Description

Technical Field

[0001] This disclosure relates to wearable devices including antennas. Background Technology

[0002] Wearable devices can be worn and used on a user's body. Wearable devices may include components for providing various functions. For example, a wearable device may include a substrate (e.g., a flexible printed circuit board) for providing an electrical connection between the components and an antenna for communicating with an external electronic device (e.g., the user's smartphone). Because wearable devices are used while worn on a user's body, they can have a size corresponding to the body part to which they are worn. For example, in the case where the wearable device is a ring-shaped device worn on a user's finger, the wearable device can have a size corresponding to the circumference of the finger.

[0025] Figure 1 This is a block diagram illustrating an electronic device 101 in a network environment 100 according to an embodiment.

[0026] Reference Figure 1 In network environment 100, electronic device 101 can communicate with electronic device 102 via a first network 198 (e.g., a short-range wireless communication network), or with at least one of electronic device 104 or server 108 via a second network 199 (e.g., a long-range wireless communication network). According to an embodiment, electronic device 101 can communicate with electronic device 104 via server 108. According to an embodiment, electronic device 101 may include a processor 120, memory 130, input module 150, sound output module 155, display module 160, audio module 170, sensor module 176, interface 177, connection terminal 178, haptic module 179, camera module 180, power management module 188, battery 189, communication module 190, subscriber identification module (SIM) 196, or antenna module 197. In some embodiments, at least one component (e.g., connection terminal 178) may be omitted from electronic device 101, or one or more other components may be added to electronic device 101. In some embodiments, some of the components (e.g., sensor module 176, camera module 180, or antenna module 197) may be implemented as a single component (e.g., display module 160).

[0027] Processor 120 can execute, for example, software (e.g., program 140) to control at least one other component (e.g., hardware or software component) of electronic device 101 coupled to processor 120, and can perform various data processing or calculations. According to embodiments, as at least part of data processing or calculation, processor 120 can store commands or data received from another component (e.g., sensor module 176 or communication module 190) in volatile memory 132, process the commands or data stored in volatile memory 132, and store the resulting data in non-volatile memory 134.

For example, when electronic device 101 includes a main processor 121 and an auxiliary processor 123, the auxiliary processor 123 may be adapted to consume less power than the main processor 121, or adapted to perform a specific function. The auxiliary processor 123 may be implemented separately from the main processor 121, or may be implemented as part of the main processor 121.

[0028] When the main processor 121 is inactive (e.g., in sleep mode), the auxiliary processor 123 (rather than the main processor 121) can control at least some of the functions or states associated with at least one component of the electronic device 101 (e.g., display module 160, sensor module 176, or communication module 190), or when the main processor 121 is active (e.g., running an application), the auxiliary processor 123 can work with the main processor 121 to control at least some of the functions or states associated with at least one component of the electronic device 101 (e.g., display module 160, sensor module 176, or communication module 190).

According to embodiments, the auxiliary processor 123 (e.g., a neural processing unit) may include hardware structures designated for artificial intelligence model processing.

[0031] Input module 150 can receive commands or data from outside electronic device 101 (e.g., a user) to be used by another component of electronic device 101 (e.g., processor 120). Input module 150 may include, for example, a microphone, mouse, keyboard, keys (e.g., buttons), or digital pen (e.g., stylus).

[0032] The audio output module 155 can output audio signals to the outside of the electronic device 101. The audio output module 155 may include, for example, a speaker or a receiver. The speaker can be used for general purposes, such as playing multimedia or playing records. The receiver can be used to receive incoming calls. According to an embodiment, the receiver can be implemented separately from the speaker or as part of the speaker.

[0033] Display module 160 can visually provide information to the outside of electronic device 101 (e.g., to a user). Display module 160 may include, for example, a display, a holographic device, or a projector, and control circuitry for controlling a respective one of the display, holographic device, and projector. According to an embodiment, display module 160 may include a touch sensor adapted to detect touch or a pressure sensor adapted to measure the intensity of the force caused by touch.

[0034] Audio module 170 can convert sound into electrical signals and vice versa. According to an embodiment, audio module 170 can obtain sound via input module 150, or output sound via sound output module 155 or headphones of an external electronic device (e.g., electronic device 102) that is directly (e.g., wired) connected to or wirelessly coupled to electronic device 101.

[0035] Sensor module 176 can detect the operating state of electronic device 101 (e.g., power or temperature) or the environmental state outside electronic device 101 (e.g., user state), and then generate an electrical signal or data value corresponding to the detected state. According to embodiments, sensor module 176 may include, for example, a gesture sensor, gyroscope sensor, atmospheric pressure sensor, magnetic sensor, accelerometer, grip sensor, proximity sensor, color sensor, infrared (IR) sensor, biometric sensor, temperature sensor, humidity sensor, or illuminance sensor.

[0036] Interface 177 may support one or more specified protocols used to enable direct (e.g., wired) or wireless coupling between electronic device 101 and external electronic device (e.g., electronic device 102). According to embodiments, interface 177 may include, for example, a High Definition Multimedia Interface (HDMI), a Universal Serial Bus (USB) interface, a Secure Digital Card (SD) interface, or an audio interface.

[0037] Connection terminal 178 may include a connector, through which electronic device 101 can be physically connected to an external electronic device (e.g., electronic device 102). According to embodiments, connection terminal 178 may include, for example, an HDMI connector, a USB connector, an SD card connector, or an audio connector (e.g., a headphone connector).

[0038] The haptic module 179 can convert electrical signals into mechanical stimuli (e.g., vibration or motion) or electrical stimuli that can be recognized by a user through his touch or kinesthesia. According to embodiments, the haptic module 179 may include, for example, a motor, a piezoelectric element, or an electrical stimulator.

[0039] Camera module 180 can capture still or moving images. According to an embodiment, camera module 180 may include one or more lenses, an image sensor, an image signal processor, or a flash.

[0040] The power management module 188 manages the power supply to the electronic device 101. According to an embodiment, the power management module 188 may be implemented as at least part of, for example, a power management integrated circuit (PMIC).

[0041] Battery 189 can power at least one component of electronic device 101. According to an embodiment, battery 189 may include, for example, a non-rechargeable primary battery, a rechargeable accumulator, or a fuel cell.

[0042] Communication module 190 can support the establishment of direct (e.g., wired) or wireless communication channels between electronic device 101 and external electronic devices (e.g., electronic device 102, electronic device 104, or server 108), and perform communication via the established communication channels. Communication module 190 may include one or more communication processors that can operate independently of processor 120 (e.g., application processor (AP)) and support direct (e.g., wired) or wireless communication. According to embodiments, communication module 190 may include wireless communication module 192 (e.g., cellular communication module, short-range wireless communication module, or Global Navigation Satellite System (GNSS) communication module) or wired communication module 194 (e.g., local area network (LAN) communication module or power line communication (PLC) module). 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™, Wi-Fi Direct, or Infrared Data Communication (IrDA)) or a second network 199 (e.g., a long-range communication network such as a traditional cellular network, 5G network, next-generation communication 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 as multiple components (e.g., multiple chips) that are separate from each other. The wireless communication module 192 can use subscriber information (e.g., International Mobile Subscriber Identity (IMSI)) stored in the subscriber identification module 196 to identify and verify the electronic device 101 in the communication network (e.g., the first network 198 or the second network 199).

[0043] Wireless communication module 192 can support 5G networks and next-generation communication technologies, such as New Radio (NR) access technologies, following 4G networks. NR access technologies can support enhanced mobile broadband (eMBB), massive machine-type communications (mMTC), or ultra-reliable and low-latency communications (URLLC). Wireless communication module 192 can support high-frequency bands (e.g., millimeter-wave bands) to achieve, for example, high data transmission rates. Wireless communication module 192 can support various technologies used to ensure performance in high-frequency bands, such as beamforming, massive MIMO, full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, or massive antennas. Wireless communication module 192 can support various requirements specified in electronic device 101, external electronic device (e.g., electronic device 104), or network system (e.g., second network 199). According to an embodiment, the wireless communication module 192 may support peak data rates (e.g., 20 Gbps or higher) for implementing eMBB, loss coverage (e.g., 164 dB or lower) for implementing mMTC, or U-plane latency (e.g., 0.5 ms or less for each of the downlink (DL) and uplink (UL), or 1 ms or less round trip) for implementing URLLC.

