In one embodiment, the fifth portion (355) may extend from the first portion (351). The first portion (351) may be positioned between the fifth portion (355) and the sixth portion (356).

[0071] In one embodiment, the printed circuit board (250) may be configured such that at least a portion thereof is bendable. For example, the fifth portion (355), the sixth portion (356), the seventh portion (357), and / or the eighth portion (358) of the printed circuit board (250) may be formed to be flexible.

[0072] In one embodiment, the first portion (351), the second portion (352), the third portion (353), and / or the fourth portion (354) of the printed circuit board (250) may be rigidly formed. For example, various components of a ring device (e.g., the ring device (200) of FIG. 2A) may be arranged on the first portion (351), the second portion (352), the third portion (353), and the fourth portion (354).

[0073] In one embodiment, a corresponding connector may be positioned on the other end of the printed circuit board (250) opposite to the fifth portion (355), to which the connector of the battery assembly (240) of FIG. 2B is coupled. For example, the corresponding connector may be positioned on the fourth portion (354).

[0074] In one embodiment, the flexible fifth portion (355), sixth portion (356), seventh portion (357), and / or eighth portion (358) may have a curved shape. The first portion (351) and the second portion (352) may be arranged at different angles via the flexible sixth portion (356). The second portion (352) and the third portion (353) may be arranged at different angles via the flexible seventh portion (357). The third portion (353) and the fourth portion (354) may be arranged at different angles via the flexible eighth portion (358). Accordingly, the printed circuit board (250) may have an overall curved shape to correspond to the shape of the ring device (200).

[0075] In one embodiment, the printed circuit board (250) may include a conductive pattern (310) used as an antenna radiator and a matching circuit (340) connected to the conductive pattern (310) to adjust the impedance between the antenna radiator and the transmission line.

[0076] In one embodiment, a conductive pattern (310) may be formed or disposed on and / or within the fifth portion (355). The conductive pattern (310) may be formed of an electrically conductive material (e.g., a metal such as copper). In one embodiment, a matching circuit (340) may be disposed on the first portion (351). The matching circuit (340) may include, but is not limited to, lumped elements such as capacitors and inductors, and the matching circuit (340) may include various matching networks for adjusting impedance.

[0077] In one embodiment, the wireless communication circuit of the ring device (200) (e.g., the wireless communication module (192) of FIG. 1) may be electrically connected to the conductive pattern (310) via a matching circuit (340).

[0078] In one embodiment, the printed circuit board (250) may include a plurality of conductive layers extending from the first portion (351) to the eighth portion (358). For a non-limiting example, the first portion (351) of the printed circuit board (250) may include six conductive layers. For a non-limiting example, the first portion (351) may include first through sixth conductive layers positioned sequentially from the lowest layer. For a non-limiting example, the third conductive layer and the fourth conductive layer may extend beyond the first portion (351) to the fifth portion (355). For a non-limiting example, the conductive pattern (310) may be formed on the third conductive layer or the fourth conductive layer of the fifth portion (355).

[0079] In one embodiment, as described below, depending on the shape (or area) of the conductive pattern (310), the area coupled to the conductive member (e.g., the battery (442), the first member (212), or the second member (214)) facing the conductive pattern (310) may vary. Accordingly, the characteristics (e.g., resonant frequency) of the antenna using the conductive pattern (310) may vary. In FIGS. 3A and 3B , a conductive pattern (310) having a closed curve shape is illustrated as an example for controlling the amount of coupling and the antenna characteristics accordingly, but the shape of the conductive pattern (310) is not limited to the illustrated example.

[0080] FIG. 4A is an exemplary cross-sectional view of a ring device according to one embodiment. FIG. 4B is a drawing showing area (B) of FIG. 4A. FIG. 4C is a drawing corresponding to area (C) of FIG. 4A.

[0081] Referring to FIGS. 4A and 4B , a battery assembly (240) according to one embodiment may include a battery (442) (e.g., battery (189) of FIG. 1 ), an antenna (444), and a shielding member (446). The battery (442) may include, for example, a cell including an anode, a cathode, an electrolyte, and a separator for a battery reaction, and a case in which the cell is housed. At least a portion of the case may be formed of a conductive material (e.g., a metal). For example, at least a portion of a surface of the case may be formed of the conductive material. In one embodiment, the battery (442) may include a conductive portion (e.g., the case or the surface of the case) coupled with a conductive pattern (310). For example, the battery (442) may be physically separated from the conductive portion (e.g., the case or the surface of the case) that is coupled to the conductive pattern (310).

