[0079] The first housing part (210) can be rotatably coupled to the second housing part (220) by the first hinge structure (250). The second housing part (220) and the first housing part (210) can be rotated about the first hinge structure (250). While the first housing part (210) is rotated about the first hinge structure (250), the second housing part (220) can be rotated about the first hinge structure (250). For example, when the second housing part (220) and the first housing part (210) are rotated about the first hinge structure (250), the angular displacement of the second housing part (220) may be substantially the same as the angular displacement of the first housing part (210).
[0080] The third housing part (230) can be rotatably coupled to the second housing part (220) by the second hinge structure (260). The second housing part (220) and the third housing part (230) can be rotated about the second hinge structure (260). While the second housing part (220) is rotated about the second hinge structure (260), the third housing part (230) can be rotated about the second hinge structure (260). For example, when the second housing part (220) and the third housing part (230) are rotated about the second hinge structure (260), the angular displacement (or angular change) of the second housing part (220) may be substantially the same as the angular displacement of the third housing part (230).
[0081] The first hinge structure (250) and the second hinge structure (260) can change the state of the electronic device. The first hinge structure (250) and the second hinge structure (260) can provide (or enable) a first state (200a) of the electronic device (200) (or a first state (200a) of the housing structure (201). The first state (200a) of the electronic device (200) (or a first state (200a)) of the housing structure (201) can be described as an unfolded state (or unfolded state) of the electronic device (200) (or housing structure (201)). Within the first state (200a), the front of the first housing part (210), the front of the second housing part (220), and the front of the third housing part (230) can define the front of the electronic device (200). In the first state (200a), the front of the first housing part (210), the front of the second housing part (220), and the front of the third housing part (230) may face in the same direction. In the first state (200a), the electronic device (200) may provide the user with a large display area of the flexible display (240).
[0082] The first hinge structure (250) and the second hinge structure (260) can provide a second state (200b) of the electronic device (200). The second state (200b) of the electronic device (200) can be described as a state in which the electronic device (200) is partially folded and partially unfolded (or a single folding state or a half folding state). For example, in the second state (200b), the front of the second housing part (220) and the front of the third housing part (230) may face in the same direction, and the front of the first housing part (210) and the front of the second housing part (220) may face in opposite directions. For example, in the second state (200b), the first housing part (210) and the second housing part (220) may be folded, and the second housing part (220) and the third housing part (230) may be unfolded. In the second state (200b), the electronic device (200) can provide visual information through a part of the flexible display (240) (e.g., a third display area (240c)).
[0083] The electronic device (200) can change from a first state (200a) to a third state (200c) through a second state (200b). The electronic device (200) can change from a first state (200a) which is an unfolded state to a second state (200b) which is a partially unfolded state. For example, the electronic device (200) can change from a first state (200a) in which the first housing part (210), the second housing part (220), and the third housing part (230) face the same direction to a second state (200b) in which the front of the first housing part (210) faces the front of the second housing part (220). The electronic device (200) can change from a second state (200b) which is a partially unfolded state to a third state (200c) which is a folded state. For example, when changing from the second state (200b) to the third state (200c), the folded first housing part (210) and the second housing part (220) can be placed on the third housing part (230).
[0084] The first hinge structure (250) and the second hinge structure (260) can provide a third state (200c) of the electronic device (200) (or a third state (200c) of the housing structure (201). The third state (200c) of the electronic device (200) (or a third state (200c) of the housing structure (201)) can be described as a folded state (or a folded state or a multi-folded state) of the electronic device (200) (or the housing structure (201)). In the third state (200c), the front of the first housing part (210) and the front of the second housing part (220) may face in opposite directions, and the front of the second housing part (220) and the front of the third housing part (230) may face in opposite directions. In the third state (200c), the front of the first housing part (210) and the front of the third housing part (230) may face each other in the same direction. For example, in the third state (200c), the front of the second housing part (220) may face the front of the first housing part (210), and the front of the third housing part (230) may face the rear of the first housing part (210). In the third state (200c), the rear of the second housing part (220) may be exposed to the outside. A display (270) may be placed on the rear of the second housing part (220). In the third state (200c), the rear of the third housing part (230) may be exposed to the outside. A camera (275) may be placed on the rear of the third housing part (230). In the third state (200c), the electronic device (200) can be folded to improve portability and can provide visual information through a display (270) positioned on the rear of the second housing part (220).
[0085] The electronic device (200) may further include a key button (239). The key button (239) may be exposed from a structure (e.g., an opening) formed on the side of the third housing part (230) and may partially protrude outside the electronic device (200). The key button (239) may provide physical input to a processing circuit inside the electronic device (200) by pressure transmitted from the outside. The key button (239) may not be included in the electronic device (200) and may be implemented in other forms, such as a soft key displayed on a flexible display (240) or a display (270).
[0086] The key button (239) may be positioned on the side of the third housing part (230) so as to be exposed to the outside in the third state (200c). As the key button (239) is positioned on the side of the third housing part (230), it may be positioned in the direction in which the side of the third housing part (230) faces. Even if the display (270) in the third state (200c) is changed to the first state (200a) by a user, the position of the key button (239) positioned on the side of the third housing part (230) may not be moved. For example, referring to FIG. 2a, in the first state (200a), when the flexible display (240) is viewed from above, the key button (239) may be positioned on the right side. Referring to FIG. 2b, in the third state (200c), when viewing the display (270) from above, the key button (239) can be positioned on the right.
[0087] The flexible display (240) can define the appearance of the electronic device (200) at least partially. The flexible display (240) can be partially disposed within the housing structure (201). The flexible display (240) can define the front of the electronic device (200). The flexible display (240) may include a first unbendable portion (241), a second unbendable portion (242), a third unbendable portion (243), a first bendable portion (244), and a second bendable portion (245). The first unbendable portion (241) of the flexible display (240) can be disposed on the front of the first housing part (210). The second unbendable portion (242) of the flexible display (240) can be disposed on the front of the second housing part (220). A third unbendable portion (243) of the flexible display (240) may be placed on the front of the third housing part (230). A first bendable portion (244) of the flexible display (240) may be placed between the first unbendable portion (241) and the third unbendable portion (243) of the flexible display (240). For example, the first bendable portion (244) of the flexible display (240) may be placed on a first hinge structure (250) connecting the first housing part (210) and the second housing part (220). A second bendable portion (245) of the flexible display (240) may be placed between the second unbendable portion (242) and the third unbendable portion (243) of the flexible display (240). For example, the second bendable portion (245) of the flexible display (240) may be placed on a second hinge structure (260) connecting the second housing part (220) and the third housing part (230).
[0088] The first hinge structure (250) and the second hinge structure (260) may have the first unbendable portion (241) of the flexible display (240), the second unbendable portion (242) of the flexible display (240), and the third unbendable portion (243) of the flexible display (240) oriented substantially in the same direction. In the first state (200a), the first bendable portion (244) and the second bendable portion (245) may be positioned in substantially the same horizontal plane as the first unbendable portion (241), the second unbendable portion (242), and the third unbendable portion (243).
[0089] The first hinge structure (250) and the second hinge structure (260) can provide a second state (200b) of the electronic device (200). In the second state (200b), the first unbendable portion (241) of the flexible display (240) may face the second unbendable portion (242) of the flexible display (240), and the third unbendable portion (243) of the flexible display (240) may face the same direction as the second unbendable portion (242) of the flexible display (240). For example, the second unbendable portion (242) and the third unbendable portion (243) may be positioned substantially on the same horizontal plane.
[0090] In the second state (200b), the first bendable portion (244) of the flexible display (240) is bent by the first hinge structure (250), so that the first bendable portion (244) of the flexible display (240) can be folded such that the first unbendable portion (241) of the flexible display (240) and the second unbendable portion (242) of the flexible display (240) face in different directions.
[0091] In the second state (200b), the second bendable portion (245) of the flexible display (240) is maintained in an unfolded state by the second hinge structure (260), so that the second bendable portion (245) of the flexible display (240) can be unfolded such that the second unbendable portion (242) of the flexible display (240) and the third unbendable portion (243) of the flexible display (240) face in the same direction.
[0092] The first hinge structure (250) and the second hinge structure (260) can provide a third state (200c) of the electronic device (200). In the third state (200c), the second unbendable portion (242) of the flexible display (240) faces the first unbendable portion (241) of the flexible display (240), and the third unbendable portion (243) of the flexible display (240) may face the rear of the first housing part (210).
[0093] In the third state (200c), the first bendable portion (244) of the flexible display (240) is bent by the first hinge structure (250), so that the first bendable portion (244) of the flexible display (240) can be folded such that the first unbendable portion (241) of the flexible display (240) and the second unbendable portion (242) of the flexible display (240) face in different directions.
[0094] In the third state (200c), the second bendable portion (245) of the flexible display (240) is bent by the second hinge structure (260), so that the second bendable portion (245) of the flexible display (240) can be folded such that the second unbendable portion (242) of the flexible display (240) and the third unbendable portion (243) of the flexible display (240) face in different directions. The second bendable portion (245) may further include a first deformation portion (245a), a second deformation portion (245b), and a flat portion (245c). The first deformation portion (245a) may be positioned between the planar portion (245c) and the second unbendable portion (242), and the second deformation portion (245b) may be positioned between the planar portion (245c) and the third unbendable portion (243). The planar portion (245c) may be positioned between the first deformation portion (245a) and the second deformation portion (245b). The planar portion (245c) may be supported by a support plate (e.g., the support plate (364) of FIG. 3a) that is distinct from the hinge plates of the second hinge structure (260) (e.g., the third hinge plate (362) and the fourth hinge plate (363) of FIG. 3a). Regardless of the state of the electronic device (200), the planar portion (245c) may remain flat. The first deformation part (245a) and the second deformation part (245b) are unfolded in the first state (200a) and the second state (200b), and in the third state (200c), the first deformation part (245a) and the second deformation part (245b) can be bent so that the second unbendable part (242) and the third unbendable part (243) face in different directions. In the third state (200c), the first housing part (210) can be positioned between the second housing part (220) and the third housing part (230). In the third state (200c), the second bendable part (245) of the flexible display (240) positioned on the second hinge structure (260) can be partially facing the side (210c) of the first housing part (210).
[0095] The display area of the flexible display (240) may include a first display area (240a), a second display area (240b), and a third display area (240c). The display area represents an area capable of providing visual information from the flexible display (240). In a first state (200a), the entire display area of the flexible display (240) may be visible from the front of the housing structure (201). For example, in the first state (200a), the first display area (240a), the second display area (240b), and the third display area (240c) of the flexible display (240) may be visually exposed. The electronic device (200) may provide a large display area to the user that includes the first display area (240a), the second display area (240b), and the third display area (240c).
[0096] In the second state (200b), the display area of the flexible display (240) may be partially visible from the front of the third housing part (230). For example, the third display area (240c) may be visually exposed, while the first display area (240a) and the second display area (240b) may not be visually exposed.
[0097] In the third state (200c), the display area of the flexible display (240) may not be visible. For example, in the third state (200c), the first display area (240a), the second display area (240b), and the third display area (240c) of the flexible display (240) may not be visually exposed.
[0098] In a non-limiting example, when the flexible display (240) is used to display a screen within a first state (200a) of the electronic device (200), the first display area (240a), the second display area (240b), and the third display area (240c) of the flexible display (240) may be activated. In a non-limiting example, within a third state (200c), the first display area (240a), the second display area (240b), and the third display area (240c) of the flexible display (240) may be deactivated. In a non-limiting example, within a second state (200b) of the electronic device (200), when the flexible display (240) is used to display a screen, the third display area (240c) is activated, and the first display area (240a) and the second display area (240b) of the flexible display (240) may be deactivated.
[0099] In a non-limiting example, when the flexible display (240) is used to display a screen within a first state (200a) of the electronic device (200), the first display area (240a), the second display area (240b), and the third display area (240c) of the flexible display (240) may display visual information. In a non-limiting example, within the third state (200c), the first display area (240a), the second display area (240b), and the third display area (240c) of the flexible display (240) may provide a black image. As a non-limiting example, in a second state (200b) of the electronic device (200), when the flexible display (240) is used to display a screen, the third display area (240c) provides visual information, and the first display area (240a) and the second display area (240b) of the flexible display (240) may provide a black image.
[0100] FIG. 3a is a plan view of an electronic device with a flexible display removed according to an embodiment of the present disclosure. FIG. 3b is a rear view of an electronic device with a rear cover and a display removed according to an embodiment of the present disclosure.
[0101] Referring to FIGS. 3a and 3b, the electronic device (200) may include a first hinge structure (250) and a second hinge structure (260). The first width (w1) of the first hinge structure (250) may be narrower than the second width (w2) of the second hinge structure (260). The difference between the first width (w1) of the first hinge structure (250) and the second width (w2) of the second hinge structure (260) may be equal to or greater than the thickness of the first housing part (210). For example, the second hinge structure (260) may have a second width (w2) that is wider than the first width (w1) so that, according to the third state (200c), the first housing part (210) is positioned between the second housing part (220) and the third housing part (230). The first hinge structure (250) may be referred to as a narrow hinge structure in that it has a narrower width than the second hinge structure (260). The second hinge structure (260) may be referred to as a wide hinge structure in that it has a wider width than the first hinge structure (250).
[0102] The first hinge structure (250) may include a first set of gears (351), a first hinge plate (352), and a second hinge plate (353). The first hinge plate (352) may be coupled to a first support portion (211) of the first housing part (210). The second hinge plate (353) may be coupled to a second support portion (221) of the second housing part (220). The gears (g11, g12, g13, g14) included in the first set of gears (351) may be configured to rotate the first hinge plate (352) and the second hinge plate (353). For example, the gears (g11, g12, g13, g14) included in the first set of gears (351) can rotate the second hinge plate (353) (or the second housing part (220)) in conjunction with the rotation of the first hinge plate (352) (or the first housing part (210)). After the first hinge plate (352) (or the first housing part (210)) is rotated, the gears (g11, g12, g13, g14) included in the first set of gears (351) can be rotated according to the rotation of the first hinge plate (352) (or the first housing part (210)). The second hinge plate (353) (or the second housing part (220)) may be rotated in conjunction with the rotation of the first hinge plate (352) according to the rotation of the gears included in the first set of gears (351).

