Technical Field

[0001] This application relates to the field of communication technology, and more particularly to a wearable electronic device. Background Technology

[0002] With technological advancements, wearable electronic devices with communication functions, such as rings or wristbands, typically include antenna components to enable their communication capabilities. The antenna components in these wearable electronic devices exhibit good antenna performance when the device is not worn. However, in related technologies, the antenna performance of wearable electronic devices is poor when worn on a target area of ​​the user. Summary of the Invention

[0003] In a first aspect, one embodiment of this application provides a wearable electronic device, the wearable electronic device including an antenna assembly, the antenna assembly comprising:

[0004] Radiator, the radiator comprising:

[0005] A first sub-radiator, the first sub-radiator having a first free end and a second free end, the first free end and the second free end forming a first opening, the first sub-radiator also having a first feed point; and

[0006] The second sub-radiator is stacked and spaced apart from the first sub-radiator. The second sub-radiator has a third free end and a fourth free end, which form a second opening. The second sub-radiator also has a second power supply point. When the wearable electronic device is worn on the user's target area, the second sub-radiator is closer to the target area than the first sub-radiator.

[0007] The feed source is electrically connected to the first feed point and the second feed point to excite the first sub-radiator and the second sub-radiator of the radiator to jointly support the target frequency band, and when the second sub-radiator supports the target frequency band, the second sub-radiator generates a vertical electric field.

[0008] In summary, the wearable electronic device provided in this application, through the design of the radiator in the antenna assembly of the wearable electronic device, includes a first sub-radiator and a second sub-radiator stacked and spaced apart. The first sub-radiator has a first opening, and the second sub-radiator has a second opening. The feed source is electrically connected to a first feed point of the first sub-radiator and electrically connected to a second feed point of the second sub-radiator to excite the first and second sub-radiators to jointly support the target frequency band, thereby enabling the wearable electronic device to perform communication functions in the target frequency band. When the wearable electronic device is worn on a user's target area, the second sub-radiator is closer to the target area than the first sub-radiator. Furthermore, when the second sub-radiator supports the target frequency band, it generates a vertical electric field that can excite the target area, causing the target area to radiate in the target frequency band. Therefore, when the wearable electronic device is worn, it still maintains good communication performance in the target frequency band. Attached Figure Description

[0032] The technical solution of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the embodiments described in this application are only a part of the embodiments, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments provided in this application without creative effort are within the protection scope of this application.

[0033] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0034] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a particular order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, an assembly or device comprising one or more components is not limited to the one or more components listed, but may optionally also include one or more components not listed but inherent to the exemplified product, or one or more components that it should have based on the described function.

[0035] Before introducing the wearable electronic device 1 provided in the embodiments of this application, the wearable electronic device 1 in the related art will be introduced first. It is understood that the wearable electronic device 1 in the related art is the wearable electronic device 1 prior to the improvement of the wearable electronic device 1 provided in the embodiments of this application, and the wearable electronic device 1 in the related art should not be construed as prior art.

[0036] Please see Figure 1 , Figure 2 and Figure 3 , Figure 1 A three-dimensional structural diagram of a wearable electronic device provided in one embodiment of the related art; Figure 2 for Figure 1 A schematic diagram of the current distribution of the radiator in the antenna assembly of the wearable electronic device shown; Figure 3 for Figure 1 The diagram shows the electric field distribution of the radiator when the wearable electronic device is in a worn state. For ease of illustration, Figure 2 (a) in the image is in color. Figure 2 (b) in the middle is Figure 2 The grayscale image of (a) in the image; Figure 3 (a) in the image is in color. Figure 3 (b) in the middle is Figure 3 The image shown is a grayscale representation of (a). In related technologies, the wearable electronic device 1 includes an antenna assembly 10 and a wearable body 30. The wearable body 30 carries the antenna assembly 10. Specifically, the antenna assembly 10 is housed within the wearable body 30. The antenna assembly 10 includes a radiator 110 and a feed source S. In related technologies, the radiator 110 is ring-shaped and made of metal. Therefore, the radiator 110 is also referred to as a metal ring. The feed source S is electrically connected to the radiator 110 to excite the radiator 110 to support a target frequency band.

[0037] Depend on Figure 2 As can be seen, the feed source S excites the radiator 110 to generate a resonant current I0, which is distributed along the metal ring in the same direction. In the schematic diagram of this embodiment, the resonant current I0 is distributed in a clockwise direction.

[0038] Depend on Figure 3 As can be seen, when the wearable electronic device 1 in the related technology is worn on the target part of the user, the electric field near the feed source S and the surface of the target part (such as a finger) is a transverse electric field, and the transverse electric field is very strong. Since the material of the target part of the human body has high loss characteristics, the radiation performance of the antenna assembly 10 will be greatly degraded when the wearable electronic device 1 is worn on the target part of the user.