[0082] In one embodiment, the antenna (444) may include, but is not limited to, an antenna for short-range communication. For example, the antenna (444) may include a coil (e.g., a wireless charging coil) for wirelessly transmitting and receiving power to and from an external device.

[0083] In one embodiment, a shielding member (446) may be positioned between the antenna (444) and the battery (442). The shielding member (446) may be spaced from the battery (442) via a gap (g2). For example, an insulating member may be disposed in the gap (g2). The insulating member may include an insulating tape for attaching the shielding member (446) and the battery (442). The shielding member (446) may include, but is not limited to, a graphite sheet.

[0084] A ring device (200) according to one embodiment may include an insulating tape (450) disposed between a fifth portion (355) of a printed circuit board (250) and an antenna (444). The insulating tape (450) may be positioned between an end of the antenna (444) and an end of the fifth portion (355) to prevent shorting of the conductive pattern (310) of the antenna (444) and the fifth portion (355). For example, although the antenna (444) has been described as being included in the battery assembly (240), alternatively or selectively, the antenna (444) may be included in the printed circuit board (250). For example, the antenna (444) may be disposed on the fifth portion (355) of the printed circuit board (250) or on a portion extending from the fifth portion (355).

[0085] In one embodiment, the battery (442) (or the case of the battery (442)) may include a first region (461), a second region (462), and a third region (463). The first region (461), the second region (462), and the third region (463) may form a portion of the exterior of the battery (442). The first region (461) and the second region (462) may face the first side (200A) (or the second member (214)) of the ring device (200). The third region (463) may be opposite to the first region (461) and the second region (462) and may face the second side (200B) (or the first member (212)) of the ring device (200). The first region (461) may overlap with the antenna (444). For example, the first region (461) may support the antenna (444). The second region (462) may extend from the first region (461). The second region (462) may overlap the insulating tape (450) and the fifth portion (355). For example, the second region (462) may support the insulating tape (450) and the fifth portion (355).

[0086] Referring to FIG. 4C, along with FIGS. 4A and 4B, in one embodiment, a fifth portion (355) of a printed circuit board (250) can be at least partially overlapped and spaced apart from a battery assembly (240). A conductive pattern (310) of the fifth portion (355) can face and be spaced apart from a battery (442) of the battery assembly (240). For example, the conductive pattern (310) of the fifth portion (355) can face and be spaced apart from the conductive portion (e.g., the case) of the battery (442). For example, the conductive pattern (310) can at least partially overlap the battery (442). For example, with respect to a direction perpendicular to the first surface (200A), the conductive pattern (310) can at least partially overlap the battery (442).

[0087] In one embodiment, the conductive pattern (310) may include a first section (411) that overlaps the battery (442) in a direction perpendicular to the first surface (200A) and a second section (412) that extends away from the first section (411) in a direction away from the battery (442). The first section (411) may be located between the battery (442) and the first surface (200A). For example, the first section (411) may be supported by the second region (462) of the battery (442). For example, but not limited to, the second section (412) may include a step section. For example, the second section (412) may include a section that is closer to the second surface (200B) than the first section (411). Through the above-mentioned step section, a portion of the second section (412), such as the first section (411) of the conductive pattern (310), may extend adjacent to the first surface (200A). In one embodiment, the second section (412) may be electrically connected to the wireless communication circuit.

[0088] In one embodiment, the first section (411) may be separated from the battery (442) via a gap (g1). For example, an insulating member may be disposed in the gap (g1). The insulating member may include an insulating tape for attaching the fifth portion (355) of the printed circuit board (250) and the battery (442). The gap (g1) may be, for example, about 0.1 mm or more and 0.3 mm or less, but is not limited thereto. The gap (g1) may be, for example, about 0.2 mm or more.

[0089] In one embodiment, the conductive portions of the conductive pattern (310) and the battery (442), which are facing each other and spaced apart from each other, can be coupled. The wireless communication circuit can transmit or receive an RF signal using the conductive pattern (310) and the battery (442) coupled to the conductive pattern (310).