Depending on the first rotational direction (e.g., clockwise) of the first gear (g11), the second gear (g12) engaged with the first gear (g11) can be rotated in a second rotational direction (e.g., counterclockwise) opposite to the first rotational direction. Depending on the second rotational direction of the second gear (g12), the third gear (g13) engaged with the second gear (g12) can be rotated in the first rotational direction. Depending on the first rotational direction of the third gear (g13), the fourth gear (g14) can be rotated in the second rotational direction. As the first gear (g11) and the fourth gear (g14) rotate in different directions, the first housing part (210) connected to the first hinge plate (352) and the second housing part (220) connected to the second hinge plate (353) can be folded or unfolded.

The gears (g21, g22, g23, g24, g25, g26) included in the second set of gears (361) may be configured to rotate the third hinge plate (362) and the fourth hinge plate (363). For example, the gears (g21, g22, g23, g24, g25, g26) included in the second set of gears (361) can rotate the fourth hinge plate (363) (or the third housing part (230)) in conjunction with the rotation of the third hinge plate (362) (or the second housing part (220)). After the third hinge plate (362) (or the second housing part (220)) is rotated, the gears (g21, g22, g23, g24, g25, g26) included in the second set of gears (361) can be rotated according to the rotation of the third hinge plate (362) (or the second housing part (220)). The fourth hinge plate (363) (or the third housing part (230)) can be rotated in conjunction with the rotation of the third hinge plate (362) according to the rotation of the gears (g21, g22, g23, g24, g25, g26) included in the second set (361) of gears.

The second gear (g22), the third gear (g23), the fourth gear (g24), and the fifth gear (g25) may be positioned between the first gear (g21) and the sixth gear (g26). The first gear (g21), second gear (g22), third gear (g23), fourth gear (g24), fifth gear (g25), and sixth gear (g26) can be engaged sequentially. Depending on the first rotational direction (e.g., clockwise) of the first gear (g21), the second gear (g22) engaged with the first gear (g21) can be rotated in a second rotational direction (e.g., counterclockwise) opposite to the first rotational direction. Depending on the second rotational direction of the second gear (g22), the third gear (g23) engaged with the second gear (g22) can be rotated in the first rotational direction. Depending on the first rotational direction of the third gear (g23), the fourth gear (g24) can be rotated in the second rotational direction. Depending on the rotation of the fourth gear (g24) in the second rotational direction, the fifth gear (g25) engaged with the fourth gear (g24) can be rotated in the first rotational direction. Depending on the rotation of the fifth gear (g25) in the first rotational direction, the sixth gear (g26) engaged with the fifth gear (g25) can be rotated in the second rotational direction. As the first gear (g21) and the sixth gear (g26) rotate in different directions, the second housing part (220) connected to the third hinge plate (362) and the third housing part (230) connected to the fourth hinge plate (363) can be folded or unfolded.

