Description
Electronic device including an antenna
[0001] Embodiments of the present disclosure relate to an electronic device including an antenna.
[0002] A foldable electronic device may include a first housing and a second housing rotatably connected to the first housing via a hinge device. At least a portion of a metal frame (e.g., a metal bezel) disposed on a side of the first housing and / or the second housing may be used as an antenna. The antenna may be designed so that its radiation performance is not degraded as the electronic device folds and unfolds.
[0003] An electronic device may include a foldable electronic device comprising a first housing and a second housing foldably connected to the first housing via a hinge device. The electronic device may include a flexible display that is used in an unfolded state and is arranged to receive support from at least a portion of the second housing via the hinge device from the first housing. The foldable electronic device may include at least one antenna (e.g., a metal frame antenna) that is arranged in an interior space of at least one of the housings or uses at least a portion of a conductive side. The volume and number of such antennas provided by the electronic device may be determined according to a frequency, bandwidth, and / or type for each service.
[0004] Foldable electronic devices may utilize a metal frame to reinforce rigidity, and when folded, the metal frames of the first housing and the second housing may form a "U" shape. However, planar parasitic resonance may occur through the conductive sheet (e.g., Cu sheet) of the flexible display disposed therein.

[0141] Referring to FIGS. 5A to 8B , the electronic device (300) may include the electronic device (300) described above with reference to FIGS. 2A to 4 , or may be similar in many aspects thereto. Accordingly, a repeated description of the electronic device (300) described above with reference to FIGS. 2A to 4 may be omitted for brevity.
[0142] Referring to FIG. 5A, the electronic device (300) can be folded so that one side of the first housing (310) (e.g., the first side (311) of FIG. 2A) and one side of the second housing (320) (e.g., the second side (312) of FIG. 2A) face each other with the hinge structure (340) as the central axis. When one side (e.g., first side (311)) of the first housing (310) and one side (e.g., second side (312)) of the second (320) are folded to face each other with the hinge structure (340) as the central axis in the electronic device (10), the first housing (310), the hinge structure (340), and the second housing (320) can be electrically connected, and the first housing (310) and the second housing (320) can be adjacent to each other, so that electromagnetic coupling can occur between the first housing (310) and the second housing (320).
[0143] Referring to FIGS. 5B and 7A, the first housing (310), the hinge structure (340), and the second housing (320) of the folded electronic device (300) can be equivalentized in the form of a shielded parallel plate. For example, the electronic device (300) equivalentized in the form of a shielded parallel plate can be referred to as a shielded parallel plate model (300). Hereinafter, the first housing (310) can be referred to as a first substrate (plate), and the second housing (320) can be referred to as a second substrate.
[0144] Referring to FIGS. 6A, 6B, and 7B, the electric field (E-Field) of the electronic device (300) in the folded state is proportional to the potential, so the potential is zero (0) at the hinge (340) where the first substrate (310) and the second substrate (320) are grounded, and thus the magnitude of the electric field may be zero (0). On the other hand, in the electronic device (300) that may be in the folded state, the potential may increase as it moves away from the hinge (340), and thus the magnitude of the electric field may also increase.
[0145] Referring to FIGS. 8A and 8B, in the shielded parallel plate model (300), a first surface current (J1) can be formed on the surfaces of the first substrate (310), the hinge (340), and the second substrate (320). The first surface current (J1) can circulate through the first substrate (310), the hinge (340), and the second substrate (320). For example, the first surface current (J1) may be formed in the form of a current that circulates from one side of the second substrate (320) (e.g., the fourth side (323a) of the second housing (320)) to the hinge (340), from the hinge (340) to one side of the first substrate (310) (e.g., the first side (313a) of the first housing (310)), and then to one side of the second substrate (320) (e.g., the fourth side (323a) of the second housing (320)). For another example, the direction of the surface current induced in the first substrate (310) and the direction of the surface current induced in the second substrate (320) may be opposite to each other.

