According to one embodiment, the electronic device (101) may omit at least one of the components or additionally include other components. The flexible display (130) may be alternatively referred to as a foldable display in that it can be partially folded as described below.

[0023] In one embodiment, the first housing part (110) may define a portion of an outer surface of the electronic device (101). The first housing part (110) may define a first side surface (111), a second side surface (112) spaced apart from and opposite the first side surface (111), and a first side surface of a first side wall (113) surrounding at least a portion of the first side surface (111) and the second side surface (112). In one embodiment, the first housing part (110) may provide a space defined by the first side surface (111), the second side surface (112), and the first side surface as a space for arranging components of the electronic device (101).

[0024] In one embodiment, the second side wall (123) may be pivotally connected to the first side wall (113) via a hinge structure (160) disposed on a hinge cover (165). The hinge structure (160) may include a hinge module and hinge plates (166, 167).

[0025] In one embodiment, the second housing part (120) may include a third face (121), a fourth face (122) facing and spaced from the third face (121), and a second side wall (123) surrounding at least a portion of the third face (121) and the fourth face (122). The second housing part (120) may provide a space defined by the third face (121), the fourth face (122), and the second side of the second side wall (123) as a space for arranging components of the electronic device (101).

[0026] In one embodiment, the flexible display (130) may include a window exposed to the outside. The window may protect the surface of the flexible display (130) and may be formed of a transparent material to transmit visual information provided from the flexible display (130) to the outside. The window may include a glass material such as ultra-thin glass (UTG) or a polymer material such as polyimide (PI).

[0027] In one embodiment, the flexible display (130) may form at least a portion of a first side (111) of the first housing part (110) (e.g., a front side of the first housing part (110)) and a third side (121) of the second housing part (120) (e.g., a front side of the second housing part (120)). The flexible display (130) may be disposed on the first side (111) of the first housing part (110) and the third side (121) of the second housing part (120) across a hinge structure (160) within a hinge cover (165). The flexible display (130) may be configured to bend within a folded state of the electronic device (101) by the hinge structure (160). The flexible display (130) may include a first display area (131), a second display area (132), and a third display area (133). For example, the flexible display (130) may include a first display area (131) disposed on a first surface (111) of a first housing, a second display area (132) disposed on a third surface (121) of a second housing, and a third display area (133) between the first display area (131) and the second display area (132). The flexible display (130) may be supported by a first bracket (170) of the first housing part (110) and a second bracket (180) of the second housing part (120).

[0028] According to one embodiment, the flexible display (130) may include an opening formed in a portion of the screen display area, or a support member (e.g., a bracket) that supports the flexible display (130) may include a recess or an opening. The electronic device (101) may include at least one camera aligned with the recess or the opening. For example, the first display area (131) may further include at least one camera (136) that can acquire an image from the outside through a portion of the first display area (131). According to one embodiment, at least one camera (136) may be included on the back of the flexible display (130) corresponding to the first display area (131) or the second display area (132) of the flexible display (130). For example, at least one camera (136) may be disposed under the flexible display (130) and may be covered by the flexible display (130). The at least one camera (136) may be an under display camera (UDC) that is covered by the flexible display (130) and is not exposed to the outside. However, the flexible display (130) is not limited thereto, and the flexible display (130) may include an opening that exposes the at least one camera (136) to the outside. In one embodiment, the camera (136) may obtain an image of the external environment and / or external objects through the opening.

[0029] In one embodiment, the fourth side (122) of the second housing part (120) may further include at least one camera (134) and display (135) exposed through a portion of the fourth side (122).

[0030] In one embodiment, the hinge structure (160) may be configured to pivotally connect a first bracket (170) forming a first housing part (110) and a second bracket (180) forming a second housing part (120).

[0031] In one embodiment, the electronic device (101) may be in one of a folded state, an unfolded state, or an intermediate state. The folded state may be a state in which the first surface (111) of the first housing part (110) and the third surface (121) of the second housing part (120) face each other. In the folded state, the direction in which the first surface (111) faces and the direction in which the third surface (121) faces may be opposite to each other. The unfolded state may be a state in which the first surface (111) of the first housing part (110) and the third surface (121) of the second housing part (120) are substantially continuous planes. In the unfolded state, the direction in which the first surface (111) faces and the direction in which the third surface (121) faces may be the same. The intermediate state may be a state between the unfolded state and the folded state. In the intermediate state, the direction in which the first side (111) faces and the direction in which the third side (121) faces may be different.

