Description

Electronic device including an antenna and wireless communication method using the antenna

[0001] Embodiments disclosed in this document relate to an electronic device including an antenna and a wireless communication method using the antenna.

[0002] Electronic devices (or portable communication devices) such as smartphones and tablet PCs can perform wireless communication via antennas. Electronic devices may include multiple antennas to respond to wireless communication signals across various bands. Recently, foldable, rollable, or slideable electronic devices have been released.

[0003] Electronic devices performing wireless communication can improve antenna performance by utilizing aperture tuners and impedance tuners (AITs). For example, the aperture tuner and impedance tuner of a typical bar-shaped mobile electronic device can be optimized for the communication band supported by the antenna. An aperture tuner can perform tuning over a relatively large range, while an impedance tuner can perform tuning over a relatively small range.

[0004] Meanwhile, displays contain a variety of conductive materials, which can significantly impact the operation of surrounding antennas. For example, foldable electronic devices can apply different tuning codes to their aperture tuners depending on their closed and unfolded states, thereby preventing degradation of wireless communication performance due to changes in display size.

[0005] According to one embodiment, an electronic device comprises a housing including a first housing portion and a second housing portion configured to movably engage with the first housing portion between a retracted position and an extended position, a flexible display coupled to the first housing portion and the second housing portion such that a size of a visible area from a front side of the housing changes as the housing moves between the retracted position and the extended position, an actuator configured to move the second housing portion with respect to the first housing portion, a first antenna performing wireless communication using a first portion of a side frame of the first housing portion, a second antenna performing wireless communication using a second portion of the side frame of the first housing portion, a sensor module detecting movement of the first housing portion or the second housing portion, a communication circuit transmitting and receiving a wireless signal through the first antenna or the second antenna, and a tune code of a tuner included in each of the first antenna or the second antenna based on an extended distance of the display. May include a changing processor.

[0006] An electronic device according to one embodiment may include a housing including a first housing part and a second housing part, a flexible display whose display area is reduced or expanded according to a sliding operation of the first housing part and the second housing part, a first antenna performing wireless communication using a first portion of a side frame of the first housing part, a second antenna performing wireless communication using a second portion of the side frame of the first housing part, a sensor module detecting a sliding operation of the first housing part or the second housing part, a communication circuit transmitting and receiving a wireless signal through the first antenna or the second antenna, and a processor changing a tune code of a tuner included in each of the first antenna or the second antenna at different timings based on an expansion distance of the display.

[0007] An electronic device according to one embodiment may include a housing including a first housing portion and a second housing portion, a display configured to reduce or expand a size of a display area according to relative movement of the first housing portion and the second housing portion, a first antenna configured to perform wireless communication using a first portion of a side frame of the first housing portion, a second antenna configured to perform wireless communication using a second portion of the side frame of the first housing portion, a sensor module configured to detect reduction or expansion of the flexible display based on relative movement of the first housing portion or the second housing portion, a communication circuit configured to transmit and receive a wireless signal through at least one of the first antenna and the second antenna, and a processor configured to change a first tune code of a first tuner included in the first antenna based on an expansion distance of the display and to change a second tune code of a second tuner included in the second antenna based on the expansion distance of the display. An expansion distance over which the first tune code is changed and an expansion distance over which the second tune code is changed may be different from each other.

[0008] According to one embodiment, a method may be performed in an electronic device including a communication circuit and a display configured to reduce or expand a size of a display area according to relative movement of a first housing portion and a second housing portion. The method may include, when reducing or expanding the display area is detected, determining an expansion distance of the display, changing a first tune code of a first tuner included in a first antenna that performs wireless communication using a first part of a side frame of the first housing portion based on the expansion distance, changing a second tune code of a second tuner included in a second antenna that performs wireless communication using a second part of the side frame of the first housing portion based on the expansion distance, and changing a tune code of a second tuner included in a second antenna that performs wireless communication using the second part of the side frame of the first housing portion based on the expansion distance. An expansion distance over which the first tune code is changed and an expansion distance over which the second tune code is changed may be different from each other.

In connection with the description of the drawings, similar reference numerals may be used for similar components.

[0018] FIG. 1 is a block diagram of an electronic device (101) within a network environment (100) according to various embodiments. Referring to FIG. 1, in the network environment (100), the electronic device (101) may communicate with an electronic device (102) via a first network (198) (e.g., a short-range wireless communication network), or may communicate with an electronic device (104) or a server (108) via a second network (199) (e.g., a long-range wireless communication network).

For example, when the electronic device (101) includes the main processor (121) and the auxiliary processor (123), the auxiliary processor (123) may be configured to use less power than the main processor (121) or to be specialized for a given function. The auxiliary processor (123) may be implemented separately from the main processor (121) or as a part thereof.

[0020] The auxiliary processor (123) may control at least a portion of functions or states associated with at least one component (e.g., a display module (160), a sensor module (176), or a communication module (190)) of the electronic device (101), for example, on behalf of the main processor (121) while the main processor (121) is in an inactive (e.g., sleep) state, or together with the main processor (121) while the main processor (121) is in an active (e.g., application execution) state. In one embodiment, the auxiliary processor (123) (e.g., an image signal processor or a communication processor) may be implemented as a part of another functionally related component (e.g., a camera module (180) or a communication module (190)). In one embodiment, the auxiliary processor (123) (e.g., a neural network processing unit) may include a hardware structure specialized for processing artificial intelligence models. The artificial intelligence models may be generated through machine learning. This learning can be performed, for example, in the electronic device (101) itself where artificial intelligence is performed, or can be performed through a separate server (e.g., server (108)).