The second flexible printed circuit board (390) may connect the printed circuit board in the housing part where the sub-printed circuit board (375) is placed with the sub-printed circuit board (375) by means of the second flexible printed circuit board (390).
[0112] Components within the electronic device (200) may be connected to at least one processor within the third printed circuit board (373) via flexible printed circuit boards (380, 390). For example, a signal received from an antenna placed in the third housing part (230) may be transmitted to the third printed circuit board (373) where at least one processor (e.g., processor (120)) (e.g., AP or CP) is placed via a signal path (a) provided by the first flexible printed circuit board (380). A driving circuit for a flexible display (240) placed in the first housing part (210) may be connected to the third printed circuit board (373) where at least one processor (e.g., AP) is placed via a sub-printed circuit board (375) and a signal path (b) provided by the first flexible printed circuit board (380). A driving circuit for a display (270) connected to a sub-printed circuit board (375) placed in a second housing part (220) can be electrically connected to a third printed circuit board (373) on which at least one processor (e.g., AP) is placed, through a signal path (c) provided by the sub-printed circuit board (375), the first flexible printed circuit board (380), and the second flexible printed circuit board (390).
[0113] The electronic device (200) may further include batteries (e.g., battery (189)). Each of the batteries may be attached to support parts (211, 221, 231) included in the housing parts (210, 220, 230). The support parts (211, 221, 231) may support rechargeable batteries.
[0114] The arrangement of hardware components is exemplary, and unlike the above, the rear camera (275) and the second printed circuit board (372) may be placed in the third housing part (230), and the third printed circuit board (373) may be placed in the second housing part (220).
[0115] The first housing part (210) and the third housing part (230) are shown to rotate in opposite directions relative to the second housing part (220), but are not limited thereto. For example, while changing from the first state (200a) to the third state (200c), the first housing part (210) may rotate counterclockwise relative to the second housing part (220), and the third housing part (230) may rotate counterclockwise relative to the second housing part (220). As the first housing part (210) and the third housing part (230) rotate in the same direction, a portion of the display area of the flexible display (240) in the second state may be visually exposed.

FIG. 4b shows the current flow of an electronic device in a multi-folded state during antenna operation according to an embodiment of the present disclosure. FIG. 4c is a graph showing the radiation efficiency of an electronic device in a multi-folded state and an unfolded state according to an embodiment of the present disclosure.
[0117] Referring to FIG. 4a, a multi-foldable electronic device (400) (hereinafter, electronic device (400)) (e.g., electronic device (200)) according to an embodiment of the present disclosure may include a foldable housing (401).
[0118] The foldable housing (401) may include a plurality of housing parts. Each of the plurality of housing parts may be rotatably coupled to an adjacent housing part so as to be able to switch between the multi-folded state (e.g., third state (200c)) and unfolded state (e.g., first state (200a)) of the foldable housing (401).
[0119] For example, the foldable housing (401) may include a first housing part (410) (e.g., a third housing part (230)), a second housing part (420) (e.g., a first housing part (210)), and a third housing part (430) (e.g., a second housing part (220)). For example, the first housing part (410) may be rotatably coupled to a first side of the third housing part (430). For example, the second housing part (420) may be rotatably coupled to a second side of the third housing part (430) opposite to the first side. The foldable housing (401) may include a first hinge structure (441) (e.g., a second hinge structure (260)) that rotatably connects a first housing part (410) and a third housing part (430), and a second hinge structure (442) (e.g., a first hinge structure (250)) that rotatably connects a second housing part (420) and a third housing part (430).

Although not illustrated, in the unfolded state of the electronic device (400) (e.g., first state (200a)), the first housing part (410), the second housing part (420), and the third housing part (430) may be located substantially on the same plane.

