[Technical Field]

[0001] The present invention relates to electronic devices that include antennas. [Background technology]

[0002] The use of electronic devices such as smartphones, foldable phones, or tablet PCs is increasing, and various functions are provided in the electronic devices.

[0003] The electronic devices transmit and receive telephone calls and various data to and from other electronic devices through wireless communication.

[0004] The electronic device includes at least one antenna for wireless communication with other electronic devices. Summary of the Invention [Problem to be solved by the invention]

[0005] The portable electronic device may be a bar type, a foldable type, a rollable type, a wearable type, or a tablet PC.

[0006] For example, a foldable electronic device operates by folding or unfolding multiple housings around a hinge module.

[0007] The foldable electronic device has a plurality of housings that form the exterior, at least a portion of which is made of a conductive material (e.g., metal), and at least a portion of the portion made of the conductive material is used as an antenna radiator for wireless communication. The plurality of housings includes at least one segment (e.g., a slit).

[0008] When multiple housings of a foldable electronic device are folded, a segment formed on the side of one housing is adjacent to a part of another housing made of a conductive material (e.g., a metal frame), reducing the antenna radiation performance.

[0009] In a foldable electronic device, when multiple housings are in a folded or unfolded state and a user grips a segment formed on a side of the housing with their fingers, the radiation performance of the antenna is reduced.

In some embodiments, at least one of these components (e.g., connection terminal 178) may be omitted or one or more other components may be added to electronic device 101. In some embodiments, some of these components (e.g., sensor module 176, camera module 180, or antenna module 197) may be integrated into a single component (e.g., display module 160).

[0019] The processor 120 executes software (e.g., program 140) to control at least one other component (e.g., a hardware or software component) of the electronic device 101 connected to the processor 120 and perform various data processing or calculations.

[0034] Communications module 190 supports establishing a direct (e.g., wired) or wireless communication channel between electronic device 101 and an external electronic device (e.g., electronic device 102, electronic device 104, or server 108) and performing communications over the established communication channel. Communications module 190 includes one or more communications processors that operate independently of processor 120 (e.g., an application processor) and support direct (e.g., wired) or wireless communications. According to one embodiment, communications module 190 includes wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication module). A corresponding one of these communication modules communicates with an external electronic device 104 through a first network 198 (e.g., a short-range communication network such as Bluetooth®, WiFi® (wireless fidelity) direct, or IrDA (infrared data association)) or a second network 199 (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various communication modules may be integrated into a single component (e.g., a single chip) or embodied as multiple separate components (e.g., multiple chips). The wireless communication module 192 identifies or authenticates the electronic device 101 within a communication network such as the first network 198 or the second network 199 using subscriber information (e.g., an International Mobile Subscriber Identity (IMSI)) stored in the subscriber identity module 196.

[0035] The wireless communication module 192 supports 5G networks and next-generation communication technologies beyond 4G networks, such as new radio access (NR) technology. NR technology supports high-speed transmission of large amounts of data (eMBB (enhanced mobile broadband)), minimizing terminal power consumption and connecting multiple terminals (mMTC (massive machine type communications)), or high-reliability and low-latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module 192 supports, for example, high-frequency bands (e.g., mmWave bands) to achieve high data rates. The wireless communication module 192 supports various technologies to ensure performance in high-frequency bands, such as beamforming, massive MIMO (multiple-input and multiple-output), full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, or large scale antennas.

[0048] According to one embodiment, the foldable electronic device 200 includes a flexible display 230 (e.g., a foldable display) disposed in a space formed by the first housing 210 and the second housing 220. For example, the flexible display 230 disposed in the space formed by the first housing 210 and the second housing 220 includes one display or at least two or more displays.

[0049] According to various embodiments, the first housing 210, in the unfolded state, includes a first surface 211 facing a first direction (e.g., front direction, z-axis direction) and a second surface 212 facing a second direction (e.g., rear direction, −z-axis direction) opposite to the first surface 211. According to one embodiment, the second housing 220, in the unfolded state, includes a third surface 221 facing the first direction (e.g., front direction, z-axis direction) and a fourth surface 222 facing the second direction (e.g., rear direction, −z-axis direction) opposite to the third surface 221.

[0050] According to one embodiment, the foldable electronic device 200 operates in such a manner that the first surface 211 of the first housing 210 and the third surface 221 of the second housing 220 face substantially in the same first direction (e.g., z-axis direction) in the unfolded state, and the first surface 211 of the first housing 210 and the third surface 221 of the second housing 220 face each other in the folded state. According to one embodiment, the foldable electronic device 200 operates in such a manner that the second surface 212 of the first housing 210 and the fourth surface 222 of the second housing 220 face substantially in the same second direction (e.g., rearward, −z-axis direction) in the unfolded state, and the second surface 212 of the first housing 210 and the fourth surface 222 of the second housing 220 face in opposite directions in the folded state. For example, when the foldable electronic device 200 is in a folded state, the second surface 212 of the first housing 210 faces in a second direction (e.g., rearward, -z-axis direction), and the fourth surface 222 of the second housing 220 faces in a first direction (e.g., forward, z-axis direction).

[0051] According to various embodiments, the first housing 210 and the second housing 220 are disposed on either side of the folding axis A and have substantially symmetrical shapes with respect to the folding axis A. The angle or distance between the first housing 210 and the second housing 220 changes depending on whether the foldable electronic device 200 is in an unfolded state, a folded state, or an intermediate state.

[0052] According to various embodiments, the first housing 210 and the second housing 220 have asymmetric shapes based on the folding axis A. For example, when the foldable electronic device 200 is in a folded state, the first housing 210 and the second housing 220 are folded in an asymmetric shape around the folding axis A so that a portion of the flexible display 230 is exposed to the outside of the foldable electronic device 200.

