Description

[0001] This application is a divisional application of a patent application with an application date of August 30, 2018, application number 201880056077.7, and titled “Antenna for Wearable Devices”. Technical Field

[0002] The present disclosure relates to an antenna for a wearable device. Background Art

[0003] With the advent of user devices such as smartphones and tablet computers, wearable electronic devices have become widely available. Such wearable electronic devices include antennas for wireless communication.

[0004] Generally speaking, currently available wearable electronic devices include antennas for supporting global navigation satellite systems (GNSS). For example, a wearable electronic device may include a global positioning system (GPS) antenna. In addition, a Bluetooth antenna for communicating with a parent device such as a smartphone and a cellular network antenna for supporting third generation (3G) or long term evolution (LTE) communications may be further included in the wearable electronic device.

[0005] For example, in the case of a conventional smartwatch, the GPS antenna may be implemented by a monopole-shaped metal structure mounted within a strap connected to the smartwatch, or by inserting a patch antenna into the smartwatch. Alternatively, the GPS antenna may be implemented by indirect feeding (e.g., coupled feeding) where the metal structure is located on the front surface of the smartwatch.

[0006] The above information is presented as background information to assist in understanding the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with respect to the present disclosure. Summary of the Invention

[0007] Technical issues

[0008] Due to the limited internal space of wrist-worn electronic devices such as smartwatches, it is difficult to install multiple antennas. In particular, even if antennas are installed, it is difficult to ensure sufficient performance. This problem occurs in various wearable devices with limited installation space, such as ankle-mounted electronic devices, chest-mounted electronic devices, neck-mounted electronic devices, and head (face)-mounted electronic devices.

[0009] In existing antenna implementations, when a monopole antenna is mounted within a band, radiation performance can be significantly reduced by attaching the band to the wrist. Patch antennas offer excellent efficiency and directivity. However, since the antennas occupy a large space, their application in the latest smartwatches equipped with various functions and sensors is difficult. Antennas using coupled feeds face challenges in miniaturization and efficiency, as the coupling structure must be implemented within a limited space.

[0010] Technical Solution

[0011] Aspects of the present disclosure address at least the above-mentioned problems and / or disadvantages and provide at least the advantages described below. Therefore, one aspect of the present disclosure is to provide an antenna for an electronic device, which addresses the above-mentioned problems and the issues raised in the present disclosure.

[0012] According to one aspect of the present disclosure, a wearable device that can be mounted on a user's wrist may include: a housing including a metal structure; a display located within the housing, wherein the display includes a metal layer located within the metal structure and separated from the metal structure by a gap; and a printed circuit board (PCB) located within the housing and including a grounding area and a control circuit, the control circuit being located on the PCB and configured to feed power to a first point on the metal structure. The metal layer may be electrically connected to the grounding area of ​​the PCB at a second point spaced a given angle from the first point.

[0013] Beneficial effects

[0014] According to various embodiments of the present disclosure, an antenna with high efficiency and directivity may be implemented using a metal structure and a metal case of a display in a wearable electronic device.

[0015] Furthermore, the user experience can be improved by changing the antenna's radiation pattern according to various operating conditions.

[0016] Furthermore, various effects directly or indirectly understood through the present disclosure can be provided.

It should also be understood that, unless clearly defined in this manner in the various embodiments of the present disclosure, terms defined in dictionaries and commonly used should also be interpreted as customary terms in the relevant related related technologies, rather than idealized or overly formal terms. In some cases, even if terms are defined in the present disclosure, they cannot be interpreted as excluding embodiments of the present disclosure.

[0052] Hereinafter, electronic devices according to various embodiments will be described with reference to the accompanying drawings. In the present disclosure, the term "user" may refer to a person who uses an electronic device, or may refer to a device (eg, an artificial intelligence electronic device) that uses the electronic device.

[0053] Figure 1 is an exploded perspective view of a wrist-worn electronic device according to an example embodiment. Figure 1 In the present disclosure, the wrist-worn electronic device can be understood as a smart watch. In this disclosure, the term "wrist-worn electronic device" or "smart watch" can be simply referred to as a "wearable device".

[0054] refer to Figure 1 , the wearable device 100 may include a housing 120 , a display 130 , a bracket 140 , a battery 150 , a printed circuit board (PCB) 160 , and a back cover 170 .

[0055] The housing 120 can protect various components (eg, the display 130, the battery 150, the PCB 160, etc.) located within the wearable device 100. Components corresponding to the housing 120 can be Figure 1Although not shown in FIG, the housing 120 may be understood as including all components constituting the housing of the wearable device 100. In an embodiment, the housing 120 may include a bezel wheel 110 positioned around a through-hole through which the display 130 is exposed. In addition, the housing 120 may be understood as including a cover glass located above the display 130, a back cover 170, and the like.

[0056] According to an embodiment, at least a portion of the housing 120 may be implemented with a conductive material such as a metal. For example, a partial area of ​​the housing 120 that forms the front surface of the wearable device 100 may be implemented with a ring-shaped metal structure. The metal structure may be electrically connected to a control circuit (e.g., a processor including various processing circuits, such as but not limited to an application processor (AP), a communication processor (CP), etc.) located on the PCB 160, and the control circuit may feed the metal structure so that the metal structure operates as an antenna radiator. In an embodiment, the bezel wheel 110 may be implemented by metal and may correspond to the above-mentioned metal structure. In another embodiment, a partial area of ​​the housing 120 that forms the front surface and / or side surface of the wearable device 100 may be implemented with a metal structure. In the present disclosure, for the sake of convenience of description, it is assumed that a partial area of ​​the housing 120 that forms the front surface of the wearable device 100 has a ring-shaped metal structure.

