and a second position relative to the reference ring. The first position of each metal ring relative to the reference ring indicates the position of the feed point within each metal ring. The second position of each metal ring relative to the reference ring indicates the position of the ground point within each metal ring.

[0046] You can set any one of the N metal rings as the first metal ring, and determine the metal ring that is closest to the first metal ring among the N metal rings as the second metal ring, and so on, until the Nth metal ring is determined.

[0047] Alternatively, N metal rings can be set on the outer surface of the body according to a preset trajectory. The metal ring initially set in the preset trajectory can be used as the first metal ring, and the metal ring finally set in the trajectory can be used as the Nth metal ring.

[0048] The position of the Mth metal ring in the first position of the reference ring belongs to the position of the (M-1)th metal ring on the line segment from the first position to the second position of the reference ring, excluding the first position. M is an integer greater than or equal to 2 and less than or equal to N.

[0049] It is understood that the embodiments of this disclosure reduce the interference of the electronic device structure on the antenna electromagnetic field by setting N metal rings located on the outer surface of the electronic device body as N antennas of the electronic device, thereby improving the radiation efficiency and gain of the antenna and improving the performance of communication and / or positioning.

[0050] Furthermore, by using each of the N metal rings as an antenna, the electronic device has an antenna array composed of N antennas, which can enhance the signal transmission and reception performance of the electronic device. Moreover, the antenna array can realize flexible signal transmission and reception methods, enabling the electronic device to use the antenna array composed of N metal rings to realize a variety of flexible signal-based applications by transmitting and receiving signals.

[0051] Furthermore, by arranging N metal rings that can serve as antennas on the outer surface of the electronic device body, the embodiments of this disclosure can save space inside the electronic device body, so as to reserve more space inside the body for the arrangement of other components of the electronic device.

[0052] Furthermore, by using N metal rings located on the surface of the electronic device as antennas for locating the electronic device or entities around it, the difficulty of deploying antennas for transmitting positioning signals in the electronic device is reduced.

[0053] N metal rings of the same shape can all have the same size, or all of them can be different. Alternatively, some of the metal rings can have the same size, while others can have different sizes.

[0054] Figure 2 A first schematic diagram of N metal rings according to an embodiment of the present disclosure is shown.

[0055] If all N metal rings are the same size, then the first position of the Mth metal ring on the reference ring can coincide with the second position of the (M-1)th metal ring on the reference ring; the feed point and ground point of each of the N metal rings, relative to the first and second positions of the reference ring, divide the reference ring into N equal parts.

[0056] In one example, such as Figure 2 As shown, Figure 2 It includes four circular metal rings 201, 202, 203 and 204 of the same size, with the center points of the four metal rings distributed in the order of O1, O2, O3 and O4. The center point of the first metal ring is O1, the first position of the power supply point is F1, the second position of the grounding point is G1, and the angle between the power supply point, the center of the metal ring, and the grounding point of the first metal ring is θ1. The center point of the second metal ring is O2, the first position of the power supply point is F2, the second position of the grounding point is G2, and the angle between the power supply point, the center of the metal ring, and the grounding point of the second metal ring is θ2. The center point of the third metal ring is O3, the first position of the power supply point is F3, the second position of the grounding point is G3, and the angle between the power supply point, the center of the metal ring, and the grounding point of the third metal ring is θ3. The center point of the fourth metal ring is O4, the first position of the power supply point is F4, the second position of the grounding point is G4, and the angle between the power supply point, the center of the metal ring, and the grounding point of the fourth metal ring is θ4. The feed points and grounding points of metal rings 201, 202, 203, and 204, at their first and second positions relative to the reference ring, divide the reference ring into four equal parts. Furthermore, the first position of the feed point of each metal ring 201, 202, 203, and 204 relative to the reference ring coincides with the second position of the grounding point of the adjacent metal ring relative to the reference ring. θ1=θ2=θ3=θ4=90°.

