[0031] As the demand for portable electronic devices increases, various types of electronic devices capable of meeting user needs are being developed. For example, foldable electronic devices that can be folded by the user by including multiple housings are being developed, rather than being limited to conventional bar-shaped electronic devices. By including a flexible display, foldable electronic devices can provide the user with a large screen when unfolded and offer enhanced portability by being carried when folded. In foldable electronic devices, interference may occur in the transmission and reception of RF signals by the conductive part of the electronic device facing the antenna radiator placed at one end of the electronic device when the device is in a folded state. The RF signal radiated by the antenna radiator may generate a first resonance based on the length of the radiator (e.g., antenna radiator resonance) and a second resonance based on the size of the electronic device (e.g., length of the electronic device) (e.g., structural resonance). The first resonance (e.g., antenna radiator resonance) may be affected by the second resonance (e.g., structural resonance).

[0066] According to one embodiment, the housing (200) may provide a space and a support member in which internal components of the electronic device (101) can be seated. The support member may fix and / or support the components seated in the internal space of the housing (200).

[0067] According to one embodiment, the state of the electronic device (101) may be changed by rotation of the first housing (201) and / or the third housing (203). For example, the electronic device (101) may be changed to one of a first state (101a), a second state (101b), and a third state (101c).

[0068] For example, the electronic device (101) in the first state (101a) may have the housing (200) in an unfolded state. For example, the electronic device (101) in the first state (101a) may have the first housing (201) and the third housing (203) unfolded from the second housing (202). For example, the electronic device (101) in the first state (101a) may have the front of the first housing (201) rotated so that it is away from the front of the second housing (202), and the front of the third housing (203) rotated so that it is away from the front of the second housing (202). For example, the electronic device (101) in the first state (101a) may have the display (160) placed across the first housing (201), the second housing (202), and the third housing (203) in an unfolded state.

[0069] For example, the electronic device (101) in the second state (101b) may be in a state where the front of one of the first housing (201) or the third housing (203) is rotated so that it approaches the front of the second housing (202), and the front of the other housing is rotated so that it moves away from the front of the second housing (202). For example, the electronic device in the second state (101b) may be in a state where the front of the first housing (201) faces the front of the second housing (202), and the front of the third housing (203) faces the same direction as the front of the second housing (202). For example, the electronic device in the second state (101b) may be in a state where the front of the third housing (203) faces the front of the second housing (202), and the front of the first housing (201) faces the same direction as the front of the second housing (202).

[0070] For example, the electronic device (101) in the third state (101c) may be in a state where the front of the first housing (201) and the front of the third housing (203) are rotated so that they are close to the front of the second housing (202). For example, the electronic device (101) in the third state (101c) may be in a state where the front of the first housing (201) and the front of the third housing (203) are adjacent to the front of the second housing (202). For example, the electronic device (101) in the third state (101c) may be in a state where the front of the first housing (201) and the front of the third housing (203) face the front of the second housing (202). For example, the electronic device (101) in the third state (101c) may be in a state where the first side portion (201a) of the first housing (201) is adjacent to the fourth side portion (203a) of the third housing (203). For example, the electronic device (101) in the third state (101c) may be in a state where both ends of the display (160) arranged across the first housing (201), the second housing (202), and the third housing (203) are folded. For example, the electronic device (101) in the third state (101c) may be in a state where the first area arranged on the front of the first housing (201) is folded toward the second area arranged on the front of the second housing (202), and the third area arranged on the front of the third housing (203) is folded toward the second area.

For example, the conductive portion (220) can radiate an RF signal of a first frequency band.

[0074] According to one embodiment, the housing (200) may include an RF signal aperture (230). For example, the RF signal aperture (230) may be positioned near the conductive portion (220). For example, the RF signal aperture (230) may be positioned adjacent to the first side portion (201a) of the first housing (201).