[0057] In embodiments, the bezel wheel 110 may prevent and / or reduce a black matrix (BM) area of ​​the display 130 from being exposed to the outside, and a user may generate a user input by rotating the bezel wheel 110 .

[0058] In an embodiment, the display 130 may have a disk shape of a specific thickness as a whole and may output images, text, etc. For another example, at least a portion of the display 130 may be exposed to the outside through the first surface of the housing 120 facing the first direction. In an embodiment, the display 130 may include a touch panel. For example, the display 130 may have a multi-layer structure including a display panel, a touch panel, a polarizer, a shielding layer, etc.

[0059] In an embodiment, the shielding layer of the display 130 may be implemented using a metal material. For example, to minimize and / or reduce noise that may occur in the display 130 and affect various components located on the PCB 160, a copper (Cu) sheet may be located on the rear surface of the display 130. The shielding layer of the metal material may be used to improve the performance of the antenna. In this disclosure, the shielding layer of the metal material may be simply referred to as a "metal layer."

[0060] In an embodiment, the display 130 may be electrically connected to the PCB 160 through a signal line for transmitting / receiving data. Also, the display 130 may be connected to a ground of the PCB 160 through a signal line or through a separate electrical path.

[0061] In one embodiment, bracket 140 may be used to mount and support internal components such as display 130, battery 150, and PCB 160. Bracket 140 may be implemented using a non-conductive material (eg, plastic).

[0062] In an embodiment, the battery 150 may be mounted on the bracket 140 and may be electrically connected to the PCB 160. The battery 150 may be charged by an external power source and may output the charged power to provide power for operation of the wearable device 100.

[0063] In an embodiment, the PCB 160 may include modules, chips, etc. required to drive the wearable device 100. For example, the PCB 160 may include a processor, a memory, a communication circuit, and the like.

[0064] In an embodiment, PCB 160 may include a plurality of layers, and one of the plurality of layers may serve as a ground for the antenna.

[0065] In an embodiment, the back cover 170 may be connected to the housing 120 to fix and protect internal components. The back cover 170 may be formed of a non-metallic material or a non-conductive material.

[0066] Figure 2 is a diagram illustrating metal structures, feed locations, and grounding associated with a display according to an embodiment. Figure 2 The configuration of the wearable device 100 is shown as a portion associated with the operation of the antenna. Figure 2 In the present disclosure, it is assumed that the display 130 and the metal structure 101 are in the form of a closed circle. However, various embodiments of the present disclosure can be applied to the case where the shape of the wearable device can be, for example, but not limited to, a rectangle, an ellipse, or any other shape.

[0067] refer to Figure 2 , power can be supplied from the PCB 160 to the first point "A" of the metal structure 101. For example, the control circuit located on the PCB 160 can directly feed power to the metal structure 101 through a conductive connection member such as a C-clip.

[0068] To provide an image signal to the display 130, the PCB 160 may be connected to a second point B' of the display 130 via a cable. The metal layer included in the display 130 may be grounded via the cable. For example, a ground line included in the cable may electrically connect a ground region (or ground layer) provided in the PCB 160 and the metal layer of the display 130. However, in embodiments, the cable may be understood as including a flexible printed circuit board (FPCB), or may be replaced with an FPCB.

[0069] The metal structure 101 may be connected to a ground region of the PCB 160 at a third point "B." In an embodiment, the metal structure 101 may selectively connect to the ground region of the PCB 160 at multiple points. For example, the metal structure 101 may include multiple switches that electrically connect the ground region of the PCB 160 to the metal structure 101. In an embodiment, the control circuit may close or open the multiple switches to connect the metal structure 101 to the ground region of the PCB 160 at one or more points. In other embodiments, the control circuit may open the multiple switches to disconnect the metal structure 101 from the ground region of the PCB 160.

[0070] The second point B' may be spaced apart from the first point 'A' by a given angle. For example, the second point B' may form an angle of 90 degrees with the first point 'A' relative to the center of the display 130. In this regard, a description will be given with reference to FIG.

[0071] Figure 3a is a diagram illustrating a feeding position of a metal structure and a ground position of a display according to an embodiment.

[0072] refer to Figure 3a , point "A" of the metal structure 101 can be fed. At any stable time, the potential of point "A" where the feeding is performed may have the highest value in the metal structure 101, while the potential of point "D" opposite (or facing) point "A" may have the lowest value in the metal structure 101. For example, point "A" can have any (+) potential value, and point "D" can have any (-) potential value. That is, (+) charge can be induced near point "A", and (-) charge can be induced near point "D".

[0073] When charge is induced in metal structure 101, an opposite charge may also be induced in the metal layer of display 130. That is, (-) charge may be induced in the area near point "A" and (+) charge may be induced in the area near point "B".

