Description

Electronic device including an antenna

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

[0002] Electronic devices are becoming increasingly slimmer, more rigid, and more aesthetically pleasing, while simultaneously being developed to differentiate their functional elements. Electronic devices are moving beyond their standard rectangular form factor and are evolving into increasingly diverse shapes. Electronic devices may have a transformable structure that is both portable and capable of utilizing a large-screen display. Electronic devices may have a structure (e.g., a rollable structure or a slideable structure) that allows the display area of ​​a flexible display (e.g., a rollable display) to be varied by supporting housings that slide relative to each other. Such electronic devices may include at least one antenna (e.g., an antenna module or an antenna structure).

[0003] The above information may be provided as background art to aid in understanding the present disclosure. No claim or determination is made as to whether any of the above is applicable as prior art related to the present disclosure.

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

[0005] A rollable electronic device may include an antenna configured to transmit and / or receive a wireless signal in a designated frequency band via at least one conductive portion disposed on at least a portion of a side surface (e.g., a side member) of a first housing and / or a second housing formed of a conductive material. Since the antenna is coupled through a relatively wide overlapping area of ​​the two housings when in a retracted state, excellent radiation performance can be exhibited under stable ground conditions.

[0006] However, in the pulled-out state, the overlapping area of ​​the first housing and the second housing is relatively reduced or separated, which reduces the coupling area and changes to an unstable ground condition, which may generate a parasitic resonance frequency in the operating frequency band, and this parasitic resonance frequency may deteriorate the radiation performance of the antenna.

[0007] To improve this problem, a conductive contact, such as a C-clip, may be placed as an electrical connection member between the side of the first housing and the side of the second housing.

[0008] However, the conductive contact may increase the volume of the electronic device, may cause difficulty in resistance management because the first and second housings are in point contact, may cause drive loss due to increased friction between the two housings, and may cause noise during operation.

[0009] Various embodiments of the present disclosure can provide an electronic device including an antenna that can maintain excellent radiation performance even in an extended state.

[0010] Various embodiments may provide an electronic device including an antenna that may exhibit improved radiation performance by inducing stable coupling between two housings in an extended state.

[0011] Various embodiments may provide an electronic device including an antenna that may help improve radiation performance and slim down the electronic device through minimal layout design.

[0012] Various embodiments may provide an electronic device including an antenna that may exhibit improved radiation performance through the elimination of parasitic resonant frequencies in an operating frequency band.

[0013] However, the problem to be solved in this disclosure is not limited to the problem mentioned above, and may be expanded in various ways without departing from the spirit and scope of this disclosure.

[0014] According to various embodiments, an electronic device includes a first housing formed of a conductive material, a second housing slidably coupled from the first housing and including at least one first conductive portion, the second housing formed of a conductive material, a communication circuit disposed in an internal space of the electronic device and configured to transmit and / or receive a wireless signal in a first frequency band through the at least one first conductive portion, and at least one dielectric disposed between the first housing and the second housing, wherein in a slide-out state, the first housing and the second housing include an overlapping area in which they at least partially overlap, and the at least one dielectric can be disposed in the overlapping area.

[0015] An electronic device according to exemplary embodiments of the present disclosure is arranged in an overlapping area between a first housing and a second housing in an extended state, and includes a sheet-shaped dielectric that makes surface contact between the two housings, thereby ensuring a stable ground condition, thereby helping to ensure stable radiation performance of the antenna and slimming of the electronic device not only in the extended state but also in the extended state.

[0016] In addition, various effects may be provided, either directly or indirectly, through this document.

[0017] The effects that can be obtained from the present disclosure are not limited to the effects mentioned above, and other effects that are not mentioned can be clearly understood by a person having ordinary skill in the art to which the present disclosure belongs from the description below.

For example, when the electronic device (101) includes the main processor (121) and the auxiliary processor (123), the auxiliary processor (123) may be configured to use less power than the main processor (121) or to be specialized for a given function. The auxiliary processor (123) may be implemented separately from the main processor (121) or as a part thereof.