[0032] In one embodiment, while the electronic device (101) is in a folded state, the hinge cover (165) surrounding the hinge structure (160) may be at least partially exposed between the first housing part (110) and the second housing part (120). In another embodiment, while the electronic device (101) is in an unfolded state, the hinge cover (165) may be covered by the first housing part (110) and the second housing part (120).

[0033] In one embodiment, the electronic device (101) can be folded about a folding axis (137) passing through the hinge cover (165) or the hinge structure (160). For example, the hinge structure (160) within the hinge cover (165) can be positioned between the first housing part (110) and the second housing part (120) of the electronic device (101) to enable the electronic device (101) to be bent, curved, or folded. For example, the first housing part (110) can be connected to the second housing part (120) through the hinge structure (160) positioned within the hinge cover (165) and can be rotated about the folding axis (137).

[0034] In one embodiment, the electronic device (101) can be folded such that the first housing part (110) and the second housing part (120) face each other by rotating about the folding axis (137). In one embodiment, the electronic device (101) can be folded such that the first housing part (110) and the second housing part (120) cover or overlap each other.

[0035] The hinge structure (160) may include a hinge module and hinge plates (166, 167). The hinge module may include a hinge gear (162, 163) that pivotally connects the first housing part (110) and the second housing part (120). Through the hinge gear, the rotation of the first housing part (110) and the rotation of the second housing part (120) may be synchronized with each other.

[0036] The first housing part (110) may include a first bracket (170), and the second housing part (120) may include a second bracket (180). The first bracket (170) may be partially surrounded by the first side wall (113), and the second bracket (180) may be partially surrounded by the second side wall (123). The first bracket (170) may be formed integrally with the first side wall (113), and the second bracket (180) may be formed integrally with the second side wall (123). According to one embodiment, the first bracket (170) may be formed separately from the first side wall (113), and the second bracket (180) may be formed separately from the second side wall (123). The first side wall (113) and the second side wall (123) may be formed of a metallic material, a non-metallic material, or a combination thereof. For example, the first side wall (113) may include a conductive portion (118) and a non-conductive portion (119). The conductive portion (118) may be used as a radiator of the antenna.

[0037] One side of the first bracket (170) can be coupled with the rear plate (190), and the other side of the first bracket (170) can be coupled with the flexible display (130). One side of the second bracket (180) can be coupled with the display (135), and the other side of the second bracket (180) can be coupled with the flexible display (130).

[0038] A printed circuit board (150) and a battery may be placed in the space between the surface formed by the first bracket (170) and the second bracket (180) and the surface formed by the display (135) and the rear plate (190). The printed circuit board (150) may be separated so that it may be placed in each of the first bracket (170) of the first housing part (110) and the second bracket (180) of the second housing part (120). Components for implementing various functions of the electronic device (101) may be placed on the printed circuit board (150).

[0039] Figure 2a is a drawing showing the relationship between the hinge structure and the display. Figure 2b is an exploded perspective view showing the components of the hinge structure. Figure 3 is a cross-sectional view showing the display and the hinge structure in a folded state of the electronic device.

[0040] As the rotator, arm, and / or link perform rotational and linear motion within a narrow space within the hinge structure, the display may sag due to movement of components of the hinge structure in the event of an external impact. For example, a link that is linearly coupled to the arm may slide in an unintended direction relative to the arm due to an external impact. The hinge structure described below can provide a structure that restricts the movement of the link in the event of an external impact.

[0041] Referring to FIGS. 2A, 2B and 3, the hinge structure (160) may include support plates (166, 167), at least one base (201), arms (210), rotators (220), and links (230).

[0042] Each of the arms (210) and the rotators (220) may be rotatably coupled to the base (201) of the hinge structure (160). The base (201) may have one side covered by a hinge cover (165). For example, the hinge cover (165) may be positioned below one side of the base (201) and may extend to the side of the base (201).

[0043] One end of each of the arms (210) may be coupled to a structure (a groove or a protrusion) formed on the base (201). One end of each of the arms (210) may be coupled to the structure of the base (201) and may be rotatable around a first rotational axis located at an overlapping portion of each of the arms (210) and the base (201).

[0044] One end of each of the rotators (220) may be coupled to a structure (a groove or a protrusion) formed on the base (201). One end of each of the rotators (220) may be coupled to the structure of the base (201) and may be rotatable around a second rotational axis located at an overlapping portion of each end of the rotators (220) and the base (201). The first rotational axis and the second rotational axis may not coincide with each other. For example, the first rotational axis may be spaced apart from the second rotational axis.

