Description

Technical Field

[0001] The present disclosure relates to an electronic device having an antenna device. Background Art

[0002] The development of electronic information and communication technologies has integrated various functions into a single electronic device. For example, a smart phone combines the functions of a sound player, an imaging device, a scheduler, and a communication function, and in addition, more different functions can be realized by installing applications thereon.

[0003] A user of an electronic device can search, filter, and obtain more information by accessing a network, rather than simply using the functions or information (e.g., applications) of the electronic device. Direct access to a network (e.g., wired communication) enables the establishment of fast and stable communication, but its availability may be limited to a fixed location or space. Wireless network access is less restricted by location or space and provides a speed and stability level close to that of direct network access, and is expected to establish communication faster and more stably than direct network access.

[0004] With the popularization of smart phones or other personal / portable communication devices, the user's demand for portability and ease of use is increasing. For example, a foldable or rollable electronic device may be easy to carry and provide an enhanced multimedia environment with a larger screen.

[0005] The above information is provided only as background information to help understand the present disclosure. No determination has been made, nor is any assertion made, as to whether any of the above is applicable prior art to the present disclosure. Summary of the Invention

[0006] Technical Problem

[0007] In a compact electronic device, it may be difficult to ensure a communication environment for different frequency bands. For example, it is necessary to provide an independent operating environment (e.g., sufficient space) for each antenna, but this may be impossible in such a small electronic device. A foldable or rollable electronic device has a further reduced structure or space for placing antennas. The housing is thinned to obtain greater flexibility, so it is impossible to provide a sufficiently large space for arranging antennas. In an embodiment, a foldable or rollable electronic device may experience a change in the operating environment of an antenna when it is curled or folded. For example, in a folded or curled state, the arrangement of the structures around the antenna may change, and the operating performance of the antenna also changes.

[0008] An aspect of the present disclosure is to at least solve the above problems and / or disadvantages and at least provide the following advantages. Accordingly, an aspect of the present disclosure is to provide an electronic device having an antenna device that can provide stable operating performance even when the structure is folded or curled.

[0009] Another aspect of the present disclosure is to provide an electronic device having an antenna device that can be easily provided in a thin and compact structure and provides stable operating performance.

[0010] Another aspect of the present disclosure is to provide an electronic device having a plurality of first and second connection members for electrically connecting a switching unit disposed in a structure and each radiating conductor (e.g., an antenna).

[0011] Another aspect of the present disclosure is to provide an electronic device having an antenna device that provides stable operating performance according to a hand grip on the structure in a folded state or an unfolded state of the structure.

[0012] Additional aspects will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the presented embodiments.

[0017] Advantageous Effects

[0018] According to various embodiments, in an electronic device having an antenna device, at least a part of the first side surface member and the second side surface member of the electronic device may be formed of a radiation conductor provided as an antenna. Accordingly, stable operating performance (e.g., radiation efficiency) may be achieved in the unfolded state of the electronic device.

As another example, the radiation conductors may implement at least a part of the first side surface member and the second side surface member as an antenna, such that it may be more easily placed even in a thin, light, and compact structure.

[0019] According to various embodiments, in the unfolded state or the folded state of the first housing structure and the second housing structure among the plurality of housing and hinge structures supporting a display, a plurality of first and second connection members (e.g., coaxial cables, flexible printed circuit boards (FPCBs), microstrip lines, or strip lines) for connecting at least one of the first to fourth radiation conductors included in the electronic device to the switching unit are formed, providing a better electrical connection between the switching unit and at least one of the first to fourth radiation conductors, thereby enhancing the antenna function of at least one of the first to fourth radiation conductors.

[0076] The communication module 190 may support establishing a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device 101 and an external electronic device (e.g., the external electronic device 102, the external electronic device 104, or the server 108), and perform communication via the established communication channel. The communication module 190 may include one or more communication processors capable of operating independently of the processor 120 (e.g., an application processor (AP)), and support direct (e.g., wired) communication or wireless communication. According to an 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 (PLC) module). A corresponding one of these communication modules may 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 Association (IrDA)) or a second network 199 (e.g., a long-range communication network, such as a cellular network, the Internet, or a computer network (e.g., LAN or wide area network (WAN))). These various types of communication modules may be implemented as a single component (e.g., a single chip), or these various types of communication modules may be implemented as multiple separate components (e.g., multiple chips). The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network (such as the first network 198 or the second network 199) using user information (e.g., an international mobile subscriber identity (IMSI)) stored in the user identification module 196.

[0077] The antenna module 197 may transmit signals or power to the outside of the electronic device 101 (e.g., an external electronic device) or receive signals or power from the outside of the electronic device 101 (e.g., an external electronic device). According to an embodiment, the antenna module may include an antenna, and the antenna may include a radiator formed of a conductor or a conductive pattern formed on a substrate (e.g., a printed circuit board (PCB)). According to an embodiment, the antenna module 197 may include a plurality of antennas. In this case, for example, the communication module 190 may select at least one antenna suitable for a communication scheme to be used in a communication network (such as the first network 198 or the second network 199) from among the plurality of antennas. Subsequently, signals or power may be transmitted or received between the communication module 190 and an external electronic device via the selected at least one antenna. According to an embodiment, additional components (e.g., a radio frequency integrated circuit (RFIC)) other than the radiator may be additionally formed as part of the antenna module 197.

[0078] At least some of the above components may be interconnected via an inter-peripheral communication scheme (e.g., a bus, a general-purpose input / output (GPIO), a serial peripheral interface (SPI), or a mobile industry processor interface (MIPI)) and communicatively transmit signals (e.g., commands or data) therebetween.

[0079] According to an 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 first and second external electronic devices 102 and 104 may be a device of the same type as the electronic device 101 or a device of a different type from the electronic device 101. According to an embodiment, all or some of the operations running on the electronic device 101 may be run on one or more of the external electronic device 102, the external electronic device 104, or the server 108. For example, if the electronic device 101 is to automatically perform a function or service or is to perform a function or service in response to a request from a user or another device, the electronic device 101 may request one or more of the external electronic devices to perform at least part of the function or service instead of running the function or service, or in addition to running the function or service, the electronic device 101 may also request one or more of the external electronic devices to perform at least part of the function or service. The one or more external electronic devices that receive the request may perform the requested at least part of the function or service, or perform additional functions or additional services related to the request, and transmit the result of the performance to the electronic device 101. The electronic device 101 may provide the result as at least part of a reply to the request with or without further processing of the result. To this end, for example, cloud computing technology, distributed computing technology, or client-server computing technology may be used.

[0080] Figure 2 is a view showing an electronic device 200 in an unfolded state according to an embodiment of the present disclosure.

[0081] Figure 3 is a view showing an electronic device 200 in a folded state according to an embodiment of the present disclosure. Figure 2 of the electronic device 200.

[0082] Figure 2 and Figure 3 The electronic device 200 of may be at least partially similar to the Figure 1 electronic device 101, or may include other features.

[0083] Referring to Figure 2 , the electronic device 200 may include: a pair of housing structures 210 and 220, via a hinge structure (e.g., Figure 4The hinge structure 264) is coupled together to be rotatable to fold with respect to each other; a hinge cover 265 that covers a foldable portion of the pair of housing structures 210 and 220; and a display 230 (e.g., a flexible display or a foldable display) disposed in a space formed by the pair of housing structures 210 and 220. According to an embodiment, the hinge cover 265 may be a part of the hinge structure 264. According to an embodiment, the electronic device 200 may include a foldable housing that is rotatably coupled to the pair of housing structures 210 and 220 from a position where the pair of housing structures 210 and 220 are folded to face each other to a position where they are placed side by side. In the present disclosure, the surface on which the display 230 is located may be defined as the "front surface" of the electronic device 200, and the opposite surface thereof may be defined as the "rear surface" of the electronic device 200. The surface surrounding the space between the front surface and the rear surface may be defined as the "side surface" of the electronic device 200.

[0084] According to an embodiment, the pair of housing structures 210 and 220 may include a first housing structure 210 having a sensor area 231d, a second housing structure 220, a first rear cover 240, and a second rear cover 250. The pair of housing structures 210 and 220 of the electronic device 200 are not limited to Figure 2 and Figure 3 the shapes and couplings shown, but may be implemented in other shapes or via combinations and / or couplings of other components. For example, the first housing structure 210 and the first rear cover 240 may be integrally formed with each other, and the second housing structure 220 and the second rear cover 250 may be integrally formed with each other.

[0085] According to an embodiment, the first housing structure 210 and the second housing structure 220 may be located on opposite sides of a first axis (e.g., a folding axis A), and they may be overall symmetric with respect to each other in shape with respect to the folding axis A. According to an embodiment, the first housing structure 210 and the second housing structure 220 may rotate about the hinge structure 264 or the hinge cover 265 with respect to different folding axes. For example, the first housing structure 210 and the second housing structure 220 may each be rotatably coupled to the hinge structure 264 or the hinge cover 265, and the first housing structure 210 and the second housing structure 220 may rotate from a position where they are folded together to a position where they are inclined with respect to each other or placed side by side about the folding axis A or a different folding axis.

[0086] As used herein, when A and B are positioned or extended side by side, this may mean that A and B are positioned at least partially adjacent to each other or at least partially parallel to each other. According to an embodiment, when A and B are arranged (or disposed) side by side, this may mean that A and B are arranged (or disposed) to face the same direction or directions parallel to each other. In the following description, although example phrases "side by side" and "parallel to each other" may be used to describe corresponding structures, the shapes or arrangements of these structures can be easily understood from the drawings.

[0087] According to an embodiment, the first housing structure 210 and the second housing structure 220 may form different angles or distances depending on whether the electronic device 200 is in an unfolded state (or flat state, or open state), a folded state (or folded condition), or a state in between. According to an embodiment, the first housing structure 210 and the second housing structure 220 may be symmetric in shape except that the first housing structure 210 further includes a sensor area 231d where various sensors are arranged. Alternatively, the sensor area 231d may be provided in at least a portion of the second housing structure 220 instead of the first housing structure 210, or additional sensor areas may be included in the second housing structure 220.

[0088] According to an embodiment, in the unfolded state of the electronic device 200, the first housing structure 210 may be connected to a hinge structure (e.g., Figure 4 hinge structure 264) and may include a first surface 211 arranged to face the front surface of the electronic device 200, a second surface 212 facing away from the first surface 211, and a first side surface member 213 surrounding at least a portion of the space between the first surface 211 and the second surface 212. According to an embodiment, the first side surface member 213 may include a first side surface 213a arranged parallel to the folding axis A, a second side surface 213b extending from one end of the first side surface 213a in a direction perpendicular to the folding axis A, and a third side surface 213c extending from the other end of the first side surface 213a in a direction perpendicular to the folding axis A. As used herein, the terms "perpendicular" or "parallel" may be used interchangeably with "partially perpendicular" or "partially parallel". In some embodiments, "parallel" or "perpendicular" may also mean "tilted within an angular range of 10 degrees".