[0074] Points "B" and "C," being the center points between point "A" and point "D," correspond to points where the potential is theoretically zero. Therefore, an area adjacent to point "B" (e.g., an area surrounding point B' of display 130) may have a potential value substantially close to zero.

[0075] Therefore, when point B' is electrically connected to the ground area of ​​PCB 160 (e.g., via a cable), the impact on the current induced at display 130 (e.g., the metal layer) can be minimized and / or reduced. In other words, when feeding the metal structure 101, current can be indirectly induced (e.g., fed by coupling) even at the metal layer of display 130 adjacent to the metal structure 101. In order to minimize and / or reduce the obstruction to the flow of the current induced in the metal layer, a cable can be connected to the area around point B'. For example, the cable can be connected to the ground area of ​​PCB 160 at a position corresponding to point "B" that forms a given angle "θ" (e.g., 90 degrees) with point "A" relative to the center of display 130.

[0076] Figure 3b is a graph showing how antenna gain varies with the angle between a feed point and a cable connection point according to an embodiment. Figure 3b The gain associated with a first direction of gain of the antenna using the metal structure 101 (ie, a direction perpendicular to the plane of the display 130 ) is shown.

[0077] from Figure 3b It is understood that when the feed point and the cable connection point are at an angle of approximately 90 degrees, the gain of the antenna is maximum. Moreover, it is understood that as the angle formed by the feed point and the cable connection point becomes closer to 180 degrees, the radiation gain in the first direction decreases. Therefore, taking into account the position of the components located within the wearable device 100, interference with another antenna, and the radiation gain of the antenna, the cable connecting the display 130 and the PCB 160 can be located within an appropriate range (e.g., a range from 90 degrees to ±30 degrees).

[0078] Figure 4a is a diagram illustrating a feeding position of a metal structure and a ground position of a display according to another embodiment.

[0079] refer to Figure 4a , and reference Figure 1 3 , the wearable device 400 according to another embodiment may have a rectangular display structure with rounded corners instead of a ring-shaped display structure. Thus, unlike the metal structure 101, the metal structure 401 may also have a rectangular shape with rounded corners instead of a ring-shaped shape.

[0080] As reference Figure 3aGiven the description, power can be fed at point "A" near the left center of the metal structure 401. For ease of description, the PCB 460 included in the wearable device 400 is shown separately on the right side of the drawing. Power can be supplied to point "A" of the metal structure 401 through point "C" of the PCB 460. When points "A" and "C" are connected, point B' near the center bottom can correspond to a point where the electric potential is theoretically zero. Although in Figure 4a , but a point near the center top, corresponding to point B', may correspond to a point where the electric potential is theoretically zero. Display 130 may be electrically connected to the ground plane of PCB 460 at point B'. In the case where point B' is connected to point D', metal structure 401 may also be connected to the ground plane of PCB 460 at point "B" adjacent to point B'. In the case where point "B" and point "D" are connected, when viewed from above display 430, a first imaginary line extending from the center of display 430 to point "A" may be substantially at right angles to a second imaginary line extending from the center to point B'.

[0081] Figure 4b is a diagram illustrating a feeding position of a metal structure and a ground position of a display according to another embodiment.

[0082] exist Figure 4b In this case, point "A" feeding the metal structure 401 is located at the bottom left. In this case, the theoretical grounding point of the display 430 may correspond to point B' at the bottom right, and the display 430 may be connected to the ground plane of the PCB 460 at point B'. Theoretical Description and References Figure 3a and Figure 4a The theoretical description given is the same, so in order to avoid redundancy, no further description is repeated here. In this way, one point of the display can be connected to the ground area at an appropriate position with respect to various shapes of the display and the metal frame.

[0083] Figure 5 is a diagram showing how to feed power to a metal structure and how to connect cables to a display according to an embodiment.

[0084] refer to Figure 5 PCB 160 can feed power to one point (eg, the first point) of metal structure 101. In an embodiment, metal structure 101 can be connected to a ground area of ​​PCB 160 at multiple points directly or through a switch structure.

[0085] The display 130 may be electrically connected to the ground area of ​​the PCB 160 at one point (eg, the second point). In this case, the display 130 may not be connected to the ground area at any other point (eg, except the second point). Figure 3a 、 Figure 3b 、 Figure 4a and Figure 4b As mentioned above, the second point may correspond to a point forming an appropriate angle with the first point.

[0086] In the case where one side of the display 130 is grounded, as shown in FIG. Figure 5 As shown, charges having a first polarity (e.g., (+) polarity) can be induced in the metal structure 101 by feeding, and charges having a second polarity (e.g., (-) polarity) can be induced in the display 130 by the charges having the first polarity. As a result, the metal structure 101 and the display 130 can operate similarly to a slot antenna (e.g., a slot pattern can be formed), thereby increasing the radiation efficiency of the antenna.

[0087] In the case where the display 130 is electrically connected to the ground area of ​​the PCB 160 at two or more points, for example, in the case where the display 130 is electrically connected to the ground area of ​​the PCB 160, even in Figure 5 Inducing negative charges at the points shown in FIG. 1 may also prevent charges corresponding to the charges induced in the metal structure 101 (e.g., with opposite polarity) from being induced in the display 130. This makes it difficult to form a gap pattern between the metal structure 101 and the display 130. In this case, radiation efficiency may be reduced. In this regard, Figure 6 A graph showing the radiation efficiency is provided in .