[0044] Antenna module 197 can transmit or receive signals or power to or from the outside of electronic device 101 (e.g., external electronic device). According to an embodiment, antenna module 197 may include an antenna comprising a radiating element formed of conductive material or conductive patterns formed in or on a substrate (e.g., a printed circuit board (PCB)). According to an embodiment, antenna module 197 may include multiple antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication scheme used in a communication network (such as a first network 198 or a second network 199) can be selected from the multiple antennas, for example by communication module 190 (e.g., wireless communication module 192). Signals or power can then be transmitted or received between communication module 190 and external electronic device via the selected at least one antenna. According to an embodiment, another component besides the radiating element (e.g., a radio frequency integrated circuit (RFIC)) may be additionally incorporated into antenna module 197.

[0045] According to various embodiments, antenna module 197 can form a millimeter-wave antenna module. According to embodiments, the millimeter-wave antenna module may include: a printed circuit board; an RFIC disposed on or adjacent to a first surface (e.g., bottom surface) of the printed circuit board and capable of supporting a specified high-frequency band (e.g., millimeter-wave band); and a plurality of antennas (e.g., array antennas) disposed on or adjacent to a second surface (e.g., top or side surface) of the printed circuit board and capable of transmitting or receiving signals in the specified high-frequency band.

[0046] At least some of the aforementioned components may be coupled to each other and communicate signals (e.g., commands or data) between them via a peripheral communication scheme (e.g., bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industrial processor interface (MIPI)).

[0047] According to an embodiment, commands or data can be sent or received between electronic device 101 and external electronic device 104 via server 108 connected to a second network 199. Each of electronic devices 102 or 104 can be a device of the same or different type as electronic device 101. According to an embodiment, all or some operations to be performed at electronic device 101 can be performed at one or more of external electronic devices 102, 104, or 108. For example, if electronic device 101 is required to perform a function or service automatically or in response to a request from a user or another device, instead of performing the function or service, or in addition to performing the function or service, electronic device 101 can request one or more external electronic devices to perform at least a portion of the function or service. Upon receiving the request, one or more external electronic devices can perform at least a portion of the requested function or service, or perform additional functions or services related to the request, and transmit the result of the performance to electronic device 101. Electronic device 101 can provide the result, with or without further processing, as at least part of a response to the request. For this purpose, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technologies can be used, for example. Electronic device 101 can use, for example, distributed computing or mobile edge computing to provide ultra-low latency services. In another embodiment, external electronic device 104 may include Internet of Things (IoT) devices. Server 108 may be an intelligent server using machine learning and / or neural networks. According to embodiments, external electronic device 104 or server 108 may be included in a second network 199. Electronic device 101 can be applied to intelligent services based on 5G communication technology or IoT-related technologies (e.g., smart homes, smart cities, smart cars, or healthcare).

[0048] Figure 2aA wearable device, according to an embodiment, is shown worn on a user's body. Figure 2b This is an exploded view of a wearable device according to an embodiment. Figure 2c This is a schematic block diagram of a wearable device according to an embodiment.

[0049] refer to Figure 2a Wearable devices according to embodiments (e.g., Figure 1 The wearable device 101 can be used while being worn on a user's body. For example, the wearable device 101 according to an embodiment may include a ring-shaped housing 220 that can be worn on a user's finger. The wearable device 101 including the ring-shaped housing 220 can be implemented as a ring-shaped device worn on a user's finger. In this disclosure, for ease of description, the wearable device 101 is described as a ring-shaped device, but is not limited thereto. For example, the wearable device 101 may include an earring device worn on a user's ear, a bracelet-shaped device worn on a user's arm, and / or a headband-shaped device worn on a user's head. The wearable device 101 can be used while being worn on a user's body. For example, the wearable device 101 may be configured to communicate with an external electronic device 300 (e.g., a smartphone) while being worn on a user's body.

[0050] For example, the housing 220 may form the exterior of the wearable device 101. For example, the size of the housing 220 may be determined based on the body portion of the wearer wearing the wearable device 101. Since the wearable device 101 is used while being worn on a user's body, the size of the housing 220 may be limited. For example, if the wearable device 101 is a ring-shaped device, the housing 220 may be limited to a size suitable for wearing on a finger.

[0051] refer to Figure 2b The wearable device 101 may include a housing 220 and a substrate 210.

[0052] For example, if the wearable device 101 is a ring-shaped device, the housing 220 may have a ring shape. For example, the housing 220 may include a first housing portion 221 and a second housing portion 222.

[0053] For example, the first housing portion 221 may be the part of the housing 220 that is exposed to the outside when the wearable device 101 is worn on the user's body. For example, the first housing portion 221 may form the outer surface of the annular housing 220.

[0054] For example, the second housing portion 222 may be the portion of housing 220 that is at least partially in contact with the user's body when the wearable device 101 is worn on the user's body. For example, the second housing portion 222 may be coupled to the first housing portion 221. For example, the second housing portion 222 may form the inner surface of the annular housing 220 by being inserted into the inner surface of the first housing portion 221. For example, a substrate 210 may be disposed between the first housing portion 221 and the second housing portion 222. The first housing portion 221 may be referred to as the outer portion in relation to forming the outer surface of housing 220. The second housing portion 222 may be referred to as the inner portion in relation to forming the inner surface of housing 220.

[0055] For example, the housing 220 can have a design that provides visual appeal. For example, the visual appeal of the wearable device 101 can be enhanced by the shape of the exposed first housing portion 221, the color of the first housing portion 221, and / or the pattern formed on the outer surface of the first housing portion 221. For example, because the wearable device 101 can be worn on a user's body, the wearable device 101 can provide aesthetic appeal by having a design that suits the user's preferences. Figure 2b The outer surface of the first housing portion 221 shown is depicted as having a generally smooth curved surface, but is not limited thereto.

[0056] The wearable device 101 according to an embodiment may include at least one electronic component 230 for implementing various functions. For example, the wearable device 101 may include a Global Positioning System (GPS) module for providing location information, and a module for providing communication with external electronic devices (e.g., Figure 2a The antenna (e.g., for communication with external electronic devices 300 (e.g., smartphones)) (e.g., Bluetooth communication) Figure 1 Antenna module 197), and sensors for collecting user health information and / or activity information (e.g., Figure 1 The sensor module 176), and the tactile module for providing mechanical stimulation (e.g., Figure 1 The tactile module 179) and / or the speaker for providing sound (e.g., Figure 1 The second housing portion 222 may include, but is not limited to, a sound output module 155. For example, at least one electronic component 230 may be located inside the housing 220 by being disposed on a substrate 210. For example, in the case where the wearable device 101 includes a sensor for measuring the user's heart rate (e.g., a photoplethysmography (PPG) sensor), the second housing portion 222 may include a substantially transparent portion that allows the sensor to acquire data about the user's heart rate and / or respiration.

[0057] For example, substrate 210 may include a flexible printed circuit board (FPCB). For example, flexible substrate 210 may be disposed within housing 220 by being deformable into a shape corresponding to the shape of housing 220. For example, in the case that wearable device 101 is a ring-shaped device, substrate 210 may be disposed within housing 220 by bending into a ring shape corresponding to the shape of housing 220.

[0058] For example, at least one electronic component 230 may be disposed on the substrate 210. For example, a sensor may be disposed on a first surface 210-1 of the substrate 210 facing the first housing portion 221 and / or a second surface 210-2 of the substrate 210 facing the second housing portion 222. For example, the substrate 210 may be electrically connected to a battery 189 for providing power to at least one electronic component 230. For example, at least one electronic component 230 may be electrically connected to the battery 189 via a conductive layer included in the substrate 210.

[0059] Reference Figure 2c The wearable device 101 according to an embodiment may include an antenna 260 and a means for communicating with external electronic devices (e.g., Figure 2a The wireless communication circuit (e.g., external electronic device 300) communicates with the external electronic device 300. Figure 1 The wireless communication module 192). For example, wearable device 101 may include processor 120, wireless communication circuitry 192, and antenna 260.

[0060] For example, processor 120 may include an application processor (AP) (e.g., Figure 1 The main processor 121) or communication processor (CP) (e.g., Figure 1 At least one of the auxiliary processors 123. For example, the wireless communication circuit 192 may include a radio frequency (RF) transceiver 192a and a radio frequency front end (RFFE) 192b.