[0089] According to an embodiment, the second housing structure 220 may be connected to a hinge structure (e.g., Figure 4hinge structure 264), and in the unfolded state of the electronic device 200, the second housing structure 220 may include a third surface 221 disposed to face the front surface of the electronic device 200, a fourth surface 222 facing away from the third surface 221, and a second side surface member 223 surrounding at least a portion of the space between the third surface 221 and the fourth surface 222. According to an embodiment, the second side surface member 223 may include a fourth side surface 223a disposed parallel to the folding axis A, a fifth side surface 223b extending from one end of the fourth side surface 223a in a direction perpendicular to the folding axis A, and a sixth side surface 223c extending from the other end of the fourth side surface 223a in a direction perpendicular to the folding axis A. According to an embodiment, in the folded state, the third surface 221 may be disposed to face the first surface 211. According to an embodiment, the second side surface member 223 may be formed of substantially the same shape or material as the first side surface member 213, although they may be partially different in their specific shapes.

[0090] According to an embodiment, the electronic device 200 may include a recess 201 to accommodate the display 230 through a combined structural shape of the first housing structure 210 and the second housing structure 220. The recess 201 may have substantially the same dimensions as the display 230. According to an embodiment, due to the sensor region 231d, the recess 201 may have two or more different widths in a direction perpendicular to the folding axis A. For example, the recess 201 may have a first width W1 between a first portion 220a of the second housing structure 220 parallel to the folding axis A and a first portion 210a of the first housing structure 210 formed at the edge of the sensor region 231d, and a second width W2 formed by a second portion 220b of the second housing structure 210 and a second portion 210b of the first housing structure 210 parallel to the folding axis A and not corresponding to the sensor region 231d. In this case, the second width W2 may be greater than the first width W1. For example, the recess 201 may have a first width W1 formed between a first portion 210a of the first housing structure 210 and a first portion 220a of the second housing structure 220 that are asymmetrical in shape with each other, and a second width W1 formed between a second portion 210b of the first housing structure 210 and a second portion 220b of the second housing structure 220 that are symmetrical in shape with each other. According to an embodiment, the first portion 210a and the second portion 210b of the first housing structure 210 may be formed at different distances from the folding axis A. The width of the recess 201 is not limited thereto. According to an embodiment, depending on the shape of the sensor region 231d or the asymmetrical shape portions of the first housing structure 210 and the second housing structure 220, the recess 201 may have two or more different widths.

[0091] According to an embodiment, the first housing structure 210 and the second housing structure 220 may be at least partially formed of a metal or non-metal material having a stiffness selected to support the display 230. According to an embodiment, the first housing structure 210 and the second housing structure 220 may at least partially include a conductive material. When the first housing structure 210 and the second housing structure 220 include a conductive material, the electronic device 200 may transmit / receive radio waves via the conductive portions of the first housing structure 210 and the second housing structure 220. For example, a processor (e.g., Figure 1 the processor 120) or a communication module (e.g., the communication module 190) of the electronic device 200 may use a part of the first housing structure 210 and the second housing structure 220 to perform wireless communication.

[0092] According to an embodiment, the sensor area 231d may be formed adjacent to one corner of the first housing structure 210 and have a predetermined area. However, the placement, shape, or size of the sensor area 231d is not limited to that shown in the figure. For example, according to an embodiment, the sensor area 231d may be provided in a different corner of the first housing structure 210 or in any area between the top corner and the bottom corner. According to an embodiment, the sensor area 231d may be provided in at least one area of the second housing structure 220. According to an embodiment, the sensor area 231d may be provided to extend to the first housing structure 210 and the second housing structure 220. According to an embodiment, the electronic device 200 may include components exposed from its front surface through the sensor area 231d or one or more openings prepared in the sensor area 231d, and various functions may be performed through these components. Components arranged in the sensor area 231d may include, for example, a front camera device (e.g., Figure 1 the camera module 180), a receiver (e.g., Figure 1 the audio module 170), a proximity sensor, an illuminance sensor, an iris recognition sensor, an ultrasonic sensor (e.g., Figure 1 the sensor module 176), or at least one of an indicator.

[0093] According to an embodiment, the first rear cover 240 may be disposed on the second surface 212 of the first housing structure 210 and may have a substantially rectangular perimeter. According to an embodiment, at least a portion of the perimeter of the first rear cover 240 may be surrounded by the first housing structure 210. Similarly, the second rear cover 250 may be disposed on the fourth surface 222 of the second housing structure 220, and at least a portion of its perimeter may be surrounded by the second housing structure 220.

[0094] In the illustrated embodiment, the first rear cover 240 and the second rear cover 250 may be substantially symmetric with respect to the folding axis A in shape. According to an embodiment, the first rear cover 240 and the second rear cover 250 may have various other different shapes. According to an embodiment, the first rear cover 240 may be integrally formed with the first housing structure 210, and the second rear cover 250 may be integrally formed with the second housing structure 220.

[0095] According to an embodiment, the combined structure of the first rear cover 240, the second rear cover 250, the first housing structure 210, and the second housing structure 220 may provide a space in which various components (e.g., a printed circuit board, an antenna module, a sensor module, or a battery) of the electronic device 200 may be disposed. According to an embodiment, one or more components may be disposed on or visually exposed through the rear surface of the electronic device 200. For example, one or more components or sensors may be visually exposed through the first rear surface area 241 of the first rear cover 240. According to an embodiment, the sensor may include a proximity sensor, a rear camera device, and / or a flash. According to an embodiment, the sub-display 252 may be at least visually exposed through the second rear surface area 251 of the second rear cover 250.

[0096] The display 230 may be disposed in the space formed by the pair of housing structures 210 and 220. For example, the display 230 may be seated in a recess (e.g., Figure 2 the recess 201) formed by the pair of housing structures 210 and 220, and the display 230 may be disposed to substantially occupy most of the front surface of the electronic device 200. For example, the front surface of the electronic device 200 may include the display 230, a partial area (e.g., an edge area) of the first housing structure 210 adjacent to the display 230, and a partial area (e.g., an edge area) of the second housing structure 220. According to an embodiment, the rear surface of the electronic device 200 may include the first rear cover 240, a partial area (e.g., an edge area) of the first housing structure 210 adjacent to the first rear cover 240, the second rear cover 250, and a partial area (e.g., an edge area) of the second housing structure 220 adjacent to the second rear cover 250.

[0097] According to an embodiment, the display 230 may refer to a display at least a part of which can be transformed into a flat or curved shape. According to an embodiment, the display 230 may include a folding region 231c, a first region 231a (e.g., the right hand side region of the folding region 231c) provided on one side of the folding region 231c, and a second region 231b (e.g., the left hand side region of the folding region 231c) provided on the opposite side of the folding region 231c. For example, the first region 231a may be provided on the first surface 211 of the first housing structure 210, and the second region 231b may be provided on the third surface 221 of the second housing structure 220. For example, the display 230 may extend from the first surface 211 to the third surface through Figure 3 the hinge structure 264, and at least the region corresponding to the hinge structure (e.g., the folding region 231c) may be a flexible region that can be changed from flat to curved.

[0098] According to an embodiment, the division of the display 230 is merely an example, and the display 230 may be divided into a plurality (e.g., four or more or two) of regions depending on the structure or function of the display 230. As an example, in Figure 2 the illustrated embodiment, the folding region 231c may extend on a vertical axis (e.g., Figure 4 the Y axis) parallel to the folding axis A, and the regions of the display 230 may be divided by the folding region 231c or the folding axis A. In another embodiment, the regions of the display 230 may be divided by another folding part (e.g., a folding region parallel to the horizontal axis (e.g., Figure 4 the X axis)) or another folding axis (e.g., a folding axis parallel to Figure 4 the X axis). The above region division is only a physical division by a pair of housing structures 210 and 220 and a hinge structure (e.g., Figure 4 the hinge structure 264), and basically, the display 230 may display a single complete screen via the pair of housing structures 210 and 220 and the hinge structure (e.g., Figure 4 the hinge structure 264).

[0099] According to an embodiment, the first region 231a and the second region 231b may be overall symmetric in shape with respect to the folding region 231c. However, different from the second region 231b, the first region 231a may include a notch region (e.g., Figure 4 the notch region 233) providing a sensor region 231d, and in the remaining regions, is symmetric in shape with the second region 231b. For example, the first region 231a and the second region 231b may include symmetric parts and asymmetric parts.

[0100] Referring to Figure 3, a hinge cover 265 may be disposed between the first housing structure 210 and the second housing structure 220 to hide internal components (e.g., Figure 4 the hinge structure 264). For simplicity of description, the hinge cover 265 is provided separately from the hinge structure 264. However, as described above, the hinge cover 265 may be part of the hinge structure 264 and may partially form the appearance of the electronic device 200. According to an embodiment, depending on the operating state of the electronic device 200 (e.g., unfolded state or folded state), the hinge cover 265 may be hidden by a part of the first housing structure 210 and the second housing structure 220 or may be exposed to the outside.

[0101] As an example, as Figure 2 shown, in the unfolded state of the electronic device 200, the hinge cover 265 may be hidden by the first housing structure 210 and the second housing structure 220 and thus not be exposed. As another example, as Figure 3 shown, in the folded state (e.g., fully folded state) of the electronic device 200, the hinge cover 265 may be exposed between the first housing structure 210 and the second housing structure 220. As another example, in an intermediate state of the electronic device 200 in which the first housing structure 210 and the second housing structure 220 are folded at a certain angle, a part of the hinge cover 265 may be exposed to the outside of the electronic device 200 between the first housing structure 210 and the second housing structure 220. In this case, the exposed area may be smaller than when the electronic device 200 is in the folded state. According to an embodiment, the hinge cover 265 may include a curved surface.

[0102] Described below is the operation of each region of the first housing structure 210, the second housing structure 220, and the display 230 depending on the operating state (e.g., unfolded state and folded state) of the electronic device 200.

[0103] According to an embodiment, when the electronic device 200 is in the unfolded state (e.g., in the state as Figure 2 shown), the angle between the first housing structure 210 and the second housing structure 220 is 180 degrees, and the first region 231a and the second region 231b of the display may be placed to face the same direction (e.g., directions parallel to each other), e.g., to display a screen image in the same direction. The folding region 231c may be flush with the first region 231a and the second region 231b.

[0104] According to an embodiment, when the electronic device 200 is in the folded state (e.g., in the state as Figure 3 shown), the first housing structure 210 and the second housing structure 220 may face each other. For example, in the folded state of the electronic device 200 (e.g., in the state as Figure 3In the state shown, the first region 231a and the second region 231b of the display 230 may be presented as facing each other, forming a relatively small angle therebetween (e.g., from 0 degrees to 10 degrees). In the folded state of the electronic device 200 (e.g., as shown in Figure 3 the state shown), the folding region 231c may at least partially form a curved surface having a predetermined curvature.

[0105] According to an embodiment, when the electronic device 200 is in an intermediate state, the first housing structure 210 and the second housing structure 220 may form an angle therebetween. For example, in the intermediate state, the first region 231a and the second region 231b of the display 230 may form an angle that is larger than the angle when it is in the folded state and smaller than the angle when it is in the unfolded state. The folding region 231c may at least partially have a curved surface having a predetermined curvature, and in this case, the curvature may be smaller than the curvature when it is in the folded state.

[0106] Figure 4 is an exploded perspective view showing an electronic device 200 according to an embodiment of the present disclosure.