FIG. 9B is a graph (1110) illustrating a reflection coefficient (S1,1) (1111) of a resonant frequency formed in an electronic device (300-1) in a folded state that does not include a conductive portion on a side according to various embodiments. FIG. 9C is a conceptual diagram illustrating a mode of an electric field of a second housing (320) of an electronic device (300-1) in a folded state that does not include a conductive portion on a side according to various embodiments, using a shielded parallel plate model.
[0147] Referring to FIG. 9a, a shielded parallel plate model corresponding to an electronic device (300-1) in a folded state that does not include a conductive portion on the side may be identical to or similar to the shielded parallel plate model (300) of FIG. 5b or the shielded parallel plate model (300) of FIG. 8a.
[0148] Referring to FIG. 9b, the first parasitic resonant frequency (1) formed in the folded electronic device (300-1) that does not include a conductive portion on the side can be operated at about 888.1253 MHz. (Example: 1111 graph)
[0149] Referring to FIG. 9c, the mode of the electric field illustrated in the shielded parallel plate model corresponding to the folded electronic device (300-1) that does not include a conductive portion on the side is as shown in FIGS. 6a and 6b, since the electric field (E-Field) of the folded electronic device (300-1) is proportional to the potential, the potential is zero (0) at the hinge (340) where the first substrate (310) and the second substrate (320) are grounded, and thus the magnitude of the electric field may be zero (0). On the other hand, since the potential may increase as the distance from the hinge (340) in the folded electronic device (300-1) increases, the magnitude of the electric field may also increase. An electromagnetic field (e.g., a first parasitic resonance) may be generated by the first surface current (J1) formed on the surface of the folded electronic device (300-1). The mode of the electric field of the electronic device (300-1) due to the first parasitic resonance may be referred to as the first mode.

[0151] Referring to FIG. 10A, the first substrate (310) may include a first side member (313) including conductive side portions. For example, the first side member (313) may include a first side portion (313a), a first edge portion (313d) disposed between the first side portion (313a) and a third side portion (313c), and a second edge portion (313e) disposed between the first side portion (313a) and the second side portion (313b). At least one of the first side portion (313a), the second side portion (313b), the third side portion (313c), the first edge portion (313d), and the second edge portion (313e) may be formed of a conductive material.

At least one of the fourth side portion (323a), the fifth side portion (323b), the sixth side portion (323c), the third edge portion (323d), and the fourth edge portion (323e) can be formed of a conductive material. The fourth side portion (323a) may include a first segment (3261) and a second segment (3262) formed of a non-conductive material. The fifth side portion (323b) may include a third segment (3263) and a fourth segment (3264). The sixth conductive side portion (323c) may include a fifth segment (3265) and a sixth segment (3266).
[0153] Referring to FIG. 10b, it can be seen that the resonant frequency (1) formed in the folded electronic device (300) including a plurality of side portions (e.g., a first side portion (313a), a second side portion (313b), a third side portion (313c), a fourth side portion (323a), a fifth side portion (323b), and a sixth side portion (323c)) is 872 MHz, which is a downward shift compared to the resonant frequency described with reference to FIG. 9b (e.g., graph 1121).

For example, the mode of the electric field of the second substrate (320) may be substantially the same as and / or similar to the first mode, which is the mode of the electric field shown in the second substrate (320) of the shielded parallel plate model (300) described with reference to FIG. 9c, where the fourth side portion (323a), the fifth side portion (323b), the sixth side portion (323c), the third edge portion (323d), and the fourth edge portion (323e) may not be electrically connected to the ground.
[0155] FIG. 11A is a conceptual diagram illustrating a shielded parallel plate model corresponding to an electronic device (300) in a folded state in which a plurality of side portions (313a to 323c) formed of a conductive material are grounded, according to various embodiments. FIG. 11B is a graph (1130) illustrating a reflection coefficient (S1,1) (1131) of a resonant frequency formed in an electronic device (300) in a folded state in which a plurality of side portions (313a to 323c) formed of a conductive material are grounded, according to various embodiments.

The second side (313b) may be electrically connected to the ground (414) of the first substrate (310). The third side (313c) may be electrically connected to the ground (412) of the first substrate (310). The second edge (313e) may be electrically connected to the ground (413) of the first substrate (310).
[0157] Referring to Fig. 11b, when the plurality of side portions (313a to 323c) are grounded, the resonant frequency (1) formed in the electronic device (300) in the folded state may operate at approximately 840 MHz, which may be lower than the resonant frequencies described with reference to Figs. 9b and 10b. For example, the position of the resonant frequency (1) of Fig. 11b on the graph may shift downward compared to the position of the resonant frequency (1) of Fig. 9b and the position of the resonant frequency (1) of Fig. 10b. This may mean that in the foldable electronic device (300), when in the folded state, the operating frequency band may be affected by the grounding of the plurality of side portions (313a to 323c).
[0158] Referring to FIG. 11c, the fourth side portion (323a), the fifth side portion (323b), the sixth side portion (323c), the third corner portion (323d), and the fourth corner portion (323e) formed of a conductive material may be electrically connected to the ground of the second substrate (320).

