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

[0056] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology).

[0059] At least some of the above components can be interconnected and exchange signals (e.g., commands or data) with each other via a communication method between peripheral devices (e.g., a bus, GPIO (general purpose input and output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface)).

[0060] According to one embodiment, commands or data may be transmitted or received between the electronic device (101) and an external electronic device (104) via a server (108) connected to a second network (199). Each of the external electronic devices (102 or 104) may be the same or a different type of device as the electronic device (101). According to one embodiment, all or part of the operations executed in the electronic device (101) may be executed in one or more of the external electronic devices (102, 104, or 108). For example, when the electronic device (101) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (101) may, instead of or in addition to executing the function or service itself, request one or more external electronic devices to perform the function or at least part of the service.

The electronic device (101) may process the result as is or additionally and provide it as at least a portion of a response to the request. For this purpose, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example.

The RF transceiver (230) may include a mixer and an oscillator for down-conversion. The RF transceiver (230) can convert an RF signal received from the first antenna (210) and / or the second antenna (220) into a baseband signal so that it can be processed by the processor (120).

[0067] According to one embodiment, the RFFE (240) may include a first RFFE (241) for the first antenna (210) and / or a second RFFE (242) for the second antenna (220). For example, the first RFFE (241) and the second RFFE (242) may include a plurality of components electrically connected between the RF transceiver (230) and the antennas (e.g., the first antenna (210) and the second antenna (220)). For example, the first RFFE (241) and the second RFFE (242) may include components such as, but not limited to, a coupler, a power amplifier (PA), a low noise amplifier (LNA), a switch circuit, and / or a duplexer.

[0068] According to one embodiment, the first antenna (210) and the second antenna (220) may be used to transmit and / or receive signals on a designated frequency band. The first antenna (210) and the second antenna (220) may be used to transmit and / or receive signals on different frequency bands. For example, the first antenna (210) may be used to transmit and / or receive a first signal on a first frequency band. The second antenna (220) may be used to transmit and / or receive a second signal on a second frequency band, which is different from the first frequency band. However, the present invention is not limited thereto. For example, the electronic device (101) may include one or more additional antennas in addition to the first antenna (210) and the second antenna (220) illustrated in FIG. 2.

[0069] FIG. 3A illustrates a process of changing a foldable electronic device from an unfolded state to a folded state according to one embodiment. FIG. 3B illustrates a foldable housing of the foldable electronic device of FIG. 3A with the display omitted. FIGS. 3C and 3D illustrate conductive and non-conductive portions of the foldable electronic device according to various embodiments.

[0070] A foldable electronic device (300) (e.g., the electronic device (101) of FIG. 1) may include a plurality of housing parts that are rotatably coupled. Referring to FIG. 3A, the foldable electronic device (300) may include a foldable housing (301). For example, the foldable housing (301) may include a first housing part (310), a second housing part (320), and a third housing part (330) that are rotatably coupled to each other. In the present disclosure, the foldable housing (301) is described as having a structure including the first housing part (310), the second housing part (320), and the third housing part (330), but is not limited thereto. For example, the foldable housing (301) may include four or more housing parts or two housing parts.

[0071] For example, the foldable electronic device (300) may include hinge assemblies (e.g., a first hinge assembly (341) and a second hinge assembly (342)) for a deformable structure of the foldable housing (301). For example, the hinge assemblies may rotatably couple the first housing part (310), the second housing part (320), and the third housing part (330) to each other. For example, depending on the structure in which the housing (301) is folded, the connection relationship between the hinge assembly and the housing parts may be different.

[0072] Referring to FIG. 3A, the second housing part (320) may be rotatably coupled to one side of the first housing part (310). The third housing part (330) may be rotatably coupled to the other side of the first housing part (310), which is opposite to the one side of the first housing part (310). For example, the hinge assembly may include a first hinge assembly (341) that rotatably couples the second housing part (320) to one side of the first housing part (310) and a second hinge assembly (342) that rotatably couples the third housing part (330) to the other side of the first housing part (310). The foldable electronic device (300) may have a structure that can be folded twice by the first hinge assembly (341) and the second hinge assembly (342).

[0073] A foldable electronic device (300) according to one embodiment may include a flexible display (350). The flexible display (350) may be disposed on a first housing part (310), a second housing part (320), and a third housing part (330). The flexible display (350) may define a front surface of the foldable electronic device (300). When the foldable housing (301) is folded or unfolded, the flexible display (350) may also be folded or unfolded. For example, the flexible display (350) may include a first bendable portion (351) that may be folded by rotation of the first housing part (310) and rotation of the second housing part (320), and a second bendable portion (352) that may be folded by rotation of the first housing part (310) and rotation of the third housing part (330).

[0074] The first state (300a) of FIG. 3A may be referred to as an unfolded state of the foldable electronic device (300). The first state (300a) corresponds to a state in which the first housing part (310), the second housing part (320), and the third housing part (330) are completely unfolded. Within the unfolded state of the foldable electronic device (300), the first housing part (310), the second housing part (320), and the third housing part (330) may be arranged on substantially the same plane. Within the first state (300a), the first bendable part (351) and the second bendable part (352) may be substantially flat. The first state (300a) may also be referred to as an open state, a flat state, and / or an outspread state, from the perspective that the first housing part (310), the second housing part (320), and the third housing part (330) are fully unfolded. Within the first state (300a), the first housing part (310) may be positioned between the second housing part (320) and the third housing part (330).

[0075] The second state (300b) of FIG. 3a corresponds to a state in which the second housing part (320) is folded relative to the first housing part (310). Within the first state (300a), as the second housing part (320) is rotated relative to the first housing part (310), the foldable electronic device (300) can change from the first state (300a) to the second state (300b). For example, the second housing part (320) can be rotated in a first rotational direction (e.g., counterclockwise) relative to the first housing part (310) by the first hinge assembly (341). When the second housing part (320) is rotated by about 180 degrees, a second state (300b) can be provided in which the second housing part (320) is placed on the first housing part (310). Within the second state (300b), the first bendable portion (351) can be bent. The second state (300b) may be referred to as a sub-unfolded state, a sub-folded state, a half-unfolded state, a half-folded state, and / or an intermediate state.

[0076] The third state (300c) of FIG. 3A may be referred to as a folded state of the foldable electronic device (300). The third state (300c) corresponds to a state in which the first housing part (310), the second housing part (320), and the third housing part (330) are completely folded. In the folded state of the foldable electronic device (300), when the foldable electronic device (300) is viewed from above, the first housing part (310), the second housing part (320), and the third housing part (330) may overlap each other. In the second state (300b), as the third housing part (330) is rotated with respect to the first housing part (310), the foldable electronic device (300) may change from the second state (300b) to the third state (300c). For example, the third housing part (330) can be rotated in a second rotational direction (e.g., clockwise) opposite to the first rotational direction with respect to the first housing part (310) by the second hinge assembly (342). Within the second state (300b), when the third housing part (330) is rotated about 180 degrees, a third state (300c) can be provided in which the third housing part (330) is positioned over the second housing part (320). Within the third state (300c), the first bendable part (351) and the second bendable part (352) can be bent. Within the third state (300c), the flexible display (350) may not be exposed to the outside of the foldable electronic device (300) by being covered by the first housing part (310), the second housing part (320), and / or the third housing part (330). Within the third state (300c), the second housing part (320) may be positioned between the first housing part (310) and the third housing part (330). Within the third state (300c), the cover display (360) disposed on the rear surface of the third housing part (330) may be exposed to the outside.The third state (300c) may also be referred to as a closed state, from the perspective that the first housing part (310), the second housing part (320), and the third housing part (330) are completely folded.

[0077] In one embodiment, the first hinge assembly (341) and the second hinge assembly (342) may be different. For example, within the third state (300c), the width of the second hinge assembly (342) may be wider than the width of the first hinge assembly (341) so that the second housing part (320) may be positioned between the first housing part (310) and the third housing part (330). In view of having different widths, the first hinge assembly (341) may be referred to as a narrow hinge, and the second hinge assembly (342) may be referred to as a wide hinge.

[0078] Referring to FIG. 3b, in the unfolded state of the foldable electronic device (300) (e.g., the first state (300a) of FIG. 3a), the first housing part (310) may be positioned between the second housing part (320) and the third housing part (330). In the folded state of the foldable electronic device (300) (e.g., the third state (300c) of FIG. 3a), the second housing part (320) may be positioned between the first housing part (310) and the third housing part (330).

[0079] A foldable electronic device (300) according to one embodiment may be configured to communicate with an external electronic device using an antenna (e.g., the first antenna (210) and / or the second antenna (220) of FIG. 2). For example, an antenna radiator for transmitting and / or receiving a signal may be formed along a portion of a side surface of a foldable housing (301). For example, the foldable housing (301) may include a plurality of conductive portions and a plurality of non-conductive portions forming at least a portion of a side surface of the foldable housing (301). At least one of the plurality of conductive portions may be configured to function as an antenna radiator for transmitting and / or receiving a signal by being electrically connected to a wireless communication circuit (e.g., the wireless communication circuit (192) of FIG. 2). The plurality of non-conductive portions may separate the conductive portion that operates as the antenna radiator from other conductive portions.

[0080] Referring to FIG. 3B, the first housing part (310) may include a first side surface (311). The first side surface (311) may be a side surface of the first housing part (310) that is substantially perpendicular to a side surface (310a) that is rotatably coupled to a third housing part (330). For example, the side surface (310a) may be positioned along a boundary between the first housing part (310) and the third housing part (330). The side surface (310a) may be rotatably coupled to the second housing part (320) through a first hinge assembly (e.g., the first hinge assembly (341) of FIG. 3A).

[0081] According to one embodiment, the second housing part (320) may include a second side (321). The second side (321) may be parallel to the first side (311) of the first housing part (310) within an unfolded state of the foldable electronic device (300) (e.g., a first state (300a)). The second side (321) may overlap the first side (311) when the foldable electronic device (300) is viewed from above (e.g., in the z-axis direction) within a folded state (e.g., a third state (300c)). For example, within the folded state of the foldable electronic device (300), the second side (321) may be adjacent to the first side (311).

[0082] According to one embodiment, the third housing part (330) may include a third side (331). The third side (331) may be parallel to the first side (311) and the second side (321) within the unfolded state of the foldable electronic device (300). The third side (331) may overlap the first side (311) and the second side (321) when the foldable electronic device (300) in the folded state is viewed from above (e.g., in the z-axis direction). Referring to FIG. 3B, within the unfolded state of the foldable electronic device (300), the first side (311) may be positioned between the second side (321) and the third side (331). Within the folded state of the foldable electronic device (300), the second side (321) may be positioned between the first side (311) and the third side (331). The first side (311), the second side (321), and the third side (331) may face the same direction (e.g., the +y direction).

[0083] According to one embodiment, the first side (311) of the first housing part (310) may include a first conductive portion (411) and a first non-conductive portion (421). For example, the first conductive portion (411) and the first non-conductive portion (421) may form at least a portion of the first side (311). The first non-conductive portion (421) may be in contact with the first conductive portion (411).

[0084] According to one embodiment, the second side (321) may include a second conductive portion (412) and a second non-conductive portion (422). For example, the second conductive portion (412) and the second non-conductive portion (422) may form at least a portion of the second side (321). The second non-conductive portion (422) may be in contact with the second conductive portion (421).

