For the IFA type antenna, each component of the antenna radiator (360) is described through FIG. 5.

The feeding portion (510) of the antenna radiator (360) may be electrically connected to a feeding unit (501). The electronic device (100) may be configured to radiate an RF signal to the outside by feeding the RF signal from the feeding unit (501) (e.g., the feeding unit (401) of FIG. 4, or a feeding line connected to a wireless communication circuit on a PCB (340)) to the antenna radiator (360). In addition, the electronic device (100) may be configured to transmit a wireless signal received through the antenna radiator (360) to the feeder (501). According to embodiments of the present disclosure, the ground portion (520) of the antenna radiator (360) may be electrically connected to the ground (502) (e.g., the ground (402) of FIG. 4 , or the ground layer of the PCB (340)). In order to sufficiently secure the radiation performance of the antenna radiator (360) within the limited space of the electronic device (100), an IFA type antenna may be used. For the IFA type antenna, the ground portion (520) may be electrically connected to the ground (502) (e.g., an area connected to the ground layer of the PCB (340)) through a connecting member (e.g., a C-clip, a conductive pattern). The ground portion (520) may be referred to as a ground point of the IFA type antenna. For the above IFA type antenna, the feeding portion (510) of the antenna radiator (360) may be electrically connected to the feeding portion (501) of the electronic device (100) (e.g., a feeding line connected to a wireless communication circuit on a PCB (340)). The above-mentioned area may be referred to as a feeding point of the IFA type antenna.For the IFA type antenna, the antenna radiator (360) may include an open area (533). For example, the open area (533) may refer to an area including an end point on the side opposite to the side where a ground point or a feed point is formed among the antenna radiators (360). The end point may be referred to as an open point of the IFA type antenna. For example, a separate feed point or a ground point may not be formed within the open area (533). At least a portion of the antenna radiator (360) may have an area in a plane (e.g., an xy plane). The antenna radiator (360) may correspond to a planar inverted F antenna (PIFA) type antenna as an example of an IFA type antenna. In one embodiment, the antenna radiator (360) may be implemented as a flexible printed circuit board (FPCB).

[0054] According to one embodiment, the antenna radiator (360) may include a feed portion (510), a ground portion (520), and a conductive portion (530). The feed portion (510) may correspond to a first end of the antenna radiator (360). The feed portion (510) may be electrically connected to a wireless communication circuit of a PCB (340). The wireless communication circuit may be configured to transmit a signal in a frequency band (e.g., a low frequency band, about 600 MHz to 1.2 GHz) for transmission through the antenna radiator (360). The feed portion (510) may be formed to extend from the conductive portion (530). The feed portion (510) may be electrically connected to a component of the PCB (340) (e.g., a wireless communication circuit on a second surface). For this purpose, the power supply portion (510) may be disposed between the non-conductive support portion (350) and the second surface of the PCB (340). The ground portion (520) may be electrically connected to the ground of the electronic device (100). The ground portion (520) may correspond to the second end of the antenna radiator (360). The ground may correspond to at least one of the ground of the PCB (340), the frame (106), the bracket (330), and / or the metal substrate of the display (120). For example, the ground portion (530) may be electrically connected to the ground of the PCB (340), and the ground of the PCB (340) may be connected to a portion of the frame (106). The ground portion (520) may be formed to extend from the conductive portion (530). The ground portion (520) may be electrically connected to a component of the PCB (340) (e.g., a wireless communication circuit on the second surface). For this purpose, the ground portion (520) may be positioned between the non-conductive support portion (350) and the second surface of the PCB (340). The conductive portion (530) may refer to a portion formed between the power supply portion (510) and the ground portion (520).For example, a part of the conductive portion (530) may be placed behind (e.g., in the (-) z-axis direction) the non-conductive support portion (350). To this end, a part of the antenna radiator (360) may pass through at least one hole (not shown) of the non-conductive support portion (350). For example, at least a part of the conductive portion (530) or the feed portion (510) may pass through a hole (not shown) of the non-conductive support portion (350). For example, at least a part of the conductive portion (530) or the ground portion (520) may pass through a hole (not shown) of the non-conductive support portion (350).

[0055] In order to function as an IFA type antenna, the antenna radiator (360) may be required to have sufficient length. For resonance and radiation efficiency, the wavelength of the transmitted signal may be When the IFA type antenna is said to be, the length from the ground point (the end connected to the ground in the IFA antenna) to the open point (the open end in the IFA antenna) is / 4 (hereinafter, IFA antenna length or PIFA antenna length) may be required. For example, in order to transmit a signal with a frequency of 800 MHz, an IFA antenna length of about 93.75 mm or more may be required. In order to secure the corresponding antenna length within the limited space of the electronic device (100), the conductive portion (530) of the antenna radiator (360) may be arranged such that one area (e.g., open area (533)) of the conductive portion (530) is adjacent to one side (e.g., the first side (411) of FIG. 4) of the electronic device (100) adjacent to the feed portion (510) and the ground portion (520) and the opposite side (e.g., the second side (412) of FIG. 4). For example, the feed portion (510) and the ground portion (520) may be adjacent to the first side (411) of the electronic device (100). A portion of the conductive portion (530) may be disposed on a second side (412) of the electronic device (100) opposite to the first side of the electronic device (100). For example, the first side (411) may face upward (e.g., in the (-) x-axis direction) and the second side (412) may face downward (e.g., in the (+) x-axis direction) with respect to a plane (e.g., an xy plane). The feeding portion (510) may correspond to a feeding point of an IFA type antenna. The ground portion (520) may correspond to a grounding point of an IFA type antenna. An open area (533) of the conductive portion (530) may correspond to an open point of an IFA antenna. When looking at the second side (e.g., the second side (442) of FIG. 4) of the PCB (340), the antenna radiator (360) may be arranged such that the feed portion (510) and the ground portion (520) are adjacent to the first side (411) and at least a portion of the conductive portion (530) is adjacent to the second side (412) opposite to the first side (411). The feed portion (510) and the ground portion (520) may be connected to the second side (442) of the PCB (340).Accordingly, the power supply portion (510) and the ground portion (520) can be arranged adjacent to the first side (411) of the electronic device (100). The distance from the ground point (e.g., the ground portion (520)) to the open point is approx. / 4 or more is required, an area of ​​the conductive portion (530) corresponding to the open point may be arranged adjacent to the second side (412) of the electronic device (100). As an example, the shape of the conductive portion (530) may correspond to a 'U' shape. At least a portion of the antenna radiator (360) may include a 'U' shape.