[0075] According to one embodiment, a matching circuit (212) may be disposed on a printed circuit board (210). For example, the matching circuit (212) may be disposed in a peel-cut area (231) of the printed circuit board (210). The peel-cut area (231) may include an area where a portion of the metal layer of the printed circuit board (210) has been removed. For example, the peel-cut area (231) may be disposed adjacent to a conductive portion (220). For example, the peel-cut area (231) may be disposed such that at least a portion overlaps with an RF signal aperture (230).

[0076] According to one embodiment, the matching circuit (212) may include at least one of at least one capacitive element or at least one inductor. For example, the matching circuit (212) may be electrically connected to the conductive part (220) at a second point (222) of the conductive part (220). For example, the matching circuit (212) may be electrically connected to the conductive part (220) by a connecting member (211) (e.g., a c-clip) electrically connecting the second point (222) of the conductive part (220) to the printed circuit board (210). For example, the matching circuit (212) may change the impedance of the conductive part (220). For example, the matching circuit (212) may change the resonant frequency of the RF signal radiated through the conductive part (220).

[0077] According to one embodiment, the RF signal aperture (230) may be formed with a length along the first side portion (201a). For example, the RF signal aperture (230) may be formed such that both ends are adjacent to the second side portion (201b) and the third side portion (201c), respectively. For example, the RF signal aperture (230) may be formed to have a length corresponding to at least a portion of the conductive portion (220). For example, the RF signal aperture (230) may be formed to have a length corresponding to at least a portion of the first side portion (201a) included in the conductive portion (220).

[0078] According to one embodiment, a conductive member may be disposed inside the third housing (203). For example, at least a portion of the fourth side portion (203a) may be formed of a conductive member. For example, the conductive member may include a slot (240). For example, the slot (240) may be formed by a conductive member that forms at least a portion of the fourth side portion (203a) and at least a portion of a support member included in the third housing (203). For example, the slot (240) may be formed to have a length along the fourth side portion (203a). For example, the slot (240) may be formed to have a length corresponding to the length of the conductive portion (220). In one embodiment, the length of the slot (240) may be determined according to the resonant frequency of the antenna including the conductive portion (220). For example, the slot (240) may be formed to have a length corresponding to at least a portion of the length of the first side portion (201a) included in the conductive portion (220). For example, the slot (240) may be formed to have a length longer than about 1 / 4 times the length of the first wavelength corresponding to the first frequency band. For example, the slot (240) may be positioned at a location corresponding to the conductive portion (220). For example, the slot (240) may be filled with a non-conductive material.

[0079] According to one embodiment, the RF signal may include antenna resonance based on the length of the conductive portion (220) and structural resonance of the electronic device (101). For example, the RF signal may include a first resonance frequency due to antenna resonance. For example, the RF signal may include a second resonance frequency due to structural resonance. For example, the first resonance frequency may be included in a first frequency band. For example, the second resonance frequency may be adjusted according to the length of the slot (240). For example, the first resonance frequency and / or the second resonance frequency may be included in a first frequency band by the length of the slot (240) corresponding to a predetermined length.

[0080] The electronic device (101) in the third state (101c) may have more difficulty radiating an RF signal than the electronic device (101) in the first state (101a) because the first side portion (201a) and the fourth side portion (203a) are adjacent. A slot (240) formed adjacent to the fourth side portion (203a) can reduce the decrease in efficiency of the RF signal radiated by the electronic device (101) in the third state (101c).

FIG. 5 is a diagram for comparing and explaining the efficiency of an antenna according to the length (S) of a slot (240) of an electronic device (101) described with reference to FIG. 4. The width of the electronic device (101) may be about 73.5 mm. The antenna may radiate an RF signal through a conductive part (e.g., the conductive part (220) of FIG. 4). Referring to FIG. 5, the target frequency (501) of the antenna of an electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 4) may be about 0.8 GHz to about 0.95 GHz.

[0097] Referring to the first graph (510) to the fourth graph (540), it can be confirmed that the radiation efficiency of an antenna of an electronic device having a slot (e.g., slot (240) in FIG. 4) is higher than the radiation efficiency of an antenna of an electronic device not having a slot (e.g., slot (240) in FIG. 4). Additionally, it can be confirmed that the radiation efficiency of the antenna at the target frequency (501) increases as the length (S) of the slot (e.g., slot (240) in FIG. 4) increases.