[0039] Please see Figure 4 , Figure 4 for Figure 1 The diagram shows a performance comparison of the antenna assembly in the wearable electronic device 1 under worn and free space conditions. For ease of illustration, Figure 4 (a) in the image is in color. Figure 4 (b) in the middle is Figure 4The grayscale image in (a) is shown. This simulation uses the wearable electronic device 1 as an example of a ring (also called a finger ring), and simulates the user's finger as the target part of the device. When the wearable electronic device 1 is in a wearing state, it is considered as a ring worn on the user's finger. The wearable electronic device 1 is in free space, also referred to as the unworn state of the wearable electronic device 1. In... Figure 4 In the graph, the horizontal axis represents frequency (GHz), and the vertical axis represents efficiency (dB). Curve ① ( Figure 4 The red solid line in the middle is Figure 1 The radiation efficiency curve of the wearable electronic device 1 in the related technology shown is in the wearing state; curve ② ( Figure 4 The red dashed line in the middle is Figure 1 The system efficiency curve of the wearable electronic device 1 in the related technology shown is in the wearing state; curve ③ ( Figure 4 The blue solid line in the middle is Figure 1 The radiation efficiency curve of the wearable electronic device 1 in free space shown in the related technology is shown; curve ④ ( Figure 4 (middle blue dashed line) is Figure 1 The system efficiency curve of the wearable electronic device 1 in the related technology is shown in free space. It can be seen that, compared to the wearable electronic device 1 in free space, the radiation efficiency of the wearable electronic device 1 in the related technology is poor when it is worn; and the system efficiency of the wearable electronic device 1 in the related technology is poor when it is worn, compared to the wearable electronic device 1 in free space. Figure 4 It is evident that the system efficiency of the wearable electronic device 1 in free space is approximately -3dB. However, when the wearable device is in a wearing state, the system efficiency is -15dB. Therefore, compared to the wearable device in a free state, the system efficiency of the wearable device in the related technology deteriorates when it is worn, and this also significantly worsens the communication experience between the wearable device and other devices.

[0040] The wearable electronic device 1 provided in the embodiments of this application will now be described in detail.

[0041] The wearable electronic device 1 can be, but is not limited to, a ring (or bracelet), bracelet, anklet, or necklace with communication function. The wearable electronic device 1 is worn on a target part of the user's body. For example, when the wearable electronic device 1 is a ring, the target part is the user's finger; that is, the wearable electronic device 1 can be worn on the user's finger. When the wearable electronic device 1 is a bracelet, the target part is the user's wrist; that is, the wearable electronic device 1 can be worn on the user's wrist. When the wearable electronic device 1 is an anklet, the target part is the user's ankle; that is, the wearable electronic device 1 can be worn on the user's ankle. When the wearable electronic device 1 is a necklace, the target part is the user's neck; that is, the wearable electronic device 1 can be worn on the user's neck. It is understood that the above examples are merely examples of possible products of the wearable electronic device 1 and should not be construed as limiting the wearable electronic device 1 provided in the embodiments of this application. In the following schematic diagrams of various embodiments, the wearable electronic device 1 is illustrated as a ring. It should be understood that this should not be construed as a limitation on the embodiments of this application.

[0042] Please see Figure 5 , Figure 6 , Figure 7 and Figure 8 , Figure 5 A perspective view of a wearable electronic device provided according to an embodiment of this application; Figure 6 for Figure 5 A three-dimensional schematic diagram of the radiator in the wearable electronic device shown; Figure 7 This is one embodiment of the present application. Figure 5 A schematic diagram of the cross-sectional structure of the wearable electronic device along line II; Figure 8 One implementation method Figure 7 The diagram shows the equivalent circuit of the wearable electronic device. Figure 5 Image (a) is a perspective view of a wearable electronic device provided in one embodiment of this application. Figure 5 (b) in the middle is Figure 5The diagram in (a) shows the wearable electronic device when worn on a target location. The wearable electronic device 1 includes an antenna assembly 10. The antenna assembly 10 includes a radiator 110 and a feed source S. The radiator 110 includes a first sub-radiator 111 and a second sub-radiator 112. The first sub-radiator 111 has a first free end 1111 and a second free end 1112. The first free end 1111 and the second free end 1112 form a first opening 111a. The first sub-radiator 111 also has a first feed point P1. The second sub-radiator 112 is stacked and spaced apart from the first sub-radiator 111. The second sub-radiator 112 has a third free end 1121 and a fourth free end 1122. The third free end 1121 and the fourth free end 1122 form a second opening 112a. The second sub-radiator 112 also has a second feed point P2. When the wearable electronic device 1 is worn on the target part of the user, the second sub-radiator 112 is closer to the target part 3 than the first sub-radiator 111. The feed source S is electrically connected to the first feed point P1 and the second feed point P2 to excite the first sub-radiator 111 and the second sub-radiator 112 of the radiator 110 to jointly support the target frequency band, and when the second sub-radiator 112 supports the target frequency band, the second sub-radiator 112 generates a vertical electric field.

[0043] The first sub-radiator 111 can be, but is not limited to, a metal radiator made of metal material, a printed circuit board (FPC) radiator, or a laser direct forming (LDS) radiator printed on a substrate.

[0044] In this embodiment, viewed from the side, the first sub-radiator 111 is arc-shaped or similarly arc-shaped. In this embodiment, the two ends of the first sub-radiator 111 along its length are a first free end 1111 and a second free end 1112, respectively. The first sub-radiator 111 is not closed; the first free end 1111 and the second free end 1112 form a first opening 111a. The first feed point P1 may be located at the first free end 1111, the second free end 1112, or other parts of the first sub-radiator 111. In the schematic diagram of this embodiment, the first feed point P1 is illustrated as being located at the first free end 1111; this should not be construed as a limitation of the embodiments described in this application.