[0085] According to one embodiment, the third side (331) may include a third conductive portion (413) and a third non-conductive portion (423). For example, the third conductive portion (413) and the third non-conductive portion (423) may form at least a portion of the third side (331). The third non-conductive portion (423) may be in contact with the third conductive portion (413).

[0086] As illustrated in FIG. 3B, the first side (311), the second side (321), and the third side (331) are illustrated as being positioned at the upper portion (e.g., in the +y direction) of the foldable housing (301), but the present disclosure is not limited thereto. For example, the first side (311), the second side (321), and the third side (331) may also be positioned at the lower portion (e.g., in the -y direction) of the foldable housing (301).

[0087] According to one embodiment, the first conductive portion (411) and / or the third conductive portion (413) may be configured to function as an antenna radiator. The first conductive portion (411) may include a first feed point electrically connected to a wireless communication circuit (e.g., the wireless communication circuit (192) of FIG. 2) and / or a first ground point electrically connected to the ground of the foldable electronic device (300). For example, when a feed signal is provided from the wireless communication circuit (192) to the first feed point, the first conductive portion (410) may operate as an antenna radiator by forming an electromagnetic field for transmitting and / or receiving a wireless signal. For example, an antenna (e.g., the first antenna (210) of FIG. 2) including at least a portion of the first conductive portion (411) may be configured to function as an antenna for transmitting and / or receiving a first signal on a first frequency band. The first conductive portion (411) may be referred to as a radiator of the first antenna. For example, the ground of the foldable electronic device (300) electrically connected to the first ground point may be referred to as a bracket disposed within the foldable housing (301), but is not limited thereto.

[0088] In one embodiment, the third conductive portion (413) may include a second feed point electrically connected to the wireless communication circuit (192) and / or a second ground point electrically connected to the ground of the foldable electronic device (300). For example, when a feed signal is provided from the wireless communication circuit (192) to the second feed point, the third conductive portion (413) may be configured to function as an antenna radiator by forming an electromagnetic field for transmitting and / or receiving a wireless signal. For example, an antenna (e.g., the second antenna (220) of FIG. 2) including at least a portion of the third conductive portion (413) may operate as an antenna for transmitting and / or receiving a second signal on a second frequency band. The third conductive portion (413) may be referred to as a radiator of the second antenna.

[0089] In one embodiment, the first length (L1) of the first conductive portion (411) may be different from the second length (L2) of the third conductive portion (413). The first length (L1) of the first conductive portion (411) may be referred to as the length from one end of the first conductive portion (411) connected to the second hinge assembly (342) to the other end of the first conductive portion (411) that contacts the first non-conductive portion (421). The second length (L2) of the third conductive portion (413) may be referred to as the length from one end of the third conductive portion (413) connected to the second hinge assembly (342) to the other end of the third conductive portion (413) that contacts the third non-conductive portion (423). For example, the first length (L1) may be longer than the second length (L2). The operating frequency of the antenna can be determined based on the electrical length of the antenna radiator. For example, when the wavelength corresponding to the operating frequency is w, the electrical length of the antenna radiator can be w / 4 to w / 2. Since the first length (L1) is different from the second length (L2), the foldable electronic device (300) can be configured to transmit and / or receive signals in various frequency bands.

[0090] In one embodiment, since the first length (L1) is longer than the second length (L2), the first frequency band may be lower than the second frequency band. For example, the first frequency band may include a low band. For example, the second frequency band may include a mid band, a high band, and / or an ultra-high band. For example, the second frequency band may include a WiFi signal band and / or a GPS signal band. According to one embodiment, the foldable electronic device (300) may be configured to transmit and / or receive signals on various frequency bands using the first antenna and the second antenna. However, the present invention is not limited thereto. For example, the first length (L1) may be substantially equal to the second length (L2).

[0091] According to one embodiment, when the foldable electronic device (300) is viewed from above in a folded state, the first side (311), the second side (321), and the third side (331) may overlap. In the folded state of the foldable electronic device (300), the first conductive portion (411) and the third conductive portion (413), which function as antenna radiators, are adjacent to the second conductive portion (412) of the second side (321), so that the communication performance of the foldable electronic device (300) may be deteriorated. For example, when a power supply signal is provided to the first conductive portion (411) and / or the third conductive portion (413), a flow of radiating current may be formed along the first conductive portion (411) and / or the third conductive portion (413). By the radiated current, an electromagnetic field is formed around the first conductive portion (411) and / or the third conductive portion (413), and signals can be radiated to an external electronic device through the electromagnetic field. When the signals are radiated, since the second conductive portion (412), which is a conductor, blocks the first conductive portion (411) and / or the third conductive portion (413), it may be difficult for the signals to be radiated in the direction blocked by the second conductive portion (412). In the folded state, the communication performance of the foldable electronic device (300) may deteriorate.

[0092] In order to reduce the deterioration of the above communication performance, the second non-conductive portion (422) may be arranged in relation to each of the first non-conductive portion (421) and the third non-conductive portion (423) within the second side (321). According to one embodiment, when viewed in a direction perpendicular to the rear surface of the foldable housing (301) (e.g., in the z-axis direction) within the foldable electronic device (300) in a folded state, both ends of the second non-conductive portion (422) may be arranged to overlap with the ends of the first non-conductive portion (421) and the third non-conductive portion (423), respectively. According to one embodiment, when signals are radiated through the first conductive portion (411) and / or the third conductive portion (413), a strong electric field may be formed in the first non-conductive portion (421) and / or the third non-conductive portion (423). The second non-conductive portion (422) is positioned adjacent to or overlapping the first non-conductive portion (421) and / or the third non-conductive portion (423) where a strong electric field is formed, thereby reducing the effect of blocking signals radiated from the first conductive portion (411) and / or the third conductive portion (413) and assisting in the formation of the electric field.

[0093] In one embodiment, if the second non-conductive portion (422) is arranged to overlap only one of the first non-conductive portion (421) or the third non-conductive portion (423), the communication performance of either the first antenna or the second antenna may be improved, but it may be difficult to expect improvement in the communication performance of the other antenna. For example, if the second non-conductive portion (422) is arranged to overlap only the first non-conductive portion (421), the communication performance of the first antenna may be improved, but the communication performance of the second antenna is not improved.

[0094] According to one embodiment, a foldable electronic device (300) may have a structure for improving both the communication performance of the first antenna and the communication performance of the second antenna in a folded state of the foldable electronic device (300). When the first length (L1) and the second length (L2) are different, the first non-conductive portion (421) may not be positioned on the same line as the third non-conductive portion (423). According to one embodiment, the second non-conductive portion (422) may be positioned to overlap the first end (421a) of the first non-conductive portion (421) and the first end (423a) of the third non-conductive portion (423), respectively, when viewed in a direction perpendicular to the rear surface of the foldable housing (301).

[0095] Referring to FIG. 3c, a folded state of the foldable electronic device (300) is illustrated (e.g., the third state (300c) of FIG. 3a). As described above, in the folded state of the foldable electronic device (300), the second housing part (320) may be positioned between the first housing part (310) and the third housing part (330).

[0096] Referring to FIG. 3C, the first non-conductive portion (421) may extend from a first end (421a) facing the second housing part (320) to a second end (421b) opposite the first end (421a) in a folded state of the foldable electronic device (300). The second non-conductive portion (422) may extend from a first end (422a) facing the first housing part (310) to a second end (422b) opposite the first end (422a) in a folded state of the foldable electronic device (300). The third non-conductive portion (423) may extend from a first end (423a) facing the second housing part (320) to a second end (423b) opposite the first end (423a) in a folded state of the foldable electronic device (300).

[0097] According to one embodiment, in the folded state of the foldable electronic device (300), the first end (421a) of the first non-conductive portion (421) facing the second housing part (320) and the first end (422a) of the second non-conductive portion (422) facing the first housing part (310) may be arranged close to each other.

[0098] According to one embodiment, in the folded state of the foldable electronic device (300), the second end (421b) of the first non-conductive portion (421) and the second end (422b) of the second non-conductive portion (422) may be positioned far from each other.

[0099] According to one embodiment, in the folded state of the foldable electronic device (300), the second end (422b) of the second non-conductive portion (422) and the first end (423a) of the third non-conductive portion (423) may be arranged close to each other.

[0100] According to one embodiment, in the folded state of the foldable electronic device (300), the first end (422a) of the second non-conductive portion (422) and the second end (423b) of the third non-conductive portion (423) may be positioned far from each other.

[0101] According to one embodiment, the first end (421a) of the first non-conductive portion (421) may be disposed on a first virtual line (V1) extending in a direction perpendicular to the rear surface of the first housing part (310) (e.g., in the z-axis direction) when the foldable electronic device (300) is in a folded state. According to one embodiment, at least a portion of the first non-conductive portion (421) between the first end (421a) of the first non-conductive portion (421) and the second end (421b) of the first non-conductive portion (421) or at least a portion of the second non-conductive portion (422) between the first end (422a) of the second non-conductive portion (422) and the second end (422b) of the second non-conductive portion (422) may not be disposed on the first virtual line (V1) when the foldable electronic device (300) is in a folded state. Here, the first virtual line (V1) may be a line passing through the first end (421a) of the first non-conductive portion (421) among the virtual lines extending in a direction perpendicular to the rear surface of the first housing part (310). In the case of the example illustrated in FIG. 3c, the first non-conductive portion (421) is disposed on the first virtual line (V1), but at least a part of the second non-conductive portion (422) is not disposed on the first virtual line (V1), thereby satisfying the above structure.

[0102] According to one embodiment, the second end (422b) of the second non-conductive portion (422) may be disposed on a fourth virtual line (V4) extending in a direction perpendicular to the rear surface (e.g., in the z-axis direction) of the second housing part (320) in a folded state of the foldable electronic device (300). According to one embodiment, at least a portion of the second non-conductive portion (422) between the first end (422a) of the second non-conductive portion (422) and the second end (422b) of the second non-conductive portion (422) or at least a portion of the third non-conductive portion (423) between the first end (423a) of the third non-conductive portion (423) and the second end (423b) of the third non-conductive portion (423) may not be disposed on the fourth virtual line (V4). Here, the fourth virtual line (V4) may be a line passing through the first end (423a) of the third non-conductive portion (423) among the virtual lines extending in a direction perpendicular to the rear surface of the first housing part (310). In the case of the embodiment illustrated in FIG. 3c, the third non-conductive portion (423) is disposed on the fourth virtual line (V4), but since at least a portion of the second non-conductive portion (422) is not disposed on the fourth virtual line (V4), the above structure may be satisfied.

[0103] For example, in a folded state of the foldable electronic device (300), a first end (422a) of the second non-conductive portion (422) may be disposed on a first virtual line (V1), and at least a portion of the second non-conductive portion (422) between the first end (422a) and the second end (422b) may not be disposed on the first virtual line (V1). In a folded state of the foldable electronic device (300), a second end (422b) of the second non-conductive portion (422) may be disposed on a fourth virtual line (V4), and at least a portion of the second non-conductive portion (422) between the first end (422a) and the second end (422b) may not be disposed on the fourth virtual line (V4).

[0104] Referring to FIG. 3D, the foldable electronic device (300) may further include a fourth non-conductive portion (424), a fifth non-conductive portion (425), and a sixth non-conductive portion (426).

[0105] According to one embodiment, the first side (311) may further include a fourth non-conductive portion (424). For example, the first conductive portion (411) may be disposed between the first non-conductive portion (421) and the fourth non-conductive portion (424). The first non-conductive portion (421) may contact one end (411a) of the first conductive portion (411), and the fourth non-conductive portion (424) may contact the other end (411b) of the first conductive portion (411). For example, the first length (L1) of the first conductive portion (411) may correspond to the distance between the first non-conductive portion (421) and the fourth non-conductive portion (424).