[0090] FIG. 5a and FIG. 5b are drawings showing the antenna structure of a ring device according to one embodiment.

[0091] Referring to FIG. 5A, a conductive pattern (310) and a battery (442) may be coupled at a region (c1). The wireless communication circuit may supply power to the conductive pattern (310). Electrical energy of the conductive pattern (310) may be transmitted to the battery (442) through the coupled region (c1). The conductive pattern (310) and the battery (442) coupled to the conductive pattern (310) may form an antenna radiator. Through the battery (442) coupled to the conductive pattern (310), the length of the antenna radiator may be increased, as illustrated by arrow (a1). For example, the radiation area of ​​the antenna radiator may be expanded. Accordingly, the radiation performance of an antenna using the conductive pattern (310) and the battery (442) may be improved.

[0092] Referring to FIG. 5B, the conductive pattern (310) and the battery (442) may have a first length (l1). The first length (l1) may be, for example, approximately 1 / 4 of the wavelength (λ) of the communication frequency to be implemented through the antenna using the conductive pattern (310) and the battery (442). The remaining portion of the printed circuit board (250), excluding the conductive pattern (310), may have a second length (l2). For example, but not limited to, the second length (l2) may be substantially the same as the first length (l1). For example, the second length (l2) may be approximately 1 / 4 of the wavelength (λ) of the communication frequency to be implemented. This may be equivalent to a dipole antenna in which the lengths of the arms are each implemented as λ / 4. Through this, it is possible to reduce or prevent degradation of antenna performance due to insufficient ground area of ​​the printed circuit board (250). For example, even if there is insufficient mounting space to secure the ground area of ​​the ring device (200), the deterioration of antenna performance can be reduced or prevented.

[0093] Fig. 6 is a drawing showing a ring device according to a comparative embodiment. Referring to Fig. 6, a ring device (602) according to a comparative embodiment includes a metal ring (612) forming an exterior (e.g., a first member (212)), a printed circuit board (650), an antenna pattern (610) formed on the printed circuit board (650), and a battery (642).

[0094] The antenna pattern (610) of the ring device (602) of the comparative embodiment may be formed to be spaced apart from the battery (642) to reduce the impact on the performance of the battery (642). Due to the design constraints resulting from this and the small volume of the ring device (602) itself, the antenna pattern (610) of the ring device (602) according to the comparative embodiment may have difficulty meeting the length required to form a resonant frequency. In addition, the radiation performance of the antenna pattern (610) may be degraded by the metal ring (612).

[0095] In contrast, according to one embodiment, a ring device (e.g., a ring device (200) of FIG. 4A) can easily secure the length and performance of an antenna for forming a resonant frequency by using a conductive pattern (310) and a battery (442) coupled to the conductive pattern (310) as an antenna radiator.

[0096] Fig. 7 is a drawing showing a ring device according to a comparative embodiment. Referring to Fig. 7, a ring device (702) according to a comparative embodiment includes a metal ring (712) forming an exterior (e.g., a first member (212)), a printed circuit board (750), a chip antenna (710) formed on the printed circuit board (750), and a battery (742).

[0097] The chip antenna (710) of the ring device (702) of the comparative embodiment may be formed to avoid the battery (742) in order to reduce the impact on the performance of the chip antenna (710). Accordingly, the chip antenna (710) of the ring device (702) according to the comparative embodiment may have difficulty meeting the length for forming a resonant frequency. In addition, in order to prevent the radiation performance of the chip antenna (710) from being degraded by the metal ring (712), the metal ring (712) may include a non-conductive portion (714) aligned with the chip antenna (710). Such a non-conductive portion (714) may restrict the external design of the ring device (702) and may entail unnecessary processes for manufacturing the non-conductive portion (714).

[0098] In contrast, according to one embodiment, a ring device (e.g., a ring device (200) of FIG. 4A) can easily secure the length and performance of the antenna for forming a resonant frequency by using a conductive pattern (310) and a battery (442) coupled to the conductive pattern (310) as an antenna radiator. In addition, unnecessary parts, such as a non-conductive portion (714), may not be required in the first member (212) for the radiation performance of the antenna radiator. Accordingly, design freedom can be improved, and unnecessary process costs can be reduced.