[0045] The second sub-radiator 112 can be, but is not limited to, a metal radiator made of metal, a printed circuit board (FPC) radiator, or an LDS radiator printed on a bracket. The second sub-radiator 112 can be made of the same material as the first radiator 110, or it can be made of a different material than the first sub-radiator 111; this is not limited here.

[0046] In this embodiment, viewed from the side, the second sub-radiator 112 is arc-shaped or similarly arc-shaped. In this embodiment, the two ends of the second sub-radiator 112 along its length are a third free end 1121 and a fourth free end 1122, respectively. The second sub-radiator 112 is not closed; the third free end 1121 and the fourth free end 1122 form a second opening 112a. The second feed point P2 may be located at the third free end 1121, the fourth free end 1122, or other parts of the second sub-radiator 112. In the schematic diagram of this embodiment, the second feed point P2 is illustrated as being located at the third free end 1121; this should not be construed as a limitation of the embodiment of this application.

[0047] Please refer to the following: Figure 7 and Figure 9 , Figure 9 for Figure 7 The diagram illustrates the electric field distribution of the first and second sub-radiators of the antenna assembly when the wearable electronic device is in a worn state, supporting the target frequency band. (For illustrative purposes only.) Figure 9 (a) in the diagram is a color illustration. Figure 9 (b) in the middle is Figure 9The grayscale image is shown in (a). It can be seen that when the wearable electronic device 1 is worn on the user's target area, the second sub-radiator 112, supporting the target frequency band, excites the second sub-radiator 112 to generate a vertical electric field perpendicular to the surface of the target area. This vertical electric field excites the user's target area to generate radiation in the target frequency band, thus ensuring that the wearable electronic device 1 maintains superior performance even when worn. In other words, in the wearable electronic device 1 provided in this embodiment, when the wearable electronic device 1 is worn on the target area, the first sub-radiator 111 and the second sub-radiator 112 in the radiator 110 are the main radiators of the target frequency band. Since the second sub-radiator 112 is closer to the target area than the first sub-radiator 111, the vertical electric field generated by the second sub-radiator 112 can excite the target area, causing it to generate radiation in the target frequency band. Therefore, the wearable electronic device 1 maintains superior performance in the target frequency band even when worn. Specifically, when the second sub-radiator 112 supports the target frequency band, it generates a vertical electric field perpendicular to the surface of the target area. When the target area is a finger, the vertical electric field is perpendicular to the finger surface. The target area (e.g., a finger) is typically a mixture of fat, muscle, bone, and water, exhibiting characteristics of high dielectric constant, low conductivity, and high loss factor. The vertical electric field generated by the second sub-radiator 112 excites the target area. Due to the target area's high dielectric constant and other characteristics, the target area radiates under the excitation of the vertical electric field generated by the second sub-radiator 112. The radiation characteristics generated by the target area under the excitation of the vertical electric field generated by the second sub-radiator 112 are far superior to the loss effect, thus improving the radiation performance of the antenna assembly 10 in the target frequency band.

[0048] In summary, the wearable electronic device 1 provided in this application, through the design of the radiator 110 in the antenna assembly 10 of the wearable electronic device 1, includes a first sub-radiator 111 and a second sub-radiator 112 stacked and spaced apart. The first sub-radiator 111 has a first opening 111a, and the second sub-radiator 112 has a second opening 112a. The feed source S is electrically connected to a first feed point P1 of the first sub-radiator 111 and a second feed point P2 of the second sub-radiator 112 to excite the first sub-radiator 111 and the second sub-radiator 112 to jointly support the target frequency band, thereby realizing the communication function of the wearable electronic device 1 in the target frequency band. When the wearable electronic device 1 is worn on the user's target area, the second sub-radiator 112 is closer to the target area than the first sub-radiator 111. Furthermore, when the second sub-radiator 112 supports the target frequency band, it generates a vertical electric field that can excite the target area, causing it to radiate at the target frequency band. Therefore, when the wearable electronic device 1 is worn, it still has good communication performance at the target frequency band.

[0049] Furthermore, in one embodiment, when the first sub-radiator 111 supports the target frequency band, the first sub-radiator 111 also generates a vertical electric field, which is perpendicular to the surface of the target part. When the target part is a finger, the vertical electric field is perpendicular to the finger surface. The target part (such as a finger) is typically a mixture of fat, muscle, bone, and water, and has the characteristics of high dielectric constant, low conductivity, and high loss factor. The vertical electric field generated by the first sub-radiator 111 excites the target part. Because the target part has characteristics such as high dielectric constant, the target part radiates when excited by the vertical electric field generated by the first sub-radiator 111. The radiation characteristics generated by the target part excited by the vertical electric field generated by the first sub-radiator 111 are far superior to the loss effect. Therefore, the radiation performance of the antenna assembly 10 in the target frequency band can be improved.

