Description
BACKGROUND
1. Field

The present disclosure relates to an electronic device comprising an antenna.


2. Description of Related Art

A foldable electronic device may include a first housing and a second housing configured to be rotatably connected to the first housing through a hinge device. In such a foldable electronic device, at least a portion of a metal frame (e.g., a metal bezel) provided on the side surface of the first housing and/or the second housing may be used as an antenna. The antenna may be designed so that radiation performance may not be degraded according to a folding or unfolding operation of the electronic device.


SUMMARY

An electronic device may include a foldable electronic device including a first housing and a second housing foldably connected to the first housing through a hinge device. The electronic device may include a flexible display used in an unfolding state and provided to receive support of at least a portion of the second housing from the first housing through the hinge device. The foldable electronic device may include at least one antenna (e.g., a metal frame antenna) provided in an interior space of at least one housing or using at least a portion of a conductive side surface. The volume and number of such antennas may be determined based on a frequency, a bandwidth, and/or a type for each service provided by the electronic device.


The foldable electronic device may use a metal frame to reinforce its rigidity and, in a folded state, a metal frame of the first housing and a metal frame of the second housing may form a flattened “U” shape. However, planar parasitic resonance may occur through a conductive sheet (e.g., a copper (Cu) sheet) of the flexible display provided therein. Such a parasitic resonance may degrade radiation performance of the foldable electronic device.


The first housing and conductive portions included in the first housing, such as a conductive support member provided to the first housing and in which parasitic resonance may occur according to radiation current, the ground of the flexible display, the conductive side surface, and/or the metal frame, may be collectively referred to as the first housing. Similarly, the second housing and conductive portions included in the second housing, such as a conductive support member provided to the second housing and in which parasitic resonance may occur according to radiation current, the ground of the flexible display, the conductive side surface, and/or the metal frame, may be collectively referred to as the second housing.


Various embodiments of the present disclosure may provide an electronic device including an antenna that may help improve radiation performance by guiding a parasitic resonance frequency generated in a folded state to a band other than an operating frequency band (e.g., an out band) of the antenna.


According to an aspect of the disclosure, an electronic device includes: a first housing; a second housing including a second support member; a hinge structure coupled with the first housing and the second housing so that the first housing and the second housing are foldable relative to each other using the hinge structure as a central axis; and a wireless communication circuit provided on the second support member of the second housing, wherein the second housing further includes: a sixth side portion including a first conductive portion; a fifth side portion facing the sixth side portion and including a second conductive portion; a fourth side portion facing the hinge structure and including a third conductive portion; a third corner portion between the sixth side portion and the fourth side portion and including a fourth conductive portion; a fourth corner portion between the fifth side portion and the fourth side portion and including a fifth conductive portion; and a first matching circuit provided on the second support member, electrically coupled with the sixth side portion, and configured to induce a second surface current having a second phase opposite to a first phase of a first surface current induced on the first housing, the second housing, and the hinge structure based on the electronic device being in a folded state in which the first housing and the second housing are folded with respect to each other.


According to an aspect of the disclosure, an electronic device includes: a first housing; a second housing including a second support member; a hinge structure coupled with the first housing and the second housing so that the first housing and the second housing are foldable relative to each other using the hinge structure as a central axis; and a wireless communication circuit provided on the second support member of the second housing, wherein the second housing further includes: a sixth side portion including a first conductive portion; a fifth side portion facing the sixth side portion and including a second conductive portion; a fourth side portion facing the hinge structure and including a third conductive portion; a third corner between the sixth side portion and the fourth side portion and including a fourth conductive portion; a fourth corner portion between the fifth side portion and the fourth side portion and including a fifth conductive portion; and a first matching circuit on the second support member, electrically coupled with the sixth side portion and the fourth corner portion, and configured to induce a second surface current having a second phase opposite to a first phase of a first surface current induced to the first housing, the second housing, and the hinge structure based on the electronic device being in a folded state in which the first housing and the second housing are folded with respect to each other using the hinge structure as the central axis.


In addition, various effects directly or indirectly identified herein may be provided.


The effects that may be obtained from the present disclosure are not limited to the effects mentioned above and still other effects not mentioned may be clearly understood by one of ordinary skill in the art to which the present disclosure pertains from the following description.

According to an embodiment, the electronic device 101 may communicate with the electronic device 104 via the server 108. According to an embodiment, the electronic device 101 may include a processor 120, memory 130, an input module 150, a sound output module 155, a display module 160, an audio module 170, a sensor module 176, an interface 177, a connecting terminal 178, a haptic module 179, a camera module 180, a power management module 188, a battery 189, a communication module 190, a subscriber identification module (SIM) 196, or an antenna module 197.

With reference to FIGS. 5A to 8B, the electronic device 300 may include and/or may be similar in many respects to the electronic device 300 described above with reference to FIGS. 2A to 4, and may include additional features not mentioned above. Consequently, repeated descriptions of the electronic device 300 described above with reference to FIGS. 2A to 4 may be omitted for the sake of brevity.