[0122] A second conductive portion (412) may be positioned between a first conductive portion (411) and a third conductive portion (413). The second conductive portion (412) may be spaced apart from the first conductive portion (411), and a first non-conductive portion (416) may be positioned between the first conductive portion (411) and the second conductive portion (412). For example, the first non-conductive portion (416) may extend from a first end of the first conductive portion (411) to a first end of the second conductive portion (412). A third conductive portion (413) may be spaced apart from the second conductive portion (412), and a second non-conductive portion (417) may be positioned between the second conductive portion (412) and the third conductive portion (413). For example, the second non-conductive portion (417) may extend from the second end of the second conductive portion (412) to the first end of the third conductive portion (413). The first conductive portion (411), the first non-conductive portion (416), the second conductive portion (412), the second non-conductive portion (417), and the third conductive portion (413) may form a part of the side of the first housing part (410), for example, the upper or lower side of the first housing part (410), without limitation.
[0123] In an embodiment of the present disclosure, the second housing part (420) may include a plurality of conductive portions forming at least a portion of the side of the second housing part (420), and one or more non-conductive portions interposed between the plurality of conductive portions. For example, the second housing part (420) may include a first conductive portion (421), a second conductive portion (422), a third conductive portion (423), a first non-conductive portion (426), and a second non-conductive portion (427).
[0124] A second conductive portion (422) may be positioned between a first conductive portion (421) and a third conductive portion (423). The second conductive portion (422) may be spaced apart from the first conductive portion (421), and a first non-conductive portion (426) may be positioned between the first conductive portion (421) and the second conductive portion (422). For example, the first non-conductive portion (426) may extend from a first end of the first conductive portion (421) to a first end of the second conductive portion (422). A third conductive portion (423) may be spaced apart from the second conductive portion (422), and a second non-conductive portion (427) may be positioned between the second conductive portion (422) and the third conductive portion (423). For example, the second non-conductive portion (427) may extend from the second end of the second conductive portion (422) to the first end of the third conductive portion (423). The first conductive portion (421), the first non-conductive portion (426), the second conductive portion (422), the second non-conductive portion (427), and the third conductive portion (423) may form a part of the side of the second housing part (420), for example, the upper or lower side of the second housing part (420), without limitation.
[0125] In an embodiment of the present disclosure, the third housing part (430) may include a plurality of conductive portions forming at least a portion of the side of the third housing part (430), and one or more non-conductive portions interposed between the plurality of conductive portions. For example, the third housing part (430) may include a first conductive portion (431), a second conductive portion (432), a third conductive portion (433), a first non-conductive portion (436), and a second non-conductive portion (437).
[0126] A second conductive portion (432) may be positioned between a first conductive portion (431) and a third conductive portion (433). The second conductive portion (432) may be spaced apart from the first conductive portion (431), and a first non-conductive portion (436) may be positioned between the first conductive portion (431) and the second conductive portion (432). For example, the first non-conductive portion (436) may extend from a first end of the first conductive portion (431) to a first end of the second conductive portion (432). A third conductive portion (433) may be spaced apart from the second conductive portion (432), and a second non-conductive portion (437) may be positioned between the second conductive portion (432) and the third conductive portion (433). For example, the second non-conductive portion (437) may extend from the second end of the second conductive portion (432) to the first end of the third conductive portion (433). The first conductive portion (431), the first non-conductive portion (436), the second conductive portion (432), the second non-conductive portion (437), and the third conductive portion (433) may form a part of the side of the third housing part (430), for example, the upper or lower side of the third housing part (430), without limitation.
[0127] In the multi-folded state of the electronic device (400), the first conductive portion (411) of the first housing part (410) may at least partially face the first conductive portion (421) of the second housing part (420). In the multi-folded state of the electronic device (400), the second conductive portion (412) of the first housing part (410) may at least partially face the second conductive portion (422) of the second housing part (420). In the multi-folded state of the electronic device (400), the third conductive portion (413) of the first housing part (410) may at least partially face the third conductive portion (423) of the second housing part (420).
[0128] In the multi-folded state of the electronic device (400), the first conductive portion (431) of the third housing part (430) may at least partially face the first conductive portion (421) of the second housing part (420). In the multi-folded state of the electronic device (400), the second conductive portion (432) of the third housing part (430) may at least partially face the second conductive portion (422) of the second housing part (420). In the multi-folded state of the electronic device (400), the third conductive portion (433) of the third housing part (430) may at least partially face the third conductive portion (423) of the second housing part (420).
[0129] In the multi-folded state of the electronic device (400), the first gap (g1) between the first housing part (410) and the second housing part (420) may be, for example, about 0.3 mm or less, without limitation. In the multi-folded state of the electronic device (400), the second gap (g2) between the second housing part (420) and the third housing part (430) may be, for example, about 0.6 mm or less, without limitation.
[0130] In an embodiment of the present disclosure, at least one of the first conductive portion (411), the second conductive portion (412), and the third conductive portion (413) of the first housing part (410) may be used as an antenna radiator of the electronic device (400). For example, a wireless communication circuit (e.g., a wireless communication module (192)) of the electronic device (400) may transmit and / or receive an RF (radio frequency) signal through at least one of the first conductive portion (411), the second conductive portion (412), and the third conductive portion (413) of the first housing part (410).
[0131] In an embodiment of the present disclosure, at least one of the first conductive portion (431), the second conductive portion (432), and the third conductive portion (433) of the third housing part (430) may be used as an antenna radiator of the electronic device (400). For example, the wireless communication circuit of the electronic device (400) may transmit and / or receive an RF (radio frequency) signal through at least one of the first conductive portion (431), the second conductive portion (432), and the third conductive portion (433) of the third housing part (430).
[0132] In the multi-folded state of the electronic device (400), when the conductive part of the first housing part (410) operates as an antenna, the current flowing through the conductive part of the first housing part (410) can be induced into the conductive part of the adjacent second housing part (420). Additionally, in the multi-folded state of the electronic device (400), when the conductive part of the third housing part (430) operates as an antenna, the current flowing through the conductive part of the third housing part (430) can be induced into the conductive part of the adjacent second housing part (420).
[0133] For example, referring to FIG. 4b, in a multi-folded state of the electronic device (400), the third conductive part (413) of the first housing part (410) can operate as an antenna (A3) including a feed point (F) and a ground point (G). In the drawings, the feed point (F) may be a point where the antenna (or the conductive part) is electrically connected to the wireless communication circuit, and the ground point (G) may be a point where the antenna (or the conductive part) is electrically connected to the ground of the electronic device (400). However, the locations of the feed point (F) and the ground point (G) are not limited by the illustrated example, and the locations of the feed point (F) and the ground point (G) may be interchanged or formed at a different location from the illustrated example.
[0134] As the third conductive part (413) operates as an antenna (A3), as illustrated in region (R), the current flowing through the third conductive part (413) of the first housing part (410) can be induced into the conductive parts of the second housing part (420) and the third housing part (430) adjacent to the third conductive part (413). To reduce the thickness of the electronic device (400), the first gap (g1) between the first housing part (410) and the second housing part (420), and the second gap (g2) between the second housing part (420) and the third housing part (430) can be reduced, and the induced current can be increased. The current induced into the adjacent conductive parts can create parasitic components and simultaneously reduce the efficiency of the antenna. For example, referring to FIG. 4c, the radiation efficiency (4C1) of the antenna (A3) in the multi-folded state of the electronic device (400) may be lower than the radiation efficiency (4C1) of the antenna (A3) in the unfolded state of the electronic device (400).
[0135] FIGS. 5a and 5b show a folded state of an electronic device according to a comparative example according to various embodiments of the present disclosure. FIG. 6 is a drawing showing an electronic device according to an embodiment of the present disclosure.
[0136] Referring to FIG. 5a, an electronic device (500) according to a comparative example may include a first housing part (510) and a second housing part (520) rotatable relative to the first housing part (510). When the electronic device (500) is folded so that the first housing part (510) and the second housing part (520) face each other, the conductive portion (511) of the first housing part (510) may operate as an antenna radiator. When the conductive portion (511) of the first housing part (510) operates as a first antenna radiator, the conductive portion (521) of the second housing part (520) may be used as a second antenna radiator by changing the electrical characteristics of the conductive portion (521) of the second housing part (520) aligned with the conductive portion (511) of the first housing part (510). Accordingly, the degradation of antenna performance that may occur as a result of current flowing in the conductive part (511) of the first housing part (510) being induced into the conductive part (521) of the second housing part (520) can be prevented or reduced.
[0137] Referring to FIG. 5b, the first housing part (510) of the electronic device (500) according to the comparative example may further include another conductive part (512) spaced apart from the conductive part (511). When the electronic device (500) is in a folded state, the conductive part (511) may function as an antenna (A51). Alternatively, when the electronic device (500) is in a folded state, the conductive part (511) and the other conductive part (512) may be electrically connected through an electrical path (550), and the conductive part (511) and the other conductive part (512) may function together as an antenna (A52). However, while this method may be effective for increasing the radiation performance of the antenna when the electronic device (500) is unfolded, it may be difficult to solve the problem of increased induced current when the electronic device (500) is in a folded state. In addition, the method of increasing the antenna volume by connecting a conductive part (511) and another conductive part (512) is effective for low band antennas (e.g., about 1 GHz or less), but is not suitable for application to antennas in a relatively high frequency band.
[0138] Referring to FIG. 6, since the first housing part (410) is connected to the second housing part (420) through the third housing part (430), it may be difficult to utilize the second housing part (420) facing the first housing part (410) as an antenna radiator when the electronic device (400) is in a folded state. This may be because when the wireless communication circuit of the electronic device (400) is placed in the first housing part (410), the physical distance between the wireless communication circuit and the second housing part (420) is long, resulting in significant loss. Even if the second housing part (420) is used as an antenna, the sides of the second housing part (420) are blocked by the first hinge structure (441) and the second hinge structure (442), and the top and bottom surfaces of the second housing part (420) are blocked by the first housing part (410) and the third housing part (430), so there are limitations in improving the antenna performance of the first housing part (410) by using the second housing part (420) as an antenna radiator.
[0139] Examples of electronic devices (400) capable of controlling currents generated from the first housing part (410) and the third housing part (430) by utilizing the second housing part (420), which is difficult to utilize as an antenna radiator, are shown below.

