Description

Electronic device including a plurality of antenna elements and method for controlling the same

[0001] Various embodiments disclosed in this document relate to an electronic device including a plurality of antenna elements and a method of controlling the same.

[0002] With the advancement of wireless communication technology, electronic devices utilizing wireless communication, including at least one antenna, have become widespread. Since the commercialization of communication systems for portable wireless communication devices, wireless communication technology in electronic devices has been utilized and developed in a variety of fields.

[0003] The electronic device can locate the source of a signal using a signal received through at least one antenna, and can use an ultra-wideband (UWB) signal having a frequency band of about 500 MHz or more.

[0004] For example, an electronic device can calculate the distance from a source to the electronic device by exchanging pulse signals in a double-sided two-way ranging (DS-TWR) manner. Alternatively, the electronic device can calculate the relative bearing of the source by referring to the phase difference of arriving signals (PDoA) of each signal arriving at two antennas.

[0005] However, the above-described content should not be construed as the applicant's recognition of the content described in this document as prior art, but should only be construed as technology (related art) related to the invention described in this document.

[0006] Electronic devices can measure the angle of arrival (AoA) using the PDoA of signals received from multiple antenna elements. However, if the spacing between the multiple antenna elements exceeds a certain range (e.g., half a wavelength of the received signal), overlapping PDoA references may occur, making it difficult to measure the AoA. Furthermore, if the spacing between the multiple antenna elements is less than a certain range, the resolution may be insufficient at certain angles, which may lower reliability, and AoA coverage may be limited.

[0007] Additionally, since the space inside an electronic device is limited, there is a limit to the spacing between multiple antenna elements, and accordingly, the arrangement of multiple antenna elements results in a lower resolution and a limited AoA coverage.

[0008] An electronic device including a plurality of antenna elements according to one embodiment of the present document and a method of controlling the same can provide reliability and accuracy of AoA measurement, improve resolution of PDoA, and / or extend the supported coverage of AoA.

[0009] The technical problems to be achieved through the various embodiments disclosed in this document are not limited to the technical problems mentioned above, and other technical problems not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the invention described in this document belongs from the description below.

[0010] An electronic device according to one embodiment may include a substrate including a first surface facing a first direction and a second surface facing a second direction opposite to the first direction, and a plurality of antenna elements connected to the substrate. In one embodiment, the plurality of antenna elements may include a first antenna element disposed on the first surface of the substrate, a second antenna element disposed on the first surface of the substrate and spaced apart from the first antenna element by a first distance based on a third direction, which is a direction orthogonal to the first direction, and a third antenna element disposed spaced apart from the first antenna element by a second distance greater than the first distance based on the third direction, and electrically isolated from the second antenna element.

[0011] In addition, a control method of an electronic device according to an embodiment may receive a first signal for a positioning signal from a first antenna element. A control method of an electronic device according to an embodiment may receive a second signal for a positioning signal from a second antenna element that is arranged to be spaced apart from the first antenna element by a first separation distance based on a predetermined separation direction. A control method of an electronic device according to an embodiment may receive a third signal for a positioning signal from a third antenna element that is arranged to be spaced apart from the first antenna element by a second separation distance greater than the first separation distance based on the separation direction and is electrically separated from the second antenna element. A control method of an electronic device according to an embodiment may identify a phase difference of arriving signal (PDoA) of at least some of the first signal, the second signal, and the third signal. A method of controlling an electronic device according to an embodiment can measure an angle of arrival (AoA) with a positioning target by using a phase difference between the identified first signal and the identified second signal and a phase difference between the identified first signal and the identified third signal.

[0012] In addition, an electronic device according to one embodiment may include a housing including a first plate facing a first direction, a second plate facing a second direction opposite to the first direction, and a side member surrounding a space between the first plate and the second plate and connecting one side of the first plate and one side of the second plate, a display visually exposed through at least a portion of the second plate, a first side facing the first direction, a substrate provided inside the housing, and a plurality of antenna elements connected to the substrate. The plurality of antenna elements may include a first antenna element, a second antenna element spaced apart from the first antenna element by a first separation distance based on a third direction, which is a direction orthogonal to the first direction, and a third antenna element spaced apart from the first antenna element by a second separation distance greater than the first separation distance based on the third direction, and electrically isolated from the second antenna element.

[0031] Hereinafter, embodiments will be described in detail with reference to the attached drawings. In the description with reference to the attached drawings, identical components are assigned the same reference numerals regardless of the drawing numbers, and redundant descriptions thereof will be omitted.

[0032] The various embodiments and terminology used herein are not intended to limit the technical features described in the present disclosure to specific embodiments, but should be understood to include various modifications, equivalents, or substitutes of the embodiments. In connection with the description of the drawings, similar reference numerals may be used for similar or related components. The singular form of a noun corresponding to an item may include one or more of the items, unless the context clearly indicates otherwise. In the present disclosure, each of the phrases "A or B," "at least one of A and B," "at least one of A or B," "A, B, or C," "at least one of A, B, and C," and "at least one of A, B, or C" can include any one of the items listed together in the corresponding phrase among the phrases, or all possible combinations thereof. Terms such as "first", "second", or "first" or "second" may be used merely to distinguish the corresponding component from other corresponding components and do not limit the corresponding components in any other respect (e.g., importance or order). When a component (e.g., a first) is referred to as "coupled" or "connected" to another component (e.g., a second) with or without the terms "functionally" or "communicatively," it means that the component can be connected to the other component directly (e.g., wired), wirelessly, or through a third component.