[0107] Referring to Figure 4 , the electronic device 200 may include a display 230, a support member assembly 260, at least one printed circuit board 270, a first housing structure 210, a second housing structure 220, a first rear cover 240, and a second rear cover 250. In the present disclosure, the display 230 may be used interchangeably with a display module or a display assembly.

[0108] The display 230 may include a display panel 231 (e.g., a flexible display panel) and one or more boards 232 or layers seated on the display panel 231. According to an embodiment, the board 232 may be disposed between the display panel 231 and the support member assembly 260. The display panel 231 may be disposed on at least a part of the surface (e.g., Figure 4 the surface facing the Z-axis) of the board 232. The board 232 may have a shape corresponding to the display panel 231. For example, a part of the board 232 may have a shape corresponding to the shape of the notch region 233 of the display panel 231.

[0109] The support member assembly 260 may include a first support member 261, a second support member 262, a hinge structure 264 provided with the first support member 261 and the second support member 262, a hinge cover 265 covering the hinge structure 264 when viewed from the outside, and a wiring member (e.g., a flexible printed circuit board (FPCB)) spanning the first support member 261 and the second support member 262.

[0110] According to an embodiment, the support member assembly 260 may be provided with a plate 232 and at least one printed circuit board 270. As an example, the first support member 261 may be provided with a first printed circuit board 271 and a first region 231a of the display 230. The second support member 262 may be provided with a second printed circuit board 272 and a second region 131b of the display 230.

[0111] According to an embodiment, the wiring member 263 and the hinge structure 264 may be at least partially disposed inside the support member assembly 260. The wiring member 263 may be disposed in a direction (e.g., the X-axis direction) across the first support member 261 and the second support member 262. The wiring member 263 may be disposed in a direction (e.g., the X-axis direction) perpendicular to the folding axis (e.g., Figure 1 the folding axis A or the Y-axis).

[0112] As described above, the at least one printed circuit board 270 may include a first printed circuit board 271 disposed on the first support member 261 and a second printed circuit board 272 disposed on the second support member 262. The first printed circuit board 271 and the second printed circuit board 272 may be disposed inside a space formed by the support member assembly 260, the first housing structure 210, the second housing structure 220, the first rear cover 240, and the second rear cover 250. Components (e.g., Figure 1 at least one of the components) for implementing various functions of the electronic device 200 may be mounted on the first printed circuit board 271 and the second printed circuit board 272.

[0113] According to an embodiment, the first housing structure 210 and the second housing structure 220 may be assembled together to be coupled to both sides of the support member assembly 260, and the display 230 is coupled to the support member assembly 260. The first housing structure 210 and the second housing structure 220 may be slidably coupled to two opposite sides of the support member assembly 260, e.g., the first support member 261 and the second support member 262, respectively.

[0114] According to an embodiment, the first housing structure 210 may include a first rotary support surface 214 (e.g., Figure 5 the fourth side surface portion 514 as described below), and the second housing structure 520 may include a second rotary support surface 224 corresponding to the first rotary support surface 214 (e.g., Figure 5 the eighth side surface 523 as described below). The first rotary support surface 214 and the second rotary support surface 224 may include curved surfaces corresponding to the curved surfaces included in the hinge cover 265.

[0115] According to an embodiment, when the electronic device 200 is in the unfolded state (e.g., as Figure 2When in the state shown, the first rotary support surface 214 and the second rotary support surface 224 may cover the hinge cover 265, allowing the hinge cover 265 to be not exposed or minimally exposed to the rear surface of the electronic device 200. According to an embodiment, when the electronic device 200 is in a folded state (e.g., in the state shown as Figure 3 ), the first rotary support surface 214 and the second rotary support surface 224 may rotate along the curved surface of the hinge cover 265, maximizing the exposure of the hinge cover 265 to the rear surface of the electronic device 200.

[0116] In the above description, the ordinal numbers in the first housing structure 210, the second housing structure 220, the first side surface member 213, and the second side surface member 223 are only used to distinguish components, and it should be noted that the scope of the present disclosure is not limited by the use of ordinal numbers. For example, although the sensor area 231d is formed in the first housing structure 210 in the above example, the sensor area 231d may be formed in the second housing structure 220 or in each of the first housing structure 210 and the second housing structure 220. According to an embodiment, although the first rear surface area 241 and the sub-display 252 are respectively provided in the first rear cover 240 and the second rear cover 250, both the first rear surface area 241 for placing, for example, a sensor and the sub-display 252 for outputting a screen image may be provided in the first rear cover 240 or the second rear cover 250.

[0117] According to an embodiment, in the plurality of housing structures 210 and 220 and the hinge structure 264 that support one display 230, an antenna device may be provided in the first housing structure or the second housing structure. An example configuration in which the antenna device is provided in the second housing structure will be described below. However, as described above, the embodiments of the present disclosure are not limited thereto, and it should be noted that, according to an embodiment, the antenna device may be provided in the first housing structure of the electronic device.

[0118] Figure 5 is a view showing the configuration of the (multiple) side surface members 501 and 502 in an electronic device (e.g., Figure 2 the electronic device 200) according to an embodiment of the present disclosure.

[0119] Referring to Figure 5 , the side surface members (e.g., Figure 4 the first side surface member 213 and the second side surface member 223) may include a first side surface member 501 provided as a part of the first housing structure 210 provided as Figure 2 and a second side surface member 502 provided as a part of the second housing structure 220. According to an embodiment, the first side surface member 501 and the second side surface member 502 may be shaped to surround the housing structure (e.g., Figure 2The frame of the internal space of the first housing structure 210 and the second housing structure 220).

[0120] According to an embodiment, the first side surface member 501 and the second side surface member 502 may have substantially the same structure, except for slight differences in shape. According to an embodiment, the first side surface member 501 and the second side surface member 502 may at least partially include a conductive material. For example, Figure 5 Generally shows the conductive material portions of the first side surface member 501 and the second side surface member 502. The first side surface member 501 and the second side surface member 502 may include a non-conductive material, such as an insulating material, allowing their final shape to be a closed curve or loop.

[0121] According to an embodiment, the first side surface member 501 may include a first side surface portion 511, a second side surface portion 512, a third side surface portion 513, a fourth side surface portion 514, and / or a fifth side surface portion 515. According to an embodiment, the first to fifth side surface portions 511, 512, 513, 514, and 515 may also be referred to as "the first to fifth side surface portion local frames". According to an embodiment, the first side surface portion 511 may be disposed parallel to the folding axis A. The second side surface portion 512 may be disposed at a distance from one end (e.g., the top) of the first side surface portion 511 in a direction intersecting or substantially perpendicular to the folding region A. The third side surface portion 513 may be disposed at a distance from the opposite end (e.g., the bottom) of the first side surface portion 511 parallel to the folding region A.

[0122] The fourth side surface portion 514 may be disposed adjacent to one end of the third side surface portion 513 and may be disposed at a distance from the third side surface portion 513 and may extend to the folding region A in an intersecting direction or in a substantially perpendicular direction. The fifth side surface portion 515 may extend substantially parallel to the folding region A or the first side surface portion 511. One end of the fifth side surface portion 515 is disposed at a distance from one end of the second side surface portion 512, and the other end of the fifth side surface portion 515 is disposed at a distance from one end of the fourth side surface portion 514. According to an embodiment, the fifth side surface portion 515 may be disposed adjacent to a hinge structure or a hinge cover (e.g., Figure 4 the hinge structure 264 or the hinge cover 265), and may extend substantially parallel to the hinge structure 264 or the hinge cover 265 along the folding region A.

[0123] According to an embodiment, the first side surface member 501 may include (a plurality of) slits 516a, 516b, 516c, 516d, and 516e that at least partially separate conductive material portions. According to an embodiment, the (a plurality of) slits 516a, 516b, 516c, 516d, and 516e may be filled with a non-conductive material, which may be referred to as a "non-conductive portion" or a "non-conductive material portion" as needed. A structure formed of an insulating material may be formed in at least a portion of the region surrounded by the first to fifth side surface portions 511, 512, 513, 514, and 515. According to an embodiment, the (a plurality of) slits 516a, 516b, 516c, 516d, and 516e may be filled with an insulating material. For example, the first side surface member 501 may include a non-conductive portion, a non-conductive material portion, or an insulating material portion that insulates some conductive material portions from other conductive material portions.

[0124] According to an embodiment, the first slit 516a may be formed between one end of the first side surface portion 511 and the second side surface portion 512, and the second slit 516b may be formed between the second side surface portion 512 and the fifth side surface portion 515. The third slit 516c may be formed between the opposite end of the first side surface portion 511 and the third side surface portion 513. The fourth slit 516d may be formed between the third side surface portion 513 and the fourth side surface portion 514, and the fifth slit 516e may be formed between the fourth side surface portion 514 and the fifth side surface portion 515.

[0125] At least a portion of the second side surface portion 512, the third side surface portion 513, and the fourth side surface portion 514 may be formed of a conductive material. For example, at least a portion of the second side surface portion 512, the third side surface portion 513, and / or the fourth side surface portion 514 may be formed of a radiation conductor. According to an embodiment, the second side surface portion 512, the third side surface portion 513, and / or the fourth side surface portion 514 may be used as an antenna radiator (e.g., a radiation conductor) of an electronic device (e.g., Figure 2 the electronic device 200). For example, a processor (e.g., Figure 1 the processor 120) or a communication module (e.g., the communication module 190) of the electronic device 200 may perform wireless communication using a portion of the second side surface portion 512, a portion of the third side surface portion 513, and / or a portion of the fourth side surface portion 514.

[0126] According to an embodiment, a portion of the first side surface portion 511 (or the fifth side surface portion 515) may be electrically connected to a printed circuit board (e.g., Figure 4The first printed circuit board 271) is used as a radiation conductor. For example, the power supply portion formed in the first side surface portion 511 can be electrically connected to the printed circuit board (e.g., Figure 4 The first printed circuit board 271), and the ground portion formed at other positions of the first side surface portion 511 can be connected to the printed circuit board (e.g., Figure 4 The first printed circuit board 271). The conductive material portion of the first side surface portion 511 can form a part of the antenna between the position connecting the power supply portion and the position connecting the ground portion.

[0127] According to an embodiment, the third side surface portion 513 can include a first portion 513a and a second portion 513b. For example, the first portion 513a can be formed to have a first length L1 along a direction parallel to the first axis (e.g., Figure 5 The folding region A). The second portion 513b can be connected to the first portion 513a and formed to be curved. The second portion 513b can be formed to have a second length L2 along a direction intersecting the first axis (e.g., Figure 5 The folding region A).

[0128] According to an embodiment, the third slit 516c can be formed between the first side surface portion 511 and the third side surface portion 513.

[0129] According to an embodiment, since the third slit 516c is formed at a position of the first length L1 (which is a distance D1 of not less than 30 mm and not more than 50 mm (e.g., 40 mm) from the second portion 513b of the third side surface portion 513), it can operate as a radiation conductor (e.g., the third side surface portion 513) having the radiation performance required for the electronic device (e.g., Figure 2 The electronic device 200).