[0050] Furthermore, in one embodiment, the half-wavelength dipole mode of the radiator 110 supports the target frequency band. Please refer to [further details omitted]. Figure 7 , Figure 10 , Figure 11 and Figure 12 , Figure 10 for Figure 7 A schematic diagram of the current distribution of the first and second sub-radiators of the antenna assembly of the wearable electronic device when supporting the target frequency band. Figure 11 for Figure 7The image shows the far-field radiation pattern of a wearable electronic device when it is in wear mode and supports the target frequency band. Figure 12 for Figure 7 The diagram shows a performance comparison of wearable electronic devices in worn and free-space states. For ease of illustration, Figure 10 (a) in the image is in color. Figure 10 (b) in the middle is Figure 10 The grayscale image of (a) in the image; Figure 11 (a) in the image is in color. Figure 11 (b) in the middle is Figure 11 The grayscale image of (a) in the image; Figure 12 (a) in the image is in color. Figure 12 (b) in the middle is Figure 12 The grayscale image is shown in (a) of the simulation diagram. This simulation uses the wearable electronic device 1 as an example of a ring (also called a finger ring), and the user's target part 3 as the finger. When the wearable electronic device 1 is in a wearing state, the ring is worn on the user's finger. Furthermore, please refer to... Figure 1 and Figure 11 The orientation of the front of the first sub-radiator 111 is denoted as D0. The wearable electronic device 1 is in free space, also referred to as the wearable electronic device 1 in an unworn state. Wherein, in Figure 12 In the graph, the horizontal axis represents frequency (GHz), and the vertical axis represents efficiency (dB). Curve ① ( Figure 12 The red solid line in the middle is Figure 7 The radiation efficiency curve of wearable electronic device 1 in the wearing state is shown; curve ② ( Figure 12 (The red dashed line in the middle) is Figure 7 The system efficiency curve of the wearable electronic device 1 in the wearing state is shown; curve ③ ( Figure 12 The blue solid line in the middle is Figure 7 The wearable electronic device 1 is shown with a radiation efficiency curve in free space; curve ④ ( Figure 12 The middle blue dashed line is Figure 7 The system efficiency curve of the wearable electronic device 1 in free space is shown.

[0051] Please refer to the following: Figure 7 and Figure 10 ,exist Figure 10In (a) of the diagram, red dots indicate strong current points, and blue dots indicate weak current points. When the first sub-radiator 111 supports the preset frequency band, a first resonant mode is generated, corresponding to a first resonant current I1. The weak current point of the first resonant current I1 is located at the first free end 1111 and the second free end 1112, while the strong current point of the first resonant current I1 is located at the midpoint of the first sub-radiator 111. Correspondingly, when the second sub-radiator 112 supports the preset frequency band, a second resonant mode is generated, corresponding to a second resonant current I2. The weak current point of the second resonant current I2 is located at the third free end 1121 and the fourth free end 1122, while the strong current point of the second resonant current I2 is located at the midpoint of the second sub-radiator 112. Furthermore, the current direction of the second resonant current I2 is opposite to that of the first resonant current I1. From the first resonant current I1 and the second resonant current I2, it can be seen that the first resonant mode is a half-wavelength mode, and the second resonant mode is also a half-wavelength mode. The first resonant current I1 is the current corresponding to the half-wavelength mode of the first sub-radiator 111, and the second resonant current I2 is the current corresponding to the half-wavelength mode of the second sub-radiator 112. That is, the half-wavelength modes of the first sub-radiator 111 and the second sub-radiator 112 together support the target frequency band. In other words, the half-wavelength dipole mode (also called the 1 / 2λ dipole mode) of the radiator 110 supports the target frequency band.

[0052] In the current half-wavelength period illustrated, the first resonant current I1 flows from the first free end 1111 to the second free end 1112, and the second resonant current I2 flows from the fourth free end 1122 to the third free end 1121. In other words, in the current half-wavelength period illustrated: the first resonant current I1 flows clockwise, and the second resonant current I2 flows counterclockwise. Understandably, both the first resonant current I1 and the second resonant current I2 are periodically changing. In the next half-wavelength period: the first resonant current I1 flows from the second free end 1112 to the first free end 1111, and the second resonant current I2 flows from the third free end 1121 to the fourth free end 1122.

[0053] Please refer to the following: Figure 7 and Figure 9The second sub-radiator 112 generates a vertical electric field perpendicular to the surface of the target area. When the target area is a finger, the vertical electric field is perpendicular to the finger surface. The target area (e.g., a finger) is typically a mixture of fat, muscle, bone, and water, exhibiting high dielectric constant, low conductivity, and high loss factor. The vertical electric field generated by the second sub-radiator 112 excites the target area. Due to the target area's high dielectric constant and other characteristics, the target area radiates under the excitation of the vertical electric field generated by the second sub-radiator 112. The radiation characteristics generated by the target area under the excitation of the vertical electric field generated by the second sub-radiator 112 are far superior to the loss effect, thus improving the radiation performance of the antenna assembly 10 in the target frequency band. The excitation electric field generated by the vertical electric field continuously rotates along the direction of the center of the target area. Therefore, the far-field radiation pattern generated by the target area is as follows: Figure 11 As shown, a radiation pattern similar to a magnetic dipole is generated. The strongest point of the far-field radiation pattern of the antenna assembly 10 is aligned with the positive direction of the axes of the first sub-radiator 111 and the second sub-radiator 112. This requires that, when the wearable electronic device 1 is worn, the front of the first sub-radiator 111 and the front of the second sub-radiator 112 should correspond to the front of the finger to avoid being blocked or touched by other fingers, so as to ensure the communication performance of the antenna assembly 10 in the target frequency band.