[0053] According to one embodiment, the first housing 210 includes a first side member 202 that at least partially forms the exterior of the foldable electronic device 200, and a first rear cover (not shown) that is coupled to the first side member 202 and forms at least a part of the second side 212 of the foldable electronic device 200. For example, the first side member 202 includes a first side 210a that is arranged parallel to the folding axis (A), a second side 210b that extends from one end of the first side 210a in a direction substantially perpendicular to the folding axis (A), and a third side 210c that extends from the other end of the first side 210a in a direction substantially perpendicular to the folding axis (A).

[0054] According to one embodiment, the second housing 220 includes a second side member 204 that at least partially forms the exterior of the foldable electronic device 200, and a second rear cover (not shown) that is coupled to the second side member 204 and forms at least a part of a fourth side 222 of the foldable electronic device 200. For example, the second side member 204 includes a fourth side 220a that is disposed substantially parallel to the folding axis (A), a fifth side 220b that extends from one end of the fourth side 220a in a direction substantially perpendicular to the folding axis (A), and a sixth side 220c that extends from the other end of the fourth side 220a in a direction substantially perpendicular to the folding axis (A).

[0055] According to one embodiment, the first side surface 210a of the first side surface member 202 includes a first segment 215. For example, the first segment 215 separates a portion of the first side surface 210a. The second side surface 210b of the first side surface member 202 includes a second segment 225. For example, the second segment 225 separates a portion of the second side surface 210b. The fifth side surface 220b of the second side surface member 204 includes a third segment 235. For example, the third segment 235 separates a portion of the fifth side surface 220b. For example, the first segment 215, the second segment 225, and / or the third segment 235 are formed in the form of a slit.

[0056] According to various embodiments, the first segment portion 215, the second segment portion 225, and / or the third segment portion 235 are filled with a non-conductive material. The non-conductive material prevents foreign matter from entering the inside of the foldable electronic device 200. The non-conductive material may include a dielectric (e.g., an insulator) including at least one of polycarbonate, polyimide, plastic, polymer, or ceramic, for example.

[0057] According to one embodiment, the second segment portion 225 formed on the second side surface 210b and the third segment portion 235 formed on the fifth side surface 220b are formed on a first side (e.g., the left side) and a second side (e.g., the right side) based on the hinge module 201. When the foldable electronic device 200 is in a folded state (e.g., FIG. 2b), the second segment portion 225 and the third segment portion 235 are arranged to overlap when viewed from above the second rear cover (not shown). The overlapping second segment portion 225 and the third segment portion 235 reduce degradation of the radiation performance of the antenna 240.

[0058] According to one embodiment, a portion of the first side surface 210a separated by the first segment 215 and a portion of the second side surface 210b separated by the second segment 225 act as antenna radiators and are electrically connected to a processor 120 (e.g., processor 120 of FIG. 1) or a communication module (e.g., communication module 190 of FIG. 1) in the foldable electronic device 200 to form the antenna 240. For example, the portion of the first side surface 210a and the portion of the second side surface 210b may be a single conductive portion (e.g., a radiator of the antenna 240) extending from the first segment 215 to the second segment 225. At least a portion of the conductive portion acts as a radiator of the antenna 240.

[0059] For example, antenna 240 operates in the low band (e.g., approximately 600 MHz to 1200 MHz), mid band (e.g., approximately 1500 MHz to 2200 MHz), and high band (e.g., approximately 2300 MHz to 2700 MHz) frequency bands. The frequency bands of antenna 240 are not limited to the above examples, and antenna 240 may transmit and receive signals in other frequency bands.

[0060] According to one embodiment, the antenna 240 includes a feed section 250f coupled to a feed point 250 located on the second side 210b, a first matching circuit (S1) coupled to a first point 251 located between the feed point 250 and the first segment 215, and a second matching circuit (S2) coupled to a second point 252 located between the feed point 250 and the second segment 225.

[0061] For example, the first matching circuit (S1) includes a first switch (e.g., switch 1310 in FIG. 13) and / or at least one lumped element (e.g., passive element 1320 in FIG. 13). The second matching circuit (S2) includes a second switch (e.g., switch 1310 in FIG. 13) and / or at least one lumped element (e.g., passive element 1320 in FIG. 13). The at least one lumped element includes a capacitor or an inductor. The power supply unit 250f is disposed between the first matching circuit (S1) and the second matching circuit (S2).

[0062] According to various embodiments, the power feed portion 250f is coupled to the power feed point 250 located on the second side surface 210b. The power feed portion 250f is electrically coupled to the processor 120 (or the communication module 190). The power feed portion 250f supports the antenna 240 to transmit and receive wireless signals. The power feed portion 250f is coupled to the power feed point 250 via, for example, a C-clip. The power feed portion 250f supplies power to the antenna 240.

[0063] According to various embodiments, the first matching circuit (S1) and the second matching circuit (S2) adjust the electrical length of the antenna 240 using a first switch, a second switch, or at least one lumped element.

[0064] According to various embodiments, the first matching circuit (S1) is coupled to a first point 251 that is closer to the first side 210a than the feed point 250. For example, the first point 251 is disposed on one side (e.g., the left side, in the -x-axis direction) of the feed portion 250f. In one embodiment, the first point 251 is disposed adjacent to a first segment 215 formed on the first side 210a. The first matching circuit (S1) is electrically coupled to the processor 120 or the communication module 190. In one embodiment, the first point 251 is disposed at a distance of about λ / 4 or more from the first segment 215 in the low band. In one embodiment, the first matching circuit (S1) selectively electrically couples a conductive portion (e.g., the antenna 240) to ground (G). In one embodiment, the first switch of the first matching circuit (S1) is used as a shunt element of the tuner. According to one embodiment, the first matching circuit (S1) has its matching value adjusted under the control of the processor 120 or the communication module 190.

[0065] According to various embodiments, the processor 120 (or the communication module 190) controls the first switch included in the first matching circuit (S1) to be turned on and the second switch included in the second matching circuit (S2) to be in an isolation mode (e.g., open state), thereby adjusting the electrical path of the antenna 240. For example, when the first switch included in the first matching circuit (S1) is turned on and the conductive portion (e.g., the antenna 240) is connected to the ground (G) at the first point 251, the antenna 240 uses the second region 242, which is the conductive portion between the first point 251 and the second segment 225, as the main radiation region. For example, the portion of the second side surface 210b in contact with the second segment 225 becomes the main radiation region.