[0056] Fig. 6 illustrates an example of a connection portion between an antenna radiator (e.g., antenna radiator (360)) and a printed circuit board (PCB) (e.g., PCB (340)). Fig. 6 describes a connection structure between the antenna radiator (360) and the PCB (340). The same reference numbers may indicate the same description.

[0057] Referring to FIG. 6, the electronic device (100) may include a first connection portion (610) and a second connection portion (620). Each of the first connection portion (610) and the second connection portion (620) may be referred to as a connection member, a conductive member, a contact member, a contact portion, a contact, a feeding contact, an antenna contact, and / or equivalent technical / structural terms in addition to the connection portion. For example, each of the first connection portion (610) and the second connection portion (620) may include a C-clip. The first connection portion (610) may be used to connect the PCB (340) and the feeding portion (510) of the antenna radiator (360). For example, the first connection portion (610) may electrically connect a feeding line from a wireless communication circuit of the PCB (340) and the feeding portion (510). The second connecting portion (620) can be used to connect the PCB (340) and the ground portion (520) of the antenna radiator (360). For example, the second connecting portion (620) can electrically connect the ground layer of the PCB (340) and the ground portion (520).

[0058] According to one embodiment, the first connection portion (610) may be disposed on a second surface (e.g., the second surface (442) of FIG. 4) of the PCB (340) (e.g., the surface facing the (-) z-axis). The first connection portion (610) may be in contact with the feeding portion (510) of the antenna radiator (360). RF signals from the feeding portion (e.g., the feeding portion (501) of FIG. 5) disposed on the PCB (340) may be fed to the conductive portion (530) through the first connection portion (610). The second connection portion (620) may be disposed on a second surface (442) of the PCB (340) (e.g., the surface facing the (-) z-axis). The second connection portion (620) may be in contact with the ground portion (520) of the antenna radiator (360). The antenna radiator (360) can function as a radiator of an IFA type antenna by connecting the power supply portion (510) to the power supply portion (501) through the first connection portion (610) and connecting the ground portion (520) to the ground (502) through the second connection portion (620).

[0059] As illustrated in FIG. 6, a distance between the conductive portion (530) and the second side (442) of the PCB (340) in one axis (e.g., the z-axis) may be greater than a distance between the feeding portion (510) and the conductive portion (520) from the second side (442) of the PCB (340). For example, at least a portion of the conductive portion (530) may be disposed on a portion of a non-conductive support portion (e.g., the non-conductive support portion (350)). The portion may have a surface facing the (-) z-axis. The feeding portion (510) may extend from the conductive portion (530). For example, the conductive portion (530) may be connected to the feeding portion (510) by passing through a hole (not shown) in the non-conductive support portion (350). The ground portion (520) may extend from the conductive portion (530). For example, the conductive portion (530) can be connected to the ground portion (520) through a hole (not shown) of the non-conductive support portion (350).

[0060] Fig. 7a shows an example of a connection structure between an antenna radiator (e.g., antenna radiator (360)) and a PCB (e.g., PCB (340)). The same reference numbers may indicate the same description.

[0061] Referring to FIG. 7A, the electronic device (100) may include a first connection portion (610) and a second connection portion (620). For example, the first connection portion (610) may include a C-clip. The second connection portion (620) may include a C-clip. The first connection portion (610) may be used to connect the PCB (340) and the feeding portion (510) of the antenna radiator (360). The second connection portion (620) may be used to connect the PCB (340) and the ground portion (520) of the antenna radiator (360). Through the first connection portion (610) and the second connection portion (620), the antenna radiator (360) and the PCB (340) may be connected in a loop shape.

[0062] According to one embodiment, the antenna radiator (360) may be disposed on a rear surface area of ​​the electronic device (100) (e.g., an area facing the second surface (442) of the PCB (340). For target performance, the antenna radiator (360) may have a loop shape in which one end is connected to ground and the other end is open, for the operating characteristics of a PIFA type antenna. In order to function as a PIFA type antenna, the other end of the antenna radiator (360) (e.g., the ground portion (520)) may be shorted to ground. In order to function as a PIFA type antenna, the antenna radiator (360) may have a feed point (e.g., the feed portion (510)) that is separated from the shorting point. The conductive portion (530) may refer to a portion formed between the feed portion (510) and the ground portion (520). As a non-limiting example, the conductive portion (530) may be formed integrally with the feed portion (510) and the ground portion (520). A portion of the conductive portion (530) may be adjacent to a side of the electronic device (100) opposite to the side to which the feed portion (510) and the ground portion (520) are adjacent, in order to secure a length for resonance in an IFA type antenna. For example, the feed portion (510) and the ground portion (520) may be adjacent to a first side of the electronic device (100) (e.g., a portion facing the (-) x-axis, the first side (411) of FIG. 4). A portion of the conductive portion (530) may be disposed on a second side of the electronic device (100) opposite to the first side of the electronic device (100) (e.g., a portion facing the (+) x-axis, the second side (412) of FIG. 4). In one embodiment, when looking at the second side (442) of the PCB (340), the shape of the conductive portion (530) may correspond to a 'U' shape. In one embodiment, when looking at the second side (442) of the PCB (340), at least a portion of the antenna radiator (360) may have a 'U' shape.For example, the antenna radiator (360) may be formed in a loop shape with an open end.