With reference to FIG. 5A, the electronic device 300 may be folded so that one surface of the first housing 310 (e.g., first surface 311 of FIG. 2A) and one surface of the second housing 320 (e.g., second surface 312 of FIG. 2A) face each other using the hinge structure 340 as the central axis. In the electronic device 300, when the one surface of the first housing 310 (e.g., first surface 311) and one surface of the second housing 320 (e.g., second surface 312) are folded to face each other using the hinge structure 340 as the central axis, the first housing 310, the hinge structure 340, and the second housing 320 may be electrically connected and, as the first housing 310 and the second housing 320 are adjacent, electromagnetic coupling may occur between the first housing 310 and the second housing 320.


With reference to FIGS. 5B and 7A, the first housing 310, the hinge structure 340, and the second housing 320 of the electronic device 300 in the folded state may become equivalent to the form of a shielded parallel plate. For example, the electronic device 300 equivalent to the form of the shielded parallel plate may also be referred to as a shielded parallel plate model 300. Hereinafter, the first housing 310 may also be referred to as a first plate 310, and the second housing 320 may be referred to as a second plate 320.


With reference to FIGS. 6A, 6B, and 7B, since the electric field (E-Field) of the electronic device 300 in the folded state may be proportional to potential, the potential may be zero (0) in the hinge 340 to which the first plate 310 and the second plate 320 are grounded and magnitude of the electric field may be zero (0), accordingly. Alternatively, in the electronic device 300 in the folded state, since the potential may increase as a distance from the hinge 340 increases, the magnitude of the electric field may also increase.


With reference to FIGS. 8A and 8B, in the shielded parallel plate model 300, a first surface current J1 may be formed on the surface of the first plate 310, the hinge 340, and the second plate 320. The first surface current J1 may be formed in the form of a current circulating the first plate 310, the hinge 340, and the second plate 320. For example, the first surface current J1 may circulate from one side surface of the second plate 320 (e.g., the fourth side surface 323a of second housing 320) to the hinge 340, from the hinge 340 to one side surface of the first plate 310 (e.g., the first side surface 313a of first housing 310), and back to one side surface of the second plate 320 (e.g., the fourth side surface 323a of second housing 320). As another example, a direction of the surface current induced in the first plate 310 may be opposite to a direction of the surface current induced in the second plate 320.

FIG. 9B is a graph 1110 showing a reflection coefficient (S1, 1) 1111 of resonance frequency formed in the electronic device 300 in the folded state that does not include a conductive portion on the side surface, according to various embodiments. FIG. 9C is a conceptual diagram illustrating, in the shielded parallel plate model, an electric field mode of the second housing 320 of the electronic device 300 in the folded state that does not include a conductive portion on the side surface, according to various embodiments.


With reference to FIG. 9A, the shielded parallel plate model corresponding to the electronic device 300 in the folded state that does not include a conductive portion on the side surface may be the same as or similar to the shielded parallel plate model 300 of FIG. 5B or the shielded parallel plate model 300 of FIG. 8A.


With reference to FIG. 9B, a first parasitic resonance frequency 1 formed in the electronic device 300 in the folded state that does not include a conductive portion on the side surface may operate at about 888.1253 MHz (e.g., 1111 graph).


With reference to FIG. 9C, since a mode of the electric field illustrated in the shielded parallel plate model corresponding to the electronic device 300 in the folded state that does not include a conductive portion on the side surface is proportional to the potential as shown in FIGS. 6A and 6B, the potential may be zero (0) in the hinge 340 to which the first plate 310 and the second plate 320 are grounded and the magnitude of the electric field may be zero (0), accordingly. Alternatively, in the electronic device 300 in the folded state, since the potential may increase as a distance away from the hinge 340 increase, the magnitude of the electric field may also increase. Due to the first surface current J1 formed on the surface of the electronic device 300 in the folded state, an electric field (e.g., a first parasitic resonance) may occur. The mode of the electric field of the electronic device 300 by the first parasitic resonance may be referred to as a first mode.

The second plate 320 may physically couple with a third corner portion 323d provided between the fourth side portion 323a and the sixth side portion 323c and a fourth corner portion 323e provided between the fourth side portion 323a and the fifth side portion 323b. At least one of 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 may be formed of a conductive material. The fourth side portion 323a may include a first fragmentation portion 3261 and a second fragmentation portion 3262 formed of nonconductive material. The fifth side portion 323b may include a third fragmentation portion 3263 and a fourth fragmentation portion 3264. The sixth side portion 323c may include a fifth fragmentation portion 3265 and a sixth fragmentation portion 3266.


With reference to FIG. 10B, a resonance frequency 1 formed in the electronic device 300 in the folded state that includes the plurality of side portions (e.g., the first side portion 313a, the second side portion 313b, the third side portion 313c, the fourth side portion 323a, the fifth side portion 323b, and the sixth side portion 323c) is about 872 MHz and it can be seen to be low shifted when compared to the resonance frequency described with reference to FIG. 9B (e.g., 1121 graph).