[0061] For example, processor 120 can generate a baseband signal. Processor 120 can control RF transceiver 192a to process the generated baseband signal. Processor 120 can control RF transceiver 192a to transmit a signal through antenna 260. Processor 120 can control RF transceiver 192a to enable communication with external electronic devices (e.g., Figure 2a The external electronic device 300 transmits signals in the communication frequency band.

[0062] For example, RF transceiver 192a may be implemented as part of a single package or a single chip (e.g., an RFIC chip). RF transceiver 192a may include a digital-to-analog converter (DAC) for converting digital signals to analog signals. RF transceiver 192a may include a mixer and an oscillator (e.g., a local oscillator (LO)) for up-conversion. RF transceiver 192a can convert baseband signals generated by processor 120 into RF signals. RF transceiver 192a may include an analog-to-digital converter (ADC) for converting analog signals to digital signals. RF transceiver 192a may include a mixer and an oscillator for down-conversion. RF transceiver 192a can convert RF signals received from antenna 260 into baseband signals, such that the RF signals are processed by processor 120.

[0063] For example, RFFE 192b may include multiple components electrically connected between RF transceiver 192a and antenna 260. For example, RFFE 192b may include, but is not limited to, components such as couplers, power amplifiers (PA), low-noise amplifiers (LNA), switching circuitry, and / or duplexers.

[0064] For example, antenna 260 can be used to transmit and / or receive signals on a specified frequency band. For example, antenna 260 may include an antenna radiator, which is a physical component for radiating or receiving electromagnetic waves.

[0065] For example, an antenna radiator, as a physical component of an antenna that radiates electromagnetic waves into and / or receives electromagnetic waves from space, can transmit and / or receive signals via electromagnetic waves. The shape and performance of the antenna 260 can be determined based on the antenna radiator. For example, the frequency characteristics (e.g., resonant frequency) of the antenna 260 can be determined based on the size and shape of the antenna radiator. Because the antenna radiator has physical dimensions, a specific space may be required in which the antenna radiator can be housed. For example, because the wearable device 101 is limited to a size that is worn on a user's body, the internal space of the housing 220 for the antenna radiator may be insufficient.

[0066] The wearable device 101 according to an embodiment can use a substrate (e.g., Figure 2b At least a portion of the substrate 210 serves as an antenna radiator. For example, the substrate 210 may include a filled cut area (e.g., Figure 2b The first part separated by the filled cutting area 213 (e.g., Figure 2b The first part 211) and the second part (e.g., Figure 2b(Second part 212). For example, substrate 210 can operate as a dipole antenna based on the potential difference between the first part 211 and the second part 212. Since the wearable device 101 according to the embodiment uses at least a portion of substrate 210 as an antenna radiator, no separate arrangement space is required for the antenna radiator, thus simplifying the structure of the wearable device 101 and ensuring the internal space of the housing 220.

[0067] Figure 3a A substrate for a wearable device according to an embodiment is shown. Figure 3b The structure of the dipole antenna is shown. Figure 3c It shows that Figure 3a The substrate is set inside the housing.

[0068] Reference Figure 3a The substrate 210 may include a first portion 211, a second portion 212, and a fill-cut region 213. For example, the fill-cut region 213 may be located between the first portion 211 and the second portion 212.

[0069] For example, substrate 210 can provide wearable devices (e.g., Figure 2a Electrical connection of at least one electronic component 230 of the wearable device 101. For example, substrate 210 may include a plurality of conductive layers and a plurality of non-conductive layers alternately stacked with the plurality of conductive layers. For example, substrate 210 may provide electrical connection for at least one electronic component 230 by using wires and conductive vias formed on the conductive layers.

[0070] For example, the fill cut region 213 may be a region in which the ground layer has been removed. For example, a non-conductive layer may be exposed in the fill cut region 213. For example, the substrate 210 may include a first portion 211 and a second portion 212 separated by the fill cut region 213. For example, the fill cut region 213 may be disposed between the first portion 211 and the second portion 212. For example, based on the fill cut region 213, the first portion 211 and the second portion 212 may extend in opposite directions. For example, the first portion 211 may extend from the fill cut region 213 in a first direction D1. For example, the second portion 212 may extend from the fill cut region 213 in a second direction D2 opposite to the first direction D1.

[0071] For example, wireless communication circuitry 192 may be disposed on the first portion 211. For example, the second portion 212 may include a power supply point 214 electrically connected to wireless communication circuitry 192. For example, wireless communication circuitry 192 may be configured to connect to external electronic devices (e.g., [missing information]) using at least a portion of substrate 210 by powering the power supply point 214. Figure 2aThe device communicates with an external electronic device 300. For example, a portion of a feed path 215 for electrically connecting the wireless communication circuit 192 and the feed point 214 may be disposed in the fill cut region 213. For example, the wireless communication circuit 192 may provide an electrical signal to the feed point 214 via the feed path 215 disposed in the fill cut region 213. For example, the feed point 214 may be located at the end of the second portion 212 facing the first portion 211. For example, the second portion 212 may include a flange portion 216 formed at the end and including the feed point 214. For example, the flange portion 216 may be electrically connected to the feed path 215 by protruding from the second portion 212 into the fill cut region 213. The flange portion 216 connected to the second portion 212 may operate as part of an antenna radiator. The flange portion 216 may also be used for impedance matching to adjust the impedance of the antenna radiator. For example, flange 216 may be electrically connected to antenna switching circuit 217, which is used to adjust the parameter values ​​(e.g., inductance and / or capacitance) of passive components (e.g., inductors and / or capacitors) electrically connected to at least a portion of the substrate 210 that serves as an antenna radiator. For example, a processor (e.g., Figure 2c The processor 120 can be configured to control the antenna switching circuit 217. For example, the antenna switching circuit 271 can operate as a tunable matching circuit by including a switching circuit and at least one component.

[0072] For example, when an electrical signal is supplied to feed point 214, a radiated current can flow along at least a portion of substrate 210. An electromagnetic field can be formed around substrate 210 by the radiated current. When an electromagnetic wave radiates through at least a portion of substrate 210 via the electromagnetic field, at least a portion of substrate 210 can be used as an antenna radiator. For example, based on the electrical signal supplied to feed point 214 via fill cut region 213, at least a portion of substrate 210 can operate as a dipole antenna including a first portion 211 and a second portion 212, wherein the first portion 211 and the second portion 212 have substantially the same electrical length relative to the feed location. For example, at least a portion of substrate 210 can operate as an antenna (e.g., a dipole antenna) based on the potential difference between the first portion 211 and the second portion 212.

[0073] Figure 3b The basic structure of the dipole antenna 301 is shown. (Refer to...) Figure 3bThe dipole antenna 301 may include two conductive electrodes (e.g., a first conductive electrode 310 and a second conductive electrode 320) connected to a feed line (e.g., a coaxial cable) 330. For example, when a positive feed is provided to the first conductive electrode 310 and a negative feed is provided to the second conductive electrode 320, a current can flow through the potential difference between the first conductive electrode 310 and the second conductive electrode 320. The flow of current can induce electric and magnetic fields perpendicular to each other. When the electric and magnetic fields vibrate through an alternating current whose direction changes over time, electromagnetic waves can be generated from the dipole antenna 301. The first conductive electrode 310 and the second conductive electrode 320 forming the dipole antenna 301 may be separated by an insulator 340 between the first conductive electrode 310 and the second conductive electrode 320. For example, when the wavelength corresponding to the resonant frequency of the signal transmitted and / or received by the dipole antenna 301 is w, the electrical length L4 of the first conductive electrode 310 and the electrical length L5 of the second conductive electrode 320 may be approximately w / 4, and the total electrical length L6 of the conductive electrodes may be approximately w / 2. In this disclosure, electrical length may be referred to as the length of an antenna radiator capable of radiating or receiving electromagnetic waves through a formed electromagnetic field.

[0074] Refer again Figure 3a The fill cut region 213 can be located substantially at the center of the substrate 210. For example, the electrical length L1 of the first portion 211 and the electrical length L2 of the second portion 212 separated by the fill cut region 213 can be substantially the same. For example, the electrical length L1 of the first portion 211 can correspond to the electrical length L2 of the second portion 212. However, it is not limited to this. The electrical length L1 of the first portion 211 can be different from the electrical length L2 of the second portion 212.

