[0072] According to one embodiment, as the functions provided by an electronic device (101) become more diverse, the number and types of electrical components mounted within the electronic device (101) may increase. This necessitates efficient utilization of the internal space of the electronic device (101) to arrange the electrical components.

[0076] FIG. 6 is a perspective view illustrating a circuit board assembly (310) connected to a side frame (271) of an electronic device (101) according to one embodiment. For convenience of explanation, some components other than the housing (271) and the circuit board assembly (310) are omitted.

[0077] Referring to FIGS. 5 and 6, the electronic device (101) can be understood as a plan view and a perspective view when viewed from the back. Accordingly, FIG. 5 can be understood as a drawing of the electronic device (101) with the back plate (e.g., the back plate (280) of FIG. 4) removed, and the housing (271) and the circuit board assembly (310) viewed from the back in the front direction (i.e., in the +z-axis direction). Hereinafter, descriptions such as “upper side,” “lower side,” “left side,” or “right side” described in this document are terms used for the convenience of explanation in the drawings, and are not limited to a specific location.

[0078] According to one embodiment, the side frame (271) may form a side appearance of the electronic device (101). The side frame (271) may be composed of at least one material selected from the group consisting of metal and synthetic resin. The side frame (271) made of a metal material may form an antenna.

[0080] According to one embodiment, a metal member (305) may be provided on the inner side of the side frame (271). The metal member (305) may be attached to the inner surface of the side frame (271). The metal member (305) and the side frame (271) may form a laminated structure. The metal member (305) may also be implemented as an integral part with the side frame (271).

[0081] According to one embodiment, the metal member (305) may be composed of a material having conductivity. For example, the metal member (305) may be composed of a metal material.

[0082] According to one embodiment, the metal member (305) may be provided to radiate an antenna signal from the antenna feed structure (300). The metal member (305) may radiate an antenna signal based on a current supplied from the feed unit (301).

[0083] According to one embodiment, the side frame (271) and the metal member (305) may include an insulating member (273). The insulating member (273) may be formed of a non-conductive material provided in a space where a portion of the side frame (271) is removed. The insulating member (273) may include a first insulating member (273a) provided at an arbitrary point on the first side frame (271a). The insulating member (273) may include a second insulating member (273b) provided at an arbitrary point on the second side frame (271b). Although not shown, the insulating member (273) may further include insulating members (not shown) provided at arbitrary points on the side frame (271) as needed.

[0084] According to one embodiment, the circuit board assembly (310) may be arranged along the side frame (271). The circuit board assembly (310) may be arranged along the first side frame (271a) and the second side frame (271b). That is, the back surface of the circuit board assembly (310) may be arranged to face the side frame (271). Through this, integration of electrical components mounted on the front case (272) may be achieved.

[0085] According to one embodiment, the circuit board assembly (310) can be bent near an edge where the first side frame (271a) and the second side frame (271b) meet. In order for the circuit board assembly (310) to be bent near the edge, the circuit board assembly (310) can include a flexible printed circuit board (350) (hereinafter, referred to as FPCB).

[0086] According to one embodiment, the FPCB (350) can be bent near the corner where the first side frame (271a) and the second side frame (271b) meet.

[0087] According to one embodiment, the circuit board assembly (310) may include a first printed circuit board (320) (hereinafter referred to as a first PCB), a second printed circuit board (330) (hereinafter referred to as a second PCB), and an FPCB (350). The first PCB (320) and the second PCB (330) may be connected to both sides of the FPCB (350).

[0088] According to one embodiment, an antenna pattern (not shown) may be provided on the front or back surface of the circuit board assembly (310). The antenna pattern may be formed of a conductive member of the circuit board assembly (310). The antenna pattern may be freely designed and changed within a space formed inside a rear case (e.g., the second support member (260) of FIG. 4). For example, the antenna pattern may be provided on the front and back surfaces of the first PCB (320), or on the front and back surfaces of the second PCB (330).

[0089] According to one embodiment, a circuit board assembly (310) can connect a radiating member (305) included in an antenna feed structure (300) and a printed circuit board (e.g., a printed circuit board (240) of FIG. 3). A connecting member (e.g., a connecting member (337) of FIG. 8) provided at one end of the circuit board assembly (310) can be connected to a connector (241) provided on the printed circuit board (240).