[0063] The antenna radiator (360) and the PCB (340) can be connected through a first connection portion (610) and a second connection portion (620). The conductive portion formed from the power supply portion (510) in contact with the first connection portion (610) to the ground portion (520) in contact with the second connection portion (620) through the conductive portion (530) can have a 'U' shape. The antenna radiator (360) can have a 'U' shape in which the side (e.g., the first side (411)) connected to the PCB (340) is open. By connecting one end of the antenna radiator (360) to the ground (i.e., by being short-circuited), the antenna radiator (360) can function as an IFA type antenna. Since at least a portion of the antenna radiator (360) has an area in one plane (e.g., xy plane), the antenna radiator (360) may correspond to a planar inverted F antenna (PIFA) type antenna. As the PIFA type antenna is implemented through shorting one end of the antenna radiator (360) within a limited area of ​​the electronic device (100), the required radiation performance can be secured. The performance according to the PIFA type antenna is described in detail through FIG. 7b.

[0064] In FIG. 7A, a C-clip is exemplified as a connecting member for electrical connection between the antenna radiator (360) and the PCB (340), but embodiments of the present disclosure are not limited thereto. For example, a separate conductive pattern and / or conductive BI may be used instead of the C-clip as the first connecting portion (610) or the second connecting portion (620).

[0065] Fig. 7b illustrates an example of performance according to the ground portion of an antenna radiator (e.g., antenna radiator (360)). Like reference numerals may indicate like descriptions. Fig. 7b illustrates a performance comparison between a monopole type antenna and a PIFA type antenna.

[0066] Referring to FIG. 7B, a graph (700) may represent total efficiency (or may be referred to as antenna efficiency) with respect to frequency. The total efficiency may represent the ratio of radiated power to the total power consumed by the antenna. The horizontal axis of the graph (700) represents frequency (unit: GHz (gigahertz)) and the vertical axis of the graph (700) represents total efficiency (unit: dB (decibel)). A line (751) represents the radiation performance of a conductive member when one end of the conductive member is not connected to the ground of the PCB (340). If one end of the conductive member is not connected to the ground, the conductive member can be used as a radiator of a monopole type antenna. For example, the line (751) may represent the total efficiency with respect to frequency when the end corresponding to the ground portion (520) of the antenna radiator (360) has an open structure. Line (752) represents the radiation performance of a conductive member (e.g., antenna radiator (360)) when one end (e.g., ground portion (520)) of the conductive member is connected to the ground of the PCB (340). As one end of the conductive member is connected to the ground of the PCB (340), the conductive member can be used as a radiator of a PIFA type antenna. For example, line (752) can represent the overall efficiency for frequency when the end corresponding to the ground portion (520) of the antenna radiator (360) has a structure in which it is shorted to the ground. As an example, the electronic device (100) can transmit a signal in Band 14 (FDD, UL: 788-798 MHz, DL: 758-768 MHz). Referring to graph (700), it can be confirmed that line (752) exhibits higher overall efficiency than line (751) in the corresponding frequency band. To obtain high overall efficiency in the frequency band, one end (e.g., ground portion (520)) of a conductive member (e.g., antenna radiator (360)) may be short-circuited.The required efficiency can be secured as the above conductive member functions as a PIFA type antenna.

[0067] Fig. 7c illustrates an example of a switching circuit for a ground portion (e.g., ground portion (520)). Like reference numerals may indicate like descriptions.

[0068] Referring to FIG. 7C, the electronic device (100) may include an antenna radiator (360). A wireless signal (720) may be provided to the antenna radiator (360) from a source (710) (e.g., a wireless communication circuit on a PCB (340)). The wireless signal (720) may be provided to a feeding portion (510) of the antenna radiator (360). A ground portion (520) of the antenna radiator (360) may be connected to a ground (750) (e.g., a metal portion of the frame (106), the display (120), or the bracket (330)) through a ground path (740) (e.g., a via or a ground line). Through this connection structure, the antenna radiator (360) may function as a radiator of a PIFA type antenna. For wideband in low frequency band, the antenna radiator (360) may be electrically connected to a switching circuit (730). A ground portion (520) of the antenna radiator (360) may be connected to a ground of a PCB (340) via a connecting member (e.g., a second connecting portion (620)). The ground of the PCB (340) may be connected to a ground (750) via a ground path (740). The switching circuit (730) may be electrically connected to the ground path (740). For example, the switching circuit (730) may be disposed on the PCB (340). According to one embodiment, the switching circuit (730) may include a plurality of elements (e.g., a first element (731), a second element (732), a third element (733), and / or a fourth element (734)). Instead of the ground portion (520) being directly connected to the ground (750), the ground portion (520) can be connected to the ground via a switching circuit (730) through a component, thereby performing impedance matching. The switching circuit (730) can electrically connect one of the plurality of components to the ground portion (520). Depending on the operation of the switching circuit (730), the impedance matching at the ground portion (520) can vary.Depending on the operation of the switching circuit (730), the time constant value for resonance may change. The electronic device (100) may shift resonance by changing the time constant value.

[0069] Fig. 7d illustrates an example of time constant control using a switching circuit (e.g., switching circuit (730)) for a ground portion (e.g., ground portion (520)). Like reference numerals may represent like descriptions.

