Description

Technical Field

[0001] The present disclosure relates to an electronic device including a helical antenna. Background Art

[0002] As electronic devices such as smartphones have an increasingly wide range of available applications, the number of antennas included in the electronic devices continues to increase. In recent years, the trend of such electronic devices has been to achieve specified performance while pursuing a slim form factor. Summary of the invention

[0003] Technical issues

[0004] The electronic device may include, for example, a back plate forming its back surface and a helical antenna (e.g., a helical conductive pattern) disposed therein near the back plate. The helical antenna may be surrounded by various conductive members, and while reducing the degradation of antenna radiation performance due to the conductive members, it becomes more difficult to design the helical antenna in a limited space due to the thinness of the electronic device.

[0005] Solution to the problem

[0006] Embodiments of the present disclosure provide an electronic device including a helical antenna that improves and / or ensures radiation performance by disposing a plurality of magnetic sheets.

[0007] According to various example embodiments of the present disclosure, an electronic device includes: a housing including a front panel and a rear panel disposed opposite to the front panel; a display disposed in a space between the front panel and the rear panel and visible through at least a portion of the front panel; an antenna structure including at least one coil, having a first surface facing the rear panel in the space and a second surface facing a direction opposite to the first surface, the antenna structure being configured to send and / or receive signals of a selected or specified frequency; a first magnetic sheet disposed at the first surface; a second magnetic sheet at least partially overlapping the first magnetic sheet when viewed from above the rear panel, the second magnetic sheet being disposed at the second surface; and a third magnetic sheet disposed closer to the rear panel than the second surface and spaced apart from the first magnetic sheet when viewed from above the rear panel to have an electromagnetically specified isolation from the first magnetic sheet and with the second magnetic sheet interposed therebetween.

[0008] Advantageous Effects of the Invention

[0009] According to various exemplary embodiments of the present disclosure, by arranging a helical antenna (e.g., a helical conductive pattern) near a rear panel and arranging a plurality of magnetic sheets around the helical antenna to absorb and / or shield noise from the outside, the radiation performance of the helical antenna can be ensured. In addition, even if the size of the helical antenna is reduced, the radiation performance of the helical antenna can be ensured due to the electromagnetic interaction between the plurality of magnetic sheets. Since the size of the helical antenna can be reduced while ensuring the radiation performance, the space occupied by the battery can be easily ensured in order to increase the battery capacity or make the electronic device slim.

[0030] Reference Figure 1, the electronic device 101 in the network environment 100 may communicate with the electronic device 102 via the first network 198 (e.g., a short-range wireless communication network), or communicate with the electronic device 104 or the server 108 via the second network 199 (e.g., a long-range wireless communication network). The electronic device 101 may communicate with the electronic device 104 via the server 108. The electronic device 101 includes a processor 120, a memory 130, an input device 150, a sound output device 155, a display device 160, an audio module 170, a sensor module 176, an interface 177, a haptic module 179, a camera module 180, a power management module 188, a battery 189, a communication module 190, a user identification module (SIM) 196, or an antenna module 197. In some embodiments, at least one of the components (e.g., the display device 160 or the camera module 180) may be omitted from the electronic device 101, or one or more other components may be added to the electronic device 101. In some embodiments, some of the components may be implemented as a single integrated circuit. For example, the sensor module 176 (eg, a fingerprint sensor, an iris sensor, or an illumination sensor) may be implemented to be embedded in the display device 160 (eg, a display).

[0031] The processor 120 may run, for example, software (e.g., program 140) to control at least one other component (e.g., hardware component or software component) of the electronic device 101 connected to the processor 120, and may perform various data processing or calculations. As at least part of the data processing or calculation, the processor 120 may load commands or data received from another component (e.g., sensor module 176 or communication module 190) into the volatile memory 132, process the commands or data stored in the volatile memory 132, and store the resultant data in the non-volatile memory 134. The processor 120 may include a main processor 121 (e.g., a central processing unit (CPU) or an application processor (AP)) and an auxiliary processor 123 (e.g., a graphics processing unit (GPU), an image signal processor (ISP), a sensor hub processor, or a communication processor (CP)) that is operationally independent or combined with the main processor 121. Additionally or alternatively, the auxiliary processor 123 may be adapted to consume less power than the main processor 121, or adapted to be specifically used for a specified function. The auxiliary processor 123 may be implemented separately from the main processor 121 , or as part of the main processor 121 .

