Description

Technical Field

[0001] Embodiments of this disclosure relate to antennas and electronic devices including antennas. Background Technology

[0002] As the functional differences between manufacturers become increasingly narrow, electronic devices are becoming slimmer to meet consumer purchasing expectations, and they are being developed to differentiate their functional elements while increasing rigidity and strengthening the design. As part of this trend, electronic devices are being developed to achieve superior radiation performance through structural changes in at least one antenna that must be provided for communication between their components. Summary of the Invention

[0003] Technical issues

[0004] Electronic devices may include foldable electronic devices comprising a first housing and a second housing foldably connected to the first housing via a hinge device. The electronic device may include a first display (e.g., a flexible display) used in an unfolded state and disposed from the first housing to be supported by at least a portion of the second housing via the hinge device. The electronic device may include a second display (e.g., a sub-display) used in a folded state and disposed in the first or second housing in an unfolded state, facing the opposite direction to the first display. Some electronic devices (e.g., strip-shaped electronic devices) may include a first display disposed on a front surface and a second display disposed on a rear surface within a single housing.

[0005] The electronic device may include at least one antenna disposed within the interior space of at least one housing, or may include at least one antenna utilizing at least a portion of a conductive side surface (e.g., an antenna included within a metal frame). The size and number of such antennas may be determined by the frequency, bandwidth, and / or type of service through which the electronic device will communicate.

[0006] However, while electronic devices require antennas with different frequency bands and wide bandwidths, they can include large-screen displays. Large-screen displays that include electronic devices can complicate antenna placement.

[0007] Furthermore, if the antenna is positioned between the first and second displays and / or near a metal frame that serves as another antenna, the radiation performance may be reduced due to the first and / or second displays (e.g., null values ​​appear). Additionally, if the antenna is positioned between and / or near the curved areas of a flexible display, the electronic device may also have reduced radiation performance.

[0008] Various embodiments of this disclosure may provide an antenna and an electronic device including the antenna, wherein enhanced radiation performance is achieved by using some components of the display as radiators.

[0009] Various embodiments may provide an antenna and an electronic device including the antenna that improves radiation performance without affecting or degrading the performance of other nearby antennas.

[0010] Various embodiments may provide an antenna and electronic devices including the antenna, which are configured to facilitate frequency shifting and / or bandwidth expansion.

One of these communication modules can communicate with an external electronic device via a first network 198 (e.g., a short-range communication network such as Bluetooth, Wi-Fi Direct, or Infrared Data Association (IrDA)) or a second network 199 (e.g., a long-range communication network such as a traditional cellular network, 5G network, next-generation communication network, the Internet, or a computer network (e.g., a LAN or a wide area network (WAN))). These various types of communication modules can be implemented as a single component (e.g., a single chip) or as multiple components separate from each other (e.g., multiple chips). The wireless communication module 192 can identify and verify the electronic device 101 in the communication network (such as the first network 198 or the second network 199) using user information (e.g., the International Mobile Subscriber Identity (IMSI)) stored in the user identification module 196.

In one embodiment, at least a portion of the cover member 485 may be attached to the plate by a third adhesive member T3. In one embodiment, the third adhesive member T3 may be formed of substantially the same material as the aforementioned first adhesive member T1 and / or second adhesive member T2.