[0090] According to one embodiment, a screw (380) may be provided to secure the circuit board assembly (310) to the radiating member (305). The screw (380) may be fastened to the radiating member (305) by penetrating a point of the circuit board assembly (310), a metal sheet (e.g., a metal sheet (370) of FIG. 7), and a casing member (303). The screw (380) may be secured to the radiating member (305) by penetrating a through hole (e.g., a through hole (360) of FIG. 7) provided on the back surface of the first PCB (320).

[0091] According to one embodiment, an antenna feeding structure (300) may be formed by fixing a circuit board assembly (310), a metal sheet (370), and a casing member (303) to a radiating member (305) by a screw (380). The antenna feeding structure (300) may include a feeding unit (e.g., a feeding unit (301) of FIG. 7) for supplying a current required to radiate a wireless signal. The feeding unit (301) may be implemented as at least a portion of the circuit board assembly (310) and the metal sheet (370). The feeding unit (301) may include a feeding point or a feeding line.

[0092] According to one embodiment, at least one screw (380) may be provided. The screw (380) may be provided to fix the first PCB (320) to the radiating member (305) as illustrated. The screw (380) may include a first screw or a second screw. In addition, without being limited to what is illustrated, the screw (380) may further include at least one screw (not illustrated) to fix the second PCB (330) to the radiating member provided on the second side frame (271b). The second PCB (330) may further be provided with a through hole for the at least one screw to pass through. In the present disclosure, it will be assumed that the screw (380) is provided to fasten the first PCB (320) of the circuit board assembly (310) to the metal member (305).

[0093] According to one embodiment, the screw (380) may penetrate vertically through the circuit board assembly (310) and be fastened to the metal member (305).

[0094] According to one embodiment, the circuit board assembly (310) may be arranged to be inclined at a predetermined angle with respect to the side frame (271). The predetermined angle may range from, for example, 10° to 20°. That is, the first to third angles (θ1, θ2, θ3) below may range from 10° to 20°. For example, the angle formed by the first PCB (320) with the first side frame (271a) may be defined as the first angle (θ1). For example, the angle formed by the second PCB (330) with the second side frame (271a) may be defined as the second angle (θ2). For example, the angle formed by the FPCB (350) with the edge where the first side frame (271a) and the second side frame (271b) meet may be defined as the third angle (θ3).

[0095] In one embodiment, the first angle (θ1), the second angle (θ2), and the third angle (θ3) may be equal.

[0096] According to one embodiment, at least two of the first angle (θ1), the second angle (θ2) and the third angle (θ3) may be equal.

[0097] For example, among the first angle (θ1), the second angle (θ2), and the third angle (θ3), the first angle (θ1) and the second angle (θ2) may be the same, and the third angle (θ3) may be different from the first angle (θ1) and the second angle (θ2).

[0098] For example, among the first angle (θ1), the second angle (θ2), and the third angle (θ3), the second angle (θ2) and the third angle (θ3) may be the same, and the second angle (θ2) may be different from the first angle (θ1) and the third angle (θ3).

[0099] For example, among the first angle (θ1), the second angle (θ2), and the third angle (θ3), the second angle (θ2) and the third angle (θ3) are the same, and the first angle (θ1) may be different from the second angle (θ2) and the third angle (θ3).

[0100] In one embodiment, the first angle (θ1), the second angle (θ2), and the third angle (θ3) can all be different.

[0101] According to one embodiment, the first angle (θ1), the second angle (θ2), and the third angle (θ3) can have free values ​​within a preset range, but for the convenience of the following description, it is assumed that the circuit board assembly (310) is tilted at the same angle with respect to the side frame (271). That is, it is assumed that the first angle (θ1), the second angle (θ2), and the third angle (θ3) are all the same.

[0102] According to one embodiment, since the circuit board assembly (310) is tilted at a predetermined angle, physical interference between a fastening device (not shown) (e.g., a screw driver) for fastening a screw (380) and peripheral devices mounted on the electronic device (101) (e.g., electrical components, a casing member (303) (e.g., a front case (272) or a rear case (260)), or a housing (e.g., a support bracket (270) of FIG. 4)) can be minimized. As a result, the ease of fastening the circuit board assembly (310) and the housing (e.g., the support bracket (270) of FIG. 4)) can be improved.