[0032] When the main processor 121 is in an inactive (e.g., sleep) state, the auxiliary processor 123 may control at least some of the functions or states related to at least one component (e.g., display device 160, sensor module 176, or communication module 190) among the components of the electronic device 101 instead of the main processor 121, or when the main processor 121 is in an active state (e.g., running an application), the auxiliary processor 123 may control at least some of the functions or states related to at least one component (e.g., display device 160, sensor module 176, or communication module 190) among the components of the electronic device 101 together with the main processor 121. The auxiliary processor 123 (e.g., ISP or CP) may be implemented as part of another component (e.g., camera module 180 or communication module 190) that is functionally related to the auxiliary processor 123.

[0033] The memory 130 may store various data used by at least one component of the electronic device 101 (e.g., the processor 120 or the sensor module 176).

[0035] The input device 150 may receive commands or data from outside the electronic device 101 (e.g., a user) to be used by other components of the electronic device 101 (e.g., the processor 120). The input device 150 may include, for example, a microphone, a mouse, a keyboard, or a digital pen (e.g., a stylus).

[0036] The sound output device 155 can output sound signals to the outside of the electronic device 101. The sound output device 155 may include, for example, a speaker or a receiver.

The receiver can be implemented as a separate part from the speaker, or as part of the speaker.

[0037] The display device 160 may visually provide information to the outside of the electronic device 101 (e.g., a user). The display device 160 may include, for example, a display, a holographic device, or a projector, and a control circuit for controlling a corresponding one of the display, the holographic device, and the projector. The display device 160 may include a touch circuit adapted to detect a touch or a sensor circuit (e.g., a pressure sensor) adapted to measure the strength of a force caused by a touch.

[0038] The audio module 170 can convert sound into an electrical signal, or vice versa. The audio module 170 can obtain sound via the input device 150, or output sound via the sound output device 155 or an earphone of an external electronic device (e.g., electronic device 102) directly (e.g., wired) or wirelessly connected to the electronic device 101.

[0039] The sensor module 176 may detect an operating state (e.g., power or temperature) of the electronic device 101 or an environmental state (e.g., a user's state) outside the electronic device 101, and then generate an electrical signal or data value corresponding to the detected state. The sensor module 176 may include, for example, a gesture sensor, a gyro sensor, an atmospheric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an infrared (IR) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illumination sensor.

[0040] The interface 177 may support one or more specific protocols to be used to connect the electronic device 101 directly (e.g., wired) or wirelessly with an external electronic device (e.g., the electronic device 102). The interface 177 may include, for example, a high-definition multimedia interface (HDMI), a universal serial bus (USB) interface, a secure digital (SD) card interface, or an audio interface.

[0041] The connection end 178 may include a connector, wherein the electronic device 101 can be physically connected to an external electronic device (e.g., the electronic device 102) via the connector. The connection end 178 may include, for example, an HDMI connector, a USB connector, an SD card connector, or an audio connector (e.g., a headphone connector).

[0042] The haptic module 179 may convert the electrical signal into mechanical stimulation (eg, vibration or motion) or electrical stimulation that can be recognized by the user via his sense of touch or kinesthetic sense. The haptic module 179 may include, for example, a motor, a piezoelectric element, or an electrical stimulator.

[0043] The camera module 180 may capture still images or moving images. The camera module 180 may include one or more lenses, an image sensor, an image signal processor, or a flash.

[0044] The power management module 188 may manage power supply to the electronic device 101. The power management module 188 may be implemented as, for example, at least a portion of a power management integrated circuit (PMIC).

[0045] The battery 189 may power at least one component of the electronic device 101. The battery 189 may include, for example, a non-rechargeable primary battery, a rechargeable secondary battery, or a fuel cell.

[0046] The communication module 190 may support establishing a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device 101 and an external electronic device (e.g., electronic device 102, electronic device 104, or server 108), and perform communication via the established communication channel. The communication module 190 may include one or more communication processors that can operate independently from the processor 120 (e.g., AP) and support direct (e.g., wired) communication or wireless communication. 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 (PLC) module). A corresponding one of these communication modules can communicate with an external electronic device via a first network 198 (e.g., a short-range communication network such as Bluetooth, Wireless Fidelity (Wi-Fi) Direct, or Infrared Data Association (IrDA) standards) or a second network 199 (e.g., a long-range communication network such as a cellular network, the Internet, or a computer network (e.g., a LAN or a wide area network (WAN))). These various types of communication modules can be implemented as a single component (e.g., a single chip), or these various types of communication modules can be implemented as multiple components separated from each other (e.g., multiple chips). The wireless communication module 192 can identify and authenticate the electronic device 101 in a communication network (such as the first network 198 or the second network 199) using user information (e.g., an International Mobile Subscriber Identity (IMSI)) stored in the SIM 196.