With reference to FIG. 10C, 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 may not be grounded to the ground of the second plate 320.

FIG. 11A is a conceptual diagram illustrating the shielded parallel plate model corresponding to the electronic device 300 in the folded state in which the plurality of side portions 313a to 323c formed of conductive material are grounded, according to various embodiments. FIG. 11B is a graph 1130 showing a reflection coefficient (S1,1) 1131 of resonance frequency formed in the electronic device 300 in the folded state in which the plurality of side portions 313a to 323c formed of conductive material are grounded, according to various embodiments.

With reference to FIG. 11B, when the plurality of side portions 313a to 323c are grounded, a resonance frequency 1 formed in the electronic device 300 in the folded state may operate at a lower frequency of about 840 MHz that may be lower than the resonance frequencies described with reference to FIGS. 9B and 10B. For example, a position of the resonance frequency 1 of FIG. 11C on the graph 1130 may be low shifted compared to the position of the resonance frequency 1 of FIG. 9B and the position of the resonance frequency 1 of FIG. 10B. This may represent that, when the foldable electronic device 300 is in the folded state, grounding of the plurality of side portions 313a to 323c may affect the operating frequency band.


With reference 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 may be electrically connected to the ground of the second plate 320.

The third corner portion 323d may be electrically connected to the ground 423 of the second plate 320. For example, the overall electric field mode of the second plate 320 that includes 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 may be substantially similar and/or the same as the first mode that is the electric mode of the second plate 300 as described with reference to FIG. 9C.



FIG. 12A is a conceptual diagram illustrating, in the shielded parallel plate model, the current distribution of the electronic device 300 in the folded state in which the plurality of side portions 313a to 323c formed of conductive material are grounded, according to various embodiments.

With reference to FIG. 12A, the surface current formed on the surface of the second plate 320 based on the X-Y plane may be formed to flow from the hinge 340 into one side surface of the second plate 320 (e.g., fourth side portion 323a of second housing 320). In each of 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, a direction of the surface current induced on the surface at a cavity parasitic resonance frequency may be substantially similar and/or the same as a direction of the surface current formed on the surface of the second plate 320.


With reference to FIG. 12B, a 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 similar and/or the same as a direction of the first surface current J1 formed on the surface of the second plate 320.



FIG. 13A is a conceptual diagram illustrating an electric field mode of the second housing 320 and the sixth side portion 323c of the electronic device 300 in the shielded parallel plate model, according to various embodiments. FIG. 13B is a conceptual diagram illustrating the surface current of the second housing 320 and the surface current of the sixth side surface 323c of the electronic device 300 in the shielded parallel plate model, according to various embodiments.


With reference to FIG. 13A, in the shielded parallel plate model, the sixth side portion 323c may be grounded to the second plate 320 through a ground member 420. A second parasitic resonance having a frequency with a wavelength of about λ/4 may occur in the sixth side surface 323c grounded to the second plate 320 through the ground member 420. A mode of electric field by the second parasitic resonance formed in the grounded sixth side portion 323c may be referred to as a second mode.


With reference to FIG. 13B, in the shielded parallel plate model, a direction of the second surface current J2 induced on the surface at the frequency of the second parasitic resonance having the frequency with the wavelength of about λ/4, occurring in the sixth side portion 323c grounded to the second plate 320 through the ground member 420, may be opposite to a direction of the first surface current J1 induced on the surface of the second plate 320. In the electronic device 300 in the folded state, when the sixth side portion 323c is electrically connected to the ground of the second plate 320, the electric field corresponding to the first mode by the first surface current J1 induced on the surface of the second plate 320 and the electric field corresponding to the second mode by the second parasitic resonance formed by the second surface current J2 induced to the sixth side portion 323c electrically connected to the ground of the second plate 320 may be formed in the electronic device 300. That is, the electric field of the first mode and the electric field of the second mode that differ from each other may be formed 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 parallel plate waveguide (PPW) resonance frequency. The frequency of the second parasitic resonance may be referred to as a line resonance frequency.


A phenomenon that the direction of the second surface current J2 induced on the surface of the sixth side surface 323c due to the parasitic resonance frequency with the wavelength of λ/4 and the direction of the first surface current J1 induced on the surface of the second plate 320 may be referred to as a reverse current effect. The present disclosure provides a structure capable of controlling the first parasitic resonance formed in the electronic device 300 in the folded state using the second parasitic resonance, according to the reverse current effect. That is, the present disclosure provides the electronic device 300 to improve antenna performance in a target band by shifting the frequency band of the first parasitic resonance using the second parasitic resonance.

FIG. 14B is a perspective view of the shielded parallel plate model corresponding to the electronic device 300 in which the PPW resonance is formed, according to various embodiments.

FIG. 14D is a conceptual diagram illustrating, in the shielded parallel plate model, an electric field mode of the electronic device 300 in which the PPW resonance is formed, according to various embodiments.