[0066] According to various embodiments, the second matching circuit (S2) is coupled to a second point 252 that is farther from the first side 210a than the feed point 250. For example, the second point 252 is disposed on the other side (e.g., the right side) of the feed portion 250f. In one embodiment, the second point 252 is disposed adjacent to the second segment 225 formed on the second side 220b. The second matching circuit (S2) is electrically coupled to the processor 120 (or the communication module 190). In one embodiment, the second point 252 is disposed at a distance of about λ / 4 or more from the second segment 225 in the low band. The second matching circuit (S2) selectively electrically couples a conductive portion (e.g., a portion of the antenna 240) to ground (G) using a second switch included in the second matching circuit (S2). In one embodiment, the second switch is used as a shunt element of the tuner. The matching value of the second matching circuit (S2) is adjusted under the control of the processor 120 (or the communication module 190).

[0067] According to various embodiments, the processor 120 or the communication module 190 controls the second switch included in the second matching circuit (S2) to be turned on and the first switch included in the first matching circuit (S1) to be in an isolation mode (e.g., open state), thereby adjusting the electrical path of the antenna 240. For example, when the second switch included in the second matching circuit (S2) is turned on and the conductive portion (e.g., the antenna 240) is connected to the ground (G) at the second point 252, the antenna 240 uses the first region 241, which is the conductive portion between the second point 252 and the first segment 215, as the main radiation region. For example, the portions of the first side surface 210a and the second side surface 210b in contact with the first segment 215 become the main radiation region.

[0068] According to various embodiments, the first matching circuit (S1) includes a first switch, a first lumped element, or a second lumped element. The second matching circuit (S2) includes a second switch, a third lumped element, or a fourth lumped element. For example, the first lumped element and the third lumped element have higher L values ​​than the second lumped element and the fourth lumped element. The first matching circuit (S1) electrically connects a first point 251 of the conductive portion (e.g., antenna 240) to ground (G). The second matching circuit (S2) electrically connects a second point 252 of the conductive portion (e.g., antenna 240) to ground (G).

[0069] In one embodiment, the processor 120 (or the communication module 190) connects a first switch included in the first matching circuit (S1) to the first lumped element and electrically connects it to ground (G), and connects a second switch included in the second matching circuit (S2) to the fourth lumped element and electrically connects it to ground (G), thereby controlling the portion of the antenna 240 in contact with the first segment 215 (e.g., the first region 241) to be the main radiation region. In another example, the processor 120 (or the communication module 190) connects a first switch included in the first matching circuit (S1) to the second lumped element and electrically connects it to ground (G), and connects a second switch included in the second matching circuit (S2) to the third lumped element and electrically connects it to ground (G), thereby controlling the portion of the antenna 240 in contact with the second segment 225 (e.g., the second region 242) to be the main radiation region.

[0070] According to various embodiments, the first matching circuit (S1) and the second matching circuit (S2) convert the frequency band of the antenna 240 by adjusting the matching values ​​through the processor 120 (or the communication module 190).

[0071] According to one embodiment, the antenna 240 uses the first region 241, which is the conductive portion between the first segment 215 and the second point 252, as the main radiation region by adjusting the matching values ​​of the first matching circuit (S1) and the second matching circuit (S2), or uses the second region 242, which is the conductive portion between the first point 251 and the second segment 225, as the main radiation region.

[0072] For example, when the foldable electronic device 200 is in a folded state (e.g., FIG. 2b), if the first segment 215 formed on the first side 210a of the first housing 210 is adjacent to or overlaps the fourth side 220a of the second housing 220 made of a conductive material, the radiation performance of the antenna 240 will be reduced. In this case, the processor 120 (or the communication module 190) turns on the first matching circuit (S1) to adjust the electrical path of the antenna 240, thereby transmitting and receiving wireless signals using the second region 242, which is a conductive portion between the first point 251 and the second segment 225, as the main radiation region.

[0073] According to various embodiments, when the foldable electronic device 200 is in an unfolded state (e.g., FIG. 2a) or a folded state (e.g., FIG. 2b), if the first segment 215 formed on the first side 210a of the first housing 210 is gripped by a user's fingers, the radiation performance of the antenna 240 is reduced. In this case, the processor 120 (or the communication module 190) turns on the first matching circuit (S1) to adjust the electrical path of the antenna 240, thereby transmitting and receiving wireless signals using the second region 242, which is a conductive portion between the first point 251 and the second segment 225, as a main radiation region.

[0074] According to various embodiments, the foldable electronic device 200 includes a recess (not shown) formed to accommodate the flexible display 230 through structural coupling of the first housing 210 (e.g., the first side member 202) and the second housing 220 (e.g., the second side member 204). The foldable electronic device 200 includes a printed circuit board (not shown) inside the first housing 210 and / or the second housing 220. The processor 120, memory 130, input module 150, acoustic output module 155, audio module 170, sensor module 176, haptic module 179, camera module 180, communication module 190, and / or communication module 190 shown in FIG. 1 are arranged on the printed circuit board. According to one embodiment, at least a portion of the first housing 210 and the second housing 220 is formed of a metallic or non-metallic material to support the flexible display 230.

[0075] According to various embodiments, the foldable electronic device 200 may be an in-folding type electronic device in which the flexible displays 230 are folded inward to face each other so that the flexible displays 230 are not substantially exposed to the outside of the foldable electronic device 200 in the folded state (e.g., FIG. 2b). In another embodiment (not shown), the foldable electronic device 200 may be an out-folding type electronic device in which the flexible displays 230 are folded outward so that the flexible displays 230 are visually exposed to the outside of the foldable electronic device 200 in the folded state. In another embodiment (not shown), the foldable electronic device 200 may be a multi-folding type foldable electronic device in which the in-folding method and the out-folding method are combined.