[0098] Referring to FIG. 5, the fifth graph (550) shows the total efficiency of the antenna when the slot (e.g., the slot (240) of FIG. 4) is absent. The sixth graph (560) shows the total efficiency of the antenna when the length (S) of the slot (e.g., the slot (240) of FIG. 4) is approximately 12.5 mm.

The eighth graph (580) shows the total efficiency of the antenna when the length (S) of the slot (e.g., the slot (240) of FIG. 4) is approximately 72.5 mm.

[0099] Referring to the fifth graph (550) through the eighth graph (580), it can be confirmed that the RF signal radiated from the antenna includes a plurality of resonant frequencies. For example, the RF signal may include a first resonant frequency formed based on the length of the conductive part (220) and a second resonant frequency formed based on the structural resonance of the electronic device (e.g., the electronic device (101) of FIG. 4).

[0100] Referring to the fifth graph (550), when the slot (e.g., slot (240) of FIG. 4) is not present, the first resonant frequency (551) of the antenna may be approximately 0.93 GHz and the efficiency may be approximately -5 dB. When the slot (e.g., slot (240) of FIG. 4) is not present, the second resonant frequency (552) of the antenna may be approximately 1.3 GHz and the efficiency may be approximately -13.8 dB.

[0101] Referring to the 6th graph (560), when the length (S) of the slot (e.g., slot (240) in FIG. 4) is about 12.5 mm, the first resonant frequency (561) of the antenna is about 0.92 GHz and the efficiency is about -4.1 dB. When the length (S) of the slot (e.g., slot (240) in FIG. 4) is about 12.5 mm, the second resonant frequency (562) of the antenna is about 1.3 GHz and the efficiency is about -13.8 dB.

[0102] Referring to the 7th graph (570), when the length (S) of the slot (e.g., slot (240) in FIG. 4) is about 44 mm, the first resonant frequency (571) of the antenna is about 0.91 GHz and the efficiency may be -4.1 dB. When the length (S) of the slot (e.g., slot (240) in FIG. 4) is about 44 mm, the second resonant frequency (572) of the antenna is about 1.4 GHz and the efficiency may be about -10.8 dB.

[0103] Referring to graph 8 (580), when the length (S) of the slot (e.g., slot (240) in FIG. 4) is about 72.5 mm, the first resonant frequency (551) is about 0.89 GHz and the efficiency may be -3 dB. When the length (S) of the slot (e.g., slot (240) in FIG. 4) is about 72.5 mm, the second resonant frequency (582) of the antenna is about 1.04 GHz and the efficiency may be about -2.2 dB.

[0104] Referring to the 5th graph (550) through the 8th graph (580), it can be confirmed that as the length (S) of the slot (e.g., slot (240) in FIG. 4) increases, the first resonant frequency (551, 561, 571, 581) of the antenna shifts to a lower frequency. It can be confirmed that the total efficiency of the antenna of an electronic device having a slot (e.g., slot (240) in FIG. 4) is higher than the total efficiency of the antenna of an electronic device not having a slot (e.g., slot (240) in FIG. 4).

[0105] Referring to the 5th graph (550) through the 8th graph (580), it can be seen that the second resonant frequency (552, 562, 572, 582) of the antenna changes as the length (S) of the slot (e.g., slot (240) in FIG. 4) changes. It can be seen that the total efficiency of the antenna at the second resonant frequency (552, 562, 572, 582) changes as the length of the slot (e.g., slot (240) in FIG. 4) changes.

[0106] FIG. 6 is a diagram for comparing and explaining the S-parameters of an antenna of an electronic device according to the length of a slot according to one embodiment. FIG. 6 is a diagram for comparing and explaining the S-parameters (input-reflection coefficients) of an antenna according to the length (S) of a slot (e.g., slot (240) of FIG. 4) of an electronic device (101) described with reference to FIG. 4. The width of the electronic device (101) may be about 73.5 mm. The antenna may radiate an RF signal through a conductive part (e.g., conductive part (220) of FIG. 4). Referring to FIG. 6, the target frequency (601) of the antenna of an electronic device (e.g., electronic device (101) of FIG. 4) according to one embodiment may be about 0.8 GHz to about 0.95 GHz.