[0106] According to one embodiment, the second side (321) may further include a fifth non-conductive portion (425). For example, the second conductive portion (412) may be disposed between the second non-conductive portion (422) and the fifth non-conductive portion (425). The second non-conductive portion (422) may contact one end (412a) of the second conductive portion (412), and the fifth non-conductive portion (425) may contact the other end (412b) of the second conductive portion (412).

[0107] According to one embodiment, the third side (331) may further include a sixth non-conductive portion (426). For example, the third conductive portion (413) may be disposed between the third non-conductive portion (423) and the sixth non-conductive portion (426). The third non-conductive portion (423) may contact one end (413a) of the third conductive portion (413), and the sixth non-conductive portion (426) may contact the other end (413b) of the third conductive portion (413). For example, the second length (L2) of the third conductive portion (413) may correspond to the distance between the third non-conductive portion (423) and the sixth non-conductive portion (426).

[0108] The first length (L1) may be different from the second length (L2). When the first length (L1) is different from the second length (L2), the first non-conductive portion (421) may be misaligned with the third non-conductive portion (423), and the fourth non-conductive portion (424) may be misaligned with the sixth non-conductive portion (426). Since the first length (L1) is different from the second length (L2), the operating frequency of the antenna including the first conductive portion (411) may be different from the operating frequency of the antenna including the third conductive portion (413).

[0109] According to one embodiment, the arrangement structure of the fourth non-conductive portion (424), the fifth non-conductive portion (425), and the sixth non-conductive portion (426) may correspond to the arrangement structure of the first non-conductive portion (421), the second non-conductive portion (422), and the third non-conductive portion (423).

[0110] Referring to FIG. 3D, the fourth non-conductive portion (424) may extend, in a folded state of the foldable electronic device (300), from a first end (424a) facing the second housing part (320) to a second end (424b) opposite the first end (424a). The fifth non-conductive portion (425) may extend, in a folded state, from a first end (425a) facing the first housing part (310) to a second end (425b) opposite the first end (425a). The third non-conductive portion (426) may extend, in a folded state, from a first end (426a) facing the second housing part (320) to a second end (426b) opposite the first end (426a).

[0111] According to one embodiment, the first end (424a) of the fourth non-conductive portion (424) may be disposed on a sixth virtual line (V6) extending in a direction perpendicular to the rear surface (e.g., in the z-axis direction) of the first housing part (310) in a folded state of the foldable electronic device (300). According to one embodiment, at least a portion of the fourth non-conductive portion (424) between the first end (424a) of the fourth non-conductive portion (424) and the second end (424b) of the fourth non-conductive portion (424) or at least a portion of the fifth non-conductive portion (425) between the first end (425a) of the fifth non-conductive portion (425) and the second end (425b) of the fifth non-conductive portion (425) may not be disposed on the sixth virtual line (V6) in a folded state of the foldable electronic device (300). The sixth virtual line (V6) may be a line passing through the first end (424a) of the fourth non-conductive portion (424) among the virtual lines extending in a direction perpendicular to the rear surface of the first housing part (310).

[0112] According to one embodiment, the second end (425b) of the fifth non-conductive portion (425) may be disposed on a tenth virtual line (V10) extending in a direction perpendicular to the rear surface of the second housing part (320) (e.g., in the z-axis direction) when the foldable electronic device (300) is in a folded state. According to one embodiment, at least a portion of the fifth non-conductive portion (425) between the first end (425a) of the fifth non-conductive portion (425) and the second end (425b) of the fifth non-conductive portion (425) or at least a portion of the sixth non-conductive portion (426) between the first end (426a) of the sixth non-conductive portion (426) and the second end (426b) of the sixth non-conductive portion (426) may not be disposed on the tenth virtual line (V10). The tenth virtual line (V10) may be a line passing through the first end (426a) of the sixth non-conductive portion (426) among the virtual lines extending in a direction perpendicular to the rear surface of the first housing part (310).

[0113] For example, in a folded state of the foldable electronic device (300), a first end (425a) of the fifth non-conductive portion (425) may be disposed on a sixth virtual line (V6), and at least a portion of the fifth non-conductive portion (425) between the first end (425a) and the second end (425b) may not be disposed on the sixth virtual line (V6). In a folded state of the foldable electronic device (300), a second end (425b) of the fifth non-conductive portion (425) may be disposed on a tenth virtual line (V10), and at least a portion of the fifth non-conductive portion (425) between the first end (425a) and the second end (425b) may not be disposed on the tenth virtual line (V10).

[0114] By the second non-conductive portion (422) and / or the fifth non-conductive portion (425) satisfying the above structure, when the first conductive portion (411) and / or the third conductive portion (413) radiates signals, the distribution of the electric field is strongly concentrated in the portion in contact with the non-conductive portions (421, 423), thereby improving the efficiency of the first antenna and / or the efficiency of the second antenna. Hereinafter, examples of the first non-conductive portion (421), the second non-conductive portion (422), and the third non-conductive portion (423) according to various embodiments are described.

[0115] According to one embodiment, the first non-conductive portion (421) may be symmetrical with respect to the fourth non-conductive portion (424) with respect to the central portion of the first housing part (310). The second non-conductive portion (422) may be symmetrical with respect to the fifth non-conductive portion (425) with respect to the central portion of the second housing part (320). The third non-conductive portion (423) may be symmetrical with respect to the sixth non-conductive portion (426) with respect to the central portion of the third housing part (330).

[0116] FIG. 3e illustrates a foldable electronic device according to one embodiment including a paint layer.

[0117] A foldable electronic device (300) according to one embodiment may include a paint layer disposed on a first side (311), a second side (321), and a third side (331). The paint layer is referenced by hatching displayed within the first side (311), the second side (321), and the third side (331) in FIG. 3E . The paint layer may be used to enhance the aesthetics of the foldable electronic device (300) by being visible from the outside of the foldable electronic device (300). For example, the aesthetics of the foldable electronic device (300) may be damaged by a structure in which the non-conductive portions (421, 422, 423, 424, 425, 426) are not arranged parallel to each other. According to one embodiment, the paint layer can cover the first side (311), the second side (321), and the third side (331), thereby hiding the conductive portions (411, 412, 413) and the non-conductive portions (421, 422, 423, 424, 425, 426) from the outside.

[0118] According to one embodiment, the paint layer can improve the appearance of the foldable electronic device (300) by having a pattern or the like on the surface exposed to the outside. The paint layer can cover both the conductive portions (411, 412, 413) and the non-conductive portions (421, 422, 423, 424, 425, 426), or can have an aligned pattern that is visible from the outside. For example, although the non-conductive portions (421, 422, 423, 424, 425, 426) disposed under the paint layer cannot be recognized from the outside, the user can recognize that the aligned non-conductive portions are disposed due to the aligned pattern of the paint layer. In one embodiment, the second conductive portion (412) can be replaced with a portion (412') including a non-conductive material.

[0119] FIGS. 4A, 4B, 4C, and 4D illustrate foldable electronic devices according to various embodiments.

[0120] Referring to FIG. 4A, in the folded state of the foldable electronic device (300), the second housing part (320) may be positioned between the first housing part (310) and the third housing part (330). When the foldable electronic device (300) in the folded state is viewed from above (e.g., in the z-axis direction, the thickness direction of the foldable electronic device (300), or the direction in which the display faces), the first conductive part (411), the second conductive part (412), and the third conductive part (413) may at least partially overlap.

[0121] According to one embodiment, the foldable housing (301) may include various structures satisfying the structures described with reference to FIGS. 3C and 3D. In the embodiments illustrated in FIGS. 4A to 4D, in order to reduce the degradation of the aforementioned communication performance, a first end (422a) of the second non-conductive portion (422) may overlap a first end (421a) of the first non-conductive portion (421) when viewed in a direction perpendicular to the rear surface of the foldable housing (301). A second end (422b) of the second non-conductive portion (422) may overlap a first end (423a) of the third non-conductive portion (423) when viewed in the above direction. The first end (425a) of the fifth non-conductive portion (425) may overlap the first end (424a) of the fourth non-conductive portion (424) when viewed in the above direction. The second end (425b) of the fifth non-conductive portion (425) may overlap the first end (426a) of the sixth non-conductive portion (426) when viewed in the above direction.

[0122] Referring to FIG. 4A, in a folded state of the foldable electronic device (300), the first non-conductive portion (421) and the second non-conductive portion (422) may be arranged such that a second virtual line (V2) extending from the first non-conductive portion (421) is different from a third virtual line (V3) extending from the second non-conductive portion (422). The second virtual line (V2) may be referred to as a virtual line passing through both ends (421a, 421b) of the first non-conductive portion (421). The third virtual line (V3) may be referred to as a virtual line passing through both ends (422a, 422b) of the second non-conductive portion (422). The second virtual line (V2) may be a virtual line passing through the centers of both ends (421a, 421b) of the first non-conductive portion (421). The third virtual line (V3) may be referred to as a virtual line passing through the centers of both ends (422a, 422b) of the second non-conductive portion (422). The second virtual line (V2) may be a virtual line parallel to the longest edge of the first non-conductive portion (421). The third virtual line (V3) may be a virtual line parallel to the longest edge of the second non-conductive portion (422). In the folded state of the foldable electronic device (300), the second non-conductive portion (422) and the third non-conductive portion (423) may be arranged such that the third virtual line (V3) extending from the second non-conductive portion (422) is different from the fifth virtual line (V5) extending from the third non-conductive portion (423). The fifth virtual line (V5) may be referred to as a virtual line passing through both ends (423a, 423b) of the third non-conductive portion (423). The fifth virtual line (V5) may be a virtual line passing through the centers of the both ends (423a, 423b) of the third non-conductive portion (423). The fifth virtual line (V5) may be a virtual line parallel to the longest edge of the third non-conductive portion (423).

[0123] According to one embodiment, the first non-conductive portion (421) and the second non-conductive portion (422) may not extend parallel to each other. For example, a slope may be formed between the first non-conductive portion (421) and the second non-conductive portion (422). According to one embodiment, in a folded state of the foldable electronic device (300), one of the first non-conductive portion (421) and the second non-conductive portion (422) may extend parallel to a first virtual line (V1) extending in a direction perpendicular to the rear surface of the foldable housing (301) (e.g., in the z-axis direction), and the other may extend at an angle to the first virtual line (V1). For example, as illustrated in FIG. 4A, the first non-conductive portion (421) may extend parallel to the first virtual line (V1), and the second non-conductive portion (422) may extend so as to be inclined to the first virtual line (V1). In this case, the second virtual line (V2) may correspond to the first virtual line (V1).

[0124] Referring to FIG. 4A, the foldable electronic device (300) may further include a fourth non-conductive portion (424), a fifth non-conductive portion (425), and a sixth non-conductive portion (426). In a folded state of the foldable electronic device (300), the fourth non-conductive portion (424) and the fifth non-conductive portion (425) may be arranged such that a seventh virtual line (V7) extending from the fourth non-conductive portion (424) is different from an eighth virtual line (V8) extending from the fifth non-conductive portion (425). The seventh virtual line (V7) may be referred to as a virtual line passing through both ends (424a, 424b) of the fourth non-conductive portion (424). The eighth virtual line (V8) may be referred to as a virtual line passing through both ends (425a, 425b) of the fifth non-conductive portion (425). In the folded state of the foldable electronic device (300), the fifth non-conductive portion (425) and the sixth non-conductive portion (426) may be arranged such that the eighth virtual line (V8) extending from the fifth non-conductive portion (425) is different from the ninth virtual line (V9) extending from the sixth non-conductive portion (426). The ninth virtual line (V9) may be referred to as a virtual line passing through both ends (426a, 426b) of the sixth non-conductive portion (426).