[0160] Referring to FIG. 12a, a surface current formed on the surface of the second substrate (320) based on the XY plane may be formed in a form that flows from the hinge (340) to one side of the second substrate (320) (e.g., the fourth side portion (313a) of the second housing (320)). The direction of the surface current induced on the surface at the cavity parasitic resonance frequency in each of the fourth side portion (313a), the fifth side portion (323b), the sixth side portion (323c), the third corner portion (323d), and the fourth corner portion (323e) may be substantially the same as and / or similar to the direction of the surface current formed on the surface of the second substrate (320).
[0161] Referring to FIG. 12b, the direction of the second surface current (J2) induced on the surface at the cavity parasitic resonance frequency in the sixth side portion (323c) may be substantially the same as and / or similar to the direction of the first surface current (J1) formed on the surface of the second substrate (320).

FIG. 13B is a conceptual diagram illustrating the surface current of the second housing (320) and the surface current of the sixth side portion (323c) of an electronic device (300) according to various embodiments, in a shielded parallel plate model.
[0163] Referring to Fig. 13a, in the shielded parallel plate model, the sixth side portion (323c) may be grounded to the second substrate (320) via the grounding member (420). A second parasitic resonance having a frequency whose wavelength is approximately λ / 4 may be generated at the sixth side portion (323c) grounded to the second substrate (320) via the grounding member (420). The mode of the electric field due to the second parasitic resonance formed at the grounded sixth side portion (323c) may be referred to as the second mode.

In the case where the sixth side portion (323c) of the folded electronic device (300) is electrically connected to the ground of the second substrate (320), the electronic device (300) may generate an electric field corresponding to a first mode by a first surface current (J1) induced on the surface of the second substrate (320) and an electric field corresponding to a second mode by a second parasitic resonance formed by a second surface current (J2) induced in the sixth side portion (323c) electrically connected to the ground of the second substrate (320). In other words, electric fields of different first modes and electric fields of different second modes may be generated in the electronic device (300). For example, the frequency of the first parasitic resonance may be referred to as a cavity resonance frequency or a PPW (parallel plate waveguide) resonance frequency. The frequency of the second parasitic resonance may be referred to as a line resonance frequency.

[0169] Referring to FIG. 14d, the mode of the electric field illustrated in the shielded parallel plate model corresponding to the folded electronic device (300) that does not include side portions or in which the side portions are not formed of a conductive material is as shown in FIGS. 6a to 6b and FIG. 9c, the electric field (E-Field) of the folded electronic device (300) is proportional to the potential, so that the potential is zero (0) at the hinge (340) where the first substrate (310) and the second substrate (320) are grounded, and thus the magnitude of the electric field may be zero (0). On the other hand, the magnitude of the electric field may also increase as the potential increases further from the hinge (340) in the folded electronic device (300). A first parasitic resonance may be generated by a first surface current (J1) formed on the surface of the folded electronic device (300).

[0173] Referring to FIG. 15c, a first parasitic resonance (existing PPW resonance (2)) formed by a first surface current (J1) of a second housing (320) may be formed in the electronic device (300) in a folded state. In the electronic device (300) in a folded state, the first parasitic resonance (existing PPW resonance (2)) may be formed by a second parasitic resonance (Line resonance (1)) by a second surface current (J2) induced in the sixth side (323c) that is grounded to the second substrate (320) through the connecting member (420).