[0107] Referring to FIG. 6, the first graph (610) shows the input-reflection coefficient of the antenna when the slot (e.g., slot (240) in FIG. 4) is absent. The second graph (620) shows the input-reflection coefficient of the antenna when the length (S) of the slot (e.g., slot (240) in FIG. 4) is about 12.5 mm. The third graph (630) shows the input-reflection coefficient of the antenna when the length (S) of the slot (e.g., slot (240) in FIG. 4) is about 44 mm. The fourth graph (640) shows the input-reflection coefficient of the antenna when the length (S) of the slot (e.g., slot (240) in FIG. 4) is about 72.5 mm.

[0108] Referring to the fourth graph (640), it can be confirmed that the RF signal radiated from the antenna includes a plurality of resonant frequencies. For example, the RF signal may include a first resonant frequency formed based on the length of the conductive part (220) and a second resonant frequency formed based on the structural resonance of the electronic device (e.g., the electronic device (101) of FIG. 4).

[0109] Referring to the first graph (610), when the slot (e.g., slot (240) of FIG. 4) is not present, the first resonant frequency (611) of the antenna may be approximately 0.92 GHz, and the input-reflection coefficient may be approximately -4 dB. Referring to the second graph (620), when the length (S) of the slot (e.g., slot (240) of FIG. 4) is approximately 12.5 mm, the first resonant frequency (621) of the antenna may be approximately 0.91 GHz, and the input-reflection coefficient may be approximately -4 dB. Referring to the third graph (630), when the length (S) of the slot (e.g., slot (240) of FIG. 4) is approximately 44 mm, the first resonant frequency (631) of the antenna may be approximately 0.89 GHz, and the input-reflection coefficient may be approximately -4.3 dB. Referring to the fourth graph (640), when the length (S) of the slot (e.g., slot (240) in FIG. 4) is about 72.5 mm, the first resonant frequency (641) is about 0.87 GHz, and the input-reflection coefficient may be about -7 dB. When the length (S) of the slot (e.g., slot (240) in FIG. 4) is about 72.5 mm, the second resonant frequency (642) of the antenna is about 1.02 GHz, and the input-reflection coefficient may be about -8.5 dB.

[0110] Referring to the first graph (610) through the fourth graph (640), it can be seen that as the length (S) of the slot (e.g., slot (240) in FIG. 4) increases, the first resonant frequency (611, 621, 631, 641) of the antenna shifts to a lower frequency. It can be seen that the input-reflection coefficient of an electronic device having a slot (e.g., slot (240) in FIG. 4) is lower than the input-reflection coefficient of an electronic device not having a slot (e.g., slot (240) in FIG. 4). It can be seen that as the length (S) of the slot (e.g., slot (240) in FIG. 4) increases, the input-reflection coefficient at the first resonant frequency (611, 621, 631, 641) decreases.

[0111] Referring to FIGS. 5 and 6, the length of a slot (e.g., slot (240) in FIG. 4) may be determined to radiate an RF signal included in the target frequency (501, 601). The radiation efficiency of the antenna may be high when the length (S) of the slot (e.g., slot (240) in FIG. 4) corresponds to the length of the conductive part (e.g., conductive part (220) in FIG. 4). The radiation efficiency of the antenna may be high when the length (S) of the slot (e.g., slot (240) in FIG. 4) is greater than 1 / 4 times the wavelength corresponding to the target frequency (501, 601). For example, the length of the slot (e.g., slot (240) in FIG. 4) may be determined when the electronic device (e.g., electronic device (101) in FIG. 4) is designed and / or manufactured.

When the length (S) of the slot (e.g., slot (240) in FIG. 9) is about 44 mm, the second resonant frequency (1142) of the antenna is about 1.32 GHz, and the input-reflection coefficient may be about -8.2 dB.