With reference to FIGS. 14A and 14B, the shielded parallel plate model corresponding to the electronic device 300 in the folded state that does not include side portions or in which the side portions are not formed of conductive material may be the same as or similar to the shielded parallel plate model 300 of FIG. 5B, the shielded parallel plate model 300 of FIG. 8A, or the shielded parallel plate model 300 of FIG. 9A. According to various embodiments, a horizontal length of each of the first plate 310 and the second plate 320 may be about 72 millimeters (mm) based on the X-Y plane, for example. According to various embodiments, a vertical length of each of the first plate 310 and the second plate 320 may be about 82 mm based on the X-Y plane, for example.


With reference to FIG. 14C, a resonance frequency 1141 (1) formed in the electronic device 300 in the folded state that does not include side portions or in which the side portions are not formed of conductive material may be positioned at about −8.89351 dB at the frequency of about 888 MHz, for example.


With reference to FIG. 14D, in the case of an electric field mode illustrated in the shielded parallel plate model corresponding to the electronic device 300 in the folded state that does not include side portions or in which the side portions are not formed of conductive material, as shown in FIGS. 6A, 6B, and 9C, the electric field (E-Field) of the electronic device 300 in the folded state is proportional to potential and the potential is zero (0) at the hinge 340 to which the first plate 310 and the second plate 320 are grounded and magnitude of the electric field may be zero (0), accordingly. Alternatively, in the electronic device 300 in the folded state, since the potential increases as a distance away from the hinge 340 increases, the magnitude of the electric field may also increase. The first parasitic resonance may occur due to the first surface current J1 formed on the surface of the electronic device 300 in the folded state. The mode of the electric field of the electronic device 300 by the first parasitic resonance may be referred to as the first mode.

FIG. 15E is a conceptual diagram illustrating, in the shielded parallel plate model, the first mode corresponding to electric field formed according to the first parasitic resonance in the electronic device 300, according to various embodiments.


With reference to FIG. 15A, in the shielded parallel plate model corresponding to the electronic device 300, according to an embodiment, the third side surface 313c may be grounded to the ground of the first plate 310 through a ground member 420.


With reference to FIG. 15B, based on the X-Y plane, according to various embodiments, a horizontal length of each of the first plate 310 and the second plate 320 may be about 72 mm, for example. Based on the X-Y plane, according to various embodiments, a vertical length of each of the first plate 310 and the second plate 320 may be about 82 mm, for example. Based on the X-Y plane, according to various embodiments, a horizontal length of the sixth side surface 323c may be about 67 mm, as an example. For example, the ground member 420 may be and/or may include an inductor having an inductance value of about 2.7 nanoHenry (nH).


With reference to FIG. 15C, the first parasitic resonance 1152 (existing PPW resonance (2)) formed by the first surface current J1 of the second housing 320 may be formed in the electronic device 300 in the folded state. The first parasitic resonance 1152 (existing PPW resonance (2)) and the second parasitic resonance 1151 (line resonance 1) by the second surface current J2 induced on the sixth side surface 323c grounded to the second plate 320 may be formed in the electronic device 300 in the folded state through the ground member 420. A frequency band of the frequency of the first parasitic resonance 1152 (existing PPW resonance (2)) may be shifted by the second parasitic resonance 1151 (line resonance (1)). For example, the frequency band of the first parasitic resonance 1153 (shifted PPW resonance (3)) may be about −9.1914061 dB at about 940 MHz. The shape in which the frequency band shifts may be referred to as a resonance-splitting phenomenon.


With reference to FIG. 15D, the second parasitic resonance may occur in the electronic device 300 in the folded state due to the second surface current J2 induced on the sixth side surface 323c grounded to the second plate 320 through the ground member 420. The mode of the electric field of the electronic device 300 by the second parasitic resonance may be referred to as the second mode.


With reference to FIG. 15E, the first parasitic resonance may occur due to the first surface current J1 formed on the surface of the electronic device 300 in the folded state. The mode of the electric field of the electronic device 300 by the first parasitic resonance may also be referred to as the first mode.


That is, the electric field of the first mode and the electric field of the second mode that differ from each other may be formed in the electronic device 300.



FIG. 16A is a conceptual diagram illustrating, in the shielded parallel plate model, the current distribution of the electronic device 300 in which the first parasitic resonance and the second parasitic resonance are formed, according to various embodiments. FIG. 16B is a conceptual diagram illustrating, in the shielded parallel plate model, the current distribution of the electronic device 300 in which the first parasitic resonance and the second parasitic resonance are formed, according to various embodiments.