[0103] For example, as the first to third angles (θ1, θ2, θ3) increase, the physical interference between the circuit board assembly (310) and the peripheral devices may decrease. Accordingly, as the first to third angles (θ1, θ2, θ3) increase, the ease of fastening the circuit board assembly (310) may increase.

[0104] For example, as the first to third angles (θ1, θ2, θ3) increase, the space for the screw (380) to penetrate the circuit board assembly (310) and be fastened to the radiating member (305) may decrease. Taking this into account, the first to third angles (θ1, θ2, θ3) may be substantially 10° to 20°.

[0105] According to one embodiment, the lengths of the first open end (351) and the second open end (353) of the FPCB (350) may be different so that the circuit board assembly (310) is arranged to be inclined relative to the side frame (271). The length (w1) of the first open end (351) may be longer than the length (w2) of the second open end (353).

[0106] According to one embodiment, the difference between the length (w1) of the first open end (351) and the length (w2) of the second open end (353) can vary in correspondence to the first angle (θ1, θ2, θ3). Since the FPCB (350) is made of a flexible material, the first open end (351) and the second open end (353) can expand or contract within the movable range.

[0107] For example, as the first to third angles (θ1, θ2, θ3) increase, the difference between the length (w1) of the first open end (351) and the length (w2) of the second open end (353) may increase.

[0108] For example, as the first to third angles (θ1, θ2, θ3) become smaller, the difference between the length (w1) of the first open end (351) and the length (w2) of the second open end (353) may decrease.

[0109] For example, as the first to third angles (θ1, θ2, θ3) approach 0, that is, as the circuit board assembly (310) is arranged parallel to the side frame (271), the length (w1) of the first open end (351) and the length (w2) of the second open end (353) may be substantially equal.

[0110] According to one embodiment, since the circuit board assembly (310) is arranged to be inclined at a predetermined angle (e.g., first angle to third angle (θ1, θ2, θ3)) with respect to the side frame (271), a feeding point can be provided at a point adjacent to the side frame (271). As the feeding point is arranged at a point adjacent to the side frame (271), the distance between the feeding point and electrical components adjacent to the antenna feeding structure (300) increases, thereby minimizing electrical interference. Accordingly, the radiation performance of the antenna can be improved.

[0111] Fig. 7 is a cross-sectional view of an electronic device (e.g., the electronic device (101) of Fig. 1) according to one embodiment. Fig. 7 may be understood as a view taken along the line AA' of Fig. 5, viewed in the +x-axis direction.

[0112] Referring to FIG. 7, the antenna feed structure (300) may include a side frame (e.g., a side frame (271) of FIG. 5), a circuit board assembly (e.g., a circuit board assembly (310) of FIG. 5), a metal sheet (370), and a screw (380).

[0113] According to one embodiment, the casing member (303) may be formed as at least a portion of the front case (e.g., the front case (272) of FIG. 4) or may be provided separately on one surface of the front case (272). The casing member (303) may be provided to mount elements constituting the antenna feed structure (300) (e.g., a circuit board assembly (310) or a metal sheet (370)). One surface of the casing member (303) may be in contact with one surface of the side frame (271).

[0114] According to one embodiment, a metal sheet (370) may be arranged on the inner surface of the casing member (303) in contact with the side frame (271). The metal sheet (370) may be provided to prevent a passive inter-modulation distortion (hereinafter referred to as PIMD) phenomenon. PIMD may be understood as a phenomenon in which two or more transmission signal frequencies interfere with each other due to nonlinearity of passive elements in wireless communication, thereby generating noise. As a way to minimize the PIMD phenomenon, a metal sheet (370) made of a metal material for minimizing nonlinearity between metals may be arranged on the inner surface of the casing member (303).

[0115] According to one embodiment, the metal sheet (370) can be attached to the inner surface of the casing member (303). The metal sheet (370) and the inner surface of the casing member (303) can be attached through an ultrasonic bonding method.