[0088] Figure 6 is a graph illustrating radiation efficiency per frequency determined according to the number of points at which a display and a ground area are electrically connected, according to an embodiment.

[0089] exist Figure 6 In FIG, the thick solid line represents the radiation efficiency at each frequency when one point of the display 130 is grounded, and the thin solid line represents the radiation efficiency at each frequency when two points of the display 130 are grounded. It can be seen that when one point is grounded, the wearable device 100 has higher radiation efficiency in the range from 800 MHz to 2.4 MHz, which is mainly used for cellular networks, Wi-Fi networks, and GPS networks.

[0090] Figure 7a and Figure 7b is a diagram showing an example of cable connection according to the detailed structure of the display 130. For example, Figure 7a A method of connecting a pixel layer and a touch layer with a cable according to an embodiment is shown. Figure 7b A method of connecting a pixel layer and a touch layer with a cable according to another embodiment is shown.

[0091] refer to Figure 7a, the display 130 may include a copper sheet 131, a pixel layer 133, and a touch layer 135. The copper sheet 131 may correspond to the metal layer described above. The pixel layer 133 may refer to, for example, a layer in which red, green, and blue (RGB) pixels for color expression are arranged. For example, the pixel layer 133 may be understood as a layer in which pixels such as, but not limited to, LED pixels, OLED pixels, LCD pixels, etc. are arranged. The touch layer 135 may refer to, for example, a layer in which a circuit for sensing a user's touch input is placed.

[0092] Apart from Figure 7a In addition to the layers shown, the display 130 may include various layers such as polarizers, adhesive layers, pressure sensors, etc. Moreover, the touch layer 135 may be implemented integrally with the pixel layer 133. For example, embodiments of the present disclosure may be applied to on-cell or in-cell displays.

[0093] refer to Figure 7a , one point of the copper sheet 131 can be connected to the ground area of ​​the PCB 160. In addition, the pixel layer 133 can be connected to the copper sheet 131 for grounding. The touch layer 135 can also be connected to the copper sheet 131 through the pixel layer 133 for grounding.

[0094] In addition to the ground wire, the cable may include signal wires for operating the display (or pixels) and touch functions. Figure 7a In the embodiment of FIG, a cable starting from PCB 160 can be electrically connected to copper sheet 131 and pixel layer 133 at one point of display 130. Figure 7a In the embodiment, copper sheet 131 is an example, and it is understood that copper sheet 131 can be replaced by an appropriate conductive layer. For ease of description, the conductive layer will be described as copper sheet 131. Cables for driving and grounding touch layer 135 can be connected to touch layer 135 at a single point on pixel layer 133. In other words, the grounding of copper sheet 131 can be maintained at a single point, while grounding and signals are provided to both pixel layer 133 and touch layer 135.

[0095] exist Figure 7b In the example of FIG, multiple cables extending from PCB 160 can be connected to display 130. For example, a first cable can connect PCB 160 to copper sheet 131, and a second cable can connect PCB 160 to touch layer 135. Display 130 can have an internal wiring structure connecting copper sheet 131, pixel layer 133, and touch layer 135. The wiring and cable structure can be variously modified and implemented under the condition that only one point of copper sheet 131 is connected to the ground area of ​​PCB 160. For example, a first cable can connect PCB 160 to pixel layer 133, and a second cable can connect PCB 160 to touch layer 135.

[0096] Figure 7a and Figure 7b The example shown in FIG. 1 shows that the cables from PCB 160 to display 130 are integrally implemented. Compared to a conventional structure in which cables for controlling display 130 (e.g., pixel layer 133) and cables for controlling the touch screen are grounded to display 130 at different points, since display 130 is grounded at a single point, radiation efficiency can be improved in various embodiments.

[0097] Figure 8 is a graph showing how the resonant frequency varies with the gap between the display and the metal structure according to an embodiment. Figure 8 In FIG, the display 130 can be understood as a metal layer, such as a copper sheet 131. When viewed from above, Figure 8 The antenna structure shown can be understood as Figure 2 Figure 3 Figure 5 、 Figure 7a and / or Figure 7b antenna.

[0098] In an embodiment, the display 130 may include a metal layer, and the metal layer may be located within the metal structure 101 and may be spaced apart from the metal structure 101 by a given gap "d". Figure 8 1 is shown as a circle, but those skilled in the art may modify or change the embodiment so that the display 130 and the metal structure 101 may be implemented in the form of, for example but not limited to, an ellipse, a rectangle, etc.

[0099] For example, Figure 8 The graph shows the radiation efficiency when the gap "d" has a default value of 0.95mm. For example, when "d" is 0.95mm, the wearable device 100 can form a resonance at approximately 2.15GHz. When "d" is 0.3mm smaller than the default value (for example, when "d" is 0.92mm), the resonant frequency can be moved to approximately 2.05GHz. When "d" is 0.6mm smaller than the default value (for example, when "d" is 0.89mm), the resonant frequency can be moved to approximately 1.96GHz. Therefore, the resonant frequency can be finely adjusted by adjusting the size of the gap between the display 130 and the metal structure 101 of the wearable device 100.

[0100] Figure 9 is a diagram illustrating radiation patterns associated with the presence and wearing conditions of a display according to an embodiment.