[0070] Referring to FIG. 7D, a graph (760) may represent total efficiency with respect to frequency. The horizontal axis of the graph (760) represents frequency (unit: GHz) and the vertical axis of the graph (760) represents total efficiency (unit: dB). The electronic device (100) may include an antenna radiator (360). The antenna radiator (360) may function as a radiator of a PIFA type antenna. To adjust the time constant of the antenna radiator (360) at the ground, the electronic device (100) may include a switching circuit (730). Depending on the operation of the switching circuit (730), an inductor and / or capacitance in a ground path (e.g., ground path (740)) may change. As the inductor and / or capacitance change, a time constant value for resonance of the antenna radiator (360) may change. For example, referring to graph (760), the resonance can shift (770) depending on which element is connected to the ground path (740) in the switching circuit (730).

[0071] FIGS. 8A, 8B, and 8C are drawings for explaining the radiation pattern of an antenna radiator (e.g., antenna radiator (360)). The same reference numbers may indicate the same description.

[0072] Referring to FIG. 8A, an example (800) illustrates a PCB (340) and an antenna radiator (360) when viewed from a second side of the PCB (340) of the electronic device (100) (e.g., a side of the PCB (340) facing the (-) z-axis, the second side (442) of FIG. 4). The antenna radiator (360) may include a conductive portion (510), a ground portion (520), and a conductive portion (530).

[0073] Referring to Fig. 8b, example (850) represents a radiation pattern of an antenna radiator (360). A relatively strong radiation pattern can be confirmed from the feeding portion (510) to a region (877) of the conductive portion (530). The region (877) of the conductive portion (530) can be referred to as an open point in a PIFA type antenna. RF signals provided from the feeding portion (510) can be transmitted to the region (877) through the conductive portion (530). The RF signals can be radiated to the outside through the conductive portion (530).

[0074] Referring to FIG. 8C, a user may wear an electronic device (100). The electronic device (100) may include an antenna radiator (360). Considering the feeding direction of the antenna radiator (360) in example (850), the signal intensity in one area (877) of the conductive portion (530) may be relatively stronger than the signal intensity in another area of ​​the conductive portion (530). If a part (803) of the body of the user wearing the electronic device (100) (e.g., a hand) is located in an area where the signal intensity is strong, the radiated signal may be affected.

[0075] In one embodiment, a portion of the conductive portion (530) of the antenna radiator (360) may be positioned adjacent to a specific portion of the frame (106). For example, the electronic device (100) may include at least one fastening member (e.g., fastening member (150, 160) of FIG. 1). The frame (106) may include a first portion (811) for wearing the electronic device (100) (or may be referred to as a first strap portion), a second portion (812) for wearing the electronic device (100) (or may be referred to as a second strap portion), and a side portion (813) between the first portion (811) and the second portion (812). As an example, the first portion (811) may be coupled with the fastening member (150). The second portion (812) may be coupled with the fastening member (160). For example, the fastening member (150) may be a strap. The fastening member (150) and the fastening member (160) are illustrated as separate members, but one part of one member may be connected to the first part (811) and the other part of the member may be connected to the second part (812). When looking at the display of the electronic device (100), the first part (811) may be adjacent to the first side of the electronic device (100). When looking at the display of the electronic device (100), the first part (811) may be adjacent to the second side of the electronic device (100). For example, with respect to one plane (e.g., an xy plane), the first side may face upward (e.g., in the (-) x-axis direction) and the second side may face downward (e.g., in the (+) x-axis direction). The antenna radiator (360) may function as a PIFA type antenna. A portion of the conductive portion (530) may be adjacent to the first portion (811) or the second portion (812) among the first portion (811), the second portion (812), and the side portion (813). A signal radiated from the side portion (813) may be influenced by a part of the user's body (803) (e.g., a hand or an arm).To reduce this influence, a portion of the conductive portion (530) (e.g., a region (877) of FIG. 8B) may be positioned adjacent to the first portion (811) or the second portion (812). The antenna radiator (360) may be positioned such that the portion of the conductive portion (530) faces an open direction (e.g., a (-) axis direction, a (+) x-axis direction) rather than a direction in which a part of the body (803) is located. For example, the portion may include an open area (i.e., an open point) in a PIFA type antenna. For example, the portion of the conductive portion (530) may include a point of the conductive portion (530) that is farthest from the ground portion (520) of the antenna radiator (360). For example, a portion of the conductive portion (530) may include a point of the conductive portion (530) that is furthest from the feed portion (510) of the antenna radiator (360). For example, a portion of the conductive portion (530) may include a point of the conductive portion (530) that is furthest from the area that includes the feed portion (510) and the ground portion (520) of the antenna radiator (360).

[0076] FIG. 9 is a cross-sectional view of an exemplary electronic device (e.g., electronic device (100)). Like reference numerals may represent like descriptions.

[0077] Referring to FIG. 9, an example (900) is a drawing of an electronic device (100) viewed in the (-) x-axis direction. The electronic device (100) may include a PCB (340). An example (950) is a drawing of a region of the electronic device (100) including an antenna radiator (360) viewed in the (-) x-axis direction. The electronic device (100) may include a non-conductive support portion (350). A portion of the non-conductive support portion (350) may include a surface facing one direction (e.g., the (-) z-axis direction). At least a portion of the antenna radiator (360) (e.g., the conductive portion (530)) may be disposed on the portion. For example, the conductive portion (530) may be disposed to radiate a signal toward the (-) z-axis direction. The (-) z-axis direction may be referred to as a rear direction. The electronic device (101) may include a rear plate (107) positioned toward the rear. For example, the rear plate (107) may come into contact with a part of the user's body (e.g., a wrist) when the user wears the electronic device (101). The user's biometric data may be measured through a sensor (e.g., a heart rate monitor (HRM) module) positioned on the rear plate (107).