With reference to FIGS. 16A and 16B, a direction of the second surface current J2 induced to the sixth side portion 323c that is grounded to the ground of the second plate 320 through the ground member 420 may be formed in a direction opposite to a direction of the second surface current J2 induced on the surface of the second plate 320 due to the grounding. For example, in the shielded parallel plate model corresponding to the electronic device 300, the first surface current J1 formed on the surface of the second plate 320 may be formed in the −Y-axis direction based on the X-Y plane. In the shielded parallel plate model, the second surface current J2 induced on the sixth side surface 323c grounded to the second plate 320 through the ground member 420 in the second plate 320 may be formed in the +Y-axis direction that is opposite to the direction of the first surface current J1.


In the shielded parallel plate model, since the second surface current J2 induced to the sixth side portion 323c grounded to the ground of the second plate 320 through the ground member 420 is formed in the direction opposite to the direction of the first surface current J1 induced on the surface of the second plate 320, a resonance-splitting phenomenon may occur between the frequency of the first parasitic resonance by the first surface current J1 formed on the surface of the second plate 320 and the frequency of the second parasitic resonance by the second surface current J2 induced to the sixth side portion 323c grounded to the ground of the second plate 320 through the ground member 420 in the shielded parallel plate model. For example, the resonance-splitting phenomenon may represent that, as shown in FIG. 15C, the frequency of the first parasitic resonance formed by the first surface current J1 formed on the surface of the second plate 320 shifts to a specific frequency band without maintaining the existing frequency band due to the effect of the second parasitic resonance formed by the second surface current J2 induced to the sixth side portion 323c grounded to the second plate 320.

FIG. 17B is a conceptual diagram illustrating, in the shielded parallel plate model, the current distribution of the electronic device 300 in which the first parasitic resonance is formed, according to various embodiments.


With reference to FIGS. 17A and 17B, the direction of the second surface current J2 induced to the sixth side portion 323c not grounded to the ground of the second plate 320 may be formed in the same direction as the direction of the second surface current J2 induced on the surface of the second plate 320, which may be different from the direction of the second surface current J2 induced to the sixth side portion 323c grounded to the ground of the second plate 320 through the ground member 420 as shown in FIGS. 16A and 16B. For example, when the sixth side portion 323c is not grounded to the ground of the second plate 320, the resonance-splitting phenomenon may not occur.



FIG. 18 is a top view illustrating the electronic device 300, according to various embodiments.


With reference to FIG. 18, the second housing 320 of the electronic device 300 may include the second support member 3231, the plurality of side portions 323a to 323c formed of conductive material, and the plurality of corner portions 323d and 323e. For example, the fourth side portion 323a may be provided in the −Y-axis direction of the second housing 320 based on the X-Y plane. For example, the fourth side portion 323a may be provided to face the hinge structure 340 based on the X-axis in the second housing 320. For example, the fourth side portion 323a may include the first fragmentation portion 3261 and the second fragmentation portion 3262 formed of nonconductive material.


The fifth side portion 323b may be provided in the −X-axis direction of the second housing 320 based on the X-Y plane. The fifth side portion 323b may include the third fragmentation portion 3263 and the fourth fragmentation portion 3264 formed of nonconductive material. For example, the fifth side portion 323b may be electrically separated from the hinge structure 340 through the third fragmentation portion 3263.


The sixth side portion 323c may be provided in the +X-axis direction of the second housing 320, based on the X-Y plane. For example, the sixth side portion 323c may be provided to be symmetrical to the fifth side portion 323b based on the Y-axis in the second housing 320.

FIG. 19A is a conceptual diagram illustrating the top surface of the electronic device 300 in a wireless communication system, according to various embodiments.


With reference to FIG. 19A, in an embodiment, in the second housing 320 of the electronic device 300, the fourth side surface 323a may be grounded to the second support member 3231 through a first ground member 421. For example, the first ground member 421 may electrically connect the fourth side surface 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 through a PCB (e.g., second plate assembly 362).


The electronic device 300 may include the wireless communication module 192. The fourth side portion 323a may be electrically connected to the wireless communication module 192. In an embodiment, the fourth side portion 323a may be electrically connected to the third corner portion 323d through a first connecting portion 821 that includes a first switch 821a and a first conductive line 821b. One end of the first connecting portion 821 may be electrically connected to the fourth side portion 323a. The other end of the first connecting portion 821 may be electrically connected to the third corner portion 323d. For example, the first connecting 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 in a PCB (e.g., second plate assembly 362). For example, the fourth side portion 323a and the third corner portion 323d may operate as a radiator 720. As another example, the fourth side portion 323a may operate as the radiator 720 along with the third corner portion 323d through the first switch 821a. As yet another example, the fourth side portion 323a may operate alone as the radiator 720 through the first switch 821a.


According to an embodiment, the sixth side portion 323c may be grounded to the second support member 3231 through a first matching circuit unit 921. For example, the first matching circuit unit 921 may include a second switch 921a and at least one first inductor 921b. As another example, the first matching circuit unit 921 may electrically connect the sixth side portion 323c and the second support member 3231. As yet another example, the first matching circuit unit 921 may electrically connect the sixth side portion 323c and the second support member 3231 through the PCB (e.g., second plate assembly 362). For example, one end of the first matching circuit unit 921 may be electrically connected to the sixth side portion 323c. The other end of the second ground member 422 may be electrically connected to the second support member 3231. Second parasitic resonance 521 may be formed in the first matching circuit unit 921 and the sixth side portion 323c.