The speaker can be used for general purposes, such as multimedia playback or recording playback. The receiver can be used to receive incoming calls. In one embodiment, the receiver can be implemented separately from the speaker or as part of the speaker.

[0025] The display module (160) can visually provide information to an external party (e.g., a user) of the electronic device (101). The display module (160) may include, for example, a display, a holographic device, or a projector and a control circuit for controlling the device. According to one embodiment, the display module (160) may include a touch sensor configured to detect a touch, or a pressure sensor configured to measure the intensity of a force generated by the touch.

[0026] The audio module (170) can convert sound into an electrical signal, or vice versa, convert an electrical signal into sound.

[0027] The sensor module (176) can detect the operating status (e.g., power or temperature) of the electronic device (101) or the external environmental status (e.g., user status) and generate an electrical signal or data value corresponding to the detected status. According to one embodiment, the sensor module (176) can include, for example, a gesture sensor, a gyro sensor, a barometric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an IR (infrared) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illuminance sensor.

[0028] The interface (177) may support one or more designated protocols that may be used to directly or wirelessly connect the electronic device (101) with an external electronic device (e.g., the electronic device (102)). In one embodiment, the interface (177) may include, for example, a high definition multimedia interface (HDMI), a universal serial bus (USB) interface, an SD card interface, or an audio interface.

[0029] The connection terminal (178) may include a connector through which the electronic device (101) may be physically connected to an external electronic device (e.g., electronic device (102)). According to one embodiment, the 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).

According to one embodiment, the haptic module (179) can include, for example, a motor, a piezoelectric element, or an electrical stimulation device.

[0031] The camera module (180) can capture still images and videos. According to one embodiment, the camera module (180) may include one or more lenses, image sensors, image signal processors, or flashes.

[0032] The power management module (188) can manage power supplied to the electronic device (101). According to one embodiment, the power management module (188) can be implemented as, for example, at least a part of a power management integrated circuit (PMIC).

[0033] A battery (189) may power at least one component of the electronic device (101). In one embodiment, the battery (189) may include, for example, a non-rechargeable primary battery, a rechargeable secondary battery, or a fuel cell.

[0034] The communication module (190) may support the establishment of 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 the performance of communication through the established communication channel. The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (194) (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0035] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (192) can support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna. The wireless communication module (192) can support various requirements specified in the electronic device (101), an external electronic device (e.g., the electronic device (104)), or a network system (e.g., the second network (199)). According to one embodiment, the wireless communication module (192) can support a peak data rate (e.g., 20 Gbps or more) for eMBB realization, a loss coverage (e.g., 164 dB or less) for mMTC realization, or a U-plane latency (e.g., 0.5 ms or less for downlink (DL) and uplink (UL), or 1 ms or less for round trip) for URLLC realization.

[0036] The antenna module (197) can transmit or receive signals or power to or from an external device (e.g., an external electronic device). In one embodiment, the antenna module (197) may include an antenna including a radiator formed of a conductor or a conductive pattern formed on a substrate (e.g., a PCB). In one embodiment, the antenna module (197) may include a plurality of antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication method used in a communication network, such as the first network (198) or the second network (199), may be selected from the plurality of antennas, for example, by the communication module (190). A signal or power may be transmitted or received between the communication module (190) and an external electronic device via the at least one selected antenna. In some embodiments, in addition to the radiator, another component (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as a part of the antenna module (197).

[0037] According to various embodiments, the antenna module (197) may form a mmWave antenna module. In one embodiment, the mmWave antenna module may include a printed circuit board, an RFIC disposed on or adjacent a first side (e.g., a bottom side) of the printed circuit board and capable of supporting a designated high-frequency band (e.g., a mmWave band), and a plurality of antennas (e.g., an array antenna) disposed on or adjacent a second side (e.g., a top side or a side side) of the printed circuit board and capable of transmitting or receiving signals in the designated high-frequency band.

[0038] At least some of the above components can be interconnected and exchange signals (e.g., commands or data) with each other via a communication method between peripheral devices (e.g., a bus, GPIO (general purpose input and output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface)).

[0039] According to one embodiment, commands or data may be transmitted or received between the electronic device (101) and an external electronic device (104) via a server (108) connected to a second network (199). Each of the external electronic devices (102 or 104) may be the same or a different type of device as the electronic device (101). According to one embodiment, all or part of the operations executed in the electronic device (101) may be executed in one or more of the external electronic devices (102, 104, or 108). For example, when the electronic device (101) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (101) may, instead of or in addition to executing the function or service itself, request one or more external electronic devices to perform the function or at least a part of the service. One or more external electronic devices that receive the request may execute at least a portion of the requested function or service, or an additional function or service related to the request, and transmit the result of the execution to the electronic device (101). The electronic device (101) may process the result as is or additionally and provide it as at least a portion of a response to the request. For this purpose, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example. The electronic device (101) may provide an ultra-low latency service by using distributed computing or mobile edge computing, for example. In another embodiment, the external electronic device (104) may include an Internet of Things (IoT) device. The server (108) may be an intelligent server utilizing machine learning and / or a neural network. According to one embodiment, the external electronic device (104) or the server (108) may be included in the second network (199).The electronic device (101) can be applied to intelligent services (e.g., smart home, smart city, smart car, or healthcare) based on 5G communication technology and IoT-related technology.