[0101] exist Figure 9In the present invention, it is assumed that <Case 1> corresponds to the case where display 130 according to various embodiments operates as part of the radiator of the patch antenna, and <Case 2> corresponds to the case where display 130 does not operate as part of the radiator of the patch antenna. For comparison, <Case 2> can be understood as the case where display 130 does not exist.

[0102] exist Figure 9 In the first graph, the curve Figure 1 ” indicates radiation patterns of <Case 1> and <Case 2> in a state where the user does not wear the wearable device 100. The radiation pattern corresponding to <Case 1> is shown by a thick solid line, and the radiation pattern corresponding to <Case 2> is shown by a thin solid line. In <Case 1>, the display 130 operates as a parasitic patch antenna by coupling. As a result, compared with <Case 2> in which the display 130 does not exist, the directivity increases in the direction of the LCD (e.g., the first direction).

[0103] exist Figure 9 In the second graph, the curve Figure 2 ” indicates the radiation patterns of <Case 1> and <Case 2> in a state where the user wears the wearable device 100. In a state where the user wears the wearable device 100 on his / her wrist, radiation in the second direction (the direction opposite to the LCD direction) is restricted by the user's body, and the radiation pattern in the first direction is enhanced. That is, when the wearable device 100 is mounted on the wrist, the directivity in the first direction increases, the loss due to the wrist decreases, and thus the total gain of the antenna increases.

[0104] According to an embodiment, since one point of the display 130 functions as a parasitic patch antenna connected to the ground area, reception performance can be improved. For example, when receiving a signal such as a GPS signal from a satellite to obtain location information of the wearable device 100, the antenna's reception performance can be improved.

[0105] Figure 10a is a diagram illustrating an example in which a metal structure and a ground area are connected at multiple points according to an embodiment. Figure 10b is a diagram showing an example in which a metal structure and a ground area are not connected.

[0106] refer to Figure 10a , the metal structure 101 can be connected to the ground area via a C-clip including a switch, etc. For example, in the case where power is fed at a first point "A" of the metal structure 101, multiple points "B", "C", and "D" of the metal structure 101 can be connected to the ground area. For example, the metal structure 101 can be connected to the ground area at three different points "B", "C", and "D". The ground area can be located on the PCB 160, or can correspond to any other metal component within the wearable device 100.

[0107] exist Figure 10a In the embodiment, a circular electrical path connecting the ground area, the feed point, the ground point and the ground area can be formed. Figure 10a In the case of forming at least two ring structures, at least two ring structures can be formed along the arrow direction. Figure 10a As shown, the antenna of the wearable device 100 can have an omnidirectional radiation pattern with little directivity. That is, the antenna of the wearable device 100 can have a radiation pattern that is somewhat uniform in all directions.

[0108] Figure 10b Can correspond to Figure 10a In this case, the current induced at the metal structure 101 can make the metal layer of the display 130 act as a patch antenna. Figure 10b As shown, the antenna of the wearable device 100 can have a directional radiation pattern facing a first direction (eg, the front surface of the display 130).

[0109] The control circuit of the wearable device 100 can control the opening / shorting of a switch connected to the metal structure 101 depending on the situation. For example, since the direction of the antenna continuously changes when the user wears the wearable device 100 and walks, the control circuit can close the switch to operate the antenna in loop mode. For another example, when the user is viewing the display 130 of the wearable device 100, the control circuit can open the switch to operate the antenna in patch mode.

[0110] Mode changes can be performed based on sensors installed on the wearable device 100 or applications running in the wearable device 100. For example, the wearable device 100 may include a motion sensor that senses the movement of the wearable device 100. The motion sensor may correspond to, for example, but is not limited to, at least one or more of an accelerometer, an inertial sensor, a gyroscope sensor, and the like. If the movement sensed by the motion sensor is determined to correspond to walking or running, for example, when the circular mode is appropriate (e.g., when the direction of the antenna continuously changes), the control circuit may close the switch to cause the antenna to operate in the circular mode. However, if the direction of the display sensed by the motion sensor is determined to be facing or remaining in a specific direction, the control circuit may sense that the user is looking at the screen of the wearable device 100 and may operate the antenna in the patch mode. In another example, if the screen of the display 130 in the wearable device 100 is turned on, the control circuit may sense that the user is looking at the screen of the wearable device 100 and may operate the antenna in the patch mode.

[0111] In various embodiments, the control circuit may control a short-circuit switch connecting the metal structure 101 and the ground area. For example, the control circuit may use a motion sensor to sense the movement of the user's wrist and control the short-circuit switch so that the antenna has a directional radiation pattern whenever it is determined that the user has raised his / her hand.

[0112] Furthermore, the control circuit can switch to an antenna pattern suitable for the running application. For example, when running an application such as a golf application, a swimming application, or a running application, the wearable device 100 needs to obtain the user's accurate location via GPS. In this case, in order to receive satellite signals well, the wearable device 100 can turn on all switches so that the antenna has a directional antenna pattern.