[0054] Please see Figure 12 , Figure 12 The diagram illustrates a comparison of the radiation performance of the wearable electronic device 1 in free space and in a worn state. The simulation uses the Bluetooth operating band (2.4GHz to 2.485GHz) as an example. It shows that when the wearable electronic device 1 is worn on the target area: in the target frequency band, the radiation efficiency increases by 0.9dB, the system efficiency increases by approximately 1.5dB, and the average system efficiency is approximately -8.8dB. Therefore, compared to the antenna performance of the wearable electronic device 1 in a free state, the antenna performance of the wearable electronic device 1 provided in this embodiment is improved when worn.

[0055] Therefore, the wearable electronic device 1 provided in this application, when the second sub-radiator 112 supports the target frequency band, generates a vertical electric field. When the wearable electronic device 1 is worn on a user's target area, the second sub-radiator 112 generates a vertical electric field, which can excite the target area, causing it to radiate the target frequency band. Thus, when the wearable electronic device 1 is in a wearing state, it still maintains good communication performance in the target frequency band. Furthermore, the half-wavelength dipole mode of the radiator 110 supports the target frequency band, ensuring that the wearable electronic device 1 is in a wearing state and that the radiator 110 has a good far-field radiation pattern when supporting the target frequency band, further enhancing the communication performance of the antenna assembly 10 in the target frequency band.

[0056] Please see Figure 13 , Figure 13 This is a schematic diagram of the electrical length of the first sub-radiator in one embodiment. The electrical length EL1 of the first sub-radiator 111 satisfies: 0.4λ≤EL1≤0.6λ, where λ is the wavelength corresponding to the center frequency point of the target frequency band.

[0057] The electrical length EL1 of the first sub-radiator 111 can be, but is not limited to, 0.4λ, 0.45λ, 0.5λ, 0.55λ, or 0.6λ. 0.4λ≤EL1≤0.6λ, that is, the electrical length EL1 of the first sub-radiator 111 satisfies: 0.5λ-0.1λ≤EL1≤0.5λ+0.1λ.

[0058] If the electrical length EL1 of the first sub-radiator 111 is small, the radiation performance of the first sub-radiator 111 when supporting the target frequency band will be low; while if the electrical length EL1 of the first sub-radiator 111 is large, the electrical length of the first sub-radiator 111 differs too much from the target frequency band supported by the first sub-radiator 111, and the length of the first sub-radiator 111 is large, which is not conducive to the miniaturization of the wearable electronic device 1, nor is it conducive to the layout of the first sub-radiator 111 in the wearable device.

[0059] In this embodiment, the electrical length EL1 of the first sub-radiator 111 satisfies: 0.4λ≤EL1≤0.6λ, which makes the electrical length of the first sub-radiator 111 more compatible with the first resonant mode supported by the first sub-radiator 111. This enables the first sub-radiator 111 to better support the target frequency band and has better radiation efficiency when supporting the target frequency band. In addition, it is also beneficial to the layout of the first sub-radiator 111 in the wearable device and to the miniaturization of the wearable device.

[0060] Please see Figure 14 , Figure 14 This is a schematic diagram of the electrical length of the second sub-radiator in one embodiment. The electrical length EL2 of the second sub-radiator 112 satisfies: 0.4λ≤EL2≤0.6λ, where λ is the wavelength corresponding to the center frequency point of the target frequency band.

[0061] The electrical length EL2 of the second sub-radiator 112 can be, but is not limited to, 0.4λ, 0.45λ, 0.5λ, 0.55λ, or 0.6λ. 0.4λ≤EL2≤0.6λ, that is, the electrical length EL2 of the second sub-radiator 112 satisfies: 0.5λ-0.1λ≤EL2≤0.5λ+0.1λ.

[0062] If the electrical length EL2 of the second sub-radiator 112 is small, the radiation performance of the second sub-radiator 112 when supporting the target frequency band will be low; while if the electrical length EL2 of the second sub-radiator 112 is large, the electrical length of the second sub-radiator 112 differs too much from the target frequency band supported by the second sub-radiator 112, and the length of the second sub-radiator 112 is large, which is not conducive to the miniaturization of the wearable electronic device 1, nor is it conducive to the layout of the second sub-radiator 112 in the wearable device.

[0063] In this embodiment, the electrical length EL2 of the second sub-radiator 112 satisfies: 0.4λ≤EL2≤0.6λ, which makes the electrical length of the second sub-radiator 112 more compatible with the first resonant mode supported by the second sub-radiator 112. This enables the second sub-radiator 112 to better support the target frequency band and has better radiation efficiency when supporting the target frequency band. In addition, it is also beneficial to the layout of the second sub-radiator 112 in the wearable device and to the miniaturization of the wearable device.

[0064] Furthermore, given a fixed length of the first sub-radiator 111, if the second sub-radiator 112 is longer, the antenna assembly 10 will generate an additional first parasitic resonance. This first parasitic resonance, with the second sub-radiator 112 as the main radiator 110, generates a transverse electric field. When the wearable electronic device 1 is worn on a user's target area, the electromagnetic wave signal corresponding to this transverse electric field will be absorbed by the target area, thereby affecting the efficiency of the target frequency band.

[0065] Furthermore, given a fixed length for the second sub-radiator 112, if the first sub-radiator 111 is longer, the antenna assembly 10 will generate an additional second parasitic resonance. This second parasitic resonance, with the first sub-radiator 111 as the main radiator 110, generates a transverse electric field. When the wearable electronic device 1 is worn on a user's target area, the electromagnetic wave signal corresponding to this transverse electric field will be absorbed by the target area, thereby affecting the efficiency of the target frequency band.