[0033] The term "module" used in various embodiments may include a unit implemented in hardware, software, or firmware, and may be used interchangeably with terms such as logic, logic block, component, or circuit. A module may be an integral component, or a minimum unit or part of such a component that performs one or more functions. For example, according to one embodiment, a module may be implemented in the form of an application-specific integrated circuit (ASIC).

[0034] Various embodiments may be implemented as software (e.g., a program (120)) including one or more instructions stored in a storage medium (e.g., an internal memory (136) or an external memory (138)) readable by a machine (e.g., an electronic device). For example, a processor of the machine (e.g., an electronic device) may call at least one instruction among the one or more instructions stored from the storage medium and execute it. This enables the machine to operate to perform at least one function according to the at least one called instruction. The one or more instructions may include code generated by a compiler or code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. Here, 'non-transitory' simply means that the storage medium is a tangible device and does not contain signals (e.g. electromagnetic waves), and the term does not distinguish between cases where data is stored semi-permanently or temporarily on the storage medium.

[0035] According to one embodiment, the method according to the various embodiments disclosed in the present disclosure may be provided as included in a computer program product. The computer program product may be traded as a product between a seller and a buyer. The computer program product may be distributed in the form of a machine-readable storage medium (e.g., compact disc read only memory (CD-ROM)), or may be distributed online (e.g., downloaded or uploaded) via an application store (e.g., Play Store™) or directly between two user devices (e.g., smartphones). In the case of online distribution, at least a portion of the computer program product may be temporarily stored or temporarily generated in a machine-readable storage medium, such as the memory of a manufacturer's server, an application store's server, or an intermediary server.

[0036] According to various embodiments, each component (e.g., a module or a program) of the above-described components may include one or more entities, and some of the entities may be separated and placed in other components. According to various embodiments, one or more components or operations of the aforementioned components may be omitted, or one or more other components or operations may be added. Alternatively or additionally, a plurality of components (e.g., a module or a program) may be integrated into a single component. In such a case, the integrated component may perform one or more functions of each of the plurality of components identically or similarly to those performed by the corresponding component among the plurality of components prior to the integration. According to various embodiments, the operations performed by a module, program, or other component may be executed sequentially, in parallel, iteratively, or heuristically, or one or more of the operations may be executed in a different order, omitted, or one or more other operations may be added.

The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (194) (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0060] FIG. 2 is a block diagram (200) of a wireless communication module (192), a power management module (188), and an antenna module (197) of an electronic device according to various embodiments.

[0061] Referring to FIG. 2, the wireless communication module (192) may include an MST communication module (210) or an NFC communication module (230), and the power management module (188) may include a wireless charging module (250). In this case, the antenna module (197) may include a plurality of antennas, including an MST antenna (297-1) connected to the MST communication module (210), an NFC antenna (297-3) connected to the NFC communication module (230), and a wireless charging antenna (297-5) connected to the wireless charging module (250). For convenience of explanation, components overlapping with those in FIG. 1 are omitted or briefly described.

[0062] The MST communication module (210) can receive a signal including control information or payment information such as card information from the processor (120), generate a magnetic signal corresponding to the received signal through the MST antenna (297-1), and then transmit the generated magnetic signal to an external electronic device (102) (e.g., a POS device). In order to generate the magnetic signal, according to one embodiment, the MST communication module (210) includes a switching module (not shown) including one or more switches connected to the MST antenna (297-1), and can control the switching module to change the direction of a voltage or current supplied to the MST antenna (297-1) according to the received signal. The change in the direction of the voltage or current enables the direction of the magnetic signal (e.g., a magnetic field) transmitted through the MST antenna (297-1) to change accordingly. A magnetic signal in a state of changing direction, when detected by an external electronic device (102), may cause an effect (e.g., waveform) similar to a magnetic field generated when a magnetic card corresponding to the received signal (e.g., card information) is read (swiped) by a card reader of the electronic device (102). According to one embodiment, payment-related information and control signals received in the form of the magnetic signal by the electronic device (102) may be transmitted to an external server (108) (e.g., payment server) via, for example, a second network (199).

[0063] The NFC communication module (230) can obtain a signal including control information or payment information such as card information from the processor (120) and transmit the obtained signal to an external electronic device (102) via the NFC antenna (297-3). According to one embodiment, the NFC communication module (230) can receive such a signal transmitted from an external electronic device (102) via the NFC antenna (297-3).

[0064] The wireless charging module (250) can wirelessly transmit power to an external electronic device (102) (e.g., a mobile phone or a wearable device) via a wireless charging antenna (297-5), or wirelessly receive power from an external electronic device (102) (e.g., a wireless charging device).

[0090] In one embodiment, the electronic device (301) may include a connection terminal (378) (e.g., the connection terminal (178) of FIG. 1). In one embodiment, the connection terminal (378) may be disposed on an outer surface of the housing (310), for example, may be disposed on a lower surface (311c) of the electronic device (301) as illustrated in FIG. 3A. Specifically, when the electronic device (301) is viewed in one direction (e.g., the +Y-axis direction of FIG. 3A), the connection terminal (378) may be disposed at a central portion of the lower surface (311c).

[0091] As illustrated in FIGS. 3a and 3b, the connection terminal (378) may be arranged on the side (311c) of the housing (310) forming the exterior of the electronic device (301), but in actual implementation, it is not limited thereto, and at least some of them may be arranged on the front (310a) or rear (310b) of the housing (310), or may be arranged inside the housing (310).

[0096] FIG. 4 is a diagram illustrating the positioning of an electronic device (401) according to one embodiment.

[0097] FIG. 4 is an exemplary drawing for explaining AoA positioning of an electronic device (401) according to one embodiment, and the positioning method of the electronic device (401) according to one embodiment of the present document is not limited thereto, and the electronic device (401) can use various positioning methods through a plurality of antenna elements (410, 420).