[0109] According to various embodiments, the electronic device 300 may include an antenna that operates via at least a portion of a conductive sheet 450 attached beneath the display panel 430. In one embodiment, the electronic device 300 may include a wireless communication circuit electrically connected to the board 361 at a first point L1 of the conductive sheet 450 (e.g., Figure 6a Wireless communication circuit 192 (e.g., Figure 1 The first power supply unit F1 of the wireless communication module 192. In one embodiment, the electronic device 300 may include a support bracket 318 disposed in the internal space 3101 between the board 361 and the display 400 (e.g., Figure 4The first support member 3131). In one embodiment, the support bracket 318 may serve as an antenna carrier to accommodate at least one antenna pattern (e.g., laser direct structured pattern (LDS)) in the internal space 3101 of the first housing 310, or as a support structure to support plates 361 and 361-1 or other electrical structures. In one embodiment, the conductive sheet 450 may be electrically connected to the wireless communication circuit 192 of the plate 361 via a conductive extension 3181a configured to at least partially penetrate the support bracket 318 (e.g., antenna carrier or support member), a conductive pad 3181 electrically connected to the conductive extension, and a conductive contact 3182 (e.g., C-clamp) electrically connected to the conductive extension 318a. In one embodiment, the conductive extension 3181a may include a conductive path penetrating at least a portion of the support bracket 318, and the conductive pad 3181 may be electrically connected to the conductive extension 3181a and formed to have a specified thickness on the outer surface of the support bracket 318. In one embodiment, the conductive pad 3181 may be omitted if a portion of the conductive extension 3181a is exposed on the outer surface of the support bracket 318. In one embodiment, the electronic device 300 may include a ground portion G1 electrically connected to the ground G of the board 361 at a second point L2 spaced at a predetermined interval from the first point L1. In one embodiment, the ground portion G1 may be electrically connected to the bend 432 and may be formed by a connector 433 for transmitting control signals for the display 400. In this case, the connector 433 may electrically connect the ground G of the board 361 to the conductive sheet 450 at the second point L2 via a conductive connection member 4331. In one embodiment, the conductive connection member 4331 may include at least one of a metallic material, a conductive strip, a conductive foam, or a conductive contact (e.g., a C-clamp). In some embodiments, the ground portion G1 may be formed in substantially the same manner as the power supply unit F1 by the support bracket 318 including the conductive extension 3181a and the conductive pad 3181, and the conductive contact 3182. In some embodiments, the construction of the ground portion G1 may be omitted. In one embodiment, the antenna can operate in a specified frequency band (e.g., about 400 MHz to about 6000 MHz) by causing a change in the flow of current applied to the conductive sheet 450 by means of the placement of the grounding part G1.

[0110] Figure 6a This is a partial structural diagram of an electronic device, illustrating the electrical connection structure between a wireless communication circuit and a power supply unit according to various embodiments of the present disclosure.

[0111] Reference Figure 6aThe electronic device 300 may include a power supply unit F1, which is electrically connected to the wireless communication circuit 192 of the conductive sheet 450 and the plate 361 via conductive pads 3181, conductive extensions 3181a, and conductive contacts 3182 (e.g., C-clamps) electrically connecting the conductive extensions 3181a and the plate 361, respectively, on a support bracket 318 (which is located in the internal space 3101 of the first housing 3100). In one embodiment, the power supply unit F1 may be electrically connected to the wireless communication circuit 192 located at a distance from the power supply unit F1 via an electrical path 3108 (e.g., a wiring path) located on the plate 361. In one embodiment, the wireless communication circuit 192 may be located on an auxiliary plate 361-1, which is electrically connected to the plate 361 via an interposer. In one embodiment, the electronic device 300 may help offset the operating frequency band of the antenna or extend the bandwidth of the operating frequency by including a matching circuit M (e.g., a tunable element (capacitor and / or inductor) or a tunable IC) deployed along the electrical path 3108.

[0112] Figure 6b and Figure 6c This is a partial cross-sectional view of an electronic device, illustrating the electrical connection structure of conductive sheets and plates according to various embodiments of the present disclosure.

[0113] Reference Figure 6b The conductive sheet 450 of the display 400 can form a first power supply unit F1 by means of a conductive pad 3181, a conductive extension 3181a disposed on the support bracket 318, and a conductive contact 3182 connecting the conductive extension 3181a and the board 361 to a wireless communication circuit 192 of the board 361. In this case, the conductive pad 3181 can be in direct contact with the conductive sheet 450 (e.g., a direct power supply method).

[0114] Reference Figure 6c ,exist Figure 6b In the construction, the conductive sheet 450 of the display 400 can be electromagnetically connected to the conductive pad 3181 spaced apart from it by means of capacitive connection (e.g., indirect power supply method).

[0115] Figure 7a This is a diagram illustrating the feed points of conductive sheets in an electronic device according to various embodiments of the present disclosure.