In an embodiment, the first matching circuit unit 921 may be a tunable matching circuit unit that includes a plurality of inductors having various inductance values. For example, the number of first inductors 921b included in the first matching circuit unit 921 may be plural (e.g., a positive integer greater than one (1)). For example, the plurality of first inductors 921b may be connected in parallel to a second switch 921a. The second switch 921a may be selectively connected to one inductor among the plurality of first inductors 921b. For example, an inductance value of the first matching circuit unit 921 may be determined based on a frequency of a transmission signal of the electronic device 300. As another example, the inductance value of the first matching circuit unit 921 may 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 first matching circuit unit 921 may be set to exceed a predetermined threshold so that the sixth side portion 323c does not electromagnetically couple with the radiator 720. That is, the electronic device 300 may control the second parasitic resonance frequency 521 while minimizing the effect on the radiator 720 through the first matching circuit unit 921. For example, the inductance value of the first matching circuit unit 921 may have various values, such as, but not limited to, about 39nH, about 56nH, or about 100nH.



FIG. 19B is a conceptual diagram illustrating the distribution of the surface current of the electronic device 300 in a wireless communication system, according to various embodiments.


With reference to FIG. 19B, in the electronic device 300 in the folded state, the current distribution formed on the surface of the second housing 320 may be formed from the hinge structure 340 toward the fourth side portion 323a. For example, in the electronic device 300, the current distribution formed on the surface of the second housing 320 may be formed from the hinge structure 340 toward a ground point of the fourth side portion 323a electrically connected to the second support member 3231. For example, in the electronic device 300, the current distribution formed on the surface of the second housing 320 may be formed from the hinge structure 340 toward the ground point at which the fourth side portion 323a and the first ground member 421 are connected.


In the electronic device 300, 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 may be the same and/or may be similar in many respects to the electric field distribution described with reference to FIGS. 19C and 19D.



FIG. 19C is a conceptual diagram illustrating distribution of the surface current of one surface of the electronic device 300, according to various embodiments.



FIG. 19D is a conceptual diagram illustrating distribution of the surface current of one surface of the electronic device 300, according to various embodiments.


With reference to FIGS. 19C and 19D, a direction of the second surface current J2 induced to the sixth side portion 323c that is grounded to the second support member 3231 through the first matching circuit unit 921 may be formed in a direction opposite to a direction of the second surface current J2 induced on the surface (e.g., second rear cover 324) of the second housing 320 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 X-Y plane. In the second housing 320 of the electronic device 300, the second surface current J2 induced to the sixth side portion 323c grounded to the second support member 3231 through the first matching circuit unit 921 may be formed in the +Y-axis direction that is opposite to the direction of the first surface current J1.


In the electronic device 300, since the second surface current J2 induced to the sixth side portion 323c grounded to the second support member 3231 through the first matching circuit unit 921 is formed in the direction opposite to the direction of the first surface current J1 induced on the surface of the second housing 320, a resonance-splitting phenomenon may occur between the frequency of the first parasitic resonance by the first surface current J1 formed on the surface of the second plate 320 in the electronic device 300 and the frequency of the second parasitic resonance 521 by the second surface current J2 induced to the sixth side portion 323c grounded to the second support member 3231 of the second plate 320 through the second ground member 422. For example, the resonance-splitting phenomenon may represent that the frequency of the first parasitic resonance formed by the first surface current J1 formed on the surface of the second housing 320 shifts to a specific frequency band due to the effect of the second parasitic resonance 521 formed by the second surface current J2 induced to the sixth side portion 323c grounded to the second support member 3231.


In the electronic device 300, a portion in which the surface current is not displayed may be the ground.

One end of the first connecting portion 821 may be electrically connected to the fourth side portion 323a. The other end of the first connecting portion 821 may be electrically connected to the third corner portion 323d. For example, the first connecting portion 821 may be a logical connection as a connection line for connecting the fourth side portion 323a and the third corner portion 323d. As another example, the first switch 821a and the first conductive line 821b may be formed in the PCB (e.g., second plate assembly 362).

The second matching circuit unit 922 may electrically connect the sixth side portion 323c and the third corner portion 323d. For example, the second matching circuit unit 922 may electrically connect the sixth side portion 323c and the third corner portion 323d through the PCB (e.g., second plate assembly 362). As another example, one end of the second matching circuit unit 922 may be electrically connected to the sixth side portion 323c. The other end of the second matching circuit unit 922 may be electrically connected to the third corner portion 323d. The 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 unit 922, and the sixth side portion 323c.


In an embodiment, the second matching circuit unit 922 may be a tunable matching circuit unit that includes a plurality of inductors having various inductance values. For example, the number of second inductors 922b included in the second matching circuit unit 922 may be plural. For example, the plurality of second inductors 922b may be connected in parallel to the third switch 922a. The third switch 922a may be selectively connected to one inductor among the plurality of second inductors 922b.