[0066] In this embodiment, the electrical length EL1 of the first sub-radiator 111 satisfies: 0.4λ≤EL1≤0.6λ, and the electrical length EL2 of the second sub-radiator 112 satisfies: 0.4λ≤EL2≤0.6λ. The electrical length of the second sub-radiator 112 is relatively close to that of the first sub-radiator 111, thereby enabling the target frequency band to have better efficiency.

[0067] Please see Figure 15 , Figure 15 Another implementation Figure 7 The diagram shows an equivalent circuit of the wearable electronic device. In this embodiment, the first feed point P1 is located at the first free end 1111, and the second feed point P2 is located at the third free end 1121. The antenna assembly 10 also includes a matching circuit M. The feed source S is electrically connected to the first feed point P1 through the matching circuit M, and the feed source S is electrically connected to the second feed point P2 through the matching circuit M.

[0068] The matching circuit M is also called a matching network. The first feed point P1 is located at the first free end 1111, thereby effectively exciting the first resonant mode of the first sub-radiator 111. Correspondingly, the second feed point P2 is located at the third free end 1121, thereby effectively exciting the second resonant mode of the second sub-radiator 112.

[0069] The matching circuit M is used for impedance matching between the feed S and the first sub-radiator 111, and is used to match the output impedance of the feed S with the input impedance of the first sub-radiator 111; correspondingly, the matching circuit M is used for impedance matching between the feed S and the second sub-radiator 112, and is used to match the output impedance of the feed S with the input impedance of the second sub-radiator 112; thereby enabling the antenna assembly 10 to have better antenna performance in the target frequency band.

[0070] Please refer to the following: Figure 16 , Figure 16 for Figure 8 A schematic diagram of the first and second sub-radiators in a wearable electronic device is provided. Figure 16 (b) is Figure 16 (a) is an enlarged schematic diagram at point II. The distance d between the first sub-radiator 111 and the second sub-radiator 112 in the stacking direction satisfies: 1.5mm ≤ d ≤ 10mm.

[0071] The distance d between the first sub-radiator 111 and the second sub-radiator 112 in the stacking direction can be, but is not limited to, 1.5 mm, or 2.0 mm, or 2.5 mm, or 3.0 mm, or 3.5 mm, or 4.0 mm, or 4.5 mm, or 5.0 mm, or 5.5 mm, or 6.0 mm, or 6.5 mm, or 7.0 mm, or 7.5 mm, or 8.0 mm, or 8.5 mm, or 9.0 mm, or 9.5 mm, or 10.0 mm.

[0072] When the distance d between the first sub-radiator 111 and the second sub-radiator 112 in the stacking direction is small, the efficiency of the first sub-radiator 111 and the second sub-radiator 112 in supporting the target frequency band is not high; when the distance d between the first sub-radiator 111 and the second sub-radiator 112 in the stacking direction is large, the efficiency of the first sub-radiator 111 and the second sub-radiator 112 in supporting the target frequency band is high, however, the wearable electronic device is large and bulky. In this embodiment, the distance d between the first sub-radiator 111 and the second sub-radiator 112 in the stacking direction satisfies: 1.5mm ≤ d ≤ 10mm. On the one hand, this allows the first sub-radiator 111 and the second sub-radiator 112 to have better radiation efficiency when supporting the target frequency band; on the other hand, it also takes into account the design requirements for miniaturization of the wearable device.

[0073] Please see Figure 17 , Figure 17 This is another embodiment of the present application. Figure 5A cross-sectional view of the wearable electronic device along line II is shown in the figure. In this embodiment, the wearable electronic device 1 further includes a motherboard 20. The motherboard 20 includes a carrier substrate 210 and a second sub-radiator 112, the second sub-radiator 112 being supported on the carrier substrate 210. The feed source S is disposed on the carrier substrate 210.

[0074] The motherboard 20 may also be referred to as the main circuit board. The carrier substrate 210 may include one or more insulating layers. The second sub-radiator 112 is supported on the carrier substrate 210, and may be, but is not limited to, disposed on the surface of the carrier substrate 210 near the first sub-radiator 111, disposed on the surface of the carrier substrate 210 away from the first sub-radiator 111, or embedded in the carrier substrate 210.

[0075] In this embodiment, the second sub-radiator 112 is supported on the carrier substrate 210 of the motherboard 20. Therefore, there is no need to set an additional support structure in the wearable electronic device to support the second sub-radiator 112, which is beneficial to the miniaturization of the wearable electronic device 1.

[0076] The feed source S is disposed on the carrier substrate 210. The feed source S can be electrically connected to the second feed point P2 of the second sub-radiator 112 through a transmission line disposed on the carrier substrate 210. The feed source S can be electrically connected to the first feed point P1 of the first sub-radiator 111 through a feed component (such as a conductive spring, conductive adhesive, or conductive screw).

[0077] When the antenna assembly 10 further includes a matching circuit M, the feed source S is electrically connected to the matching circuit M via a transmission line disposed on the carrier substrate 210, and the matching circuit M is electrically connected to the second feed point P2 of the second sub-radiator 112 via a transmission line disposed on the carrier substrate 210. The matching circuit M can be electrically connected to the first feed point P1 of the first sub-radiator 111 via a feed component (such as a conductive spring, conductive adhesive, or conductive screw).