[0076] 3a is a diagram schematically illustrating another example of an unfolded state of a foldable electronic device according to various embodiments of the present invention, and FIG. 3b is a diagram schematically illustrating another example of a folded state of a foldable electronic device according to various embodiments of the present invention.

[0077] In the description of Figures 3a and 3b, the same reference numerals are used for the same components as those in Figures 2a and 2b described above, and redundant descriptions of their functions and arrangements will be omitted. The foldable electronic device 200 in Figures 3a and 3b includes the electronic device 101 in Figure 1 and the foldable electronic device 200 in Figures 2a and 2b.

[0078] In the following description of FIGS. 3a and 3b, differences from the embodiment of FIGS. 2a and 2b will be described.

[0079] 3a and 3b, the foldable electronic device 200 according to various embodiments of the present invention includes a fourth segment 315 on the fourth side surface 220a of the second housing 220. The fourth segment 315 separates a portion of the fourth side surface 220a. The fourth segment 315 is formed in the form of a slit. The fourth segment 315 is filled with a non-conductive material (e.g., an insulator).

[0080] According to an embodiment, the fourth segment 315 is formed at a position corresponding to the first segment 215 formed on the first side surface 210a of the first housing 210 with respect to the folding axis (A).

[0081] According to one embodiment, when the foldable electronic device 200 is in a folded state (e.g., FIG. 3b), the first segment 215 and the fourth segment 315 are arranged to overlap when viewed from above the second rear cover (not shown). The overlapping second segment 225 and the third segment 235 reduce degradation of the radiation performance of the antenna 240.

[0082] Fig. 4 is a diagram illustrating the operation of an antenna of a foldable electronic device according to various embodiments of the present invention. Fig. 5 is a diagram illustrating an electric field when an antenna of a foldable electronic device according to various embodiments of the present invention radiates through a first region between a first segment and a second point and a second region between the first point and the second segment. Fig. 6 is a diagram illustrating an electric field when an antenna of a foldable electronic device according to various embodiments of the present invention uses the second region between the first point and the second segment as a main radiation region. Fig. 7 is a diagram illustrating an electric field when an antenna of a foldable electronic device according to various embodiments of the present invention uses the first region between the first segment and the second point as a main radiation region. Fig. 8 is a diagram illustrating an antenna of a foldable electronic device according to various embodiments of the present invention radiating through the first region between the first segment and the second point and the second region between the first point and the second segment.

[0083] In the description of FIGS. 4 to 8, the same reference numerals are given to the same components as those in FIGS. 2a, 2b, 3a, and 3b described above, and redundant descriptions of their functions and arrangements will be omitted.

[0084] 4, the antenna 240 of the foldable electronic device 200 according to various embodiments of the present invention includes a power supply unit 250f, a first matching circuit (S1), and a second matching circuit (S2). According to one embodiment, the first matching circuit (S1) and the second matching circuit (S2) provided on one side and the other side of the power supply unit 250f adjust the electrical length of the antenna 240 by on / off operation. The matching values ​​of the first matching circuit (S1) and the second matching circuit (S2) are adjusted through the processor 120 (or the communication module 190), so that the antenna 240 uses the first region 241, which is the conductive portion between the first segment 215 and the second point 252, as the main radiation region, or the second region 242, which is the conductive portion between the first point 251 and the second segment 225, as the main radiation region. The antenna 240 operates in, for example, a low band (for example, approximately 600 MHz to 1200 MHz) frequency band by adjusting the matching values ​​of the first matching circuit (S1) and the second matching circuit (S2).

[0085] According to various embodiments, the antenna 240 of the foldable electronic device 200 radiates wireless signals through a first region 241 between the first segment 215 and the second point 252 and a second region 242 between the first point 251 and the second segment 225.

[0086] 5, it is possible to see the electric field when the antenna 240 of the foldable electronic device 200 radiates through the first region 241 between the first segment 215 and the second point 252 and the second region 242 between the first point 251 and the second segment 225. The electric field in Fig. 5 shows the electric field of the first segment 215 and the second segment 225 when the first segment 215 and the fourth segment 315 are vertically aligned and the second segment 225 and the third segment 235 are vertically aligned when the foldable electronic device 200 is in a folded state (e.g., Fig. 3b).

[0087] According to various embodiments, when the foldable electronic device 200 is in a folded state (e.g., FIG. 2b), if the first segment 215 formed on the first side surface 210a of the first housing 210 overlaps with the fourth side surface 220a of the second housing 220 made of a conductive material, the radiation performance of the antenna 240 will be reduced. In this case, the processor 120 (or the communication module 190) adjusts the matching values ​​of the first matching circuit (S1) and the second matching circuit (S2) to select one of the first region 241 between the first segment 215 and the second point 241 of the antenna 240 or the second region 242 between the first point 251 and the second segment 225 as the main radiation region. For example, the processor 120 (or the communication module 190) turns on the first matching circuit (S1) and operates the second matching circuit (S2) in an isolation mode (e.g., open state), and adjusts the electrical path of the antenna 240 to a first length (L), thereby using the second region 242 between the first point 251 and the second segment 225 as the main radiation region. In another example, impedance matching is performed using at least one lumped element included in the first matching circuit (S1) according to the frequency band supported by the antenna 240.

[0088] The electric field in Figure 6 shows the electric field of the second segment 225 when the foldable electronic device 200 is in a folded state (e.g., Figure 2b), the fourth side 220a of the second housing 220, which is made of a conductive material, is adjacent to or overlaps the top of the first segment 215, and the second segment 225 and the third segment 235 are aligned vertically.

[0089] 6, the electric field when the antenna 240 of the foldable electronic device 200 radiates using the second region 242 between the first point 251 and the second segment 225 as the main radiation region can be seen. For example, the first matching circuit (S1) operates substantially the same as when a first switch included in the first matching circuit (S1) is connected to an inductor having 1 nH and the first switch is shorted, and the second matching circuit (S2) operates substantially the same as when a second switch included in the second matching circuit (S2) is connected to an inductor having 56 nH and the second switch is open. In this case, the antenna 240 uses the second region 242 between the first point 251 and the second segment 225 as the main radiation region.