For example, an inductance value of the second matching circuit unit 922 may be determined based on a frequency of a transmission signal of the electronic device 300. For example, the inductance value of the second matching circuit unit 922 may have a size sufficient to operate close to open at the frequency of the transmission signal of the electronic device 300.

For example, in the electronic device 3000 in the folded state, the surface current may flow from one side surface of the third housing 1013 into the second hinge structure 1022, from the second hinge structure 1022 into the one side surface of the second housing 1012, from one side surface of the second housing 1012 into the first hinge structure 1021, and from the first hinge structure 1021 into one side surface of the first housing 1011.


The electronic device 3000 may be and/or may include a foldable terminal having conductive side surfaces or metal frames (e.g., first side surface 313a, second side surface 313b, third side surface 313c, first corner 313d, second corner 313e, fourth side surface 323a, fifth side surface 323b, sixth side surface 323c, third corner 323d, and fourth corner 323e). For example, each of the first housing 1011, the second housing 1012, and the third housing 1013 may include conductive side surfaces. At least one of the conductive side surfaces may be grounded to at least one support member of the first housing 1011, the second housing 1012, or the third housing 1013.

In the electronic device 3000 in the folded state, when at least one of the conductive side surfaces is grounded to at least one support member of the first housing 1011, the second housing 1012, or the third housing 1013, the direction of the surface current (e.g., first surface current J1) induced on the surface of the electronic device 3000 and the direction of the surface current (e.g., second surface current J2) induced on the grounded at least one conductive side surface may be opposite to each other. The second surface current J2 induced on the grounded at least one conductive side surface may cause the second parasitic resonance. The second parasitic resonance may shift the frequency band of the first parasitic resonance. For example, the second parasitic resonance may cause the resonance-splitting phenomenon with respect to the first parasitic resonance.

For example, the first graph 1211 may shift to a frequency band that does not overlap a frequency band of a transmission signal from a radiator of the electronic device 3000. Therefore, communication performance and efficiency of the electronic device 3000 may be improved.

The surface current (e.g., first surface current J1) induced on the surface of the electronic device 3100 in the folded state may flow from one side surface of the third housing 1033 into the second hinge structure 1042, from the second hinge structure 1042 into one side surface of the second housing 1032, from one side surface of the second housing 1032 into the first hinge structure 1041, and from the first hinge structure 1041 into one side surface of the first housing 1031.


The electronic device 3100 may be a foldable terminal having conductive side surfaces or metal frames (e.g., first side surface 313a, second side surface 313b, third side surface 313c, first corner 313d, second corner 313e, fourth side surface 323a, fifth side surface 323b, sixth side surface 323c, third corner 323d, and fourth corner 323e). For example, each of the first housing 1031, the second housing 1032, and the third housing 1033 may include conductive side surfaces. At least one of the conductive side surfaces may be grounded to at least one support member of the first housing 1031, the second housing 1032, or the third housing 1033. The surface current may be induced on at least one of the conductive side surfaces as a portion of the first housing 1031, the second housing 1032, or the third housing 1033. A direction of the surface current induced on at least one of the conductive side surfaces may be the same as a direction of the surface current induced to the first housing 1031 or a direction of the surface current induced to at least one of the second housing 1032 and the third housing 1033. The surface current induced on the surface of the electronic device 3100 in the folded state may cause the first parasitic resonance. The first parasitic resonance may be referred to as PPW resonance.


In the electronic device 3100 in the folded state, when at least one of the conductive side surfaces is grounded to at least one support member of the first housing 1031, the second housing 1032, or the third housing 1033, the direction of the surface current (e.g., first surface current J1) induced on the surface of the electronic device 3100 and the direction of the surface current (e.g., second surface current J2) induced on the grounded at least one conductive side surface may be opposite to each other. The surface current (e.g., second surface current J2) induced on the grounded at least one conductive side surface may cause the second parasitic resonance. The second parasitic resonance may shift the frequency band of the first parasitic resonance. For example, the second parasitic resonance may cause the resonance-splitting phenomenon with respect to the first parasitic resonance.



FIG. 31D is a graph 1220 showing a frequency of the first parasitic resonance formed by the surface current of the electronic device 3100 in the folded state, according to various embodiments.


With reference to FIG. 31D, the X-axis may represent a frequency band (MHz) and the Y-axis may represent a reflection coefficient (dB) of a mode of electric field formed in the electronic device 3100 in the folded state. A first graph 1221 represents a frequency of the first parasitic resonance formed by the surface current induced on the surface of the Z-type foldable terminal 3100 in the folded state. In the electronic device 3100 in the folded state, according to the present disclosure, when at least one of the conductive side surfaces is grounded to at least one support member 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 the resonance-splitting phenomenon. For example, the first graph 1211 may shift to a frequency band that does not overlap a frequency band of a transmission signal from the radiator of the electronic device 3100. Therefore, communication performance and efficiency of the electronic device 3100 may be improved.