[0075] For example, substrate 210 can be formed into a dipole antenna. For example, the first portion 211 can correspond to the first conductive electrode of the dipole antenna (e.g., Figure 3b The first conductive electrode 310). For example, the second part 212 may correspond to the second conductive electrode of the dipole antenna (e.g., Figure 3b The second conductive electrode 320). For example, the filled cut region 213 separating the first portion 211 and the second portion 212 can correspond to the insulator separating the first conductive electrode 310 and the second conductive electrode 320 (e.g., Figure 3b(Insulator 340). For example, at least a portion of the substrate 210 may be configured to transmit and / or receive signals at a resonant frequency based on the electrical length L of the substrate 210. For example, when the wavelength corresponding to the resonant frequency of the signal transmitted and / or received by an antenna using at least a portion of the substrate 210 as an antenna radiator is w, the electrical length L1 of the first portion 211 and the electrical length L2 of the second portion 212 may be approximately w / 4, and the total electrical length L of the substrate 210 may be approximately w / 2. For example, when the frequency of the signal transmitted and / or received by the antenna is approximately 2.4 GHz, the wavelength may be approximately 120 mm, and the electrical length L1 of the first portion 211 and the electrical length L2 of the second portion 212 may be approximately 30 mm. However, this is not a limitation.

[0076] For example, wearable device 101 may include a battery 189 electrically connected to substrate 210. For example, the battery 189 connected to substrate 210 may be configured to provide power for the operation of at least one electronic component 230 disposed on substrate 210. For example, battery 189 may form at least a portion of an antenna radiator. For example, when an electrical signal is provided to feed point 214, at least a portion of battery 189 may function together with at least a portion of substrate 210 as an antenna radiator (e.g., Figure 3b The second conductive electrode 320 operates. For example, the battery 189 may include a conductive housing in which a battery cell is housed. When an electrical signal is supplied to the feed point 214, a radiated current may flow along at least a portion of the substrate 210 (e.g., the second portion 212) and at least a portion of the conductive housing of the battery 189. Through the radiated current, at least a portion of the conductive housing of the battery 189 may operate as an antenna radiator together with at least a portion of the second portion 212. For example, the second portion 212 and the battery 189 may form a second conductive electrode (e.g., Figure 3b (Second conductive electrode 320). For example, the electrical length L2 of the second portion 212 can be referred to as the electrical length L3 including the battery 189. For example, the electrical length L1 of the first portion 211 can correspond to the electrical length L2 including the electrical length L3 of the battery 189.

[0077] Reference Figure 3c The substrate 210 can be disposed in the housing 220 surrounding the substrate 210 in a state of at least partial bending. For example, when the housing 220 is annular, the substrate 210 can be bent to have a shape corresponding to the shape of the housing 220. For example, when the battery 189 is connected to the substrate 210, the battery 189 can be at least partially bent to correspond to the shape of the substrate 210.

[0078] As described above, at least a portion of the substrate 210 can be used as an antenna radiator. The first portion 211 can form a first conductive electrode (e.g., Figure 3b At least a portion of the first conductive electrode 310), and the second portion 212 can form a second conductive electrode (e.g., Figure 3b At least a portion of the second conductive electrode 320. When the battery 189 is connected to the second portion 212, the battery 189 can form the second conductive electrode 320 together with the second portion 212.

[0079] For example, when the substrate 210 is bent to correspond to a ring shape, in order to make at least a portion of the substrate 210 serve as an antenna (e.g., a dipole antenna), the end 310a of the first conductive electrode 310 may be spaced apart from the end 320a of the second conductive electrode 320. For example, when the substrate 210 is bent into a ring shape within the housing 220, the end 210a of the substrate 210 may be spaced apart from another end 210b of the substrate 210 opposite to the end 210a. For example, when the battery 189 is connected to the second portion 212, the end 210a may be spaced apart from the end 189a of the battery 189. The antenna (e.g., a dipole antenna) may be formed by the first conductive electrode 310 spaced apart from the second conductive electrode 320.

[0080] For example, wireless communication circuits (e.g., Figure 2c The wireless communication circuit 192 can be configured to communicate with external electronic devices (e.g., using at least part of a substrate 210 and at least one electronic component 230). Figure 2a The external electronic device 300 communicates with the substrate 210. For example, at least one electronic component 230 disposed on the substrate 210 may be used together with the substrate 210 as an antenna radiator. For example, at least one electronic component 230 may include a conductive component (e.g., a metal component). For example, the conductive component may be electrically connected to at least one substrate 210. For example, when a wireless communication circuit (e.g., Figure 2c The wireless communication circuit 192) feeds power to the substrate 210 at the point (e.g., Figure 3a When fed at feed point 214, a radiated current can be formed along at least a portion of the substrate 210 and at least a portion of the conductive component of at least one electronic component 230, thereby generating an electromagnetic field. When electromagnetic waves are radiated through the electromagnetic field, the wireless communication circuit 192 can communicate with external electronic devices (e.g., Figure 2a External electronic devices (300) communicate.

[0081] For example, the size of substrate 210 may increase if a separate antenna radiator (e.g., a conductive pattern) is included in substrate 210. Space may be required for the physical connection members, such as C-clamps or conductive porons, when a connection member for transmitting electrical signals between the antenna radiator and wireless communication circuit 192 is included. Since the wearable device 101 according to the embodiment can use substrate 210 and / or at least one electronic component 230 as an antenna radiator, a separate antenna radiator (e.g., a conductive pattern) can be omitted within housing 220. The internal space of housing 220 may be narrower due to the size of wearable device 101 for wearing on a user's body. Since space for a separate antenna radiator can be omitted in wearable device 101 according to the embodiment, space can be ensured for another component (e.g., at least one electronic component 230). For example, since substrate 210 can operate as a dipole antenna through a filled cut region 213 formed in substrate 210, the connection member for transmitting electrical signals between the antenna radiator and wireless communication circuit 192 can be omitted. Wearable device 101, which uses at least a portion of substrate 210 as an antenna radiator according to an embodiment, can ensure internal space of housing 220 and reduce manufacturing costs.

[0082] Figure 4a A wire disposed in a filled cut area within a substrate according to an embodiment is shown. Figure 4b This is a graph showing the radiation efficiency of the antenna in a wearable device.

[0083] Reference Figure 4a At least one conductor 250 may be disposed in the filled cut area 213. For example, at least one conductor 250 may include a conductor connection portion 410, which includes a first conductor 251 and / or a second conductor 252. For example, at least one conductor 250 may extend from the first portion 211 through the filled cut area 213 to the second portion 212.

[0084] For example, at least one wire 250 may be distinguished from the feed path 215, which is used to electrically connect the wireless communication circuit 192 disposed in the first portion 211 and the feed point 214 in the flange portion 216. For example, at least one wire 250 may include a wire for connecting the wireless communication circuit 192 disposed in the first portion 211 and the feed point 214 in the flange portion 216. Figure 2c A first wire 251 for transmitting signals between the processor 120 and at least one electronic component 230, and a second wire 252 for electrically connecting the ground plane in the first part 211 and the ground plane in the second part 212.

[0085] For example, processor 120 may be disposed on first portion 211. For example, first wire 251 may extend from processor 120 through fill cut region 213 to at least one electronic component 230 disposed in second portion 212. For example, at least one electronic component 230 disposed on second portion 212 may be electrically connected to processor 120 via first wire 251. For example, in the case where at least one electronic component 230 includes a sensor, control signals for controlling the operation of the sensor may be transmitted from processor 120 to the sensor via first wire 251. For example, sensing data measured by the sensor may be transmitted from sensor to processor 120 via first wire 251.

[0086] For example, substrate 210 may include a ground plane electrically connected to the ground of wearable device 101. For example, a second conductor 252 may extend from the ground plane in the first portion 211 through the fill cut region 213 to the ground plane in the second portion 212. For example, the second conductor 252 may be configured to shield against crosstalk that causes noise between signal lines in the fill cut region 213. For example, the second conductor 252 may be configured to shield against electromagnetic interference between electrical signals (e.g., control signals and sensing data) transmitted through the first conductor 251 and another signal line (e.g., feed path 215 and / or another conductor). For example, the second conductor 252 may surround the first conductor 251 in the fill cut region 213. For example, the second conductor 252 may include two wires positioned such that the first conductor 251 is interposed within the fill cut region 213. For example, when an electrical signal flows along the first conductor 251, the induced signal component caused by the electrical signal may discharge to ground through the second conductor 252 electrically connected to the ground plane of substrate 210.