[0099] FIG. 8 is a graph showing the radiation efficiency of a ring device according to an embodiment and ring devices according to a comparative embodiment. In FIG. 8, graph (800) shows the radiation efficiency of a ring device (200) according to an embodiment. Graph (806) shows the radiation efficiency of a ring device (602) according to a comparative embodiment. Graph (807) shows the radiation efficiency of a ring device (702) according to a comparative embodiment.

[0100] Referring to FIG. 8, the radiation efficiency of graph (800) may be higher than the radiation efficiency of graphs (806, 807) in a frequency band of 1,000 MHz to about 4,000 MHz. For example, the radiation efficiency of graph (800) may be higher than the radiation efficiency of graphs (806, 807) in a Bluetooth spectrum band of 2,400 MHz to 2,483.5 MHz.

[0101] Table 1 below shows the transmit power and communication distance of a ring device (200) according to one embodiment and ring devices (602, 702) according to a comparative embodiment.

[0102] Ring device (200) according to the embodiment of the day of distinction Ring device (602) according to the comparative embodiment Ring device (702) according to the comparative embodiment Transmission power -4 dBm -1 dBm -1 dBm Communication distance 40 m 34 m 25 m

[0103] Referring to Table 1, the ring device (200) according to one embodiment can have reduced transmission power and increased communication distance compared to the ring devices (602, 702) according to comparative embodiments. As the transmission power is reduced, the current consumption of the battery can be reduced.

[0104] FIG. 9 is a diagram illustrating an electric field distribution of a ring device according to an embodiment. FIG. 9 may be an electric field distribution of a ring device (200) when an antenna radiator using a conductive pattern (310) and a battery (442) of FIG. 5b is in operation. Referring to FIG. 9 along with FIG. 5b, radiant energy may be concentrated at an end portion (d) of the battery (442). This may be because the conductive portion of the battery (442) coupled to the conductive pattern (310) operates as an antenna radiator.

[0105] FIG. 10A illustrates a state in which a ring device according to an embodiment is worn on a human phantom. FIG. 10B illustrates a radiation pattern of a ring device according to an embodiment. FIG. 10B shows the radiation pattern of the ring device when worn on the human phantom of FIG. 10A. For example, the z direction of FIG. 10B may be a direction toward the tip of the finger on which the ring device is worn. Referring to FIGS. 10A and 10B, the radiation pattern of the ring device according to an embodiment may have the greatest radiation intensity toward the front direction of the finger.

[0106] FIG. 11A is an exemplary cross-sectional view of a ring device according to one embodiment. FIGS. 11B and 11C are drawings showing area (D) of FIG. 11A.

[0107] Referring to FIGS. 11A, 11B, and 11C, the conductive pattern (310) of the ring device (1100) (e.g., the ring device (200) of FIG. 4A) may be positioned between the battery (442) and the first member (212), unlike the illustration of FIG. 4A. For example, the first section (411) of the conductive pattern (310) may be positioned between the battery (442) and the second face (200B) of the ring device (1100) (or the first member (212)). The first section (411) may overlap the battery (442). For example, the first section (411) may overlap the battery (442) with respect to the direction perpendicular to the second face (200B). The first section (411) can cover at least a portion of the third region (463) of the battery (442). For example, the first section (411) can be supported by the third region (463) of the battery (442). For a non-limiting example, the first section (411) can be positioned within a recess (R) formed in the third region (463) of the battery (442). An insulating member can be disposed between the first section (411) and the battery (442). The insulating member can include, for example, an insulating tape for attaching the first section (411) to the battery (442). In one embodiment, the fifth portion (355) (or the conductive pattern (310)) of the printed circuit board (250) can extend along the second side (200B) of the first member (212). For example, an insulating material (e.g., resin) may be formed between the fifth portion (355) and the first member (212). As a non-limiting example, an insulating material (e.g., insulating tape) may be placed between the fifth portion (355) and the first member (212).

[0108] In one embodiment, the first section (411) may be supported by the first member (212). The first section (411) of the conductive pattern (310) may be covered by the first member (212). For example, the first section (411) of the conductive pattern (310) may overlap the first member (212). For example, the first section (411) may overlap the first member (212) with respect to the direction perpendicular to the second surface (200B).