[0078] Although not shown in FIG. 9, the feed portion (510) and the ground portion (520) of the antenna radiator (360), which are connected to the conductive portion (530), may be coupled to the PCB (340). For example, the antenna radiator (360) may be formed of FPCB. The antenna radiator (360) may pass through a hole (not shown) of the non-conductive support portion (350). A portion of the antenna radiator (360) may pass through the hole of the non-conductive support portion (350) and then be connected to the PCB (340) through a connecting member (e.g., the first connecting portion (610)). Another portion of the antenna radiator (360) may pass through the hole of the non-conductive support portion (350) and then be connected to the PCB (340) through a connecting member (e.g., the second connecting portion (620)).

[0079] Figures 10a and 10b illustrate radiation performance according to the connection location between the ground of a PCB (e.g., PCB (340)) and a metal frame. The same reference numbers may indicate the same description.

[0080] Referring to FIG. 10A, the electronic device (100) may include a frame (106), a PCB (340), and an antenna radiator (360). The antenna radiator (360) may include a feeding portion (510), a ground portion (520), and a conductive portion (530) for connecting the feeding portion (510) and the ground portion (520). The electronic device (100) may include a feeding portion (501) and a ground (502). The feeding portion (510) of the antenna radiator (360) may be electrically connected to the feeding portion (501) of the PCB (340). The ground portion (520) of the antenna radiator (360) may be electrically connected to the ground (502) of the PCB (340). For example, the power supply (501) may be understood as a portion of a power supply line connected to a wireless communication circuit on the second side of the PCB (340) (e.g., the second side (442) of the PCB (340) in FIG. 4). The ground (502) may be understood as a portion on the second side (442) of the PCB (340) that is connected via a ground path (e.g., a ground path (740)) that is connected to the ground layer of the PCB (340).

[0081] The ground (502) of the PCB (340) can be electrically connected to another conductor (e.g., the frame (106)) that provides a reference potential. For example, for the ground (502) of the PCB (340), the PCB (340) can be connected to the frame (106) at one point. For example, among the multiple layers of the PCB (340), at least one layer (hereinafter, the ground layer) can be connected to the frame (106) at one point. The ground layer can be electrically connected to the ground (502) of the PCB (340). Example (1001) shows that the PCB (340) and the frame (106) are grounded at a first area (1011) corresponding to approximately the 5 o'clock direction when the (-) x-axis direction is assumed to be 12 o'clock based on a plane. Example (1002) shows that the PCB (340) and the frame (106) are grounded in the second region (1012) corresponding to approximately 1 o'clock when the (-) x-axis direction is assumed to be 12 o'clock with respect to one plane. Example (1003) shows that the PCB (340) and the frame (106) are grounded in the first region (1011) corresponding to approximately 5 o'clock and the third region (1013) corresponding to approximately 7 o'clock when the (-) x-axis direction is assumed to be 12 o'clock with respect to one plane. Example (1004) shows that the PCB (340) and the frame (106) are grounded in the first region (1011) corresponding to approximately 5 o'clock, the second region (1012) corresponding to approximately 1 o'clock, and the third region (1013) corresponding to approximately 7 o'clock when the (-) x-axis direction is assumed to be 12 o'clock with respect to one plane.

[0082] Referring to FIG. 10b, a graph (1050) may represent total efficiency for frequency. The horizontal axis of the graph (1050) represents frequency (unit: GHz) and the vertical axis of the graph (1050) represents total efficiency (unit: dB). The electronic device (100) may include an antenna radiator (360). The antenna radiator (360) may function as a radiator of a PIFA type antenna. A first line (1001) represents total efficiency corresponding to the first example (1001) of FIG. 10a. A second line (1002) represents total efficiency corresponding to the second example (1002) of FIG. 10a. A third line (1003) represents total efficiency corresponding to the third example (1003) of FIG. 10a. The fourth line (1004) represents the overall efficiency corresponding to the fourth example (1004) of Fig. 10a. The fifth line (1005) represents the overall efficiency when the PCB (340) connected to the antenna radiator (360) of Fig. 10a is not grounded to the frame (106).

[0083] Referring to the graph (1050), it can be confirmed that the resonant frequency shifts as the grounding position between the PCB (340) and the frame (106) changes. A design that considers the shift of the resonant frequency and the improvement of the isolation between antennas (e.g., a metal antenna using the frame (106) and a PIFA antenna using the antenna radiator (360)) through the change of the grounding position can be used. As an example, let us assume that the frequency of the target frequency band is approximately 1.2 GHz. The highest overall efficiency performance can be confirmed in the second example (1002). The overall efficiency performance can be increased as the position of the ground (502) on the PCB (340) connected to the ground portion (520) of the antenna radiator (360) is close to the position where the PCB (340) and the frame (106) are grounded. In one embodiment, the ground (e.g., ground layer) of the PCB (340) may be grounded to a portion extending from a portion of the frame (106). The portion of the frame to be grounded may be within a critical range from the ground portion (520) when looking at a second side of the PCB (340) (e.g., a side of the PCB (340) facing the (-) z-axis, the second side (442) of the PCB (340) in FIG. 4).

[0084] Figures 11a, 11b, and 11c illustrate the radiation performance of an antenna radiator (e.g., antenna radiator (360)) including an additional conductive portion. Like reference numerals may represent like descriptions.

[0085] Referring to FIG. 11A, the electronic device (100) may include an antenna radiator (360). The antenna radiator (360) may include a conductive portion (510), a ground portion (520), a conductive portion (530), and an additional conductive portion (1130). A first region (1131) of the additional conductive portion (1130) may be connected to the conductive portion (530). A second region (1132) of the additional conductive portion (1130) may be connected to the conductive portion (530).