[0125] According to one embodiment, the fourth non-conductive portion (424) and the fifth non-conductive portion (425) may not extend in parallel. For example, a slope may be formed between the fourth non-conductive portion (424) and the fifth non-conductive portion (425). According to one embodiment, in a folded state of the foldable electronic device (300), one of the fourth non-conductive portion (424) and the fifth non-conductive portion (425) may extend parallel to a sixth virtual line (V6) extending in a direction perpendicular to the rear surface of the foldable housing (301) (e.g., in the z-axis direction), and the other may extend at an angle to the sixth virtual line (V6). For example, in the embodiment illustrated in FIG. 4A, the fourth non-conductive portion (424) may extend parallel to the sixth virtual line (V6), and the fifth non-conductive portion (425) may extend so as to be inclined to the sixth virtual line (V6). In this case, the seventh virtual line (V7) may correspond to the sixth virtual line (V6).

[0126] According to one embodiment, the first conductive portion (411) and / or the third conductive portion (413) may be configured to function as an antenna radiator. Since the length of the first conductive portion (411) is different from the length of the third conductive portion (413), the operating frequency of the antenna including the first conductive portion (411) and the operating frequency of the antenna including the third conductive portion (413) may be different. Signals (e.g., radio frequency (RF) signals) radiated through the first conductive portion (411) and / or the third conductive portion (413) may be blocked by the second conductive portion (412) between the first conductive portion (411) and the third conductive portion (413) in the folded state of the foldable electronic device (300). The second non-conductive portion (422) may be disposed adjacent to or overlapping the first non-conductive portion (421) and / or the third non-conductive portion (423) where a strong electric field is formed. The fifth non-conductive portion (425) may be disposed adjacent to or overlapping the fourth non-conductive portion (424) and / or the sixth non-conductive portion (426) where a strong electric field is formed. Through the second non-conductive portion (422) and the fifth non-conductive portion (425) in contact with the second conductive portion (412), the effect of the second conductive portion (412) blocking signals radiated from the first conductive portion (411) and / or the third conductive portion (413) may be reduced.

[0127] Referring to FIG. 4B, the first non-conductive portion (421) and the second non-conductive portion (422) may be arranged such that a second virtual line (V2) extending from the first non-conductive portion (421) is parallel to a third virtual line (V3) extending from the second non-conductive portion (422). In this case, the first non-conductive portion (421) and the second non-conductive portion (422) may extend in the same direction.

[0128] According to one embodiment, the first non-conductive portion (421) and the second non-conductive portion (422) may be arranged such that, when the foldable electronic device (300) is in a folded state, a first virtual line (V1) extending in a direction perpendicular to the rear surface of the foldable housing (301) (e.g., in the z-axis direction) does not coincide with one of the second virtual line (V2) and the third virtual line (V3). For example, at least one of the first non-conductive portion (421) and the second non-conductive portion (422) may be arranged to have an incline with respect to the first virtual line (V1).

[0129] Referring to FIG. 4B, the second non-conductive portion (422) and the third non-conductive portion (423) may be arranged such that a third virtual line (V3) extending from the second non-conductive portion (422) is parallel to a fifth virtual line (V5) extending from the third non-conductive portion (423). In this case, the first non-conductive portion (421), the second non-conductive portion (422), and the third non-conductive portion (423) may extend in the same direction, and the second virtual line (V2), the third virtual line (V3), and the fifth virtual line (V5) may be substantially the same.

[0130] According to one embodiment, the second non-conductive portion (422) and the third non-conductive portion (423) may be arranged such that, when the foldable electronic device (300) is in a folded state, a first virtual line (V1) extending in a direction perpendicular to the rear surface of the foldable housing (301) (e.g., in the z-axis direction) does not coincide with one of the third virtual line (V3) and the fifth virtual line (V5). For example, at least one of the second non-conductive portion (422) and the third non-conductive portion (423) may be arranged to have an incline with respect to the first virtual line (V1).

[0131] Referring to FIG. 4b, the foldable electronic device (300) may further include a fourth non-conductive portion (424), a fifth non-conductive portion (425), and a sixth non-conductive portion (426).

[0132] According to one embodiment, the fourth non-conductive portion (424) and the fifth non-conductive portion (425) may be arranged such that a seventh virtual line (V7) extending from the fourth non-conductive portion (424) is parallel to an eighth virtual line (V8) extending from the fifth non-conductive portion (425). In this case, the fourth non-conductive portion (424) and the fifth non-conductive portion (425) may extend in the same direction.

[0133] According to one embodiment, the fourth non-conductive portion (424) and the fifth non-conductive portion (425) may be arranged such that a sixth virtual line (V6) extending in a direction perpendicular to the rear surface of the foldable housing (301) (e.g., in the z-axis direction) when the foldable electronic device (300) is in a folded state does not coincide with one of the seventh virtual line (V7) and the eighth virtual line (V8). For example, at least one of the fourth non-conductive portion (424) and the fifth non-conductive portion (425) may be arranged to have an incline with respect to the sixth virtual line (V6).

[0134] Referring to FIG. 4B, the fifth non-conductive portion (425) and the sixth non-conductive portion (426) may be arranged such that an eighth virtual line (V8) extending from the fifth non-conductive portion (425) is parallel to a ninth virtual line (V9) extending from the sixth non-conductive portion (426). In this case, the fourth non-conductive portion (424), the fifth non-conductive portion (425), and the sixth non-conductive portion (426) may extend in the same direction, and the seventh virtual line (V7), the eighth virtual line (V8), and the ninth virtual line (V9) may be substantially the same.

[0135] According to one embodiment, the fifth non-conductive portion (425) and the sixth non-conductive portion (426) may be arranged such that, when the foldable electronic device (300) is in a folded state, a sixth virtual line (V6) extending in a direction perpendicular to the rear surface of the foldable housing (301) (e.g., in the z-axis direction) does not coincide with one of the eighth virtual line (V8) and the ninth virtual line (V9). For example, at least one of the fifth non-conductive portion (425) and the sixth non-conductive portion (426) may be arranged to have an incline with respect to the sixth virtual line (V6).

[0136] In the embodiment illustrated in FIG. 4b, the first non-conductive portion (421), the second non-conductive portion (422), and the third non-conductive portion (423) can be inclined with respect to the first virtual line (V1) and can be parallel to each other. In one embodiment, the fourth non-conductive portion (424), the fifth non-conductive portion (425), and the sixth non-conductive portion (426) can be inclined with respect to the sixth virtual line (V6) and can be parallel to each other.

[0137] Within FIG. 4b, the first non-conductive portion (421), the second non-conductive portion (422), and the third non-conductive portion (423) are described as extending in parallel, and the fourth non-conductive portion (424), the fifth non-conductive portion (425), and the sixth non-conductive portion (426) are described as extending in parallel, but are not limited thereto.

[0138] Referring to FIG. 4C, the first non-conductive portion (421) and the second non-conductive portion (422) may extend parallel, and the third non-conductive portion (423) may extend non-parallel to the first non-conductive portion (421) and the second non-conductive portion (422). The fourth non-conductive portion (424) and the fifth non-conductive portion (425) may extend parallel, and the sixth non-conductive portion (426) may extend non-parallel to the fourth non-conductive portion (424) and the fifth non-conductive portion (425).

[0139] Referring to FIG. 4C, the first non-conductive portion (421), the second non-conductive portion (422), and the third non-conductive portion (423) may extend to be inclined with respect to the first virtual line (V1). The direction in which the first non-conductive portion (421) and the second non-conductive portion (422) extend and the direction in which the third non-conductive portion (423) extend may be different from each other. For example, the second virtual line (V2) extending from the first non-conductive portion (421) may be parallel to the third virtual line (V3) extending from the second non-conductive portion (422), and may form an inclined angle with the fifth virtual line (V5) extending from the third non-conductive portion (423).

[0140] According to one embodiment, the fourth non-conductive portion (424), the fifth non-conductive portion (425), and the sixth non-conductive portion (426) can extend so as to be inclined with respect to the sixth virtual line (V6). The directions in which the fourth non-conductive portion (424) and the fifth non-conductive portion (425) extend and the direction in which the sixth non-conductive portion (426) extend may be different from each other. For example, the seventh virtual line (V7) extending from the fourth non-conductive portion (424) can be parallel to the eighth virtual line (V8) extending from the fifth non-conductive portion (425) and can form an inclined direction with the ninth virtual line (V9) extending from the sixth non-conductive portion (426).

[0141] Referring to FIG. 4D, in a folded state of the foldable electronic device (300), one of the first non-conductive portion (421) and the second non-conductive portion (422) may extend parallel to a first virtual line (V1) extending in a direction perpendicular to the rear surface of the foldable housing (301) (e.g., in the z-axis direction), and the other may extend at an angle to the first virtual line (V1). For example, the first non-conductive portion (421) may extend at an angle to the first virtual line (V1), and the second non-conductive portion (422) may extend parallel to the first virtual line (V1). A second virtual line (V2) extending from the first non-conductive portion (421) may be inclined to the first virtual line (V1), and a third virtual line (V3) extending from the second non-conductive portion (422) may be parallel to the first virtual line (V1).

[0142] According to one embodiment, in a folded state of the foldable electronic device (300), one of the second non-conductive portion (422) and the third non-conductive portion (423) may extend parallel to a first virtual line (V1) extending in a direction perpendicular to the rear surface of the foldable housing (301) (e.g., in the z-axis direction), and the other may extend at an angle to the first virtual line (V1). For example, the third non-conductive portion (423) may extend at an angle to the first virtual line (V1), and the second non-conductive portion (422) may extend parallel to the first virtual line (V1). The first virtual line (V1) may form an angle with a fifth virtual line (V5) extending from the third non-conductive portion (423).

[0143] Referring to FIG. 4d, the foldable electronic device (300) may further include a fourth non-conductive portion (424), a fifth non-conductive portion (425), and a sixth non-conductive portion (426).

[0144] Referring to FIG. 4D, in the folded state of the foldable electronic device (300), one of the fourth non-conductive portion (424) and the fifth non-conductive portion (425) may extend parallel to a sixth virtual line (V6) extending in a direction perpendicular to the rear surface of the foldable housing (301) (e.g., in the z-axis direction), and the other may extend at an angle to the sixth virtual line (V6). For example, the fourth non-conductive portion (424) may extend at an angle to the sixth virtual line (V6), and the fifth non-conductive portion (425) may extend parallel to the sixth virtual line (V6). A seventh virtual line (V7) extending from the fourth non-conductive portion (424) may be inclined to the sixth virtual line (V6), and an eighth virtual line (V8) extending from the fifth non-conductive portion (422) may be parallel to the sixth virtual line (V6).

[0145] According to one embodiment, in a folded state of the foldable electronic device (300), one of the fifth non-conductive portion (425) and the sixth non-conductive portion (426) may extend parallel to a sixth virtual line (V6) extending in a direction perpendicular to the rear surface of the foldable housing (301) (e.g., in the z-axis direction), and the other may extend at an angle to the sixth virtual line (V6). For example, the sixth non-conductive portion (426) may extend at an angle to the sixth virtual line (V6), and the fifth non-conductive portion (425) may extend parallel to the sixth virtual line (V6). The sixth virtual line (V6) may form an angle with a ninth virtual line (V9) extending from the sixth non-conductive portion (426).