[0047] The antenna module 197 may transmit or receive a signal or power to or from the outside of the electronic device 101 (e.g., an external electronic device). The antenna module 197 may include an antenna including a radiating element including a conductive material or a conductive pattern formed in or on a substrate (e.g., a PCB). The antenna module 197 may include a plurality of antennas. In this case, at least one antenna suitable for a communication scheme used in a communication network (such as the first network 198 or the second network 199) may be selected from the plurality of antennas by, for example, the communication module 190 (e.g., the wireless communication module 192). A signal or power may then be transmitted or received between the communication module 190 and the external electronic device via the selected at least one antenna. Additional components other than the radiating element (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as part of the antenna module 197.

[0048] At least some of the above components may be connected to each other via an inter-peripheral communication scheme (e.g., a bus, general purpose input output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)) and communicatively transmit signals (e.g., commands or data) therebetween.

[0049] A command or data may be sent or received between the electronic device 101 and the external electronic device 104 via the server 108 connected to the second network 199. Each of the electronic device 102 and the electronic device 104 may be a device of the same type as the electronic device 101, or a device of a different type from the electronic device 101. All or some operations to be executed in the electronic device 101 may be executed in one or more of the external electronic device 102, the external electronic device 104, or the server 108. For example, if the electronic device 101 should automatically execute a function or service or should execute a function or service in response to a request from a user or another device, the electronic device 101 may request the one or more external electronic devices to execute at least part of the function or service instead of executing the function or service, or the electronic device 101 may request the one or more external electronic devices to execute at least part of the function or service in addition to executing the function or service. The one or more external electronic devices that receive the request may execute the requested at least part of the function or service, or execute another function or another service related to the request, and transmit the result of the execution to the electronic device 101. The electronic device 101 may provide the result as at least a partial reply to the request with or without further processing the result. To this end, for example, cloud computing technology, distributed computing technology, or client-server computing technology may be used.

For example, the conductive pattern of the antenna structure 370 (e.g., the first conductive pattern 510) may have a resonant frequency substantially the same as the resonant frequency of the antenna (e.g., coil) of the external electronic device for transmitting and receiving power. Utilizing the resonance phenomenon between the conductive pattern of the antenna structure 370 and the antenna for power transmission and reception of the external electronic device, the power transmission / reception circuit may wirelessly receive power from the external electronic device or may wirelessly transmit power to the external electronic device. The electromagnetic resonance type power transmission / reception circuit may follow, for example, the A4WP (Wireless Charging Alliance) standard. Using a resonant frequency of approximately 6.78 MHz, the electromagnetic resonance type power transmission / reception circuit according to the A4WP standard may wirelessly receive power from an external electronic device or may wirelessly transmit power to an external electronic device.

[0124] According to an embodiment, the antenna structure 370 may include a coil inner region (or coil interior) 540. The coil inner region 540 may refer to, for example, an area surrounded by the first coil portion 513 of the first conductive pattern 510. According to an embodiment, the first coil portion 513 may be disposed around the rectangular coil inner region 540 and form, for example, a square planar spiral coil. When a radiation current is supplied to the first conductive pattern 510, a magnetic force generated in the first conductive pattern 510 may pass through the coil inner region 540.

[0125] According to various embodiments (not shown), the coil inner region 540 may be implemented in various other forms such as a circle, not limited to a rectangle. The first conductive pattern 510 may be implemented with a planar spiral coil of various shapes according to the shape of the coil inner region 540 .

[0126] According to an embodiment, the second coil portion 523 of the second conductive pattern 520 may be disposed outside the first coil portion 513 of the first conductive pattern 510. According to various embodiments, when radiation current is supplied to the second conductive pattern 520, magnetic force generated in the second conductive pattern 520 may pass through the coil inner region 540.

According to an embodiment, the first magnetic sheet 610 may be provided at the first surface 370a of the antenna structure 370 or attached to the first surface 370a of the antenna structure 370 (see, for example, Figure 4 According to example embodiments, the second magnetic sheet 620 may be disposed at the second surface 370 b of the antenna structure 370 or attached to the second surface 370 b of the antenna structure 370 .

[0129] According to an embodiment, when viewed from above the first surface 370a of the antenna structure 370 (for example, when viewed in the z-axis direction), the first magnetic sheet 610 and the second magnetic sheet 620 may be arranged to partially overlap. Figure 5 The first magnetic sheet 610 may include a first magnetic sheet 610 disposed on the inner side of the coil 540.