[0057] By setting a first position representing the feed point of N metal rings and a second position representing the ground point in the reference ring, the reference ring is divided equally. This ensures that the minimum signal strength of the signal sent by each of the N metal rings into space is in a different direction in space, allowing the signals sent by the N metal rings to complement each other and improving the effectiveness of the electronic device in detecting surrounding entities.

[0058] If there are metal rings of different sizes among the N metal rings, the first position of a metal ring in the reference ring can be set to not coincide with the second position of an adjacent metal ring of different sizes in the reference ring.

[0059] For example, if the size of the Mth metal ring is different from the size of the (M-1)th metal ring, the line segment of the Mth metal ring from the first position to the second position on the reference ring can partially coincide with the line segment of the (M-1)th metal ring from the first position to the second position on the reference ring.

[0060] If two adjacent metal rings have different sizes, the metal segments used for transmitting and receiving signals of two adjacent metal rings with different sizes can be set to overlap in the corresponding line segment of the reference ring. This ensures that when there are metal rings with different sizes among the N metal rings, metal rings of different sizes are used as antennas to transmit signals in the direction of the target.

[0061] For example, the reference ring can be divided into N parts by setting the grounding point of each of the N metal rings relative to the second position of the reference ring. If the size of the Mth metal ring is larger than that of the (M-1)th metal ring, then the angle between the feed point of the (M-1)th metal ring, the center of the metal ring, and the grounding point can be greater than the angle between the feed point of the Mth metal ring, the center of the metal ring, and the grounding point, so that the line segment of the Mth metal ring from the first position to the second position of the reference ring can partially coincide with the line segment of the (M-1)th metal ring from the first position to the second position of the reference ring.

[0062] By setting the angle between the feed point of the (M-1)th metal ring, the center of the metal ring, and the grounding point to be greater than the angle between the feed point of the Mth metal ring, the length of the metal segment used for signal transmission between the feed point and the grounding point of the (M-1)th metal ring and the length of the metal segment used for signal transmission between the feed point and the grounding point of the Mth metal ring are within the allowable error range. This enables the electronic device to transmit signals with frequencies within the allowable error range through metal rings of different sizes.

[0063] Furthermore, if there are N metal rings of different sizes, and some adjacent metal rings are of the same size, the positions of the feed points and grounding points of the adjacent metal rings of the same size can be determined according to the setting method of the feed points and grounding points of the adjacent metal rings of the same shape and size.

[0064] For example, if N metal rings have the same shape but different sizes, and the size of the Mth metal ring is the same as that of the (M-1)th metal ring, the first position of the Mth metal ring on the reference ring coincides with the second position of the (M-1)th metal ring on the reference ring.

[0065] Figure 3 A second schematic diagram of N metal rings according to an embodiment of the present disclosure is shown.

[0066] In one example, such as Figure 3 As shown, Figure 3It includes four circular metal rings of different sizes, 301, 302, 303 and 304, with the center points of the four metal rings distributed in the order of O5, O6, O7 and O8. The center point of the first metal ring is O5, the first position of the power supply point is F5, the second position of the grounding point is G5, and the angle between the power supply point, the center of the metal ring, and the grounding point of the first metal ring is θ5. The center point of the second metal ring is O6, the first position of the power supply point is F6, the second position of the grounding point is G6, and the angle between the power supply point, the center of the metal ring, and the grounding point of the second metal ring is θ6. The center point of the third metal ring is O7, the first position of the power supply point is F7, the second position of the grounding point is G7, and the angle between the power supply point, the center of the metal ring, and the grounding point of the third metal ring is θ7. The center point of the fourth metal ring is O8, the first position of the power supply point is F8, the second position of the grounding point is G8, and the angle between the power supply point, the center of the metal ring, and the grounding point of the fourth metal ring is θ8.