[0146] The examples illustrated in FIGS. 4a, 4b, 4c, and 4d are structures that satisfy the structure described with reference to FIGS. 3c and 3d, and are structures that can reduce interference by the second conductive portion (412) when the first conductive portion (411) and / or the third conductive portion (413) operates as an antenna radiator.

[0147] FIG. 4e illustrates a foldable electronic device according to a comparative example.

[0148] Referring to FIG. 4e, an example of a foldable electronic device (400) according to a comparative example that does not satisfy the above structure is described.

[0149] In the example illustrated in FIG. 4e, in the folded state of the foldable electronic device (300), the first end (421a) of the first non-conductive portion (421) and the first end (422a) of the second non-conductive portion (422) may be arranged to overlap each other when viewed in a direction perpendicular to the rear surface of the foldable housing (301) (e.g., in the z-axis direction). The second end (422b) of the second non-conductive portion (422) and the first end (423a) of the third non-conductive portion (423) may be arranged to not overlap each other when viewed in a direction perpendicular to the rear surface of the foldable housing (301) (e.g., in the z-axis direction). For example, in the folded state of the foldable electronic device (300), the first end (424a) of the fourth non-conductive portion (424) and the first end (425a) of the fifth non-conductive portion (425) may be arranged to overlap each other when viewed in a direction perpendicular to the rear surface of the foldable housing (301), but the second end (425b) of the fifth non-conductive portion (425) and the first end (426a) of the sixth non-conductive portion (426) may be arranged to not overlap each other. The example illustrated in FIG. 4e does not satisfy the structures of FIGS. 3c and 3d, and therefore, in the folded state of the foldable electronic device (300), when the third conductive portion (413) operates as an antenna radiator, the second conductive portion (412) may block the radiation of signals and interfere with the signals. In this case, the communication performance of the foldable electronic device (400) according to the comparative example may be deteriorated by the second conductive portion (412).

[0150] A foldable electronic device (300) according to one embodiment may include a foldable housing (301) of a segmented structure that satisfies the structure described with reference to FIGS. 3c and 3d, such as the foldable housing (301) illustrated in FIGS. 4a, 4b, 4c, and 4d.

[0151] FIG. 5A illustrates electric fields formed from a first antenna of an electronic device according to one embodiment and a first antenna of an electronic device according to a comparative example. FIG. 5B illustrates electric fields formed from a second antenna of an electronic device according to one embodiment and a second antenna of an electronic device according to a comparative example. FIG. 5C is a graph showing the efficiency of the first antenna and the efficiency of the second antenna.

[0152] Referring to FIG. 5A, a foldable electronic device (300) according to one embodiment may include a foldable housing (301) having a structure described with reference to FIGS. 3C and 3D. At least a portion of a first conductive portion (411) forming at least a portion of a first side (311) may function as a radiator of a first antenna.

[0153] When comparing the housing (501) of the foldable electronic device (500) according to the comparative example with the foldable housing (301) according to one embodiment, the housing (501) may not include the second non-conductive portion (422) and / or the fifth non-conductive portion (425), or the ends of the non-conductive portions within the second side (504) may not overlap the ends of the non-conductive portions within the first side (502) and the ends of the non-conductive portions within the third side (506), respectively. A structure in which both ends of the non-conductive portions of the second side (504) do not overlap with each of the ends of the non-conductive portions in the first side (502) and each of the ends of the non-conductive portions in the third side (506) may be referred to as a structure in which neither of the ends of the non-conductive portions in the second side (504) overlaps with either the ends of the non-conductive portions in the first side (502) and the ends of the non-conductive portions in the third side (506), or overlaps only one of the ends of the non-conductive portions in the first side (502) and the ends of the non-conductive portions in the third side (506). At least a part of the first conductive portion (503) forming at least a part of the first side (502) may act as a radiator of the first antenna.

[0154] According to one embodiment, a wireless communication circuit (e.g., a wireless communication circuit (192) of FIG. 2) can power a first feed point of a first conductive portion (411, 503). When a feed signal is fed to the first feed point, a radiating current can be formed along at least a portion of the first conductive portion (411, 503). The radiating current can form an electric field in the housing (301, 501). The first conductive portion (411, 503) can be configured to radiate a first signal on a first frequency band based on the feeding by the wireless communication circuit (192). As the strength of the electric field formed in the housing (301, 501) increases, a signal that is reflected and not radiated through at least a portion of the first conductive portion (411, 503) is reduced, thereby improving the efficiency of the first antenna.

[0155] Referring to FIG. 5A, a first electric field (51) formed in a foldable housing (301) of a foldable electronic device (300) according to an embodiment may be formed to be stronger than a second electric field (52) formed in a housing (501) of a foldable electronic device (500) according to a comparative example. In the case of the foldable electronic device (500) according to the comparative example, a second electric field (52) that is weaker than the first electric field (51) may be formed because the third side (506) adjacent to the first conductive portion (503) does not include a non-conductive portion, or because both ends of the non-conductive portions of the second side (504) do not overlap with the ends of the non-conductive portions in the first side (502) and the ends of the non-conductive portions in the third side (506), respectively. In the case of the foldable electronic device (300) according to one embodiment, the effect of the second conductive portion (412) blocking the first conductive portion (411) may be reduced by the first non-conductive portion (421), the second non-conductive portion (422), the fourth non-conductive portion (424), and the fifth non-conductive portion (425). The first electric field (51) may be formed to be strong by the first non-conductive portion (421), the second non-conductive portion (422), the fourth non-conductive portion (424), and the fifth non-conductive portion (425). Since the strength of the first electric field (51) is stronger than the strength of the second electric field (52), the efficiency of the first antenna of the foldable electronic device (300) according to one embodiment may be higher than the efficiency of the first antenna of the foldable electronic device (500) according to the comparative example.

[0156] Referring to FIG. 5b, at least a portion of the third conductive portion (413) forming at least a portion of the third side (331) can operate as a radiator of the second antenna. At least a portion of the second conductive portion (413) forming at least a portion of the third side (331) can operate as a radiator of the second antenna.

[0157] According to one embodiment, a wireless communication circuit (e.g., a wireless communication circuit (192) of FIG. 2) can power a second feed point of a third conductive portion (413). When a feed signal is powered to the second feed point, a radiating current can be formed along at least a portion of the third conductive portion (413). The radiating current can form an electric field in the foldable housing (301). The third conductive portion (413) can be configured to radiate a second signal on a second frequency band based on the power supply by the wireless communication circuit (192). As the strength of the electric field formed in the foldable housing (301) increases, a signal that is reflected and not radiated through at least a portion of the third conductive portion (413) is reduced, thereby improving the efficiency of the second antenna.

[0158] Referring to FIG. 5B, a third electric field (53) formed in a foldable housing (301) of a foldable electronic device (300) according to an embodiment may be formed to be stronger than a fourth electric field (54) formed in a housing (501) of a foldable electronic device (500) according to a comparative example. In the case of the foldable electronic device (500) according to the comparative example, a fourth electric field (54) that is weaker than the third electric field (53) may be formed because the third side (506) adjacent to the third conductive part (505) does not include a non-conductive part, or because both ends of the non-conductive parts of the second side (504) do not overlap with the ends of the non-conductive parts in the first side (502) and the ends of the non-conductive parts in the third side (506), respectively. In the case of the foldable electronic device (300) according to one embodiment, the effect of the second conductive portion (412) blocking the third conductive portion (413) may be reduced by the second non-conductive portion (422), the third non-conductive portion (423), the fifth non-conductive portion (425), and the sixth non-conductive portion (426). A third electric field (53) may be strongly formed in the second non-conductive portion (422), the third non-conductive portion (423), the fifth non-conductive portion (425), and the sixth non-conductive portion (426). Since the intensity of the third electric field (53) is stronger than the intensity of the fourth electric field (54), the efficiency of the second antenna of the foldable electronic device (300) according to one embodiment may be higher than the efficiency of the second antenna of the foldable electronic device (500) according to the comparative example.

[0159] Referring to FIG. 5c, the efficiency of the antenna of the foldable electronic device (300) according to one embodiment and the efficiency of the antenna according to a comparative example can be compared. The x-axis of the graph of FIG. 5c represents the frequency (unit: GHz), and the y-axis represents the efficiency of the antenna (unit: dB).

[0160] The first graph (510) of FIG. 5C represents the efficiency of the first antenna in the unfolded state. The second graph (520) of FIG. 5C represents the efficiency of the second antenna in the unfolded state. In the unfolded state, since the first conductive portion (411) and the second side (321) do not overlap, the performance of the first antenna may be the highest. Since the efficiency of the first antenna of the foldable electronic device according to an embodiment (e.g., the foldable electronic device (300) of FIG. 5A) and the efficiency of the first antenna of the electronic device according to a comparative example (e.g., the foldable electronic device (500) according to the comparative example of FIG. 5A) may be substantially the same, the first graph (510) may be referred to as the efficiency of the first antenna of the foldable electronic device (300) according to an embodiment and the efficiency of the first antenna of the electronic device (500) according to the comparative example. Since the efficiency of the second antenna of the foldable electronic device (300) according to one embodiment and the efficiency of the second antenna of the electronic device (500) according to the comparative example may be substantially the same, the second graph (520) may be referred to as the efficiency of the second antenna of the foldable electronic device (300) according to one embodiment and the efficiency of the second antenna of the electronic device (500) according to the comparative example.

[0161] The third graph (530) of FIG. 5c shows the efficiency of the first antenna in the folded state of the foldable electronic device (300) according to one embodiment. The fourth graph (540) of FIG. 5c shows the efficiency of the first antenna in the folded state of the electronic device (500) according to a comparative example.

[0162] Comparing the third graph (530) and the fourth graph (540), in the first frequency band (e.g., about 1 GHz or less), the third graph (530) may have higher efficiency than the fourth graph (540). For example, in the frequency band between about 0.9 GHz and about 1 GHz, the third graph (530) may have efficiency that is about 3.5 dB to 4 dB higher than the fourth graph (540). Referring to the third graph (530) and the fourth graph (540), the efficiency of the first antenna of the foldable electronic device (300) according to one embodiment may be higher than the efficiency of the first antenna of the foldable electronic device (500) according to the comparative example. The foldable electronic device (300) according to one embodiment may provide superior communication performance for the first signal on the first frequency band than the foldable electronic device (500) according to the comparative example.

[0163] The fifth graph (550) of FIG. 5c shows the efficiency of the second antenna in the folded state of the foldable electronic device (300) according to one embodiment. The sixth graph (560) of FIG. 5c shows the efficiency of the second antenna in the folded state of the foldable electronic device (500) according to a comparative example.

[0164] Comparing the fifth graph (550) and the sixth graph (560), in the second frequency band (e.g., about 1.1 GHz or higher), the fifth graph (550) may have higher efficiency than the sixth graph (560). For example, in the frequency band between about 1.1 GHz and about 1.2 GHz, the fifth graph (550) may have efficiency that is about 3 dB to 3.5 dB higher than the sixth graph (560). Referring to the fifth graph (550) and the sixth graph (560), the efficiency of the second antenna of the foldable electronic device (300) according to one embodiment may be higher than the efficiency of the second antenna of the electronic device (500) according to the comparative example. The foldable electronic device (300) according to one embodiment may provide superior communication performance for a second signal on the second frequency band than the electronic device (500) according to the comparative example.