[0177] FIG. 16A is a conceptual diagram illustrating a current distribution of an electronic device (300) in which a first parasitic resonance and a second parasitic resonance are formed, according to various embodiments, in a shielded parallel plate model. FIG. 16B is a conceptual diagram illustrating a current distribution of an electronic device (300) in which a first parasitic resonance and a second parasitic resonance are formed, according to various embodiments, in a shielded parallel plate model.
[0178] Referring to FIGS. 16A and 16B, the direction of the second surface current (J2) induced in the grounded sixth side portion (323c) of the second substrate (320) through the connecting member (420) may be formed in the opposite direction to the direction of the second surface current (J2) induced in the surface of the second substrate (320) due to the grounding. For example, in a shielded parallel plate model corresponding to the electronic device (300), the second surface current (J1) formed on the surface of the second substrate (320) may be formed in the -Y-axis direction with respect to the XY plane. In the shielded parallel plate model, the second surface current (J2) induced in the grounded sixth side portion (323c) of the second substrate (320) through the connecting member (420) may be formed in the +Y-axis direction, which is the opposite direction to the direction of the surface current (J1).
[0179] In the shielded parallel plate model, the second surface current (J2) induced in the ground and the grounded sixth side portion (323c) of the second substrate (320) through the connecting member (420) is formed in a direction opposite to the direction of the surface current (J1) induced in the surface of the second substrate (320), so that a resonance split phenomenon may occur between the frequency of the first parasitic resonance due to the first surface current (J1) formed in the surface of the second substrate (320) in the shielded parallel plate model and the frequency of the second parasitic resonance due to the second surface current (J2) induced in the ground and the grounded sixth side portion (323c) of the second substrate (320) through the connecting member (420). For example, the resonance splitting phenomenon may mean a phenomenon in which the frequency of the first parasitic resonance formed by the first surface current (J1) formed on the surface of the second substrate (320) is affected by the second parasitic resonance formed by the second surface current (J2) induced in the sixth side portion (323c) grounded with the second substrate (320), and thus cannot maintain the existing frequency band and shifts to a specific frequency band, as illustrated in FIG. 15c.

FIG. 17b is a conceptual diagram illustrating the current distribution of an electronic device (300) in which a first parasitic resonance is formed, according to various embodiments, in a shielded parallel plate model.
[0181] Referring to FIGS. 17a and 17b, the direction of the second surface current (J2) induced in the sixth side portion (323c) that is not grounded to the ground of the second substrate (320) may be formed in the same direction as the direction of the second surface current (J2) induced in the surface of the second substrate (320), so that it may be different from the direction of the second surface current (J2) induced in the sixth side portion (323c) that is grounded to the ground of the second substrate (320) through the connecting member (420) illustrated in FIGS. 16a and 16b. For example, when the sixth side portion (323c) is not grounded to the ground of the second substrate (320), the resonance splitting phenomenon may not occur.

For example, the fourth side portion (323a) may be arranged in the Y-axis direction of the second housing (320) with respect to the XY plane. For example, the fourth side portion (323a) may be arranged to face the hinge structure (340) with respect to the X-axis in the second housing (320). For example, the fourth side portion (323a) may include a first segment portion (3261) and a second segment portion (3262) formed of a non-conductive material.
[0184] The second side (323b) may be arranged in the -X-axis direction of the second housing (320) with respect to the XY plane. The fifth side portion (323b) may include a third segment (3263) and a fourth segment (3264) formed of a non-conductive material. For example, the fifth side portion (323b) may be electrically separated from the hinge structure (340) through the third segment (3263).
[0185] The sixth side portion (323c) may be arranged in the +X-axis direction of the second housing (320) with respect to the XY plane. For example, the sixth side portion (323c) may be arranged symmetrically with respect to the fifth side portion (323b) with respect to the Y-axis in the second housing (320). The sixth side portion (323c) may include a fifth segment (3265) and a sixth segment (3266) formed of a non-conductive material. For example, the sixth side portion (323c) may be electrically separated from the hinge structure (340) through the sixth segment (3266).
[0186] The third edge portion (323d) may be disposed between the fourth side portion (323a) and the sixth side portion (323c). The third edge portion (323d) may be electrically isolated from the fourth side portion (323a) through the second segment (3262).

The fourth edge portion (323e) may be electrically isolated from the fourth side portion (323a) through the first segment (3261). The fourth edge portion (323e) may be electrically isolated from the fifth side portion (323b) through the fourth segment (3264).