[0113] In addition, the control circuit can use an optical sensor (e.g., a camera, an illuminance sensor, an infrared sensor, etc.) to sense whether the wearable device 100 is worn, and can control the switch so as to have different radiation patterns depending on whether the wearable device 100 is worn. Moreover, the control circuit can sense the heat generated from the wrist when the wearable device 100 is worn through a temperature sensor, and can control the switch to reduce the specific absorption rate (SAR). For example, the control circuit can control the switch so as to operate in a patch mode in which the radiation pattern is focused in the direction of the LCD, rather than a ring mode in which the radiation pattern is mainly formed in the direction of the wrist. Figure 11 Describe various examples.

[0114] Figure 10c is a diagram illustrating an example in which a metal structure is connected to a ground region through a coupling effect according to an embodiment.

[0115] refer to Figure 10c , the metal structure 101 can be indirectly connected to the ground area by coupling with the ground area. For example, the C-clip electrically connected to the metal structure 101 can be coupled to the ground area of ​​the PCB 160, or can be connected to the ground area through an additional coupling capacitor. Figure 13a and Figure 13b Describe this structure more fully.

[0116] In addition to reference Figure 10b In addition to the patch antenna described in Figure 10c In this case, a portion of metal structure 101 can be used as an additional antenna, for example by coupling an electrical path from a feed point to a ground point. In accordance with an embodiment, the metal layer of display 130 can be used as a GPS antenna, and a portion of metal structure 101 can be used as a Bluetooth or WiFi antenna.

[0117] from Figure 10cThe radiation pattern of the antenna corresponding to the case where the metal structure 101 is connected to the ground area through coupling can be observed. Figure 10b In the case shown, the antenna using the metal layer of the display 130 can have a directional radiation pattern facing a first direction (eg, the front surface of the display 130). Figure 10b Compared to the radiation pattern shown, where a portion of the metal structure 101 is used as a separate antenna, the radiation pattern at the metal layer of the display 130 is similar to the radiation pattern where the metal structure 101 is not connected to the ground area.

[0118] Figure 11 is a flow chart illustrating a switching control scenario of an antenna according to an embodiment.

[0119] refer to Figure 11 In operation 1101, the control circuit of the wearable device 100 may determine whether GPS tracking is turned on. If GPS tracking is turned off by user settings or device settings, the wearable device 100 may control the antenna to receive signals from any other network (e.g., a cellular network or a WiFi network).

[0120] When GPS tracking is turned on, in operation 1103, the wearable device 100 can sense the wearing state and / or movement of the wearable device 100. For example, the wearable device 100 can sense the wearing state and / or movement using an acceleration sensor, a gyroscope sensor, an inertial sensor, a heart rate sensor, etc.

[0121] In operation 1105, the wearable device 100 may determine an antenna mode suitable for the current state. The wearable device 100 may use the information about the wearing state and / or motion collected in operation 1103 to determine the antenna mode. Additionally or alternatively, the wearable device 100 may also utilize the operating state of the device's hardware components, the operating state of the software being executed, and the like. For example, the wearable device 100 may utilize whether the display 130 is turned on as information for determining the antenna mode. Furthermore, the wearable device 100 may utilize the currently executing application or function as information for determining the antenna mode.

[0122] For example, as referenced Figure 10a and Figure 10bAs described above, when a golf or running application is being run, the control circuit may determine that the patch mode for receiving a GPS signal well is appropriate. Alternatively, when the screen of the display 130 is turned on, the control circuit may sense that the user is looking at the screen of the wearable device 100 and may determine that it is appropriate to operate the antenna in the patch mode. In this case, in operation 1107, the wearable device 100 may disconnect the ground switches (e.g., SW1, SW2, and SW3) and may operate the antenna in the patch mode for the purpose of receiving a GPS signal well.

[0123] For another example, when the motion sensed by the motion sensor corresponds to walking or running, it can be determined that the direction of the antenna changes continuously. Therefore, the control circuit can determine that the loop mode is appropriate. In this case, in operation 1109, the wearable device 100 can close at least a portion of the ground switches (e.g., SW1, SW2, and SW3) and can operate the antenna in the loop mode.

[0124] In addition, the control circuit can receive signals in a specified frequency band by appropriately controlling the closing / opening of switches (e.g., SW1, SW2, and SW3). For example, in a first switch combination (e.g., SW1 is closed, SW2 and SW3 are disconnected), the wearable device 100 can be optimized to receive WiFi signals. For another example, in a second switch combination (e.g., SW1 and SW3 are disconnected, SW2 is closed), the wearable device 100 can be optimized to receive signals in a WCDMA band (2.1 GHz band). In addition to the loop mode and patch mode, the control circuit can ensure optimal performance by appropriately controlling the opening / closing of the switches in operation 1111 according to the current operating state.

[0125] According to an embodiment, information for controlling at least one or more switches (eg, SW1 , SW2 , and SW3 ) according to an operation state of the wearable device 100 may be stored in a memory of the wearable device 100 .

[0126] Figure 12 is a graph showing radiation efficiency of each frequency band according to the number of grounds connected between the metal structure and the ground area.

[0127] refer to Figure 12, it was observed that when the metal structure (e.g., metal structure 101) was grounded at one point, the signal efficiency was good in the range from about 1800 MHz to about 2100 MHz. It was observed that when the grounding of the metal structure was disconnected by a switch or the like, that is, when the metal structure was not grounded, the signal was good in the 1500 MHz band. Therefore, in order to improve the reception sensitivity of the GPS signal, when using GPS or when running an application where GPS is important, the control circuit can control the switch between the metal structure 101 and the ground area so that the switch is disconnected (or the metal structure 101 is not grounded).