Figure 5 The third portion 621 in the coil inner region 540 and the fourth portion 622 extending from the third portion 621. When viewed from above the first surface 370a of the antenna structure 370, the first portion 611 and the third portion 621 may overlap at least partially. When viewed from above the first surface 370a of the antenna structure 370, the second portion 612 may be disposed between the first portion 611 and the first side portion 411. When viewed from above the first surface 370a of the antenna structure 370, the fourth portion 622 may be disposed between the third portion 621 and the battery 350. According to an embodiment, in the direction between the third side portion 413 and the fourth side portion 414 (e.g., the x-axis direction), the second portion 612 may have a width greater than that of the first portion 611.

[0131] Reference Figure 7 In an example embodiment, the electronic device 200 may include a housing (eg, Figure 2A The housing includes a front panel 202, a rear panel 211 and a side member 218 forming an external shape of the electronic device, and the first support member 311 is arranged in the internal space of the housing.

[0132] According to example embodiments, the second electrical path 460 may electrically connect the first substrate assembly 341 and the second substrate assembly 342. The second electrical path 460 may be disposed across between the battery 350 and the rear plate 211, for example.

[0133] According to an embodiment, the antenna structure 370 may be provided between the first substrate assembly 341 and the rear plate 211. The antenna structure 370 may be implemented in, for example, a film form. When viewed from above the rear plate 211 (for example, when viewed in the +z-axis direction), the antenna structure 370 may be provided so as not to overlap with the battery 350. According to an embodiment, the antenna structure 370 may be provided at a second support member 361 for covering at least a portion of the first substrate assembly 341.

[0134] According to an example embodiment, the antenna structure 370 may include a first surface 370a facing the rear plate 211 and a second surface 370b disposed on a side opposite to the first surface 370a and facing the second support member 361. The first magnetic sheet 610 may be disposed at the first surface 370a of the antenna structure 370. The second magnetic sheet 620 may be disposed at the second surface 370b of the antenna structure 370. According to an embodiment, when viewed from above the rear plate 211, the first magnetic sheet 610 and the second magnetic sheet 620 may be disposed at the second surface 370b of the antenna structure 370. Figure 5 The coils partially overlap each other in the inner region 540 .

[0135] According to an embodiment, the third magnetic sheet 700 may be disposed at the rear plate 211 between the battery 350 and the rear plate 211. Figure 4 and Figure 7 , when viewed from above the rear plate 211, the third magnetic sheet 700 may be arranged to at least partially overlap the first electrical path 450 and / or the second electrical path 460. The third magnetic sheet 700 may reduce the transmission of noise to the first electrical path 450 and the second electrical path 460. For example, the third magnetic sheet 700 may prevent noise from an external electronic device from reaching the first electrical path 450 and / or the second electrical path 460 through the rear plate 211. For example, when the electronic device 200 is mounted on the wireless charging device, the third magnetic sheet 700 may reduce the electrical shock (e.g., noise) applied by the wireless charging device to the first electrical path 450 and / or the second electrical path 460. By means of noise shielding by the third magnetic sheet 700, the integrity of the signal transmitted through the first electrical path 450 and / or the second electrical path 460 may be ensured.

[0136] According to an embodiment, the third magnetic sheet 700 may be disposed closer to the rear plate 211 in the -z direction than the second magnetic sheet 620. For example, the second magnetic sheet 620 may be disposed farther from the rear plate 211 in the +z-axis direction than the first magnetic sheet 610 and the third magnetic sheet 700. The third magnetic sheet 700 may be spaced apart from the first magnetic sheet 610 in the -y-axis direction.

[0137] According to various embodiments, the third magnetic sheet 700 may be implemented in the form of a one-piece FPCB having the first electrical path 450 and / or the second electrical path 460. According to various embodiments, the third magnetic sheet 700 may be attached to the FPCB including the first electrical path 450 and / or the second electrical path 460.

[0138] Figure 8 is a diagram showing the Figure 7 A cross-sectional view of an example antenna structure associated with antenna structure 370 in electronic device 200.

[0139] According to an example embodiment, the antenna structure 370 may include Figure 4The first region 810 of the first conductive pattern 510 and the Figure 4 The second region 820 of the second conductive pattern 520 may have a shape surrounding the first region 810 when viewed from above the rear plate 211 .

[0140] According to an embodiment, the first area 810 may transmit and / or receive a first signal in a first frequency band. The second area 820 may transmit and / or receive a second signal in a second frequency band different from the first frequency band. For example, the first signal may have a frequency associated with MST, and the second signal may have a frequency associated with NFC.