[0040]

[0041] Figures 2a and 2b illustrate an electronic device according to one embodiment.

[0042] Referring to FIGS. 2A and 2B, an electronic device (e.g., electronic device (101) of FIG. 1) (200) may be a slidable type or rollable type device with an expandable display (250). However, this is merely an example, and the electronic device (200) may be of any form that can expand and contract the physical size of the display area of ​​the electronic device.

[0043] The electronic device (200) may include a first housing portion (or first housing portion) (210), a second housing portion (or second housing portion) (240), and a display (or flexible display) (e.g., a display module (160) of FIG. 1) (250).

[0044] The first housing part (210) and the second housing part (240) may be collectively referred to as a 'housing', and may include various components (e.g., a processor (e.g., a processor (120) of FIG. 1), a memory (e.g., a memory (130) of FIG. 1), a battery (e.g., a battery (189) of FIG. 1), a circuit board, a sensor module (e.g., a sensor module (176) of FIG. 1), a camera module (e.g., a camera module (180) of FIG. 1)) required for the operation of the electronic device (200)) therein.

[0045] An electronic device (or portable communication device, mobile electronic device) (200) can operate in one of a first state (e.g., a closed state or a collapsed mode) (Fig. 2a), a second state (e.g., an open state or an expanded mode) (Fig. 2b), and a third state between the first and second states (e.g., a partially open state or a partially expanded mode).

[0046] The first state, second state, or third state of the electronic device (200) may be determined based on the relative position of the second housing portion (240) with respect to the first housing portion (210). The display (250) may be configured to reduce or enlarge the size of the display area in response to the relative movement of the first housing portion (210) and the second housing portion (240). The electronic device (200) may be transformed into the first state, second state, or third state by a user's manipulation or mechanical operation.

[0047] The first housing portion (210) and the second housing portion (240) may be provided to movably engage with each other between a retracted position (first state) and an extended position (second state). The first housing portion (210) and the second housing portion (240) may be coupled to each other so as to be able to slide relative to each other. For example, the first housing portion (210) may be a fixed structure, and the second housing portion (240) may be a structure that is able to slide relative to the first housing portion (210). The second housing portion (240) may be coupled to one side of the first housing portion (210) so as to be able to slide in both directions (e.g., +x / -x directions) relative to the first housing portion (210). Although not shown in FIG. 2, the electronic device (200) may include an actuator for sliding the first housing portion (210) or the second housing portion (240). For example, the electronic device (200) may include an actuator configured to move the second housing portion relative to the first housing portion.

[0048] The electronic device (200) can be transformed from the first state to the second state, or from the second state to the first state, as the second housing part (240) slides relative to the first housing part (210). For example, as the second housing part (240) moves in the second direction (D2) relative to the first housing part (210) in the first state (Fig. 2a), the electronic device (200) can be transformed from the first state (Fig. 2a) to the second state (Fig. 2b). Conversely, as the second housing part (240) moves in the first direction (D1) relative to the first housing part (210) in the second state (Fig. 2b), the electronic device (200) can be transformed from the second state (Fig. 2b) to the first state (Fig. 2a).

[0049] The first state (Fig. 2a) may be a state in which the area (or size) of the display (250) exposed to the front of the electronic device (200) is reduced to the minimum. The first state may be a state in which a part of the second housing part (240) (e.g., a side part (243, 244) facing the y+ or y- direction) is introduced into the first housing part (210) and is not visible from the outside. In the first state, the second housing part (240) may be in a state in which most of the second housing part (240) overlaps with the first housing part (210). That is, in the first state, most of the front area of ​​the second housing part (240) may overlap with the front area of ​​the first housing part (210).

[0050] The second state (Fig. 2b) may be a state in which the area (or size) of the display (250) exposed to the front of the electronic device (200) is expanded to the maximum. For example, the second state may be a state in which a part (243, 244) of the second housing part (240) is pulled out from the first housing part (210). In the second state, the second housing part (240) may partially overlap with the first housing part (210) or may not overlap with it. That is, in the second state, a part or minor area of ​​the front surface of the second housing part (240) may overlap with the front surface surface of the first housing part (210), or the front surface of the second housing part (240) may not overlap with the front surface surface of the first housing part (210).

[0051] The display (250) can change the size of the area visible from the front side of the electronic device (200) as the first housing portion (210) and the second housing portion (240) move between the contracted position (first state) and the extended position (second state). For example, the flexible display (250) is coupled to the first housing portion (210) and the second housing portion (240), and the size of the display area visible from the front side of the housing can change as the housing moves between the folded position and the extended position. For example, the size (or area) of the display (250) visible from the front side (e.g., the display area) of the electronic device (200) can change in response to the sliding motion of the second housing portion (240).