[0116] Reference Figure 7a The electronic device 300 may include a hinge structure (e.g., Figure 2b The hinge structure 340 (e.g., hinge device) foldably connects the first housing 310 and the second housing (e.g., Figure 2aThe second housing 320). In one embodiment, the electronic device 300 may include a plate 361 (e.g., a circuit board) disposed in the first housing 310. In one embodiment, the electronic device 300 may include a first display (e.g., Figure 3a The first display (330) and the second display (e.g., a second display) are configured to be supported by a first housing 310 and a second housing 320 and to point in a first direction (e.g., the z-axis direction). The second display (400) is configured to be located within the internal space 3101 of the first housing 310 and to be accessible via a first rear cover (e.g., ...). Figure 4 The first rear cover 314 is visible from the outside and points in a second direction opposite to the first direction (e.g., the -z axis direction). In one embodiment, the electronic device 300 may include a wireless communication circuit (e.g., Figure 6a Wireless communication circuit 192 (e.g., Figure 1 The wireless communication module 192) has a power supply unit F1, which is disposed on the plate 361 at point L1 of the rectangular conductive sheet 450. For example, the power supply unit F1 may be disposed near a corner C on one side of the conductive sheet 450 of the display 400 or in an area extending from the corner C. In one embodiment, the area A where the power supply unit F1 is located may be defined as a square-shaped area (e.g., a square area) having a horizontal length of approximately λ / 8 (in the -x-axis direction) and a vertical length of approximately λ / 8 (in the -y-axis direction). The square-shaped area may be located in the corner C of the conductive sheet 450 such that the first horizontal side of the area A substantially coincides with the first horizontal edge of the conductive sheet 450 (i.e., sharing an edge), and the first vertical side of the area A (which is adjacent to the first horizontal side of the area A) coincides with the first vertical side of the conductive sheet 450 (which is adjacent to the first horizontal side of the conductive sheet 450) (i.e., sharing an edge). Alternatively, if the conductive sheet is rectangular, then region A can be a square-shaped region extending λ / 8 from the first corner of the conductive sheet in a first direction toward a second corner adjacent to the first corner, and in a second direction toward a third corner adjacent to the first corner. This arrangement of region A in the feed unit F1 can induce the antenna to utilize more of its operating frequency band.

[0117] Figure 7b It is a comparison of various embodiments according to this disclosure. Figure 7a A graph showing the radiation performance of an antenna at the feed point of a conductive sheet.

[0118] Reference Figure 7b It can be seen that, although when the power supply unit F1 is set Figure 7aWhen the feed element F1 is located in region A of the conductive sheet 450, a dual resonance is formed in the first frequency band 701 (e.g., about 3.3 GHz to about 3.7 GHz) and the second frequency band 702 (e.g., about 4.2 GHz to about 4.6 GHz) under direct feeding (curve 711) or indirect feeding (curve 712). However, when the feed element F1 is located in regions B (curve 713), C (curve 714), and D (curve 715), a single resonance of the antenna is formed only in the second frequency band, where regions B, C, and D are all outside region A. This means that if the feed element F1 is located in a square region with a length of about λ / 8 on one side about a corner C of the conductive sheet 450, the antenna can have better radiation performance compared to the case where the feed element F1 is located outside such a region (i.e., approximately not in the corner of the conductive sheet 450). In other words, if the feed element F1 is connected to the conductive sheet 450 within approximately λ / 8 of the radius of the corner (i.e., position L1 is within approximately λ / 8 of the radius of the corner of the conductive sheet 450), the antenna can have better radiation performance compared to the case where the feed element F1 is connected outside such a region. Although region A has been described as having a size of approximately λ / 8, it is not limited to these dimensions; for example, region A can have a size smaller than λ / 8. Furthermore, although region A is primarily described as having a square shape, it can also take on other shapes with a size of approximately λ / 8 relative to the corner of the conductive sheet and resulting in antenna characteristics similar to those described above. Furthermore, although in Figure 7a A specific corner C is shown, but the region A can be defined relative to any corner of the conductive sheet 450.

[0119] Figure 8 It is a graph comparing the bandwidth characteristics of antennas according to various embodiments of the present disclosure.