[0067] exist Figure 3 In this configuration, metal rings 301 and 304 are of the same size, and metal rings 302 and 303 are of the same size. The sizes of metal rings 301 and 304 are larger than those of metal rings 302 and 303. The metal segment of each metal ring used for transmitting and receiving electromagnetic wave signals is the longer of the two segments divided by the feed point and the ground point. Angles θ1 and θ4 can be larger than angles θ2 and θ3, ensuring that the lengths of the metal segments of metal rings 301 and 304 used for transmitting and receiving electromagnetic wave signals are within the allowable error range, and that the frequencies of the electromagnetic wave signals transmitted by metal rings 301, 302, 303, and 304 are within the error range.

[0068] According to embodiments of this disclosure, each of the N metal rings is of the same antenna type, functioning as an antenna. The N metal rings can form an antenna array, and the device can generate a composite beam signal through the N metal rings. To ensure effective generation of the composite beam, the distance between the center points of any two metal rings can be set to be less than or equal to half the wavelength of the electromagnetic wave in the antenna's operating frequency band. This ensures that the beam transmitted by the device through the N metal rings can be electromagnetically coupled to generate a composite beam signal.

[0069] The center points of any two metal rings can be set. and Spacing between ,in, It can be determined using the speed of light and the operating frequency of electromagnetic waves, as shown in the following formula:

[0070]

[0071] in, Let f be the speed of light, and f be the frequency of the electromagnetic wave signal transmitted by each metal ring as an antenna.

[0072] In one example, continuing with the above... Figure 2 The examples illustrate this point: the distances between O1 and O2, O2 and O3, O3 and O4, and O4 and O1 are all less than half the wavelength of the electromagnetic waves in the antenna's operating frequency band.

[0073] In another example, continuing with the above... Figure 3 The examples illustrate this point: the distances between O5 and O6, O6 and O7, O7 and O8, and O8 and O5 are all less than half the wavelength of the electromagnetic waves in the antenna's operating frequency band.

[0074] Each of the N metal rings can be divided into two metal segments by a feed point and a ground point. Each metal ring can be configured as a dual-band antenna, with the two metal segments of each ring used to transmit electromagnetic wave signals of different operating frequencies.

[0075] According to embodiments of this disclosure, each of the N metal rings functions as an antenna and operates simultaneously. Each antenna concurrently transmits electromagnetic wave signals in a first operating frequency band and an electromagnetic wave signal in a second operating frequency band. The feed point and ground point of each of the N metal rings are divided into a first metal segment and a second metal segment, with the first metal segment being shorter than the second metal segment. The first metal segment is used to transmit and receive electromagnetic wave signals in the first operating frequency band, and the second metal segment is used to transmit and receive electromagnetic wave signals in the second operating frequency band. The first operating frequency band is higher than the second operating frequency band.

[0076] Each metal ring includes a first metal segment and a second metal segment, separated by a feed point and a ground point, wherein the first metal segment is shorter than the second metal segment. Taking an example where each of the N metal rings can function as an antenna for transmitting and receiving Wi-Fi signals, the first metal segment of each metal ring can be used to transmit and receive Wi-Fi signals in the 5GHz band, and the second metal segment of each metal ring can be used to transmit and receive Wi-Fi signals in the 2.4GHz band.

[0077] In one example, continuing with the above... Figure 2Using the examples below, the metal segment F1 pointing clockwise to G1 can be the first metal segment of metal ring 201, and the metal segment G1 pointing clockwise to F1 can be the second metal segment of metal ring 201. Similarly, the metal segment F2 pointing clockwise to G2 can be the first metal segment of metal ring 202, and the metal segment G2 pointing clockwise to F2 can be the second metal segment of metal ring 202. The metal segment F3 pointing clockwise to G3 can be the first metal segment of metal ring 203, and the metal segment G3 pointing clockwise to F3 can be the second metal segment of metal ring 203. Finally, the metal segment F4 pointing clockwise to G4 can be the first metal segment of metal ring 204, and the metal segment G4 pointing clockwise to F4 can be the second metal segment of metal ring 204.

