The first frequency band can include, but is not limited to, a low-band of about 300 MHz to 1,000 MHz, for example. In one or more embodiments, the connection (322) between the first point (A) and the frame (320) may be formed, for example, but not limited to, by the frame (320) contacting a connector (e.g., a C-clip connector) disposed on the first point (A). Additionally or alternatively, the electronic device (300) may include a matching circuit connected between the first point (A) and the wireless communication circuit for impedance matching.

[0096] In one or more embodiments, the frame (320) may be grounded by being connected to a second portion (352) of a printed circuit board (350). For example, the frame (320) may be grounded via a fifth point (E) and a sixth point (F) on the second portion (352). For example, the frame (320) may be electrically connected to a ground of the printed circuit board (350) via the fifth point (E) and / or the sixth point (F). For example, the ground may include at least one conductive region formed on the printed circuit board (350). The connection (324) between the fifth point (E) and the frame (320) may be formed, for example, but not limited to, by the frame (320) contacting a connector (e.g., a C-clip connector) disposed on the fifth point (E). The connection (326) between the sixth point (F) and the frame (320) may be formed, for example, by the frame (320) contacting a connector (e.g., a C-clip connector) positioned on the sixth point (F), but is not limited thereto.

[0097] In one or more embodiments, the conductive member (370) may be connected to a first portion (351) of the printed circuit board (350). For example, the conductive member (370) may be connected to a second point (B) on the first portion (351).

For example, the conductive member (370) can be electrically connected to the ground of the printed circuit board (350) through the second point (B).

[0098] In one or more embodiments, the wireless charging coil (382) may be connected to a first portion (351) of a printed circuit board (350). For example, the wireless charging coil (382) may be connected to a third point (C) on the first portion (351). For example, the wireless charging coil (382) may be connected to the third point (C) via a connecting member (386). For example, a connector (e.g., a plug) formed at an end of the connecting member (386) may be coupled to a corresponding connector (e.g., a receptacle) disposed on the third point (C), thereby connecting the wireless charging coil (382) to the printed circuit board (350). The wireless charging coil (382) may be connected to the wireless charging circuit via the first portion (351) of the printed circuit board (350).

[0099] In one or more embodiments, to prevent near field loss between the conductive member (370) and the printed circuit board (350), the conductive member (370) may be spaced apart from the printed circuit board (350). For example, the first portion (371) of the conductive member (370) may be spaced apart from the printed circuit board (350) in a second direction (D2). For example, the distance between the first portion (371) of the conductive member (370) and the printed circuit board (350) in the second direction (D2) may be about 1 mm or more, but is not limited thereto.

[0100] In one or more embodiments, the first portion (371) of the conductive member (370) and the wireless charging coil (382), which are spaced apart and facing each other, can be coupled. For example, coupling the conductive member (370) and the wireless charging coil (382) can expand the ground area of ​​the antenna. The conductive member (370) can be electromagnetically connected to the wireless charging coil (382). For example, the conductive member (370) and the wireless charging coil (382) can be capacitively coupled and / or inductively coupled. The conductive member (370) and the wireless charging coil (382) can be used as a ground for an antenna that uses at least a portion of the frame (320) as a radiator.

[0101] Additionally or alternatively, the conductive member (370) and the wireless charging coil (382) may be connected via a component disposed on the printed circuit board (350). For example, the wiring of the printed circuit board (350) connected to the conductive member (370) and the wiring of the printed circuit board (350) connected to the wireless charging coil (382) may be connected via a capacitor.

[0102] In one or more embodiments, the display (310) may be connected to a second portion (352) of a printed circuit board (350). For example, the display (310) may be connected to a fourth point (D) on the second portion (352). For example, the display (310) may be connected to the fourth point (D) of the printed circuit board (350) via a connecting member (312). For example, the display (310) may be connected to the printed circuit board (350) by a connector (e.g., a plug) formed on the connecting member (312) being coupled to a corresponding connector (e.g., a receptacle) disposed on the fourth point (D). For example, the connecting member (312) may comprise a flexible printed circuit board. In one or more embodiments, the display (310) may be grounded via the second portion (352) of the printed circuit board (350). For example, a conductive layer included in the display (310) and acting as a ground may be grounded through a fourth point (D) on the second portion (352). For example, the conductive layer of the display (310) may be electrically connected to a ground of a printed circuit board (350) through the fourth point (D). The display (310) (e.g., the conductive layer of the display panel) may be used as a ground for an antenna that uses at least a portion of the frame (320) as a radiator.

[0103] Additionally or optionally, the electronic device (300) may include a first plurality of matching circuits and a first switch circuit connected between a second point (B) of a printed circuit board (350) and ground. Any one of the first plurality of matching circuits selected through the first switch circuit may electrically connect a conductive member (370) connected to the second point (B) to the ground of the printed circuit board (350). This may enable impedance matching and / or adjustment of the resonant frequency. The antenna characteristics according to the matching circuit connected to the second point (B) will be described below with reference to FIG. 14.