FIG. 7b shows housing parts of an electronic device in a multifolded state according to an embodiment of the present disclosure. FIG. 7c and FIG. 7d show an electronic device in a multifolded state according to an embodiment of the present disclosure. FIG. 7e shows a third housing part in which switching circuits are arranged according to an embodiment of the present disclosure.
[0141] Referring to FIGS. 7a, 7b, and 7c, the first conductive portion (411) of the first housing part (410) can operate as a first antenna (A1), the second conductive portion (412) of the first housing part (410) can operate as a second antenna (A2), and the third conductive portion (413) of the first housing part (410) can operate as a third antenna (A3).
[0142] The first conductive portion (431) of the third housing part (430) can operate as a fourth antenna (A1-1), the second conductive portion (432) of the third housing part (430) can operate as a fifth antenna (A2-1), and the third conductive portion (433) of the third housing part (430) can operate as a sixth antenna (A3-1). In FIG. 7a, the antennas (A1, A2, and A3) of the electronic device (400) are shown in a structure positioned at the top of the first housing part (410), but are not limited thereto. For example, the antennas (A1, A2, and A3) of the electronic device (400) may be provided at the bottom of the first housing part (410). As another example, in addition to the antennas (A1, A2, and A3) provided at the top of the first housing part (410), additional antennas may be provided at the bottom of the first housing part (410).
[0143] Referring to FIG. 7a, the antennas (A1-1, A2-1, and A3-1) of the electronic device (400) are shown in a structure where they are positioned on the top of the third housing part (430), but are not limited thereto. For example, the antennas (A1-1, A2-1, and A3-1) of the electronic device (400) may be provided on the bottom of the third housing part (430). As another example, in addition to the antennas (A1-1, A2-1, and A3-1) provided on the top of the third housing part (430), additional antennas may be provided on the bottom of the third housing part (430).
[0144] Referring to FIG. 7b, in a multi-folded state of the electronic device (400), each of the antennas (A1, A2, A3, A1-1, A2-1, and A3-1) of the electronic device (400) may operate separately or simultaneously with at least one of the antennas (A1, A2, A3, A1-1, A2-1, and A3-1).
[0145] Referring to FIG. 7b and FIG. 7c, an electronic device (400) according to an embodiment of the present disclosure may include a first switching circuit (450) that electrically connects a first conductive portion (421) and a second conductive portion (422) of a second housing part (420) and / or a second switching circuit (460) that electrically connects a second conductive portion (422) and a third conductive portion (423) of the second housing part (420). For example, circuits such as the first switching circuit (450) and the second switching circuit (460) may be placed within a printed circuit board (e.g., the printed circuit board (770) of FIG. 7e) within the electronic device (400) and may be electrically connected to the conductive portions (421, 422, and 423) of the second housing part (420).
[0146] In an embodiment of the present disclosure, the first switching circuit (450) may be configured to reduce and / or block the current induced from the conductive parts of the first housing part (410) to the conductive parts of the second housing part (420) when the conductive parts of the first housing part (410) operate as antennas. Additionally, the first switching circuit (450) may be configured to reduce and / or block the current induced from the conductive parts of the third housing part (430) to the conductive parts of the second housing part (420) when the conductive parts of the third housing part (430) operate as antennas. In an embodiment of the present disclosure, the first switching circuit (450) may include one or more filter circuits for reducing and / or blocking the current induced to the conductive parts of the second housing part (420). For example, the one or more filter circuits of the first switching circuit (450) may include lumped elements. For example, the one or more filter circuits may be circuits outside the first switching circuit (450), in which case the first switching circuit (450) may be electrically connected to and operated by the one or more filter circuits. For example, the first switching circuit (450) may include a filter or lumped elements, or may be electrically connected to and operated by such circuits or circuit components.
[0147] In an embodiment of the present disclosure, the second switching circuit (460) may be configured to reduce and / or block the current induced from the conductive parts of the first housing part (410) to the conductive parts of the second housing part (420) when the conductive parts of the first housing part (410) operate as antennas. Additionally, the second switching circuit (460) may be configured to reduce and / or block the current induced from the conductive parts of the third housing part (430) to the conductive parts of the second housing part (420) when the conductive parts of the third housing part (430) operate as antennas. In an embodiment of the present disclosure, the second switching circuit (460) may include one or more filter circuits for reducing and / or blocking the current induced to the conductive parts of the second housing part (420). For example, the one or more filter circuits of the second switching circuit (460) may include lumped elements. For example, the one or more filter circuits may be circuits outside the second switching circuit (460), in which case the second switching circuit (460) may be electrically connected to and operate with the one or more filter circuits. For example, the second switching circuit (460) may include a filter or lumped elements, or may be electrically connected to and operate with such circuits or circuit components.
[0148] For example, referring to FIG. 7d, the first switching circuit (450) may include at least one of the first circuit (451), the second circuit (452), the third circuit (453), and / or the fourth circuit (454). Each of the first circuit (451), the second circuit (452), the third circuit (453), and the fourth circuit (454) may be referred to as a filter or a filter circuit. For example, the filter or the filter circuit may be included in or connected to each of the first circuit (451), the second circuit (452), the third circuit (453), and the fourth circuit (454).
[0149] The first switching circuit (450) can optionally electrically connect the first conductive part (421) and the second conductive part (422) of the second housing part (420) through at least one of the first circuit (451), the second circuit (452), the third circuit (453), and / or the fourth circuit (454).
[0150] For example, the first switching circuit (450) can electrically connect the first conductive part (421) and the second conductive part (422) of the second housing part (420) through the first circuit (451) while the first conductive part (411) of the first housing part (410) is operating as the first antenna (A1). The first circuit (451) of the first switching circuit (450) can be configured to filter a signal having a frequency corresponding to the operating frequency of the first antenna (A1). For example, the first circuit (451) of the first switching circuit (450) may be configured to reduce and / or block the generation of the signal corresponding to the operating frequency of the first antenna (A1) from the first conductive part (411) of the first housing part (410) to the conductive parts (e.g., the first conductive part (421) and / or the second conductive part (422)) of the second housing part (420) by filtering the signal corresponding to the operating frequency of the first antenna (A1). The first circuit (451) may include one or more lumped elements configured to reduce and / or block the generation of the signal corresponding to the operating frequency of the first antenna (A1) from the first housing part (410) to the second housing part (420). For example, the first circuit (451) may include an LC filter (or LC filter circuit) having the operating frequency of the first antenna (A1) and / or a frequency band including the same as the cut-off frequency.
[0151] For example, the first switching circuit (450) can electrically connect the first conductive part (421) and the second conductive part (422) of the second housing part (420) through the second circuit (452) while the second conductive part (412) of the first housing part (410) is operating as the second antenna (A2). The second circuit (452) of the first switching circuit (450) can be configured to filter a signal having a frequency corresponding to the operating frequency of the second antenna (A2). For example, the second circuit (452) of the first switching circuit (450) may be configured to reduce and / or block the generation of the signal corresponding to the operating frequency of the second antenna (A2) from the second conductive part (412) of the first housing part (410) to the conductive parts (e.g., the first conductive part (421) and / or the second conductive part (422)) of the second housing part (420) by filtering the signal corresponding to the operating frequency of the second antenna (A2). The second circuit (452) may include one or more lumped elements configured to reduce and / or block the generation of the signal corresponding to the operating frequency of the second antenna (A2) from the first housing part (410) to the second housing part (420). For example, the second circuit (452) may include an LC filter (or LC filter circuit) having the operating frequency of the second antenna (A2) and / or a frequency band including the same as the cutoff frequency.

For example, the first antenna (A1) using the first conductive portion (411) of the first housing part (410) may be configured to operate in multiple bands. For example, the operating frequency of the first antenna (A1) using the first conductive portion (411) of the first housing part (410) may include a first frequency and a second frequency different from the first frequency. In this case, the first filter circuit (451) of the first switching circuit (450) corresponding to the first conductive portion (411) (or the first antenna (A1)) may include a filter circuit configured to cut off the first frequency and another filter circuit configured to cut off the second frequency, or may include a single filter circuit configured to cut off the first frequency and the second frequency.

For example, a first switching circuit (450) and a second switching circuit (460) may be disposed on the printed circuit board (770).
[0165] In an embodiment of the present disclosure, the first conductive portion (421) of the second housing part (420) may include a portion (721a) that protrudes inwardly from the second housing part (420) (or protrudes toward the printed circuit board (770)).

[0169] In an embodiment of the present disclosure, the second switching circuit (460) may be electrically connected to the second portion (722b) of the second conductive portion (422) and the portion (723a) of the third conductive portion (423).
[0170] FIG. 8a shows an electronic device in a multi-folded state according to an embodiment of the present disclosure. FIG. 8b shows the current flow of an electronic device according to a comparative example and the current flow of an electronic device according to an embodiment when a first antenna is operated according to an embodiment of the present disclosure. FIG. 8c shows the radiation efficiency of the first antenna of the electronic device according to a comparative example and the radiation efficiency of the first antenna of the electronic device according to a comparative example according to an embodiment of the present disclosure.
[0171] Block (8B1) of FIG. 8b shows the current flow of an electronic device according to a comparative example that does not include a first switching circuit (450) when the first antenna (A1) is in operation, and block (8B2) of FIG. 8b shows the current flow of an electronic device (400) according to an embodiment that includes a first switching circuit (450) when the first antenna (A1) is in operation.

[0173] Referring to FIG. 8a, in a multi-folded state of the electronic device (400), the first conductive portion (411) of the first housing part (410) can operate as the first antenna (A1). The first switching circuit (450) can reduce and / or block current from being induced from the first conductive portion (411) of the first housing part (410) to the conductive portions of the second housing part (420) (e.g., the first conductive portion (421) and / or the second conductive portion (422)) when the first antenna (A1) operates in the multi-folded state of the electronic device (400). For example, the first antenna (A1) can operate in a specific frequency band of about 1 GHz or less (e.g., a specific band within the low band). For example, the first switching circuit (450) can electrically connect the first conductive part (421) and the second conductive part (422) of the second housing part (420) through a filter circuit (e.g., a band stop filter) (e.g., the first filter circuit (451)) having a cutoff frequency of about 1 GHz when the first antenna (A1) is operating.
[0174] Accordingly, the current flowing through the housing part operating as an antenna may be reduced and / or prevented from being induced into an adjacent housing part. For example, as illustrated in FIG. 8b, when the first antenna (A1) is operating, the current (block (8B2)) induced from the first conductive part (411) of the electronic device (400) according to one embodiment including the first switching circuit (450) to the first conductive part (421) and the second conductive part (422) of the second housing part (420) may be reduced compared to the current (block (8B1)) induced from the first conductive part (411) of the electronic device according to a comparative example not including the first switching circuit (450) to the first conductive part (421) and the second conductive part (422) of the second housing part (420).
[0175] Accordingly, the performance of the first antenna (A1) can be improved. For example, as shown in FIG. 8c, the total radiation efficiency (graph (8C2)) of the first antenna (A1) of an electronic device (400) according to one embodiment including the first switching circuit (450) can be improved compared to the total radiation efficiency (graph (8C1)) of the first antenna (A1) of an electronic device according to a comparative example not including the first switching circuit (450) (e.g., within a low band of about 1 GHz or less).