[0120] Reference Figure 8 As can be seen, when only the feed unit F1 (in position L1) is electrically connected to the wireless communication circuit 192 of board 361, the antenna using conductive sheet 450 can operate, for example, in the first frequency band 703 (e.g., about 3.5 GHz) and the second frequency band 704 (e.g., about 4.4 GHz) (relative to the -6 dB operating range) (curve 721). However, when the antenna includes a ground portion G1 spaced apart from the feed unit F1 and electrically connected to the ground G of board 361, the antenna can operate, for example, with a relatively wide bandwidth (region 705) (e.g., about 3.6 GHz to about 4.7 GHz) (relative to the -6 dB operating range) (curve 722). In this case, the bandwidth of the antenna can be appropriately adjusted by the matching circuit M provided in the electrical path 3108 connecting the feed unit F1 and the wireless communication circuit 192.

[0121] Figure 9a This is a diagram used to illustrate the location of the ground portion of a conductive sheet in an electronic device according to various embodiments of the present disclosure.

[0122] exist Figure 9a In the description of the electronic device 300, the same reference numerals are assigned to... Figure 5b The components of the electronic device 300 are substantially the same, and their detailed descriptions may be omitted.

[0123] Reference Figure 9a The electronic device 300 may include a wireless communication circuit electrically connected to the board 361 at a first point L1 of the conductive sheet 450 (e.g., Figure 6a The wireless communication circuit 192) includes a power supply unit F1. In one embodiment, the electronic device 300 may include a first ground portion G1, which is electrically connected to the ground G of the board 361 at a second point L2 of the conductive sheet 450, which is spaced apart from the first point L1 by a predetermined interval. In some embodiments, the first ground portion G1 may be replaced by a second ground portion G2 disposed at a third point L3 of the conductive sheet 450, which is closer to the first point L1 than the second point L2. In some embodiments, the first ground portion G1 may be replaced by a third ground portion G3 disposed at a fourth point L4 of the conductive sheet 450, which is farther from the first point L1 than the second point L2. For example, the antenna using the conductive sheet 450 of the display 400 may have variable radiation characteristics (e.g., shift in operating frequency band) depending on the separation distance of the ground portions G1, G2, and G3 from the power supply unit F1 (i.e., the separation of point L1 from L2, L3, and L4). In one embodiment, the grounding portion G1 spaced apart from the power supply unit F1 can vary depending on the position of the connector 433. For example, the connector 433 can be changed to the position of the second grounding portion G2 or the third grounding portion G3 by means of a change in the shape of the connector 433 located on the first grounding portion G1. The second grounding portion G2 or the third grounding portion G3 allows the conductive piece 450 to be electrically connected to the ground G of the board 361 at the third point L3 or the fourth point L4. In some embodiments, the first grounding portion G1, the second grounding portion G2, or the third grounding portion G3 can be changed without using the connector 433 by changing the separately provided conductive connection member (e.g., Figure 11 The conductive connecting member 319 is positioned such that the conductive sheet can be electrically connected to the ground G of the board 361 at the corresponding position. In some embodiments, the first ground part G1, the second ground part G2 and / or the third ground part G3 can all be disposed on the conductive sheet 450, and one of these ground parts can be selectively connected to the ground G of the board 361 by a switching circuit in order to control the bandwidth of the antenna.

[0124] Figure 9b This illustrates various embodiments according to the present disclosure. Figure 9aA graph showing the frequency characteristics of an antenna at the grounding position of a conductive sheet.

[0125] Reference Figure 9b When the grounding part is not applied, that is, when the grounding part is not connected to the conductive piece 450 (curve 731), the antenna using the conductive piece 450 of the display 400 can operate in the first band (about 3.5 GHz) of the N77 band (e.g., 3.3 GHz to 4.2 GHz). In one embodiment, it can be seen that when the first grounding part G1 is located at a second point L2 spaced apart from the feed unit F1 (curve 732), the antenna operates in the second frequency band of the N77 band (e.g., the approximately 3.9 GHz band); when the first grounding part G1 is replaced by a second grounding part G2 located at a third point L3, the third point L3 is closer to the feed unit F1 than the second point L2 (curve 733), and the antenna operates in the third frequency band of the N77 band, which is higher than the second frequency band (e.g., the approximately 4.1 GHz band); when the first grounding part G1 is replaced by a third grounding part G3 located at a fourth point L4, the fourth point L4 is farther from the feed unit F1 than the second point L2 (curve 734), and the antenna operates in the fourth frequency band of the N77 band, which is lower than the second frequency band (e.g., the approximately 3.55 GHz band). For example, it can be seen that the operating frequency of the antenna is shifted lower as the distance of the grounding part G1 from the feed element F1 (i.e., L1) increases, and shifted higher as it gets closer to the feed element F1. This may mean that the antenna resonance can be controlled within a desired frequency band (e.g., the N77 band) depending on the distance of the grounding parts (e.g., G1, G2, G3) from the feed element F1. Although in Figure 9a The grounding portions have been shown to be located in specific positions, but they are not limited to these positions and can be located anywhere on the conductive sheet 450 depending on the desired frequency characteristics of the antenna.