[0090] 8, the antenna 240 of the foldable electronic device 200 operates in a low band (e.g., about 600 MHz to 1200 MHz) frequency band. For example, the antenna 240 operates in a frequency band of about 0.85 GHz to 0.9 GHz through a first region 241 between a first segment 215 and a second point 252, and operates in a frequency band of about 1.15 GHz to 1.2 GHz through a second region 242 between the first point 251 and a second segment 225. For example, as shown in FIG. 4, the antenna 240 operates at a frequency resonance corresponding to a second length (L2) that is an electrical path of the first region 241 formed between the first segment 215 and the second point 252 and a first length (L1) that is an electrical path of the second region 242 formed between the first point 251 and the second segment 225. According to various embodiments, when the foldable electronic device 200 is in an unfolded state (e.g., FIGS. 2a and 3a) or a folded state (e.g., FIGS. 2b and 3b), if the second segment 225 formed on the second side surface 210b of the first housing 210 is held by the palm or fingers of a user, the radiation performance of the antenna 240 decreases. In this case, the processor 120 (or the communication module 190) adjusts the matching values ​​of the first matching circuit (S1) and the second matching circuit (S2) to select one of the first region 241 between the first segment 215 and the second point 252 or the second region 242 between the first point 251 and the second segment 225 as the main radiation region. For example, the processor 120 (or the communication module 190) turns on the second matching circuit (S2) and operates the first matching circuit (S1) in an isolation mode (e.g., in an open state), and adjusts the electrical path of the antenna 240 by a second length (L2), thereby using the first region 241 between the first segment 215 and the second point 252 as the main radiation region.

[0091] 4, in various embodiments, antenna 240 operates at a first resonant frequency using a first length (L1) that is an electrical path formed between first point 251 and second region 242 between second segment 225. Antenna 240 operates at a second resonant frequency using a second length (L2) that is an electrical path formed between first region 241 between first segment 215 and second point 252.

[0092] The electric field in Figure 7 shows the electric field of the first segment 215 when the second segment 225 formed on the second side 210b of the first housing 210 is grasped by the palm or fingers of the user when the foldable electronic device 200 is in an unfolded state (e.g., Figures 2a and 3a) or a folded state (e.g., Figures 2b and 3b).

[0093] 7, the electric field when the antenna 240 of the foldable electronic device 200 radiates using the first region 241 between the first segment 215 and the second point 252 as the main radiation region, as described with reference to FIG. 4, can be seen. For example, the first matching circuit (S1) operates substantially the same as when a first switch included in the first matching circuit (S1) is connected to an inductor having a resistance of 56 nH and the first switch is open, and the second matching circuit (S2) operates substantially the same as when a second switch included in the second matching circuit (S2) is connected to an inductor having a resistance of 1 nH and the second switch is shorted. In this case, the antenna 240 uses the first region 241 between the first segment 215 and the second point 252 as the main radiation region.

[0094] 9 is a diagram illustrating an operation of adjusting the matching values ​​of the third matching circuit (S3) and the fourth matching circuit (S4) of the antenna of the foldable electronic device according to various embodiments of the present invention. FIG. 10 is a diagram illustrating S-parameters illustrating a change in frequency band through switching of the third matching circuit (S3) and the fourth matching circuit (S4) of the antenna of the foldable electronic device according to various embodiments of the present invention.

[0095] In the description of FIG. 9, the same components as those in FIG. 4 are given substantially the same reference numerals, and redundant descriptions of their functions and arrangements will be omitted.

[0096] 9, the antenna 240 of the foldable electronic device 200 according to various embodiments of the present invention includes a power supply unit 250f, a first matching circuit (S1), and a second matching circuit (S2). The first matching circuit (S1) and the second matching circuit (S2) provided on one side and the other side of the power supply unit 250f adjust the electrical length of the antenna 240 by on / off operation. The matching values ​​of the first matching circuit (S1) and the second matching circuit (S2)2 are adjusted through the processor 120 (or the communication module 190). The antenna 240 uses the first region 241, which is the conductive portion between the first segment 215 and the second point 252, as the main radiation region, or selects the second region 242, which is the conductive portion between the first point 251 and the second segment 225, as the main radiation region. The antenna 240 operates in, for example, a low band (for example, about 600 MHz to 1200 MHz) frequency band by adjusting the matching values ​​of the first matching circuit (S1) and the second matching circuit (S2). The antenna 240 of the foldable electronic device 200 radiates a wireless signal through a first region 241 between the first segment 215 and the second point 252, and a second region 242 between the first point 251 and the second segment 225. According to one embodiment, the power supply unit 250f, the first matching circuit (S1), and the second matching circuit (S22) are located between the first segment 215 and the second segment 225.

[0097] According to one embodiment, the feed unit 250f is disposed between the first matching circuit (S1) and the second matching circuit (S2). The feed unit 250f is coupled to a feed point 250 located on the second side surface 210b. The first matching circuit (S1) is coupled to a first point 251 that is closer to the first side surface 210 than the feed point 250. In one embodiment, the first point 251 is disposed adjacent to the first segment 215 formed on the first side surface 210a. The second matching circuit (S2) is coupled to a second point 252 that is farther from the first side surface 210a than the feed point 250. In one embodiment, the second point 252 is disposed closer to the second segment 225 formed on the second side surface 220b than the first segment 215 formed on the first side surface 210a.