[0087] For example, wearable device 101 may include a connection member 270 located in the filled cut region 213 and electrically connected to at least one conductor 250. For example, it may be necessary for the conductors in substrate 210 to be matched with a reference impedance (e.g., 50 ohms) for impedance matching. For example, connection member 270 may include passive elements (e.g., inductors and / or capacitors) having specified parameter values ​​(e.g., inductance and / or capacitance). For example, connection member 270 may be an inductor with a specified inductance value, such that at least one conductor 250 has a reference impedance.

[0088] In an embodiment, the wire connection portion 410 may be one or more. For example, the wire connection portion 410 may include a first wire connection portion 411 disposed on one side of the feed path 215 and a second wire connection portion 412 disposed on the other side of the feed path 215. However, it is not limited thereto. The wire connection portion 410 may include only one wire connection portion (e.g., the first wire connection portion 411), or it may include two or more wire connection portions, and the number of wires (e.g., the first wire 251 and / or the second wire 252) is not limited.

[0089] For example, even when the connecting member 270 is located within the filled cut area 213, the antenna of the wearable device 101 can maintain substantially the same performance. (Refer to...) Figure 4b Graph 400 shows the distribution based on whether at least one line is included (e.g., Figure 4a At least one conductor 250) and connecting components (e.g., Figure 4a The change in the radiation efficiency of the antenna (connecting member 270). The x-axis of graph 400 is frequency (unit: gigahertz (GHz)) and the y-axis of graph 400 is radiation efficiency (unit: decibel (dB)).

[0090] Figure 4b The first graph 401 shows when wearable devices (e.g., Figure 4a When the wearable device 101 does not include at least one wire 250 and a connecting member 270, it includes a substrate (e.g., Figure 4a The radiation efficiency of at least a portion of the antenna of the substrate 210 according to the frequency. Figure 4b The second curve 402 shows when the wearable device 101 includes a fill cut area (e.g., Figure 4a The radiation efficiency of the antenna according to frequency when filling at least one conductor 250 and connecting member 270 in the cut area 213). When comparing the first curve 401 and the second curve 402, the first curve 401 and the second curve 402 can be substantially the same in the frequency range between about 2.35 GHz and about 2.45 GHz. For example, in the case where the target frequency to be transmitted and / or received by the antenna is about 2.4 GHz, the radiation efficiency indicated by the first curve 401 for the frequency of about 2.4 GHz can be substantially the same as the radiation efficiency indicated by the second curve 402. Refer to Figure 4b Even when at least one conductor 250 and connecting member 270 are located in the filled cut area 213, the radiation efficiency of the antenna can be maintained.

[0091] Figure 5a The distribution of current formed in the substrate of a wearable device according to an embodiment is illustrated schematically. Figure 5b An electromagnetic field formed in a wearable device according to an embodiment is illustrated schematically. Figure 5c This is a graph showing the radiation efficiency of the antenna of the electronic device according to an embodiment.

[0092] Reference Figure 5a When at least a portion of substrate 210 is used as an antenna radiator, radiated current can flow along at least a portion of substrate 210. For example, radiated current can flow at least partially along a grounded region included in substrate 210 and / or a region including a conductive member (e.g., battery 189) electrically connected to substrate 210. For example, when from a wireless communication circuit (e.g., Figure 2c Wireless communication circuit 192) to the feed point (e.g., Figure 3a When an electrical signal is provided at the feed point 214, a radiated current can flow along at least a portion of the substrate 210. The flow of the radiated current can induce an electromagnetic field formed on at least a portion of the substrate 210. Through the vibration of the electromagnetic field, electromagnetic waves can be radiated from at least a portion of the substrate 210 into space.

[0093] like Figure 5a As shown, the radiated current can be formed along at least a portion of the substrate 210 (or at least a portion of the substrate 210 and the battery 189). For example, if at least a portion of the substrate 210 is not used as an antenna radiator and a separate antenna radiator for radiating and / or receiving electromagnetic waves is provided in the substrate 210, the radiated current can be concentrated on the separately provided antenna radiator.

[0094] In wearable devices according to embodiments (e.g., Figure 2a In the case of a wearable device 101, since at least a portion of the substrate 210 serves as an antenna radiator, a radiating current can be formed along at least a portion of the substrate 210. For example, since it is provided in the housing (e.g., Figure 2a The shape of the substrate 210 inside the housing 220 is bent to correspond to the shape of the housing 220, so that radiative current can be formed substantially uniformly over the entire area of ​​the housing 220.

[0095] Reference Figure 5b An electromagnetic field formed by an antenna including at least a portion of the substrate 210 can be formed along the entire area of ​​the housing 220. Figure 5b Figure 501 shows the electromagnetic field formed around the annular housing 220 when viewed from the front at the opening 223. Figure 5b Figure 502 shows the electromagnetic field formed around the annular housing 220 when viewed from the side.

[0096] Reference Figure 5bSince the radiation current can be formed substantially uniformly over the entire area of ​​the housing 220, the electromagnetic field used to radiate electromagnetic waves can also be formed substantially uniformly over the entire area of ​​the housing 220.

[0097] For example, if at least a portion of the substrate 210 is not used as an antenna radiator and a separate antenna radiator is provided in the substrate 210, the electromagnetic field generated by the antenna can be strongly formed in the area of ​​the housing 220 where the antenna radiator is provided because the radiated current is concentrated on the separately provided antenna radiator, and can be formed weaker as the distance from the antenna radiator increases. When the electromagnetic field is concentrated only in a specific area of ​​the housing 220, the communication performance of the wearable device 101 may degrade. For example, if the wearable device 101 is a ring-shaped device, it can be worn on the user's finger. For example, if the wearable device 101 is worn on the middle finger, a portion of the housing 220 may be covered by the index finger and / or ring finger. For example, if the wearable device 101 is rotated while worn on the middle finger and the area of ​​the housing 220 where the antenna radiator is provided is covered by the index finger and / or ring finger, the electromagnetic field may be blocked by the index finger or ring finger, and therefore the antenna performance may degrade.

[0098] Since the wearable device 101 according to the embodiment uses at least a portion of the substrate 210 as an antenna radiator, such as Figure 5b As shown, an electromagnetic field can therefore be formed substantially uniformly over the entire area of ​​housing 220. The communication performance of the wearable device 101 according to the embodiment can be improved by forming an electromagnetic field substantially uniformly over the entire area of ​​housing 220. For example, when the wearable device 101 is worn on the middle finger, even when a portion of housing 220 is covered by the index and / or ring fingers, signals can be transmitted and / or received by the electromagnetic field formed on the exposed portion of housing 220, thus maintaining the antenna performance substantially constant.

[0099] Figure 5c Graph 500 shows the curves according to the substrate (e.g., Figure 5a The radiation efficiency of the antenna at at least a portion of the substrate 210. The x-axis of the graph 500 is frequency (in gigahertz (GHz)) and the y-axis of the graph 500 is radiation efficiency (in decibels (dB)).

[0100] refer to Figure 5c Figure 500 illustrates the high radiative efficiency in the frequency range between approximately 2.4 GHz and approximately 3 GHz. For example, in wearable devices (e.g., Figure 5b The wearable device 101) uses a frequency of approximately 2.4 GHz to communicate with external electronic devices (e.g., Figure 2aWhen paired with an external electronic device 300 (e.g., a smartphone), an antenna including at least a portion of the substrate 210 can be used as an antenna for pairing. For example, the antenna can be used as an antenna for transmitting and / or receiving Bluetooth signals and / or WiFi signals, but is not limited thereto.

[0101] Figure 6a , Figure 6b and Figure 6c This is a graph showing the radiation efficiency of the antenna based on the wearing status of the wearable device.