[0045] The support plates (166, 167) may include a first support plate (166) and a second support plate (167). The first support plate (166) may support a portion of the flexible display (130) disposed on the first housing part (110). The second support plate (167) may support a portion of the flexible display (130) disposed on the second housing part (120). The flexible display (130) may include a portion (130a-1) disposed on the first housing part (110), a portion (130a-2) disposed on the second housing part (120), and a portion (130b) disposed on the hinge structure (160). The portion (130b) of the flexible display (130) may include a first planar portion (130-1), a second planar portion (130-2), and a bendable portion (130-3). In the bendable portion (130-3), at least one layer within the flexible display (130) may include a pattern. The pattern may include an opening, a slit, or a groove parallel to the folding axis. The first planar portion (130-1) of the flexible display (130) may be supported by a first support plate (166). The second planar portion (130-2) of the flexible display (130) may be supported by a second support plate (167).

[0046] The arms (210) may include a first set of arms (210a) connected to a first support plate (166) and a second set of arms (210b) connected to a second support plate (167). The first set of arms (210a) may be connected to the first support plate (166) and the base (201). The first set of arms (210a) may be connected to the first support plate (166) via a first set of links (230a). The second set of arms (210b) may be connected to the second support plate (167) and the base (201). The second set of arms (220a) may be connected to the second support plate (167) via a second set of links (230b). Each link included in the first set of links (230a) may be linearly movably connected to a corresponding arm of the first set of arms (210a). Each link included in the second set of links (230b) may be linearly movably connected to a corresponding arm of the second set of arms (210b). The links may slide to the corresponding arms. Within the present disclosure, the first set of arms (210a) may be referred to as the first arm, and the second set of arms (210b) may be referred to as the second arm.

[0047] The rotators (220) may include a first set of rotators (220a) connected to a first support plate (166) and a second set of rotators (220b) connected to a second support plate (167). The first set of rotators (220a) may be connected to the first support plate (166) and the base (201). The second set of rotators (220b) may be connected to the second support plate (167) and the base (201).

[0048] The arms (210), the rotators (220), the links (230), and the support plates (166, 167) can rotate in conjunction with each other. Since the rotation axis of the arm and the rotation axis of the rotator corresponding to the arm are different from each other, the rotation angles of the arms (210), the rotators (220), the links (230), and the support plates (166, 167) can be different. For example, while the electronic device (100) changes to a folded state, the rotation angles of the first set of arms (210a) and the first set of rotators (230a) can be different. Due to the different rotation angles, the first set of rotators (230a) can slide from the corresponding arm. By the movement of the arms (210), rotators (220), links (230) and support plates (166, 167), in the folded state of the electronic device (100), a portion (130b) of the display (130) can be deformed into a water droplet shape.

[0049] The hinge structure (160) may further include a gear assembly (205). The gear assembly (205) may provide rotational force to the arms (210) and the rotators (220). The gears included in the gear assembly (205) may be connected to at least one of the arms (210) or the rotators (220). As the gears within the gear assembly (205) mesh with each other and rotate, the arms (210) (or the rotators (220)) connected to the gear assembly (205) may move in conjunction with each other. For example, when a first set of arms (210a) rotates in a first rotational direction, a second set of arms (220a) may be coupled by the gear assembly (205) and rotate in a second rotational direction. The rotation angle of the first set of arms (210a) in the first rotation direction may be the same as the rotation angle of the second set of arms (220a) in the second rotation direction.

[0050] The hinge structure (160) may include a center plate (250) disposed on the hinge structure (160) base. The center plate (250) may support the bendable portion (130-3) of the display (130). The center plate (250) may be referred to as a center bar.

[0051] The arms (210) may include stoppers arranged to contact the ends of each of the support plates (166, 167) within the folded state of the electronic device (100). The structure of the stoppers is described below with reference to the drawings.

[0052] Figure 4 shows the arm of the hinge structure.

[0053] Referring to FIG. 4, the arms included in the first set (210a) of arms of the hinge structure (160) and the arms included in the second set (210b) of arms may include a stopper (401), a groove (410a, 410b), and a connecting portion (420a, 420b).