[0098] Referring to FIG. 4, an electronic device (401) according to one embodiment (e.g., electronic device (101) of FIG. 1, electronic device (301) of FIGS. 3A, 3B, and 3C) may include a plurality of elements (410, 420) (e.g., antenna module (197) of FIGS. 1 and 2).

[0099] Hereinafter, any content overlapping with the above will be omitted for explanation, and it is to be understood that, in the electronic device (401), some configurations and structures may be replaced, added, or omitted within a range easily understandable to those skilled in the art by referring to the drawings and descriptions below. In addition, at least one configuration or feature of the embodiments described above may be combined in the electronic device (401) unless it is technically clearly impossible.

[0100] In one embodiment, a positioning target (405) can transmit a positioning signal (407). The positioning target (405) can be another electronic device (e.g., electronic device (102) or electronic device (104) of FIG. 1), a signal source, or a transmitter (Transmit; Tx). The positioning target (405) can be spaced apart from the electronic device (401). The positioning signal (407) can form a waveform (408) having a specific wavelength (λ).

[0101] In one embodiment, the plurality of antenna elements (410, 420) may include a first antenna element (410) and a second antenna element (420). The first antenna element (410) and the second antenna element (420) may be arranged to be spaced apart from each other by a distance (D) based on a certain direction. The first antenna element (410) and the second antenna element (420) may each receive a first signal (413) and a second signal (423).

[0102] In one embodiment, the distance between the positioning target (405) and the electronic device (401) may be relatively large compared to the separation distance (D) of the plurality of antenna elements (410, 420) of the electronic device (401). Accordingly, it may be assumed that the received signals (413, 423) transmitted to each of the plurality of antenna elements (410, 420) are transmitted substantially horizontally to the plurality of antenna elements (410, 420).

[0103] In one embodiment, the electronic device (401) can measure an angle of arrival (AoA) with a positioning target (405) using a processor (e.g., processor (120) of FIG. 1) and a memory (e.g., memory (130) of FIG. 1).

[0104] In one embodiment, the processor (120) can receive reception signals (413, 423) from a plurality of antenna elements (410, 420). A memory (130) is operatively connected to the processor (120) and can store executable instructions. The processor (120) can measure the AoA from the electronic device (401) to the positioning target (405) by executing the instructions stored in the memory (130).

[0105] In one embodiment, due to the separation distance (D) between the first antenna element (410) and the second antenna element (420), the phase (P1) of the first signal (413) received by the first antenna element (410) and the phase (P2) of the second signal (423) received by the second antenna element (420) may be different from each other. The processor (120) may identify the phase (P1) of the first signal (413) and the phase (P2) of the second signal (423) to measure a phase difference of arriving signal (PDoA).

[0106] In one embodiment, the separation distance (D) may be stored in the memory (130) of the electronic device (401). The separation distance (D) may be a physical distance between the center of the first antenna element (410) and the center of the second antenna element (420). Alternatively, the separation distance (D) may be a physical distance between one end of the first antenna element (410) and one end of the second antenna element (420). Alternatively, the separation distance (D) may mean an electrical separation distance between a plurality of antenna elements (410, 420).

[0107] In one embodiment, when the positioning signal (407) has a frequency band in the GHz unit of an ultra-wideband (UWB) and the separation distance (D) is equal to or close to half the wavelength (λ) (e.g., λ / 2), the electronic device (401) can derive reliable AoA measurement results. For example, the separation distance (D) may be equal to half the wavelength (λ) of the positioning signal (407) (e.g., λ / 2). Alternatively, the separation distance (D) may have a length in a range that includes half the wavelength (λ) of the positioning signal (407) (e.g., λ / 2), for example, a range of + / - 3%, + / - 5%, + / - 10%, or + / - 20% of the length of half the wavelength (λ).

[0108] In one embodiment, the processor (120) may execute instructions for a positioning algorithm stored in the memory (130) (e.g., the basic positioning algorithm (A1) of FIG. 7, the correction positioning algorithm (A2) of FIG. 8, or the meta positioning algorithm (A4) of FIG. 10b) to measure AoA using a phase difference.

[0109] FIG. 5 is a rear view of an electronic device (501) including a plurality of antenna elements (530) according to one embodiment.

[0110] Referring to FIG. 5, an electronic device (501) according to one embodiment (e.g., the electronic device (101) of FIG. 1, the electronic device (301) of FIGS. 3A, 3B, and 3C, or the electronic device (401) of FIG. 4) may include a substrate (520) (e.g., the PCB assembly (351, 352) of FIG. 3C) and a plurality of antenna elements (530) (e.g., the antenna module (178) of FIGS. 1 and 2, or the plurality of antenna elements (410, 420) of FIG. 4).

[0111] Hereinafter, any content overlapping with the above will be omitted for explanation, and it is to be understood that, in the electronic device (501), some configurations and structures may be replaced, added, or omitted within a range easily understandable to those skilled in the art by referring to the drawings and descriptions below. In addition, at least one configuration or feature of the embodiments described above may be combined in the electronic device (501) unless it is technically clearly impossible.

[0112] In one embodiment, the substrate (520) may include a first surface (521) facing a first direction (e.g., a -Z direction) and a second surface (522) facing a second direction (e.g., a +Z direction) opposite to the first direction. A plurality of electrical components may be provided on the substrate (520), and the substrate (520) may be disposed inside the housing (510).

[0113] In one embodiment, a plurality of antenna elements (530) may be electrically and / or physically connected to the substrate (520). The plurality of antenna elements (530) may include a first antenna element (531), a second antenna element (532), and a third antenna element (533). The plurality of antenna elements (530) may receive signals from a positioning target (e.g., a positioning target (405) of FIG. 4).