[0126] Figure 10a and Figure 10b This is a graph comparing the current distribution of the antenna with and without a grounding portion according to various embodiments of the present disclosure.

[0127] Reference Figure 10a When no grounding is applied, the antenna using the conductive sheet 450 of the display 400 can resonate through a first current distribution region 706 of a square or rectangular shape in a designated area starting from a corner of the conductive sheet 450.

[0128] Reference Figure 10bWhen a ground portion G1 is included, located at a second point L2 spaced apart from the feed unit F1, the antenna using the conductive sheet 450 of the display 400 can resonate through the ground portion G1 via a second current distribution region 707 smaller than the first current distribution region 706. This may mean that the resonance of the antenna can be controlled according to the ground portion G1 spaced apart from the feed unit F1.

[0131] Reference Figure 11 The grounding portion G1 may include a separate conductive connection member 319 instead of the connector 433 of the bend 432 extending from the display panel 430. For example, the conductive connection member 319 may be disposed between the display 400 and the plate 361 to connect the ground G of the conductive sheet 450 and the plate 361. In one embodiment, the conductive connection member 319 may include at least one of a metallic material, a conductive strip, a conductive foam, or a conductive contact (e.g., a C-clamp).

Figure 12b It is according to various embodiments of this disclosure along Figure 12a A partial cross-sectional view of the electronic device taken from line 12b-12b.

[0133] exist Figure 12a In the description of the electronic device 300, the same reference numerals are assigned to... Figure 5b The components of the electronic device 300 are substantially the same, and their detailed descriptions may be omitted.

[0134] Reference Figure 12a and Figure 12b The electronic device 300 may include a hinge structure (e.g., Figure 2b The hinge structure 340 (e.g., hinge device) foldably connects the first housing 310 and the second housing (e.g., Figure 2aThe second housing 320). In one embodiment, the electronic device 300 may include a display 400 disposed in the interior space 3101 of the first housing 310 such that it can be seen from the outside through the first rear cover 314. In one embodiment, the electronic device 300 may include a first antenna A operated by a feeding unit F1, which is electrically connected at a first point L1 of the conductive sheet 450 to the wireless communication circuitry of the board 361 (e.g., Figure 6a Wireless communication circuit 192).

[0135] According to various embodiments, the electronic device 300 may include a first side member 313 forming a side surface of a first housing 310 and formed of a conductive material 313a. In one embodiment, the first side member 313 may include a first conductive member 210 segmented by a pair of spaced-apart segmented portions 211 and 212 and a second conductive member 220 segmented by another pair of segmented portions 221 and 222, such that the segments of the conductive portions are electrically isolated from each other. In one embodiment, the first conductive member 210 may be electrically connected to a wireless communication circuit of the board 361 (e.g., via conductive contact 3182) through a conductive contact 3182. Figure 1 The wireless communication module 192 operates as the second antenna A1. In one embodiment, the second conductive member 220 may also operate as the third antenna A2 by means of a connection structure substantially the same as that of the second antenna A1. For example, the second antenna A1 and / or the third antenna A2 may operate in at least one frequency band in the range of about 400 MHz to about 6000 MHz. In one embodiment, the conductive material 313a of the first conductive member 210 and / or the second conductive member 220 may be configured to have a predetermined separation distance d1 from the conductive sheet 450 of the display 400. For example, the separation distance d1 may be about 2 mm or greater.

[0136] Figure 13 This is a graph comparing the performance of the frame antenna with and without the antenna A formed by the conductive sheet 450 according to various embodiments of the present disclosure.

