Description

Electronic device including an antenna

[0001] The embodiments of the present disclosure relate to an electronic device comprising an antenna.

[0002] Electronic devices are being developed to become increasingly slimmer, increase rigidity, enhance design aspects, and differentiate their functional elements. Electronic devices are moving away from uniform rectangular shapes and are gradually transforming into various shapes. Electronic devices can have a deformable structure that allows for convenient portability and the use of large-screen displays. Electronic devices may include rollable electronic devices (e.g., sliderable electronic devices) capable of varying the display area of ​​a flexible display (e.g., rollable display) through the support of housings that operate in a sliding manner relative to each other. Rollable electronic devices may include at least one antenna among their components that must be provided for communication. Such antennas need to be positioned within the internal space of the electronic device through an efficient design with respect to surrounding structures.

[0003] The information described above may be provided as related art for the purpose of aiding understanding of the present disclosure. No claim or determination is made as to whether any of the foregoing may be applied as prior art related to the present disclosure.

[0004] The electronic device may include a rollable electronic device (e.g., a slideable electronic device) capable of inducing the expansion and / or reduction of the display area of ​​a flexible display (e.g., a rollable display, an expandable display, or a stretchable display) depending on the operating state. The rollable electronic device may include a first housing and a second housing movably coupled to each other. For example, the first housing and the second housing may operate slidably to each other and may support at least a portion of the flexible display, and the flexible display may be induced to have a first display area in a slide-in state and a second display area larger than the first display area in a slide-out state.

[0005] A rollable electronic device may include a support member (e.g., a support bar assembly, a multi-bar assembly, or a bendable member) that moves together with a second housing that slides a certain distance from a first housing and is positioned to support the back surface of a flexible display. This support member may include a plurality of support bars that support the back surface of the flexible display and are spaced apart from each other at a specific interval, and may be accommodated together with the flexible display at least partially in the internal space of the first housing in a retracted state.

[0006] The rollable electronic device may include at least one antenna (e.g., an antenna structure, an antenna member, or an antenna module). The at least one antenna may include a legacy antenna operating in a frequency band of about 600 MHz to 6000 MHz, a 5G antenna operating in a frequency band of about 3 GHz to 300 GHz, or an antenna for measuring the location of an external electronic device located in close proximity. These antennas may utilize at least one conductive part (e.g., a conductive side bezel, a conductive metal bezel, or a conductive side frame) disposed on a part of the side of the electronic device. In this case, the flexible display may be moved while maintaining a certain distance from the conductive part used as an antenna according to the sliding movement of the second housing.

[0007] However, when the flexible display is bent, it may be separated at least partially from the support member due to the repulsive force attempting to unfold, and this lifting phenomenon may cause unstable coupling between the flexible display and the conductive part, thereby degrading the radiation performance of the antenna. Furthermore, as the flexible display moves while in contact with the first housing due to the lifting phenomenon, scratches may occur on the flexible display, and in severe cases, it may lead to damage.

[0008] Various embodiments of the present disclosure can provide an antenna and an electronic device including the same that can help achieve stable radiation performance by maintaining a constant distance between a flexible display and a first housing.

[0009] Various embodiments may provide an antenna and an electronic device including the same that can help reduce damage to a flexible display by reducing the possibility of contact with a housing during operation.

[0010] However, the problems intended to be solved in this disclosure are not limited to those mentioned above, and may be expanded in various ways without departing from the spirit and scope of this disclosure.

[0011] According to various embodiments, the electronic device comprises a first housing including a conductive portion, a second housing slidably coupled to the first housing, a support member that is at least partially accommodated in the internal space of the first housing as the second housing moves, a flexible display disposed to be at least partially supported by the support member, a dielectric structure disposed to support the outer surface of the flexible display between the flexible display and the first housing, and a wireless communication circuit configured to transmit and / or receive a wireless signal in at least one frequency band through the conductive portion, wherein the dielectric structure may be disposed to maintain a constant gap between the flexible display and the first housing.

[0012] An electronic device according to exemplary embodiments of the present disclosure includes a dielectric structure that is positioned between a flexible display and a first housing to maintain a constant gap between the flexible display and the first housing, thereby helping to improve the radiation performance of an antenna and reduce the possibility of damage to the flexible display during movement through stable coupling with the flexible display.