[0114] In one embodiment, the first antenna element (531) and the second antenna element (532) may be disposed on the first surface (521) of the substrate (520). The first antenna element (531) and the second antenna element (532) may be spaced apart by a first separation distance (D1).

[0115] In one embodiment, the first separation distance (D1) may be a straight-line distance between the first antenna element (531) and the second antenna element (532) in a third direction (e.g., the -X direction) that is orthogonal to the first direction.

[0116] For example, the first direction may be a direction in which either the rear or the front of the electronic device (501) faces, the second direction may be a direction in which the other one of the rear or the front of the electronic device (501) faces, the third direction may be a direction in which either one of the multiple sides of the electronic device (501) faces, and the fourth direction opposite to the third direction may be a direction in which the other one of the multiple sides of the electronic device (501) faces.

[0117] Alternatively, for example, in an electronic device (501) having a front or back surface of a rectangular shape, the third direction and the fourth direction may be either the two directions of the short axis of the electronic device (501) (e.g., +X direction and -X direction) or the two directions of the long axis of the electronic device (501) (e.g., +Y direction and -Y direction).

[0118] However, the above description is merely an example, and the first direction, the second direction, the third direction, and the fourth direction may be variously changed in consideration of the shape, structure, and characteristics of the electronic device (501).

[0119] In one embodiment, the first separation distance (D1) may be a distance from a geometric center of the first antenna element (531) to a geometric center of the second antenna element (532). Alternatively, the first separation distance (D1) may be a distance from one end (e.g., the -X-axis end) of the first antenna element (531) to the same one end (e.g., the -X-axis end) of the second antenna element (532), or may be an electrical separation distance between the first antenna element (531) and the second antenna element (532).

[0120] In one embodiment, the third antenna element (533) may be disposed on the first side (521) of the substrate (520). The first antenna element (531) and the third antenna element (533) may be spaced apart by a second separation distance (D2). The second separation distance (D2) may be greater than the first separation distance (D1).

[0121] In one embodiment, the second antenna element (532) and the third antenna element (533) may be electrically isolated from each other. Each of the second antenna element (532) and the third antenna element (533) may independently receive signals.

[0122] In one embodiment, the first separation distance (D1) may be equal to half the wavelength (λ) of the positioning signal transmitted by the positioning target (e.g., the positioning signal (407) of FIG. 4) (e.g., λ / 2), or may be smaller than half the wavelength (λ) (e.g., λ / 2). Additionally, the second separation distance (D2) may be greater than half the wavelength (λ) of the positioning signal transmitted by the positioning target (e.g., λ / 2).

[0123] In one embodiment, the memory (130) may store a positioning algorithm based on a first separation distance (D1) and a second separation distance (D2). Alternatively, the memory (130) may store the first separation distance (D1) and the second separation distance (D2), and may also store an operation for setting a positioning algorithm using the first separation distance (D1) and the second separation distance (D2). The processor (120) may use the memory (130) to set or use the positioning algorithm.

[0124] In one embodiment of the present document, the electronic device (501) can improve the performance of measuring AoA with a positioning target through a plurality of antenna elements (530) spaced apart by a first separation distance (D1) and a second separation distance (D2).

[0125] For example, the electronic device (501) can expand the AoA measurement coverage. Alternatively, the electronic device (501) can improve the AoA measurement reliability and accuracy. The operation of the processor (120) of the electronic device (501) using the plurality of antenna elements (530) spaced apart by a first separation distance (D1) and a second separation distance (D2) according to an embodiment of the present document and the control method (600) of the electronic device (501) are described below in FIG. 7.

[0126] In one embodiment, the first antenna element (531), the second antenna element (532), and the third antenna element (533) may be arranged in a row in the third direction. Alternatively, the plurality of antenna elements (530) may be arranged on a single straight line parallel to the third direction without being spaced apart in another direction perpendicular to the first direction and the third direction (e.g., the Y-axis direction).

[0127] In one embodiment, a plurality of antenna elements (530) are arranged in a row, thereby reducing errors that may occur when at least one of them is spaced in a different direction, and improving AoA measurement reliability and accuracy.

[0128] In one embodiment of the present document, the arrangement design of the plurality of antenna elements (530) can be implemented in various ways, within a range where the plurality of antenna elements (530) are spaced apart by a first separation distance (D1) and a second separation distance (D2) along the third direction.

[0129] For example, although not shown in the drawing, at least some of the plurality of antenna elements (530) may be spaced apart in a direction perpendicular to the first direction and the third direction (e.g., the Y-axis direction). Even in this case, since each of the plurality of antenna elements (530) is spaced apart in the third direction, the AoA with the positioning target can be measured along the third direction with respect to the first direction. In addition, by being designed to be arranged in various ways within the limited space of the electronic device (501) and the substrate (520), the space efficiency of the electronic device (501) can be provided.

[0130] FIG. 6 is a rear view of an electronic device (501) including a plurality of antenna elements (530) according to one embodiment.

[0131] Referring to FIG. 6, the third antenna element (533) according to one embodiment may be formed of a conductive member of the housing (510).

[0132] Hereinafter, any content overlapping with the above will be omitted for explanation, and it is to be understood that, in the electronic device (501), some configurations and structures may be replaced, added, or omitted within a range easily understandable to those skilled in the art by referring to the drawings and descriptions below. In addition, at least one configuration or feature of the embodiments described above may be combined in the electronic device (501) unless it is technically clearly impossible.