[0141] According to example embodiments, an antenna or an antenna system using the antenna structure 370 may include a first antenna structure in which the first magnetic sheet 610 and the second magnetic sheet 620 are partially overlapped when viewed from above the rear plate 211 (e.g., when viewed in the +z-axis direction) while the first magnetic sheet 610 is disposed at the first surface 370a of the antenna structure 370 and the second magnetic sheet 620 is disposed at the second surface 370b of the antenna structure 370. According to the first antenna structure, the second magnetic sheet 620 may be disposed closer to the third magnetic sheet 700 in the -y-axis direction than the first magnetic sheet 610.

[0142] According to example embodiments, an antenna or an antenna system using the antenna structure 370 may include a second antenna structure in which the third magnetic sheet 700 is disposed at a third surface 211b spaced apart from the second surface 370b of the antenna structure 370 toward the rear plate 211, and is spaced apart from the first magnetic sheet 610 when viewed from above the rear plate 211, and the second magnetic sheet 620 is interposed between the first magnetic sheet 610 and the second antenna structure. According to the second antenna structure, when viewed from above the rear plate 211, the second magnetic sheet 620 may include one end portion (e.g., Figure 6 The third portion 621) and another end portion extending from the one end portion and adjacent to the third magnetic sheet 700 (eg, Figure 6 According to example embodiments, the third surface 211b may be formed by the rear plate 211. According to the second antenna structure, the first magnetic sheet 610 and the third magnetic sheet 700 may be disposed closer to the rear plate 211 than the second magnetic sheet 620 in the -z axis direction.

[0143] According to some embodiments, the first magnetic sheet 610 may not be disposed at the antenna structure 370 but may be disposed at the rear plate 211 (eg, the third surface 211 b ).

[0144] According to an embodiment, the first magnetic sheet 610 may be arranged not to overlap with the second region 820 when viewed from above the rear plate 211. For example, when a signal of a frequency related to NFC is transmitted and / or received through the second region 820, if there is the first magnetic sheet 610 between the rear plate 211 and the second region 820, the radiation performance through the second region 820 may be degraded due to the first magnetic sheet 610; therefore, the first magnetic sheet 610 may be arranged not to overlap with the second region 820 for NFC.

[0145] According to example embodiments, the third magnetic sheet 700 may be disposed not to overlap with the second region 820 when viewed from above the rear plate 211 to ensure radiation performance for NFC. For example, when a signal of a frequency related to NFC is transmitted and / or received through the second region 820, if there is the third magnetic sheet 700 between the rear plate 211 and the second region 820, the radiation performance through the second region 820 may be degraded due to the third magnetic sheet 700; therefore, when viewed from the rear plate 211, the third magnetic sheet 700 may be disposed not to overlap with the second region 820 for NFC.

[0146] According to various embodiments, the second magnetic sheet 620 may extend to at least partially overlap the second region 820 when viewed from above the rear plate 211 (see reference numeral 623). The extended portion 623 of the second magnetic sheet 620 may shield noise. For example, Figure 7 The noise of the first substrate assembly 341 may be shielded by the extension portion 623 and thus be difficult to enter the second region 820 .

[0147] According to various embodiments, the spatial relationship between the second magnetic sheet 620 and the third magnetic sheet 700 may be changed by the extension portion 623. According to example embodiments, the extension portion 623 participates in the change of electromagnetic field characteristics caused by electromagnetic coupling between the second magnetic sheet 620 and the third magnetic sheet 700 to improve radiation performance.

[0148] According to example embodiments, when the electromagnetic field 801 is formed from the antenna structure 370, electromagnetic coupling between the first magnetic sheet 610 and the second magnetic sheet 620 and electromagnetic coupling between the second magnetic sheet 620 and the third magnetic sheet 700 may occur. According to an embodiment, the first antenna structure and the second antenna structure may enable the electromagnetic energy emitted from the antenna structure 370 to be concentrated in a specific direction in space to improve radiation performance. For example, the electromagnetic wave energy emitted from the antenna structure 370 may be concentrated in a direction (e.g., -z axis direction) substantially pointed to by the first surface 370a of the antenna structure 370 through the first antenna structure and the second antenna structure, or may be concentrated in a direction toward the rear plate 211, or may have directivity or directivity of sending or receiving waves. For example, by forming a preset boundary condition for the electromagnetic field from the antenna structure 370 via the first antenna structure and the second antenna structure, the electromagnetic wave energy may be guided in a specific direction. For example, the first antenna structure and the second antenna structure may propagate radio waves emitted from the antenna structure 370. For example, due to the electromagnetic coupling between the first magnetic sheet 610 and the second magnetic sheet 620, electromagnetic energy (see magnetic field line 802) may be formed to pass between the first magnetic sheet 610 and the second magnetic sheet 620 to be concentrated toward the rear plate 211. For example, due to the electromagnetic coupling between the second magnetic sheet 620 and the third magnetic sheet 700, electromagnetic energy (see magnetic field line 803) may be formed to pass through the second magnetic sheet 620 and the third magnetic sheet 700 to be concentrated toward the rear plate 211.