[0116] According to one embodiment, the metal sheet (370) may be manufactured by plating a metal member with a gold-cobalt (Au-Co) material. The size of the metal sheet (370) may be implemented as, for example, 2 mm in width and 2 mm in length. However, the size of the area occupied by the metal sheet (370) is not limited thereto, and may be determined in various ways in consideration of the manufacturing process, the attachment point, and surrounding components.

[0117] According to one embodiment, one surface of the metal sheet (370) may be in contact with the inner surface of the casing member (303). The other surface opposite to the one surface may be in contact with at least a portion of the surface of the first PCB (320). Here, the surface where the metal sheet (370) is in contact with the casing member (303) may be defined as the first surface (e.g., the first surface (371) of FIG. 9), and the other surface where the metal sheet (370) is in contact with at least a portion of the surface of the first PCB (320) may be defined as the second surface (e.g., the second surface (373) of FIG. 9).

[0118] According to one embodiment, in order to place the first PCB (320) at a predetermined angle (e.g., a first angle (θ1)) with respect to the first side frame (271a), the first side (371) and the second side (373) of the metal sheet (370) may form a predetermined angle. The predetermined angle may be, for example, the same as the first angle (θ1).

[0119] According to one embodiment, the first side (371) and the second side (373) of the metal sheet (370) form a predetermined angle, so that the first PCB (320) can be arranged to be inclined at a first angle (θ1) with respect to the first side frame (271a).

[0120] According to one embodiment, the back surface of the first PCB (320) may be placed on the second side (373) of the metal sheet (370).

[0121] According to one embodiment, a ring-shaped washer (361) covering the outer surface of a through hole (e.g., a through hole (360) of FIG. 8) may be provided on the back surface of the first PCB (320). The washer (361) may have a shape similar to a flat washer. The washer (361) may be made of a metal material and may have conductivity.

[0122] According to one embodiment, the washer (361) can electrically connect the first PCB (320) and the metal sheet (370). Since the first PCB (320) includes the washer (361), the first PCB (320) and the metal sheet (370) can be stably connected. In addition, the washer (361) can evenly distribute the force applied by the insertion of the screw (380). As a result, the washer (361) can prevent wear or damage due to contact with the metal sheet (370).

[0123] According to one embodiment, the washer (361) may have various shapes other than a ring-shaped shape. For example, the washer (361) may have a “C”-shaped shape with a predetermined point open. For example, the washer (361) may be implemented as a spring washer and have a twisted coil shape. In addition, the washer (361) may have various shapes corresponding to the shape of the washer.

[0124] According to one embodiment, at least one protrusion (e.g., protrusion (363) of FIG. 8) may be provided on the surface of the washer (361) that comes into contact with the metal sheet (370). The protrusion (363) may have a predetermined pattern and be formed on the surface. By providing the protrusion (363), a more stable electrical connection between the first PCB (320) and the metal sheet (370) can be provided.

[0125] According to one embodiment, the screw (380) can secure the first PCB (320) and the metal sheet (370) mounted on the casing member (303) to the first side frame (271a). The screw (380) can pass through the through hole (360) provided in the first PCB (320) and the metal sheet (370) to be fastened to the first side frame (271a).

[0126] According to one embodiment, the tip (hereinafter referred to as the screw tip) of the screw (380) may be fixed to a predetermined point of the first side frame (271a). If a screw thread is formed on the screw tip, a fastening member (not shown) having a shape corresponding to the screw thread may be provided at the predetermined point.

[0127] According to one embodiment, the screw (380) can be fastened in a vertical direction to the second surface (373) of the metal sheet (370). Therefore, the angle formed by the fastening direction (d) of the screw (380) and the second surface (373) can form substantially 90°.

[0128] According to one embodiment, the fastening direction (d) of the screw (380) and the auxiliary line p may form a predetermined angle (θ'). Here, the auxiliary line p may be parallel to the xy plane. The predetermined angle (θ') may be substantially equal to the first angle (θ1). However, the predetermined angle (θ') may be determined within the range of angles of the first angle to the third angle (θ1, θ2, θ3) depending on the arrangement angle of the circuit board assembly (310).