[0130] According to an embodiment, refer to the following Fig.13 or Fig.14 The radiation characteristics depending on the position of the third slit 516c are described in more detail. The above values regarding the position of the third slit 516c are applicable to the case where the width of the second side surface member 502 (e.g., along Figure 4Example values of the electronic device having a length in the X-axis direction) of 100 mm or less are given, but it should be noted that the embodiments of the present disclosure are not limited thereto. For example, considering the resonant frequency to be formed using the radiation conductor or the size of the electronic device to be actually manufactured, the third slit 516c may be formed at a position different from the position of the example value. For example, the third slit 516c may be formed at a position of the first length L1 (which is a distance D1 not less than 30 mm and not greater than 50 mm (e.g., 40 mm) from the outside of the second part 513b of the third side surface portion 513), so as to reduce the deterioration of the radiation performance of the radiation conductor (e.g., the third side surface portion 513) and the deterioration of the radiation performance of the radiation conductor (e.g., the third side surface portion 513) due to the influence of the user's body when the user makes a call with the electronic device (e.g., Figure 2 the electronic device 200). In this way, the third slit 516c can enhance the radiation performance of the radiation conductor (e.g., the third side surface portion 513).

[0131] According to an embodiment, as described above in connection with Figure 5 the first length L1 of the third side surface portion 513 may be a length between 30 mm and 50 mm (e.g., 40 mm) along a direction parallel to the first axis (e.g., Figure 5 the folding region A), and the second length L2 of the third side surface portion 513 may be a length between 8.6 mm and 28.6 mm (e.g., 18.6 mm) along a direction intersecting the first axis (e.g., Figure 5 the folding region A).

[0132] According to an embodiment, allowing the first length L1 to be greater than the second length L2 can minimize the deterioration of the radiation performance of the radiation conductor (e.g., the third side surface portion 513) and thus enhance the radiation performance of the radiation conductor (e.g., the third side surface portion 513).

[0133] According to an embodiment, the first length L1 may be formed to be the same as the second length L2. When the electronic device 200 is folded, the eighth side surface portion 523 may be positioned adjacent to the third side surface portion 513. The eighth side surface portion 523 may include a third part 523a and a fourth part 523b. When viewed from above the first rear cover (e.g., Figure 2 the first rear cover 240), the third slit 516c may be formed to overlap with the eighth slit 526c, and the fourth slit 516d may be formed to overlap with the ninth slit 526d. Therefore, among the plurality of housing structures 210 and 220 and the hinge structure (e.g., Figure 4 supporting one display (e.g., Figure 4In the hinge structure 264), when the electronic device 200 is folded, the end of the third side surface portion 513 and the end of the eighth side surface portion 523 can be joined together, thereby reducing the deterioration of the radiation performance of the radiation conductors (e.g., the third side surface portion 513 and the eighth side surface portion 523).

[0134] As described above, the ordinal numbers are only used here to distinguish between components, and the embodiments of the present disclosure are not limited thereto. For example, in other embodiments, the first side surface member 501 may be referred to as the "second side surface member", and the fifth side surface portion 515 may be referred to as the "first side surface portion 511". For example, although ordinal numbers are used to distinguish between some components, this is only for simplicity, and various embodiments of the present disclosure should be understood by the arrangement and connection of the relevant components.

[0135] Refer to the following Figure 6 and Figure 7 to describe in more detail an example configuration of an antenna device (e.g., Figure 6 500) using the structure of the above-mentioned (multiple) side surface members. Figure 6 and Figure 7 The configurations shown in and can be regarded as an example in which a conductive material portion insulated from other conductive material portions by the above-mentioned slit is configured as a radiation conductor. In another embodiment, as described above, a part of another conductive material portion (e.g., the first side surface portion 511 or the sixth side surface portion 521, which is not shown in Figure 6 and Figure 7 can be used to form the antenna device. Alternatively, the third side surface portion 513 or the eighth side surface portion 523 can also be partially used as a radiation conductor. In the following embodiments, components that are the same as or easily understood from the description of the above embodiments are represented by the same or different reference numerals, and their detailed descriptions can be omitted.

[0136] Figure 6 and Figure 7 are views showing the configuration of an antenna device 500 in an electronic device (e.g., Figure 1 the electronic device 200) according to various embodiments of the present disclosure.

[0137] Figure 6 and Figure 7 are Figure 5 an enlarged view of part B of.

[0138] Refer to Figure 6 and Figure 7, the antenna device 500 may include: a first conductive material portion that is part of the first side surface portion 511 (e.g., a part of the first side surface portion 511); a first conductive material portion that is part of the second side surface portion 512 (e.g., the second side surface portion 512); a first conductive material portion that is part of the third side surface portion 513 (e.g., a part of the third side surface portion 513); a first conductive material portion that is part of the fourth side surface portion 514 (e.g., the fourth side surface portion 514); and a first conductive material portion that is part of the fifth side surface portion 515 (e.g., the fifth side surface portion 515).

[0139] According to an embodiment, at least a part of the first conductive material portion forming the first side surface portion 511 may be provided as a radiation conductor, at least a part of the first conductive material portion forming the second side surface portion 512 may be provided as a radiation conductor, at least a part of the first conductive material portion forming the third side surface portion 513 may be provided as a radiation conductor, at least a part of the first conductive material portion forming the fourth side surface portion 514 may be provided as a radiation conductor, and at least a part of the first conductive material portion forming the fifth side surface portion 515 may be provided as a radiation conductor. For example, a fourth slit 516d may be formed between the third side surface portion 513 and the fourth side surface portion 514, and the fourth slit 516d may separate the third side surface portion 513 and the fourth side surface portion 514 from each other.

[0140] According to an embodiment, the third slit 516c, the fourth slit 516d, and / or the fifth slit 516e may be filled with an insulating material. For example, the third slit 516c, the fourth slit 516d, and / or the fifth slit 516e may form a first non-conductive portion, thereby insulating two adjacent conductive portions while mechanically connecting or coupling them.

[0141] According to an embodiment, the first conductive portion may be all or part of the third side surface portion 513. The third side surface portion 513 may include a first portion 513a and a second portion 513b. For example, the first portion 513a may be formed in a first length L1 along a direction parallel to a first axis (e.g., Figure 5 the folding region A). The second portion 513b may be connected to the first portion 513a and may be partially formed to be curved. The second portion 513b may be formed in a second length L2 along a direction intersecting the first axis (e.g., Figure 5 the folding region A). The first conductive portion may be all or part of the fourth side surface portion 514 and may be perpendicular to the first axis (e.g., Figure 5extends in the folding region A). According to an embodiment, the first length L1 may be substantially the same as the third length L3, and the second length L2 may be substantially the same as the fourth length L4.

[0142] According to an embodiment, the third slit 516c may be formed at a position symmetrical to the eighth slit 526c. For example, when viewed from above the first rear cover (e.g., Figure 2 the first rear cover 240) of the electronic device in the folded state, at least a part of the third slit 516c may overlap with the eighth slit 526c.

[0143] According to an embodiment, the radiation characteristics depending on the position of the third slit 516c will be described in more detail below with reference to Fig.13 or Fig.14 The above values regarding the position of the third slit 516c are example values applicable to an electronic device (e.g., Figure 4 the electronic device 200) in which the width of the first side surface member 501 (e.g., the length along the Figure 2 X-axis direction) is 200 mm or less, but it should be noted that the embodiments of the present disclosure are not limited thereto. For example, considering the resonant frequency to be formed using the radiation conductor or the size of the electronic device to be actually manufactured (e.g., Figure 2 the electronic device 200), the third slit 516c may be formed at a position different from the position of the example value.

[0144] According to an embodiment, as described above in connection with Figure 6 and Figure 7 the first length L1 of the third side surface portion 513 along a direction parallel to the first axis (e.g., Figure 5 the folding region A) may be 40 mm, and the second length L2 of the third side surface portion 513 along a direction crossing the first axis (e.g., Figure 5 the folding region A) may be 18.6 mm. For example, the length of the third side surface portion 513 formed based on the first length L1 and the second length L2 may correspond to the electrical length of a selected resonant frequency (e.g., a low-frequency band resonant frequency).

[0145] Referring to Figure 6 and Figure 7 the third side surface portion 513 may be electrically connected to the printed circuit board 530. For example, the third side surface portion 513 may include a ground terminal 513c, a power supply terminal 513d, and / or a switching terminal 513e.

[0146] The ground terminal 513c may be electrically connected to the ground portion G provided on the printed circuit board 530, and the ground terminal 513c may be provided in the third side surface portion 513 to be connected to a wireless communication circuit (e.g., Figure 1of the processor 120 or the communication module 190).

[0147] The ground terminal 513c may include a ground member, and the ground terminal 513c may be electrically connected to an antenna ground. For example, the ground member may include at least one of a leaf spring, a C-shaped clip, a screw, or a flexible printed circuit board 530 (FPCB). The antenna ground may be a conductive layer adjacent to the antenna and may be a conductive layer electrically connected to the ground terminal 513c. For example, the antenna ground may include at least one of a PCB ground, a conductive bracket, and a display ground.

[0148] As Figure 7 The power supply terminal 513d shown may be electrically connected to a power supply portion F provided on the printed circuit board 530. For example, the power supply terminal 513d may be provided in the third side surface portion 513 to be able to receive power via the power supply portion F of the printed circuit board 530 electrically connected between the ground terminal 513c and the switching terminal 513e.

[0149] According to an embodiment, an electronic device (e.g., Figure 1 the electronic device 200) may include a switching portion S disposed in a space formed by a foldable housing (e.g., Figure 2 a pair of housing structures 210 and 220). For example, among a plurality of housing structures 210 and 220 and a hinge structure (e.g., Figure 4 the hinge structure 264) that support a display (e.g., Figure 4 the display 230), the switching portion S may be electrically connected to a switching terminal 513e provided in the third side surface portion 513, and may selectively connect the antenna ground to the third side surface portion 513 via one of a plurality of matching paths M1, M2,..., Mx. The antenna ground may include the above-described ground portion. Here, "the switching portion selectively connects one of the plurality of matching paths to the third side surface portion 513" may mean that the switching portion S does not connect the third side surface portion 513 to the antenna ground (e.g., the ground portion G), or the switching portion S may connect the third side surface portion 513 to the antenna ground via a matching path M1, M2,..., Mx selected under the control of a processor (e.g., Figure 1 the processor 120). According to an embodiment, the switching portion S may selectively combine two or more matching paths under the control of the processor to connect the third side surface portion 513 to the antenna ground. According to an embodiment, by using the switching portion S to connect the third side surface portion 513 to the antenna ground via the selected matching path, the radiation characteristics of the antenna device 500 may be stabilized or the resonance frequency may be adjusted. According to an embodiment, the antenna ground (e.g., the ground portion G) may be included in the electronic device (e.g., Figure 2the ground region of the circuit board provided in the electronic device 200), the ground provided in the display (e.g., Figure 4 the display 230), or a metal structure electrically connected to the ground. According to an embodiment, the matching paths M1, M2, ..., Mx may remain connected to a common ground (e.g., the ground portion G).