[0165] As described above, the foldable electronic device (300) according to one embodiment can provide relatively excellent communication performance by reducing the effect of the second side (321) blocking the radiation of signals and interference with the signals, and providing a path through which the signals can be radiated, through the third non-conductive portion (423) included in the second side (321) in the folded state. The first antenna can use at least a part of the first conductive portion (411) as an antenna radiator. The second antenna can use at least a part of the third conductive portion (413) as an antenna radiator. In order to increase the efficiency of the first antenna and the efficiency of the second antenna, the foldable electronic device (300) according to one embodiment may include, in a folded state of the foldable electronic device (300), a second non-conductive portion (422) adjacent to each of the first non-conductive portion (421) and the third non-conductive portion (423), and a fifth non-conductive portion (425) adjacent to each of the fourth non-conductive portion (424) and the sixth non-conductive portion (426). As described above, the first end of the second non-conductive portion (422) (e.g., the first end (422a) of FIG. 3c) can overlap the first end of the first non-conductive portion (421) (e.g., the first end (421a) of FIG. 3c), and the second end of the second non-conductive portion (422) (e.g., the second end (422b) of FIG. 3c) can overlap the first end of the third non-conductive portion (423) (e.g., the first end (423a) of FIG. 3c). The first end of the fifth non-conductive portion (425) (e.g., the first end (425a) of FIG. 3d) can overlap the first end of the fourth non-conductive portion (424) (e.g., the first end (424a) of FIG. 3d) and the fifth non-conductive portion (425) The second end of the portion (425) (e.g., the second end (425b) of FIG. 3d) may overlap the first end of the sixth non-conductive portion (426) (e.g., the first end (426a) of FIG. 3d).As the second non-conductive portion (422) and the fifth non-conductive portion (425) help to form a strong electric field, the efficiency of the first antenna and the efficiency of the second antenna can be increased.

[0166] Hereinafter, various embodiments of a foldable housing (301) of a foldable electronic device (300) according to one embodiment are described. As described above, the foldable housing (301) of the foldable electronic device (300) according to one embodiment may have a structure described with reference to FIGS. 3c and 3d.

[0167] FIGS. 6A and 6B illustrate a foldable electronic device according to one embodiment including non-conductive portions having different widths.

[0168] Referring to FIG. 6A, the first width of the first non-conductive portion (421) may be narrower than the second width of the second non-conductive portion (422). The third width of the third non-conductive portion (423) may be narrower than the second width of the second non-conductive portion (422). According to one embodiment, in a folded state of the foldable electronic device (300), the second non-conductive portion (422) may have a relatively wide width such that the first end (422a) of the second non-conductive portion (422) overlaps the first end (421a) of the first non-conductive portion (421), and the second end (422b) of the second non-conductive portion (422) overlaps the first end (423a) of the third non-conductive portion (423).

[0169] In one embodiment, the width of the second non-conductive portion (422) may not be constant. For example, the first end (422a) of the second non-conductive portion (422) that overlaps the first end (421a) of the first non-conductive portion (421) may be narrower than the second end (422b) of the second non-conductive portion (422) that overlaps the first end (423a) of the third non-conductive portion (423). However, the present invention is not limited thereto. Referring to FIG. 6b, the first end (422a) of the second non-conductive portion (422) that overlaps the first end (421a) of the first non-conductive portion (421) may be wider than the second end (422b) of the second non-conductive portion (422) that overlaps the first end (423a) of the third non-conductive portion (423).

[0170] Referring again to FIG. 6A, the foldable electronic device (300) according to one embodiment may further include a fourth non-conductive portion (424), a fifth non-conductive portion (425), and a sixth non-conductive portion (426).

[0171] Referring to FIG. 6A, the fourth width of the fourth non-conductive portion (424) may be narrower than the fifth width of the fifth non-conductive portion (425). The sixth width of the sixth non-conductive portion (426) may be narrower than the fifth width of the fifth non-conductive portion (425). According to one embodiment, in a folded state of the foldable electronic device (300), the first end (425a) of the fifth non-conductive portion (425) overlaps the first end (424a) of the fourth non-conductive portion (424), and the second end (425b) of the fifth non-conductive portion (425) overlaps the first end (426a) of the sixth non-conductive portion (426), so that the fifth non-conductive portion (425) may have a relatively wide width.

[0172] In one embodiment, the width of the fifth non-conductive portion (425) may not be constant. For example, the first end (425a) of the fifth non-conductive portion (425) that overlaps the first end (424a) of the fourth non-conductive portion (424) may be narrower than the second end (425b) of the fifth non-conductive portion (425) that overlaps the first end (426a) of the sixth non-conductive portion (426). However, the present invention is not limited thereto. Referring to FIG. 6b, the first end (425a) of the fifth non-conductive portion (425) that overlaps the first end (424a) of the fourth non-conductive portion (424) may be wider than the second end (425b) of the fifth non-conductive portion (425) that overlaps the first end (426a) of the sixth non-conductive portion (426).

[0173] FIGS. 7A and 7B illustrate a foldable electronic device according to one embodiment including portions having different extension directions.

[0174] Referring to FIG. 7a, in a folded state of the foldable electronic device (300), the second non-conductive portion (422) may include portions having different extension directions such that the first end (422a) of the second non-conductive portion (422) overlaps with the first end (421a) of the first non-conductive portion (421), and the second end (422b) of the second non-conductive portion (422) overlaps with the first end (423a) of the third non-conductive portion (423).

[0175] According to one embodiment, the second non-conductive portion (422) may include a plurality of portions extending in different directions between the first end (422a) and the second end (422b).

[0176] According to one embodiment, the second non-conductive portion (422) may include a first portion (701), a second portion (702), and a third portion (703). The first portion (701) may be a portion extending straight in the -z direction from the first end (422a). The second portion (702) may be a portion extending straight in the +z direction from the second end (422b). The first portion (701) and the second portion (702) may not be on the same line but may be misaligned. The third portion (703) may be a portion extending so as to connect an end of the first portion (701) and an end of the second portion (702). For example, the extension direction of the third portion (703) may be a direction perpendicular to the extension direction of the first portion (701) and the extension direction of the second portion (702) (e.g., the x-axis direction). However, this is not limited thereto. According to one embodiment, the second non-conductive portion (422) may include a plurality of portions having different extension directions, thereby satisfying the structure described with reference to FIGS. 3b and 3c. In a folded state of the foldable electronic device (300), when viewed in a direction perpendicular to the rear surface of the foldable housing (301) (e.g., +y direction), the first end (421a) of the first non-conductive portion (421) and the first end (422a) of the second non-conductive portion (422) may overlap each other, and the second end (422b) of the second non-conductive portion (422) and the first end (423a) of the third non-conductive portion (423) may overlap each other. In one embodiment, in a folded state of the foldable electronic device (300), the second end (421b) of the first non-conductive portion (421) and the second end (422b) of the second non-conductive portion (422) may not overlap each other when viewed in a direction perpendicular to the rear surface of the foldable housing (301) (e.g., +y direction), and the second end (422b) of the second non-conductive portion (422) and the second end (423b) of the third non-conductive portion (423) may not overlap each other.

[0177] A foldable electronic device (300) according to one embodiment may further include a fourth non-conductive portion (424), a fifth non-conductive portion (425), and a sixth non-conductive portion (426). The fourth non-conductive portion (424), the fifth non-conductive portion (425), and the sixth non-conductive portion (426) may be symmetrical with respect to the first non-conductive portion (421), the second non-conductive portion (422), and the third non-conductive portion (423), respectively.

[0178] According to one embodiment, the fifth non-conductive portion (425) may include a fourth portion (704), a fifth portion (705), and a sixth portion (706). The fourth portion (704) may be a portion extending straight in the -z direction from the first end (422a). The fifth portion (705) may be a portion extending straight in the +z direction from the second end (422b). The fourth portion (704) and the fifth portion (705) may not be on the same line but may be misaligned. The sixth portion (706) may be a portion extending so as to connect an end of the fourth portion (704) and an end of the fifth portion (705). For example, the extension direction of the sixth portion (706) may be a direction perpendicular to the extension direction of the fourth portion (704) and the extension direction of the fifth portion (705) (e.g., the x-axis direction). However, this is not limited thereto. According to one embodiment, the fifth non-conductive portion (425) may include a plurality of portions having different extension directions, thereby satisfying the structure described with reference to FIGS. 3b and 3c. In a folded state of the foldable electronic device (300), when viewed in a direction perpendicular to the rear surface of the foldable housing (301) (e.g., +y direction), the first end (424a) of the fourth non-conductive portion (424) and the first end (425a) of the fifth non-conductive portion (425) may overlap each other, and the second end (425b) of the fifth non-conductive portion (425) and the first end (426a) of the sixth non-conductive portion (426) may overlap each other. In one embodiment, in a folded state of the foldable electronic device (300), the second end (424a) of the fourth non-conductive portion (424) and the second end (425b) of the fifth non-conductive portion (425) may not overlap each other when viewed in a direction perpendicular to the rear surface of the foldable housing (301) (e.g., +y direction), and the second end (425b) of the fifth non-conductive portion (425) and the second end (426b) of the sixth non-conductive portion (426) may not overlap each other.

[0179] Referring to FIG. 7b, an example of a structure in which the fourth non-conductive portion (424), the fifth non-conductive portion (425), and the sixth non-conductive portion (426) are not symmetrical with respect to the first non-conductive portion (421), the second non-conductive portion (422), and the third non-conductive portion (423) is illustrated.

[0180] Referring to FIG. 7B, the first non-conductive portion (421), the second non-conductive portion (422), and the third non-conductive portion (423) may have the structure illustrated in FIG. 7A. The fourth non-conductive portion (424), the fifth non-conductive portion (425), and the sixth non-conductive portion (426) may overlap as a whole when viewed in a direction perpendicular to the rear surface of the foldable housing (301) (e.g., +y direction).

[0181] Referring to FIG. 7b, even if the fourth non-conductive portion (424), the fifth non-conductive portion (425), and the sixth non-conductive portion (426) are not symmetrical with the first non-conductive portion (421), the second non-conductive portion (422), and the third non-conductive portion (423), a segmented structure for improving the communication performance of the foldable electronic device (300) can be satisfied. For example, in the embodiment illustrated in FIG. 7b, in the folded state of the foldable electronic device (300), even if the fourth non-conductive portion (424), the fifth non-conductive portion (425), and the sixth non-conductive portion (426) are entirely overlapped, since the first non-conductive portion (421), the second non-conductive portion (422), and the third non-conductive portion (423) satisfy the structure described in FIGS. 3b and 3c, the foldable electronic device (300) can have the effect of improving communication performance described with reference to FIGS. 3a and 3b.

[0182] Figure 8 illustrates an example of a second non-conductive portion including portions having different extension directions.

[0183] Referring to FIG. 8, the second non-conductive portion (422) may include portions extending in different directions. In the structure described above with reference to FIG. 7A, a third portion (e.g., the third portion (703) of FIG. 7A) and a sixth portion (e.g., the sixth portion (706) of FIG. 7A) may be connected to form a second non-conductive portion (422) having the structure illustrated in FIG. 8. According to one embodiment, the second non-conductive portion (422) may include a first portion (801), a second portion (802), a third portion (803), a fourth portion (804), and a fifth portion (805).