[0149] According to various embodiments, the first antenna structure and the second antenna structure may act as reflectors which increase the radiation in the direction of maximum radiation.

[0150] According to example embodiments, the first antenna structure and the second antenna structure reduce the Figure 7 The conductive medium at the periphery of the first substrate assembly 341 reduces the magnetic flux to ensure the radiation performance of the antenna structure 370. For example, when the reduction of the magnetic flux decreases, the electromagnetic wave energy increases due to the increase of the inductance value, thereby improving the radiation performance.

[0151] According to example embodiments, the first antenna structure and the second antenna structure reduce the Figure 7 The electromagnetic energy loss caused by eddy currents generated in peripheral elements (eg, metal components or integrated circuits) of the first substrate assembly 341 is reduced, thereby ensuring the radiation performance of the antenna structure 370 .

[0152] According to various embodiments, in a section where the first magnetic sheet 610 and the second magnetic sheet 620 partially overlap in the coil inside region 540 , a change in electromagnetic field characteristics due to electromagnetic coupling between the first magnetic sheet 610 and the second magnetic sheet 620 may occur.

[0153] According to an embodiment, the third magnetic sheet 700 may be provided to be electromagnetically coupled to the second magnetic sheet 620. When viewed from above the rear plate 211, a distance D1 between the third magnetic sheet 700 and the second magnetic sheet 620 may be formed such that electromagnetic coupling between the third magnetic sheet 700 and the second magnetic sheet 620 is possible. According to various embodiments, the distance D1 may be formed based on the wavelength of the radio wave emitted from the antenna structure 370 so that the third magnetic sheet 700 and the second magnetic sheet 620 are not electromagnetically isolated.

[0154] For example, refer to Figure 4 and Figure 5 , when viewed from above the first surface 370a of the antenna structure 370, the coil inner region 540 may include a first boundary 540a, a second boundary 540b disposed on a side opposite to the first boundary 540a, a third boundary 540c connecting one end of the first boundary 540a and one end of the second boundary 540b, and a fourth boundary 540d connecting the other end of the first boundary 540a and the other end of the second boundary 540b and disposed on a side opposite to the third boundary 540c. In an example embodiment, the first boundary 540a may be disposed closer to the first side portion 411 than the second boundary 540b, and the second boundary 540b may be disposed closer to the battery 350 than the first boundary 540a. The third boundary 540c may be disposed closer to the third side portion 413 than the fourth boundary 540d, and the fourth boundary 540d may be disposed closer to the fourth side portion 414 than the third boundary 540c. The first region 810 (or the first coil portion 513) may include a first pattern portion 513a between the first boundary 540a and the first side portion 411, a second pattern portion 513b between the second boundary 540b and the battery 350, a third pattern portion 513c between the third boundary 540c and the third side portion 413, or a fourth pattern portion 513d between the fourth boundary 540d and the fourth side portion 414. According to an embodiment, the second pattern portion 513b may have a first width W extending in a direction (e.g., -y axis direction) from the second boundary 540b toward the battery 350. For example, the first width W may refer to, for example, the width of the first coil portion 513 in the -y axis direction from the coil inner region 540. According to an embodiment, referring to Figure 5 and Figure 8 , when viewed from above the rear plate 211 , the distance D1 may be formed within a length that is approximately twice the length of the first width W. For example, the distance D1 may be approximately 20 mm or less.

[0155] According to an embodiment, when the third magnetic sheet 700 is arranged parallel to the second magnetic sheet 620, it may be difficult to ensure the radiation performance of the antenna structure 370. The third magnetic sheet 700 and the second magnetic sheet 620 may be substantially parallel to each other and spaced apart from each other, but such a setting structure may cause the loss (e.g., leakage) of electromagnetic energy through the electromagnetic coupling between the second magnetic sheet 620 and the third magnetic sheet 700. For example, it may be difficult for two magnetic sheets (e.g., the first magnetic sheet 610 and the third magnetic sheet 700) arranged on the same plane at an electromagnetic coupling distance to guide electromagnetic energy in a specific direction. According to an example embodiment, the third magnetic sheet 700 may be closer to the rear plate 211 than the second magnetic sheet 620 in the -z axis direction and spaced apart from the first magnetic sheet 610 in the -y axis direction to ensure the radiation performance.

[0156] According to some embodiments (not shown), the first magnetic sheet 610 is disposed at the first surface 370a of the antenna structure 370, and the second magnetic sheet 620 is disposed at the second surface 370b of the antenna structure 370, but can be arranged not to overlap each other when viewed from above the back plate 211 to achieve electromagnetic coupling.