[0095] According to various embodiments, the support plate (450) may provide rigidity and flexibility to the flexible display (230). For example, the support plate (450) may be formed from a non-metallic thin-plate material, such as fiber reinforced plastics (FRP) (e.g., carbon fiber reinforced plastics (CFRP) or glass fiber reinforced plastics (GFRP)), which has rigid characteristics for supporting the display panel (430).

[0101] In describing the electronic device (200) of FIGS. 5a to 6, the same reference numerals have been assigned to components that are substantially identical to those of the electronic device (200) of FIG. 4a, and a detailed description thereof may be omitted.

[0102] Referring to FIGS. 5a through 6, the electronic device (200) may include a first housing (210) having a first space (2101), a second housing (220) having a second space (2201), a support member (240) connected to the second housing (220) and received at least partially into the first space (2101) in an inverted state, a flexible display (230) positioned to receive support from at least a part of the support member (240) and at least a part of the second housing (220), a rack gear (262) fixed to the first space (2101) and extended into the second space (2201), and a drive motor (260) including a pinion gear (261) positioned in the second space (2201) and geared with the rack gear (262). In one embodiment, the drive motor (260) can automatically move the second housing (220) relative to the first housing (210) in the withdrawal direction (direction ①) or the insertion direction (direction ②) through the gear engagement of the pinion gear (261) and the rack gear (262). In some embodiments, the first housing (210) may be automatically moved from the second housing (220) in the withdrawal direction (direction ②) or the insertion direction (direction ①) by changing the arrangement of the drive motor (260) and the rack gear (262). In one embodiment, the first housing (210) may include a first rear cover (213) (e.g., a cover or cover member) coupled with a first side member (211) and a first extension member (212) extending from the first side member (211). In one embodiment, the second housing (220) may include a second rear cover (223) coupled with a second side member (221) and a second extension member (222) extending from the second side member (221).

[0103] According to various embodiments, a portion of the second housing (220) may be accommodated in the first space (2101) of the first housing (210) in the retracted state of the electronic device (200) (state of FIG. 5a). In one embodiment, at least a portion of the flexible display (230) may be accommodated in the first space (2101) by bending it together with a support member (240) so as not to be seen from the outside. In this case, the flexible display (230) may have a first display area (e.g., a display area corresponding to the first portion (230a) of FIG. 3a) exposed to the outside.

[0104] According to various embodiments, at least a portion of the second housing (220) may be transitioned to an out-of-the-box state in which it is moved at least partially out of the first housing (210) along a first direction (direction ①) by driving a drive motor (260). In one embodiment, the flexible display (230) may be exposed so that at least a portion of the portion inserted into the first space (2101) can be seen from the outside by moving together with a support member (240) while being supported by a support bracket (225) in the out-of-the-box state of the electronic device (200) (state of FIG. 5b). In this case, the flexible display (230) may have a second display area (e.g., a display area including the first portion (230a) and the second portion (230b) of FIG. 3a) that is extended beyond the first display area exposed to the outside. In some embodiments, the rack gear (262) may be placed in the second housing (220), and the drive motor (260) including the pinion gear (261) may be placed in the first housing (210).

[0105] According to various embodiments, the electronic device (200) may include a conductive portion (310) disposed through a portion of the first side member (211) of the first housing (210). In one embodiment, the conductive portion (310) forms at least a portion of the side of the electronic device (200) (e.g., the first side (2111) of FIG. 4a) and may be disposed so as to be visible from the outside of the electronic device (200). In one embodiment, the conductive portion (310) may operate as an antenna (A) by being electrically connected to a wireless communication circuit (e.g., the wireless communication module (192) of FIG. 1) disposed on the second substrate (252) and / or the first substrate (e.g., the first substrate (251) of FIG. 4a). In one embodiment, the antenna (A) is positioned in close proximity to the flexible display (230), thereby allowing coupling to occur with layers of conductive material (e.g., layers (240, 450, 440) of FIG. 4b) included in the flexible display (230). For example, the antenna (A) may be affected in its radiation performance when positioned in a first region (210a) of the first housing (210) corresponding to a bending section where the flexible display (230) is bent to be introduced into the first space (2101), and in a second region (210b) of the first housing (210) corresponding to a flat section that maintains a flat surface after the flexible display (230) is introduced into the first space (2101) in an inserted state. For example, the first region (210a) may include a region where the conductive portion (310) is positioned. In one embodiment, the second region (210b) It may include a section corresponding to at least a portion of the first extension member (212) of the conductive material extending from the first side member (211). In one embodiment, the conductive portion (310) used as an antenna (A) is positioned in close proximity to the first extension member (212) formed of the conductive material, so that its radiation performance may be affected, and thus, in the retracted state, it may also be affected by the arrangement structure of the flexible display (230) positioned in close proximity to the first extension member (212).For example, if at least a portion of the flexible display (230) is arbitrarily separated from the support member (240) and a lifting phenomenon occurs toward the first housing (210) in the first region (210a) and / or the second region (210b), the coupling between the conductive portion (310) and the flexible display (230) and / or the flexible display (230) and the first extension member (212) becomes unstable, and the radiation performance may be degraded as a result.