[0184] According to one embodiment, the first portion (801) may be a portion extending in the -z direction from a first end (422a) that overlaps with a first end (421a) of the first non-conductive portion (421). The second portion (802) may be a portion that is displaced from the first portion (801) and extends in the +z direction from the second end (422b). The third portion (803) may cross the second side surface (321) in a longitudinal direction of the second side surface (321) (e.g., in the x-axis direction). The fourth portion (804) may be a portion extending in the -z direction from a first end (425a) that overlaps with a first end (424a) of the fourth non-conductive portion (424). The fifth portion (805) may be a portion that is misaligned with the fourth portion (804) and extends in the +z direction from the second end (425b). The third portion (803) may be a portion that is formed along the longitudinal direction (e.g., x-axis direction) of the second side (321), thereby being connected to an end of the first portion (801), an end of the second portion (802), an end of the fourth portion (804), and an end of the fifth portion (805). For example, the third portion (803) may extend from one end of the second side (321) to the other end of the second side (321).

[0185] FIG. 9 illustrates a foldable electronic device according to one embodiment.

[0186] Referring to FIG. 9, the shape of the second non-conductive portion (422) may be different from the shape of the fifth non-conductive portion (425). According to one embodiment, the fifth non-conductive portion (425) may extend parallel to a direction (e.g., -z direction) from the first housing part (310) toward the third housing part (330) in a folded state of the foldable electronic device (300). The second non-conductive portion (422) may extend so as to have an inclination with respect to the direction.

[0187] According to one embodiment, the fourth non-conductive portion (424) and the sixth non-conductive portion (426) may extend parallel to the direction. When the foldable electronic device (300) is in a folded state, when viewed in a direction perpendicular to the rear surface of the foldable housing (301), the fourth non-conductive portion (424), the fifth non-conductive portion (425), and the sixth non-conductive portion (426) may overlap as a whole.

[0188] According to one embodiment, even if the fourth non-conductive portion (424), the fifth non-conductive portion (425), and the sixth non-conductive portion (426) do not satisfy the structure illustrated in FIGS. 3B and 3C, if the first non-conductive portion (421), the second non-conductive portion (422), and the third non-conductive portion (423) satisfy the structure, the segmented structure for improving the communication performance of the foldable electronic device (300) can be satisfied. As illustrated in FIG. 9, in the folded state of the foldable electronic device (300), even if the fourth non-conductive portion (424), the fifth non-conductive portion (425), and the sixth non-conductive portion (426) entirely overlap each other, since the first non-conductive portion (421), the second non-conductive portion (422), and the third non-conductive portion (423) satisfy the structure described in FIGS. 3b and 3c, the foldable electronic device (300) can have the effect of improving communication performance described with reference to FIGS. 3a and 3b.

[0189] FIGS. 10A, 10B, 10C, and 10D illustrate examples of foldable housings that each include only one non-conductive portion within each side.

[0190] According to one embodiment, the foldable electronic device (300) may include a first non-conductive portion (421), a second non-conductive portion (422), and a third non-conductive portion (423). For example, as illustrated in FIGS. 10A, 10B, 10C, and 10D , the fourth non-conductive portion (424), the fifth non-conductive portion (425), and the sixth non-conductive portion (426) may be omitted. Although not illustrated, the foldable electronic device (300) may also include only the fourth non-conductive portion (e.g., the fourth non-conductive portion (424) of FIG. 3D ), the fifth non-conductive portion (e.g., the fifth non-conductive portion (425) of FIG. 3D ), and the sixth non-conductive portion (e.g., the sixth non-conductive portion (426) of FIG. 3D ).

[0191] According to one embodiment, the structure described with reference to FIGS. 3b and 3c can be substantially equally applied even when it includes only the first non-conductive portion (421), the second non-conductive portion (422), and the third non-conductive portion (423) (or the fourth non-conductive portion (424), the fifth non-conductive portion (425), and the sixth non-conductive portion (426)).

[0192] Referring to FIG. 10A, a first end (421a) of a first non-conductive portion (421) and a first end (422a) of a second non-conductive portion (422) may be arranged to overlap each other when viewed in a direction perpendicular to the rear surface of the foldable housing (301) (e.g., +y direction) when the foldable electronic device (300) is in a folded state. A second end (422b) of a second non-conductive portion (422) and a first end (423a) of a third non-conductive portion (423) may be arranged to overlap each other when viewed in a direction perpendicular to the rear surface of the foldable housing (301) (e.g., +y direction) when the foldable electronic device (300) is in a folded state. In the embodiment illustrated in FIG. 10A, in the folded state of the foldable electronic device (300), the first non-conductive portion (421) and the second non-conductive portion (422) may be arranged such that a second virtual line (V2) extending from the first non-conductive portion (421) is different from a third virtual line (V3) extending from the second non-conductive portion (422). For example, the third virtual line (V3) may be inclined with respect to the second virtual line (V2). In the folded state of the foldable electronic device (300), the second non-conductive portion (422) and the third non-conductive portion (423) may be arranged such that the third virtual line (V3) extending from the second non-conductive portion (422) is different from a fifth virtual line (V5) extending from the third non-conductive portion (423). For example, the third virtual line (V3) may be inclined with respect to the fifth virtual line (V5).

[0193] Referring to FIG. 10b, the second width of the second non-conductive portion (422) may be wider than the first width of the first non-conductive portion (421) and the third width of the third non-conductive portion (423). The width of the first end (422a) of the second non-conductive portion (422) may be formed such that, when viewed in a direction perpendicular to the rear surface of the foldable housing (301) (e.g., +y direction) in a folded state of the foldable electronic device (300), the first end (422a) of the second non-conductive portion (422) overlaps the first end (421a) of the first non-conductive portion (421). The width of the second end (422b) of the second non-conductive portion (422) may be formed such that, when the foldable electronic device (300) is in a folded state and viewed in a direction perpendicular to the rear surface of the foldable housing (301) (e.g., +y direction), the second end (422b) of the second non-conductive portion (422) overlaps the first end (423a) of the third non-conductive portion (423).

[0194] Referring to FIG. 10c, the second non-conductive portion (422) may include portions extending in different directions. For example, the second non-conductive portion (422) may include a first portion (701), a second portion (702), and a third portion (703). The first portion (701) may be a portion extending in the -z direction from the first end (422a). The second portion (702) may be a portion extending in the +z direction from the second end (422b). The first portion (701) and the second portion (702) may not be on the same line and may be misaligned. The third portion (703) may be a portion extending so as to connect an end of the first portion (701) and an end of the second portion (702). For example, the extension direction of the third part (703) may be a direction perpendicular to the extension direction of the first part (701) and the extension direction of the second part (702) (e.g., the x-axis direction).

[0195] Referring to FIG. 10d, the second non-conductive portion (422) may include portions having different extension directions. For example, the second non-conductive portion (422) may include a first portion (801), a second portion (802), and a third portion (803). According to one embodiment, the first portion (801) may be a portion extending in the -z direction from a first end (422a) that overlaps with a first end (421a) of the first non-conductive portion (421). The second portion (802) may be a portion that is displaced from the first portion (801) and extends in the +z direction from the second end (422b). The third portion (803) may cross the second side surface (321) in a longitudinal direction of the second side surface (321) (e.g., in the x-axis direction).

[0196] In addition to the embodiments described with reference to FIGS. 10a, 10b, 10c, and 10d, various embodiments may be possible.

[0197] FIGS. 11a, 11b, and 11c illustrate examples of foldable housings having a structure in which a first length corresponds to a second length.

[0198] According to one embodiment, a first length (L1) of a first conductive portion (411) forming at least a portion of a first antenna (e.g., the first antenna (210) of FIG. 2) may correspond to a second length (L2) of a third conductive portion (413) forming at least a portion of a second antenna (e.g., the second antenna (220) of FIG. 2). For example, the first length (L1) may be substantially the same as the second length (L2). For example, when the difference between the first frequency band and the second frequency band is small, the first length (L1) and the second length (L2) may be substantially the same. Alternatively, the first frequency band and the second frequency band may be the same. For example, the foldable electronic device (300) may provide reception diversity by using the first antenna and the second antenna. For example, the first antenna may operate as a primary antenna, and the second antenna may operate as a diversity antenna. However, the above description is only exemplary and is not limiting.

[0199] According to one embodiment, the first conductive portion (411) may be disposed between the first non-conductive portion (421) and the fourth non-conductive portion (424). The first non-conductive portion (421) may contact one end (411a) of the first conductive portion (411), and the fourth non-conductive portion (424) may contact the other end (411b) of the first conductive portion (411). A first length (L1) of the first conductive portion (411) may correspond to a distance between the first non-conductive portion (421) and the fourth non-conductive portion (424). The third conductive portion (413) may be disposed between the third non-conductive portion (423) and the sixth non-conductive portion (426). The third non-conductive portion (423) may be in contact with one end (413a) of the third conductive portion (413), and the sixth non-conductive portion (426) may be in contact with the other end (413b) of the third conductive portion (413). The second length (L2) of the third conductive portion (413) may correspond to the distance between the third non-conductive portion (423) and the sixth non-conductive portion (426).

[0200] According to one embodiment, even when the first length (L1) corresponds to the second length (L2), the foldable housing (301) can satisfy the structure described with reference to FIGS. 3B and 3C. For example, even when the first length (L1) and the second length (L2) are the same, in the folded state of the foldable electronic device (300), the first end (421a) of the first non-conductive portion (421) facing the second housing part (320) and the first end (422a) of the second non-conductive portion (422) facing the first housing part (310) can be arranged to overlap each other when viewed in a direction perpendicular to the rear surface of the foldable housing (301) (e.g., +y direction). For example, even when the first length (L1) and the second length (L2) are the same, in the folded state of the foldable electronic device (300), the second end (421b) of the first non-conductive portion (421) and the second end (422b) of the second non-conductive portion (422) may be arranged so as not to overlap each other when viewed in the direction perpendicular to the rear surface of the foldable housing (301). Even when the first length (L1) and the second length (L2) are the same, the second end (422b) of the second non-conductive portion (422) and the first end (423a) of the third non-conductive portion (423) may be arranged so as to overlap each other when viewed in the direction perpendicular to the rear surface of the foldable housing (301). For example, even when the first length (L1) and the second length (L2) are the same, in the folded state of the foldable electronic device (300), the first end (422a) of the second non-conductive portion (422) and the second end (423b) of the third non-conductive portion (423) may be arranged so as not to overlap each other when viewed in the direction perpendicular to the rear surface of the foldable housing (301).

[0201] The above structure can be applied substantially equally to the fourth non-conductive portion (424), the fifth non-conductive portion (425), and the sixth non-conductive portion (426). According to one embodiment, even when the first length (L1) and the second length (L2) are substantially the same or similar, in the folded state of the foldable electronic device (300), the first end (424a) of the fourth non-conductive portion (424) facing the second housing part (320) and the first end (425a) of the fifth non-conductive portion (425) facing the first housing part (310) can be arranged to overlap each other when viewed in a direction perpendicular to the rear surface of the foldable housing (301) (e.g., +y direction). For example, even when the first length (L1) and the second length (L2) are the same, in the folded state of the foldable electronic device (300), the second end (424b) of the fourth non-conductive portion (424) and the second end (425b) of the fifth non-conductive portion (425) may be arranged so as not to overlap each other when viewed in the direction perpendicular to the rear surface of the foldable housing (301). Even when the first length (L1) and the second length (L2) are the same, in the folded state of the foldable electronic device (300), the second end (425b) of the fifth non-conductive portion (425) and the first end (426a) of the sixth non-conductive portion (426) may be arranged so as to overlap each other when viewed in the direction perpendicular to the rear surface of the foldable housing (301). For example, even when the first length (L1) and the second length (L2) are the same, in the folded state of the foldable electronic device (300), the first end (425a) of the fifth non-conductive portion (425) and the second end (426b) of the sixth non-conductive portion (426) may be arranged so as not to overlap each other when viewed in the direction perpendicular to the rear surface of the foldable housing (301).