[0179] Referring to FIG. 9a, in a multi-folded state of the electronic device (400), the second conductive portion (432) of the third housing part (430) can operate as a fifth antenna (A2-1). The first switching circuit (450) can reduce and / or block current from being induced from the second conductive portion (432) of the third housing part (430) to the conductive portions of the second housing part (420) (e.g., the first conductive portion (421) and / or the second conductive portion (422)) when the fifth antenna (A2-1) operates in the multi-folded state of the electronic device (400). For example, the fifth antenna (A2-1) can operate in a specific frequency band of about 1.5 GHz or less (e.g., the GPS L1 band of 1575.42 MHz). For example, the first switching circuit (450) can electrically connect the first conductive part (421) and the second conductive part (422) of the second housing part (420) through a filter circuit (e.g., high pass filter) (e.g., fourth filter circuit (454)) configured to cut off a frequency band of about 1.5 GHz or less when the fifth antenna (A2-1) is operating.
[0180] Accordingly, the current flowing through the housing part operating as an antenna may be reduced and / or prevented from being induced into an adjacent housing part. For example, as illustrated in FIG. 9b, when the fifth antenna (A2-1) is in operation, the current (block (9B2)) induced from the second conductive part (432) of the third housing part (430) of the electronic device (400) according to one embodiment including the first switching circuit (450) to the first conductive part (421) and the second conductive part (422) of the second housing part (420) may be reduced compared to the current (block (9B1)) induced from the second conductive part (432) of the third housing part (430) of the electronic device according to a comparative example not including the first switching circuit (450) to the first conductive part (421) and the second conductive part (422) of the second housing part (420).
[0181] Accordingly, the performance of the fifth antenna (A2-1) can be improved. For example, as illustrated in FIG. 9c, the total radiation efficiency (graph (9C2)) of the fifth antenna (A2-1) of an electronic device (400) according to one embodiment including the first switching circuit (450) can be improved compared to the total radiation efficiency (graph (9C1)) of the fifth antenna (A2-1) of an electronic device according to a comparative example not including the first switching circuit (450) (e.g., within the GPS L1 band of 1575.42 MHz).

[0186] Referring to FIG. 10a, in a multi-folded state of the electronic device (400), the third conductive part (413) of the first housing part (410) can operate as a third antenna (A3). Additionally, in a multi-folded state of the electronic device (400), the third conductive part (433) of the third housing part (430) can operate as a sixth antenna (A3-1). The second switching circuit (460) can reduce and / or block current from being induced from the third conductive part (413) of the first housing part (410) to the conductive parts of the second housing part (420) (e.g., the second conductive part (422) and / or the third conductive part (423)) when the third antenna (A3) operates in a multi-folded state of the electronic device (400). Additionally, the second switching circuit (460) can reduce and / or block current from being induced from the third conductive part (433) of the third housing part (430) to the conductive parts of the second housing part (420) (e.g., the second conductive part (422) and / or the third conductive part (423)) when the sixth antenna (A3-1) is operated in the multi-folded state of the electronic device (400).
[0187] For example, the third antenna (A3) and the sixth antenna (A3-1) may each be configured to operate in a specific frequency band within a mid band of about 1.0 GHz or more and 2.3 GHz or less, and / or a specific frequency band within a high band of about 2.3 GHz or more. For example, the second switching circuit (460) may electrically connect the second conductive part (422) and the third conductive part (423) of the second housing part (420) through a filter circuit (e.g., a band stop filter) (e.g., the second filter circuit (462) and / or the fourth filter circuit (464)) configured to cut off a frequency band of about 2.0 GHz when the third antenna (A3) and / or the sixth antenna (A3-1) are operating.
[0188] Accordingly, the induction of current flowing through the housing part acting as an antenna into an adjacent housing part can be reduced and / or prevented. For example, as illustrated in FIG. 10b, when the third antenna (A3) and / or the sixth antenna (A3-1) is operated, the current (block (10B2)) induced from the third conductive part (413) of the first housing part (410) and / or the third conductive part (433) of the third housing part (430) of the electronic device (400) according to one embodiment including the second switching circuit (460) to the first conductive part (421), the second conductive part (422), and the third conductive part (423) of the second housing part (420) is such that the current induced from the third conductive part (413) of the first housing part (410) of the electronic device according to a comparative example not including the second switching circuit (460) to the first conductive part (421), the second conductive part (422), and the third conductive part (423) of the second housing part (420) The current (block (10B1)) can be reduced.
[0189] Accordingly, the performance of the third antenna (A3) and the sixth antenna (A3-1) can be improved. For example, as shown in FIG. 10c, the total radiation efficiency (graph (10C2)) of the third antenna (A3) of the electronic device (400) according to one embodiment including the second switching circuit (460) can be improved compared to the total radiation efficiency (graph (10C1)) of the third antenna (A3) of the electronic device according to a comparative example not including the second switching circuit (460) (e.g., within the mid-band and high-band). For example, as illustrated in FIG. 10d, the total radiation efficiency (graph (10D2)) of the sixth antenna (A3-1) of the electronic device (400) according to one embodiment including the second switching circuit (460) can be improved compared to the total radiation efficiency (graph (10D1)) of the sixth antenna (A3-1) of the electronic device according to a comparative example not including the second switching circuit (460) (e.g., within the mid-band and high-band).