[0098] According to various embodiments, a third matching circuit S3 is located on the first side 210a, which is opposite the first matching circuit S1 with respect to the first segment 215. The third matching circuit S3 is connected to a third point 930 located on the first side 210a, which is opposite the first point 251 with respect to the first segment 215. For example, the first segment 215 is located between the first point 251 and the third point 930. A fourth matching circuit S4 is located on the second side 210b, which is opposite the second matching circuit S2 with respect to the second segment 225. The fourth matching circuit S4 is connected to a fourth point 940 located on the second side 210b, which is opposite the second point 252 with respect to the second segment 225. For example, the second segment 225 is located between the second point 252 and the fourth point 940.

[0099] According to various embodiments, the third matching circuit (S3) and the fourth matching circuit (S4) are electrically coupled to the processor 120 (or the communication module 190). The antenna 240 is switched to operate in a frequency band, for example, mid band (e.g., about 1500 MHz to 2200 MHz) and / or high band (e.g., about 2300 MHz to 2700 MHz), by adjusting the matching values ​​of the third matching circuit (S3) and the fourth matching circuit (S4) through the processor 120 (or the communication module 190).

[0100] 10, the antenna 240 adjusts the matching value of the third matching circuit (S3) to, for example, switch from a high band frequency band of about 2.6 GHz to 2.62 GHz to a mid band frequency band of about 1.75 GHz to 1.8 GHz. The antenna 240 adjusts the matching value of the fourth matching circuit (S4) to, for example, switch from a high band frequency band of about 2.65 GHz to 2.7 GHz to a high band frequency band of about 2.35 GHz to 2.4 GHz. In this case, it can be confirmed that even if the frequency band of the antenna 240 is switched to the mid band and / or high band through adjustment of the matching values ​​of the third matching circuit (S3) and the fourth matching circuit (S4), the low band (e.g., about 0.6 GHz to 0.8 GHz) frequency band due to adjustment of the matching values ​​of the first matching circuit (S1) and the second matching circuit (S2) is not affected.

[0101] According to various embodiments, the third matching circuit (S3) includes a third switch (e.g., switch 1310 in FIG. 13) and / or at least one lumped element (e.g., passive element 1320 in FIG. 13). The fourth matching circuit (S4) includes a fourth switch (e.g., switch 1310 in FIG. 13) and / or at least one lumped element (e.g., passive element 1320 in FIG. 13). For example, the at least one lumped element includes a capacitor or an inductor.

In the description of Figures 11a and 11b, the same reference numerals are used for components that are substantially the same as those in the above-mentioned Figures 2a to 10, and redundant description of their functions and operations will be omitted.

[0106] According to one embodiment, the first housing 210 and the second housing 1120 are rotatably coupled around a first folding axis (A) via a hinge module 201. The first housing 210 and the second housing 1120 are folded in an in-folding manner so that the flexible display 230 is not visually exposed to the outside of the multi-foldable electronic device 1100 in a folded state (e.g., FIG. 11b). When the first housing 210 and the second housing 1120 are folded in an in-folding manner, the flexible displays 230 disposed in the first housing 210 and the second housing 1120 are folded inward to face each other.

[0107] According to one embodiment, the second housing 1120 and the third housing 1130 are coupled to each other so as to be rotatable about a second folding axis (B) via a folding portion 1101. The second housing 1120 and the third housing 1130 are folded in an out-folding manner so that the flexible display 230 is visually exposed to the outside of the multi-foldable electronic device 1100 in the folded state (e.g., FIG. 11b). When the second housing 1120 and the third housing 1130 are folded in an out-folding manner, the flexible displays 230 disposed in the second housing 1120 and the third housing 1130 are folded outward so as not to face each other.

[0108] According to various embodiments, when the multi-foldable electronic device 1100 is in an unfolded state (e.g., FIG. 11a), the first housing 210, the second housing 1120, and the third housing 1130 are substantially planar and form an angle of approximately 180°. When the multi-foldable electronic device 1100 is in a folded state (e.g., FIG. 11b), the first housing 210, the second housing 1120, and the third housing 1130 are arranged to overlap each other.

[0109] According to one embodiment, the multi-foldable electronic device 1100 includes a flexible display 230 (e.g., a foldable display) disposed in a space formed by the first housing 210, the second housing 1120, and the third housing 1130. In one embodiment, the flexible display 230 disposed in the space formed by the first housing 210, the second housing 1120, and the third housing 1130 includes one display or at least two or more displays.

[0110] According to various embodiments, the first housing 210, in its unfolded state, includes a first surface 211 facing a first direction (e.g., the front direction, the z-axis direction) and a second surface 212 facing a second direction (e.g., the rear direction, the -z-axis direction) opposite to the first surface 211. According to one embodiment, the second housing 1120, in its unfolded state, includes a third surface 1121 facing the first direction (e.g., the front direction, the z-axis direction) and a fourth surface 1122 facing a second direction (e.g., the rear direction, the -z-axis direction) opposite to the third surface 1121. According to one embodiment, the third housing 1130, in its unfolded state, includes a fifth surface 1131 facing the first direction (e.g., the front direction, the z-axis direction) and a sixth surface 1132 facing a second direction (e.g., the rear direction, the -z-axis direction) opposite to the fifth surface 1131.

[0111] According to one embodiment, in the unfolded state, the first face 211 of the first housing 210, the third face 1121 of the second housing 1120, and the fifth face 1131 of the third housing 1130 face in substantially the same first direction (e.g., the front direction, z-axis direction) of the multi-foldable electronic device 1100. In the folded state, the multi-foldable electronic device 1100 operates in such a manner that the first face 211 of the first housing 210 and the third face 1121 of the second housing 1120 face each other, and the fourth face 1122 of the second housing 1120 and the sixth face 1132 of the third housing 1130 face each other.

[0112] According to various embodiments, the multi-foldable electronic device 1100 includes a first surface (e.g., a facing or front surface) on which the flexible display 230 is disposed, a second surface (e.g., a bottom or rear surface) opposite the first surface, and side surfaces surrounding the first and second surfaces.

[0113] According to one embodiment, the first housing 210 includes a first side member 202 that at least partially defines the exterior of the multi-foldable electronic device 1100. The second housing 1120 includes a second side member 1126 that at least partially defines the exterior of the multi-foldable electronic device 1100. The third housing 1130 includes a third side member 1136 that at least partially defines the exterior of the multi-foldable electronic device 1100.