[0137] Reference Figure 13It can be seen that the radiation performance of the second antenna A1 when the first antenna A is absent (curve 741) and the radiation performance of the second antenna A1 when the first antenna A is present (curve 742) are essentially unchanged. Furthermore, it can be seen that the radiation performance of the third antenna A2 when the first antenna A is absent (curve 743) and the radiation performance of the third antenna A2 when the first antenna A is present (curve 744) are essentially unchanged. Moreover, it can be seen that the first antenna A using the conductive sheet 450 of the display 400 operates in a different frequency band than the second antenna A1 and the third antenna A2 (curve 745). This implies that even if the electronic device 300 includes antenna A using the conductive sheet 450 of the display 400, it will not affect the radiation performance of at least one frame antenna A1 and A2 using a portion of the side member 313, and they can operate smoothly.

[0138] Figure 14a This is a partial structural diagram of an electronic device including a connector cable according to various embodiments of the present disclosure. Figure 14b It is according to various embodiments of this disclosure along Figure 14a A partial cross-sectional view of the electronic device taken from line 14b-14b.

[0139] exist Figure 14a In the description of the electronic device 300, the same reference numerals are assigned to... Figure 9a The electronic device 300 has essentially the same components, and its detailed description can be omitted.

[0140] Reference Figure 14a and Figure 14b The display 400 may include a connector cable 435 that connects the bend 432 and the connector 433 in the design structure of the electronic device 300. Such a connector cable 435 may be configured to overlap with the conductive sheet 450 of the display 400, and the conductive lines and / or ground planes included in the connector cable 435 may cause coupling with the conductive sheet, which may affect the radiation characteristics of the antenna to be determined by the grounding part G1.

[0141] In an illustrative embodiment of this disclosure, connector cable 435 can help determine the radiation characteristics of the antenna formed by conductive sheet 450 using ground portion G1 by including a ground pad 4351 electrically connected to conductive sheet 450. In one embodiment, ground pad 4351 can be electrically connected to ground G of board 361 via connector 433.

[0142] Figure 15a and Figure 15b It is a comparison of various embodiments according to this disclosure in having or not having Figure 14a The diagram shows the current distribution of the antenna in the case of the grounding pad.

[0143] Reference Figure 15a When connector cable 435 is present but ground pad 4351 is absent, unintentional resonance can occur in the antenna of conductive piece 450 in the first current distribution region 708, where the current distribution region 708 from feed unit F1 extends to at least a portion of the area overlapping with connector cable 435, regardless of ground portion G1. However, when ground pad 4351 is applied to connector cable 435, the antenna can resonate through a second current distribution region 709 smaller than the first current distribution region 708. This could mean that even if connector cable 435 is configured to overlap conductive piece 450, the antenna resonance can be smoothly controlled by ground portion G1 spaced apart from feed unit F1 by means of ground pad 4351.

[0144] Figure 16 It is a comparison of various embodiments according to this disclosure in having or not having Figure 14a The curve showing the radiation characteristics of the antenna in the case of a grounding pad.

[0145] Reference Figure 16 As can be seen, compared with when only the power supply unit F1 is applied (curve 751) and when only the ground pad 4351 is applied to the connector cable 435 (curve 752), when the ground pad 4351 is applied to the connector cable 435 and the ground part G1 is also applied (curve 753), the antenna using the conductive sheet 450 of the display 400 operates in a relatively wide bandwidth (e.g., about 3.4 GHz to about 4 GHz).

[0146] Figure 17 It is a comparison according to various embodiments of the present disclosure when ground pad 4351 is present. Figure 14a A graph showing the frequency characteristics of the antenna at the locations of the grounding parts (G1, G2, G3) in the diagram.