[0047] The auxiliary processor (123) may control at least a portion of functions or states associated with at least one component (e.g., a display module (160), a sensor module (176), or a communication module (190)) of the electronic device (101), for example, on behalf of the main processor (121) while the main processor (121) is in an inactive (e.g., sleep) state, or together with the main processor (121) while the main processor (121) is in an active (e.g., application execution) state.

The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a 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 a wired communication module (194) (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) 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 types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0062] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of 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) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (192) can support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna.

Each of the external electronic devices (102 or 104) may be the same or a different type of device as the electronic device (101). According to one embodiment, all or part of the operations executed in the electronic device (101) may be executed in one or more of the external electronic devices (102, 104, or 108). For example, when the electronic device (101) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (101) may, instead of or in addition to executing the function or service itself, request one or more external electronic devices to perform the function or at least a part of the service.

In one embodiment, the electronic device (200) can include a second rear cover (223) coupled with a second extension member (222) extended from a second side member (221) and a window cover (224) coupled with a portion of the second rear cover (223).

[0100] 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 a manner of being bent into the first space (2101) together with the support member (240), thereby being arranged so as not to be visible 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.

[0101] According to various embodiments, at least a portion of the second housing (220) may be transitioned to a pull-out state in which it is moved outwardly from the first housing (210) at least partially along the first direction (direction ①) by driving the drive motor (260). In one embodiment, the flexible display (230) may be supported by the support bracket (225) in the pull-out state of the electronic device (200) (state of FIG. 5b) and may be moved together with the support member (240), such that a portion inserted into the first space (2101) may be exposed so as to be at least partially visible from the outside. 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 expanded beyond the first display area exposed to the outside.

[0102] According to various embodiments, the electronic device (200) may include at least one dielectric (410) disposed on at least a portion of the second rear cover (223) facing the first extension member (212). In one embodiment, the at least one dielectric (410) may be positioned on at least a portion of an overlapping area (400a) that overlaps at least the second rear cover (223) in a pulled-out state. In one embodiment, the at least one dielectric (410) may be disposed in a manner that is attached to the second rear cover (223). In one embodiment, the at least one dielectric (410) may be attached in a manner that is received in a recess (2231) formed lower than a surface of the second rear cover (223). In one embodiment, at least one dielectric (410) is attached to the recess (2231) and positioned higher than the outer surface of the second rear cover (223), so that when the first housing (210) and the second housing (220) are coupled, the dielectric (410) may be positioned to come into contact with the first extension member (212) of the first housing (210). This mounting structure of the dielectric (410) through the recess (2231) can reduce the phenomenon of the dielectric (410) randomly flowing due to friction or being separated from the overlapping area (400a) during the insertion / withdrawal operation of the electronic device (200), and can help prevent the inflow of external foreign substances and improve operational reliability by forming the thickness of the dielectric (410) thicker while minimizing the coupling gap (d1) between the two housings (210, 220) as much as possible. For example, at least one dielectric (410) may be formed with a thickness to prevent or reduce scratches caused by contact between the first housing (210) and the second housing (220) in a withdrawn state. In one embodiment, the at least one dielectric (410) may include at least one of nylon, polyester, adhesive tape, or sponge. In some embodiments, the at least one dielectric (410) may be replaced with a conductive tape having a certain thickness.

[0103] FIG. 6a is a schematic diagram of a second housing according to various embodiments of the present disclosure. FIG. 6b is a diagram illustrating a state in which a dielectric is arranged in a second housing according to various embodiments of the present disclosure.