[0054] The arms (210a, 210b) may include a portion configured to limit the movement of the support plates (166, 167). The portion of the arms (210a, 210b) may correspond to the stopper (401). For example, the stopper (401) of the arms (210a, 210b) may prevent and / or reduce the movement of the support plates (166, 167) due to an external impact when the electronic device (100) is in a folded state and an external impact is applied. For example, the ends of each of the support plates (166, 167) may be arranged in contact with or close to a portion of the stopper (401). When the ends of the support plates (166, 167) move toward the stopper (401) due to an external impact, they may come into contact with the stopper (401). The support plates (166, 167) in contact with the stopper (401) can prevent further downward movement. Within the present disclosure, the stopper (401) of the arms (e.g., the first arm and / or the second arm) may be referred to as a stopper portion. For example, the first arm (210a) and the second arm (210b) may each include a stopper.

[0055] The connecting portions (420a, 420b) of the arms (210a, 210b) can be rotatably coupled to the base. The connecting portions (420a, 420b) of the arms (210a, 210b) can further include gear teeth (421a, 421b). The connecting portions (420a, 420b) of the arms (210a, 210b) can protrude from the bodies (400a, 400b) of the arms (210a, 210b) toward the base (201). The connecting portions (420a, 420b) can be rotatably coupled to the grooves of the base (201). The gear teeth formed on the surfaces of the connecting portions (420a, 420b) can engage with the gear teeth of the gear assembly (205) of the hinge structure. Each of the connecting portions (420a, 420b) can be rotated by the rotation of the gear teeth of the gear assembly (205) in which the gear teeth of the connecting portions (420a, 420b) are engaged.

[0056] The grooves (410a, 410b) of the arms (210a, 210b) can be joined by inserting a portion of a link (e.g., a link included in a set of links (230a, 230b) of FIG. 2B). The link, which has a portion inserted into the grooves (410a, 410b), can move linearly along the surface of the arm. Depending on the linear movement of the link, the support plates (166, 167) joined to the link can move linearly. The link or the support plate can reduce the sagging of the display (130) connected to the link or the support plate as the movement of the support plate is limited by the stopper (401).

[0057] Figures 5a and 5b are cross-sectional views illustrating the relationship between the stopper and the support plate of the arm when the electronic device begins to change from a folded state to an unfolded state. Figures 6a and 6b are cross-sectional views illustrating the relationship between the stopper and the support plate of the arm in an intermediate state when the electronic device changes from a folded state to an unfolded state. Figures 7a and 7b are cross-sectional views illustrating the relationship between the stopper and the support plate of the arm in an unfolded state of the electronic device.

[0058] Referring to FIGS. 5A and 5B, the initial relationship between the arms and the support plates as the electronic device (100) changes from a folded state to an unfolded state is illustrated. For example, the angle between each of the support plates (166, 167) and the base (201) or center plate (250) of the hinge structure (160) may be approximately 100 degrees.

[0059] In the folded state of the electronic device (100), the end of each of the support plates (166, 167) can be in contact with the stopper (401) formed on the arms (210a, 210b). For example, the end of the first support plate (166) can be in contact with or placed close to the stopper (401) of the first set of arms (210a). In the folded state of the electronic device (100), the end (566) of the first support plate (166) can face the stopper (401). In the folded state of the electronic device (100), the end (566) of the first support plate (166) can be aligned with the stopper (401). When the electronic device (100) begins to change from a folded state to an unfolded state, the end (566) of the first support plate (166) may be spaced from the stopper (401). When the electronic device (100) begins to change from a folded state to an unfolded state, the end (566) of the first support plate (166) may have a reduced area facing the stopper (401). When the electronic device (100) begins to change from a folded state to an unfolded state, the end (566) of the first support plate (166) may be misaligned with the stopper (401).

[0060] The end (566) of the first support plate (166) is arranged in contact with or adjacent to the stopper (401) when the electronic device (100) is in a folded state, thereby reducing the detachment or movement of the first support plate (166) or the link (230) connected to the first support plate (166) due to external impact.

[0061] Referring to FIGS. 6A and 6B, the relationship between the arm and the support plate is illustrated in an intermediate state (e.g., a partially folded state or a partially unfolded state) when the electronic device (100) changes from a folded state to an unfolded state. For example, the angle between each of the support plates (166, 167) and the base (201) or center plate (250) of the hinge structure (160) may be approximately 135 degrees.

[0062] In the folded state of the electronic device (100), the ends of each of the support plates (166, 167) are in contact with the stoppers (401) formed on the arms (210a, 210b), but in an intermediate state in which the electronic device (100) is deformed, the ends of the support plates (166, 167) may be spaced apart from the stoppers (401). For example, the end (566) of the first support plate (166) may be spaced apart from the stoppers (401) of the first set of arms (210a). In the intermediate state in which the electronic device (100) is deformed, the end (566) of the first support plate (166) may not face the stoppers (401). In the intermediate state of the electronic device (100), the end (566) of the first support plate (166) may be misaligned with the stoppers (401).