[0188] Referring to FIG. 19A, in one embodiment, a fourth side portion (323a) of a second housing (320) of an electronic device (300) may be grounded to a second support member (3231) via a first ground portion (421). For example, the first ground member (421) may electrically connect the fourth side portion (323a) and the second support member (3231). For example, the first ground member (421) may electrically connect the fourth side portion (323a) and the second support member (3231) via a printed circuit board (e.g., the second board assembly (362)).
[0189] The electronic device (300) may include a wireless communication circuit (600). The fourth side portion (323a) may be electrically connected to the wireless communication circuit (600). In one embodiment, the fourth side portion (323a) may be electrically connected to the third corner portion (323d) via a first connection portion (821) including a first switch (821a) and a first conductive line (821b). One end of the first connection portion (821) may be electrically connected to the fourth side portion (323a). The other end of the first connection portion (821) may be electrically connected to the third corner portion (323d). For example, the first connection portion (821) may be a logical connection as a connection line for connecting the fourth side portion (323a) and the third corner portion (323d). For example, the first switch (821a) and the first conductive line (821b) may be formed on a printed circuit board (e.g., the second board assembly (362)). For another example, the fourth side portion (323a) and the third corner portion (323d) may operate as a radiator (720). For another example, the fourth side portion (323a) may operate as a radiator (720) together with the third corner portion (323d) through the first switch (821a). For example, the fourth side portion (323a) may operate as a radiator solely through the first switch (821a).
[0190] In one embodiment, the sixth side portion (323c) may be grounded to the second support member (3231) via a first matching circuit portion (921). For example, the first matching circuit portion (921) may include a second switch (922a) and at least one first inductor (921b). For another example, the first matching circuit portion (921) may electrically connect the sixth side portion (323c) and the second support member (3231). For yet another example, the first matching circuit portion (921) may electrically connect the sixth side portion (323c) and the second support member (3231) via a printed circuit board (e.g., the second board assembly (362)). For example, one end of the first matching circuit portion (921) may be electrically connected to the sixth side portion (323c). The other end of the second grounding portion (422) may be electrically connected to the second support member (3231). A second parasitic resonance (521) may be formed in the first matching circuit portion (921) and the sixth side portion (323c).
[0191] In one embodiment, the first matching circuit (921) may be a tunable matching circuit including a plurality of inductors having various inductance values. For example, the number of first inductors (921b) included in the first matching circuit (921) may be plural (e.g., a positive integer greater than 1). For example, the plurality of first inductors (921b) may be connected in parallel with the second switch (921a). The second switch (921a) may be selectively connected to one of the plurality of first inductors (921b). For example, the inductance value of the first matching circuit (921) may be determined based on the frequency of a transmission signal of the electronic device (300). For another example, the inductance value of the first matching circuit (921) may be sufficiently large to operate close to open at the frequency of the transmission signal of the electronic device (300). For example, the inductance value of the first matching circuit (921) may be set to exceed a predetermined threshold value so that the sixth side portion (323c) is not electromagnetically coupled with the radiator (720). In other words, the electronic device (300) can control the second parasitic resonant frequency (521) while minimizing the influence on the radiator (720) through the first matching circuit (921). For example, the inductance value of the first matching circuit (921) may have various values, such as, but not limited to, about 39 nH, about 56 nH, or about 100 nH.
[0192] FIG. 19b is a conceptual diagram illustrating the distribution of surface current of an electronic device (300) in a wireless communication system according to various embodiments.
[0193] Referring to FIG. 19b, in the folded electronic device (300), the current distribution formed on the surface of the second housing (320) may be formed to face the fourth side portion (323a) from the hinge structure (340). For example, in the electronic device (300), the current distribution formed on the surface of the second housing (320) may be formed to face the ground point of the fourth side portion (323a) electrically connected to the second support member (3231) from the hinge structure (340). For example, in the electronic device (300), the current distribution formed on the surface of the second housing (320) may be formed to face the ground point connected to the fourth side portion (323a) and the first ground member (421) from the hinge structure (340).
[0194] The electric field distribution of the sixth side portion (323c) and a portion (a) of the second housing (320) adjacent to the sixth side portion (323c) in the electronic device (300) may be the same as the electric field distribution described with reference to FIGS. 19c and 19d, or may be similar in various aspects.
[0195] FIG. 19c is a conceptual diagram illustrating the distribution of surface current on one side of an electronic device (300) according to various embodiments.
[0196] FIG. 19d is a conceptual diagram illustrating the distribution of surface current on one side of an electronic device (300) according to various embodiments.
[0197] Referring to FIGS. 19c and 19d, the direction of the second surface current (J2) induced in the second support member (3231) and the grounded sixth side portion (323c) through the first matching circuit portion (921) may be formed in a direction opposite to the direction of the second surface current (J2) induced in the surface of the second housing (320) (e.g., the second rear cover (234)) due to the grounding. For example, in the electronic device (300), the first surface current (J1) formed on the surface of the second housing (320) may be formed in the -Y axis direction based on the XY plane. A second surface current (J2) induced in the second housing (320) of the electronic device (300) to the second support member (3231) and the grounded sixth side portion (323c) through the first matching circuit portion (921) can be formed in the +Y-axis direction, which is opposite to the direction of the first surface current (J1).