[0164] Referring to the fourth graph (1140), when the length (S) of the slot (e.g., slot (240) in FIG. 9) is about 72.5 mm, the first resonant frequency (1141) of the antenna is about 0.77 GHz, and the input-reflection coefficient may be about -1 dB.

[0165] Referring to the first graph (1110) to the fourth graph (1140), it can be seen that as the length (S) of the slot (e.g., slot (240) in FIG. 9) increases, the first resonant frequency (1111, 1121, 1131, 1141) of the antenna shifts to a lower frequency. It can be seen that the input-reflection coefficient of an electronic device having a slot (e.g., slot (240) in FIG. 9) is lower than the input-reflection coefficient of an electronic device not having a slot (e.g., slot (240) in FIG. 9). It can be seen that as the length (S) of the slot (e.g., slot (240) in FIG. 9) increases, the input-reflection coefficient at the first resonant frequency (1111, 1121, 1131, 1141) decreases.

For example, the sixth side portion (203c) may extend from the other end of the fourth side portion (203a) toward the second housing (202).

[0316] According to one embodiment, the first housing (201) can be coupled with the second housing (202). For example, the first housing (201) can be rotatably coupled with the second housing (202) through a first hinge assembly (204). For example, the front of the first housing (201) can be rotated toward the front of the second housing (202). The third housing (203) can be coupled with the second housing (202). For example, the third housing (203) can be rotatably coupled with the second housing (202) through a second hinge assembly (205). For example, the front of the third housing (203) can be rotated toward the front of the second housing (202).

[0317] For example, by rotating the first housing (201) and the third housing (203) toward the second housing (202), the front of the first housing (201) and the front of the third housing (203) can face the front of the second housing (202). For example, when the front of the first housing (201) and the front of the third housing (203) face the front of the second housing (202), the first housing (201) and the third housing (203) can be adjacent on the second housing (202). For example, the first side portion (201a) of the first housing (201) and the fourth side portion (203a) of the third housing (203) can be adjacent.

[0318] According to one embodiment, components of an electronic device (101) may be placed in the housing (200). For example, a display (160) may be placed on the front of the housing (200). For example, the display (160) may be placed across the first housing (201), the second housing (202), and the third housing (203). For example, the display (160) may include a first area placed on the front of the first housing (201), a second area placed on the front of the second housing (202), and a third area placed on the front of the third housing. For example, the first area of ​​the display (160) may be folded toward the second area. For example, the third area of ​​the display (160) may be folded toward the second area.

For example, the conductive portion (220) may include at least a portion of the first side portion (201a) of the first housing (201). For example, the conductive portion (220) may form at least a portion of the first side portion (201a) and at least a portion of the second side portion (201b). For example, the conductive portion (220) may be positioned so as to be spaced apart from one end and / or the other end of the first side portion (201a). For example, the conductive portion (220) may operate as a radiator of an antenna. For example, the conductive portion (220) may radiate an RF signal.

[0320] According to one embodiment, the housing (200) may provide a space and a support member in which internal components of the electronic device (101) can be seated. The support member may fix and support the components seated in the internal space of the housing (200).

[0321] According to one embodiment, the electronic device (101) may change state by rotation of the first housing (201) and / or the third housing (203). For example, the electronic device (101) may be in one of a first state (101a), a second state (e.g., the second state (101b) of FIG. 2) and a third state (101c).

[0322] For example, the electronic device (101) in the first state (101a) may have the housing (200) in an unfolded state. For example, the first state (101a) of the electronic device (101) may correspond to the first state described with reference to FIG. 2 and FIG. 3 (e.g., the first state (101a) of FIG. 2 or the first state (101a) of FIG. 3). For example, the electronic device (101) in the first state (101a) may have the first housing (201) and the third housing (203) unfolded from the second housing (202). For example, the electronic device (101) in the first state (101a) may have the front of the first housing (201) rotated so that it moves away from the front of the second housing (202), and the front of the third housing (203) rotated so that it moves away from the front of the second housing (202). For example, the electronic device (101) of the first state (101a) may be in an unfolded state, with a display (160) arranged across the first housing (201), the second housing (202), and the third housing (203).