[0129] According to one embodiment, the antenna feed structure (300) may be mounted in the following manner. However, the present invention is not limited thereto, and the mounting order described below may be changed as needed.

[0130] According to one embodiment, a casing member (303) may be placed on an electronic device (101) placed on its back. Accordingly, the electronic device (101) may be placed with the casing member (303) in a state where the front plate (220) (e.g., the front plate (220) of FIG. 2) and the display (230) (e.g., the display (230) of FIG. 2) are placed on the bottom surface. One surface of the casing member (303) may be in contact with one surface of the radiating member (305) that is in contact with the inner surface of the side frame (271).

[0131] According to one embodiment, a metal sheet (370) may be arranged to contact the inner surface of the casing member (303). A first surface (371) of the metal sheet (370) may be arranged to contact the inner surface.

[0132] According to one embodiment, the second side (373) of the metal sheet (370) may be positioned to be in contact with the back surface of the first PCB (320). One side of a washer (361) covering a through hole (360) provided in the first PCB (320) may be in contact with the second side (373).

[0133] According to one embodiment, a screw (380) may pass through a through hole (360) provided in the first PCB (320) and penetrate the metal sheet (370) and the casing member (303) to be fixed to the first side frame (271a).

[0134] According to one embodiment, a feed portion (e.g., a feed portion (301) of FIG. 5) may be formed by some configuration in the antenna feed structure (300). For example, a metal sheet (370) and a washer (361) connected by a screw (380) may form the feed portion (301).

[0135] According to one embodiment, a washer (361) covering a through hole (360) provided in the first PCB (320) may be the starting point of the feeding portion (301). The starting point of the feeding portion (301) may be formed as a metal-to-metal contact in the antenna feeding structure (300).

[0136] According to one embodiment, since the circuit board assembly (310) is arranged to be inclined at a predetermined angle with respect to the side frame (271), a point for fastening a screw (380) for fastening the circuit board assembly (310) to the metal member (305) can form a predetermined angle (θ') with respect to a bottom surface (e.g., xy plane). Accordingly, the antenna feed structure (300) of the present disclosure can provide ease of fastening of the screw (380).

[0137] According to one embodiment, since the circuit board assembly (310) is arranged to be inclined at a predetermined angle with respect to the side frame (271), and the screw (380) is fastened in the vertical direction of the circuit board assembly (310), the starting point of the feeding part (301) can be formed at a point adjacent to the side frame (271). That is, the starting point of the feeding part (301) can be formed to be tilted toward the outside (e.g., +y direction) of the electronic device (101). As the starting point of the feeding part (301) is formed at a point adjacent to the side frame (271), the point of radiation from the antenna feeding structure (300) can be further from the electrical components mounted inside the electronic device (101). As a result, the radiation efficiency of the antenna can be increased, thereby providing improved antenna performance.

[0138] FIG. 8 is a front view showing a circuit board assembly (310) in a deployed state (e.g., the circuit board assembly (310) of FIG. 5) according to one embodiment. (a) of FIG. 8 is a front view of the circuit board assembly (310) in a deployed state, (b) is a symmetrical rear view of the first PCB (320) of the circuit board assembly (310), and (c) is an enlarged view of a through hole (360) provided on the rear surface of the first PCB (320) (e.g., the through hole (360) of FIG. 7).

[0139] Referring to FIG. 8, the circuit board assembly (310) may include a first PCB (320), a second PCB (330), and an FPCB (350). The circuit board assembly (310) may be formed of a rigid-flexible printed circuit board (R-FPCB) that is a combination of a rigid printed circuit board (R-PCB) and a flexible printed circuit board (F-PCB). The circuit board assembly (310) may be arranged at an angle with respect to the side frame (271) at a predetermined angle (e.g., the first angle (θ1) of FIG. 6).

[0140] According to one embodiment, electrical components may be mounted on the first PCB (320) or the second PCB (330). An electrical component having an antenna pattern engraved thereon may be mounted on the first PCB (320) or the second PCB (330). The electrical component may be mounted on the front or back surface of the first PCB (320). The electrical component may be mounted on the front or back surface of the second PCB (330).