[0198] Since the second surface current (J2) induced in the second support member (3231) and the grounded sixth side portion (323c) through the first matching circuit portion (921) in the electronic device (300) is formed in a direction opposite to the direction of the first surface current (J1) induced in the surface of the second housing (320), a resonance split phenomenon may occur between the frequency of the first parasitic resonance due to the first surface current (J1) formed in the surface of the second housing (320) in the electronic device (300) and the frequency (521) of the second parasitic resonance due to the second surface current (J2) induced in the second support member (3231) of the second housing (320) and the grounded sixth side portion (323c) through the second grounding member (422). For example, the resonance splitting phenomenon may mean a phenomenon in which the frequency of the first parasitic resonance formed by the first surface current (J1) formed on the surface of the second housing (320) is shifted to a specific frequency band under the influence of the second parasitic resonance (521) formed by the second surface current (J2) induced in the second support member (3231) and the grounded sixth side portion (323c).
[0199] A portion of the electronic device (300) where no surface current is displayed may be ground. For example, the ground may be ground included in a support member (e.g., a first support member (3131) or a second support member (3231), ground included in a printed circuit board (e.g., a first substrate assembly (361) or a second substrate assembly (362)), or ground included in a display (e.g., a first display (330) or a second display (400)). FIG. 20A is a conceptual diagram illustrating an upper surface of the electronic device (300) according to various embodiments.
[0200] Referring to FIG. 20A, the fourth side portion (323a) of the second housing (320) of the electronic device (300) can be grounded to the second support member (3231) via the first ground member (421). For example, the first ground member (421) can electrically connect the fourth side portion (323a) and the second support member (3231). For example, the first ground member (421) can electrically connect the fourth side portion (323a) and the second support member (3231) via a printed circuit board (e.g., the second board assembly (362)).
[0201] The electronic device (300) may include a wireless communication circuit (600). The fourth side portion (323a) may be electrically connected to the wireless communication circuit (600). In one embodiment, the fourth side portion (323a) may be electrically connected to the third corner portion (323d) via a first connection portion (821) including a first switch (821a) and a first conductive line (821b). One end of the first connection portion (821) may be electrically connected to the fourth side portion (323a). The other end of the first connection portion (821) may be electrically connected to the third corner portion (323d). For example, the first connection portion (821) may be a logical connection as a connection line for connecting the fourth side portion (323a) and the third corner portion (323d). For another example, the first switch (821a) and the first conductive line (821b) may be formed on a printed circuit board (e.g., the second board assembly (362)). For another example, the fourth side portion (323a) and the third corner portion (323d) may operate as a radiator (720). For another example, the fourth side portion (323a) may operate as a radiator (720) together with the third corner portion (323d) via the first switch (821a). For example, the fourth side portion (323a) may operate as a radiator solely via the first switch (821a).
[0202] In one embodiment, the sixth side portion (323c) may be electrically connected to the third corner portion (323d) via the second matching circuit portion (922). For example, the second matching circuit portion (922) may include a third switch (922a) and at least one second inductor (922b). The second matching circuit portion (922) may electrically connect the sixth side portion (323c) and the third corner portion (323d). In another example, the second matching circuit portion (922) may electrically connect the sixth side portion (323c) and the third corner portion (323d) via a printed circuit board (e.g., the second board assembly (362)). For example, one end of the second matching circuit portion (922) may be electrically connected to the sixth side portion (323c). The other end of the second matching circuit portion (922) may be electrically connected to the third corner portion (323d). A second parasitic resonance (522) may be formed from the first ground member (421) connected to the fourth side portion (323a) to the third corner portion (323d), the second matching circuit portion (922), and the sixth side portion (323c).
[0203] In one embodiment, the second matching circuit (922) may be a tunable matching circuit including a plurality of inductors having various inductance values. For example, the second inductors (922b) included in the second matching circuit (922) may be plural. For example, the plurality of second inductors (922b) may be connected in parallel with the third switch (922a). The third switch (922a) may be selectively connected to one of the plurality of second inductors (922a).
[0204] For example, the inductance value of the second matching circuit unit (922) can be determined based on the frequency of the transmission signal of the electronic device (300). For example, the inductance value of the second matching circuit unit (922) can have a sufficient size to operate close to open at the frequency of the transmission signal of the electronic device (300). For example, the inductance value of the second matching circuit unit (922) can be set to exceed a predetermined threshold value so that the sixth side portion (323c) is not electromagnetically coupled with the radiator (720). In other words, the electronic device (300) can control the second parasitic resonant frequency (521) while minimizing the influence on the radiator (720) through the second matching circuit unit (922). For example, the inductance value of the second matching circuit (922) may have various values such as about 39 nH, about 56 nH, or about 100 nH, but is not limited thereto.