[0102] Figure 6a , Figure 6b and Figure 6c This is a graph used to compare the communication performance of wearable device 101 according to an embodiment and wearable device according to a comparative example. As described above, wearable device 101 according to an embodiment may include a substrate (e.g., Figure 2b A wearable device that uses at least a portion of the substrate 210 as an antenna (e.g., a first antenna) as an antenna radiator. The wearable device according to the comparative example may refer to a wearable device that includes an antenna (e.g., a second antenna) comprising a separate antenna radiator disposed in a portion of the substrate 210. Apart from having a separate antenna radiator disposed on the substrate 210, the wearable device according to the comparative example may be substantially the same as the wearable device 101 according to the embodiment. The x-axis of graphs 601, 602, and 603 represents frequency (in gigahertz (GHz)), and the y-axis of graphs 601, 602, and 603 represents radiation efficiency (in decibels (dB)).

[0103] See Figure 6a , Figure 6a 600a illustrates a user's finger as seen from above in a first wearing state, wherein the wearable device 101 according to an embodiment or the wearable device according to a comparative example is worn on the user's finger. For example, Figure 6a Figure 600b shows the user's fingers viewed from the front in the first wearing state. For example, in the first wearing state, the position of the power supply point 214 can be aligned with the upper part of the housing 220 (e.g., the +y direction portion of the housing 220).

[0104] Figure 6a Graph 601 shows the radiation efficiency of the antenna of the wearable device in the first wearing state. First graph 601-1 shows the radiation efficiency of the first antenna of the wearable device 101 according to an embodiment in the first wearing state. Second graph 601-2 shows the radiation efficiency of the second antenna of the wearable device according to a comparative example in the first wearing state.

[0105] When comparing the first curve 601-1 and the second curve 602-2, the radiation efficiency of the first antenna and the second antenna can be similar. For example, for a frequency of approximately 2.4 GHz, the radiation efficiency of the first antenna can be substantially the same as that of the second antenna. For example, when the frequency of the signals transmitted and / or received through the first and second antennas is approximately 2.4 GHz, the communication performance of the wearable device 101 including the first antenna according to the embodiment can be substantially similar to the communication performance of the wearable device including the second antenna according to the comparative example. As described above, since the wearable device 101 according to the embodiment uses at least a portion of the substrate 210 as an antenna radiator, the internal space of the housing 220 can be ensured. The wearable device 101 according to the embodiment can have substantially the same communication performance as the wearable device according to the comparative example while ensuring the internal space of the housing 220.

[0106] refer to Figure 6b In the case where the wearable device 101 according to the embodiment or the wearable device according to the comparative example is worn on the user's middle finger, a portion of the housing 220 can be covered by the index and ring fingers. For example, Figure 6b Figure 600c shows a user's hand as seen from above in a second wearing state, wherein the wearable device 101 according to an embodiment or the wearable device according to a comparative example is worn on the user's middle finger and partially covered by the index and ring fingers. For example, Figure 6b The 600d figure shows the user's hand viewed from the front in the second wearing state. For example, in the second wearing state, the position of the power supply point 214 can be aligned with the upper part of the housing 220 (e.g., the +y direction portion of the housing 220).

[0107] Figure 6b Graph 602 shows the radiation efficiency of the antenna of the wearable device in the second wearing state. Graph 602-1 shows the radiation efficiency of the first antenna of the wearable device 101 according to the embodiment in the second wearing state. Graph 602-2 shows the radiation efficiency of the second antenna of the wearable device according to the comparative example in the second wearing state.

[0108] When comparing the third curve 602-1 and the fourth curve 602-2, in the frequency range between approximately 2.35 GHz and approximately 2.45 GHz, the radiative efficiency of the first antenna can be higher than that of the second antenna. For example, at a frequency of approximately 2.4 GHz, the radiative efficiency of the first antenna can be approximately 1.6 dB higher than that of the second antenna. At a frequency of approximately 2.4 GHz, the radiative efficiency of the first antenna can be approximately -14.4 dB, and the radiative efficiency of the second antenna can be approximately -16 dB.

[0109] For example, when the frequency of the signals transmitted and / or received via the first and second antennas is approximately 2.4 GHz, the communication performance of the wearable device 101 including the first antenna according to the embodiment may be superior to that of the wearable device including the second antenna according to the comparative example. For example, in the case of the electronic device according to the embodiment, since the electromagnetic field is formed substantially uniformly over the entire area of ​​the housing 220, the finger (e.g., Figure 6b Interference from the index finger and / or ring finger touching the housing 220 can be minimal. For example, in the case of the wearable device according to the comparative example, since the electromagnetic field is essentially concentrated on the upper part of the housing 220 aligned with the antenna radiator (e.g., the +y direction portion of the housing 220), the antenna's radiation efficiency may be reduced due to interference from the finger touching the housing 220. When the wearable device is used while worn on the body, since contact between the housing 220 and the user's body may occur frequently, the communication performance of the wearable device 101 according to the embodiment may be better than that of the wearable device according to the comparative example.

[0110] refer to Figure 6c The wearable device can rotate while worn on a finger. For example, when the wearable device 101 rotates, the position of the power supply point 214 can be aligned with the side surface of the housing 220 (e.g., the +x direction portion or the -x direction portion of the housing 220). For example, when the wearable device 101 is worn on the middle finger and the position of the power supply point 214 is aligned with the side surface of the housing 220, the power supply point 214 can face the index finger or ring finger. Figure 6c Figure 600e shows a user's hand as seen from above in a third wearing state, wherein the wearable device 101 according to an embodiment or the wearable device according to a comparative example is worn on the user's middle finger, and the power supply point 214 is partially covered by the index and ring fingers. For example, Figure 6c The 600f figure shows the user's hand viewed from the front in the third wearing state. For example, in the third wearing state, the position of the power supply point 214 can be aligned with the side surface of the housing 220 (e.g., the +x direction portion or the -x direction portion of the housing 220).

[0111] Figure 6c Graph 603 shows the radiation efficiency of the antenna of the wearable device. Graph 603-1 shows the radiation efficiency of the first antenna of the wearable device 101 according to an embodiment in a third wearing state. Graph 603-2 shows the radiation efficiency of the second antenna of the wearable device according to a comparative example in a third wearing state.

[0112] When comparing the fifth curve (603-1) and the sixth curve (603-2), the radiative efficiency of the first antenna can be higher than that of the second antenna in the frequency range between approximately 2.36 GHz and approximately 2.45 GHz. For example, at a frequency of approximately 2.4 GHz, the radiative efficiency of the first antenna can be approximately 0.7 dB higher than that of the second antenna. At a frequency of approximately 2.4 GHz, the radiative efficiency of the first antenna can be approximately -17.9 dB, and the radiative efficiency of the second antenna can be approximately -18.6 dB.

[0113] For example, when the frequency of the signals transmitted and / or received via the first and second antennas is approximately 2.4 GHz, the communication performance of the wearable device 101 including the first antenna according to the embodiment can be better than that of the wearable device including the second antenna according to the comparative example. For example, in the case of the electronic device according to the embodiment, since the electromagnetic field is formed substantially uniformly over the entire area of ​​the housing 220, even when the position of the feed point 214 faces the side surface of the housing 220, the finger touching the housing 220 (e.g., Figure 6b Interference from the index and / or ring fingers can also be minimal. For example, in the case of the wearable device according to the comparative example, since the electromagnetic field is essentially concentrated on the side surface of the housing 220 aligned with the antenna radiator, the radiation efficiency of the antenna may be reduced due to interference from fingers touching the housing 220. When the wearable device is used while worn on the body, the communication performance of the wearable device 101 according to the embodiment may be better than that of the wearable device according to the comparative example because rotation of the wearable device 101 may occur frequently.

[0114] like Figure 6a , Figure 6b and Figure 6c As shown, the wearable device 101, which uses at least a portion of the substrate 210 as an antenna radiator, can have substantially the same communication performance as or better than that of the wearable device according to the comparative example. The wearable device 101 according to the embodiment can ensure internal space of the housing 220 and can have improved communication performance.

[0115] Figure 7a The structure of the housing of a wearable device according to an embodiment is shown. Figure 7b It shows the basis Figure 7a The diagram shows the radiation efficiency of the antenna with the structure of the housing shown. Figure 7c An exemplary non-conductive portion is shown.

[0116] For example, the housing 220 may be formed of non-conductive and / or conductive materials. For example, if the housing 220 is formed of a non-conductive material, the housing 220 may include, but is not limited to, plastics, ceramics, synthetic fibers and / or rubber. For example, if the housing 220 is formed of a conductive material, the housing 220 may include metals such as gold, silver and platinum and / or silicon, but is not limited to these.