[0141] According to one embodiment, the front surface of the first PCB (320) may be provided as a non-conductive surface, and the back surface may be provided as a conductive surface. Electrical wiring for the power supply unit (301) may be provided on the back surface of the first PCB (320).

[0142] According to one embodiment, the circuit board assembly (310) may include an FPCB (350) that can be bent near an edge where a first side frame (e.g., a first side frame (271a) of FIG. 5) and a second side frame (e.g., a second side frame (271b) of FIG. 5) meet.

[0143] According to one embodiment, a first PCB (320) and a second PCB (330) may be electrically and / or physically connected to opposite sides of an FPCB (350). For example, a first side (352) of the FPCB (350) and a second side (323) of the first PCB (320) may be connected. For example, a second side (354) of the FPCB (350) and a first side (331) of the second PCB (330) may be connected.

[0144] According to one embodiment, a through hole (360) through which a screw (e.g., screw (380) of FIG. 5) passes may be provided at a predetermined point of the first PCB (320). Although not shown, the through hole (360) may also be provided on the second PCB (330) as needed.

[0145] According to one embodiment, when a plurality of through holes (360) are provided, they may be formed at the same height on the first PCB (320). However, the present invention is not limited thereto, and the plurality of through holes (360) may be formed at different heights.

[0146] According to one embodiment, a ring-shaped washer (361) may be provided on the back surface of the first PCB (320) to cover the outer circumferential surface of the through-hole (360). The ring-shaped washer (361) may also be referred to as a sus-ring. If necessary, the washer (361) may be omitted.

[0147] According to one embodiment, at least one protrusion (363) may be provided at a predetermined point of the washer (361). The one or more protrusions (363) may be referred to as embossments. The one or more protrusions (363) may be provided on one surface of the washer (361) in a raised pattern having a predetermined shape. By providing the one or more protrusions (363), a stable electrical connection between the first PCB (320) and the metal sheet (370) can be provided.

[0148] According to one embodiment, a connecting member (337) may be provided near the other end of the second PCB (330) opposite to the end connected to the FPCB (350). The connecting member (337) may be made of a flexible material and may be bendable. The connecting member (337) may be connected to a connector provided on a printed circuit board (e.g., a printed circuit board (240) of FIG. 4).

[0149] According to one embodiment, in order for the circuit board assembly (310) to be placed at a predetermined angle with respect to the side frame (271), the circuit board assembly (310) in the unfolded state may have a shape as in (a). That is, the longitudinal direction (l1) of the first PCB (320) and the longitudinal direction (l2) of the second PCB (330) may not coincide with each other. Hereinafter, for convenience of explanation, the longitudinal direction (l1) of the first PCB (320) will be defined as the first longitudinal direction (l1), and the longitudinal direction (l2) of the second PCB (330) will be defined as the second longitudinal direction (l2). Here, the first longitudinal direction (l1) may be defined as the longitudinal direction of the first PCB (310), and the second longitudinal direction (l2) may be defined as the longitudinal direction of the second PCB (310).

[0150] According to one embodiment, the first longitudinal direction (l1) and the second longitudinal direction (l2) may form a predetermined angle (α). The predetermined angle (α) will be defined as a fourth angle (α). The fourth angle (α) may be an acute angle of 0° to 90°. The fourth angle (α) may be set in consideration of a predetermined angle (e.g., the first angle (θ1)) at which the circuit board assembly (310) is inclined with respect to the side frame (271).

[0151] For example, as the angle at which the circuit board assembly (310) is tilted relative to the side frame (271) increases, the fourth angle (α) will increase.

[0152] For example, as the angle at which the circuit board assembly (310) is tilted relative to the side frame (271) decreases, the fourth angle (α) will decrease.

[0153] According to one embodiment, in order for the circuit board assembly (310) to be placed at a predetermined angle relative to the side frame (271), the length (w1) of the upper side of the open end (351, hereinafter referred to as the first open end) of the FPCB (350) and the length (w2) of the lower side (353, hereinafter referred to as the second open end) of the open end may be different from each other. For example, the length (w1) of the first open end (351) may be longer than the length (w2) of the second open end (353).