[0052] The display (250) can have an exposure area (or display area) that expands or contracts in size according to a sliding motion of the second housing (240) while being supported by at least one of the first housing (210) and the second housing (240). That is, the display (250) (or display area) can be supported by at least one of the first housing or the second housing. The display (250) can include at least a partially flexible portion. That is, at least a portion of the display (250) can be flexible so that the display area can be expanded or contracted in size when the housing is manipulated (for example, when there is relative movement between the first housing (210) and the second housing (240).

[0053] The display (250) may include a base area (250-1) and an extended area (250-2) extending from the base area (250-1). The base area (250-1) may be maintained in a state exposed to the front of the electronic device (200). The area of ​​the extended area (250-2) exposed to the front of the electronic device (200) may vary depending on the state of the electronic device (200). The extended area (250-2) may extend from one side (e.g., in the +x direction) of the base area (250-1). For example, the base area (250-1) may refer to a portion of the display (250) that is visually exposed to the front of the electronic device (200) in a first state. The extended area (250-2) may represent an area of ​​the electronic device (200) that is not visible from the front of the electronic device (200) in the first state (e.g., located inside the electronic device (200) or behind the first housing portion (210). In the second state, the extended area (250-2) is at least partially visually exposed to the front of the electronic device (200) (e.g., by protruding outside the electronic device (200) or by protruding behind the first housing portion (210).

[0054] The first state (Fig. 2a) may be a state in which the basic region (250-1) forms the front of the electronic device (200) (i.e., visible to a user looking at the front of the electronic device (200), and the extended region (250-2) is located on the inside (or the back) of the first housing portion (210). The second state (Fig. 2b) may be a state in which at least a portion of the extended region (250-2) forms the front of the electronic device (200) together with the basic region (250-1). In the second state, the electronic device (200) may have an expanded exposure area of ​​the display (250) by additionally exposing the extended region (250-2) to the front of the electronic device (200).

[0055] The display (250) is visually exposed to the front of the electronic device (200) (i.e., is visible to a user looking at the front of the electronic device (200)) and can display certain visual information (or screen). For example, in the first state (Fig. 2a), the display (250) can display visual information through the basic area (250-1). In the second state (Fig. 2b), the display (250) can display visual information through a part of the extended area (250-2) and the basic area (250-1). In the second state, the electronic device (200) can display content on a part of the extended area (250-2) together with the basic area (250-1), and can provide a screen display area that is expanded compared to the first state.

[0056] In the first state, the size of the exposure area of ​​the display (250) may be a first size. In the second state, the size of the exposure area of ​​the display (250) may be a second size larger than the first size. For example, the width of the display (250) forming the exposure area in the first state may be a first width (W1), and the width of the display (250) forming the exposure area in the second state may be a second width (W2). The first size and the first width (W1) may be the minimum size and minimum width of the exposure area of ​​the display (250), respectively. The second size and the second width (W2) may be the maximum size and maximum width of the exposure area of ​​the display (250), respectively.

[0057] The electronic device (200) may operate in a third state, which is any intermediate state defined between the first state (Fig. 2a) and the second state (Fig. 2b). In the third state, the width of the display (250) forming the exposure area may be greater than the first width (W1) and less than the second width (W2).

[0058] According to one embodiment, the electronic device (200) may include a sensor therein that detects an expansion distance of the display (250) (or a sliding distance or other relative movement of the first housing portion (210) and the second housing portion (240). The sensor may detect or measure information indicating a relative movement of the first housing portion (210) and the second housing portion (240) and / or the expansion distance. A processor (e.g., processor 120) may determine the expansion distance based on the information obtained through the sensor. For example, the sensor may be disposed adjacent to a multi-joint structure formed on the back surface of the display (250). The sensor may detect movement or rotation of the multi-joint structure to measure the expansion distance of the display (250). The electronic device (200) may measure the expansion distance of the display (250) and control the operation of an antenna formed using a side frame of the first housing portion (210) in response to the measured expansion distance. However, this is merely an example, and the electronic device may include any sensor type and / or arrangement suitable for detecting information representing extended distances.

[0059]

[0060] Fig. 3 illustrates an antenna structure formed on a side frame of an electronic device according to one embodiment. Fig. 3 is exemplary and is not limiting.

[0061] Referring to FIG. 3, a side frame (300) of an electronic device (e.g., the electronic device (101) of FIG. 1, the electronic device (200) of FIGS. 2A and 2B) may be utilized as an antenna radiator. The side frame (300) may include a first frame portion (301) and a second frame portion (302).

[0062] The first frame portion (301) may be disposed at the bottom of an electronic device (e.g., the electronic device (101) of FIG. 1, the electronic device (200) of FIGS. 2A and 2B) and may include a plurality of conductive members (or parts or regions) and a plurality of non-conductive members (or parts or regions) arranged between the plurality of conductive members. For example, as illustrated in FIG. 3, the first frame portion (301) may include a first conductive portion (310) and a second conductive portion (320). Segmented portions (311, 312, 313) may be formed at both ends of the first conductive portion (310) and the second conductive portion (320), and a non-conductive member may be disposed in each of the segmented portions. That is, a non-conductive member or non-conductive region may be arranged at both ends of the first conductive portion (310) and the second conductive portion (320). The same non-conductive member or non-conductive region may be arranged between one end of the first conductive portion (310) and one end of the second conductive portion (320) (i.e., the split portion (312)).