[0109] In one embodiment, the conductive pattern (310) can be coupled with the battery (442) and the first member (212). In one embodiment, the first section (411) can be spaced apart from and facing the battery (442) so that the conductive portion of the conductive pattern (310) and the battery (442) can be coupled. Furthermore, the first section (411) can be spaced apart from and facing the first member (212) so that the conductive pattern (310) and the first member (212) can be coupled. In one embodiment, the first member (212) can be at least partially formed of a conductive material. For example, the region (or portion) of the first member (212) that faces the first section (411) can be formed of a conductive material. For non-limiting example, the entire first member (212) can be formed of a conductive material. For example, the length of the first section (411) may be about 2 mm or more and 8 mm or less. For example, the length of the first section (411) may be about 5 mm. For example, the length of the second section (412) may be about 2 mm or more and 8 mm or less. For example, the length of the second section (412) may be about 5 mm. The first area where the first section (411) faces the battery (442) may be substantially the same as the second area where the first section (411) faces the first member (212), but is not limited thereto. For example, the first area and the second area may be different from each other. For example, the first area may be smaller than the second area. The first area and the second area may vary depending on the communication frequency of the antenna.

[0110] In one embodiment, the wireless communication circuit can transmit or receive an RF signal using a conductive pattern (310) and a battery (442) coupled to the conductive pattern (310) and a first member (212).

[0111] Fig. 12 is a drawing showing an antenna structure of a ring device according to one embodiment.

[0112] Referring to FIG. 12, the conductive pattern (310) can be coupled with the battery (442) and the first member (212) in the region (c2). The wireless communication circuit can supply power to the conductive pattern (310). The electrical energy of the conductive pattern (310) can be transmitted to the battery (442) and the first member (212) through the coupled region (c2). The conductive pattern (310), the battery (442), and the first member (212), which are coupled to each other, can form an antenna radiator. Through the coupling of the conductive pattern (310) and the battery (442), the length of the antenna radiator can be increased, as illustrated by the arrow (a1). In addition, through the coupling of the conductive pattern (310) and the first member (212), the length of the antenna radiator can be increased, as illustrated by the arrows (a2, a3). For example, the radiation area of ​​the antenna radiator can be expanded. Accordingly, the radiation performance of the antenna using the conductive pattern (310), the battery (442), and the first member (212) can be improved.

[0113] Additionally, the antenna (444) may include an extension portion (1245), unlike the illustration in FIG. 5A. The extension portion (1245) may be positioned in a free space formed when the position of the conductive pattern (310) in FIG. 5A is changed to the opposite side of the battery (442). For example, the extension portion (1245) may overlap the battery (442) and the conductive pattern (310) (e.g., the first section (411) in FIG. 11C). The battery (442) may be partially positioned between the extension portion (1245) and the conductive pattern (310). As the antenna (444) further includes the extension portion (1245), the transmission and reception performance (e.g., wireless charging performance) of the antenna (444) may be improved.

[0114] FIG. 13 is a graph showing the radiation efficiency of ring devices according to one embodiment. In FIG. 13, graph (800) shows the radiation efficiency of ring device (200) according to one embodiment. Graph (1300) shows the radiation efficiency of ring device (1100) according to one embodiment.

[0115] Referring to FIG. 13, the radiation efficiency of the graph (1300) may be higher than that of the graph (800) in the frequency band of 1,500 MHz to 4,500 MHz. This may be because, in the case of the ring device (1100), unlike the ring device (200), the first member (212) is additionally used as an antenna radiator.

[0116] FIG. 14 is a diagram illustrating a ring device according to an embodiment. Referring to FIG. 14, a second member (214) of a ring device (1400) according to an embodiment (e.g., the ring device (200) of FIG. 5A) may include a conductive portion (1414). For example, the conductive portion (1414) may be formed of a conductive material (e.g., a metal). The conductive portion (1414) may at least partially form a first surface (200A) of the ring device (1400).

[0117] In one embodiment, the conductive pattern (310) may be disposed between the battery (442) and the conductive portion (1414). The conductive pattern (310) may be coupled to the battery (442) and the conductive portion (1414) in the region (c3). The conductive pattern (310) may be spaced apart from and facing the battery (442) for the coupling. The conductive pattern (310) may be spaced apart from and facing the conductive portion (1414) of the second member (214) for the coupling.