[0154] According to one embodiment, the difference between the length (w1) of the first open end (351) and the length (w2) of the second open end (353) can vary in response to the first angle (θ1). Since the FPCB (350) is made of a flexible material, the first open end (351) and the second open end (353) can expand or contract within the movable range.

[0155] For example, as the first angle (θ1) increases, the difference between the length (w1) of the first open end (351) and the length (w2) of the second open end (353) may increase.

[0156] For example, as the first angle (θ1) decreases, the difference between the length (w1) of the first open end (351) and the length (w2) of the second open end (353) may decrease.

[0157] For example, as the first angle (θ1) approaches 0, i.e., as the circuit board assembly (310) is arranged parallel to the side frame (271), the length (w1) of the first open end (351) and the length (w2) of the second open end (353) may be substantially the same.

[0158] According to one embodiment, the difference between the length (w1) of the first open end (351) and the length (w2) of the second open end (353) may increase in response to the fourth angle (α). For example, as the fourth angle (α) increases, the difference between the length (w1) of the first open end (351) and the length (w2) of the second open end (353) may increase. For example, as the fourth angle (α) decreases, the difference between the length (w1) of the first open end (351) and the length (w2) of the second open end (353) may decrease.

[0159] Fig. 9 is a cross-sectional view of an antenna feed structure (300) in an exploded state according to one embodiment. That is, Fig. 9 can be understood as a cross-sectional view of the components of part B of Fig. 7 in an exploded state. For convenience of explanation, some components (e.g., the casing member (303) of Fig. 7) may be omitted.

[0160] Referring to FIG. 9, the antenna feed structure (300) may include a radiating member (305), a metal sheet (370), and a first PCB (320).

[0161] According to one embodiment, the metal sheet (370) may have a first side (371), a second side (373), a third side (372), and a fourth side (374).

[0162] According to one embodiment, the first surface (371) may be in contact with the inner surface of the casing member (303). The length of the first surface (371) may be substantially equal to or shorter than the height at which the casing member (303) extends in the z-axis direction.

[0163] According to one embodiment, the second surface (371) may be in contact with one surface of a washer (361) covering a through hole (360) provided on the back surface of the first PCB (320). The length of the second surface (371) may be substantially equal to or longer than the diameter of the washer (361).

[0164] According to one embodiment, the first side (371) and the second side (373) may form a predetermined angle. Due to the predetermined angle, the first PCB (320) may be arranged to be inclined at a predetermined angle with respect to the side frame (271a). The predetermined angle may be defined as, for example, a first angle (θ1).

[0165] According to one embodiment, as the first angle (θ1) increases, the fastening angle of the screw (380) may be inclined in the height direction (e.g., -z-axis direction) by the first angle (θ1) with respect to the bottom surface (e.g., the surface on which the front plate (220) or display (230) of the electronic device (101) is placed). Accordingly, when fastening the screw (380), physical interference between the fastening device (e.g., screw driver) and components existing around the fastening device may be minimized. Accordingly, the ease of fastening the screw (380) may be improved.

[0166] According to one embodiment, as the first angle (θ1) increases, the starting point of the feeding part (e.g., the starting point of the feeding part (301) of FIG. 7) may be positioned closer to the metal member (305). As a result, interference with the antenna radiation performance can be minimized in response to the starting point of the feeding part (301) being far from the electrical components mounted on the electronic device (101). Therefore, the radiation performance of the antenna can be improved.

[0167] According to an example, the third side (372) can be understood as the lower side of the metal sheet (370). A catch (not shown) can be provided at the point where one end of the third side (372) and one end of the second side (373) meet. The catch can be in contact with a part of the side surface of the washer (361) to support the washer (361).

[0168] In one embodiment, the angle formed by the third surface (372) and the first surface (371) may be substantially 90°.

[0169] In one embodiment, the fourth side (374) may be connected to the other end of the second side (373). The fourth side (374) may be in contact with a portion of a side surface of the washer (361) to support the washer (361). The fourth side (374) may be omitted as needed.

[0170] According to one embodiment, the metal sheet (370) may have a shape of a triangular prism whose cross-section cut along the yz plane is a right triangle. However, the present invention is not limited thereto, and the metal sheet (370) may also have a shape of a square prism whose cross-section is substantially a trapezoid. When the cross-section of the metal sheet (370) is a trapezoid, the metal sheet (370) may have a shape of a square prism whose lower side (e.g., the third side (372) of the metal sheet (370)) is longer than the upper side.