[0063] The second frame portion (302) may be disposed on the top of an electronic device (e.g., the electronic device (101) of FIG. 1, the electronic device (200) of FIGS. 2A and 2B) and may include a plurality of conductive members (or parts or regions) and a plurality of non-conductive members (or parts or regions) arranged between the plurality of conductive members. For example, as illustrated in FIG. 3, the second frame portion (302) may include a third conductive portion (350), a fourth conductive portion (360), and a fifth conductive portion (370). Segmented portions (351, 352, 353, 354) may be formed at both ends of the third conductive portion (350), the fourth conductive portion (360), and the fifth conductive portion (370), and a non-conductive member may be disposed in each of the segmented portions. That is, a non-conductive member or non-conductive region may be arranged at each end of the third conductive portion (350), the fourth conductive portion (360), and the fifth conductive portion (370). The same non-conductive member or region may be arranged between the ends. The same non-conductive member or non-conductive region may be arranged between one end of the third conductive portion (350) and one end of the fourth conductive portion (360) (i.e., the split portion (351)).

[0064] The arrangement of the conductive components is merely an example, and the plurality of conductive members and the plurality of non-conductive members arranged between the plurality of conductive members may be included at any suitable location within the housing of the electronic device (e.g., the electronic device (101) of FIG. 1, the electronic device (200) of FIGS. 2A and 2B). For example, at least one of the first housing portion (210) and the second housing portion (240) may include the plurality of conductive members and the plurality of non-conductive members arranged between the plurality of conductive members.

[0065] Each conductive portion may be used by (or as a part of) an antenna. For example, a first antenna may be configured to transmit and receive a wireless signal using a first conductive element among a plurality of conductive elements, and a second antenna may be configured to transmit and receive a wireless signal using a second conductive element among a plurality of conductive elements.

[0066] A plurality of conductive members used by (or as part of) the antenna may be arranged on the same side of the electronic device (e.g., the electronic device (101) of FIG. 1, the electronic device (200) of FIGS. 2A and 2B). For example, the first conductive member and the second conductive member used in the first antenna and the second antenna, respectively, may be arranged on the same side of the electronic device.

[0067] Antennas utilizing each conductive portion can transmit and receive signals in a designated frequency band. When the size of a display (e.g., a display module (160) of FIG. 1, a display (250) of FIGS. 2A and 2B) or a display area of ​​an electronic device (e.g., an electronic device (101) of FIG. 1, an electronic device (200) of FIGS. 2A and 2B) is expanded or reduced, the arrangement of conductive structures and electrical structures around each antenna may change. For example, the resonance around the antenna may change as the display moves, which may degrade the communication performance of the antenna.

[0068] The electronic device may change the tune code applied to the tuner included in each antenna in response to the expansion or reduction distance of the extended display. For example, the first tune code of the first tuner included in the first antenna may change according to the expansion distance of the display, and the second tune code of the second tuner included in the second antenna may change according to the expansion distance of the display. The expansion distance at which the first tune code is changed may be different from the expansion distance at which the second tune code is changed. For example, the electronic device may change the first tune code for the first antenna using the first conductive portion (310) based on a first threshold value that reflects the expansion or reduction distance of the display. For example, when the expansion distance exceeds the first threshold value due to the expansion of the display, the electronic device may change the first tune code from the first code set to the second code set, and when the expansion distance falls below the first threshold value due to the reduction of the display, the electronic device may change the first tune code from the second code set to the first code set. The electronic device may change the second tune code based on a second threshold value greater than the first threshold value for the second antenna using the second conductive portion (320). For example, when the expansion distance exceeds the second threshold value due to the expansion of the display, the electronic device may change the second tune code from the third code set to the fourth code set, and when the expansion distance falls below the second threshold value due to the reduction of the display, the electronic device may change the second tune code from the fourth code set to the third code set. Additional information regarding the change of the tune code of the antenna tuner according to the expansion distance of the display may be provided through the drawings below.

[0069]

[0070] Figure 4 illustrates a tuner of an antenna according to one embodiment.

[0071] Referring to FIG. 4, an antenna module (or antenna device) (401) may include a communication circuit (405), an impedance tuner (420), an aperture tuner (430), and a radiator (440). The impedance tuner (420) and the aperture tuner (430) may be collectively referred to as an 'antenna tuner'.

[0072] The communication circuit (405) may be configured to transmit and / or receive wireless communication signals via an antenna (e.g., via a radiator). The communication circuit (405) may process wireless communication signals received via a radiator (440). The communication circuit (405) may control elements within the impedance tuner (420) and / or the aperture tuner (430).

[0073] In one embodiment, the communication circuit (405) may include a non-volatile memory or storage element therein. The communication circuit (405) may include at least one tune code associated with the control of the aperture tuner (430). For example, the at least one tune code may be stored in the non-volatile memory or storage element. The communication circuit (405) may be configured to change the tune code in response to receiving a control signal from a processor (e.g., the processor (120) of FIG. 1 ). For example, the communication circuit (405) may receive information regarding an expansion distance of the display from the processor (e.g., the processor (120) of FIG. 1 ). The communication circuit (405) may change the tune code applied to the aperture tuner (430) in response to the expansion distance of the display. The state of an element within the aperture tuner (430) may be changed according to the changed tune code.