[0118] In one embodiment, the wireless communication circuit can transmit or receive an RF signal using a conductive pattern (310) and a battery (442) and a conductive portion (1414) coupled to the conductive pattern (310). By coupling the battery (442) and the conductive portion (1414) to the conductive pattern (310), the radiation area of ​​the antenna radiator can be expanded, and the radiation performance can be improved.

[0119] FIGS. 15A, 15B, and 15C illustrate various examples of conductive patterns according to one embodiment. In FIGS. 15A, 15B, and 15C, various examples of conductive patterns (310) are illustrated.

[0120] Referring to FIG. 15A, the conductive pattern (1501-1) may include a first pattern (1511). The first pattern (1511) may extend outward from the first portion (351) of the printed circuit board (250) along the third side (200C). For a non-limiting example, the first pattern (1511) may extend parallel to the third side (200C). For a non-limiting example, the first pattern (1511) may extend substantially straight. The first pattern (1511) may be closer to the third side (200C) than to the fourth side (200D). The conductive pattern (1501-1) may form an inverted F antenna (IFA).

[0121] Referring to FIG. 15B, the conductive pattern (1501-2) may have a substantially rectangular shape. For example, the conductive pattern (1501-2) may have a rectangular ring shape with an opening (1515) formed therein. For example, the conductive pattern (1501-2) may further include a second pattern (1512), a third pattern (1513), and a fourth pattern (1514) compared to the conductive pattern (1501-1).

[0122] The second pattern (1512) may extend outward from the first portion (351) of the printed circuit board (250) along the fourth surface (200D). The second pattern (1512) may be closer to the fourth surface (200D) than to the third surface (200C). The second pattern (1512) may be spaced apart from the first pattern (1511). For example, but not limited to, the second pattern (1512) may be substantially parallel to the first pattern (1511). For example, as illustrated in FIG. 3B, the conductive pattern (1510-2) may have a trapezoidal shape in which the distance between the first pattern (1511) and the second pattern (1512) increases as it moves away from the first portion (351).

[0123] The third pattern (1513) may extend from the first end of the first pattern (1511) to the first end of the second pattern (1512). The fourth pattern (1514) may extend from the second end of the first pattern (1511) to the second end of the second pattern (1512). For example, but not limited to, the fourth pattern (1514) may be substantially parallel to the third pattern (1513).

[0124] Referring to FIG. 15c, the conductive pattern (1510-3) may include a square patch. The conductive pattern (1510-3) may be a pattern in which an opening (1515) within the conductive pattern (1510-2) of FIG. 15b is filled with a conductive material.

[0125] FIG. 16 is a graph showing radiation efficiency according to a conductive pattern according to an embodiment. In FIG. 16, the radiation efficiency of the conductive patterns (1510-1, 1510-2, 1510-3) of FIGS. 15A, 15B, and 15C are illustrated. For example, graph (1600) may be the radiation efficiency of the conductive pattern (1510-2) when it is not worn on the human body. Graph (1602) may be the radiation efficiency of the conductive pattern (1510-2) when it is worn on the human body. Graph (1604) may be the radiation efficiency of the conductive pattern (1510-3) when it is worn on the human body. Graph (1606) may be the radiation efficiency of the conductive pattern (1510-1) when it is worn on the human body.

[0126] As the area of ​​the conductive pattern increases, the influence due to the human body may increase, while the coupled area may also increase. Referring to graph (1600), in the frequency band of 2,400 MHz to 2,483.5 MHz, the radiation efficiency of the conductive pattern (1510-2) in the FREE state, which is not worn on the human body, may be the highest. Referring to graph (1602), even when worn on the human body, the radiation efficiency of the conductive pattern (1510-2) may be substantially the same as the radiation efficiency in the FREE state (graph (1600)). On the other hand, referring to graphs (1604, 1606), the radiation efficiency of the conductive pattern (1510-3) and the conductive pattern (1510-1) may be lower than the radiation efficiency of the conductive pattern (1510-2) (graphs (1600, 1602)). This may be due to insufficient coupling due to too small an area of ​​the conductive pattern, or increased influence on the human body due to too large an area of ​​the conductive pattern.