[0128] Figure 13a is a diagram illustrating a side structure of a wearable device according to an embodiment.

[0129] Figure 13b is a diagram illustrating a side structure of a wearable device according to an embodiment.

[0130] refer to Figure 13a and Figure 13b , an electrical path can be formed between the metal structure 1350a or 1350b and the ground area of ​​the PCB 1360a or 1360b. Depending on the embodiment, the wearable device may include the metal structure 1350a or 1350b, the bracket 1340a or 1340b, or the PCB 1360a or 1360b. The bracket 1340a or 1340b can be electrically connected to a point of the metal structure 1350a or 1350b via the side clip 1320a or 1320b. The side clip 1320a or 1320b can be electrically connected to the C-clip 1310a or 1310b. According to various embodiments, the side clip 1320a or 1320b may be referred to as a "first C-clip", and the C-clip 1310a or 1310b may be referred to as a "second C-clip". For another example, the side clip 1320a or 1320b and the C-clip 1310a or 1310b may be implemented integrally.

[0131] According to the embodiment, Figure 13a As shown, a portion 1361a of a layer in PCB 1360a may be removed. In embodiments, the removal of a portion of the layer in PCB 1360a may be understood to be the same as or similar to the case where the portion of layer 1361a in PCB 1360a is formed of a dielectric. The grounding area of ​​PCB 1360a with the portion 1361a removed may be connected to C-clip 1310a via coupling. For example, the grounding area of ​​PCB 1360a may operate similarly to the grounding area being connected to C-clip 1310a via dummy coupling capacitor 1330a.

[0132] According to an embodiment, since C-clip 1310a is connected to metal structure 1350a via side clip 1320a, metal structure 1350a can be coupled to the ground area of ​​PCB 1360a. In an embodiment, since the first point of metal structure 1350a can be fed, the antenna can be used through an electrical path from the feeding point to the ground area.

[0133] According to an embodiment, the entire layer 1361b belonging to a partial area of ​​the PCB 1360b may be removed, such as Figure 13b As shown. In this case, since the entire layer 1361b is removed, the area for coupling between the C-clip 1310b and the ground area of ​​the PCB 1360b is insufficient, so it may be difficult to connect the ground area of ​​the PCB 1360b to the C-clip 1310b through coupling. To this end, the ground area and the C-clip 1310b can be connected via a capacitor 1330b having a specified capacitance (e.g., 0.5 pF to 1.0 pF). Because the C-clip 1310b can be connected to the metal structure 1350b via the side clip 1320b, the metal structure 1350b can be electrically connected to the ground area. In an embodiment, since the first point of the metal structure 1350b can be fed, at least a portion of the metal structure 1350b can be used as an antenna through the electrical path from the feed line to the ground area of ​​the PCB 1360b.

[0134] Figure 14 is a graph illustrating radiation efficiency of a wearable electronic device according to an embodiment.

[0135] refer to Figure 14 , the first graph 1410 may represent the radiation efficiency of the wearable device 100 in which the metal structure 101 is not connected to the ground area. The second graph 1420 may represent the radiation efficiency of the wearable device 100 in which the metal structure 101 is indirectly connected to the ground area of ​​the PCB 160 through coupling.

[0136] The first region 14a may represent a frequency band ranging from about 1.5 GHz to about 1.6 GHz in which GPS communication may be performed. In the first region 14a, both the first graph 1410 and the second graph 1420 may have a radiation efficiency of about -10 dB, thereby enabling efficient signal transmission / reception.

[0137] The second region 14b may represent a frequency band ranging from approximately 2.4 GHz to approximately 2.5 GHz in which Bluetooth or Wi-Fi communication can be performed. In the second region 14b, the first graph 1410 may have a radiation efficiency of approximately -16 dB, and the second graph 1420 may have a radiation efficiency of approximately -11 dB, thereby enabling efficient signal transmission / reception.

[0138] By utilizing the coupling effect to connect the metal structure 101 and the ground area of ​​the PCB 160, the wearable device according to various embodiments of the present disclosure can transmit signals with excellent efficiency in Bluetooth communication, Wi-Fi communication, and GPS communication. Therefore, it may not be necessary to separately implement a separate antenna for Bluetooth communication or a separate antenna for Wi-Fi communication. This may mean that the wearable device 100 can be further miniaturized and its cost can be reduced.

[0139] Figure 15a is a diagram illustrating a method for moving a resonance point of a wearable device according to an embodiment.

[0140] Figure 15b is a diagram illustrating a method for moving a resonance point of a wearable device according to an embodiment.

[0141] Figure 15c is a graph illustrating radiation efficiency of a wearable electronic device according to an embodiment.

[0142] refer to Figure 15a and Figure 15b , the wearable device 100 can use the coupling effect to electromagnetically connect the metal structure 101 and the ground area of ​​the PCB 160. Figure 15a The wearable device 100 shown can be used as Figure 13a The coupling between the ground area and the C-clip 1310 a is shown to electromagnetically connect, for example, the metal structure 101 and the ground area of ​​the PCB 160 . Figure 15b The wearable device 100 shown can be used as Figure 13b A capacitor 1330 b is shown between the ground region and the C-clip 1310 b to electromagnetically connect, for example, the metal structure 101 and the ground region of the PCB 160 .