[0157] According to example embodiments, the first magnetic sheet 610, the second magnetic sheet 620, and / or the third magnetic sheet 700 may be implemented with various magnetic materials related to the magnetic flux or frequency associated with the antenna structure 370 to improve the radiation performance through the first antenna structure and the second antenna structure. According to various embodiments, the magnetic material may include various conductive materials and / or non-conductive materials having magnetic properties. For example, the material constituting the first magnetic sheet 610, the second magnetic sheet 620, and / or the third magnetic sheet 700 may be selected based on the frequency of the signal sent and / or received through the first area 810. According to an embodiment, the first magnetic sheet 610, the second magnetic sheet 620, and / or the third magnetic sheet 700 may be made of a material having a relatively high dielectric constant and / or magnetic permeability at the frequency of the signal sent and / or received through the first area 810. According to an embodiment, the first magnetic sheet 610, the second magnetic sheet 620, and / or the third magnetic sheet 700 may be made of a material having a relatively high electromagnetic shielding property or electromagnetic diffusion property at the frequency of the signal sent and / or received through the first area 810.

[0158] For example, the first magnetic sheet 610, the second magnetic sheet 620 and / or the third magnetic sheet 700 can be implemented as nanosheets having a relatively high dielectric constant in a frequency of about 200kHz or less (e.g., about 70kHz) associated with the MST using the first region 810. A nanosheet can refer to, for example, a magnetic sheet formed using a nanocrystalline alloy with a thickness of about 100μm or less. The first magnetic sheet 610, the second magnetic sheet 620 and / or the third magnetic sheet 700 can be implemented with various other materials. For example, the first magnetic sheet 610, the second magnetic sheet 620 and / or the third magnetic sheet 700 can be implemented as a nanosheet or a ferrite sheet.

[0159] According to various embodiments, at least two of the first magnetic sheet 610 , the second magnetic sheet 620 , and the third magnetic sheet 700 may be made of different materials.

[0160] According to various embodiments, the extension portion 623 may be implemented as a separate fourth magnetic sheet. The material forming the fourth magnetic sheet may be selected based on the frequency of the signal sent and / or received through the second region 820. For example, the fourth magnetic sheet may be implemented with a ferrite sheet having a relatively high dielectric constant and / or permeability at frequencies associated with NFC. For example, the fourth magnetic sheet may be made of a material having relatively high electromagnetic shielding properties at frequencies associated with NFC.

[0161] In some embodiments, reference Figure 7 and Figure 8 , the first electrical path 450 and / or the second electrical path 460 electrically connecting the first substrate assembly 341 and the second substrate assembly 342 may be omitted. In this case, the antenna structure 370 may further include a portion 830 extending from the second region 820 so as to be spaced apart from the rear plate 211 and the third magnetic sheet 700 is interposed between the rear plate 211 and the portion 830. According to an embodiment, the third magnetic sheet 700 may not be disposed at the rear plate 211, but may be disposed at the first surface 370a in the extended portion 830.

[0162] Fig. 9 is a cross-sectional view illustrating an example antenna structure 370 according to another embodiment.

[0163] According to various embodiments, Fig. 9 The setup structure shown can be applied to Figure 4 or Figure 7 The electronic device 200, according to an embodiment, Figure 4 or Figure 7 Some components can be omitted or can be used Fig. 9 According to various embodiments, according to its setting structure, Fig. 9 The coordinate axes can be Figure 4 or Figure 7The coordinate axis of the electronic device 200 is consistent with or can be consistent with Figure 4 or Figure 7 The coordinate axes of are formed differently. This can also be applied to Fig.10 , Fig.11 , Fig.12 , Fig.13 or Fig.14 .

[0164] According to an example embodiment, the antenna structure 370 may include Figure 4 The first region 810 of the first conductive pattern 510 and the Figure 4 The second region 820 of the second conductive pattern 520 may have a shape surrounding the first region 810 when viewed from above the rear plate 211. The first region 810 may transmit and / or receive a first signal in a first frequency band. The second region 820 may transmit and / or receive a second signal in a second frequency band different from the first frequency band. For example, the first signal may have a frequency associated with MST, and the second signal may have a frequency associated with NFC.

[0165] According to example embodiments, an antenna or an antenna system using the antenna structure 370 may include a third antenna structure in which, while the first magnetic sheet 910 is disposed at the first surface 370a of the antenna structure 370 and the second magnetic sheet 920 is disposed at the second surface 370b of the antenna structure 370, the first magnetic sheet 910 and the second magnetic sheet 920 partially overlap when viewed from above the rear plate 211. According to the third antenna structure, the first magnetic sheet 910 may be disposed closer to the third magnetic sheet 900 than the second magnetic sheet 920 in the -y-axis direction.