[0104] Additionally or optionally, the electronic device (300) may include a second plurality of matching circuits and a second switch circuit connected between a fifth point (E) of the printed circuit board (350) and ground. Any one of the second plurality of matching circuits selected through the second switch circuit may electrically connect the frame (320) connected to the fifth point (E) to the ground of the printed circuit board (350). This may enable impedance matching and / or adjustment of the resonant frequency.

[0105] Additionally or optionally, the electronic device (300) may include a third plurality of matching circuits and a third switch circuit connected between the sixth point (F) of the printed circuit board (350) and the ground. Any one of the third plurality of matching circuits selected through the third switch circuit may electrically connect the frame (320) connected to the fifth point (E) to the ground of the printed circuit board (350). This may enable impedance matching and / or adjustment of the resonant frequency.

[0106] Wearable devices, such as electronic devices (300), are becoming increasingly compact in consideration of wearability, portability, and user preferences. Due to the limited size of wearable devices, the antenna ground, which affects various antenna characteristics such as coverage and bandwidth, may also be physically limited. In particular, antennas operating in low-frequency bands are essential for data communication, but the small size of wearable devices further limits the implementation of such antennas, as lower resonant frequencies generally require longer antennas.

[0107] FIG. 9 is a diagram illustrating current flow in an electronic device according to one or more embodiments. Referring to FIG. 9, when the frame (320) is powered through a first point (A), the display (310), the printed circuit board (350), the conductive member (370), and the wireless charging coil (382) may serve as grounds for an antenna that uses at least a portion of the frame (320) as a radiator. For example, when the frame (320) is powered through the first point (A), the current path (P) may flow to the display (310), the printed circuit board (350), the conductive member (370), and the wireless charging coil (382). The display (310) may extend the current path (P) from the printed circuit board (350). Additionally, the coupled conductive member (370) and the wireless charging coil (382) may extend the current path (P) from the printed circuit board (350). Through this, the ground of the antenna using the frame (320) can be physically and electrically expanded, thereby improving bandwidth and radiation efficiency. Furthermore, the electrical length of the antenna can be secured to form a low-band resonant frequency. The low-band may be, but is not limited to, approximately 300 MHz to 1 GHz.

[0108] In one or more embodiments, the display (310), the printed circuit board (350), the conductive member (370), and the wireless charging coil (382), together with at least a portion of the frame (320) powered through the first point (A), may form an antenna of the electronic device (300). In one or more embodiments, the display (310), the printed circuit board (350), the conductive member (370), and the wireless charging coil (382) may be used as a ground for an antenna that includes at least a portion of the frame (320) powered through the first point (A). In one or more embodiments, the display (310), the printed circuit board (350), the conductive member (370), and the wireless charging coil (382), together with the frame (320) powered through the first point (A), may be understood to operate as an antenna of the electronic device (300) to form antenna radiation.

[0109] In one or more embodiments, an antenna structure using a frame (320) may include a structure in which a display (310) used as a ground, a printed circuit board (350), a conductive member (370), and a wireless charging coil (382) are laminated substantially parallel to each other, and a structure in which the display (310) is connected to a fourth point (D) and the conductive member (370) and the wireless charging coil (382) are connected to a second point (B) and a third point (C). Such structures may lower the resonant frequency of the antenna using the metal frame (320) by increasing the capacitive loading.

[0110] In one or more embodiments, the display (310) may be grounded at a fourth point (D) of the printed circuit board (350), and the frame (320) may be powered at a first point (A). In one or more embodiments, the conductive member (370) may be grounded at a second point (B). The wireless charging coil (382) may be connected to the printed circuit board (350) at a third point (C). Each of the first point (A), the second point (B), and the third point (C) may be positioned as far apart as possible from the fourth point (D). This may lengthen the current path (P) of the antenna ground. Accordingly, the ground of the antenna using the frame (320) may be physically and electrically extended, thereby improving bandwidth and radiation efficiency.

[0111] In one or more embodiments, antenna performance may be improved as the distance (d2) between the first point (A) and the second point (B) decreases. This will be described later with reference to FIG. 13.

[0112] FIG. 10 is a diagram illustrating a radiation effective area of ​​an electronic device according to one or more embodiments. FIG. 11 is a diagram illustrating a radiation pattern of an electronic device according to one or more embodiments. Referring to FIG. 10 , in one or more embodiments, the radiation effective area may be enhanced by a conductive member (370) coupled to a wireless charging coil (382). For example, if the conductive member (370) is not included, the radiation effective area (or radiation effective volume) of the electronic device (300) may be formed as an area (A2) that includes only the display (310), the metal frame (320), and the printed circuit board (350). This may be because the current supplied to the frame (320) flows only to the printed circuit board (350) and the display (310). In contrast, since the conductive member (370) is coupled with the wireless charging coil (382) under the printed circuit board (350), the radiation effective area of ​​the electronic device (300) can be expanded to an area (A1) including the display (310), the metal frame (320), the printed circuit board (350), the conductive member (370), the wireless charging coil (382), and the cover (360) on which the wireless charging coil (382) is disposed.