[0143] like Figure 15a As shown, the resonance point of the antenna can be changed by changing the specific position of the metal structure 101 electrically connected to the ground area of ​​the PCB 160. For example, the ground area can be electromagnetically connected to the first point 15a-1, the second point 15a-2, or the third point 15a-3 of the metal structure 101. Since the length of the formed electrical path changes in each case, the resonance point of the antenna can be changed.

[0144] In an embodiment, the resonant frequency corresponding to the electromagnetic connection between the ground region and the first point 15 a - 1 of the metal structure 101 may be higher than the resonant frequency corresponding to the electromagnetic connection between the ground region and the second point 15 a - 1 of the metal structure 101. In another embodiment, the resonant frequency corresponding to the electromagnetic connection between the ground region and the third point 15 a - 3 of the metal structure 101 may be lower than the resonant frequency corresponding to the electromagnetic connection between the ground region and the second point 15 a - 2 of the metal structure 101.

[0145] like Figure 15b As shown, when the capacitance of capacitor 1510b between the ground area of ​​PCB 160 and C-clip 1310b changes, the resonance point of the antenna can be changed. For example, the resonance frequency can decrease as the capacitance value of capacitor 1510b becomes relatively large. For another example, the resonance frequency can increase as the capacitance value of capacitor 1510b becomes relatively small.

[0146] The radiation efficiency of an antenna with a shifted resonant frequency can be calculated from Figure 15c It can be observed that the resonant frequency of the first graph 1501C becomes lower than the resonant frequency of the second graph 1502C, and the resonant frequency of the third graph 1503C becomes higher than the resonant frequency of the second graph 1502C. The wearable device according to various embodiments of the present disclosure can finely adjust the resonant frequency of the antenna.

[0147] Below, we will refer to Figures 16 to 18 Hardware and software configurations applicable to the wearable device 100 according to various embodiments of the present disclosure are described.

[0148] refer to Figures 1 to 15c According to an embodiment, a wearable electronic device may include a housing including an upper surface, a lower surface, and a side surface surrounding a space between the upper surface and the lower surface. In this case, the side surface may include an annular member (e.g., metal structure 101) that is annular when viewed from above the upper surface and is formed of a conductive material. In an embodiment, the annular member may be substantially circular when viewed from above the upper surface. In another embodiment, the annular member may be substantially square or rectangular.

[0149] Furthermore, the wearable device may include a binding structure connected to the housing and removably mounted on a portion of the user's body. However, in embodiments, the binding structure may be separate from the wearable device.

[0150] The wearable device may include a display (e.g., display 130) within the space, the display including a first ground plane substantially parallel to the upper surface. The display may be exposed through the upper surface of the housing. Furthermore, the wearable device may include: a printed circuit board (e.g., PCB 160) including a second ground plane between the display and the lower surface within the space; a wireless communication circuit located on the printed circuit board and electrically connected to a first point located at the ring member (e.g., Figure 2 a first conductive path electrically connected to a second point located at an edge of the first ground plane (eg, Figure 2 between point "B" of the annular member and the second ground plane; and a second conductive path electrically connected to a third point located at the annular member (eg, Figure 2 and a processor located within the space and electrically connected to the display and the communication circuit.

[0163] Figure 16 is a block diagram illustrating electronic devices in a network environment system according to various embodiments.

[0164] refer to Figure 16 According to various embodiments, the electronic device 1601, the first electronic device 1602, the second electronic device 1604, or the server 1606 may be connected to each other via a network 1662 or a short-range communication 1664. The electronic device 1601 may include a bus 1610, a processor 1620, a memory 1630, an input / output interface 1650, a display 1660, and a communication interface 1670. Depending on the embodiment, the electronic device 1601 may not include at least one of the above components, or may further include other components.

[0165] For example, the bus 1610 may interconnect the aforementioned components 1620 to 1670 and may include circuits for transmitting communications (eg, control messages and / or data) between the aforementioned components.

[0166] The processor 1620 may include one or more of a central processing unit (CPU), an application processor (AP), or a communication processor (CP).

In addition, the kernel 1641 may provide an interface that enables the middleware 1643, API 1645, or application 1647 to access discrete components of the electronic device 1601 in order to control or manage system resources.

[0169] The middleware 1643 may perform, for example, a mediator role so that the API 1645 or the application 1647 communicates with the kernel 1641 to exchange data.

[0170] In addition, the middleware 1643 can process task requests received from the application programs 1647 according to priority. For example, the middleware 1643 can assign a priority to at least one application program 1647, which allows it to use system resources (e.g., bus 1610, processor 1620, memory 1630, etc.) of the electronic device 1601.

Electronic device 1601 can transmit the magnetic field signals to a point of sale (POS), and the POS can use an MST reader to detect the magnetic field signals. The POS can recover the data by converting the detected magnetic field signals into electrical signals.

[0177] Based on available area, bandwidth, etc., GNSS may include, for example, at least one of the Global Positioning System (GPS), the Global Navigation Satellite System (Glonass), the BeiDou Navigation Satellite System (hereinafter referred to as "BeiDou"), or the European Global Satellite-based Navigation System (hereinafter referred to as "Galileo").