[0323] For example, the electronic device (101) in the third state (101c) may be in a state where the front of the first housing (201) and the front of the third housing (203) are rotated so that they are close to the front of the second housing (202). For example, the third state (101c) of the electronic device (101) may correspond to the third state described with reference to FIG. 2 and FIG. 3 (e.g., the third state (101c) of FIG. 2 or the third state (101c) of FIG. 3). For example, the electronic device (101) in the third state (101c) may be in a state where the front of the first housing (201) and the front of the third housing (203) are adjacent to the front of the second housing (202). For example, the electronic device (101) in the third state (101c) may be in a state where the front of the first housing (201) and the front of the third housing (203) face the front of the second housing (202). For example, the electronic device (101) in the third state (101c) may be in a state where the first side portion (201a) of the first housing (201) is adjacent to the fourth side portion (203a) of the third housing (203). For example, the electronic device (101) in the third state (101c) may be in a state where both ends of the display (160) arranged across the first housing (201), the second housing (202), and the third housing (203) are folded. For example, the electronic device (101) of the third state (101c) may be in a state where a first region placed on the front of the first housing (201) is folded toward a second region placed on the front of the second housing (202), and a third region placed on the front of the third housing (203) is folded toward the second region.

[0324] According to one embodiment, a printed circuit board (210) may be disposed inside the housing (200). For example, a power supply unit (213) may be disposed on the printed circuit board (210). For example, the power supply unit (213) may include a wireless communication circuit. For example, the power supply unit (213) may be electrically connected to the conductive part (220) at a first point (221) of the conductive part (220). For example, the power supply unit (213) may be electrically connected to the conductive part (220) by electrically connecting the first point (221) of the conductive part (220) and the printed circuit board (210) with a connecting member (211) (e.g., a c-clip).

[0325] According to one embodiment, the conductive portion (220) can operate as an antenna radiator. For example, the conductive portion (220) can radiate an RF signal based on a feed signal provided from the feed portion (213). For example, the conductive portion (220) can radiate an RF signal of a first frequency band.

[0326] According to one embodiment, the first housing (201) may include an RF signal aperture (230). For example, the RF signal aperture (230) may be positioned near the conductive portion (220). For example, the RF signal aperture (230) may be positioned adjacent to the first side portion (201a) of the first housing (201). For example, both ends of the RF signal aperture (230) may be adjacent to the second side portion (201b) and the third side portion (201c), respectively. For example, the length of the RF signal aperture (230) may be formed along the first side portion (201a).

[0327] According to one embodiment, a matching circuit (212) may be disposed on the printed circuit board (210). For example, the matching circuit (212) may be disposed in a fill-cut area of ​​the printed circuit board (210). For example, the fill-cut area may be disposed such that at least a portion overlaps with the RF signal aperture (230). The fill-cut area may include an area where a portion of the metal layer of the printed circuit board (210) has been removed. For example, the fill-cut area may be disposed adjacent to the conductive portion (220). For example, the fill-cut area may be disposed adjacent to the first side portion (201a) of the first housing (201).

[0328] According to one embodiment, the matching circuit (212) may include at least one of at least one capacitive element or at least one inductor. For example, the matching circuit (212) may be electrically connected to the conductive part (220) at a second point (222) of the conductive part (220). For example, the matching circuit (212) may be electrically connected to the conductive part (220) by a connecting member (211) (e.g., a c-clip) electrically connecting the second point (222) of the conductive part (220) to the printed circuit board (210). For example, the matching circuit (212) may change the impedance of the conductive part (220). For example, the matching circuit (212) may change the resonant frequency of the RF signal radiated through the conductive part (220).

[0329] According to one embodiment, the peel-cut region may be formed with a length along the first side portion (201a). For example, the peel-cut region may be formed such that both ends are adjacent to the second side portion (201b) and the third side portion (201c), respectively. For example, the peel-cut region may be formed to have a length corresponding to at least a portion of the conductive portion (220). For example, the peel-cut region may be formed to have a length corresponding to the conductive portion (220) included in the first side portion (201a).