[0104] Referring to FIGS. 6A and 6B , the second housing (220) may include a second side member (221) forming at least a portion of the exterior of the electronic device (200) and a second rear cover (223) coupled with at least a portion of the second side member (221). In one embodiment, the second rear cover (223) and the second side member (221) may be formed of a conductive material (e.g., metal). In one embodiment, the second rear cover (223) may be formed integrally with the second side member (221). In one embodiment, the second housing (220) may include a first conductive portion (310) disposed through a first segment (321) and / or a second segment (322) that are spaced apart from each other in the second side member (221). In one embodiment, the first conductive portion (310) may be used as a part of the exterior of a side surface (e.g., the fourth side surface (2211) and / or the fifth side surface (2212)) of the electronic device (200) that is visible from the outside. In one embodiment, the first conductive portion (310) may be operated as an antenna (A) configured to transmit or receive a wireless signal in a designated frequency band (e.g., about 600 MHz to 1 GHz) via a communication circuit (e.g., the wireless communication module (192) of FIG. 1) disposed inside the electronic device (200). In some embodiments, the second housing (220) may include a second conductive portion (311) disposed through a third segment (323) that is spaced apart from the second segment (322). For example, the second conductive portion (311) may also be used as an antenna.

[0105] According to various embodiments, the second rear cover (223) may include a recess (2231) formed in at least a portion of an overlapping area (e.g., an overlapping area (400a) of FIG. 7A) that faces a first extension member (e.g., a first extension member (212) of FIG. 7A) of a first housing (e.g., a first housing (210) of FIG. 7A) in an extended state of the electronic device (200). In one embodiment, the second housing (220) may include a dielectric (410) that is arranged in a manner that is partially seated in the recess (2231). In one embodiment, the dielectric (410) is formed to have a size that substantially corresponds to the overlapping area (e.g., an overlapping area (400a) of FIG. 7A) and may be seated in the recess (2231).

[0106] FIGS. 7A and 7B are diagrams illustrating the back and front surfaces of an electronic device including a dielectric in an extended state according to various embodiments of the present disclosure. FIG. 7C is a cross-sectional view of a portion of the electronic device taken along line 7C-7C of FIG. 7A according to various embodiments of the present disclosure.

[0107] In describing the electronic device (200) of FIGS. 7A to 7C, the same components as those of the second housing (220) of FIGS. 6A and 6B are given the same reference numerals, and a detailed description thereof may be omitted.

[0108] Referring to FIGS. 7A to 7C, the electronic device may include a first housing and a second housing slidably coupled to the first housing. In one embodiment, the first housing (220) may include a third conductive portion (312) disposed through a fourth segment (324) and a fifth segment (325) spaced apart from the first side member (211). In one embodiment, the third conductive portion (312) may be used as a part of the exterior of a side surface (e.g., the first side surface (2111)) of the electronic device (200) so as to be visible from the outside. In one embodiment, the third conductive portion (312) may be configured to operate as another antenna (A1) configured to transmit or receive a wireless signal in a designated frequency band (e.g., about 600 MHz to 1 GHz) via a communication circuit (e.g., the wireless communication module (192) of FIG. 1) disposed within the electronic device (200). In some embodiments, the antenna (A) and the other antenna (A1) may be configured to operate in different frequency bands.

[0109] According to various embodiments, the electronic device (200), in a withdrawn state, may include an overlapping area (400a) where the first housing (210) and the second housing (220) overlap. In one embodiment, the overlapping area (400a) may be set to have a width (W1) substantially equal to the width of the electronic device (200) and a specified length (W2) in a direction parallel to the length of the electronic device (200) (e.g., y-axis direction). In one embodiment, the overlapping area (400a) may include an area where, in a withdrawn state, the first extension member (212) of the first housing (210) and the second rear cover (223) of the second housing (220) face each other. In one embodiment, the overlapping area (400a) may be determined by the width (W1) and / or the length (W2) of the second rear cover (223), which is not exposed to the outside and is introduced into the interior of the first housing (210) in the withdrawn state. In some embodiments, the overlapping area (400a) may include an overlapping area where, in the withdrawn state, the second side (2112) and the third side (2113) of the first housing (210) face the fifth side (2212) and the sixth side (2213) of the second housing (220), respectively. For example, the length (W2) of the second rear cover (223) may be determined in consideration of a smooth sliding operation of the electronic device (200) and an efficient layout design of surrounding structures.