[0113] Referring to FIG. 11 together with FIG. 10, the radiation pattern of an electronic device (300) having a radiation effective area (A1) including a cover (360) may include a user's body in contact with the cover (360). By utilizing the user's body in contact with the cover (360) as an antenna element, antenna performance may be improved. This may be because the user's body, which has electrical conductivity, faces parallel to the conductive member (370) and the wireless charging coil (382), and thus the user's body also acts as a ground (or radiator) for the frame (320). The effect of improving antenna performance by utilizing the body as an antenna element may increase as the resonant frequency formed by the antenna decreases. In addition, by utilizing the wireless charging coil (382) disposed on the cover (360) in contact with the user's body as the ground of the antenna, the distance between the ground and the user's body may be reduced. Accordingly, the amount of coupling between the wireless charging coil (382) and the user's body increases, thereby improving antenna performance.

[0114] Fig. 12 is a graph showing the radiation efficiency of an electronic device. Graph (1201) of Fig. 12 shows the radiation efficiency of an electronic device according to a comparative embodiment, and graph (1203) shows the radiation efficiency of an electronic device according to one or more embodiments. The electronic device according to the comparative embodiment does not include a conductive member (370). Referring to graphs (1201) and (1203) of Fig. 12, the electronic device according to one or more embodiments may have improved radiation efficiency and bandwidth in a first frequency band of about 600 MHz to about 1,400 MHz, a second frequency band of about 1,600 MHz to about 1,800 MHz, and a third frequency band of about 2,200 MHz to about 2,800 MHz, compared to the comparative embodiment. For example, the antenna performance of the first frequency band may be most significantly improved, and the antenna performance of the third frequency band including the triplet component of the first frequency band may also be improved. Accordingly, even with the limited antenna space of the electronic device (300), performance in the required frequency band can be secured. Furthermore, since antenna performance can be improved without the addition of separate circuit components, costs can be reduced and mounting space can be saved. By utilizing the saved mounting space as antenna space for other frequency bands, it can be advantageous for securing antenna performance in other frequency bands.

[0115] FIG. 13 illustrates radiation efficiency according to a distance between a first point and a second point, according to one or more embodiments. Referring to FIG. 13 together with FIG. 9, a graph (1301) illustrates radiation efficiency when a distance (d2) between a first point (A) and a second point (B) is a first distance. A graph (1303) illustrates radiation efficiency when a distance (d2) between a first point (A) and a second point (B) is a second distance that is smaller than the first distance. A graph (1305) illustrates radiation efficiency when a distance (d2) between a first point (A) and a second point (B) is a third distance that is smaller than the second distance. Referring to the graphs (1301, 1303, 1305) of FIG. 13, as the distance (d2) between the first point (A) and the second point (B) decreases, radiation efficiency may be improved. This may be because the ground extension effect of the antenna using the frame (320) is maximized as the distance (d2) between the first point (A) and the second point (B) decreases.

[0116] FIG. 14 illustrates a reflection coefficient according to a matching circuit according to one or more embodiments. Referring also to FIG. 8, graphs (1401, 1403, 1405) of FIG. 14 may represent a reflection coefficient according to a matching circuit connecting a conductive member (370) to a ground of a printed circuit board (350). Graph (1401) represents a reflection coefficient when the conductive member (370) is connected to a matching circuit having a capacitance (e.g., 100 pF). Graph (1403) represents a reflection coefficient when the conductive member (370) is connected to a matching circuit having an inductance of a first magnitude (e.g., 15 nH). Graph (1405) represents the reflection coefficient when the conductive member (370) is connected to a matching circuit having an inductance of a second magnitude (e.g., 33 nH) greater than the first magnitude. As illustrated in FIG. 14, by selectively connecting the conductive member (370) to matching circuits having different values, the resonant frequency of the antenna using the frame (320) can be adjusted.

[0117] FIG. 15 is a diagram illustrating an electronic device according to one or more embodiments. Referring to FIG. 15, a display (310) of an electronic device (1500) according to one or more embodiments (e.g., the electronic device (300) of FIG. 8) may be connected to a seventh point (G). The wireless communication circuit on a printed circuit board (350) may supply power to the display (310) through the seventh point (G). A transmission line (or conductive trace) connecting the wireless communication circuit and the seventh point (G) may be formed on and / or within the printed circuit board (350). The wireless communication circuit may transmit an RF signal of a second frequency band different from the first frequency band by supplying power to the display (310). The wireless communication circuit may receive an RF signal of the second frequency band using the display (310). The second frequency band may include, but is not limited to, a mid-band of, for example, 1,000 MHz to 2,300 MHz and / or a high-band of 2,300 MHz or more. In one or more embodiments, the connection (1512) between the display (310) and the seventh point (G) may include, but is not limited to, a C-clip connector and / or a pogo pin, for example.