[0133] In one embodiment, the housing (510) may include a first plate facing a first direction (e.g., a rear plate (311b) of FIGS. 3B and 3C) and a second plate facing a second direction (e.g., a front plate (311a) of FIGS. 3A and 3C). For example, FIG. 6 may be a plan view of the interior of the housing (510) of the electronic device (501) with the first plate open.

[0134] In one embodiment, the housing (510) may include a side member (e.g., side member (340) of FIGS. 3B and 3C). The side member may enclose a space between the first plate and the second plate and connect one side of the first plate and one side of the second plate. Alternatively, the side member may be a portion of the housing (510) that faces a side (e.g., a side facing the XY direction).

[0135] In one embodiment, the substrate (520) may include a first surface (521) facing a first direction (e.g., a -Z direction) and a second surface (522) facing a second direction (e.g., a +Z direction) opposite to the first direction. A plurality of electrical components may be provided on the substrate (520), and the substrate (520) may be disposed inside the housing (510).

[0136] In one embodiment, the first antenna element (531) and the second antenna element (532) may be disposed on the first surface (521) of the substrate (520). The first antenna element (531) and the second antenna element (532) may be spaced apart by a first separation distance (D1).

[0137] In one embodiment, the first separation distance (D1) may be a straight-line distance between the first antenna element (531) and the second antenna element (532) in a third direction (e.g., the -X direction) that is orthogonal to the first direction.

[0138] For example, the first direction may be a direction in which either the rear or the front of the electronic device (501) faces, the second direction may be a direction in which the other one of the rear or the front of the electronic device (501) faces, the third direction may be a direction in which either one of the multiple sides of the electronic device (501) faces, and the fourth direction opposite to the third direction may be a direction in which the other one of the multiple sides of the electronic device (501) faces.

[0139] Alternatively, for example, in an electronic device (501) having a front or back surface of a rectangular shape, the third direction and the fourth direction may be either the two directions of the short axis of the electronic device (501) (e.g., +X direction and -X direction) or the two directions of the long axis of the electronic device (501) (e.g., +Y direction and -Y direction).

[0140] However, the above description is merely an example, and the first direction, the second direction, the third direction, and the fourth direction may be variously changed in consideration of the shape, structure, and characteristics of the electronic device (501).

[0141] In one embodiment, the first separation distance (D1) may be a distance from a geometric center of the first antenna element (531) to a geometric center of the second antenna element (532). Alternatively, the first separation distance (D1) may be a distance from one end (e.g., the -X-axis end) of the first antenna element (531) to the same one end (e.g., the -X-axis end) of the second antenna element (532), or may be an electrical separation distance between the first antenna element (531) and the second antenna element (532). In one embodiment, the third antenna element (533) may be formed of a conductive member provided on the side member. The first antenna element (531) and the third antenna element (533) may be spaced apart by a second separation distance (D2). The second separation distance (D2) may be greater than the first separation distance (D1).

[0142] In one embodiment, since the internal space of the electronic device (501) and the area of ​​the first side (521) of the substrate (520) are limited, the third antenna element (533) may be disposed outside the substrate (520), for example, in the housing (510), thereby providing space efficiency to the electronic device (501). In addition, since the conductive member is formed integrally with the side member, the third antenna element (533) may provide production efficiency and economy to the electronic device (501).

[0143] In one embodiment, the second antenna element (532) and the third antenna element (533) may be electrically isolated from each other. Each of the second antenna element (532) and the third antenna element (533) may independently receive signals.

[0144] In one embodiment, the first separation distance (D1) may be equal to half the wavelength (λ) of the positioning signal transmitted by the positioning target (e.g., the positioning signal (407) of FIG. 4) (e.g., λ / 2), or may be smaller than half the wavelength (λ) (e.g., λ / 2). Additionally, the second separation distance (D2) may be greater than half the wavelength (λ) of the positioning signal transmitted by the positioning target (e.g., λ / 2).

[0145] In one embodiment, the memory (130) may store a positioning algorithm based on a first separation distance (D1) and a second separation distance (D2). Alternatively, the memory (130) may store the first separation distance (D1) and the second separation distance (D2), and may also store an operation for setting a positioning algorithm using the first separation distance (D1) and the second separation distance (D2). The processor (120) may use the memory (130) to set or use the positioning algorithm.

[0146] In one embodiment of the present document, the electronic device (501) can improve the performance of measuring AoA with respect to a positioning target through a plurality of antenna elements (530) spaced apart by a first separation distance (D1) and a second separation distance (D2). For example, the electronic device (501) can expand the AoA measurement coverage. Alternatively, the electronic device (501) can improve the reliability and accuracy of AoA measurement.

[0147] In one embodiment of the present document, the arrangement design of the plurality of antenna elements (530) can be implemented in various ways, in a range where the plurality of antenna elements (530) are spaced apart by a first separation distance (D1) and a second separation distance (D2) along the third direction.

[0148] For example, although not shown in the drawing, each of the first antenna element (531), the second antenna element (532), and the third antenna element (533) may be formed of a conductive member that is spaced apart from the side member.

[0149] In one embodiment, the positions of the first antenna element (531), the second antenna element (532), and the third antenna element (533) are not limited and can be implemented in various ways within a range that forms a first separation distance (D1) and a second separation distance (D2) based on the third direction.

[0150] For example, the first antenna element (531) and the second antenna element (532) may be formed of conductive members that are provided adjacent to an area of ​​the side member that faces one direction (e.g., +Y direction). The third antenna element (533) may be formed of conductive members that are provided in an area of ​​the side member that faces another direction (e.g., -X direction).

[0151] Alternatively, for example, the first antenna element (531) may be made of a conductive member provided in a region of the side member facing one direction (e.g., +X direction), the second antenna element (532) may be made of a conductive member provided in a region of the side member facing another direction (e.g., +Y direction or -Y direction), and the third antenna element (533) may be made of a conductive member provided in a region of the side member facing another direction (e.g., -X direction).