[0114] In one embodiment, the first side member 210, the second side member 1126, and the third side member 1136 are formed using a conductive material (eg, metal).

[0115] According to various embodiments, the first housing 210 and the second housing 1120 are disposed on opposite sides of a first folding axis (A) and have substantially symmetrical shapes with respect to the first folding axis (A). The second housing 1120 and the third housing 1130 are disposed on opposite sides of a second folding axis (B) and have substantially symmetrical shapes with respect to the second folding axis (B).

[0116] According to various embodiments, the first housing 210 and the second housing 220 may have asymmetric shapes with respect to the first folding axis (A), and the second housing 1120 and the third housing 1130 may have asymmetric shapes with respect to the second folding axis (B).

[0117] According to one embodiment, the first housing 210 includes a first rear cover (not shown) coupled to the first side member 202 and forming at least a portion of the second side 212 of the multi-foldable electronic device 1100. For example, the first side member 202 includes a first side 210a disposed substantially parallel to the first folding axis (A), a second side 210b extending from one end of the first side 210a in a direction substantially perpendicular to the first folding axis (A), and a third side 210c extending from the other end of the first side 210a in a direction substantially perpendicular to the first folding axis (A).

[0118] According to one embodiment, the second housing 1120 includes a second rear cover (not shown) coupled to a second side member 1126 and forming at least a portion of a fourth side 1122 of the multi-foldable electronic device 1100. For example, the second side member 1126 includes a fourth side 1120b disposed substantially parallel to the second side 210b of the first side member 202 and a fifth side 1120c disposed substantially parallel to the third side 210c of the first side member 202.

[0119] According to one embodiment, the third housing 1130 includes a third rear cover (not shown) coupled to a third side member 1136 and forming at least a portion of a sixth side 1132 of the multi-foldable electronic device 1100. For example, the third side member 1136 includes a sixth side 1130a disposed substantially parallel to the second folding axis (B), a seventh side 1130b extending from one end of the sixth side 1130a toward the fourth side 1120b of the second side member 1126 in a direction substantially perpendicular to the second folding axis (B), and an eighth side 1130c extending from the other end of the sixth side 1130a toward the fifth side 1120c of the second side member 1126 in a direction substantially perpendicular to the second folding axis (B).

[0120] According to various embodiments, when the multi-foldable electronic device 1100 is in an unfolded state (e.g., FIG. 11a), the second side 210b of the first side member 202, the fourth side 1120b of the second side member 1126, and the seventh side 1130b of the third side member 1136 are arranged substantially parallel, and the third side 210c of the first side member 201, the fifth side 1120c of the second side member 1126, and the eighth side 1130c of the third side member 1136 are arranged substantially parallel.

[0121] According to one embodiment, the first side 210a of the first side member 202 includes a first segment 215. For example, the first segment 215 separates a portion of the first side 210a. The second side 210b of the first side member 202 includes a second segment 225. For example, the second segment 225 separates a portion of the second side 210b. The fourth side 1120b of the second side member 1126 includes a third segment 1125. For example, the third segment 1125 separates a portion of the fourth side 1120b. The seventh side 1130b of the third side member 1136 includes a fourth segment 1135. For example, the fourth segment 1135 separates a portion of the seventh side 1130b. The first segment 215, the second segment 225, the third segment 1125, and the fourth segment 1135 are each formed in the form of a slit.

[0122] According to one embodiment, the second segment 225 formed on the second side surface 210b and the third segment 1125 formed on the fourth side surface 1120b are disposed on a first side (e.g., left side) and a second side (e.g., right side) based on the hinge module 201. The third segment 1125 formed on the fourth side surface 1120b and the fourth segment 1135 formed on the seventh side surface 1130b are disposed on a first side (e.g., left side) and a second side (e.g., right side) based on the folding portion 1101.

[0123] According to one embodiment, when the multi-foldable electronic device 1100 is in a folded state (e.g., FIG. 11b), the second segment 225, the third segment 1125, and the fourth segment 1135 are arranged to be stacked one on top of the other when viewed from above the first surface. The stacked second segment 225, the third segment 1125, and the fourth segment 1135 reduce degradation of the radiation performance of the antenna 240.

[0124] According to one embodiment, a portion of the first side surface 210a separated by the first segment 215 and a portion of the second side surface 210b separated by the second segment 225 act as antenna radiators and are electrically connected to the processor 120 (or the communication module 190) in the multi-foldable electronic device 1100 to form the antenna 240. For example, a portion of the first side surface 210a and a portion of the second side surface 210b may be a single conductive portion (e.g., a radiator of the antenna 240) extending from the first segment 215 to the second segment 225. At least a portion of the conductive portion acts as a radiator of the antenna 240.

[0125] According to one embodiment, the antenna 240 includes a feed point 250f, a first matching circuit (S1), and a second matching circuit (S2). In one embodiment, the feed point 250, the first point 251, and the second point 252 are disposed on the second side 210b of the first housing 210.

[0126] According to various embodiments, the feed portion 250f is connected to a feed point 250 disposed on the second side surface 210b. The first matching circuit (S1) is connected to a first point 251 that is closer to the first side surface 210a than the feed point 250. For example, the first matching circuit (S1) is disposed on one side (e.g., the left side) of the feed portion 250f. In one embodiment, the first point 251 is disposed adjacent to the first segment 215 formed on the first side surface 210a. The second matching circuit (S2) is connected to a second point 252 that is farther from the first side surface 210a than the feed point 250. For example, the second point 252 is disposed on the other side (e.g., the right side) of the feed portion 250f. In one embodiment, the second point 252 is disposed adjacent to the second segment 225 formed on the second side surface 220b.