[0191] Graph (11B1) of FIG. 11b shows the total radiation efficiency of the second antenna (A2) of an electronic device according to a comparative example that does not include the second switching circuit (460), and graph (11B2) of FIG. 11b shows the total radiation efficiency of the second antenna (A2) of an electronic device (400) according to an embodiment that includes the second switching circuit (460).
[0192] Referring to FIG. 11a, in a multi-folded state of the electronic device (400), the second conductive part (412) of the first housing part (410) can operate as a second antenna (A2), the third conductive part (413) of the first housing part (410) can operate as a third antenna (A3), the second conductive part (432) of the third housing part (430) can operate as a fifth antenna (A2-1), and the third conductive part (433) of the third housing part (430) can operate as a sixth antenna (A3-1).
[0193] The second switching circuit (460) may include one or more filter circuits (e.g., at least one of filter circuits (461, 462, 463, and 464)) configured to reduce and / or block the induced current resulting from the operation of at least one of the second antenna (A2), the third antenna (A3), the fifth antenna (A2-1), and the sixth antenna (A3-1). Depending on the antenna being operated, the second switching circuit (460) may optionally electrically connect the second conductive portion (422) and the third conductive portion (423) of the second housing part (420) through the one or more filter circuits.
[0194] For example, the second switching circuit (460) can electrically connect the second conductive part (422) and the third conductive part (423) of the second housing part (420) through a filter circuit (e.g., a high-pass filter) (e.g., a third filter circuit (463)) configured to cut off a frequency band of about 1.5 GHz or less when the fifth antenna (A2-1) operates in a specific frequency band of about 1.5 GHz or less. Accordingly, the performance of the fifth antenna (A2-1) can be improved (e.g., graph (9C2) of FIG. 9c).
[0195] For example, the second switching circuit (460) can electrically connect the second conductive part (422) and the third conductive part (423) of the second housing part (420) through a filter circuit (e.g., a band stop filter) (e.g., the second filter circuit (462) and / or the fourth filter circuit (464)) configured to cut off a frequency band of about 2.0 GHz when the third antenna (A3) and / or the sixth antenna (A3-1) are operating in a specific frequency band within a mid band of about 1.0 GHz or more and 2.3 GHz or less and / or a specific frequency band within a high band of about 2.3 GHz or more, as described with reference to FIG. 10a, FIG. 10b, FIG. 10c, and FIG. 10d. Accordingly, the performance of the third antenna (A3) and the sixth antenna (A3-1) can be improved (e.g., graph (10C2) of FIG. 10c and graph (10D2) of FIG. 10d).
[0196] For example, the second antenna (A2) can operate in a specific frequency band of about 2.7 GHz or higher (e.g., a specific frequency band within NR FR1 (new radio frequency 1) of 7.125 GHz or lower), and the second switching circuit (460) can electrically connect the second conductive part (422) and the third conductive part (423) of the second housing part (420) through a filter circuit (e.g., a high-pass filter) (e.g., the first filter circuit (461)) configured to cut off a frequency band of about 2.7 GHz or lower when the second antenna (A2) is operating. Accordingly, when the second antenna (A2) is operating, the current of the second antenna (A2) being induced from the first housing part (410) to the second housing part (420) can be reduced and / or prevented. Accordingly, the performance of the second antenna (A2) can be improved. For example, as illustrated in FIG. 11b, the total radiation efficiency (graph (11B2)) of the second antenna (A2) of an electronic device (400) according to one embodiment including the second switching circuit (460) can be improved compared to the total radiation efficiency (graph (11B1)) of the second antenna (A2) of an electronic device according to a comparative example not including the second switching circuit (460) (e.g., within NR FR1).
[0197] FIG. 12a shows an electronic device in a multi-folded state according to an embodiment of the present disclosure. FIG. 12b shows the power flow during the operation of the third antenna of an electronic device according to a comparative example and the power flow during the operation of the third antenna of an electronic device according to an embodiment of the present disclosure. FIG. 12c is a graph showing the radiation efficiency of the third antenna of an electronic device according to a comparative example and the radiation efficiency of the third antenna of an electronic device according to an embodiment of the present disclosure.
[0198] 12B1 of FIG. 12b represents the power flow during operation of the third antenna (A3) of an electronic device of a comparative example that does not include a first switching circuit (450) and a second switching circuit (460), and 12B2 of FIG. 12b represents the power flow during operation of the third antenna (A3) of an electronic device (400) according to an embodiment of the present disclosure when the first conductive part (421) and the second conductive part (422) of the second housing part (420) are electrically connected through the first switching circuit (450) and the second conductive part (422) and the third conductive part (423) of the second housing part (420) are electrically connected through the second switching circuit (460).
[0199] Referring to FIG. 12a, in a multi-folded state of an electronic device (400) according to an embodiment of the present disclosure, a third conductive portion (413) of a first housing part (410) can operate as a third antenna (A3). A second switching circuit (460) can electrically connect the second conductive portion (422) and the third conductive portion (423) of the second housing part (420) through a specific filter circuit (e.g., a second filter circuit (462)) so that when the third antenna (A3) is operated, the current of the third antenna (A3) is reduced and / or blocked from being induced into the second conductive portion (422) and the third conductive portion (423) of the second housing part (420).
[0200] Since the first conductive part (421) and the second conductive part (422) of the second housing part (420) can also serve as pathways for the induced current, the first switching circuit (450) can electrically connect the first conductive part (421) and the second conductive part (422) of the second housing part (420) through the specific filter circuit when the third antenna (A3) is in operation.
[0201] For example, when the third antenna (A3) operates in a specific frequency band within the mid-band of 1 GHz to 2.3 GHz and / or a specific frequency band within the high-band of 2.3 GHz or higher, the second switching circuit (460) can electrically connect the second conductive part (422) and the third conductive part (423) of the second housing part (420) through a filter circuit configured to cut off a frequency band of about 2 GHz, and additionally, the first switching circuit (450) can electrically connect the first conductive part (421) and the second conductive part (422) of the second housing part (420) through a filter circuit configured to cut off a frequency band of about 2 GHz.
[0202] When the third antenna (A3) is in operation, the second conductive part (422) and the third conductive part (423) of the second housing part (420) are electrically connected through the second switching circuit (460), and the first conductive part (421) and the second conductive part (422) of the second housing part (420) are additionally electrically connected through the first switching circuit (450), thereby improving the performance of the third antenna (A3). For example, referring to 12B1 in FIG. 12b, as shown in region (R1), the amount of power coupled to the neighboring housing part when the third antenna (A3) is in operation can be increased. In contrast, referring to 12B2 in FIG. 12b, as shown in region (R2), the conductive parts of the second housing part (420) are connected through the first switching circuit (450) and the second switching circuit (460), thereby improving the radiation contribution of the first housing part (410) corresponding to the third antenna (A3).
[0203] Referring to FIG. 12c together with FIG. 12a, graph (12C1) shows the radiation efficiency of the third antenna (A3) of an electronic device according to a comparative example that does not include the first switching circuit (450) and the second switching circuit (460).
[0204] Graph (12C2) shows the radiation efficiency of the third antenna (A3) when the second conductive part (422) and the third conductive part (423) of the second housing part (420) are electrically connected through the second switching circuit (460), and the first conductive part (421) and the second conductive part (422) of the second housing part (420) are not electrically connected through the first switching circuit (450).
[0205] Graph (12C3) shows the radiation efficiency of the third antenna (A3) when the second conductive part (422) and the third conductive part (423) of the second housing part (420) are electrically connected through the second switching circuit (460), and the first conductive part (421) and the second conductive part (422) of the second housing part (420) are electrically connected through the first switching circuit (450).
[0206] By comparing graph (12C1) and graph (12C2), the radiation efficiency of the third antenna (A3) can be improved by electrically connecting the second conductive part (422) and the third conductive part (423) of the second housing part (420) through the second switching circuit (460). Additionally, by comparing graph (12C2) and graph (12C3), the radiation efficiency of the third antenna (A3) can be improved by additionally electrically connecting the first conductive part (421) and the second conductive part (422) of the second housing part (420) through the first switching circuit (450) (e.g., at a frequency of about 2.45 GHz or higher).
[0207] FIG. 13a shows an electronic device in a multi-folded state according to an embodiment of the present disclosure. FIG. 13b shows the current flow during the operation of the first antenna of an electronic device according to a comparative example and the current flow during the operation of the first antenna of an electronic device according to an embodiment of the present disclosure. FIG. 13c shows the radiation efficiency of the first antenna of an electronic device according to a comparative example and the radiation efficiency of the first antenna of an electronic device according to an embodiment of the present disclosure.
[0208] Block (13B1) of FIG. 13b shows the current flow during operation of the first antenna (A1) of an electronic device according to a comparative example, which does not include the first switching circuit (1350) and the second switching circuit (1360).
[0209] Block (13B2) of FIG. 13b shows the current flow when the first conductive part (1321) and the second conductive part (1322) of the second housing part (1320) are electrically connected through the first switching circuit (1350) of the electronic device (1300) according to an embodiment of the present disclosure when the first antenna (A1) is operated.
[0210] The graph (13C1) of FIG. 13c shows the radiation efficiency of the first antenna (A1) of an electronic device according to a comparative example that does not include the first switching circuit (1350) and the second switching circuit (1360).
[0211] The graph (13C2) of FIG. 13c shows the radiation efficiency of the first antenna (A1) of the electronic device (1300) according to an embodiment of the present disclosure when the first conductive part (1321) and the second conductive part (1322) of the second housing part (1320) are electrically connected through the first switching circuit (1350).
[0212] With reference to the prior drawings, it has been described that the first housing part (410) and the second housing part (420) of the electronic device (400) are each rotatably connected to the third housing part (430), but this is not limited thereto. For example, with reference to FIG. 13a, an electronic device (1300) according to an embodiment of the present disclosure may include a first housing part (1310), a second housing part (1320) rotatably coupled to the first housing part (1310), and a third housing part (1330) rotatably coupled to the second housing part (1320). In a multi-folded state of the electronic device (1300), the second housing part (1320) may be placed on the first housing part (1310), and the third housing part (1330) may be placed on the second housing part (1320). The electronic device (1300) may include a first hinge structure (1341) that rotatably connects a first housing part (1310) and a second housing part (1320), and a second hinge structure (1342) that rotatably connects a second housing part (1320) and a third housing part (1330).
[0213] With respect to the first housing part (1310) of the electronic device (1300), the description of the first housing part (410) of the electronic device (400) may be applied in a substantially identical, similar, or corresponding manner, except that the first housing part (1310) is connected to the second housing part (1320) rather than the third housing part (1330). For example, the first housing part (1310) of the electronic device (1300) may include a first conductive part (1311) (e.g., first conductive part (411)), a second conductive part (1312) (e.g., second conductive part (412)), a third conductive part (1313) (e.g., third conductive part (413)), a first non-conductive part (1316) (e.g., first non-conductive part (416)), and a second non-conductive part (1317) (e.g., second non-conductive part (417)).
[0214] With respect to the second housing part (1320) of the electronic device (1300), the description of the second housing part (420) of the electronic device (400) may be applied in a substantially identical, similar, or corresponding manner, except that the second housing part (1320) is connected to the first housing part (1310) and the third housing part (1330), not only the third housing part (1330). For example, the second housing part (1320) of the electronic device (1300) may include a first conductive part (1321) (e.g., first conductive part (421)), a second conductive part (1322) (e.g., second conductive part (422)), a third conductive part (1323) (e.g., third conductive part (423)), a first non-conductive part (1326) (e.g., first non-conductive part (426)), and a second non-conductive part (1327) (e.g., second non-conductive part (427)).
[0215] With respect to the third housing part (1330) of the electronic device (1300), the description of the third housing part (430) of the electronic device (400) may be applied in a substantially identical, similar, or corresponding manner, except that the third housing part (1330) is connected only to the second housing part (1320) and not to the first housing part (1310) and the second housing part (1320). For example, a third housing part (1330) of an electronic device (1300) may include a first conductive part (1331) (e.g., first conductive part (431)), a second conductive part (1332) (e.g., second conductive part (432)), a third conductive part (1333) (e.g., third conductive part (433)), a first non-conductive part (1336) (e.g., first non-conductive part (436)), and a second non-conductive part (1337) (e.g., second non-conductive part (437)).
[0216] According to an embodiment of the present disclosure, the electronic device (1300) may include a first switching circuit (1350) and a second switching circuit (1360). For the first switching circuit (1350) and the second switching circuit (1360), the description of the first switching circuit (450) and the second switching circuit (460) described above may be applied substantially identically, similarly, or in a corresponding manner. For example, the first switching circuit (1350) may be configured to reduce and / or block the induction of current from the first antenna (A1) to the conductive parts (1321, 1322, and 1323) of the second housing part (1320) adjacent to the first housing part (1310) when the first conductive part (1311) of the first housing part (1310) operates as the first antenna (A1) in a multi-folded state of the electronic device (1300). For example, if the first antenna (A1) operates in a specific frequency band within a low band of 1 GHz or less, the first switching circuit (1350) can electrically connect the first conductive part (1321) and the second conductive part (1322) of the second housing part (1320) through a filter circuit (e.g., a band stop circuit) (e.g., the first filter circuit (451)) configured to cut off a frequency of about 1 GHz. Accordingly, with reference to FIG. 13b, the amount of current (block (13B2)) induced in the second housing part (1320) and the third housing part (1330) of an electronic device of a comparative example that does not include the first switching circuit (1350) and the second switching circuit (1360) when the first antenna (A1) is operated can be reduced compared to the amount of current (block (13B1)) induced in the second housing part (1320) and the third housing part (1330) when the first conductive part (1321) and the second conductive part (1322) of the second housing part (1320) are electrically connected through the first switching circuit (1350).Additionally, with reference to FIG. 13c, the radiation efficiency (graph (13C2)) of the first antenna (A1) of an electronic device (1300) according to one embodiment in which the first conductive part (1321) and the second conductive part (1322) of the second housing part (1320) are electrically connected through the first switching circuit (1350) can be improved compared to the radiation efficiency (graph (13C1)) of the first antenna (A1) of an electronic device (13C1) of a comparative example that does not include the first switching circuit (1350) and the second switching circuit (1360).
[0217] FIG. 14a shows an electronic device in a multi-folded state according to an embodiment of the present disclosure. FIG. 14b shows the current flow during the operation of the third antenna of an electronic device according to a comparative example and the current flow during the operation of the third antenna of an electronic device according to an embodiment of the present disclosure. FIG. 14c shows the radiation efficiency of the third antenna of an electronic device according to a comparative example and the radiation efficiency of the third antenna of an electronic device according to an embodiment of the present disclosure. FIG. 14d shows the radiation efficiency of the sixth antenna of an electronic device according to a comparative example and the radiation efficiency of the sixth antenna of an electronic device according to an embodiment of the present disclosure.