[0063] The end (566) of the first support plate (166) and the stopper (401) are spaced apart from each other, so that the first support plate (166) may not interfere with or overlap other components of the hinge structure (160) during deformation of the electronic device (100).

[0064] Referring to FIGS. 7A and 7B, the relationship between the arm and the support plate is illustrated in the unfolded state of the electronic device (100). For example, each of the support plates (166, 167) and the base (201) or center plate (250) of the hinge structure (160) may be substantially parallel. For example, the first support plate (166) and the second support plate (167) may be arranged on substantially the same plane.

[0065] In the unfolded state of the electronic device (100), the ends of the support plates (166, 167) may be spaced apart from the stopper (401) and may face the stopper (250). For example, the end (566) of the first support plate (166) may be spaced apart from the stopper (401) of the first set of arms (210a). In the unfolded state of the electronic device (100), the end (566) of the first support plate (166) may face the center plate (250). In the unfolded state of the electronic device (100), the end (566) of the first support plate (166) may be aligned with the center plate (250). For example, the first support plate (166), the second support plate (167), and the center plate (250) may be positioned substantially in the same plane.

[0066] The first support plate (166), the second support plate (167), and the center plate (250) can support the display (130) while the electronic device (100) is in an unfolded state. The first support plate (166), the second support plate (167), and the center plate (250) can be positioned on substantially the same plane, thereby causing the display (130) to unfold on substantially the same plane.

[0067] The first support plate (166), the second support plate (167), and the center plate (250) are rigid plates, and when the electronic device (100) is in an unfolded state, the user can use the display (130) by providing a substantially flat display (130), thereby improving the usability of the display (130). The first support plate (166), the second support plate (167), and the center plate (250) can supplement the rigidity of the display (130) in the unfolded state, thereby reducing damage to the display (130).

[0068] Figures 8a, 8b, and 8c are drawings showing the structure of a stopper for preventing the support plate from coming off.

[0069] Referring to FIG. 8A, a stopper (810) formed on an arm included in a set of arms (210a, 210b) may include a protrusion (801). The protrusion (801) may protrude from a surface (802) of the stopper (810) facing the display (130) (or a surface facing the support plates (166, 167)). One surface (803) of the protrusion (801) may have a height equal to the protruding distance of the protrusion (801) from the surface (802). The protrusion (801) may extend from a portion of the surface (802) of the stopper (810) facing the display (130). The protrusion (801) may be positioned at a position corresponding to an end of the plate. A portion of the surface (802) of the stopper (810) facing the display (130) may be aligned with the support plate (166, 167).

[0070] A stopper (810) having a step by a protrusion (801) can reduce sagging of the display (130) by contacting the support plates (166, 167) when the ends of the support plates (166, 167) supporting the display (130) are moved downward (e.g., in the -Z-axis direction). The protrusion (801) can face the ends of the support plates (166, 167) within the folded state of the electronic device.

[0071] Referring to FIG. 8B, the support plates (166, 167) may include stoppers (820). The stoppers (820) formed on the support plates (166, 167) may include protrusions (821). The protrusions (821) may protrude from a surface (822) facing the arms. The stoppers (820) having a step due to the protrusions (821) may allow the protrusions of the stoppers (820) to contact the ends of the respective arms included in the sets of arms (210a, 210b) when the support plates (166, 167) move downward. As the stoppers (820) of the support plates (166, 167) contact the ends of the respective arms included in the sets of arms (210a, 210b), sagging of the display (130) may be reduced.

[0072] Referring to FIG. 8C, the support plates (166, 167) may include a protrusion (840). The protrusion (840) may protrude toward the arm. Each arm included in the set of arms (210a, 210b) may include a groove (831). The groove (831) may be configured to receive the protrusion (840). For example, the groove (831) may be dug from the arm of the set of arms (210a, 210b). The groove (831) may be formed at a position corresponding to the protrusion (840) formed on the support plates (166, 167).

[0073] The protrusions (840) and the grooves (831) can be brought into contact with the respective grooves (831) included in the sets of arms (210a, 210b) when the support plates (166, 167) are moved downward. As the protrusions (840) of the support plates (166, 167) come into contact with the respective grooves (831) included in the sets of arms (210a, 210b), the sagging of the display (130) can be reduced.