[0106] According to various embodiments, the electronic device (200) may include a dielectric structure (320) disposed between the flexible display (230) and the first housing (210) in a first region (210a) and / or a second region (210b) to reduce unstable coupling changes between the flexible display (230) and the flexible display (230) caused by lifting of the flexible display (230) which causes such degradation of radiation performance. In one embodiment, the dielectric structure (320) may include a dielectric tape having a specific thickness and / or a specific permittivity (e.g., relative permittivity) attached to the inner surface of the first housing (210) in the first region (210a) and / or the second region (210b). In one embodiment, the dielectric structure (320) may be disposed in a manner attached to the inner surface of the first housing (210). In one embodiment, the dielectric structure may be positioned in a manner that contacts the outer surface of the flexible display (230). In one embodiment, the dielectric structure (320) may be formed from a material having a dielectric constant that is relatively less affected by the radiation performance of the antenna. For example, the dielectric structure (320) may be formed from a material having a dielectric constant (e.g., relative dielectric constant) in the range of about 1 < ε ≤ 3.3. In one embodiment, since the dielectric structure (320) contacts the outer surface of the flexible display (230), it may include a hard coating layer or a Teflon coating layer for reducing frictional force placed on the surface that contacts the outer surface of the flexible display (230). In some embodiments, the dielectric structure (320) may be replaced with a Teflon tape having a specific dielectric constant. In some embodiments, the dielectric structure (320) may be formed from a felt material or a sponge material and may act as a sweeper by contacting the outer surface of the flexible display.

[0107] According to various embodiments, the conductive portion (310) may be electrically connected to a second substrate (252) (e.g., a substrate). In one embodiment, the second substrate (252) may be placed in the space between the first extension member (212) and the first rear cover (213). In one embodiment, the electronic device (200) may include a through hole (212b) formed in the first extension member (212) and / or the first side member (211) to connect the space between the first extension member (212) and the first rear cover (213) with the first space (2101). In one embodiment, the second substrate (252) may be electrically connected to the conductive portion (310) in the first space (2101) through an electrical connection member (e.g., a flexible printed circuit board, FPCB) positioned to pass through the through hole (212b). Accordingly, the conductive portion (310) can be configured to transmit and / or receive a wireless signal in at least one specific frequency band (e.g., a frequency band in the range of 600 MHz to 6000 MHz) by being electrically connected to a wireless communication circuit (e.g., a wireless communication module (192) of FIG. 1) disposed on the second substrate (252) and / or the first substrate (e.g., the first substrate (251) of FIG. 4a) through an electrical connection member.

[0108] An electronic device (200) according to exemplary embodiments of the present disclosure can help reduce the degradation of radiation performance of an antenna (A) through a stable coupling structure by maintaining a constant distance from the flexible display (230) through a dielectric structure (320) disposed between the flexible display (230) and the first housing (210).

[0109] FIGS. 7a and 7b are graphs comparing the radiation performance of an antenna in a state where the flexible display and the first housing maintain a uniform gap through a dielectric structure and an lifted state of the flexible display according to various embodiments of the present disclosure.

[0110] Referring to FIG. 7a, when a dielectric structure (320) is placed between the first housing (210) and the flexible display (230) (e.g., graph 701), the separation distance between the conductive part (310) and the flexible display (230) and / or the separation distance between the flexible display (230) and the first extension member (212) is maintained constant even when the flexible display (230) is lifted from the support member (240), thereby allowing the antenna (A) to stably exhibit radiation performance in a specific frequency band (e.g., a frequency band of about 750 MHz). On the other hand, when a dielectric structure (320) is not placed between the first housing (210) and the flexible display (230), and the flexible display (230) is lifted from the support member (240), the separation distance between the conductive part (310) and the flexible display (230) and / or the flexible If the distance between the display (230) and the first extension member (212) changes unevenly (e.g., graph 702), it can be observed that the antenna (A) is low-shifted to an unwanted frequency band (e.g., a frequency band of about 695 MHz). This may mean that if the distance between the conductive part (310) and / or the first extension member (212) and the flexible display (230) is kept constant through the dielectric structure (320), the degradation of the antenna's (A) radiation performance (unintended frequency band shift) can be significantly reduced.