[0150] According to an embodiment, the wireless communication circuit may be electrically connected to a power supply terminal 513d provided in the third side surface portion 513 and perform wireless communication using the third side surface portion 513. According to an embodiment, the third side surface portion 513 may form resonant frequencies of various frequency bands depending on its electrical length, and the wireless communication circuit may be configured to transmit or receive signals in a frequency band in the range of about 500 MHz to about 6 GHz using the third side surface portion 513. According to an embodiment, the electronic device 200 may include a plurality of wireless communication circuits, and the wireless communication circuits may transmit or receive signals of different frequency bands using the third side surface portion 513.

[0151] According to an embodiment, a power supply terminal 514a provided in the fourth side surface portion 514 may be electrically connected to a power supply portion F of a printed circuit board (e.g., Figure 7 the printed circuit board 530), and a part of the conductive material portion of the fourth side surface portion 514 may be used as an additional radiation conductor for forming another resonant frequency. For example, the electronic device 200 may use a part of the fourth side surface portion 514 to perform wireless communication. According to an embodiment, the fourth side surface portion 514 may be electrically connected to the ground portion at different positions.

[0152] According to an embodiment, the second side surface member 502 may include a sixth side surface portion 521, a seventh side surface portion 522, an eighth side surface portion 523, a ninth side surface portion 524, and / or a tenth side surface portion 525. According to an embodiment, the sixth to tenth side surface portions 521, 522, 523, 524, and 525 may also be referred to as the "sixth to tenth side surface portion (525) frame". According to an embodiment, at least a part of the sixth side surface portion 521 may be disposed in parallel with the folding region A. The seventh side surface portion 522 may be disposed at a distance from one end (e.g., the top) of the sixth side surface portion 521 in a direction intersecting or substantially perpendicular to the folding region A. The eighth side surface portion 523 may be disposed at a distance from the opposite end (e.g., the bottom) of the sixth side surface portion 521 in parallel with the folding region A.

[0153] The ninth side surface portion 524 may be disposed adjacent to one end of the eighth side surface portion 523 and may be configured to be spaced apart from the eighth side surface portion 523 and may extend into the folding region A in a crossing direction or in a substantially perpendicular direction. The tenth side surface portion 525 may extend substantially parallel to the folding region A. One end of the tenth side surface portion 525 is disposed to be spaced apart from one end of the seventh side surface portion 522, and the other end of the tenth side surface portion 525 is disposed to be spaced apart from one end of the ninth side surface portion 524. According to an embodiment, the tenth side surface portion 525 may be disposed adjacent to a hinge structure or a hinge cover (e.g., Figure 4 the hinge structure 264 or the hinge cover 265) and may extend substantially parallel to the hinge structure or the hinge cover along the folding region A.

[0154] According to an embodiment, the second side surface member 502 may include additional (multiple) slits 526a, 526b, 526c, 526d, and 526e that at least partially separate conductive material portions. A structure formed of an insulating material may be formed in at least a portion of the region surrounded by the fifth to tenth side surface portions 521, 522, 523, 524, and 525. According to an embodiment, the (multiple) slits 526a, 526b, 526c, 526d, and 526e may be filled with an insulating material. For example, the second side surface member 502 may include an insulating material portion that insulates some conductive material portions from other conductive material portions.

[0155] According to an embodiment, the sixth slit 526a may be formed between one end of the sixth side surface portion 521 and the seventh side surface portion 522, and the seventh slit 526b may be formed between the seventh side surface portion 522 and the tenth side surface portion 525. The eighth slit 526c may be formed between the opposite end of the sixth side surface portion 521 and the eighth side surface portion 523. The ninth slit 526d may be formed between the eighth side surface portion 523 and the ninth side surface portion 524, and the tenth slit 526e may be formed between the ninth side surface portion 524 and the tenth side surface portion 525.

[0156] At least a portion of the seventh side surface portion 522, the eighth side surface portion 523, and the ninth side surface portion 524 may be formed of a conductive material. At least a portion of the seventh side surface portion 522, the eighth side surface portion 523, and / or the ninth side surface portion 524 may be formed as a radiating conductor. According to an embodiment, the seventh side surface portion 522, the eighth side surface portion 523, and / or the ninth side surface portion 524 may be used as an antenna radiator (e.g., a radiating conductor) of an electronic device (e.g., Figure 2 the electronic device 200). For example, a processor of the electronic device 200 (e.g., Figure 1The processor 120 ) or a communication module (eg, the communication module 190 ) may perform wireless communication using a portion of the seventh side surface portion 522 , the eighth side surface portion 523 , and the ninth side surface portion 524 .

[0157] For example, when an electronic device (e.g. Figure 2 The electronic device 200 is in a folded state from the first rear cover (eg, Figure 2 When viewed from above the first rear cover 240 of the mobile phone, at least a portion of the eighth slit 526c may overlap with the third slit 516c.

[0158] According to an embodiment, the third length L3 may be substantially the same as the first length L1, and the fourth length L4 may be substantially the same as the second length L2. The values of the third length L3 and the fourth length L4 may be Figure 5 The first length L1 and the second length L2 are the same or similar, and a repeated description thereof will not be given below.

[0159] Figure 8 FIG. 2 is a diagram showing an electronic device (eg, Figure 2 A perspective view of an electronic device 200).

[0162] Fig.11 FIG. 2 is a diagram showing an electronic device (eg, Figure 2 2 is a bottom view of a fourth slit 516d, a fifth slit 516e, a ninth slit 526d, and a tenth slit 526e among components of an electronic device 200 of FIG.

[0163] Reference Figures 8 to 11 , electronic devices (e.g. Figure 2 The electronic device 200 may include a first housing structure (eg, Figure 2 The first shell structure 210), the second shell structure (for example, Figure 2 The second housing structure 220) and the hinge structure (eg, Figure 4 The hinge structure 264). Due to the first shell structure (eg, Figure 2The first housing structure 210) and the second housing structure (e.g., Figure 2 The second housing structure 220) of each rotates about a hinge structure (e.g., Figure 4 The hinge structure 264) of, so that they can be folded such that the first surface 211 of the first housing structure 210 faces the third surface 221 of the second housing structure 220.

[0164] According to an embodiment, when the first side surface member 501 and the second side surface member 502 are viewed from the outside, as Fig.10 shown, in the position where the first housing structure is folded to face the second housing structure, the third slit 516c and the eighth slit 526c can be aligned adjacent to each other. According to an embodiment, the third slit 516c may be formed in the first side surface member 501, and the eighth slit 526c may be formed in the second side surface member 502. In this state, when the first side surface member 501 or the second side surface member 502 is viewed from the outside in the position where the first housing structure is folded to face the second housing structure, the third slit 516c formed in the first side surface member 501 and the eighth slit 526c formed in the second side surface member 502 can be aligned adjacent to each other.

[0165] According to an embodiment, when the bottoms of the first side surface member 501 and the second side surface member 502 are viewed from the outside in the folded state of the electronic device (e.g., Figure 2 The electronic device 200) of, the fourth slit 516d and the fifth slit 516e formed in the first side surface member 501 and the ninth slit 526d and the tenth slit 526e formed in the second side surface member 502 can be aligned adjacent to each other. For example, in the folded state of the electronic device (e.g., Figure 2 The electronic device 200) of, the non-conductive portions in the fourth slit 516d and the fifth slit 516e and the ninth slit 526d and the tenth slit 526e can also be aligned adjacent to each other.

[0166] Referring to Figure 2 and Figure 5 , since the first housing structure (e.g., Figure 2 The first housing structure 210) and the second housing structure (e.g., Figure 2 The second housing structure 220) of each rotates about a hinge structure (e.g., as Figure 4 The hinge structure 264) of, so that they can be folded such that the first surface 211 of the first housing structure 210 and the third surface 221 of the second housing structure 220 can be arranged side by side. For example, in the state where the first surface 211 faces the third surface 221, the first housing structure 210 and the second housing structure 220 can rotate about a hinge structure (e.g., Figure 4rotate about the hinge structure 264), unfold, and position itself side by side. In this case, the first slit 516a, the second slit 516b, the third slit 516c, the fourth slit 516d, and the fifth slit 516e of the first side surface member 501 of the first housing structure 210 and the sixth slit 526a, the seventh slit 526b, the eighth slit 526c, the ninth slit 526d, and the tenth slit 526e of the second support member 262 of the second housing structure 220 may be arranged symmetrically with respect to the hinge structure (e.g., Figure 4 of the hinge structure 264) with respect to each other.

[0167] Fig.12 is a view showing the configuration of the antenna device 600 in an electronic device (e.g., Figure 1 the electronic device 200) according to an embodiment of the present disclosure.

[0168] Referring to Fig.12 , the first conductive portion of the antenna device 600 may be all or part of the third side surface portion 613 of the first side surface member. The third side surface portion 613 may include a first portion 613a and a second portion 613b. For example, the first portion 613a may be formed in a first length L1 along a direction parallel to the first axis (e.g., Figure 5 the folding region A). The second portion 613b may be connected to the first portion 613a and formed to be curved. The second portion 513b may be formed in a second length L2 along a direction intersecting the first axis (e.g., Figure 5 the folding region A). The first conductive portion may be all or part of the fourth side surface portion 614 and may extend perpendicular to the first axis (e.g., Figure 5 the folding region A).

[0169] According to an embodiment, the third slit 616c may be formed between the first side surface portion 611 and the third side surface portion 613 at a position at a predetermined distance from the first portion 613a of the third side surface portion 613 along a direction parallel to the first axis (e.g., Figure 5 the folding region A). According to an embodiment, since the third slit 616c is formed at a position of the first length L1 (which is a distance D1 not less than 30 mm and not greater than 50 mm (e.g., 46 mm) from the first portion 613a of the third side surface portion), it is possible to provide a plurality of housing structures 210 and 220 and a hinge structure (e.g., Figure 4 for supporting one display (e.g., Figure 4The radiation conductor (e.g., the third side surface portion 613) required for the hinge structure 264) can reduce the degradation of the radiation performance of the radiation conductor (e.g., the third side surface portion 613), and can reduce the degradation of the radiation performance of the radiation conductor (e.g., the third side surface portion 613) caused by the influence of the user's body when the user's hand is held on the electronic device (e.g., Figure 1 of the electronic device 101). In this way, the third slit 616c can enhance the radiation performance of the radiation conductor (e.g., the third side surface portion). For example, when the human body approaches the end of the radiation conductor (e.g., the third side surface portion 613), the resonance frequency may change drastically, resulting in degradation of the radiation performance. Therefore, repositioning the third slit 616c by the first length L1 can enhance the radiation performance of the radiation conductor (e.g., the third side surface portion).

[0170] According to an embodiment, as described above in connection with Fig.12 the first length L1 of the third side surface portion 613 may be a length (e.g., 46 mm) between 0 mm and 50 mm along a direction parallel to the first axis (e.g., Figure 5 the folding region A), and the second length L2 of the third side surface portion 613 may be a length between 2.6 mm and 22.6 mm (e.g., 12.6 mm) along a direction intersecting the first axis (e.g., Figure 5 the folding region A).