[0074] According to the above-described embodiment, the electronic device may be a foldable electronic device including a flexible display. When an external impact or a drop impact is applied to the electronic device in a folded state, sagging or deformation of the flexible display can be reduced by the stopper formed in the set of arms (210a, 210b).

[0075] The stopper formed in the set of arms (210a, 210b) can limit the movement of the support plate, thereby limiting the slipping or movement of the link attached to the support plate.

[0076] According to the above-described embodiment, the electronic device can reduce breakage or deformation of the display by providing a hinge structure that is robust against external impact.

[0077] The technical tasks to be achieved in this document are not limited to the technical tasks mentioned above, and other technical tasks not mentioned will be clearly understood by those with ordinary knowledge in the technical field to which this document pertains.

[0078] According to the above-described embodiment, an electronic device (e.g., electronic device (101) of FIG. 2A) may include a housing including a first housing part (e.g., first housing part (110) of FIG. 1A) and a second housing part (e.g., second housing part (120) of FIG. 1A). The electronic device may further include a hinge structure (e.g., hinge structure (160) of FIG. 1C). The hinge structure may rotatably connect the first housing part and the second housing part. The electronic device may include a flexible display (e.g., display (130) of FIG. 1C) disposed on the first housing part and the second housing part and extending across the hinge structure.

[0079] The hinge structure may include a base (e.g., base (201) of FIG. 2B), a support plate (e.g., first support plate (166) or second support plate (167) of FIG. 2B) that supports a portion of the flexible display disposed on the first housing part. The hinge structure may include an arm (e.g., an arm included in a set of arms (210a, 210b) of FIG. 2B) that rotatably connects the base and the support plate.

The electronic device may further include a rotator (e.g., a rotator (220a, 220b) of FIG. 2B) rotatably coupled with respect to the base. For example, the connecting structure may correspond to a first connecting structure.

[0089] According to the above-described embodiment, the links and rotators are connected to the support plate, arm, and base, and can move in conjunction with each other. The hinge structure composed of multiple link sections can provide reverse rotation in some sections, thereby providing a teardrop-shaped deformation portion of the flexible display within the folded state of the electronic device.

[0094] In one embodiment, the second connecting structure may be rotatably coupled to the second rotator.

[0095] According to one embodiment, the stopper can limit the folding portion of the display from sagging downward by contacting an end of the support plate when an impact is applied to the electronic device from the outside within the folded state of the electronic device.

[0096] In one embodiment, the base may further include a set of gears arranged thereon and rotatably connecting the arm.

[0097] The stopper may be configured to limit contact between the foldable portion of the display and the set of gears when an impact is applied to the electronic device from the outside within the folded state of the electronic device.

[0098] According to one embodiment, the hinge structure may further include a center plate disposed between the base and the foldable portion of the flexible display.

[0099] The stopper may be configured to limit movement of the support plate so as to reduce a repulsive force transmitted to the flexible display by the center plate when an impact is applied to the electronic device from the outside within the folded state of the electronic device.

[0100] The above support plate can be attached to the back surface of the flexible display.

[0101] While the electronic device changes from an unfolded state to a folded state, the arm can rotate in a first rotational direction with respect to the base, and the support plate can rotate in a second rotational direction with respect to the arm.

[0102] According to the above-described embodiment, the links and rotators are connected to the support plate, arm, and base, and can move in conjunction with each other.

The communication module (990) may operate independently from the processor (920) (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 (990) may include a wireless communication module (992) (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 (994) (e.g., a local area network (LAN) communication module, or a power line communication module). Any of these communication modules may communicate with an external electronic device (904) via a first network (998) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (999) (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 may 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 (992) may use subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (996) to identify or authenticate the electronic device (901) within a communication network such as the first network (998) or the second network (999).

[0132] The wireless communication module (992) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency communications (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (992) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (992) can support various technologies for securing performance in high-frequency bands, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna.

In one embodiment, the antenna module (997) may include an antenna including a radiator formed of a conductor or a conductive pattern formed on a substrate (e.g., a PCB). In one embodiment, the antenna module (997) may include a plurality of antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication method used in a communication network, such as the first network (998) or the second network (999), may be selected from the plurality of antennas, for example, by the communication module (990). A signal or power may be transmitted or received between the communication module (990) and the external electronic device via the selected at least one antenna. In some embodiments, in addition to the radiator, another component (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as a part of the antenna module (997).