[0078] In one example, continuing with the above... Figure 3 Using the examples provided, the metal segment pointing clockwise from F5 to G5 can serve as the first metal segment of metal ring 301, and the metal segment pointing clockwise from G5 to F5 can serve as the second metal segment of metal ring 301. Similarly, the metal segment pointing clockwise from F6 to G6 can serve as the first metal segment of metal ring 302, and the metal segment pointing clockwise from G6 to F6 can serve as the second metal segment of metal ring 302. Likewise, the metal segment pointing clockwise from F7 to G7 can serve as the first metal segment of metal ring 303, and the metal segment pointing clockwise from G7 to F7 can serve as the second metal segment of metal ring 303. Finally, the metal segment pointing clockwise from F8 to G8 can serve as the first metal segment of metal ring 304, and the metal segment pointing clockwise from G8 to F8 can serve as the second metal segment of metal ring 304.

[0079] It is understandable that if each of the N metal rings can be used as an antenna to transmit and receive electromagnetic wave signals in multiple operating frequency bands, then the distance between the center points of any two metal rings is less than or equal to half the wavelength of the electromagnetic wave in the antenna's maximum operating frequency band.

[0080] For example, if each of N metal rings can function as an antenna to transmit and receive 2.45GHz and 5.5GHz Wi-Fi signals, and the second metal segment of each ring is used for transmitting and receiving 2.45GHz Wi-Fi signals, and the first metal segment is used for transmitting and receiving 5.5GHz Wi-Fi signals, then the distance between the center points of any two metal rings should be less than half the wavelength of the 2.45GHz Wi-Fi signal (61.18mm), and the distance between the center points of any two metal rings should be less than half the wavelength of the 5.5GHz Wi-Fi signal (27.25mm). The maximum distance between the center points of any two metal rings can be set to 26.3mm.

[0081] An antenna array consisting of N metal rings can be a phased array antenna, where each metal ring acts as an antenna and can transmit an electromagnetic wave beam with rotational symmetry.

[0082] According to an embodiment of this application, each of the N metal rings serves as a feed point for an antenna, satisfying a rotating distribution of feed points.

[0083] In this configuration, each of the N metal rings acts as an antenna corresponding to a phase, and all of the N metal rings are simultaneously in operation as antennas to achieve a spiral phase distribution of the electromagnetic wave beam.

[0084] Each of the N metal rings acts as an antenna, corresponding to a phase value, indicating that each antenna corresponds to an initial phase value of the transmitted electromagnetic wave signal.

[0085] In the process of N metal rings, each metal ring acts as an antenna and transmits electromagnetic wave signals in parallel, the electromagnetic waves transmitted by the N antennas can be superimposed to generate a spirally propagating electromagnetic wave beam.

[0086] For example, the feed points of N metal rings are arranged in a rotating pattern, allowing an antenna array composed of N metal rings to meet the characteristics of an Orbital Angular Momentum (OAM) antenna. Each of the N metal rings can be used as an antenna, with all N antennas operating simultaneously. Each antenna transmits a Wi-Fi signal with a different initial phase value, which is then superimposed to form an OAM beam signal.

[0087] According to embodiments of this disclosure, each of the N metal rings can serve as an antenna for a wireless local area network (WLAN).

[0088] Each of the N metal rings acts as a wireless LAN antenna, enabling electronic devices to transmit and receive Wi-Fi signals for communication with external devices or networks. For example, Wi-Fi 7 supports positioning methods using Angle of Arrival (AOA) or Angle of Departure (AOD). These N metal rings can be arranged into a wireless LAN antenna array for real-time Wi-Fi positioning of electronic devices.

[0089] The N wireless LAN antennas are also used for at least one of the following: as a distance detection device for locating a target; as an angle detection device for locating a target.

[0090] Each WLAN antenna can receive the reflected signal from the OAM beam signal of the entity to be located. Each antenna can determine the distance between the entity and each antenna based on the time difference between transmitting and receiving the reflected signal. By using the distances between the N WLAN antennas and the entity to be located, the positional relationship between the entity and the electronic device can be determined. The OAM beam signal contains angular information. Each WLAN antenna can receive the reflected signal from the OAM beam signal of the entity to be located. Each antenna can determine the direction information between the entity and each antenna based on the angular information of the reflected signal. By using the direction information between the N WLAN antennas and the entity to be located, the positional relationship between the entity and the electronic device can be determined.