For example, the current distribution formed on the surface of the second housing (320) in the electronic device (300) may be formed to face the grounding point of the fourth side portion (323a) from the hinge structure (340). As another example, the current distribution formed on the surface of the second housing (320) in the electronic device (300) may be formed to face the grounding point where the fourth side portion (323a) and the first grounding member (421) are connected from the hinge structure (340).

The second surface current (J2) induced on the at least one grounded conductive side surface may generate a second parasitic resonance.

[0277] The electronic device (3100) may be a foldable terminal having conductive sides or a metal frame (e.g., a first side (313a), a second side (313b), a third side (313c), a first edge (313d), a second edge (313e), a fourth side (323a), a fifth side (323b), a sixth side (323c), a third edge (323d), a fourth edge (323e)). For example, the first housing (1031), the second housing (1032), and the third housing (1033) may each include conductive sides. At least one of the conductive sides may be grounded to a support member of at least one of the first housing (1031), the second housing (1032), or the third housing (1033). At least one of the conductive sides may be a part of the first housing (1031), the second housing (1032), or the third housing (1033) through which a surface current may be induced. The direction of the surface current induced in at least one of the conductive sides may be the same as the direction of the surface current induced in the first housing (1031) or the direction of the surface current induced in at least one of the second housing (1032) or the third housing (1033). The surface current induced in the surface of the electronic device (3100) in the folded state may generate a first parasitic resonance. The first parasitic resonance may be referred to as a PPW resonance.
[0278] In the folded electronic device (3100), when at least one of the conductive sides is grounded to a support member of at least one of the first housing (1031), the second housing (1032), or the third housing (1033), the direction of a surface current (e.g., the first surface current (J1)) induced on the surface of the electronic device (1) and the direction of a surface current (e.g., the second surface current (J2)) induced on the at least one grounded conductive side may be opposite to each other. The surface current (e.g., the second surface current (J2)) induced on the at least one grounded conductive side may generate a second parasitic resonance. The second parasitic resonance may shift the frequency band of the first parasitic resonance. For example, the second parasitic resonance may generate a resonance splitting phenomenon with respect to the first parasitic resonance.
[0279] FIG. 31d is a graph (1220) illustrating the frequency of a first parasitic resonance formed by a surface current of an electronic device (3100) in a folded state according to various embodiments.
[0280] Referring to FIG. 31D, the X-axis may represent a frequency band (frequency band / MHz), and the Y-axis may represent a reflection coefficient (dB) of an electric field mode of an electronic device (3100) in a folded state. The first graph (1221) represents a frequency of a first parasitic resonance formed by a surface current induced on the surface of a Z-type foldable terminal (3100) in a folded state. In the electronic device (3100) in a folded state according to the present disclosure, when at least one of the conductive side surfaces is grounded to a support member of at least one of the first housing (1031), the second housing (1032), or the third housing (1033), the frequency band of the first parasitic resonance may shift according to a resonance splitting phenomenon. For example, the first graph (1211) may shift to a frequency band that does not overlap with the frequency band of a transmission signal of a radiator of the electronic device (3100). Accordingly, the communication performance and efficiency of the electronic device (3100) can be improved.
[0281] FIG. 32A is a conceptual diagram illustrating an electronic device (3200) according to various embodiments.
[0282] FIG. 32b is a conceptual diagram illustrating one side of an electronic device (3200) according to various embodiments.
[0283] Referring to FIGS. 32A and 32B , an electronic device (3200) may include the electronic device (101) of FIG. 1 and the electronic device (300) of FIGS. 2A to 29B , or may be identical and / or similar thereto in various aspects, and may include additional features not described above. For example, the electronic device (3200) may be a wide foldable terminal. The electronic device (3200) may include a first housing (1051), a hinge structure (1061) coupled with one side of the first housing (1051), and a second housing (1052) coupled with one side of the hinge structure (1061). In the electronic device (3200), the hinge structure (1061) may be aligned in the X-axis direction with respect to the XY plane. Accordingly, the first housing (1051) or the second housing (1052) can be folded in the Y-axis direction with the hinge structure (1061) aligned in the X-axis direction as the central axis. For example, the electronic device (3200) can be folded with the hinge structure (1061) as the central axis so that the first surface of the first housing (1051) and the first surface of the second housing (1052) face each other.