[0127] According to various embodiments, the first matching circuit (S1) and the second matching circuit (S2) convert the frequency band of the antenna 240 by adjusting the matching values ​​through the processor 120 (or the communication module 190). The antenna 240 uses the first region 241, which is the conductive portion between the first segment 215 and the second point 252, as the main radiation region, or the second region 242, which is the conductive portion between the first point 251 and the second segment 225, as the main radiation region by adjusting the matching values ​​of the first matching circuit (S1) and / or the second matching circuit (S2).

[0128] For example, when the multi-foldable electronic device 1100 is in a folded state (e.g., FIG. 11b), if the first segment 215 formed on the first side 210a of the first housing 210 is adjacent to or overlaps the display 230 disposed on at least a portion of the second housing 1120 and the third housing 1130, the radiation performance of the antenna 240 will be reduced. In this case, the processor 120 (or the communication module 190) turns on the first matching circuit (S1) to adjust the electrical path of the antenna 240, thereby transmitting and receiving wireless signals using the second region 242, which is the conductive portion between the first point 251 and the second segment 225, as the main radiation region.

[0129] According to various embodiments, when the multi-foldable electronic device 1100 is in an unfolded state (e.g., FIG. 11a) or a folded state (e.g., FIG. 11b), if the first segment 215 formed on the first side 210a of the first housing 210 is gripped by a user's fingers, the radiation performance of the antenna 240 decreases. In this case, the communication module 190 turns on the first matching circuit (S1) and turns off the second matching circuit (S2) to adjust the electrical path of the antenna 240, thereby transmitting and receiving wireless signals using the second region 242, which is a conductive portion between the first point 215 and the second segment 225, as the main radiation region. According to various embodiments, the multi-foldable electronic device 1100 includes a recess (not shown) formed to accommodate the flexible display 230 through structural coupling of the first housing 210 (e.g., first side member 202), the second housing 1120 (e.g., second side member 1126), and the third housing 1130 (e.g., third side member 1136). The multi-foldable electronic device 1100 includes a printed circuit board (not shown) inside at least one of the first housing 210, the second housing 1120, or the third housing 1130. The processor 120, memory 130, input module 150, acoustic output module 155, audio module 170, sensor module 176, haptic module 179, camera module 180, communication module 190, and / or the like shown in FIG. 1 are disposed on the printed circuit board. At least a portion of the first housing 210, the second housing 1120, and the third housing 1130 is made of a metallic or non-metallic material to support the flexible display 230.

[0130] Figure 12a is a diagram illustrating the operation of the antenna when the multi-foldable electronic device of Figure 11a is used in landscape mode, and Figure 12b is a diagram illustrating the operation of the antenna when the multi-foldable electronic device of Figure 11a is used in portrait mode.

[0131] 12a, when the multi-foldable electronic device 1100 according to various embodiments of the present invention is used in an unfolded state (e.g., landscape mode), the first segment 215 formed on the first side surface 210a of the first housing 210 is grasped by the user's finger 1210. In this case, as described with reference to FIG. 11a, the radiation performance of the antenna 240 is reduced through the first region 241, which is the conductive portion between the first segment 215 and the second point 252.

[0132] 4 and 11a, the processor 120 (or the communication module 190) turns on the first matching circuit (S1) to adjust the matching value, and operates the second matching circuit (S2) in an isolation mode (e.g., open state) to adjust the electrical path of the antenna 240. When the first matching circuit (S1) is turned on, the antenna 240 radiates by operating the second region 242, which is the conductive portion between the first point 251 and the second segment 225, as the main radiation region.

[0133] 12b, when the multi-foldable electronic device 1100 according to various embodiments of the present invention is used in an unfolded state (e.g., a vertical mode), the second segment 225 formed on the second side surface 210b of the first housing 210 is gripped by the user's finger 1210. In this case, the radiation performance of the antenna 240 through the second region 242, which is a conductive portion between the first point 251 and the second segment 225, is reduced.

[0134] 4 and 11a, the communication module 190 turns on the second matching circuit S2 to adjust the matching value, and operates the first matching circuit SW1 in an isolation mode (e.g., open state) to adjust the electrical path of the antenna 240. When the second matching circuit S2 is turned on, the antenna 240 radiates by operating the first region 241 between the first segment 215 and the second point 252 as the main radiation region.

[0135] According to various embodiments, the foldable electronic device 200 or the multi-foldable electronic device 1100 according to various embodiments of the present invention reduces degradation of antenna performance by selecting and using one of the first region 241, which is the conductive portion between the first segment 215 and the second point 252 formed on the antenna 240, or the second region 242, which is the conductive portion between the first point 251 and the second segment 225, as the main radiation region.

[0136] According to various embodiments, the above-described embodiments have been described using the foldable electronic device 200 and the multi-foldable electronic device 1100 as examples, but may also be applied to bar-type electronic devices, rollable-type electronic devices, wearable-type electronic devices, and / or tablet PCs.

[0138] According to various embodiments, the matching circuit shown in FIG. 13 includes the first matching circuit (S1), the second matching circuit (S2), the third matching circuit (S3), and / or the fourth matching circuit (S4) shown in FIG. 2a, FIG. 3a, FIG. 4, or FIG. 9.

[0140] According to one embodiment, the plurality of passive elements 1320 includes capacitors having various capacitance values ​​and / or inductors having various inductance values.

[0141] According to one embodiment, at least one switch 1310 is coupled to an electrical path 1302 including elements having element values ​​designated under the control of a processor (e.g., processor 120 of FIG. 2a). In some embodiments, the first matching circuit (S1), the second matching circuit (S2), the third matching circuit (S3), or the fourth matching circuit (S4) disconnects the electrical path 1302 through the switch 1310.

[0142] According to one embodiment, the at least one switch 1310 includes a micro-electromechanical systems (MEMS) switch. The MEMS switch performs mechanical switching using an internal metal plate and has a complete turn on / off characteristic, so it does not substantially affect the change in the radiation characteristics of the antenna. In some embodiments, the at least one switch 1310 includes a single pole single throw (SPST), a single pole double throw (SPDT), or a switch with three or more throws.