FIG. 32A is a conceptual diagram illustrating the electronic device 3200, according to various embodiments.



FIG. 32B is a conceptual diagram illustrating one side surface of the electronic device 3200, according to various embodiments.


With reference to FIGS. 32A and 32B, the electronic device 3200 may include and/or may be similar in many respects to the electronic device 101 of FIG. 1 and the electronic device 300 of FIGS. 2A to 29B, and may include additional features not mentioned 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 configured to couple with one side surface of the first housing 1051, and a second housing 1052 configured to couple with one side surface of the hinge structure 1061. In the electronic device 3200 based on the X-Y plane, the hinge structure 1061 may be aligned in the X-axis direction. Therefore, the first housing 1051 or the second housing 1052 may be folded in the Y-axis direction using the hinge structure 1061 aligned in the X-axis direction as the central axis. For example, the electronic device 3200 may be folded so that the first surface of the first housing 1051 and the second surface of the second housing 1052 face each other using the hinge structure 1061 as the central axis.



FIG. 32C is a conceptual diagram illustrating distribution of the surface current induced on the surface of the electronic device 3200 in the folded state, according to various embodiments.


With reference to FIG. 32C, in the electronic device 3200, when the first surface of the first housing 1051 and the first surface of the second housing 1052 are folded to face each other using the hinge structure 1061 as the central axis, the first housing 1051, the hinge structure 1061, and the second housing 1052 may be electrically coupled.


For example, the first housing 1051, the hinge structure 1061, and the second housing 1052 of the electronic device 3200 in the folded state may become equivalent to the form of a shielded parallel plate. Since the electric field (E-Field) of the electronic device 3200 in the folded state is proportional to potential, the potential may be zero (0) in the hinge structure 1061 to which the first housing 1051 and the second housing 1052 are grounded and magnitude of the electric field may be zero (0) accordingly. Alternatively, in the electronic device 3200 in the folded state, since the potential increases as a distance away from the hinge structure 1061 increases, the magnitude of the electric field may also increase.


The surface current induced on the surface of the electronic device 3200 in the folded state may flow from the hinge structure 1061 into one side surface of the first housing 1051, from one side surface of the first housing 1051 into the other side surface of the first housing 1051, from the other side surface of the first housing 1051 into the other side surface of the second housing 1052, from the other side surface of the second housing 1052 into the one side surface of the second housing 1052, and from one side surface of the second housing 1052 back into the hinge structure 1061 in a circulative manner.


In an embodiment, the electronic device 3200 may be and/or may include a foldable terminal having conductive side surfaces or metal frames (e.g., first side surface 313a, second side surface 313b, third side surface 313c, first corner 313d, second corner 313e, fourth side surface 323a, fifth side surface 323b, sixth side surface 323c, third corner 323d, and fourth corner 323e). For example, each of the first housing 1051 and the second housing 1052 may include conductive side surfaces. The surface current may be induced on at least one of the conductive side surfaces as a portion of at least one of the first housing 1051 and the second housing 1052. A direction of the surface current induced on at least one of the conductive side surfaces may be the same as a direction of the surface current induced to the first housing 1051 or a direction of the surface current induced to the second housing 1052. The surface current induced to the first housing 1051 or the second housing 1052 may cause the first parasitic resonance. At least one of the conductive side surfaces may be grounded to at least one support member of the first housing 1051 or the second housing 1052. When at least one of the conductive side surfaces is grounded to at least one support member of the first housing 1051 or the second housing 1052, the surface current (e.g., second surface current J2) that flows in a direction opposite to that of the surface current (e.g., first surface current J1) induced to the first housing 1051 or the second housing 1052 may be induced on the surface of the grounded conductive side. The surface current induced on the surface of the grounded conductive side surface may cause the second parasitic resonance. The second parasitic resonance may shift the frequency band of the first parasitic resonance. For example, the resonance-splitting phenomenon may occur between a frequency of the second parasitic resonance and a frequency of the first parasitic resonance.



FIG. 32D is a graph 1230 showing a frequency 1231 of the first parasitic resonance formed by the surface current induced on the surface of the electronic device 3200 in the folded state, according to various embodiments.


With reference to FIG. 32D, the X-axis may represent a frequency band (MHz) and the Y-axis may represent a reflection coefficient (dB) of a mode of electric field formed in the electronic device 3200 in the folded state. A first graph 1231 represents a frequency of the first parasitic resonance formed by the surface current induced on the surface of the wide foldable terminal 3200 in the folded state. In the electronic device 3200 in the folded state, according to the present disclosure, when at least one of the conductive side surfaces is grounded to at least one support member of the first housing 1051 or 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 a frequency band of a transmission signal from the radiator of the electronic device 3200. Therefore, communication performance and efficiency of the wide foldable terminal 3200 may be improved.