[0171] For example, the sum of the first length L1 and the second length L2 may correspond to the electrical length of the low-frequency band resonance frequency, and allowing the first length L1 to be greater than the second length L2 can Fig.13 turn the flow of the ground current shown from the horizontal direction to the vertical direction, as described below. This can minimize the degradation of the radiation performance of the radiation conductor (e.g., the third side surface portion 513) and thus enhance the radiation performance of the radiation conductor (e.g., the third side surface portion 513).

[0172] Referring to Fig.12 the third side surface portion 613 can be electrically connected to a printed circuit board (e.g., Figure 7 the printed circuit board 530). For example, the third side surface portion 613 may include a ground terminal 613c and a power supply terminal 613d.

[0173] The ground terminal 613c can be electrically connected to a ground portion G provided on the printed circuit board, and the ground terminal 613c can be provided in the third side surface portion 613 to be connected to a wireless communication circuit (e.g., Figure 1 the processor 120 or the communication module 190) at a position between the fourth slit 616d and the power supply terminal 613d.

[0174] The ground terminal 613c may include a ground member, and the ground terminal 613c may be electrically connected to the antenna ground.

[0175] The power supply terminal 613d may be electrically connected to a power supply portion F provided on a printed circuit board (e.g., Figure 7 the printed circuit board 530). For example, the power supply terminal 613d may be provided in the third side surface portion 613 so as to be able to receive power via the power supply portion F electrically connected at a position adjacent to the ground terminal 613c on the printed circuit board (e.g., Figure 7 the printed circuit board 530).

[0176] According to an embodiment, independent of the third side surface portion 613, a power supply terminal 614a provided in the fourth side surface portion 614 may be electrically connected to the power supply portion F of a printed circuit board (e.g., Figure 7 the printed circuit board 530), and a part of the conductive material portion of the fourth side surface portion 614 may be used as an additional radiation conductor for forming another resonance frequency. For example, the power supply terminal 614a may be provided in the fourth side surface portion 614 so as to be able to receive power via the power supply portion F electrically connected at a position adjacent to the fourth slit 616d on the printed circuit board (e.g., Figure 7 the printed circuit board 530).

[0177] For example, with reference to Fig.13 and Fig.15 there is described, in a foldable electronic device (e.g., Figure 2 the electronic device 200), a plurality of housings (e.g., Figure 4 the first housing structure 210 and the second housing structure 220) and a hinge structure (e.g., Figure 2 the hinge structure 264) for supporting a display (e.g., Figure 4 the display 230), changes in radiation characteristics and current flow depending on the position of slits (e.g., Figure 2 the third slit 516c and the eighth slit 526c) when conductive material portions of the first housing structure and the second housing structure (e.g., Figure 5 the first housing structure 210 and the second housing structure 220) are used as radiation conductors.

[0178] Fig.13 FIG. Figure 2 is a view showing current flow in the first side surface member 501 and the second side surface member 502 of the first housing structure and the second housing structure (e.g., Figure 2 the first housing structure 210 and the second housing structure 220) formed in an electronic device (e.g.,

[0179] Fig.13 the electronic device 200) according to an embodiment of the present disclosure.shows the current flow in the case of implementing a radiation conductor by positioning the third slit 516c between the first side surface portion 511 and the third side surface portion 513 and positioning the eighth slit (e.g., Figure 5 the eighth slit 526c) of Figure 5 between the sixth side surface portion (e.g., Figure 5 the sixth side surface portion 521) and the eighth side surface portion (e.g., Figure 6 the eighth side surface portion 523) of

[0180] The power supply portion and the ground portion are coupled in the same manner as shown in Figure 6 and Fig. 9 It can be found that when using the third side surface portion 513 and the eighth side surface portion 523 as radiation conductors to perform wireless communication, the current flow in the electronic device 200 can be redirected from the short axis direction (e.g., the X-axis direction) of the electronic device to the long axis direction (e.g., the Y-axis direction).

[0181] Fig.14 is a view showing the flow of radiation current through the ground of a display (e.g., Figure 4 the display 230) when the conductive layer (e.g., a shielding sheet or a display ground layer) of the display functions as an antenna ground when the electronic device is in a folded state according to an embodiment of the present disclosure. Figure 4 the display 230) of

[0182] Referring to Fig.13 and Fig.14 , in the folded state of an electronic device (e.g., Figure 2 the electronic device 200), the conductive layer of the display (e.g., Figure 4 the display 230) is included as an antenna ground, and radiation current of a specific frequency band (e.g., 1 GHz) flows through the conductive layer of the display (e.g., Figure 4 the display 230). The ground of the display (e.g., Figure 4 the display 230) can have the maximum electrical length among the antenna grounds and thus can have the greatest impact on radiation. For example, in the case where the ground of the display (e.g., Figure 4 the display 230) is formed longer along the X-axis, if the electronic device (e.g., Figure 2 the electronic device 200) is folded, the X-axis can be formed as the main radiation current direction of the antenna. In the folded electronic device (e.g., Figure 2In the electronic device 200, the flow of radiated current in the first side surface member 501 and the second side surface member 502 may be disturbed due to their mutual interference, resulting in performance degradation. This can be solved by forming the third slit 516c and the eighth slit 526c, and the third side surface portion 513 and the eighth side surface portion 523 (e.g., radiating conductors) in the first side surface member 501 and the second side surface member 502. For example, allowing the first length L1 of the third side surface portion 513 and the third length L3 of the eighth side surface portion 523 to be greater than the second length L2 of the third side surface portion 513 and the fourth length L4 of the eighth side surface portion 523 enables the current induced in adjacent grounds to be induced along the Y-axis rather than the X-axis, thereby minimizing interference.

[0183] Fig.15 is a graph showing the radiation pattern of the electronic device 200 in the low frequency band (e.g., 800 MHz band) in the folded state according to an embodiment of the present disclosure.

[0184] Referring to Fig.15 ,"K1" represents the radiation pattern of the antenna obtained by supplying power to the radiating conductor (e.g., Figure 5 the fourth side surface portion 514) provided at the bottom of the electronic device in the low frequency band (e.g., 800 MHz band) when the electronic device has no side slits (e.g., Figure 5 the third slit 516c and the eighth slit 526c) but has bottom slits (e.g., Figure 5 the fourth slit 516d, the fifth slit 516e, the ninth slit 526d, and the tenth slit 526e), and "K2" represents the radiation pattern of the antenna obtained by supplying power to the third side surface portion and the eighth side surface portion (e.g., Figure 5 the third side surface portion 513 and the eighth side surface portion 523) used as radiating conductors in the low frequency band (e.g., 800 MHz band) when the electronic device has side slits (e.g., Figure 5 the third slit 516c and the eighth slit 526c) and the third side surface portion and the eighth side surface portion (e.g., Figure 5 the third side surface portion 513 and the eighth side surface portion 523).

[0185] For example, in the plurality of housing structures 210 and 220 that support a display (e.g., Figure 4 the display 230) and the hinge structure (e.g., Figure 4 the hinge structure 264), compared with the radiating conductor provided at the bottom of the electronic device (e.g., Figure 5 the fourth side surface portion 514), after forming the side slits, the third side surface portion and the eighth side surface portion (e.g., Figure 5The radiation conductors on the third side surface portion 513 and the eighth side surface portion 523) can generate radiation patterns in more directions when used as an antenna.

[0186] As described above in connection with Fig.10 and Fig.11 When observing the sides of the first side surface member 501 and the second side surface member 502 from the outside in the folded state of the electronic device (e.g., Figure 2 the electronic device 200), the third slit 516c and the eighth slit 526c can be aligned adjacent to each other, and when observing the bottoms of the first side surface member 501 and the second side surface member 502 from the outside in the folded state of the electronic device (e.g., Figure 2 the electronic device 200), the fourth slit 516d, the fifth slit 516e, the ninth slit 526d, and the tenth slit 526e can be aligned adjacent to each other.

[0187] As Fig.15 shown, it can be determined that "K2" generates a more stable radiation pattern than "K1". For example, the radiation pattern of "K2" is a stable radiation pattern, close to circular, while the radiation pattern of "K1" is an irregular radiation pattern far from circular. Therefore, when the electronic device is in the folded state, forming the third slit (e.g., Figure 5 the third slit 516c) and the eighth slit (e.g., Figure 5 the eighth slit 526c) in the sides of the first side surface member 501 and the second side surface member 502 allows for stable antenna performance in the multiple housing structures 210 and 220 that support a display (e.g., Figure 4 the display 230) and the hinge structure (e.g., Figure 4 the hinge structure 264), thereby improving the antenna performance and thus reducing the degradation of the radiation performance of the radiation conductor due to the influence of the user's body when the user makes a call with the electronic device 200 in his hand.

[0188] Fig.16A is a view showing the first distance G1, the second distance G2, the third distance G3, and the fourth distance G4 of the slot (e.g., Figure 2 the third slit 516c) formed in the first side surface (e.g., Figure 5 the first side surface 213a) of the electronic device 200, or the first distance H1, the second distance H2, the third distance H3, and the fourth distance H4 of the slot (e.g., Figure 5 the fourth slit 516d) formed in the third side surface (e.g., the third side surface 213c) of the electronic device 200, in the case where the folded electronic device 200 is in the user's hand (e.g., the right hand).

[0189] Fig. 16B This shows the fourth distance G4 of a slot (e.g., the third slot 516c of Figure 2 the first side surface 213a) formed in the first side surface of the electronic device 200 when the folded electronic device 200 is in a user's hand (e.g., the left hand), or the first distance H1 of a slot (e.g., Figure 5 the fourth slot 516d) formed in the third side surface of the electronic device (e.g., the third side surface 213c). Figure 5 View of the first distance H1.

[0190] Fig.17 This shows the variation of the radiation characteristics depending on the first distance G1, second distance G2, third distance G3, and fourth distance G4 of slots (e.g., Figure 2 the third slot 516c) formed in the first side surface member (e.g., Figure 5 the first side surface member 501) of the electronic device according to an embodiment of the present disclosure.

[0191] Referring to Fig.16A , the slot 516c formed in the first side surface of the electronic device 200 can be formed at positions of the first distance G1, second distance G2, third distance G3, and fourth distance G4. For example, the first distance G1, second distance G2, third distance G3, and fourth distance G4 can be 10 mm, 20 mm, 30 mm, and 40 mm respectively. The slot 516d formed in the third side surface of the electronic device can be formed at positions of the first distance H1, second distance H2, third distance H3, and fourth distance H4. For example, the first distance H1, second distance H2, third distance H3, and fourth distance H4 can be 18.5 mm, 28.5 mm, 38.5 mm, and 48.5 mm respectively.

[0192] Referring to Fig. 16B , the fourth distance G4 of the slot 516c formed in the first side surface of the electronic device 200 can be 40 mm. The first distance H1 of the slot 516d formed in the third side surface of the electronic device 200 can be 18.5 mm.

[0193] Referring to Fig.17 , it can be seen that, compared with the first distance G1, second distance G2, and third distance G3, the fourth distance G4 of the slot 516c formed in the first side surface of the electronic device 200 can ensure better radiation efficiency.