[0220] The graph (14C1) of FIG. 14c shows the radiation efficiency of the third antenna (A3) of an electronic device according to a comparative example, which does not include the first switching circuit (1451) and the second switching circuit (1452).
[0221] The graph (14C2) of FIG. 14c shows the radiation efficiency of the third antenna (A3) of the electronic device (400) according to an embodiment of the present disclosure when the second conductive part (422) and the third conductive part (423) of the second housing part (420) are grounded through the first switching circuit (1451) and the second switching circuit (1452), respectively.
[0222] The graph (14D1) of FIG. 14d shows the radiation efficiency of the sixth antenna (A3-1) of an electronic device according to a comparative example, which does not include the first switching circuit (1451) and the second switching circuit (1452).
[0223] The graph (14D2) of FIG. 14d shows the radiation efficiency of the sixth antenna (A3-1) of the electronic device (400) according to an embodiment of the present disclosure when the second conductive part (422) and the third conductive part (423) of the second housing part (420) are grounded through the first switching circuit (1451) and the second switching circuit (1452), respectively.
[0224] Referring to FIG. 14a, according to one embodiment, the electronic device (400) may include a first switching circuit (1451) and a second switching circuit (1452) instead of the second switching circuit (460) described above.
[0225] The first switching circuit (1451) may be an example configuration in which the aforementioned second switching circuit (460) is electrically connected to the ground of the electronic device (400) (e.g., a conductive region of the printed circuit board (770) operating as at least part of the ground) rather than the third conductive part (423) of the second housing part (420).
[0226] The second switching circuit (1452) may be an example of a configuration in which the aforementioned second switching circuit (460) is electrically connected to the ground of the electronic device (400) rather than the second conductive part (422) of the second housing part (420).
[0227] For example, when the third antenna (A3) and / or the sixth antenna (A3-1) is in operation, the first switching circuit (1451) may electrically connect the second conductive portion (422) of the second housing part (420) to a specific filter circuit connected to the ground (e.g., a band-pass filter configured to cut off a frequency band of about 2 GHz to about 3 GHz). For example, when the third antenna (A3) and / or the sixth antenna (A3-1) is in operation, the first switching circuit (1451) may electrically connect the second conductive portion (422) of the second housing part (420) and the ground through the specific filter circuit (e.g., a band-pass filter configured to cut off a frequency band of about 2 GHz to about 3 GHz).
[0228] For example, when the third antenna (A3) and / or the sixth antenna (A3-1) is in operation, the second switching circuit (1452) may electrically connect the third conductive part (423) of the second housing part (420) to a specific filter circuit connected to the ground (e.g., a band-pass filter configured to cut off a frequency band of about 2 GHz to about 3 GHz). When the third antenna (A3) and / or the sixth antenna (A3-1) is in operation, the second switching circuit (1452) may electrically connect the third conductive part (423) of the second housing part (420) and the ground through the specific filter circuit (e.g., a band-pass filter configured to cut off a frequency band of about 2 GHz to about 3 GHz).
[0229] Accordingly, with reference to FIG. 14b, the amount of current (block (14B1)) induced into the third conductive part (433) of the third housing part (430) during the operation of the third antenna (A3) of the electronic device (400) according to one embodiment, when the third antenna (A3) of the electronic device according to one embodiment is operated, can be reduced by electrically connecting the second conductive part (422) and the third conductive part (423) of the second housing part (420) to ground through the first switching circuit (1451) and the second switching circuit (1452), respectively.
[0230] Additionally, with reference to FIG. 14c, the radiation efficiency (graph (14C2)) of the third antenna (A3) of an electronic device (400) according to one embodiment in which the second conductive part (422) and the third conductive part (423) of the second housing part (420) are electrically connected to ground through the first switching circuit (1451) and the second switching circuit (1452), respectively, can be improved compared to the radiation efficiency (graph (14C1)) of the third antenna (A3) of an electronic device (400) of a comparative example that does not include the first switching circuit (1451) and the second switching circuit (1452).
[0231] Additionally, with reference to FIG. 14d, the radiation efficiency (graph (14D2)) of the sixth antenna (A3-1) of an electronic device (400) according to one embodiment in which the second conductive part (422) and the third conductive part (423) of the second housing part (420) are electrically connected to ground through the first switching circuit (1451) and the second switching circuit (1452), respectively, can be improved compared to the radiation efficiency (graph (14D1) of the sixth antenna (A3-1) of an electronic device of a comparative example that does not include the first switching circuit (1451) and the second switching circuit (1452).