[0166] According to example embodiments, an antenna or an antenna system using the antenna structure 370 may include a fourth antenna structure in which the third magnetic sheet 900 faces the front plate 202 (see FIG. Figure 7 ) is disposed at a third surface 460a separated from the first surface 370a of the antenna structure 370, and is spaced apart from the second magnetic sheet 920 with the first magnetic sheet 910 interposed therebetween when viewed from above the rear plate 211. According to the fourth antenna structure, when viewed from above the rear plate, the first magnetic sheet 910 may include an end portion (e.g., Figure 4 The first portion 611 of the magnetic sheet 900 and the other end portion (eg, Figure 4 According to an example embodiment, the third surface 460a may be formed by the electrical path 460. According to the fourth antenna structure, the first magnetic sheet 910 may be disposed closer to the rear plate 211 than the second magnetic sheet 920 and the third magnetic sheet 900 in the -z-axis direction.

[0167] According to some embodiments, the first magnetic sheet 910 may not be disposed at the antenna structure 370 but may be disposed at the rear plate 211 (eg, the third surface 211 b ).

[0168] According to an embodiment, the first magnetic sheet 910 may be arranged not to overlap with the second region 820 when viewed from above the rear plate 211. For example, when a signal of a frequency related to NFC is transmitted and / or received through the second region 820, if there is the first magnetic sheet 910 between the rear plate 211 and the second region 820, the radiation performance through the second region 820 may be degraded due to the first magnetic sheet 910; therefore, the first magnetic sheet 910 may be arranged not to overlap with the second region 820 for NFC.

[0169] According to various embodiments, the second magnetic sheet 920 may extend to at least partially overlap the second region 820 when viewed from above the rear plate 211 (see reference numeral 923). The extended portion 923 of the second magnetic sheet 920 may shield noise. For example, Figure 7 The noise of the first substrate assembly 341 may be shielded by the extension portion 923 and thus be difficult to enter the second region 820 .

[0170] According to an embodiment, Fig. 9 The third antenna structure and the fourth antenna structure shown in the embodiment can perform the same Figure 8 The functions of the first antenna structure and the second antenna structure shown in the embodiment are substantially the same, so as to improve the radiation performance of the antenna structure 370. According to an example embodiment, when an electromagnetic field is formed by the antenna structure 370, electromagnetic coupling between the first magnetic sheet 910 and the second magnetic sheet 920 and electromagnetic coupling between the first magnetic sheet 910 and the third magnetic sheet 900 may occur. According to an embodiment, the third antenna structure and the fourth antenna structure may enable the electromagnetic energy emitted from the antenna structure 370 to be concentrated in a specific direction in space to improve the radiation performance. For example, the electromagnetic wave energy emitted from the antenna structure 370 may be concentrated in the direction (e.g., -z axis direction) substantially pointed to by the first surface 370a of the antenna structure 370 through the third antenna structure and the fourth antenna structure, or may be concentrated in the direction toward the rear plate 211, or may have directivity or directivity of sending or receiving waves. For example, by forming a preset boundary condition for the electromagnetic field from the antenna structure 370 via the third antenna structure and the fourth antenna structure, the electromagnetic wave energy may be guided in a specific direction.

[0171] According to an embodiment, the third magnetic sheet 900 may be provided to be electromagnetically coupled to the first magnetic sheet 910. When viewed from above the rear plate 211, a distance D2 between the third magnetic sheet 900 and the first magnetic sheet 910 may be formed such that electromagnetic coupling between the third magnetic sheet 900 and the first magnetic sheet 910 is possible. According to various embodiments, the distance D2 may be formed based on the wavelength of the radio wave emitted from the antenna structure 370 so that the third magnetic sheet 900 and the first magnetic sheet 910 are not electromagnetically isolated.

[0172] According to the embodiment, referring to Figure 5 and Fig. 9 , when viewed from above the rear plate 211, the distance D2 may be formed within a length that is approximately twice the first width W that the second pattern portion 513b between the first region 810 or the second boundary 540b of the first coil portion 513 and the battery 350 has in the y-axis direction.

For example, the second magnetic sheet 1020 and the third magnetic sheet 1000 may be arranged substantially parallel in the y-axis direction and may be spaced apart from each other. It may be difficult for two magnetic sheets 1020 and 1000 that are substantially parallel and arranged at an electromagnetic coupling distance to guide electromagnetic energy in a specific direction.