[0202] Referring to FIG. 11A, the extension direction of the first non-conductive portion (421) and the extension direction of the third non-conductive portion (423) may be substantially the same, and the second non-conductive portion (422) may be inclined with respect to the extension direction of the first non-conductive portion (421) and the extension direction of the third non-conductive portion (423). The extension direction of the fourth non-conductive portion (424) and the extension direction of the sixth non-conductive portion (426) may be substantially the same, and the fifth non-conductive portion (425) may be inclined with respect to the extension direction of the fourth non-conductive portion (424) and the extension direction of the sixth non-conductive portion (426).

[0203] According to one embodiment, even when the first length (L1) and the second length (L2) are substantially the same, when the first antenna and / or the second antenna operate, an electric field may be strongly formed in a region adjacent to the non-conductive portion. By the second non-conductive portion (422) and the fifth non-conductive portion (425), the efficiency of the first antenna and / or the efficiency of the second antenna may be improved.

[0204] Referring to FIG. 11B, at least one second non-conductive portion (422) may include portions having different extension directions. The embodiment illustrated in FIG. 11B may be substantially the same as the embodiment illustrated in FIG. 7A, except that the first length (L1) of the first conductive portion (411) and the second length (L2) of the third conductive portion (413) are substantially the same structure. In one embodiment, the efficiency of the first antenna and / or the efficiency of the second antenna may be improved by the second non-conductive portion (422) and the fifth non-conductive portion (425).

[0205] Referring to FIG. 11c, at least one second non-conductive portion (422) may include portions having different extension directions. The embodiment illustrated in FIG. 11b may be substantially the same as the embodiment illustrated in FIG. 8, except that the first length (L1) of the first conductive portion (411) and the second length (L2) of the third conductive portion (413) are substantially the same structure. In one embodiment, the efficiency of the first antenna and / or the efficiency of the second antenna may be improved by the second non-conductive portion (422) and the fifth non-conductive portion (425).

[0206] Fig. 12a is a graph showing the efficiency of the first antenna according to the permittivity of the second non-conductive portion. Fig. 12b is a graph showing the efficiency of the second antenna according to the permittivity of the third non-conductive portion.

[0207] In one embodiment, the second permittivity of the second material forming the second non-conductive portion (422) may be higher than the first permittivity of the first material forming the first non-conductive portion (421). The second permittivity of the second material forming the second non-conductive portion (422) may be higher than the third permittivity of the third material forming the third non-conductive portion (423). When the second permittivity is higher than the first permittivity and the third permittivity, the efficiency of the first antenna and the efficiency of the second antenna may be improved.

[0208] According to one embodiment, the foldable electronic device (300) may further include a fourth non-conductive portion (424), a fifth non-conductive portion (425), and a sixth non-conductive portion (426). In this case, the fifth permittivity of the fifth material forming the fifth non-conductive portion (425) may be higher than the fourth permittivity of the fourth material forming the fourth non-conductive portion (424). The fifth permittivity of the fifth material forming the fifth non-conductive portion (425) may be higher than the sixth permittivity of the sixth material forming the sixth non-conductive portion (426). When the fifth permittivity is higher than the fourth permittivity and the sixth permittivity, the efficiency of the first antenna and the efficiency of the second antenna may be improved.

[0209] The first graph (1201) of Fig. 12a shows the efficiency of the first antenna when the second permittivity is approximately 2.7. The second graph (1202) of Fig. 12a shows the efficiency of the first antenna when the second permittivity is approximately 6.5. Comparing the first graph (1201) and the second graph (1202), the second graph (1202) may show higher efficiency than the first graph (1201) for signals in the first frequency band (e.g., approximately 1 GHz or less).

[0210] The third graph (1203) of Fig. 12b shows the efficiency of the second antenna when the second permittivity is approximately 2.7. The fourth graph (1204) of Fig. 12b shows the efficiency of the first antenna when the second permittivity is approximately 6.5. Comparing the third graph (1203) and the fourth graph (1204), the fourth graph (1204) may show higher efficiency than the third graph (1203) for signals in the second frequency band (e.g., approximately 1.1 GHz or higher).

[0211] According to one embodiment, when the permittivity of the second non-conductive portion (422) and / or the fifth non-conductive portion (425) is high, the intensity of the electric field may be strengthened when the first antenna and / or the second antenna operates. The foldable electronic device (300) according to one embodiment may provide improved communication performance by including the second non-conductive portion (422) and / or the fifth non-conductive portion (425) formed of a material having a relatively high permittivity.

[0212] Fig. 13a is a diagram showing the electromagnetic wave absorption rate of an electronic device according to a comparative example. Fig. 13b is a diagram showing the electromagnetic wave absorption rate of an electronic device according to one embodiment.

[0213] Referring to FIG. 13A, the electronic device (1300) according to the comparative example may be referred to as a case where the dielectric constant of the material forming the second non-conductive portion (1301) and / or the fifth non-conductive portion (1302) is about 2.7. Referring to FIG. 13B, the foldable electronic device (300) according to one embodiment may be referred to as a case where the third dielectric constant of the second non-conductive portion (422) and / or the fifth non-conductive portion (425) is about 6.5. For example, when the first antenna operates, the specific absorption rate (SAR) by the foldable electronic device (300) according to one embodiment may be lower than the SAR by the electronic device (1300) according to the comparative example. For example, while the first antenna transmits and / or receives a signal in a frequency band of about 1 GHz, the 10g reference SAR may be about 4.09 W / kg for the foldable electronic device (300) according to one embodiment, and may be about 4.36 W / kg for the electronic device according to the comparative example. According to one embodiment, when the third permittivity increases from about 2.7 to about 6.5, the 10g reference SAR may be about 0.27 W / kg lower. The foldable electronic device (300) according to one embodiment may lower the SAR by including at least one third non-conductive portion (450) formed of a material having a relatively high permittivity.

[0214] The foldable electronic device described above (e.g., the foldable electronic device (300) of FIG. 3A) has been described as a device having a structure in which the second housing part (320) and the third housing part (330) are folded in different directions with respect to the first housing part (310), but the structure of the electronic device (1401) is not limited thereto.

[0215] FIG. 14 illustrates a process in which an electronic device according to one embodiment changes from an unfolded state to a folded state.

[0216] According to one embodiment, the electronic device (1401) may have a structure in which the first housing part (1410) and the second housing part (1420) are folded in the same direction relative to the third housing part (1430). Except for the difference in the folding method, the electronic device (1401) described below may be substantially the same as the electronic device described above (e.g., the foldable electronic device (300) of FIG. 3A).

[0217] Referring to FIG. 14, an electronic device (1401) according to one embodiment may include a plurality of housing parts that are rotatably coupled. For example, the housing may include a first housing part (1410), a second housing part (1420), and a third housing part (1430) that are rotatably coupled to each other.

[0218] In one embodiment, the first housing part (1410) can be rotatably coupled to one side of the second housing part (1420). The third housing part (1430) can be rotatably coupled to the other side of the second housing part (1420). For example, the hinge assemblies can include a first hinge assembly (1441) that rotatably couples the third housing part (1430) to the second housing part (1420) and a second hinge assembly (1442) that rotatably couples the first housing part (1410) to the second housing part (1420).

[0219] An electronic device (1401) according to one embodiment may include a flexible display (1450). The flexible display (1450) may include a first bendable portion (1451) that can be folded by rotation of a second housing part (1420) and rotation of a third housing part (1430), and a second bendable portion (1452) that can be folded by rotation of the first housing part (1410) and rotation of the third housing part (1430).

[0220] The first state (1400a) of FIG. 14 may be referred to as an unfolded state of the electronic device (1401). The first state (1400a) may represent a fully unfolded state in which the first housing part (1410), the second housing part (1420), and the third housing part (1430) are fully unfolded. Within the unfolded state, the first housing part (1410), the second housing part (1420), and the third housing part (1430) may be arranged on substantially the same plane. Within the first state (1400a), the first bendable part (1451) and the second bendable part (1452) may be substantially flat. Within the first state (1400a), the third housing part (1430) can be positioned between the first housing part (1410) and the second housing part (1420).

[0221] The second state (1400b) of FIG. 14 may represent a state in which the third housing part (1430) is folded relative to the third housing part (1420). Within the first state (1400a), as the third housing part (1430) rotates relative to the second housing part (1420), the electronic device (1401) may change from the first state (1400a) to the second state (1400b). For example, the third housing part (1430) may be rotated in a first direction (e.g., counterclockwise) relative to the second housing part (1420) by the first hinge assembly (1441). When the third housing part (1430) is rotated about 180 degrees, a second state (1400b) can be provided in which the third housing part (1430) is placed on the second housing part (1420). Within the second state (1400b), the first bendable portion (1451) can be bent.

[0222] The third state (1400c) of FIG. 14 may be referred to as a folded state of the electronic device (1401). The third state (1400c) may represent a fully folded state in which the first housing part (1410), the second housing part (1420), and the third housing part (1430) are folded. In the folded state, when the electronic device (1401) is viewed from above, the first housing part (1410), the second housing part (1420), and the third housing part (1430) may overlap each other. In the second state (1400b), as the first housing part (1410) is rotated relative to the second housing part (1420), the electronic device (1401) may change from the second state (1400b) to the third state (1400c). For example, the first housing part (1410) can be rotated in a first direction (e.g., counterclockwise) relative to the second housing part (1420) by the second hinge assembly (1442). When the first housing part (1410) is rotated about 180 degrees, a third state (1400c) can be provided in which the first housing part (1410) is positioned below the second housing part (1420). Within the third state (1400c), the first bendable part (1451) and the second bendable part (1452) can be bent. The cover display (1460) can be placed on the second housing part (1410). In the third state (1400c), the second housing part (1420) can be placed between the first housing part (1410) and the third housing part (1430).

[0223] Although the aforementioned foldable electronic devices (300, 1400) have been described as including three housing parts, embodiments of the present disclosure are not limited thereto. As described below, the aforementioned structure may be substantially identically or similarly applied to a foldable electronic device (e.g., the foldable electronic device (1500) of FIG. 15A) including two housing parts.

[0224] FIGS. 15A, 15B, and 15C illustrate foldable electronic devices according to various embodiments.

[0225] Referring to FIG. 15A, a foldable electronic device (1500) according to one embodiment may include a foldable housing (1501) including a first housing part (310) and a second housing part (320).

Except for the omission of the second hinge assembly (e.g., the second hinge assembly (342) of FIG. 3B) and the third housing part (e.g., the third housing part (330) of FIG. 3B), the foldable electronic device (1500) according to one embodiment may be substantially the same as the foldable electronic device described above (e.g., the foldable electronic device (300) of FIG. 3A or the foldable electronic device (1400) of FIG. 14). Duplicate descriptions may be omitted or briefly described.

[0226] According to one embodiment, a first conductive portion (411) and a first non-conductive portion (421) may be included within a first side (311) of a first housing part (310). A second conductive portion (412) and a second non-conductive portion (422) may be included within a second side (321) of a second housing part (320).