[0110] According to various embodiments, the dielectric (410) may be positioned in at least a portion of an overlapping area (400a) that overlaps at least the second rear cover (223) in the pulled-out state of the electronic device (200). In one embodiment, the dielectric (410) may be attached in a manner that it is received in a recess (2231) formed lower than a surface of the second rear cover (223). In some embodiments, the dielectric (410) may be attached to the surface of the second rear cover (223) without the recess (2231). In one embodiment, the dielectric (410) may be positioned to contact the first extension member (212) of the first housing (210) when the first housing (210) and the second housing (220) are coupled. Therefore, the dielectric (410) can help reduce the degradation of the radiation performance of the antenna (A) and / or another antenna (A1) even in the pulled-out state by inducing a stable ground condition through a stable coupling (or electrical connection) between the two housings (210, 220).

[0111] FIGS. 7d ​​and 7e are modified embodiments of FIG. 7c according to various embodiments of the present disclosure.

[0112] Referring to FIG. 7d, the dielectric (410) may be attached to the first extension member (212) of the first housing (210) and may be arranged in such a manner as to be in contact with the second rear cover (223). In this case, the first extension member (212) may include a recess (2121) formed lower than the outer surface of the first extension member (212), and the dielectric (410) may be arranged in such a manner as to be seated in the recess (2121).

[0113] Referring to FIG. 7E, in the configuration of FIG. 7A, the dielectric (410) may be attached to the recess (2231) of the second rear cover (223) via an adhesive member (P) (e.g., an adhesive layer). In one embodiment, the dielectric (410) may be moved in a manner of contacting the first extension member (212), so that a frictional force may be generated. This frictional force may cause a driving loss of the drive motor (e.g., the drive motor (260) of FIG. 4). In one embodiment, the electronic device (200) may further include a friction-reducing coating layer (C) attached to the dielectric (410) to reduce the frictional force due to the contact of the dielectric (410) between the dielectric (410) and the first extension member (212). In one embodiment, the friction-reducing coating layer (C) may include a Teflon coating layer or a hard coating layer. In some embodiments, the dielectric (410) may be formed by stacking at least two dielectrics having different permittivities.

[0114] FIGS. 8A and 8B are drawings comparing changes in current distribution of an electronic device depending on the presence or absence of a dielectric in a withdrawal state according to various embodiments of the present disclosure.

[0115] FIG. 8a is a comparative example of an electronic device (200) to which a dielectric (410) is not applied. In the withdrawn state, it can be confirmed that the external current of the second housing (220) and the internal current of the first housing (210) flow in opposite directions. This may mean that the radiation performance is deteriorated by generating a parasitic resonant frequency in the operating frequency band (e.g., low band) of the antenna (A).

[0116] FIG. 8b illustrates an electronic device (200) according to an exemplary embodiment of the present disclosure to which a dielectric (410) is applied. In the extended state, it can be confirmed that the external current of the second housing (220) and the internal current of the first housing (210) flow in the same direction. This may mean that even when the electronic device (200) is extended, the first housing (210) and the second housing (220) can satisfy stable ground conditions through the dielectric (410), and can help improve the radiation performance of the antenna (A).

[0117] FIG. 9A is a comparative example diagram showing the current distribution of an electronic device in a pulled-out state when no dielectric is present. FIG. 9B is a comparative example diagram showing the current distribution of an electronic device in a pulled-out state when a point-contact type conductive contact is placed. FIG. 9C is a diagram showing the current distribution of an electronic device in a pulled-out state when a dielectric is placed, according to various embodiments of the present disclosure.

[0118] FIG. 9a is a comparative example of an electronic device (200) to which a dielectric (410) is not applied. In the pulled-out state, it can be confirmed that a current distribution appears in the area (area 901) where the antenna (A) is positioned, and at the same time, a current distribution through unstable coupling appears across the entire area (area 902) of the first housing (210) and the second housing (220). This may mean that a parasitic resonant frequency may be generated in the operating frequency band (e.g., low band) of the antenna (A), which may deteriorate the radiation performance.