[0330] According to one embodiment, a conductive member may be disposed inside the third housing (203). For example, at least a portion of the conductive member may be disposed adjacent to the fourth side portion (203a) of the third housing (203). For example, the conductive member may include a slot (240). For example, the slot (240) may be formed to have a length along the fourth side portion (203a). For example, the slot (240) may be formed to have a length corresponding to the length of the conductive portion (220). For example, the slot (240) may be formed to have a length corresponding to the length of at least a portion of the first side portion (201a) included in the conductive portion (220). For example, the slot (240) may be formed to have a length longer than about 1 / 4 times the length of the first wavelength corresponding to the first frequency band. For example, the slot (240) may be disposed at a position corresponding to the conductive portion (220). For example, the slot (240) can be filled with a non-conductive material.

[0331] According to one embodiment, the RF signal may include a plurality of resonant frequencies. For example, the RF signal may include a first resonant frequency formed based on the length of the conductive portion (220) and a second resonant frequency formed based on the structural resonance of the electronic device (101). For example, the first resonant frequency may be included in a first frequency band.

[0332] According to one embodiment, the resonant frequencies (e.g., a first resonant frequency and a second resonant frequency) can be adjusted according to the length of the slot (240). For example, as the length of the slot (240) corresponds to a predetermined length, the first resonant frequency and / or the second resonant frequency may be included in a first frequency band.

[0333] The electronic device (101) in the third state (101c) may have more difficulty radiating an RF signal than the electronic device (101) in the first state (101a) because the first side portion (201a) and the fourth side portion (203a) are adjacent. A slot (240) formed adjacent to the fourth side portion (203a) can reduce the decrease in efficiency of the RF signal radiated by the electronic device (101) in the third state (101c).

[0334] The electronic device (101) of FIG. 24 may be inferred from the electronic device (101) described with reference to FIG. 2 to FIG. 23. Duplicate content is omitted.

[0338] According to one embodiment, the first housing (201) can be rotated toward the second housing (202). For example, the front of the first housing (201) can be rotated toward the front of the first part (202a) of the second housing (202). For example, by rotating the first housing (201) toward the second housing (202), the front of the first housing (201) can face the front of the first part (202a) of the second housing (202).

[0339] According to one embodiment, the third housing (203) can be rotated toward the second housing (202).

For example, by rotating the third housing (20b) toward the second housing (202), the front of the third housing (203) can face the front of the second part (202b) of the second housing (202).

[0340] According to one embodiment, the second housing (202) can be folded. For example, the second housing (202) can be folded by rotating the first part (202a) of the second housing (202) toward the second part (202b). For example, by rotating the first part (202a) toward the second part (202b), the rear side of the first part (202a) can face the rear side of the second part (202b).

[0341] According to one embodiment, the housing (200) may accommodate components of the electronic device (101). For example, the housing (200) may accommodate a first display (209a) and / or a second display (209b). For example, the first display (209a) may be positioned across the front of the first housing (201), the front of the second housing (202), and the front of the third housing (203). For example, the second display (209b) may be positioned on the rear of the second housing (202). For example, the second display (209b) may be positioned across the rear of the first part (202a) and the rear of the second part (202b) of the second housing (202).

[0342] According to one embodiment, the housing (200) may include a conductive portion (220). For example, the conductive portion (220) may operate as a radiator of an antenna. For example, the conductive portion (220) may radiate an RF signal.

[0343] According to one embodiment, the housing (200) may include a slot (240). For example, the slot (240) may be positioned adjacent to a side portion of the third housing (203) (for example, a fourth side portion (203a) of FIG. 2). For example, the slot (240) may be positioned at a location corresponding to a conductive portion (220). For example, the slot (240) may be formed to have a length corresponding to the length of the conductive portion (220). For example, the slot (240) may be filled with a non-conductive material.