[0152] A plurality of antenna elements (530) according to various embodiments of the present document can measure the AoA with a positioning target along the third direction based on the first direction by being spaced apart in a third direction. In addition, by being designed to be arranged in various ways within the limited space of the electronic device (501) and the substrate (520), the space efficiency of the electronic device (501) can be improved.

[0153] FIG. 7 is a graph illustrating a positioning algorithm (A1) according to an embodiment, FIG. 8 is a graph illustrating a positioning algorithm (A2) according to an embodiment, and FIG. 9 is a diagram illustrating AoA coverage of an electronic device (501) according to an embodiment.

[0154] For example, FIG. 7 is a graph illustrating a basic positioning algorithm (A1) based on a first separation distance (D1), FIG. 8 is a graph illustrating a correction positioning algorithm (A2) based on a second separation distance (D2), and FIG. 9 is a schematic diagram illustrating an extended range (e.g., R0 and Rm) of the AoA coverage of the electronic device (501) using the basic positioning algorithm (A1) and the correction positioning algorithm (A2).

[0155] Referring to FIGS. 7, 8, and 9, the processor (120) can expand the AoA coverage of the electronic device (501) using the basic positioning algorithm (A1) and the correction positioning algorithm (A2).

[0156] Hereinafter, any content overlapping with the above will be omitted for explanation, and it is to be understood that, in the electronic device (501), some configurations and structures may be replaced, added, or omitted within a range easily understandable to those skilled in the art by referring to the drawings and descriptions below. In addition, at least one configuration or feature of the embodiments described above may be combined in the electronic device (501) unless it is technically clearly impossible.

[0157] In addition, below, an electronic device (e.g., the electronic device (101) of FIG. 1, the electronic device (301) of FIGS. 3A, 3B, and 3C, the electronic device (401) of FIG. 4, the electronic device (501) of FIG. 5, or the electronic device (501) of FIG. 6) including a plurality of antenna elements (e.g., the plurality of antenna elements (530) of FIG. 5 or 6) measures an AoA with a positioning target (e.g., the positioning target (405) of FIG. 4) using signals received from each of the plurality of antenna elements (530) will be exemplarily described. However, in the actual implementation of the electronic device (501), the positioning of the electronic device (501) is not limited thereto, and various operations and information may be modified, changed, omitted, and / or replaced.

[0158] In one embodiment, a processor of an electronic device (501) (e.g., processor (120) of FIG. 1) can measure an AoA with a positioning target by using a phase difference of a plurality of signals received by a plurality of antenna elements (530).

[0159] In one embodiment, the processor (120) may receive a signal for a positioning signal using a plurality of antenna elements (530). The processor (120) may identify a phase difference of at least some of a first signal received from a first antenna element (e.g., the first antenna element (531) of FIG. 5 or 6), a second signal received from a second antenna element (e.g., the second antenna element (532) of FIG. 5 or 6), and a third signal received from a third antenna element (e.g., the third antenna element (533) of FIG. 5 or 6).

[0160] FIG. 7 may be a graph illustrating a basic positioning algorithm (A1) based on a first separation distance (D1) according to one embodiment, and FIG. 8 may be a graph illustrating a correction positioning algorithm (A2) based on a second separation distance (D2).

[0161] In FIG. 7, the input may be the phase difference between the first signal and the second signal, and in FIG. 8, the input may be the phase difference between the first signal and the third signal. In addition, the output of FIGS. 7 and 8 may be the expected values ​​of the AoA of the electronic device (501) and the positioning target according to the basic positioning algorithm (A1) and the corrected positioning algorithm (A2).

[0162] The angle of the output of FIGS. 7 and 8 is a measurement of the direction of the positioning target based on the reference line (l) of FIG. 9, and when explained based on the first direction of the electronic device (501) and the substrate (520) described above in FIGS. 5 and 6, 0 degrees may represent a direction that matches the reference line (l) or the first direction, +90 degrees may represent a third direction (or a fourth direction opposite to the third direction) in which a plurality of antenna elements (530) are arranged, and -90 degrees may represent a fourth direction (or a third direction) opposite to the third direction.

[0163] Although Figures 7 and 8 illustrate the basic positioning algorithm (A1) and the correction positioning algorithm (A2) as substantially flat linear lines, this may be a schematic representation for convenience of explanation or may be the result of performing separate flattening.

[0164] In one embodiment, the basic positioning algorithm (A1) may have reduced reliability and / or accuracy within the correction angle range (Rm). If the processor (120) determines that the measured AoA falls within the preset correction angle range (Rm), the processor (120) may correct the AoA using the correction angle algorithm (A2). The correction angle range (Rm) may include a first correction range (R1) and a second correction range (R2).

[0165] For example, in the output of the basic positioning algorithm (A1) based on the first separation distance (D1) of FIG. 7, it can be confirmed that the input-output change of the basic positioning algorithm (A1) has a high resolution in the basic positioning range (R0) adjacent to 0 degrees, whereas the input-output change has a relatively low resolution in the first correction range (R1) and second correction range (R2) that exceed the basic positioning range (R0).

[0166] In addition, for example, in the output of the correction positioning algorithm (A2) based on the second separation distance (D2) of Fig. 8, it can be confirmed that the input-output change of the correction positioning algorithm (A2) in each of the first correction range (R1) and the second correction range (R2) has a high resolution. In addition, since the input-output values ​​of the mutual mountains in the first correction range (R1) and the second correction range (R2) do not overlap, one output can be derived from one input, except for the basic positioning range (R0).