[0117] Reference Figure 7a The housing 220 may optionally include a segment structure. A segment structure can refer to a structure in which a portion of the housing 220 is formed of a material distinguishable from the rest of the housing 220, thereby having physical and / or chemical properties distinguishable from the rest of the housing. For example, the housing 220 may include a conductive portion 710 comprising a conductive material and / or a non-conductive portion 720 comprising a non-conductive material.

[0118] Figure 7a Figure 700a shows a wearable device 101 having a housing 220 consisting only of non-conductive material. For example, the housing 220 may consist only of a non-conductive portion 720. For example, in the case where the housing 220 is formed only of non-conductive material, electromagnetic waves radiated from at least a portion of the substrate 210 inside the housing 220 can easily pass through the housing 220 and be radiated. For example, the housing 220 may not include a segmented structure.

[0119] Figure 7a Figure 700b illustrates a wearable device 101 having a housing 220 comprising only conductive material. For example, the housing 220 may comprise only conductive portions 710. For example, in the case where the housing 220 is formed using only conductive material, electromagnetic waves radiated from at least a portion of the substrate 210 inside the housing 220 may be shielded by the conductive material included in the housing 220, and thus may be difficult to radiate. For example, the housing 220 may not include segmented structures.

[0120] Figure 7a Models 700c, 700d, and 700e illustrate a wearable device 101 having a housing 220 comprising conductive and non-conductive materials. For example, the housing 220 may include a conductive portion 710 and a non-conductive portion 720. Figure 7a Figure 700c shows a wearable device 101, which includes a first non-conductive portion 721 formed in a first region of a housing 220, the first non-conductive portion 721 being at least partially connected to a power supply point (e.g., Figure 3a Align the feed point 214. Figure 7a700d shows a wearable device 101, which includes a second non-conductive portion 722 located in a second region of a housing 220, the second region being at least partially aligned with an end of a substrate 210 (e.g., end 210a and / or another end 210b). Figure 7a The 700e shows a wearable device 101, which includes a first non-conductive portion 721 formed in a first region and a second non-conductive portion 722 formed in a second region.

[0121] Reference Figure 7b The radiation efficiency of the antenna can be based on the housing (e.g., curve 700). Figure 7a The material and structure of the shell 220 vary. The x-axis of graph 700 is frequency (in gigahertz (GHz)) and the y-axis of graph 700 is radiation efficiency (in decibels (dB)).

[0122] Figure 7b The first curve 701 shows a curve that includes only non-conductive portions (e.g., Figure 7a The non-conductive portion 720) of the housing 220 of the wearable device (e.g., Figure 7a Wearable devices 101 (e.g., Figure 7a The radiation efficiency of the antenna in 700a). Figure 7b The second curve, 702, shows a section that includes only conductive portions (e.g., Figure 7a The wearable device 101 (e.g., the conductive part 710) of the housing 220 of the conductive part 710) Figure 7a The radiation efficiency of the antenna in 700b). Figure 7b The third curve 703 shows a portion including a conductive portion 710 and a first non-conductive portion (e.g., Figure 7a The wearable device 101 (e.g., the first non-conductive portion 721) Figure 7a The radiation efficiency of the antenna in the 700c). Figure 7b The fourth curve 704 shows a portion including a conductive portion 710 and a second non-conductive portion (e.g., Figure 7a The wearable device 101 (e.g., the second non-conductive portion 722) is a wearable device 101 (e.g., Figure 7a The radiation efficiency of the antenna in 700d). Figure 7b The fifth graph 705 illustrates a wearable device 101 including a conductive portion 710, a first non-conductive portion 721, and a second non-conductive portion 722 (e.g., Figure 7a The radiation efficiency of the antenna in the 700e).

[0123] Reference Figure 7bThe second curve 702 has the lowest radiation efficiency in the frequency range between approximately 2.3 GHz and approximately 2.5 GHz. When the housing 220 includes only the conductive portion 710, electromagnetic waves radiated from at least a portion of the substrate 210 inside the housing 220 are shielded by the conductive portion 710, making radiation difficult and thus potentially reducing the antenna's radiation efficiency.

[0124] The fourth curve, Figure 704, shows the highest radiative efficiency in the frequency range between approximately 2.3 GHz and approximately 2.5 GHz. For example, when an electrical signal is fed to the feed point (e.g., Figure 7a When the feed point 214 is reached, the strongest radiation current can be formed at the feed point 214, and the radiation current can also be generated at the end of the substrate 210 furthest from the feed point 214 (e.g., at the feed point 214). Figure 7a The electromagnetic field is most strongly formed at one end 210a and / or the other end 210b. Since electromagnetic waves can be transmitted to the outside of the housing 220 through the second non-conductive portion 722 aligned with the end where the electromagnetic field of the substrate 210 is most strongly formed, it can have the highest radiation efficiency.

[0125] The first curve 701 and the fifth curve 705 have substantially the same radiative efficiency in the frequency range between approximately 2.3 GHz and approximately 2.5 GHz. In the frequency range between approximately 2.3 GHz and approximately 2.5 GHz, the third curve 703 may have a lower radiative efficiency than the fourth curve 704 but a higher radiative efficiency than the first and fifth curves. Except for the second curve 702, which indicates the lowest radiative efficiency, the first curve 701, the third curve 703, the fourth curve 704, and the fifth curve 705 can indicate sufficient efficiency for use with external electronic devices (e.g., Figure 2a The radiation efficiency of communication with external electronic devices 300. The wearable device 101 according to the embodiment may have a housing 220 (e.g., including only conductive portions 710) in addition to the housing 220. Figure 7a Other structures besides 700b) (e.g., Figure 7a (700a, 700c, 700d and 700e).

[0126] Reference Figure 7c The shape of the non-conductive portion 720 can be varied. For example, the non-conductive portion 720 can be formed in the first housing portion 221 exposed to the outside. For example, the shape of the non-conductive portion 720 can be implemented as follows: Figure 7cThe examples shown are numerous, but not limited to. For instance, since the conductive portion 710 and the non-conductive portion 720 are visible from the outside, the conductive portion 710 and the non-conductive portion 720 can also be used as design elements. For example, by shaping the non-conductive portion 720 in a distinctive way, an external design of the conductive portion 710 and the non-conductive portion 720 that are visible from the outside can be formed.

[0127] Figure 8a A portion of a substrate according to an embodiment is shown. Figure 8b This is a graph showing the radiation efficiency of the antenna based on the width of the filled cut area.

[0128] Reference Figure 8a The filling cut area 213 can be located between the first portion 211 and the second portion 212. For example, the filling cut area 213 can space the first portion 211 from the second portion 212. For example, the gap between the first portion 211 and the second portion 212 can be determined by the width of the filling cut area 213. For example, a wireless communication circuit disposed on the first portion 211 (e.g., Figure 2c The electrical signal provided by the wireless communication circuit 192 can be transmitted to the feed point 214 located in the second part 212 via the feed path 215 located in the fill cut region 213.

[0129] For example, at least a portion of the substrate 210 can operate as a dipole antenna using the first portion 211, the second portion 212, and the filled cut region 213. When at least a portion of the substrate 210 operates as a dipole antenna, the width W of the filled cut region 213 is not limited to a specified size.

[0130] Reference Figure 8b The curve 800, even when filling the cut area (e.g., Figure 8a The width of the filled cutting area 213) (e.g., Figure 8a When the width W changes, the substrate (e.g., Figure 8a At least a portion of the substrate 210 can also have sufficient radiation efficiency to operate as a dipole antenna. The x-axis of graph 800 is frequency (in gigahertz (GHz)) and the y-axis of graph 800 is radiation efficiency (in decibels (dB)).

[0131] Figure 8b The first graph 801 shows the radiation efficiency of a dipole antenna with substantially the same dimensions as the substrate 210. Figure 8b The second graph 802 shows the radiation efficiency of the antenna, which includes at least a portion of the substrate 210, when the width W of the filled cut region 213 is about 0.2 mm. Figure 8bFigure 803 shows the radiation efficiency of an antenna including at least a portion of the substrate 210 when the width W of the filled cut region 213 is approximately 2 mm.