[0078] Further, please refer to Figures 5 to 8 , Figure 17 As shown in the accompanying drawings, the wearable electronic device 1 further includes a wearable body 30. The wearable body 30 is used to carry the first sub-radiator 111 and the second sub-radiator 112, and the wearable body 30 is used to be worn on a target part of the user's body.

[0079] The wearable body 30, also known as an aesthetic accessory, can be made of insulating materials such as plastic or silicone, to avoid blocking electromagnetic wave signals in the target frequency band supported by the antenna assembly 10.

[0080] The wearable body 30 is used to carry the first sub-radiator 111 and the second sub-radiator 112. Normally, the first sub-radiator 111 and the second sub-radiator 112 are disposed inside the wearable body 30, but this is not the only option. When the first sub-radiator 111 and the second sub-radiator 112 are disposed inside the wearable body 30, the wearable body 30 serves to protect the first sub-radiator 111 and the second sub-radiator 112.

[0081] For further information, please refer to [link / reference]. Figures 5 to 8 ,as well as Figure 18 , Figure 18 A perspective view of a wearable electronic device provided for another embodiment of this application. Figure 18 and Figure 5 The difference in (a) is that, in Figure 18 The diagram shows the sign part 321. Figure 18 The cross-sectional view of the wearable electronic device 1 provided in the document can be referred to. Figures 6 to 8 The wearable body 30 has a wearing hole 310 for accommodating a target part of the user. The wearable body also has an inner wall surface 310a defining the wearing hole 310 and an outer surface 320a facing away from the inner wall surface 310a. The outer surface 320a has a marking portion 321 corresponding to the portion of the radiator 110; or the wearable electronic device 1 further includes a marking portion 321, which is disposed on the outer surface 320a of the wearable body corresponding to the wearing hole 310.

[0082] When the wearable electronic device 1 is worn on a user's target area, it can be fitted onto the target area, and the wearing hole 310 of the wearable body 30 accommodates the target area. The inner wall surface 310a of the wearable body 30 is closer to the target area than the outer surface 320a. When the wearable electronic device 1 is worn on the user's target area, the inner wall surface 310a can either fit snugly against the target area or have a gap with the target area; this is not limited here.

[0083] The outer surface 320a has a marking portion 321 corresponding to the radiator 110. For example, the marking portion 321 can be a pattern, text, or groove provided on the outer surface 320a. When the wearable electronic device 1 also includes the marking portion 321, the marking portion 321 can also be a gemstone or artificial gemstone.

[0084] The marking portion 321 is used to indicate the position of the radiator 110, so that when the wearable electronic device 1 is worn on the target part, it has better communication performance in the target frequency band. For example, when the wearable electronic device 1 is a ring, the marking portion 321 is provided on the outer surface 320a at the midpoint of the first sub-radiator 111 or at a position near the midpoint of the first sub-radiator 111. In this way, it can instruct the user to ensure that the front of the first sub-radiator 111 corresponds to the front of the finger when wearing the wearable electronic device 1, avoiding the first sub-radiator 111 and the second sub-radiator 112 being blocked by other fingers, thereby ensuring the communication performance of the antenna assembly 10 in the target frequency band.

[0085] Further, please refer to Figure 19 , Figure 19 In another embodiment of this application Figure 5 The diagram shows a cross-sectional view of the wearable electronic device along line II. In this embodiment, the wearable electronic device 1 further includes a detection sensor 40. The detection sensor 40 is disposed on the carrier substrate 210 and is used to detect the user's target parameters when the wearable electronic device 1 is worn on the user's target area.

[0086] The detection sensor 40 can be, but is not limited to, a blood pressure sensor or a pulse sensor. When the detection sensor 40 is a blood pressure sensor, the target parameter is blood pressure, and when the wearable electronic device 1 is worn on the target site, the detection sensor 40 can detect the user's blood pressure. When the detection sensor 40 is a pulse sensor, the target parameter is pulse. When the wearable electronic device 1 is worn on the target site, the detection sensor 40 can detect the user's pulse.

[0087] In this embodiment, the wearable electronic device 1 further includes a detection sensor 40, which is used to detect the user's target parameters when the wearable electronic device 1 is worn on the user's target part, thereby enabling the wearable device to integrate more functions.

[0088] Please refer to the following: Figure 20 , Figure 21 and Figure 22 , Figure 20 This is yet another embodiment of the present application. Figure 5 A schematic diagram of the cross-sectional structure of the wearable electronic device along line II; Figure 21 This is yet another embodiment of the present application. Figure 5 A schematic diagram of the cross-sectional structure of the wearable electronic device along line II; Figure 22 This is another embodiment of the present application. Figure 5 The diagram shows a cross-sectional view of the wearable electronic device along line II. The first free end 1111 and the third free end 1121 satisfy the following conditions: the first free end 1111 is flush with or protrudes from the third free end 1121, and when the first free end 1111 protrudes from the third free end 1121, the length D1 of the first free end 1111 protruding from the third free end 1121 satisfies: 0 < D1 ≤ 0.1λ; or, the third free end 1121 is flush with or protrudes from the first free end 1111, and when the third free end 1121 protrudes from the first free end 1111, the length D1' of the third free end 1121 protruding from the first free end 1111 satisfies: 0 < D1' ≤ 0.1λ. The second free end 1112 and the fourth free end 1122 satisfy the following conditions: the second free end 1112 is flush with or protrudes from the fourth free end 1122, and when the second free end 1112 protrudes from the fourth free end 1122, the length D2 of the second free end 1112 protruding from the fourth free end 1122 satisfies: 0 < D2 ≤ 0.1λ; or, the fourth free end 1122 is flush with or protrudes from the second free end 1112, and when the fourth free end 1122 protrudes from the second free end 1112, the length D2' of the fourth free end 1122 protruding from the second free end 1112 satisfies: 0 < D2' ≤ 0.1λ. Wherein, λ is the wavelength corresponding to the center frequency point of the target frequency band.