[0111] Referring to FIG. 7b, when a dielectric structure (320) is placed between the first housing (210) and the flexible display (230) (e.g., graph 703), the separation distance between the conductive part (310) and the flexible display (230) and / or the separation distance between the flexible display (230) and the first extension member (212) is maintained constant even when the flexible display (230) is lifted from the support member (240), thereby the antenna (A) exhibits a stable gain in the range of approximately -9dB to -10dB in a specific frequency band (e.g., a frequency band in the range of approximately 730MHz to 750MHz), whereas when a dielectric structure (320) is not placed between the first housing (210) and the flexible display (230), and the flexible display (230) is lifted from the support member (240), the conductive part (310) and the flexible If the distance between the displays (230) and / or the distance between the flexible display (230) and the first extension member (212) changes unevenly (e.g., graph 704), it can be observed that the gain of the antenna (A) is significantly reduced in the range of about -12dB to -14dB in the same frequency band. This may mean that if the distance between the conductive part (310) and / or the first extension member (212) and the flexible display (230) is kept constant through the dielectric structure (320), the degradation of the radiation performance of the antenna (A) (e.g., gain reduction) can be significantly reduced.

[0112] According to an exemplary embodiment of the present disclosure, through a dielectric structure (320) disposed between the first housing (210) and the flexible display (230), the degradation of the radiation performance of the antenna (A) can be reduced, and the antenna (A) may also be designed so that the operating frequency band is intentionally shifted through a change in the dielectric constant and / or shape (e.g., change in aperture ratio) of the dielectric structure (320).

[0113] FIG. 8a is a graph comparing the radiation performance of an antenna according to a change in the permittivity of a dielectric structure placed in a first region according to various embodiments of the present disclosure. FIG. 8b is a graph comparing the radiation performance of an antenna according to a change in the aperture ratio of a dielectric structure placed in a first region according to various embodiments of the present disclosure.

[0114] FIGS. 8a and 8b are graphs illustrating a change in the frequency band of an antenna (A) through a change in the dielectric constant and / or shape of a dielectric structure (320) in a first region (210a) of a first housing (210). In this case, the second region (210b) is conditioned such that the distance between the first housing (210) (e.g., the first extension member (212)) and the flexible display (230) is maintained constant through the dielectric structure (320).

[0115] Referring to FIG. 8a, it can be seen that in the first region (e.g., coupling area 1), as the dielectric constant of the dielectric structure (320) placed between the first housing (210) and the flexible display (230) increases, the operating frequency band of the antenna (A) is low shifted.

[0116] Referring to FIG. 8b, in the first region, it can be seen that as the aperture ratio of the dielectric structure (320) having the same permittivity increases, the operating frequency band of the antenna (A) is high-shifted. For example, the aperture ratio can be adjusted through at least one through hole, slit, or recess formed in the dielectric structure (320) as the ratio of air (e.g., cavity) to the total area of ​​the dielectric structure (320).

[0117] According to an exemplary embodiment of the present disclosure, by changing the dielectric constant and / or shape (e.g., aperture ratio) of a dielectric structure (320) disposed between a first housing (210) (e.g., conductive portion (310)) and a flexible display (230), the antenna (A) can be easily adjusted to an operating frequency band without a matching circuit.

[0118] FIG. 9a is a graph comparing the radiation performance of an antenna according to a change in the permittivity of a dielectric structure placed in a second region according to various embodiments of the present disclosure. FIG. 9b is a graph comparing the radiation performance of an antenna according to a change in the aperture ratio of a dielectric structure placed in a second region according to various embodiments of the present disclosure.

[0119] FIGS. 9a and 9b are graphs illustrating a change in the frequency band of an antenna (A) through a change in the dielectric constant and / or shape of a dielectric structure (320) in a second region (210b) of a first housing (210). In this case, the first region (210a) is conditioned such that the distance between the first housing (210) (e.g., the conductive part (310)) and the flexible display (230) is maintained constant through the dielectric structure (320).