[0132] When comparing the first curve 801, the second curve 802, and the third curve 803, they can indicate similar radiation efficiencies in a frequency range between approximately 2.3 GHz and approximately 2.5 GHz. For example, for a frequency of approximately 2.4 GHz, the first curve 801 can indicate a higher radiation efficiency than the second curve 802 and the third curve 803, but the difference in radiation efficiency may be small. For example, the difference in radiation efficiency between the first curve 801 and the second curve 802 can be approximately 0.5 dB, and the difference in radiation efficiency between the first curve 801 and the third curve 803 can be approximately 1 dB. Due to the small difference, at least a portion of the substrate 210 can operate as a dipole antenna even when the width W of the fill cut region 213 is formed between approximately 0.2 mm and approximately 2 mm. The numerical ranges for the width W of the fill cut region 213 described above are merely exemplary to explain that the performance of an antenna including at least a portion of the substrate 210 can be substantially maintained even if the width W of the fill cut region 213 changes, and are not limited thereto.

[0133] A wearable device 101 is provided. The wearable device 101 may include a wireless communication circuit 192 and a substrate 210. The substrate 210 may include a first portion 211 on which the wireless communication circuit 192 is disposed, a second portion 212 including a feed point 214 electrically connected to the wireless communication circuit 192, and a fill-cut region 213 disposed between the first portion 211 and the second portion 212. The wireless communication circuit 192 may be configured to communicate with an external electronic device 300 by feeding the feed point 214 via the fill-cut region 213, using at least a portion of the substrate 210. According to this disclosure, the wearable device 101 may use at least a portion of the substrate 210 as an antenna radiator. For example, the substrate 210 may include a first portion 211 and a second portion 212 separated by the fill-cut region 213. For example, the substrate 210 may operate as a dipole antenna based on the potential difference between the first portion 211 and the second portion 212. Since the wearable device 101 according to the embodiment uses at least a portion of the substrate 210 as an antenna radiator, no separate arrangement space is required for the antenna radiator, thus simplifying the structure of the wearable device 101 and ensuring space for at least one electronic component 230 within the internal space of the housing 220.

[0134] For example, wearable device 101 may also include a housing 220 surrounding substrate 210. The housing 220 may be annular in shape.

[0135] For example, the substrate 210 can be deformed into a shape corresponding to the shape of the housing 220. The substrate 210 can be bent inside the housing 220 to correspond to the shape of the housing 220. According to this disclosure, since the substrate 210 is flexible, the substrate 210 can be stably disposed in the housing 220.

[0136] For example, end 210a of substrate 210 may be spaced apart from end 210b of substrate 210 opposite to end 210a within housing 220. According to this disclosure, when substrate 210 is bent to correspond to a ring shape, the two ends of substrate 210 may be spaced apart from each other, such that at least a portion of substrate 210 operates as a dipole antenna. For example, when substrate 210 is bent into a ring shape within housing 220, end 210a of substrate 210 may be spaced apart from end 210b of substrate 210 opposite to end 210a. Since end 210a is spaced apart from end 210b, the first portion 211 and the second portion 212 can be separated from each other and form a dipole antenna.

[0137] For example, wearable device 101 may further include at least one electronic component 230 disposed on substrate 210. Wireless communication circuitry 192 may be configured to communicate with external electronic device 300 by feeding power to feed point 214, using at least partially substrate 210 and at least one electronic component 230 disposed on substrate 210. According to this disclosure, since wearable device 101 can use substrate 210 and / or at least one electronic component 230 as an antenna radiator, a separate antenna radiator (e.g., conductive pattern) can be omitted within housing 220.

[0138] For example, the electrical length L1 of the first portion 211 can correspond to the electrical length L2 of the second portion 212. According to this disclosure, the two conductive electrodes of the dipole antenna can be implemented by the first portion 211 and the second portion 212.

[0139] For example, at least a portion of the substrate 210 may be configured to transmit or receive signals at a resonant frequency based on the electrical length L of the substrate 210.

[0140] For example, substrate 210 may include at least one conductor 250 extending from first portion 211 through fill cut region 213 to second portion 212, and a connecting member 270 located in fill cut region 213 and electrically connected to at least one conductor 250. According to this disclosure, an electrical connection can be provided between electronic components disposed on first portion 211 and electronic components disposed on second portion 212 via at least one conductor 250. Connecting member 270 may be a passive element (e.g., an inductor and / or capacitor) having specified parameter values ​​(e.g., inductance and / or capacitance). For example, connecting member 270 may be an inductor with a specified inductance value, such that at least one conductor 250 has a reference impedance.

[0141] For example, wearable device 101 may further include a processor 120 disposed on substrate 210 and at least one electronic component 230 disposed on substrate 210. At least one conductor 250 may include a first conductor 251 electrically connecting the processor 120 and the at least one electronic component 230, and a second conductor 252 electrically connecting a ground plane in the first portion 211 and a ground plane in the second portion 212 and surrounding the first conductor 251. According to this disclosure, the second conductor 252 may be configured to shield against crosstalk that causes noise between signal lines in the filled cut area 213.

[0142] For example, wearable device 101 may also include a battery 189 connected to substrate 210. Wireless communication circuitry 192 may be configured to communicate with external electronic device 300 by feeding power to feed point 214, using at least part of substrate 210 and battery 189. According to this disclosure, battery 189 may operate as part of an antenna radiator.

[0143] For example, at least a portion of the substrate 210 may be configured to operate as a dipole antenna based on the potential difference between the first portion 211 and the second portion 212.

[0144] For example, wearable device 101 may also include a housing 220 surrounding substrate 210. Housing 220 may include a non-conductive material. According to this disclosure, when housing 220 includes a non-conductive material, electromagnetic waves radiated from the interior of housing 220 can easily pass through housing 220.

[0145] For example, wearable device 101 may also include a housing 220 surrounding substrate 210. Housing 220 may include conductive portions 710 and non-conductive portions 720. According to this disclosure, when housing 220 includes a conductive material, the non-conductive portions 720 may be configured to radiate electromagnetic waves from the interior of housing 220.

[0146] For example, the non-conductive portion 720 may include at least one of a first non-conductive portion 721 or a second non-conductive portion 722, wherein the first non-conductive portion 721 is formed in a first region of the housing 220 and is at least partially aligned with the fill cut region 213, and the second non-conductive portion 722 is formed in a second region of the housing 220 and is at least partially aligned with the end of the substrate 210.

[0147] For example, housing 220 may include a first housing portion 221 exposed to the outside when wearable device 101 is worn on a user's body, and a second housing portion 222 that at least partially contacts the user's body when wearable device 101 is worn on a user's body. Non-conductive portion 720 may be formed on the first housing portion 221.

[0148] A wearable device 101 is provided. The wearable device 101 may include a housing 220, a substrate 210, and a wireless communication circuit 192. The housing 220 may have an annular shape. The substrate 210 may include a first portion 211, a second portion 212 spaced apart from the first portion 211, and a fill cut region 213 disposed between the first portion 211 and the second portion 212. The substrate 210 may be disposed within the housing 220. The wireless communication circuit 192 may be configured to transmit signals to or receive signals from an external electronic device 300 at a specified frequency using at least a portion of the substrate 210. The wireless communication circuit 192 may be disposed on the first portion 211. The second portion 212 may be located at the end of the second portion 212 facing the first portion 211. The second portion 212 may include a feed point 214 electrically connected to the wireless communication circuit 192.

[0149] For example, the substrate 210 can be deformed into a shape corresponding to the shape of the housing 220. The substrate 210 can be bent inside the housing 220 to correspond to the shape of the housing 220.

[0150] For example, wearable device 101 may further include at least one electronic component 230 disposed on substrate 210. Wireless communication circuit 192 may be configured to communicate with external electronic device 300 by feeding power to feed point 214 and by using substrate 210 and at least one electronic component 230 disposed on substrate 210 in at least part.

[0151] For example, the electrical length L1 of the first part 211 can correspond to the electrical length L2 of the second part 212.

[0152] For example, substrate 210 may include at least one conductor 250 extending from first portion 211 through fill cut region 213 to second portion 212, and a connecting member 270 located in fill cut region 213 and electrically connected to at least one conductor 250.

[0153] The electronic device according to various embodiments can be one of a variety of types of electronic devices.