[0089] In the schematic diagram of this embodiment, in Figure 20 In this example, the first free end 1111 is flush with the third free end 1121, and the second free end 1112 is flush with the fourth free end 1122. Figure 21 In this illustration, the first free end 1111 protrudes from the third free end 1121, and therefore the fourth free end 1122 protrudes from the second free end 1112. Figure 22 In the illustration, the third free end 1121 protrudes from the first free end 1111, and the second free end 1112 protrudes from the fourth free end 1122. It should be understood that the content shown in the schematic diagrams of the embodiments of this application should not be construed as a limitation of the embodiments of this application.

[0090] In this embodiment, the above-mentioned relationship between the first free end 1111 and the third free end 1121, and the above-mentioned relationship between the second free end 1112 and the fourth free end 1122, makes it less likely for the wearable electronic device 1 to be blocked by other parts of the user when it is worn on the user's target part, thereby enabling the antenna assembly 10 of the wearable electronic device 1 to have better communication performance in the target frequency band.

[0091] The wearable electronic device 1 provided in any of the preceding embodiments includes a target frequency band including the Bluetooth frequency band, the GPS L1 frequency band, or the GPS L5 frequency band.

[0092] When the target frequency band includes the Bluetooth frequency band, the communication requirements of the wearable electronic device 1 in the Bluetooth frequency band can be met. When the target frequency band includes the GPS L1 frequency band, the communication requirements of the wearable electronic device 1 in the GPS L1 frequency band can be met. When the target frequency band includes the GPS L5 frequency band, the communication requirements of the wearable electronic device 1 in the GPS L5 frequency band can be met.

[0093] In summary, the wearable electronic device 1 provided by this application offers a wearable electronic device 1 based on the human body effect. Compared to when the wearable electronic device 1 is in free space, when the wearable electronic device 1 is worn on a target part of the user, the antenna assembly 10 has better antenna performance in the target frequency band.

[0094] When the antenna assembly 10 of the wearable electronic device 1 provided in this application supports the target frequency band, the first sub-radiator 111 and the second sub-radiator 112 are the main radiators. The vertical electric field generated by the second sub-radiator 112 is used to excite the target part of the user to radiate electromagnetic wave signals of the target frequency band, so that when the wearable electronic device 1 is in the wearing state of being worn to the target part, it still has superior antenna performance in the target frequency band.

[0095] Furthermore, in some embodiments, when the wearable electronic device 1 is worn on the target area: the antenna assembly 10 shows a 0.9 dB increase in radiation efficiency and an approximately 1.5 dB increase in system efficiency in the target frequency band, with an average system efficiency of approximately -8.8 dB. Therefore, compared to the antenna performance of the wearable electronic device 1 in its free state, the antenna performance of the wearable electronic device 1 provided in this application is superior when worn, enabling better communication with other auxiliary devices in the target frequency band and providing a better communication experience.

[0096] In one embodiment, in the radiator 110 of the antenna assembly 10 in the wearable electronic device 1, the second sub-radiator 112 is stacked and spaced apart from the first sub-radiator 111, and the second sub-radiator 112 is closer to the target location than the first sub-radiator 111. That is, the first sub-radiator 111 and the second sub-radiator 112 cannot be located in the same plane, thereby avoiding the generation of a strong transverse electric field. Furthermore, in one embodiment, the size of the first sub-radiator 111 is designed such that the electrical length EL1 of the first sub-radiator 111 satisfies: 0.4λ≤EL1≤0.6λ, where λ is the wavelength corresponding to the center frequency point of the target frequency band, thereby enabling the first sub-radiator 111 to have better radiation performance when supporting the target frequency band.

[0097] Furthermore, in one embodiment, the dimensions of the second sub-radiator 112 are designed such that its electrical length EL2 satisfies: 0.4λ ≤ EL2 ≤ 0.6λ, where λ is the wavelength corresponding to the center frequency of the target frequency band. This design ensures that the electrical length of the second sub-radiator 112 is well-matched to the first resonant mode it supports, enabling the second sub-radiator 112 to better support the target frequency band and achieve good radiation efficiency. Additionally, it avoids the possibility of poor antenna performance in free space at the target frequency band due to an excessively small size of the second sub-radiator 112.

[0098] Furthermore, the second sub-radiator 112 has a second opening 112a, meaning that the second sub-radiator 112 cannot be a closed conductive ring (such as a metal ring). If the second sub-radiator 112 is a closed conductive ring instead of an opening, when the wearable electronic device 1 is worn on the user's target area, the electric field distribution of the second sub-radiator 112 on the user's target area will be disrupted, resulting in a deterioration in radiation performance compared to free space, for example, a performance drop of 5 dB.

[0099] The above description represents some embodiments of this application. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.