[0119] FIG. 9b is a comparative example in which a dielectric (410) is not applied and a point-contact type conductive contact is applied to both sides of an electronic device (200). In the pulled-out state, it can be confirmed that a current distribution appears in the area (area 901) where the antenna (A) is positioned, and at the same time, a current distribution through unstable coupling appears in the overlapping areas (areas 903 and 904) of both sides of the first housing (210) and the second housing (220) (e.g., the part where the conductive contact is arranged). Although this is an improvement over the case of FIG. 9a, it may mean that the radiation performance is deteriorated because a parasitic resonant frequency is still generated in the operating frequency band (e.g., low band) of the antenna (A).

[0120] FIG. 9c illustrates an electronic device (200) according to an exemplary embodiment of the present disclosure to which a dielectric (410) is applied. It can be seen that, in the extended state, a current distribution appears only in the region (region 901) where the antenna (A) is positioned. This may mean that even when the electronic device (200) is extended, the first housing (210) and the second housing (220) can satisfy stable ground conditions through the dielectric (410) and help secure the radiation performance of the antenna (A).

[0121] FIG. 10 is a graph comparing the radiation performance of an antenna with and without a dielectric in a withdrawal state according to various embodiments of the present disclosure.

[0122] Referring to Fig. 10, when the antenna (A) is operated in a designated frequency band (e.g., approximately 600 MHz to 1 GHz), in the pulled-out state, when no dielectric (410) is applied between the first housing (210) and the second housing (220) as in Fig. 9a (graph 1001), it can be confirmed that a parasitic resonant frequency of approximately 720 MHz is generated, and when a conductive contact of the point contact type is applied as in Fig. 9b (graph 1002), it can be confirmed that a parasitic resonant frequency of approximately 930 MHz is still generated. This may mean that the radiation performance of the antenna is deteriorated.

[0123] On the other hand, as shown in FIG. 9c, when a dielectric (410) is applied between the first housing (210) and the second housing (220) according to an embodiment of the present invention (graph 1003), it can be confirmed that the parasitic resonance frequencies described above are removed from the operating frequency band of the antenna (A). This may mean that even when the electronic device (200) is in a withdrawn state, the first housing (210) and the second housing (220) can satisfy a stable ground condition through the dielectric (410) and help secure the radiation performance of the antenna (A). Here, the meaning of 'removal' of the parasitic resonance frequency may mean that the parasitic resonance frequency is moved to a band (out band) other than the operating frequency band of the antenna (A) through the stable coupling of the first and second housings (210, 220) through the dielectric (410).

[0124] FIG. 11 is a graph comparing the radiation performance of an antenna according to changes in the overlapping area of ​​two housings and the presence or absence of a dielectric in a withdrawal state according to various embodiments of the present disclosure.

[0125] Referring to Fig. 11, when the antenna (A) is operated in a designated frequency band (e.g., about 600 MHz to 1 GHz), in the extended state, the width (e.g., width (W1) of Fig. 7a) of the overlapping area (400a) of the first housing (210) and the second housing (220) is set to 65 mm, the length (e.g., length (W2) of Fig. 7a) is set to 5 mm, and the dielectric (410) is not applied (graph 1101), it can be confirmed that a parasitic resonant frequency of about 660 MHz is generated. In one embodiment, when the length (W2) of the overlapping region (400a) is sequentially increased to 7 mm (graph 1102) and 9 mm (graph 1103) while the dielectric (410) is not applied and the width (W1) of the overlapping region (400a) is fixed at 65 mm, it can be confirmed that the parasitic resonant frequency is low-shifted. This may mean that when the coupling area of ​​the overlapping region (400a) of the first housing (210) and the second housing (220) increases in the pulled-out state, the parasitic resonant frequency can be removed from the operating frequency band of the antenna (A). However, there is a limitation in that the increase in the overlapping region (400a) restricts the operation of the first housing (210) and the second housing (220) and makes it difficult to design the layout and structures arranged inside the electronic device (200).

[0126] On the other hand, according to an exemplary embodiment of the present disclosure, when the width (W1) of the overlapping area (400a) of the first housing (210) and the second housing (220) in the withdrawal state is set to 65 mm and the length (W2) is set to 5 mm, and the dielectric (410) is applied (graph 1104), it can be confirmed that the parasitic resonance frequency is removed from the operating frequency band of the antenna (A).