[0091] The following explains how Wi-Fi is located:

[0092] Wi-Fi real-time positioning is a positioning technology that uses existing wireless networks, in conjunction with Wi-Fi tags and related mobile terminal devices, such as mobile phones, tablets, and laptops with Wi-Fi signal transmission and reception capabilities, and combined with corresponding positioning algorithms to determine the location of relevant people and objects.

[0093] Wi-Fi positioning systems are based on the standard IEEE 802.11 wireless local area network (WLAN). The positioning algorithm is based on the received signal strength indicator (RSSI) of the Wi-Fi signal.

[0122] like Figure 9A As shown, the horizontal axis of the reflection coefficient curve of the electronic device represents the frequency of the electromagnetic wave emitted by the metal ring as an antenna, and the vertical axis represents the reflection coefficient of the electromagnetic wave signal emitted by the metal ring. The reflection coefficient is used to represent the signal strength that the metal ring fails to effectively emit as an antenna.

[0123] exist Figure 9A In this configuration, the N metal rings operate at frequencies including 2.45 GHz and 5.5 GHz. According to... Figure 9A It can be determined that when N metal rings are used as antennas to transmit signals, the reflection coefficient at the operating frequency can be basically lower than the industrial standard threshold of -10dB. The antennas with multiple metal rings have achieved good impedance matching in the operating frequency band, and the mutual coupling effect between ports has been effectively suppressed.

[0124] Figure 9B An isolation curve of an electronic device according to an embodiment of the present disclosure is illustrated schematically.

[0125] like Figure 9B As shown, the horizontal axis of the port isolation curve of the electronic device represents the frequency of the electromagnetic wave emitted by the metal ring as an antenna, and the vertical axis represents the transmission coefficient. The transmission coefficient is used to represent the signal strength of a signal emitted from one metal ring as an antenna and coupled to a signal emitted from another metal ring as an antenna, i.e., the isolation between antennas. Parameters S21, S31, S41, S32, S42, and S43 represent the signal coupling strength between different antenna pairs among the N antennas formed by the N metal rings of the electronic device.

Based on this figure, it can be determined that when the N metal rings operate individually as antennas, the transmission coefficient near the main operating frequency points can be essentially below the design threshold of -15 dB. This indicates that the multiple metal ring antennas achieve excellent inter-port isolation in the operating frequency band, and the mutual coupling effect between antenna elements is effectively suppressed.

[0132] like Figure 10 As shown in (A), Figure 10 (A) represents the radiation pattern of the first metal ring out of four metal rings when it emits a 5.15 GHz Wi-Fi signal. The direction of the strongest signal radiation from the first metal ring is 240°.

[0133] like Figure 10 As shown in (B), Figure 10 (B) is used to represent the radiation pattern when the second metal ring out of the four metal rings emits a 5.15 GHz Wi-Fi signal. The direction of the strongest signal radiation from the second metal ring is approximately 340°.

[0134] like Figure 10 As shown in (C), Figure 10(C) represents the radiation pattern when the third metal ring out of the four metal rings emits a 5.15 GHz Wi-Fi signal. The direction of the strongest signal radiation from the third metal ring is approximately 15°.

[0135] like Figure 10 As shown in (D), Figure 10 (D) represents the radiation pattern when the fourth metal ring out of the four metal rings emits a 5.15 GHz Wi-Fi signal. The direction of the strongest signal radiation from the fourth metal ring is approximately 80°.

[0136] according to Figure 10 (A), (B), (C), and (D) indicate that the feed points of each of the four metal rings are distributed in a rotating manner as one of the antennas. This allows the direction in which the strongest signal is radiated by each antenna to be distributed in a rotating manner, generating uniform or non-uniform OAM mode beams, which can significantly improve the accuracy and reliability of the Wi-Fi positioning system.