[0344] According to one embodiment, the housing (200) may provide a space and a support member in which internal components of the electronic device (101) can be seated. For example, a printed circuit board (e.g., the printed circuit board (210) of FIG. 2) may be placed inside the housing (200).

[0345] According to one embodiment, the electronic device (101) may change state by rotation of the first housing (201), the third housing (203), the first part (202a) of the second housing (202) and / or the second part (202b) of the second housing (202). For example, the electronic device (101) may be in one of a first state (101a), a second state (e.g., the second state (101b) of FIG. 2), a third state (101c), and a fourth state (101d).

[0346] For example, the electronic device (101) in the first state (101a) may have the housing (200) in an unfolded state. For example, the electronic device (101) in the first state (101a) may have the display (160) placed across the first housing (201), the second housing (202), or the third housing (203) in an unfolded state. For example, the electronic device (101) in the first state (101a) may have the first housing (201) and the third housing (203) unfolded from the second housing (202), and the first part (202a) and the second part (202b) of the second housing (202) in an unfolded state. For example, the electronic device (101) in the first state (101a) may be in a state where the front of the first housing (201) is rotated so that it is away from the front of the second housing (202), the front of the third housing (203) is rotated so that it is away from the front of the second housing (202), and the rear of the first part (202a) and the rear of the second part (202b) of the second housing (202) are rotated so that they are away from each other.

[0347] For example, the electronic device (101) in the second state (for example, the second state (101b) of FIG. 2) may be in a state where the front of one of the first housing (201) or the third housing (203) is rotated so that it is close to the front of the second housing (202), and the front of the other housing is rotated so that it is far from the front of the second housing (202). For example, the electronic device in the second state (for example, the second state (101b) of FIG. 2) may be in a state where the front of the first housing (201) faces the front of the second housing (202), and the front of the third housing (203) faces the same direction as the front of the second housing (202). For example, the electronic device of the second state (for example, the second state (101b) of FIG. 2) may be in a state where the front of the third housing (203) faces the front of the second housing (202), and the front of the first housing (201) faces the same direction as the front of the second housing (202).

[0348] For example, the electronic device (101) in the third state (101c) may be in a state where the front of the first housing (201) and the front of the third housing (203) are rotated so that they are close to the front of the second housing (202). For example, the electronic device (101) in the third state (101c) may be in a state where the front of the first housing (201) and the front of the third housing (203) are adjacent to the front of the second housing (202). For example, the electronic device (101) in the third state (101c) may be in a state where the front of the first housing (201) and the front of the third housing (203) face the front of the second housing (202). For example, the electronic device (101) in the third state (101c) may have both ends of the display (160) placed across the first housing (201), the second housing (202), or the third housing (203) folded. For example, the electronic device (101) in the third state (101c) may have a first area placed on the front of the first housing (201) folded toward a second area placed on the front of the second housing (202), and a third area placed on the front of the third housing (203) folded toward the second area. When the electronic device (101) is in the third state (101c), the first housing (201) and the third housing (203) may be adjacent on the second housing (202).

[0349] For example, the electronic device (101) in the fourth state (101d) may be in a state where the electronic device (101) is rotated so that the rear surface of the first part (202a) of the second housing (202) is close to the rear surface of the second part (202b) in the third state (101c). For example, the electronic device (101) in the fourth state (101d) may be in a state where the second display (209b) placed across the first part (202a) and the second part (202b) of the second housing (202) is folded in the third state (101c).

[0351] According to the disclosed embodiments, an electronic device (e.g., the electronic device (101) of FIG. 3) can secure a specified performance of the antenna at a target frequency regardless of the shape of the conductive part used as an antenna radiator by having a slot (e.g., the slot (240) of FIG. 3) arranged therein. Additionally, the resonant frequency of the antenna (e.g., the resonant frequency of the antenna radiator and the structural resonant frequency) can be shifted according to the length of the slot (e.g., the slot (240) of FIG. 3).

[0352] An electronic device according to one disclosed embodiment (e.g., the electronic device (101) of FIG. 3) may include a slot (e.g., the slot (240) of FIG. 3) formed such that the resonant frequency of the antenna is included in the target frequency.