[0127] For example, in the withdrawal state, even if the first housing (210) and the second housing (220) have a relatively small overlapping area (400a), the parasitic resonance frequency can be efficiently removed through the dielectric (410), which can mean that smooth insertion / withdrawal operation of the electronic device (200) can be induced and that it can help in the efficient layout design of the surrounding structure.

[0128] FIG. 12 is a graph comparing the radiation performance of an antenna according to changes in the area of ​​a dielectric in a withdrawal state according to various embodiments of the present disclosure.

[0129] Referring to FIG. 12, when the antenna (A) is operated in a designated frequency band (e.g., about 600 MHz to 1 GHz), it can be confirmed that a parasitic resonant frequency of about 720 MHz is generated when the dielectric (410) is not applied between the first housing (210) and the second housing (220) in the extended state (graph 1201). In addition, when the width (e.g., width (W1) of FIG. 7a) of the overlapping area (400a) of the first housing (210) and the second housing (220) is set to 65 mm and the length (e.g., length (W2) of FIG. 7a) is set to 5 mm in the extended state, and a dielectric (410) having a width of 5 mm and a length of 5 mm is applied to the overlapping area (400a) (graph 1202), it can be confirmed that a parasitic resonant frequency is still generated within the operating frequency band of the antenna (A). In such cases, the low band parasitic components do not completely disappear, but they may be at an applicable level if switching through matching circuits such as passive elements (e.g. capacitors or inductors) is considered.

[0130] On the other hand, when a dielectric (410) having a width of 65 mm and a length of 5 mm is applied to the overlapping region (400a) so as to have the same size as the area of ​​the overlapping region (400a) according to an exemplary embodiment of the present disclosure (graph 1203), it can be confirmed that the parasitic resonance frequency is eliminated from the operating frequency band of the antenna (A). This may mean that the elimination of the parasitic resonance frequency may be determined depending on the size of the dielectric (410) placed in the overlapping region (400a).

[0131] FIG. 13 is a graph comparing the radiation performance of an antenna according to changes in dielectric constant in a withdrawal state according to various embodiments of the present disclosure.

[0132] Referring to Fig. 13, when the antenna (A) is operated in a designated frequency band (e.g., approximately 600 MHz to 1 GHz), in the extended state, when no dielectric (410) is applied between the first housing (210) and the second housing (220) (graph 1301), it can be confirmed that a parasitic resonant frequency of approximately 720 MHz is generated. In addition, in the extended state, when a dielectric (e.g., FR-4) having a permittivity of 4.3 is applied to the overlapping region (400a) of the first housing (210) and the second housing (220) (graph 1302), although a parasitic resonant frequency is generated within the operating frequency band of the antenna (A), it can be shifted to a level where it can be eliminated through a matching element (e.g., a passive element).

[0133] On the other hand, when a dielectric (410) with a permittivity of 12 is applied to the overlapping region (400a), it can be confirmed that the parasitic resonance frequency is eliminated from the operating frequency band of the antenna (A). This may mean that the elimination of the parasitic resonance frequency can be determined depending on the permittivity of the dielectric (410) placed in the overlapping region (400a).

[0134] FIG. 14 is a graph comparing the radiation performance of different antennas with and without a dielectric in a withdrawal state according to various embodiments of the present disclosure.

[0135] Referring to FIG. 14, when another antenna (A1) using the third conductive portion (312) arranged in the first housing (210) of FIG. 7a is operated in a designated frequency band (e.g., about 600 MHz to 1 GHz), in the pulled-out state, when the dielectric (410) is not applied to the overlapping area (400a) of the first housing (210) and the second housing (220) (graph 1401), a parasitic resonant frequency of about 690 MHz is generated, whereas when the dielectric (410) is applied between the first housing (210) and the second housing (220) according to an exemplary embodiment of the present disclosure (graph 1402), it can be confirmed that the parasitic resonant frequency is eliminated in the operating frequency band of another antenna (A1). This may mean that when a dielectric (410) is placed in the overlapping area (400a) of the first housing (210) and the second housing (220) in the withdrawal state of the electronic device (200), the radiation performance of not only the antenna (A) placed in the second housing (220) but also another antenna (A1) placed in the first housing (210) is improved.