[0086] Referring to FIG. 11b, example (1150) illustrates a radiation pattern of an antenna radiator (360). A radiation pattern having a certain signal intensity or higher can be confirmed not only in the conductive portion (530) but also in an area adjacent to an additional conductive portion (1130) in the feeding portion (510). The antenna radiator (360) can have an expanded radiation pattern through a shape that divides the paths of the conductor through which the current applied to the feeding portion (510) can flow (e.g., a closed loop shape).

[0087] Referring to FIG. 11C, a graph (1170) may represent radiation efficiency and total efficiency with respect to frequency. Radiation efficiency may represent the ratio of radiated power to power input to the antenna. Total efficiency may represent the ratio of radiated power to total power consumed by the antenna. For example, the total efficiency may be determined as a value obtained by multiplying the radiation efficiency by the impedance matching efficiency. The horizontal axis of the graph (1050) represents frequency (unit: GHz) and the vertical axis of the graph (1170) represents total efficiency (unit: dB). A first line (1181) represents the radiation efficiency of an antenna radiator (360) (e.g., the antenna radiator (360) of FIG. 5) that includes only a feeding portion (510), a ground portion (520), and a conductive portion (530) without including an additional conductive portion (1130). The second line (1182) represents the radiation efficiency of an antenna radiator (360) including a feed portion (510), a ground portion (520), a conductive portion (530), and an additional conductive portion (1130) (e.g., the antenna radiator (360) of FIGS. 11A and 11B). The third line (1191) represents the overall efficiency of an antenna radiator (360) including only a feed portion (510), a ground portion (520), and a conductive portion (530) without including an additional conductive portion (1130) (e.g., the antenna radiator (360) of FIG. 5). The fourth line (1192) represents the overall efficiency of the antenna radiator (360) (e.g., the antenna radiator (360) of FIGS. 11A and 11B) including the feed portion (510), the ground portion (520), the conductive portion (530), and the additional conductive portion (1130).

[0088] Comparing the first line (1181) and the second line (1182) in the graph (1170), it can be confirmed that the radiation efficiency increases as the additional conductive portion (1130) is included. Comparing the third line (1191) and the fourth line (1192) in the graph (1170), it can be confirmed that the overall efficiency increases as the additional conductive portion (1130) is included.

[0089] Fig. 12 illustrates an example of an antenna radiator (e.g., antenna radiator (360)) using a flexible printed circuit board (FPCB) for a sensor circuit. The same reference numbers may indicate the same description.

[0090] Referring to FIG. 12, the electronic device (100) may include a sensor circuit (380). For example, the sensor circuit (380) may include a heart rate monitor (HRM) module. A processing circuit (e.g., a processor (1320) of FIG. 13) may be disposed on a PCB (340). The electronic device (100) may include components for electrical connection between the processing circuit and the sensor circuit (380). For example, the electronic device (100) may include an FPCB (1260) connected to the sensor circuit (380). According to one embodiment, as in example (1210), the FPCB (1260) connected to the sensor circuit (380) may be used as an antenna radiator (360). In other words, one area of ​​the FPCB (1260) for the sensor circuit (380) (e.g., HRM module) may be connected to the power supply part (501) of the PCB (340) and one end may be connected to the ground (502) of the PCB (340). At least a portion of the FPCB (1260) may have a 'U' shape. In addition, according to one embodiment, as in example (1250), at least a portion of the FPCB (1260) may be used to electrically connect the sensor circuit (380) and the processing circuit on the PCB (340). The FPCB (1260) is an antenna radiator (360), and in a PIFA type antenna, the antenna length (e.g., the distance from the ground part to the open point) is / 4) may have a conductive portion having a length to secure a power supply portion (510), a ground portion (520), and a shape for connecting a sensor circuit (380) and a processing circuit.

[0091] In the present disclosure, a structure in which an antenna radiator (360) is arranged on a rear area of ​​an electronic device (100) is described through FIGS. 1 to 12. The antenna radiator (360) may be configured to radiate in a rear direction (e.g., a direction in which a user's body touches it). The antenna radiator (360) may be coupled to a PCB (340) to form a loop. The antenna radiator (360) has a single feed structure, and since an end of the antenna radiator (360) is electrically connected to the ground, it may function as a PIFA type antenna. Even if the positions of the feed portion (510) and the ground portion (520) are swapped, or the antenna radiator (360) rotates around the center of the electronic device (100), unlike the drawings illustrated through FIGS. 1 to 12, it may be understood as an embodiment of the present disclosure. This is because, if the end of the antenna radiator (360) in a single-feed structure is connected to ground and includes a 'U'-shaped conductive portion (530), it can function as a PIFA type antenna within a restricted space.

[0092] In embodiments, an electronic device (100) is provided. The electronic device (100) includes a display (120) for a front surface; a frame (106) for a side surface; a printed circuit board (PCB) (340), the PCB (340) including a first surface (441) facing the front surface and a second surface (442) facing the rear surface; an antenna radiator (360), the antenna radiator (360) including a conductive portion (530), a feeding portion (510) located at one end of the antenna radiator (360), and a ground portion (520) located at the other end of the antenna radiator (360), and a first connecting portion (610) contacting the feeding portion (510) of the antenna radiator (360) on the second surface of the PCB (340); And it may include a second connection portion (620) that contacts the ground portion (520) of the antenna radiator (360) on the second surface of the PCB (340). The antenna radiator (360) may be arranged such that, when looking at the second surface of the PCB (340), the feeding portion (510) and the ground portion (520) are adjacent to the first side of the electronic device (100), and at least a portion of the conductive portion (530) is adjacent to the second side of the electronic device (100) opposite to the first side. At least a part of the conductive portion may be arranged adjacent to the first portion or the second portion among a first portion (e.g., a portion connected to the fastening member (e.g., a strap)) for connecting to a member for wearing the electronic device (e.g., a fastening member (150)), a second portion (e.g., a portion connected to the fastening member (e.g., a strap)) for connecting to a member for wearing the electronic device (e.g., a fastening member (160)), and a side portion between the first portion and the second portion.