[0120] Referring to FIG. 9a, it can be seen that in the second area (e.g., coupling area 2), as the dielectric constant of the dielectric structure (320) placed between the first housing (210) and the flexible display (230) increases, the operating frequency band of the antenna (A) is low shifted.

[0121] Referring to FIG. 9b, in the second region, it can be seen that as the aperture ratio of the dielectric structure (320) having the same permittivity increases, the operating frequency band of the antenna (A) is high-shifted. For example, the aperture ratio can be adjusted through at least one through hole, slit, or recess formed in the dielectric structure (320) as the ratio of air (e.g., cavity) to the total area of ​​the dielectric structure (320).

[0122] According to an exemplary embodiment of the present disclosure, by changing the dielectric constant and / or shape (e.g., aperture ratio) of a dielectric structure (320) disposed between a first housing (210) (e.g., first extension member (212)) and a flexible display (230), the antenna (A) can be easily adjusted to an operating frequency band without a matching circuit.

[0125] Referring to FIG. 10a, the electronic device (200) may include a plurality of rollers (330) of a dielectric material as a dielectric structure disposed between a first housing (210) and a flexible display (230) and between a conductive portion (310) of the first housing (210) and the flexible display (230) and / or between a first extension member (212) and the flexible display (230). In one embodiment, the plurality of rollers (330) may be disposed at specific intervals from a first region (210a) to a second region (210b) in a first space (2101) of the first housing (210). In one embodiment, the plurality of rollers (330) may be disposed to contact the outer surface of the flexible display (230). In one embodiment, a plurality of rollers (330) are arranged to rotate independently in the first space (2101) of the first housing (210) so that they rotate in conjunction with the movement of the flexible display (230), thereby helping to reduce friction. In one embodiment, the plurality of rollers (330) may be arranged so as not to come into contact with the inner surface of the first housing (210) (e.g., the conductive part (310) and / or the first extension member (212)). In one embodiment, the plurality of rollers (330) are rotatably fixed in the first space (2101) of the first housing (210) so that the distance between the flexible display (230) and the first housing (210) can be maintained constant even without support from the inner surface of the first housing (210).

[0126] As described, a plurality of rollers (330) are arranged in eight places between the conductive part (310) and the flexible display (230) in the first area (210a), and in six places between the first extension member (212) and the flexible display (230) in the second area (210b), but are not limited thereto. For example, the plurality of rollers (330) may be changed to an appropriate number depending on the size of the bending radius of the flexible display (230) and / or the degree of insertion of the flexible display (230).

[0127] Referring to FIG. 10b, a plurality of rollers (330) may be arranged to cross the width direction (e.g., ±x axis direction) in the first space (2101) of the first housing (210).

In one embodiment, the roller member (331) may be formed of a material that does not provide elasticity of its own. In some embodiments, the roller member (331) may be formed of a low-elasticity material.

[0129] Referring to FIG. 10d, each of the plurality of rollers (330) may include a plurality of roller members (331) spaced apart at specific intervals on a single shaft (332). The arrangement structure of the plurality of roller members (331) spaced apart on a single shaft (332) can help reduce friction with the flexible display (230) and help control the coupling amount between the flexible display (230) and the conductive part (310) for setting the frequency of the antenna (A).

[0131] In describing the electronic device (200) of FIG. 11a, the same reference numerals have been assigned to components that are substantially identical to those of the electronic device (200) of FIG. 6, and a detailed description thereof may be omitted.

[0132] Referring to FIG. 11a and FIG. 11b, the electronic device (200) may include a belt member (340) of dielectric material as a dielectric structure disposed between a first housing (210) and a flexible display (230), and between a conductive portion (310) of the first housing (210) and the flexible display (230) and / or between a first extension member (212) and the flexible display (230). In one embodiment, the belt member (340) may include a first belt (342) disposed between the conductive portion (310) and the flexible display (230) in a first region (210a) of the first housing (210), and a second belt (343) disposed between the first extension member (212) and the flexible display (230) in a second region (210b).

[0137] According to various embodiments, the first belt (352) may be wound around a plurality of rollers (3511, 3512, 3513, 3514, 3515) rotatably arranged along the inner curve of the conductive portion (310) in the first region (210a) and arranged to have elastic contact with the outer surface of the flexible display (230).