[0074] The impedance tuner (420) can adjust the impedance characteristics of the antenna module (401). For example, the impedance tuner (420) can include at least one capacitor, at least one inductor, at least one resistor, and / or at least one switch. The impedance tuner (420) can increase or decrease the impedance required to minimize the reflection coefficient between the signal processing path and the radiator (440). The impedance tuner (420) can be referred to as an 'impedance matching circuit.' The impedance tuner (420) can perform precise range tuning for the wireless communication signal processed through the aperture tuner (430). The impedance tuner (420) can perform tuning in a smaller range than the aperture tuner (430). For example, after tuning by the aperture tuner (430), the impedance tuner (420) can perform additional tuning by a closed loop method.

[0075] The aperture tuner (430) can adjust the characteristics of the radiator (440). The aperture tuner (430) can include at least one capacitor, at least one inductor, at least one resistor, and / or at least one switch. The aperture tuner (430) is connected to the radiator (440) in a direction different from the signal processing path of the impedance tuner (420), and can adjust circuit characteristics required to optimize the resonant frequency of the radiator (440). The aperture tuner (430) can perform tuning in a larger range than the impedance tuner (420).

[0076] According to one embodiment, the aperture tuner (430) can change the operating state of internal components according to a tune code transmitted from the communication circuit (405). For example, the aperture tuner (430) can include a plurality of switches and a variable capacitor, and can be configured to change the states of the variable capacitor and / or the plurality of switches according to the tune code. The aperture tuner (430) can operate with a first code set transmitted from the communication circuit (405). The first code set can correspond to a first state of the electronic device (e.g., a closed state or a reduced mode). The aperture tuner (430) can change (or change) the states of the switches and set the values ​​of the variable capacitors according to the first code set. Depending on the expansion of the display, the aperture tuner (430) can receive a second code set from the communication circuit (405). The second code set can correspond to a second state of the electronic device (e.g., an open state or an expanded mode). The aperture tuner (430) can change the state of the switches or the value of the variable capacitor according to the second code set.

[0077] The radiator (440) can transmit and receive wireless communication signals. The radiator (440) can form an electrical path for wireless communication. The radiator (440) can be a conductor for radiating or detecting wireless communication signals. The radiator (440) can have a shape corresponding to the frequency of the signal to be processed, and can be placed at a specific location (e.g., a side frame) of an electronic device (e.g., the electronic device (101) of FIG. 1, the electronic device (200) of FIGS. 2A and 2B). For example, the radiator (440) can be a conductive part, such as one of a plurality of conductive parts (e.g., conductive parts 310, 320, 350, 360, 370) constituting the side frame of FIG. 3.

[0078]

[0079] FIG. 5 illustrates antenna operation according to a change in the size of a display according to one embodiment.

[0080] Referring to FIG. 5, an electronic device (e.g., an electronic device (101) of FIG. 1, an electronic device (200) of FIGS. 2A and 2B) (500) may be a slidable type or a rollable type device in which a display (505) (e.g., a display module (160) of FIG. 1, a display (250) of FIGS. 2A and 2B) is expanded. However, this is merely an example, and it should be understood that the electronic device (500) may be of any form that can expand and contract the physical size of the display area of ​​the electronic device. The electronic device (500) may operate in one of a first state (e.g., a closed state or a reduced mode), a second state (e.g., an open state or an expanded mode), and a third state (e.g., a partially opened state or a partially expanded mode) between the first state and the second state.

[0081] As the display (505) expands, the arrangement of conductive structures or electrical structures around the antenna included in the electronic device (500) may change, and accordingly, the resonance characteristics of the antenna may change. To maintain stable wireless communication performance, the electronic device (500) may change the tune code of the aperture tuner (e.g., the aperture tuner (430) of FIG. 4) depending on the degree of expansion of the display (505).

[0082] The first frame portion (lower frame) (501) may include a first conductive portion (or first conductive member) (510), a second conductive portion (or second conductive member) (520), a third conductive portion (or third conductive member) (530), a first non-conductive member (511), and a second non-conductive member (512). The first conductive portion (510) and the second conductive portion (520) may be separated from each other via the first non-conductive member (511). The first conductive portion (510) and the third conductive portion (530) may be separated from each other via the second non-conductive member (512).

[0083] The first conductive portion (510) may have a first length (L1). The second conductive portion (520) may have a second length (L2). The third conductive portion (530) may have a third length (L3).

[0084] According to one embodiment, the first antenna (Main1) can transmit and receive wireless communication signals using the first conductive portion (510). The second antenna (Main2) can transmit and receive wireless communication signals using the second conductive portion (520). The third antenna (Sub1) can transmit and receive wireless communication signals using the third conductive portion (530).

[0085] According to one embodiment, the electronic device (500) may be configured to change at least one tune code by comparing the extended distance with a length of at least one conductive portion among a plurality of conductive portions (e.g., a plurality of conductive portions forming a side frame). The plurality of conductive portions may be used by (or as part of) the antenna. For example, the electronic device may determine whether to change the tune code of the antenna based on a comparison between the extended distance and a length of at least one conductive portion including a conductive portion used by the antenna. For example, the electronic device may be configured to change the tune code of a first tuner included in a first antenna by comparing the extended distance with a length of a first conductive portion used by a first antenna. The electronic device may be configured to change the tune code of a second tuner included in a second antenna by comparing the extended distance with a length of one of the first conductive portion and the second conductive portion used by a second antenna. For example, comparing the length of the extension distance to the length of the conductive portion may include determining whether the extension distance is greater than or less than the length of the conductive portion and changing the tune code accordingly.