[0171] According to one embodiment, since the first side (371) of the metal sheet (370) forms a predetermined angle with the second side (373), the first PCB (320) mounted on the second side (373) of the metal sheet (370) can be arranged to be inclined at a predetermined angle with respect to the first side frame (271a).

[0172] According to one embodiment, the screw (380) may pass through a through hole (360) provided in the first PCB (320) to secure the first PCB (320) and the metal sheet (370) to the first side frame (271a). A path corresponding to the shape of the thread (383) of the screw (380) may be provided as an empty space in the metal sheet (370) or the metal member (305).

[0173] According to one embodiment, the screw (380) may include a head (381), a thread (383), and a tip (385). The screw (380) may advance in a fastening direction (d) and fasten elements constituting the antenna feed structure (300).

[0174] According to one embodiment, the fastening direction (d) of the screw (380) may be perpendicular to the surface on which the first PCB (320) is mounted on the second surface (373) of the metal sheet (370). Accordingly, the fastening angle of the screw (380) may form a predetermined angle (e.g., a first angle (θ1)) with one surface (e.g., an xy plane) of the electronic device (101). Accordingly, the ease of fastening of the screw (380) may be improved.

[0175] In one embodiment, the head (381) may have a portion removed or recessed to match the shape of the tip portion of a fastening device (e.g., a screwdriver). A portion of the head (381) may contact one surface of the metal member (305).

[0176] According to one embodiment, the thread (383) may pass through a through hole (360) provided in the first PCB (320) and be fastened to a metal sheet (370), a casing member (casing member (303) of FIG. 7), and a portion of the metal member (305).

[0177] According to one embodiment, the tip (385) may be implemented with a sharp end so as to be able to penetrate the metal sheet (370), the casing member (303), and the metal member (305).

[0178] FIG. 10 is a cross-sectional view of an electronic device (e.g., the electronic device (101) of FIG. 1) according to one embodiment. FIG. 10 may be understood as illustrating an antenna feed structure (300) in which the shape of the metal sheet (370) is applied differently from that of FIG. 7. Hereinafter, differences from FIG. 7 will be primarily described.

[0179] According to one embodiment, the casing member (303) may correspond to the casing member (303) of FIG. 7. However, the casing member (303) may be injected so that one surface thereof that contacts the metal member (305) is inclined at a predetermined angle. The predetermined angle may correspond to a first angle (e.g., the first angle (θ1) of FIG. 6). To this end, one surface of the metal member (305) that contacts the casing member (303) may be injected as an inclined surface inclined at the predetermined angle.

[0180] According to one embodiment, the metal sheet (470) may have the shape of a metal plate having a predetermined thickness. The metal sheet (470) may be attached to an inner surface opposite to one surface where the casing member (303) and the metal member (305) come into contact.

[0181] According to one embodiment, the first PCB (320) may be mounted on one side of a metal sheet (470). One side of the metal sheet (470) may be in contact with one side of a washer (361) covering a through hole (e.g., a through hole (360) of FIG. 8) of the first PCB (320).

[0182] According to one embodiment, the screw (380) can pass through a through hole (360) provided in the first PCB (320) to secure the first PCB (320), the metal sheet (470), and the casing member (303) to the metal member (305).

[0183] According to one embodiment, the surface where the first side frame (271a) and the casing member (303) come into contact is formed as an inclined plane having a predetermined angle, and a metal sheet (470) and a first PCB (320) are arranged on the inner surface of the casing member (303), and since the screw (380) is fastened in a vertical direction with the first PCB (320), the fastening angle of the screw (380) can form a predetermined angle with the bottom surface. As a result, the ease of fastening of the screw (380) can be improved. In addition, the starting point of the power supply unit (301) can be positioned adjacent to the metal member (305). As a result, interference with the antenna radiation performance can be minimized in response to the starting point of the power supply unit (301) being far from the electrical components mounted on the electronic device (101). Therefore, the radiation performance of the antenna can be improved.