[0284] FIG. 32c is a conceptual diagram illustrating the distribution of surface current induced on the surface of an electronic device (3200) in a folded state according to various embodiments.
[0285] Referring to FIG. 32c, when the first surface of the first housing (1051) and the first surface of the second housing (1052) are folded to face each other with the hinge structure (1061) as the central axis in the electronic device (3200), the first housing (1051), the hinge structure (1061), and the second housing (1051) can be electrically coupled.
[0286] For example, the first housing (1051), the hinge structure (1061), and the second housing (1052) of the electronic device (3200) in the folded state can be equivalentized in the form of shielded parallel plates. Since the electric field (E-Field) of the electronic device (3200) in the folded state is proportional to the electric potential, the potential is zero (0) at the hinge structure (1061) where the first housing (1051) and the second housing (1052) are grounded, and thus the magnitude of the electric field can be zero (0). On the other hand, since the electric potential increases as one moves away from the hinge structure (1061) in the electronic device (3200) in the folded state, the magnitude of the electric field can also increase.
[0287] The surface current induced on the surface of the electronic device (3200) in the folded state can flow circulatingly from the hinge structure (1061) to one side of the first housing (1051), from one side of the first housing (1051) to the other side of the first housing (1051), from the other side of the first housing (1051) to the other side of the second housing (1051), from the other side of the second housing (1052) to one side of the second housing (1052), and from one side of the second housing (1052) back to the hinge structure (1061).
[0288] In one embodiment, the electronic device (3200) may be a foldable terminal having or including conductive sides or a metal frame (e.g., a first side (313a), a second side (313b), a third side (313c), a first edge (313d), a second edge (313e), a fourth side (323a), a fifth side (323b), a sixth side (323c), a third edge (323d), a fourth edge (323e)). For example, the first housing (1051) and the second housing (1052) may each include conductive sides. At least one of the conductive sides may be a part of at least one of the first housing (1051) or the second housing (1052) such that a surface current may be induced. The direction of the surface current induced in at least one of the conductive sides may be the same as the direction of the surface current induced in the first housing (1051) or the direction of the surface current induced in the second housing (1052). The surface current induced in the first housing (1051) or the second housing (1052) may generate a first parasitic resonance. At least one of the conductive sides may be grounded to a support member of at least one of the first housing (1051) or the second housing (1052). When at least one of the conductive sides is grounded to the support member of at least one of the first housing (1051) or the second housing (1052), a surface current (e.g., a second surface current (J2)) may be induced on the surface of the grounded conductive side, the surface current flowing in the opposite direction to the surface current (e.g., the first surface current (J1)) induced in the first housing (1051) or the second housing (1052). Surface currents induced on the surface of the grounded conductive side can generate a second parasitic resonance. The second parasitic resonance can change the frequency band of the first parasitic resonance. For example, a resonance splitting phenomenon can occur between the frequency of the second parasitic resonance and the frequency of the first parasitic resonance.
[0289] FIG. 32d is a graph (1230) illustrating the frequency (1231) of a first parasitic resonance formed by a surface current induced on the surface of an electronic device (3200) in a folded state according to various embodiments.
[0290] Referring to FIG. 32d, the X-axis may represent a frequency band (frequency band / MHz), and the Y-axis may represent a reflection coefficient (dB) of a mode of an electric field formed in an electronic device (3200) in a folded state. The first graph (1231) represents a frequency of a first parasitic resonance formed by a surface current induced on the surface of a wide foldable terminal (3200) in a folded state. When at least one of the conductive side surfaces in the electronic device (3200) in a folded state according to the present disclosure is grounded to a support member of at least one of the first housing (1051) and the second housing (1052), the frequency band of the second parasitic resonance may shift according to the resonance splitting phenomenon. For example, the first graph (1231) may shift to a frequency band that does not overlap with the frequency band of a transmission signal of a radiator of the wide foldable terminal (3200). Therefore, the communication performance and efficiency of the wide foldable terminal (3200) may be improved.