[0093] In embodiments, an electronic device (100) is provided. The electronic device (100) includes a display (120) for a front surface; a frame (106) for a side surface; a printed circuit board (PCB) (340), the PCB (340) including a first surface (441) facing the front surface and a second surface (442) facing the rear surface; an antenna radiator (360), the antenna radiator (360) including a conductive portion (530), a feeding portion (510) extending from the conductive portion (530), and a ground portion (520) extending from the conductive portion (530), and a first connection portion (610) contacting the feeding portion (510) of the antenna radiator (360) on a second surface of the PCB (340); And it may include a second connection portion (620) that contacts the ground portion (520) of the antenna radiator (360) on the second surface of the PCB (340). The antenna radiator (360) may be arranged such that, when looking at the second surface of the PCB (340), the feeding portion (510) and the ground portion (520) are adjacent to the first side of the electronic device (100), and at least a portion of the conductive portion (530) is adjacent to the second side of the electronic device (100) opposite to the first side. At least a part of the conductive portion may be arranged adjacent to the first portion or the second portion among a first portion (e.g., a portion connected to the fastening member (e.g., a strap)) for connecting to a member for wearing the electronic device (e.g., a fastening member (150)), a second portion (e.g., a portion connected to the fastening member (e.g., a strap)) for connecting to a member for wearing the electronic device (e.g., a fastening member (160)), and a side portion between the first portion and the second portion.

[0094] For example, the electronic device (100) may include a wireless communication circuit arranged on the PCB (340). The feeding portion (510) of the antenna radiator (360) may be electrically connected to the wireless communication circuit through the first connection portion (610). The ground portion (520) of the antenna radiator (360) may be electrically connected to the ground of the PCB (340) through the second connection portion (620). At least a portion of the antenna radiator (360) may be arranged to be spaced apart from the second surface of the PCB (340).

[0095] For example, the electronic device (100) may include a global positioning system (GPS) processing circuit. The wireless communication circuit may be configured to transmit or receive signals in a cellular frequency band via the antenna radiator (360). The GPS processing circuit may be configured to receive GPS signals via at least a portion of the frame (106).

[0096] For example, the electronic device (100) may include a second wireless communication circuit. The wireless communication circuit may be configured to transmit or receive signals in a frequency band of a first frequency range through the antenna radiator (360). The second wireless communication circuit may be configured to transmit or receive signals in a frequency band of a second frequency range higher than the first frequency range through at least a portion of the frame (106). The first frequency range may include Band 14. For example, the ground of the PCB (340) may be grounded at a portion extending from a portion of the frame (106). The portion of the frame (106) may be located within a critical range from the ground portion (520) of the antenna radiator (360) when looking at the second surface of the PCB (340).

[0097] For example, the electronic device (100) may include a switching circuit for a ground portion (520) of the antenna radiator (360). The switching circuit may be configured to electrically connect one of a plurality of elements to the ground portion (520).

[0098] For example, the electronic device (100) may include a non-conductive support portion. The non-conductive support portion may be disposed between the PCB (340) and the conductive portion (530). The feed portion (510) of the antenna radiator (360) may be connected to a portion that extends from the conductive portion (530) and passes through a hole of the non-conductive support portion. The ground portion (520) of the antenna radiator (360) may be connected to a portion that extends from the conductive portion (530) and passes through another hole of the non-conductive support portion. For example, the electronic device (100) may be disposed in front of the display (120) and may include a first plate for the front of the electronic device (100); a sensor circuit used for heart rate monitoring (HRM); and a second plate for the back of the electronic device (100).

[0099] For example, at least a portion of the antenna radiator (360) may be used to electrically connect the sensor circuit and the processing circuit on the PCB (340). For example, the frame (106) may include a first portion for wearing the electronic device (100), a second portion for wearing the electronic device (100), and a side portion between the first portion and the second portion. At least a portion of the antenna radiator (360) may be disposed adjacent to the first portion or the second portion among the first portion, the second portion, and the side portion of the frame (106).

[0100] For example, the first side may correspond to the first portion of the frame, and the second side may correspond to the second portion of the frame.

[0101] For example, the antenna radiator (360) may include an additional conductive portion (530) formed to extend from each of the first region and the second region of the conductive portion (530). The additional conductive portion (530) may be positioned to be spaced apart from the second side of the PCB (340). When looking at the second side of the PCB (340), the additional conductive portion (530) may be adjacent to the second side opposite the first side.

[0102] For example, at least a portion of the antenna radiator (360) may have a 'U' shape.

[0103] For example, the antenna radiator (360) may include a flexible printed circuit board (FPCB). The height of at least a portion of the conductive portion (530) from the PCB (340) may be higher than the height of the power supply portion (510) from the PCB (340) and the height of the ground portion (520) from the PCB (340).

[0104] For example, the distance between the area closest to the second side among the conductive portions (530) of the antenna radiator (360) and the ground portion (520) of the antenna radiator (360) may be at least 1 / 4 of the wavelength of the signal radiated through the antenna radiator (360).