[0167] In one embodiment of the present document, if the processor (120) of the electronic device (501) determines that the measured AoA falls within a preset correction angle range (Rm), the processor (120) can correct the measured AoA using the phase difference of the first signal and the third signal and the correction positioning algorithm (A2).

[0168] Referring to FIG. 9, the basic positioning range (R0) may be a range in which the AoA with the positioning target is measured using the phase difference between the identified first and second signals and the basic positioning algorithm (A1) when the measured AoA does not fall within the correction angle range (Rm).

[0169] Additionally, the correction angle range (Rm) may be a range in which the AoA with the positioning target is measured using the phase difference of the identified first signal and third signal and the correction positioning algorithm (A2) when the measured AoA is outside the basic positioning range (R0) or falls within the preset correction angle range (Rm).

[0170] In one embodiment of the present document, the electronic device (501) can expand AoA coverage and improve AoA measurement reliability and accuracy by using the phase difference of signals received from a plurality of antenna elements (530) spaced apart by a first separation distance (D1) and a second separation distance (D2), and a basic positioning algorithm (A1) and a correction positioning algorithm (A2).

[0171] In one embodiment, the basic positioning range (R0) may be a range of approximately 60 degrees in the third and fourth directions relative to the first direction. For example, the first correction range (R1) may be a range of approximately 60 degrees to approximately 90 degrees in the third direction relative to the first direction. The second correction range (R2) may be a range of approximately 60 degrees to approximately 90 degrees in the fourth direction relative to the first direction. However, these are exemplary numerical ranges, and the numerical ranges may change depending on various elements of the electronic device (501).

[0172] FIG. 10a is a graph illustrating a positioning algorithm (A3) according to an embodiment, FIG. 10b is a graph illustrating a positioning algorithm (A4) according to an embodiment, and FIG. 11 is a diagram illustrating AoA coverage of an electronic device (501) according to an embodiment.

[0173] For example, FIG. 10a is a graph illustrating a synthetic positioning algorithm (A3) that synthesizes a positioning algorithm based on a first separation distance (D1) (e.g., the basic positioning algorithm (A1) of FIG. 7) and a positioning algorithm based on a second separation distance (D2) (e.g., the corrected positioning algorithm (A2) of FIG. 8), FIG. 10b is a graph illustrating a meta positioning algorithm (A4) that scales the synthetic positioning algorithm (A3), and FIG. 11 is a schematic diagram illustrating a range (R3) in which the AoA coverage of the electronic device (501) is expanded using the meta positioning algorithm (A4).

[0174] Referring to FIGS. 10A, 10B and 11, the processor (120) can expand the AoA coverage of the electronic device (501) using the meta-positioning algorithm (A4).

[0175] Hereinafter, any content overlapping with the above will be omitted for explanation, and it is to be understood that, in the electronic device (501), some configurations and structures may be replaced, added, or omitted within a range easily understandable to those skilled in the art by referring to the drawings and descriptions below. In addition, at least one configuration or feature of the embodiments described above may be combined in the electronic device (501) unless it is technically clearly impossible.

[0176] In addition, below, an electronic device (e.g., the electronic device (101) of FIG. 1, the electronic device (301) of FIGS. 3A, 3B, and 3C, the electronic device (401) of FIG. 4, the electronic device (501) of FIG. 5, or the electronic device (501) of FIG. 6) including a plurality of antenna elements (e.g., the plurality of antenna elements (530) of FIG. 5 or 6) measures an AoA with a positioning target (e.g., the positioning target (405) of FIG. 4) using signals received from each of the plurality of antenna elements (530) will be exemplarily described. However, in the actual implementation of the electronic device (501), the positioning of the electronic device (501) is not limited thereto, and various operations and information may be modified, changed, omitted, and / or replaced.

[0177] In one embodiment, a processor of an electronic device (501) (e.g., processor (120) of FIG. 1) can measure an AoA with a positioning target by using a phase difference of a plurality of signals received by a plurality of antenna elements (530).

[0178] In one embodiment, the processor (120) may receive a signal for a positioning signal using a plurality of antenna elements (530). The processor (120) may identify a phase difference of at least a portion of a first signal received from a first antenna element (e.g., the first antenna element (531) of FIG. 5 or 6), a second signal received from a second antenna element (e.g., the second antenna element (532) of FIG. 5 or 6), and a third signal received from a third antenna element (e.g., the third antenna element (533) of FIG. 5 or 6).

[0179] FIG. 10a may be a graph of a synthetic positioning algorithm (A3) formed by synthesizing a positioning algorithm (e.g., basic positioning algorithm (A1)) based on a first separation distance (D1) and a positioning algorithm (e.g., corrected positioning algorithm (A2)) based on a second separation distance (D2), and FIG. 10b may be a graph formed by scaling (e.g., 1 / 2) the synthetic positioning algorithm (A3).

[0180] In one embodiment, the meta-positioning algorithm (A4) can be formed by overlapping and scaling a positioning algorithm based on a first separation distance (D1) (e.g., the basic positioning algorithm (A1) of FIG. 7) and a positioning algorithm based on a second separation distance (D2) (e.g., the corrected positioning algorithm (A2) of FIG. 8).

[0181] In FIG. 10b, the input of the meta-positioning algorithm (A4) may be a scaling value (e.g., 1 / 2) of the phase difference between the first and second signals and the sum of the phase differences between the first and third signals. In addition, the output of the meta-positioning algorithm (A4) in FIG. 10b may be an estimated value of the AoA of the electronic device (501) and the positioning target.