[0086] For example, when the display extension length (Z) is 0, a pre-stored closing code (i.e., a tune code corresponding to the first state) may be applied to the first antenna (Main1), the second antenna (Main2), and the third antenna (Sub1), respectively. The electronic device (500) may apply the first closing code (A1_Roll_Close) to the aperture tuner of the first antenna (Main1), the second closing code (A2_Roll_Close) to the aperture tuner of the second antenna (Main2), and the third closing code (A3_Roll_Close) to the aperture tuner of the third antenna (Sub1).

[0087] When the display extension length (Z) is less than the third length (L3) of the third conductive portion (530) (0 < Z < L3), the electronic device (500) can apply a pre-stored open code (i.e., a tune code corresponding to the second state and / or the third state) to the third antenna (Sub1) using the third conductive portion (530), and maintain a close code to each of the first antenna (Main1) using the first conductive portion (510) and the second antenna (Main2) using the second conductive portion (520). For example, the electronic device (500) can apply a third open code (A3_Roll_Open) to the aperture tuner of the third antenna (Sub1), maintain a first close code (A1_Roll_Close) to the aperture tuner of the first antenna (Main1), and maintain a second close code (A2_Roll_Close) to the aperture tuner of the second antenna (Main2).

[0088] When the display extension length (Z) increases and the display extension length (Z) is greater than the third length (L3) and less than the sum of the first length (L1) and the third length (L3) (L3 < Z < (L1+L3)), the electronic device (500) can apply a pre-stored open code to the first antenna (Main1) using the first conductive portion (510) and maintain a close code to the second antenna (Main2) using the second conductive portion (520). For example, the electronic device (500) can apply the first open code (A1_Roll_Open) to the aperture tuner of the first antenna (Main1) and maintain the second close code (A2_Roll_Close) to the aperture tuner of the second antenna (Main2).

[0089] When the display extension length (Z) becomes greater than the third length (L3), a void that is not filled with the display (505) may be formed around the first conductive portion (510). Due to the change in the conductive structure around the first conductive portion (510), the resonance characteristics of the first antenna (Main1) using the first conductive portion (510) may change. If the first antenna (Main1) maintains the existing tune code, wireless communication performance using the first antenna (Main1) may not be secured. When the size of the display extension length (Z) becomes greater than the third length (L3), the electronic device (500) may change the tune code for the first antenna (Main1) to an open code, thereby changing the states of the switches and capacitors inside the aperture tuner. Through this, wireless communication performance for the first antenna (Main1) may be secured.

[0090] When the display extension length (Z) is further extended and the display extension length (Z) is greater than the sum of the first length (L1) and the third length (L3) ((L1+L3) < Z), the electronic device (500) can apply an opening code to each of the first antenna (Main1) using the first conductive portion (510) and the second antenna (Main2) using the second conductive portion (520). For example, the electronic device (500) can maintain the first opening code (A1_Roll_Open) to the first antenna (Main1) and apply the second opening code (A2_Roll_Open) to the second antenna (Main2).

[0091] When the display extension length (Z) becomes greater than the sum of the first length (L1) and the third length (L3) ((L1+L3) < Z), a void that is not filled with the display (505) may be formed around the second conductive portion (520). Due to a change in the conductive structure around the second conductive portion (520), the resonance characteristics of the second antenna (Main2) using the second conductive portion (520) may change. If the second antenna (Main2) maintains the existing tune code, wireless communication performance using the second antenna (Main2) may not be secured. When the display extension length (Z) becomes greater than the sum of the first length (L1) and the third length (L3), the electronic device (500) may change the tune code for the second antenna (Main2) to an open code, thereby changing the states of the switches and capacitors inside the aperture tuner. Through this, wireless communication performance for the second antenna (Main2) can be secured.

[0092] The second frame portion (upper frame) (502) may include a fourth conductive portion (or fourth conductive member) (550), a fifth conductive portion (or fifth conductive member) (560), a third non-conductive member (551), and a fourth non-conductive member (552). The fourth conductive portion (550) and the fifth conductive portion (560) may be separated from each other by the third non-conductive member (551). The fourth conductive portion (550) may have a fourth length (L4). A portion of the second frame portion (upper frame) (502) excluding the fourth conductive portion (550) may have a fifth length (L5). The third antenna (Sub1) may transmit and receive a wireless communication signal using the fourth conductive portion (550).

[0093] When the display extension length (Z) is less than the fifth length (L5) (0 < Z < L5), the electronic device (500) can apply a pre-stored closing code to the third antenna (Sub1) using the fourth conductive portion (550). For example, the electronic device (500) can apply the third closing code (A3_Roll_Close) to the aperture tuner of the third antenna (Sub1).

[0094] When the display extension length (Z) increases and becomes larger than the fifth length (L5), the electronic device (500) can apply a pre-stored opening code to the third antenna (Sub1) using the fourth conductive portion (550). For example, the electronic device (500) can apply the third opening code (A3_Roll_Open) to the aperture tuner of the third antenna (Sub1).