[0205] According to an embodiment, a plurality of first connection members 1005 may be disposed in at least a portion of the first housing structure 210 to electrically connect at least one first radiation conductor 1001 and at least one second radiation conductor 1002 to the switching unit 1300. A plurality of second connection members 1006 may be disposed in at least a portion of the first and second housing structures 210 and 220 and at least a portion of the hinge structure 264 to electrically connect at least one third radiation conductor 1003 and at least one fourth radiation conductor 1004 to the switching unit 1300. For example, the switching unit 1300 may be disposed in the first housing structure 210. As another example, the switching unit 1300 may be disposed in the communication module 1200 described below. For example, the switching unit 1300 may be disposed inside or outside the communication module 1200. In this state, a plurality of second connection members 1006 may electrically connect at least one third radiation conductor 1003 and at least one fourth radiation conductor 1004 to the switching unit 1300, which is disposed in the second housing structure 220. In this case, the plurality of second connection members 1006 may be electrically connected to the switching unit 1300 via the hinge structure 264.

[0206] At least a portion of at least one of the first to fourth radiation conductors 1001, 1002, 1003, and 1004 may be formed of a conductive material. For example, at least one of the first to fourth radiation conductors 1001, 1002, 1003, and 1004 may be used as an antenna radiator (e.g., a radiation conductor) of an electronic device (e.g., Figure 2 the electronic device 200). For example, in the plurality of housing structures 210 and 220 that support a display (e.g., Figure 4 the display 230) and a hinge structure (e.g., Figure 4 the hinge structure 264), the processor 1400 or the communication module 1200 of the electronic device 200 (e.g., Figure 1 the processor 120 or the communication module 190) may use a portion of at least one of the first to fourth radiation conductors 1001, 1002, 1003, and 1004 to transmit / receive radio signals. The communication module 1200 may perform wireless communication between the electronic device 200 and an external electronic device (e.g., Figure 1 the external electronic device 102 or 104).

[0207] At least one first radiation conductor 1001 and at least one third radiation conductor 1003 may be formed of a main antenna, and at least one second radiation conductor and at least one fourth radiation conductor 1004 may be formed of a sub-antenna.

[0208] For example, the main antenna may include at least one of an LTE communication antenna or 3G, 4G, and 5G communication antennas. The sub-antenna may include at least one of a Wi-Fi antenna for wireless LAN communication, a Bluetooth antenna or a ZigBee antenna for short-range wireless communication, a wireless charging antenna for wirelessly charging a battery, a broadcast communication antenna, and a Global Positioning System (GPS) antenna.

[0209] According to an embodiment, the plurality of first connection members 1005 and the plurality of second connection members 1006 may include at least one of a coaxial cable, a flexible printed circuit board (FPCB), a microstrip line, or a strip line. According to an embodiment, although the plurality of first connection members 1005 and the plurality of second connection members 1006 are exemplified as including a coaxial cable, an FPCB, a microstrip line, or a strip line, embodiments of the present disclosure are not limited thereto. For example, as the plurality of first connection members 1005 and the plurality of second connection members 1006, any other various components that can electrically connect at least one of the first to fourth radiation conductors 1001, 1002, 1003, and 1004 to the switching unit 1300 may be used.

[0210] According to an embodiment, as described above in connection with Fig.18 Since the plurality of first connection members 1005 and the plurality of second connection members 1006 are formed of a coaxial cable, the radiation characteristics of the antenna can be enhanced in the plurality of housing structures 210 and 220 that support one display (e.g., Figure 4 display 230) and the hinge structure (e.g., Figure 4 hinge structure 264). This can enhance the function of at least one of the first to fourth radiation conductors 1001, 1002, 1003, and 1004 as a radiator.

[0211] According to an embodiment, since the plurality of first connection members 2005 and the plurality of second connection members 2006 are formed of an FPCB as described above in connection with Fig.19 it is possible to prevent the plurality of first connection members 2005 and the plurality of second connection members 2006 from being damaged due to repeated folding or unfolding of the first housing structure and the second housing structure (e.g., Figure 2 first housing structure 210 and second housing structure 220). For example, at least a part of the plurality of second connection members 2006 formed of an FPCB may be disposed in the folding part of the hinge structure 264, and in this state, it is possible to prevent the plurality of second connection members 1006 from being damaged in the folding part of the hinge structure 264 when the first housing structure and the second housing structure (e.g., Figure 2 first housing structure 210 and second housing structure 220) are repeatedly folded or unfolded. Therefore, the electrical connection between at least one of the third radiation conductor 1003 and at least one of the fourth radiation conductor 1004 and the switching unit 1300 can be enhanced.

[0212] Fig. 20 is a view showing a configuration of a first side surface member 1501 and a second side surface member 1502 electrically connected to a switching unit 1300 in a first housing structure of an electronic device (e.g., Figure 2 electronic device 200) using a coaxial cable and a flexible printed circuit board.

[0213] The electronic device 200 may be the same as or similar to the above-described electronic device (e.g., Figure 2 electronic device 200) at least in part of its configuration. Accordingly, at least one of the components of the electronic device 200 may be the same as or similar to Figure 2 at least one of the components of the electronic device 200, and thus will not be described repeatedly below.

[0214] Referring to Fig. 20 , a plurality of third connection members 1007 may be provided in a first housing structure (e.g., Figure 2 first housing structure 210) that electrically connect at least one first radiation conductor 1001 and at least one second radiation conductor 1002 to the switching unit 1300, and a plurality of fourth connection members 1008 may be provided in a second housing structure (e.g., Figure 2 second housing structure 220) that electrically connect at least one third radiation conductor 1003 and at least one fourth radiation conductor 1004 to the switching unit 1300. A plurality of fifth connection members 1009 that electrically connect the plurality of fourth connection members 1008 and the switching unit 1300 may be provided in at least part of the first and second housing structures 210 and 220 and at least part of the hinge structure 264. For example, the plurality of third connection members 1007 may be provided in the first housing structure 210, and in this state, the plurality of fourth connection members 1008 may be provided in the second housing structure 220, and the plurality of fifth connection members 1009 may be provided in at least part of the hinge structure 264.

[0215] According to an embodiment, first to fifth connection ends 1007a, 1007b, 1007c, 1007d, and 1007e may be formed at corresponding first ends of the plurality of third connection members 1007 to be electrically connected to a ground end (not shown) formed in first to fifth side surface portions 1511, 1512, 1513, 1514, and 1515, and first to fifth switching connection ends 1007a-1, 1007b-1, 1007c-1, 1007d-1, and 1007e-1 may be formed at corresponding second ends of the plurality of third connection members 1007 to be electrically connected to a switching end formed in the switching unit 1300.

[0216] The sixth to tenth connection terminals 1008a, 1008b, 1008c, 1008d, and 1008e may be formed at corresponding first ends of a plurality of fourth connection members 1008 to be electrically connected to ground terminals formed in the sixth to tenth side surface portions 1521, 1522, 1523, 1524, and 1525, and the eleventh to fifteenth connection terminals 1008a-1, 1008b-1, 1008c-1, 1008d-1, and 1008e-1 may be formed at corresponding second ends of a plurality of fourth connection members 1008 to be electrically connected to the sixteenth to twentieth connection terminals 1009a, 1009b, 1009c, 1009d, and 1009e described below.

[0217] The sixteenth to twentieth connection terminals 1009a, 1009b, 1009c, 1009d, and 1009e may be formed at corresponding first ends of a plurality of fifth connection members 1009 to be electrically connected to the eleventh to fifteenth connection terminals 1008a-1, 1008b-1, 1008c-1, 1008d-1, and 1008e-1 of a plurality of fourth connection members 1008, and the twenty-first to twenty-fifth switching connection terminals 1009a-1, 1009b-1, 1009c-1, 1009d-1, and 1009e-1 may be formed at corresponding second ends of a plurality of fifth connection members 1009 to be electrically connected to switching terminals formed in the switching unit 1300.

[0218] According to an embodiment, a plurality of third connection members 1007 and a plurality of fourth connection members 1008 may be formed of coaxial cables, and a plurality of fifth connection members may be formed of flexible printed circuit boards (FPCBs).

[0219] For example, placing a plurality of third connection members 1007 and a plurality of fourth connection members 1008 formed of coaxial cables in the first housing structure 210 and the second housing structure 220 may enhance the electrical connection between at least one first radiation conductor 1001 and at least one second radiation conductor 1002 and the switching unit 1300, and enhance the radiation characteristics of the antenna.

[0220] A plurality of fifth connection members 1009 formed of FPCBs may be disposed in a folded portion of the hinge structure 264. Thus, even if the first housing structure 210 and the second housing structure 220 are repeatedly folded or unfolded, damage to the plurality of fifth connection members 1009 can be prevented. By preventing damage to the plurality of fifth connection members 1009 formed of FPCBs, the electrical connection between at least one third radiation conductor 1003 and at least one fourth radiation conductor 1004 and the switching unit 1300 can be enhanced.

[0221] In this way, a plurality of third connection members 1007 formed of coaxial cables and a plurality of fourth connection members 1008 are provided in the first housing structure 210 and the second housing structure 220, and a plurality of fifth connection members 1009 formed of FPCB are provided in the folding portion of the hinge structure 264. In the plurality of housing structures 210 and 220 that support a display (e.g., Figure 4 the display 230) and the hinge structure (e.g., Figure 4 the hinge structure 264), the electrical connection between at least one of the first to fourth radiation conductors 1001, 1002, 1003, and 1004 and the switching unit 1300 can be enhanced, and thus the function of at least one of the first to fourth radiation conductors 1001, 1002, 1003, and 1004 as an antenna can be enhanced while ensuring stable antenna performance. In addition, a plurality of fifth connection members 1009 formed of FPCB can be provided in the folding portion of the hinge structure 264, and in this state, the fifth connection members 1009 can be prevented from being damaged in the folding portion of the hinge structure 264 when the first housing structure 210 and the second housing structure 220 are repeatedly folded or unfolded. Therefore, a plurality of fifth connection members 1009 formed of FPCB can enhance the electrical connection between the switching unit 1300 and at least one of the first to fourth radiation conductors 1001, 1002, 1003, and 1004 and maintain a stable electrical connection between the switching unit 1300 and at least one of the first to fourth radiation conductors 1001, 1002, 1003, and 1004.

[0222] Fig.21 is a view showing a held state of a second housing structure (e.g., Figure 2 the second housing structure 220) among the components of an electronic device (e.g., Figure 2 the electronic device 200) according to an embodiment of the present disclosure.

[0223] Fig. 22 is a view showing a held state of a first housing structure (e.g., Figure 2 the first housing structure 210) among the components of an electronic device (e.g., Figure 2 the electronic device 200) according to an embodiment of the present disclosure.

[0224] Fig.23 is a view showing a held state of a first housing structure and a second housing structure (e.g., Figure 2 the first housing structure 210 and the second housing structure 220) among the components of an electronic device 200 according to an embodiment of the present disclosure.

[0225] Referring to Figure 21 to Figure 23 , the electronic device 200 may include a first housing structure 210, a second housing structure 220, and a hinge structure (e.g., Figure 4 hinge structure 264). The first housing structure 210 and the second housing structure 220 can rotate about the hinge structure (e.g., Figure 4 hinge structure 264) and operate in an unfolded state or a folded state among the multiple housing structures 210 and 220 that support a display (e.g., Figure 4 display 230) and the hinge structure (e.g., Figure 4 hinge structure 264).