[0182] The angle of the output of FIG. 10b is a measurement of the direction of the positioning target based on the reference line (l) of FIG. 11, and when explained based on the first direction of the electronic device (501) and the substrate (520) described above in FIGS. 5 and 6, 0 degrees may represent a direction that matches the reference line (l) or the first direction, +90 degrees may represent a third direction (or a fourth direction opposite to the third direction) in which a plurality of antenna elements (530) are arranged, and -90 degrees may represent a fourth direction (or a third direction) opposite to the third direction.

[0183] Figure 10b depicts the meta-positioning algorithm (A4) as a substantially flat linear line, but this may be a schematic representation for convenience of explanation or the result of performing separate flattening.

[0184] In one embodiment, the processor (120) can measure the AoA using a meta-positioning algorithm (A4) based on a first separation distance (D1) and a second separation distance (D2) and a phase difference between the identified first signal and the identified second signal and a phase difference between the identified first signal and the identified third signal.

[0185] For example, in the output of the meta-positioning algorithm (A4), compared to the basic positioning algorithm (A1) of Fig. 7, it can be confirmed that the input-output change in the output range area (R3) has a high resolution.

[0186] In one embodiment, the processor (120) of the electronic device (501) may use a meta-positioning algorithm (A4) stored in the memory (130), or may generate a meta-positioning algorithm (A4) based on the first separation distance (D1) and the second separation distance (D2).

[0187] In one embodiment of the present document, the electronic device (501) can expand AoA coverage and improve AoA measurement reliability and accuracy by using the phase difference of signals received from multiple antenna elements (530) and the meta-positioning algorithm (A4).

[0188] FIG. 12 is a flowchart illustrating a control method (600) of an electronic device (501) according to one embodiment.

[0189] Referring to FIG. 12, a control method (600) of an electronic device (501) according to one embodiment may include at least some of an operation (610) of receiving a signal from a plurality of antenna elements (530), a phase difference identification operation (620), and an AoA measurement operation (630).

[0190] Hereinafter, any content overlapping with the above will be omitted for explanation, and it is to be understood that some configurations, structures, or operations may be replaced, added, or omitted within a range that can be easily understood by those skilled in the art by referring to the drawings and descriptions below in the electronic device (501) and the control method of the electronic device (501). In addition, at least one configuration, operation, or feature of the above-described embodiments may be combined in the electronic device (501) and the control method of the electronic device (501), unless it is technically clearly impossible.

[0191] In one embodiment, the operation (610) of receiving a signal from a plurality of antenna elements (530) may include a first signal receiving operation (611), a second signal receiving operation (612), and a third signal receiving operation (613). The first signal receiving operation (611), the second signal receiving operation (612), and the third signal receiving operation (613) may be performed independently of each other, without any precedence restrictions, or at least some of them may be performed simultaneously.

[0192] In one embodiment, the first signal receiving operation (611) may receive a first signal for a positioning signal from the first antenna element (531). The second signal receiving operation (612) may receive a second signal for the positioning signal from the second antenna element (532) which is arranged at a first separation distance (D1) based on a preset separation direction from the first antenna element (531). For example, the first antenna element (531) and the second antenna element (532) may be arranged at a first separation distance (D1) in a direction perpendicular to the first direction on the first surface (521) of the substrate (520) facing the first direction.

[0193] In one embodiment, the third signal receiving operation (613) may receive a third signal for a positioning signal from a third antenna element (533) that is spaced apart from the first antenna element (531) by a second separation distance (D2) greater than the first separation distance (D1) based on the separation direction and is electrically isolated from the second antenna element (532). For example, the first antenna element (531) and the third antenna element (533) may be spaced apart from each other by the second separation distance (D2) in a direction perpendicular to the first direction on the first surface (521) of the substrate (520) facing the first direction.

[0194] In one embodiment, the phase difference identification operation (620) can identify a phase difference of arriving signal (PDoA) of at least some of the first signal, the second signal, and the third signal.

[0195] In one embodiment, the AoA measurement operation (630) may measure the AoA (angle of arrival) from the electronic device (501) to the positioning target by using the phase difference between the first signal and the second signal identified in the phase difference identification operation (620) and the phase difference between the first signal and the third signal.

[0196] In one embodiment of the present document, a control method (600) of an electronic device (501) can identify a phase difference between signals received by at least two antenna elements (530) spaced apart by a first separation distance (D1) and a second separation distance (D2), and perform AoA measurement by utilizing the phase difference. The control method (600) of the electronic device (501) can improve reliability and / or accuracy, and can expand the AoA coverage of the electronic device (501).

[0197] FIG. 13 is a flowchart illustrating some operations of a control method (600) of an electronic device (501) according to one embodiment.

[0198] Referring to FIG. 13, an AoA measurement operation (630) according to one embodiment may include at least some of an operation (631) of measuring AoA using a basic positioning algorithm (A1) and an operation (635) of measuring AoA using a correction positioning algorithm (A2).

[0199] Hereinafter, any content overlapping with the above will be omitted for explanation, and in the electronic device (501) and the control method (600) of the electronic device (501), some configurations, structures, or operations may be replaced, added, or omitted within a range that can be easily understood by those skilled in the art with reference to the drawings and descriptions below. In addition, at least one configuration, operation, or feature of the embodiments described above may be combined in the electronic device (501) and the control method (600) of the electronic device (501), unless it is technically clearly impossible.

[0200] In one embodiment, the operation (631) of measuring AoA using a basic positioning algorithm (A1) may measure an AoA (angle of arrival) with a positioning target using a basic positioning algorithm (A1) based on a first separation distance (D1) and a phase difference between the identified first signal and the second signal.

[0201] In one embodiment, the AoA measurement operation (630) may further include an operation (633) of determining whether the measured AoA falls within a correction angle range (Rm) using the basic positioning algorithm (A1).