[0095] When the display extension length (Z) becomes greater than the fifth length (L5), a void that is not filled with the display (505) may be formed around the fourth conductive portion (550). Due to the change in the conductive structure around the fourth conductive portion (550), the resonance characteristics of the third antenna (Sub1) using the fourth conductive portion (550) may change. If the third antenna (Sub1) maintains the existing tune code, wireless communication performance using the third antenna (Sub1) may not be secured. When the size of the display extension length (Z) becomes greater than the fifth length (L5), the electronic device (500) may change the tune code for the third antenna (Sub1) to an open code, thereby changing the states of the switches and capacitors inside the aperture tuner. Through this, wireless communication performance for the third antenna (Sub1) may be secured.

[0096]

[0097] FIG. 6 illustrates a change in tune code of multiple antennas according to one embodiment.

[0098] Referring to FIG. 6, the first graph (610) illustrates a batch change of antenna codes in a sliderable / rollable electronic device. That is, the tune codes of all antennas change at a specific expansion distance. In the case of a batch change, the code change occurs equally for all antennas at a specified expansion ratio (e.g., 50%). In this case, it may be difficult to reflect electrical changes or ground (GND) conditions around the conductive portion of each antenna. Alternatively, if the tune code is changed in a more detailed manner than that shown in the first graph (610), the load on the communication circuit may increase, which may reduce wireless communication efficiency.

[0099] The second graph (620) illustrates a case where the tune code of an antenna in a slider / rollable electronic device changes differently depending on the expansion ratio of the display. For example, the tune code of the first antenna (Main1) may change at the first expansion ratio (e.g., 33%). The tune code of the third antenna (Sub1) may change at the second expansion ratio (e.g., 63%). The tune code of the second antenna (Main2) may change at the third expansion ratio (e.g., 75%).

[0100] In a slider / rollable electronic device, two tune codes can be pre-stored for each antenna. The timing of switching between antenna tune codes can be determined based on the length of the conductive portion used by each antenna, the location of the conductive portion, and the extent to which the display expands or contracts. This ensures that antenna performance remains above a certain level regardless of the extent of display expansion, thereby improving the massive data transmission performance of 5G / 6G.

[0101]

[0102] Figure 7 is a flowchart illustrating a wireless communication method according to one embodiment.

[0103] Referring to FIG. 7, at operation 705, a processor (e.g., the processor (120) of FIG. 1) of an electronic device (e.g., the electronic device (101) of FIG. 1, the electronic device (200) of FIGS. 2A and 2B, and the electronic device (500) of FIG. 5) may operate a first antenna and a second antenna with a designated tune code. For example, when the electronic device is in a reduced mode, the processor may apply a pre-stored closing code to each of the first antenna and the second antenna. For another example, when the electronic device is in an expanded mode, the processor may apply a pre-stored opening code to each of the first antenna and the second antenna.

[0104] In operation 710, the processor can detect a reduction or enlargement of a display (e.g., the display module (160) of FIG. 1, the display (250) of FIGS. 2A and 2B, and the display (505) of FIG. 5). The processor can recognize a sliding motion of the housing through a sensor module. Based on the sensing information, the processor can determine an expansion distance of the display.

[0105] At operation 720, the processor may determine whether the zoom in or zoom out distance of the display exceeds (or is greater than) a first threshold. The first threshold may be a value associated with the length of conductive portions forming a side frame of the electronic device.

[0106] In operation 730, if the display's zoom-in or zoom-out distance exceeds a first threshold, the processor may change the tuning code of the first antenna and maintain the tuning code of the second antenna. Depending on the display's zoom-in or zoom-out, the change in the conductive structure around the first antenna may be relatively large, and the change in the conductive structure around the second antenna may be relatively small. The processor may change the tuning code applied to the first antenna to prevent the wireless communication performance of the first antenna from deteriorating.

[0107] According to one embodiment, when the zoom in or zoom out distance of the display returns to below the first threshold after exceeding the first threshold, the tune code of the first antenna can be returned to a previous state (state of operation 705).

[0108] At operation 740, the processor may determine whether the zoom-in or zoom-out distance of the display exceeds (or is greater than) a second threshold. The second threshold may be a value greater than the first threshold, and may be a value associated with the length of conductive portions forming a side frame of the electronic device.

[0109] In operation 750, if the display zoom-in or zoom-out distance exceeds the second threshold, the processor may change the tuning code of the second antenna. As the display zoom-in or zoom-out distance exceeds both the first threshold and the second threshold, the change in the conductive structure around the first and second antennas may be relatively large. The processor may change the tuning codes applied to both the first and second antennas so that the wireless communication performance of the first and second antennas is not degraded.

[0110] According to one embodiment, when the zoom in or out distance of the display returns to below the second threshold after exceeding the second threshold, the tune code of the second antenna can be returned to a previous state (state of operation 730).

[0111] For rollable / slidable electronic devices, antenna performance may vary significantly depending on the level of display expansion. Simply applying two tune codes, one for the closed and one for the unfolded states, like foldable electronic devices, to rollable / slidable electronic devices may result in degraded antenna performance, as the tuning codes are not optimized for the display expansion level.

[0112] Additionally, for rollable / sliderable electronic devices, the method of performing optimization of each tuner multiple times as the display size increases may be difficult to apply to actual products due to computational and processing delays.