[0226] At least one of the components of the electronic device 200 can be the same as or similar to at least one of the components of Figures 18 to 20 antenna element 1500, and will not be described repeatedly below.

[0227] In addition, as described above in connection with Figures 18 to 20 the electronic device 200 may include at least one of the first to fourth radiation conductors 1001, 1002, 1003, and 1004, a sensor unit 1100, a communication module 1200, a switching unit 1300, a processor 1400, and a memory 1401.

[0228] The sensor unit 1100 can detect the operating state of the electronic device 200 and convert the detected information into an electrical signal. For example, the sensor unit 1100 may include at least one of a grip sensor and a proximity sensor. The proximity sensor can detect whether an external object is approaching the electronic device 200, e.g., an external object (e.g., a user's finger or a stylus) approaching on the display (e.g., Figure 4 display 230) of the electronic device 200.

[0229] The grip sensor can detect that the electronic device 200 is grasped or held in an external object (e.g., a user's hand). The grip sensor can be disposed in at least one of the left surface / right surface, top surface / bottom surface, or rear surface of the first housing structure 210 and the second housing structure 220 of the electronic device 200. The grip sensor can transmit the obtained sensor information to the processor 1400.

[0230] According to an embodiment, if a user's body touches the electronic device 200, the grip sensor can detect a capacitance change of the electronic device 200, thereby sensing the user's body touch. Thus, the grip sensor as an independent sensor for detecting a user's body touch can be installed in the electronic device 200, or the grip sensor as a non-independent sensor can be implemented to detect a capacitance change of the first housing structure 210 and the second housing structure 220 (e.g., a metal housing) of the electronic device 200.

[0231] According to an embodiment, such a grip sensor is described as an example.

[0232] For example, in the plurality of housing structures 210 and 220 and the hinge structure 264 that support a display (e.g., Figure 4 display 230), the communication module 1200 may be electrically connected to at least one of the first to fourth radiation conductors 1001, 1002, 1003, and 1004 to transmit / receive radio signals.

[0233] The switching unit 1300 may electrically connect the communication module 1200 to at least one of the first to fourth radiation conductors 1001, 1002, 1003, and 1004.

[0234] The processor 1400 may detect a hand grip on the first housing structure 210 and / or the second housing structure 220 via the sensor unit 1100 in the unfolded or folded state of the first housing structure 210 and the second housing structure 220, and control the switching unit 1300 to switch from at least one of the first radiation conductor 1001 or the second radiation conductor 1002 to at least one of the third radiation conductor 1003 or the fourth radiation conductor 1004, or from at least one of the third radiation conductor 1003 or the fourth radiation conductor 1004 to at least one of the first radiation conductor 1001 or the second radiation conductor 1002.

[0235] The memory 1401 may store a switching control program for controlling the switching unit 1300. For example, the switching control program may store data for controlling the switching unit 1300 to switch at least one of the first to fourth radiation conductors 1001, 1002, 1003, and 1004. For example, the switching control program may store data for adjustment to switch from at least one of the first radiation conductor 1001 or the second radiation conductor 1002 to at least one of the third radiation conductor 1003 or the fourth radiation conductor 1004 or from at least one of the third radiation conductor 1003 or the fourth radiation conductor 1004 to at least one of the first radiation conductor 1001 or the second radiation conductor 1002 depending on the grip on the first housing structure 210 and the second housing structure 220.

[0236] When the first housing structure 210 is held by hand in the unfolded state of the first housing structure 210 and the second housing structure 220, the processor 1400 may detect the hand-holding via the sensor unit 1100 and control the switching unit 1300 to switch from at least one of the first radiation conductors 1001 or the second radiation conductors 1002 of the first housing structure 210 to at least one of the third radiation conductors 1003 or the fourth radiation conductors 1004 of the second housing structure 220. In this case, due to the user's hand-holding, at least one of the first radiation conductors 1001 or the second radiation conductors 1002 of the first housing structure 210 may experience a reduction in radiation performance. However, since at least one of the third radiation conductors 1003 or the fourth radiation conductors 1004 of the second housing structure 220 is not in the user's hand-holding, a reduction in radiation performance caused by the influence of the human body can be prevented. Accordingly, the electronic device 200 may select at least one of the third radiation conductors 1003 or the fourth radiation conductors 1004 through the switching unit 1300 and use it as an antenna.

[0237] According to an embodiment, when the second housing structure 220 is held by hand in the unfolded state of the first housing structure (e.g., Figure 2 the first housing structure 210) and the second housing structure (e.g., Figure 2 the second housing structure 220), the processor 1400 may detect the hand-holding via the sensor unit 1100 and control the switching unit 1300 to switch from at least one of the third radiation conductors 1003 or the fourth radiation conductors 1004 of the second housing structure 220 to at least one of the first radiation conductors 1001 or the second radiation conductors 1002 of the first housing structure 210, as described above in connection with Figures 18 to 20 and Fig. 22 described. At least one of the third radiation conductors 1003 or the fourth radiation conductors 1004 of the second housing structure 220 may similarly experience a reduction in radiation performance due to the user's hand-holding. However, since at least one of the first radiation conductors 1001 or the second radiation conductors 1002 of the first housing structure 210 is not in the user's hand-holding, a reduction in radiation performance caused by the influence of the human body can be prevented. Accordingly, the electronic device 200 may select at least one of the first radiation conductors 1001 or the second radiation conductors 1002 through the switching unit 1300 and use it as an antenna, thereby ensuring stable operation of the antenna.

[0238] According to an embodiment, when both the first housing structure 210 and the second housing structure 220 are in the first housing structure (e.g., Figure 2 the first housing structure 210) and the second housing structure (e.g., Figure 2When the second housing structure 220 is held by hand in the unfolded state, the processor 1400 can detect the handhold via the sensor unit 1100 and control the switching unit 1300 to switch to at least one of the first radiation conductors 1001 or the second radiation conductors 1002 of the first housing structure 210, as described above in connection with Figures 18 to 20 and Fig.23 described. For example, at least one of the first radiation conductors 1001 or the second radiation conductors 1002 can be electrically connected to the switching unit 1300 via a plurality of first connection members 1005, and at least one of the third radiation conductors 1003 or the fourth radiation conductors 1004 can be electrically connected to the switching unit 1300 via a plurality of second connection members 1006. The lengths F1 or F2 of the plurality of first connection members 1005 can be less than the lengths F3 or F4 of the plurality of second connection members 1006.

[0239] For example, since the lengths F1 or F2 of the plurality of first connection members 1005 are less than the lengths F3 or F4 of the plurality of second connection members 1006, among the plurality of housing structures 210 and 220 and the hinge structure 264 that support a display (e.g., Figure 4 the display 230), the plurality of first connection members 1005 can result in less antenna radiation loss than the plurality of second connection members 1006. Accordingly, at least one of the first radiation conductors 1001 or the second radiation conductors 1002 can exhibit more stable radiation performance than at least one of the third or fourth radiation conductors. Accordingly, the processor 1400 can control the switching unit 1300 to select at least one of the first radiation conductors 1001 or the second radiation conductors 1002 of the first housing structure 210. Accordingly, in a case where both the first housing structure 210 and the second housing structure 220 are held by hand, at least one of the first radiation conductors 1001 or the second radiation conductors 1002 can be used as an antenna. Accordingly, the electronic device 200 can use at least one of the first radiation conductors 1001 or the second radiation conductors 1002 as an antenna to ensure stable antenna performance.

[0240] According to an embodiment, when the first housing structure 210 and the second housing structure 220 are held by hand in the unfolded state of the first housing structure (e.g., Figure 2 the first housing structure 210) and the second housing structure (e.g., Figure 2 the second housing structure 220), the processor 1400 can detect the handhold via the sensor unit 1100 and control the switching unit 1300 to switch to at least one of the first radiation conductors 1001 or the second radiation conductors 1002 of the first housing structure, as described above in connection with Fig. 16B and Figures 18 to 20As described above. For example, at least one first radiation conductor 1001 or second radiation conductor 1002 may be electrically connected to the switching unit 1300 via a plurality of first connection members 1005, and at least one third radiation conductor 1003 or fourth radiation conductor 1004 may be electrically connected to the switching unit 1300 via a plurality of second connection members 1006. Since the lengths F1 or F2 of the plurality of first connection members 1005 are less than the lengths F3 or F4 of the plurality of second connection members 1006, the plurality of first connection members 1005 may cause less antenna radiation loss than the plurality of second connection members 1006. Therefore, at least one first radiation conductor 1001 or second radiation conductor 1002 may exhibit more stable radiation performance than at least one third or fourth radiation conductor. Accordingly, the processor 1400 may control the switching unit 1300 to select at least one first radiation conductor 1001 or second radiation conductor 1002 of the first housing structure 210. Accordingly, at least one first radiation conductor 1001 or second radiation conductor 1002 may be used as an antenna while the folded first housing structure 210 and second housing structure 220 are held by a hand.

[0241] Thus, although in the plurality of housing structures 210 and 220 and the hinge structure 264 that support one display (e.g., Figure 4 the display 230), when the first housing structure 210 and the second housing structure 220 are in the unfolded state, both the first housing structure 210 and the second housing structure 220 are held by a hand, the electronic device 200 may use at least one first radiation conductor 1001 or second radiation conductor 1002 as an antenna to ensure stable antenna performance.

a second housing structure (e.g., Figure 2 the second housing structure 220), including a third surface facing a third direction, a fourth surface facing a fourth direction opposite to the third direction, and a second side surface member (e.g., Figure 5 the second side surface member 502) at least partially surrounding a space between the third surface and the fourth surface, the second housing structure (e.g., Figure 2 The second housing structure 220) is at least partially formed of a conductive material; a hinge structure (e.g., Figure 4 the hinge structure 264), rotatably connecting the first housing structure (e.g., Figure 2 the first housing structure 210) and the second housing structure (e.g., Figure 2 the second housing structure 220) and providing a folding axis (e.g., Figure 5 A), about which the first housing structure (e.g., Figure 2 the first housing structure 210) and the second housing structure (e.g., Figure 2 the second housing structure 220) rotate; and at least one printed circuit board disposed between the first and second surfaces or between the third and fourth surfaces, wherein the first side surface member (e.g., Figure 5 the first side surface member 501) and the second side surface member (e.g., Figure 5 the second side surface member 502) include: a first side surface portion disposed parallel to the folding axis (e.g., Figure 5 the first side surface portion 511); a second side surface portion (e.g., Figure 5 the second side surface portion 512), extending from one end of the first side surface portion (e.g., Figure 5 the first side surface portion 511) in a direction intersecting the folding axis (e.g., Figure 5 the first side surface portion 511); a third side surface portion (e.g., Figure 5 the third side surface portion 513), extending parallel to the folding axis (e.g., Figure 5 A) from the other end of the first side surface portion (e.g., Figure 5 the first side surface portion 511); a fourth side surface portion (e.g., Figure 5 the fourth side surface portion 514), connected to the third side surface portion (e.g., Figure 5 the third side surface portion 513) and extending from the third side surface portion (e.g., Figure 5 A) in a direction intersecting the folding axis;