[0105] In embodiments, an electronic device (100) is provided. The electronic device (100) may include a display (120) for a front surface; and a frame (106) for a side surface; a printed circuit board (PCB) (340), the PCB (340) including a first surface (441) facing the front surface and a second surface (442) facing the rear surface; an antenna radiator (360); a first wireless communication circuit disposed on the PCB (340); and a second wireless communication circuit disposed on the PCB (340). A first end (e.g., a power supply portion (510)) of the antenna radiator (360) may be electrically connected to the first wireless communication circuit, and a second end (e.g., a ground portion (520)) of the antenna radiator (360) may be electrically connected to a ground of the PCB (340). A first portion of the frame (106) may be electrically connected to the second wireless communication circuit, and a second portion of the frame (106) may be electrically connected to the ground of the PCB (340). At least a portion of the antenna radiator (360) may be arranged to be spaced apart from the second surface of the PCB (340). The frame may include a first portion for connecting to a wearable member of the electronic device, a second portion for connecting to a wearable member of the electronic device, and a side portion between the first portion and the second portion. A region of the antenna radiator that is furthest from the second end may be arranged to be adjacent to the first portion or the second portion of the frame.

[0106] For example, the first wireless communication circuit may be configured to transmit or receive signals in a frequency band of a first frequency range via the antenna radiator (360). The second wireless communication circuit may be configured to transmit or receive signals in a frequency band of a second frequency range higher than the first frequency range via at least a portion of the frame (106). The first frequency range may include Band 14.

[0107] For example, the electronic device (100) may include a switching circuit for the ground of the PCB (340) and the second end (e.g., ground portion (520)) of the antenna radiator (360). The switching circuit may be configured to electrically connect one of a plurality of elements to the second end (e.g., ground portion (520)).

[0108] For example, the electronic device (100) may include a global positioning system (GPS) processing circuit. The GPS processing circuit may be configured to receive GPS signals through at least a portion of the frame (106).

[0109] For example, the frame (106) may include a first portion for wearing the electronic device (100), a second portion for wearing the electronic device (100), and a side portion between the first portion and the second portion. The antenna radiator (360) may be arranged such that, when looking at the second surface of the PCB (340), the first end (e.g., the feeding portion (510)) and the second end (e.g., the ground portion (520)) of the antenna radiator (360) are adjacent to the first portion, and at least a portion of the antenna radiator (360) is adjacent to the second portion.

[0110] For example, the first portion may correspond to a first side of the electronic device, and the second portion may correspond to a second side of the electronic device opposite to the first side. The first end and the second end may be adjacent to the first portion in the frame.

[0111] For example, the antenna radiator (360) may be a flexible printed circuit board (FPCB). The height of at least a portion of the antenna radiator (360) from the PCB (340) may be higher than the height of the first end (e.g., the feeding portion (510)) from the PCB (340) and the height of the second end (e.g., the ground portion (520)) from the PCB (340).

[0112] The electronic device (100) described above with reference to FIGS. 1 to 12 may be understood as an example of an electronic device described below. Hereinafter, possible components of the electronic device or components of an electronic device connectable to the electronic device are described with reference to FIG. 13.

[0113] Figure 13 is a block diagram of an electronic device within a network environment.

[0114] Referring to FIG. 13, in a network environment (1300), an electronic device (1301) may communicate with an electronic device (1302) via a first network (1398) (e.g., a short-range wireless communication network), or may communicate with at least one of an electronic device (1304) or a server (1308) via a second network (1399) (e.g., a long-range wireless communication network). According to one embodiment, the electronic device (1301) may communicate with the electronic device (1304) via the server (1308). According to one embodiment, the electronic device (1301) may include a processor (1320), a memory (1330), an input module (1350), an audio output module (1355), a display module (1360), an audio module (1370), a sensor module (1376), an interface (1377), a connection terminal (1378), a haptic module (1379), a camera module (1380), a power management module (1388), a battery (1389), a communication module (1390), a subscriber identification module (1396), or an antenna module (1397). In some embodiments, the electronic device (1301) may omit at least one of these components (e.g., the connection terminal (1378)), or may have one or more other components added. In some embodiments, some of these components (e.g., sensor module (1376), camera module (1380), or antenna module (1397)) may be integrated into a single component (e.g., display module (1360)).

[0115] The processor (1320) may, for example, execute software (e.g., a program (1340)) to control at least one other component (e.g., a hardware or software component) of the electronic device (1301) connected to the processor (1320) and perform various data processing or operations. According to one embodiment, as at least a part of the data processing or operations, the processor (1320) may store commands or data received from other components (e.g., a sensor module (1376) or a communication module (1390)) in a volatile memory (1332), process the commands or data stored in the volatile memory (1332), and store result data in a non-volatile memory (1334). According to one embodiment, the processor (1320) may include a main processor (1321) (e.g., a central processing unit or an application processor) or a secondary processor (1323) (e.g., a graphics processing unit, a neural processing unit (NPU), an image signal processor, a sensor hub processor, or a communication processor) that can operate independently or together with the main processor (1321). For example, when the electronic device (1301) includes the main processor (1321) and the secondary processor (1323), the secondary processor (1323) may be configured to use less power than the main processor (1321) or to be specialized for a given function. The secondary processor (1323) may be implemented separately from the main processor (1321) or as a part thereof.

[0116] The auxiliary processor (1323) may control at least a portion of functions or states associated with at least one component (e.g., the display module (1360), the sensor module (1376), or the communication module (1390)) of the electronic device (1301), for example, on behalf of the main processor (1321) while the main processor (1321) is in an inactive (e.g., sleep) state, or together with the main processor (1321) while the main processor (1321) is in an active (e.g., application execution) state. In one embodiment, the auxiliary processor (1323) (e.g., an image signal processor or a communication processor) may be implemented as a part of another functionally related component (e.g., a camera module (1380) or a communication module (1390)). In one embodiment, the auxiliary processor (1323) (e.g., a neural network processing unit) may include a hardware structure specialized for processing artificial intelligence models. The artificial intelligence models may be generated through machine learning.