[0136] FIGS. 15A and 15B are drawings of an electronic device showing a dielectric arrangement structure in a withdrawal state according to various embodiments of the present disclosure.

[0137] In describing the electronic device (200) of FIGS. 15a and 15b, the same reference numerals are given to components that are substantially the same as those of the electronic device (200) of FIG. 7a, and a detailed description thereof may be omitted.

[0138] As illustrated in FIG. 15a, the electronic device (200) may include an overlapping area (400a) in which, in a withdrawn state, the first extension member (212) of the first housing (210) and the second rear cover (223) of the second housing (220) overlap. In one embodiment, the electronic device (200) may include a dielectric (411) (e.g., the dielectric (410) of FIG. 7a) disposed in the overlapping area (400a). In one embodiment, the dielectric (411) may be formed to have a size smaller than the area of ​​the overlapping area (400a).

[0139] As illustrated in FIG. 15b, the electronic device (200) may include a plurality of dielectrics (412, 413, 414) arranged in an overlapping area (400a) between the first extension member (212) of the first housing (210) and the second rear cover (223) of the second housing (220) in an extended state. In one embodiment, the plurality of dielectrics (412, 413, 414) may be arranged at a specified interval in the overlapping area (400a). In one embodiment, the plurality of dielectrics (412, 413, 414) may have the same or different permittivities. As illustrated, the plurality of dielectrics (412, 413, 414) illustrates three dielectrics, but two or four or more dielectrics may be arranged at a specified interval.

[0140] In some embodiments, some of the dielectrics may be positioned such that they are attached to the second rear cover, and the remaining dielectrics are attached to the first extension member (212). In such a case, in the extended state, some of the dielectrics may be positioned so as to overlap or not overlap at least a portion of the remaining dielectrics.

[0141] FIG. 16A is a plan view and a side view of an electronic device showing a state in which dielectrics are arranged on a side according to various embodiments of the present disclosure. FIG. 16B is a perspective view of a first housing in which the dielectrics of FIG. 16A are arranged according to various embodiments of the present disclosure. FIG. 16C is a perspective view of a first housing showing a modified embodiment of FIG. 16B according to various embodiments of the present disclosure.

[0142] In describing the electronic device (200) of FIGS. 16a to 16c, the same reference numerals are given to components that are substantially the same as those of the electronic device (200) of FIG. 7a, and a detailed description thereof may be omitted.

[0143] Referring to FIGS. 16a and 16b, the electronic device (200), in a withdrawn state, may include a first dielectric (415) and a second dielectric (416) disposed on opposite sides, respectively, in an area corresponding to an overlapping area (400a) between the first housing (210) and the second housing (210). In one embodiment, the first dielectric (415) may be disposed in such a manner that it is attached to an inner side (2112a) corresponding to the second side (2112) of the first housing (210) and an inner side (2113a) corresponding to the third side (2113). For example, although not shown, the first dielectric (415) and the second dielectric (416) may be arranged in a manner in which they are at least partially accommodated in recesses formed in the inner side (2112a) corresponding to the second side (2112) of the first housing (210) and the inner side (2113a) corresponding to the third side (2113). Accordingly, in the pulled-out state of the electronic device (200), the first dielectric (415) contacts the fifth side (2212) of the second side member (221) of the second housing (220), and the second dielectric (416) contacts the sixth side (2213) of the second side member (221) of the second housing (220), thereby inducing stable coupling. In some embodiments, the first dielectric (415) and / or the second dielectric (416) may be disposed on the fifth side (2212) and / or the sixth side (2213) of the second housing (220), in an area corresponding to the overlapping area (400a) between the first housing (210) and the second housing (210).

[0144] Referring to FIG. 16c, in the configuration of FIG. 16b, the first dielectric (415) and the second dielectric (416) may be connected, and a third dielectric (417) may be further included, which is arranged in the first extension member (212) in the first space (2101) of the first housing (210).