[0147] Reference Figure 17As can be seen, when the first grounding part G1 is located at the second point L2, which is spaced apart from the feed unit F1 located at the first point L1 (curve 761), the antenna, utilizing the conductive sheet 450 of the display 400 and the grounding structure in which a portion of the connector cable is grounded through the grounding pad, operates in the first band of the N77 band (e.g., the approximately 3.8 GHz band); when the first grounding part G1 is replaced by the second grounding part G2 located at the third point L3, which is closer to the feed unit F1 than the second point L2 (curve 762), the antenna operates in the second band of the N77 band, which is higher than the first band of the N77 band (e.g., the approximately 3.9 GHz band); when the first grounding part G1 is replaced by the third grounding part G3 located at the fourth point L4, which is farther from the feed unit F1 than the second point L2 (curve 763), the antenna operates in the third band of the N77 band, which is lower than the first band (e.g., the approximately 3.63 GHz band). For example, it can be seen that even if the connector cable 435 is arranged to overlap with the conductive sheet 450, through the grounding structure of the ground pad 4351, the ground portion G1 shifts lower as the distance from the feed unit F1 increases, and shifts higher as it gets closer to the feed unit F1. This means that even if the connector cable 435 is arranged to overlap with the conductive sheet 450, the antenna resonance can be controlled in the desired frequency band (e.g., the N77 band) according to the separation distance of the ground portion G1, which is spaced apart from the feed unit F1 and electrically connected to the ground G of the board 361 through the connector 433, while the grounding position of the ground pad 4351 is maintained. The connector cable overlapping the conductive sheet as described here means that the connector cable is directly adjacent to the conductive sheet, or that the connector cable is separated from the conductive sheet through one or more intermediate layers.

Figure 19 It is a comparison of various embodiments according to this disclosure in having or not having including Figure 18 The graph shows the performance of the frame antenna in the case of an antenna with a grounding pad.

[0149] exist Figure 18 In the description of the electronic device 300, the same reference numerals are given as... Figure 12a The components of the electronic device 300 are substantially the same, and their detailed description can be omitted.

[0150] Reference Figure 18The electronic device 300 may include a first antenna A having a grounded structure, wherein a portion of the connection bend 432 of the connector cable 435 and a portion of the connector 433 are electrically connected to the conductive sheet 450 via a grounding pad 4351. In one embodiment, the electronic device 300 may include a second antenna A1 (e.g., a second frame antenna) and / or a third antenna A2 (e.g., a third frame antenna) formed through at least a portion of the first side member 313 of the first housing 310.

[0151] Reference Figure 19 It can be seen that when there is no Figure 19 The radiation performance of the second antenna A1 when the first antenna A is present (curve 771) and the radiation performance of the second antenna A1 when the first antenna A is present (curve 772) remain unchanged. Furthermore, it can be seen that the radiation performance of the third antenna A2 when the first antenna A is absent (curve 773) and the radiation performance of the third antenna A2 when the first antenna A is present (curve 774) remain unchanged. Additionally, it can be seen that the first antenna A, with its grounding structure of the connector cable 435 using the conductive sheet 450 of the display 400, operates in a different frequency band than the second antenna A1 and the third antenna A2 (curve 775). This could mean that even if the connector cable 435 is configured to overlap with the conductive sheet 450, the grounding structure of the first antenna A1, including the ground pad 4351, will not affect the radiation performance of at least one frame antenna A1 and A2 using a portion of the side member 313, and they can operate smoothly.

[0154] According to various embodiments, the second housing 520 and the third housing 530 can be operated via a second hinge device 562 using a second folding method (e.g., an inward folding method). For example, the second housing 520 and the third housing 530 can be folded such that, in the folded state, the display areas facing each housing 520 and 530 face each other. In one embodiment, the electronic device 500 can operate with the first housing 510, the second housing 520, and the third housing 530 fully extended. In one embodiment, the electronic device 500 can operate with only the first housing 510 and the second housing 520 folded. In one embodiment, the electronic device 500 can operate with all three housings folded. In one embodiment, the display area facing the first housing 510 can be positioned facing outwards from the electronic device 500 in a fully folded state, making it visible to the user. In such a case, the camera module 514 and the sensor module 515 can be configured to detect the external environment via the display area corresponding to the first housing 510. In some embodiments, the camera module 514 and / or the sensor module 515 may be positioned below the flexible display 540 so that they are not visible from the outside.

Figure 5c The conductive pads 3181 and / or conductive contacts 3182) are electrically connected at the first point L1 to a wireless communication circuit disposed on the board 550 (e.g., Figure 1 The wireless communication module 192). For example, even when the first region DA1 of the flexible display 540 overlaps with the second region DA2 and / or the third region DA3 in the folded state, the antenna using the conductive sheet 541 can operate smoothly. In some embodiments, the conductive sheet 541 can help determine the radiation characteristics of the antenna by including a ground portion G1, which is connected to the feed unit F1 at a second point (e.g., L2) via an electrical connection member 551 (e.g., ...).
