[0052] Wearable electronic devices generally require built-in antennas so that they can have positioning functions. Current wearable electronic devices have multiple built-in antennas, which enable them to receive satellite positioning signals of multiple frequencies. However, the internal space of wearable electronic devices is small, and it is difficult to set up multiple antennas.

[0053] Based on the above problems, the present application provides an antenna structure. Figure 1 As shown, the antenna structure includes a first arc-shaped radiator 100 and a frequency modulation component 200. The first end F of the first arc-shaped radiator 100 is used to be electrically connected to the position determination element 300, and the second end G of the first arc-shaped radiator 100 is used to be grounded. The first arc-shaped radiator 100 is used to receive a first frequency signal and a second frequency signal. The frequency modulation component 200 is electrically connected to the first arc-shaped radiator 100, and the frequency modulation component 200 is used to adjust the frequency of the first frequency signal to the first target frequency and adjust the frequency of the second frequency signal to the second target frequency. The first frequency signal includes a first satellite positioning signal, and the second frequency signal includes a second satellite positioning signal.

[0054] Specifically, the first end F of the first arc-shaped radiator 100 is used to be electrically connected to the position determination element 300, and the second end G of the first arc-shaped radiator 100 is used to be grounded, that is, the first end F of the first arc-shaped radiator 100 is a feeding point, and the second end G of the first arc-shaped radiator 100 is a grounding point. When the first arc-shaped radiator 100 is not connected to the frequency modulation component 200, the first arc-shaped radiator 100 can receive a first frequency signal and a second frequency signal, and the frequency of the second frequency signal is an integer multiple of the frequency of the first frequency signal.

[0055] The frequency modulation component 200 is electrically connected to the first arc-shaped radiator 100. The frequency modulation component 200 can adjust the frequency of the signal received by the first arc-shaped radiator 100, adjust the frequency of the first frequency signal to the first target frequency, and adjust the frequency of the second frequency signal to the second target frequency. The first frequency signal includes a first satellite positioning signal, and the second frequency signal includes a second satellite positioning signal. Finally, the antenna structure can receive the first satellite positioning signal of the first target frequency and the second satellite positioning signal of the second target frequency. Compared with using two radiators to receive two satellite positioning signals, the antenna structure provided in the embodiment of the present application can receive the first satellite positioning signal and the second satellite positioning signal using only the first arc-shaped radiator 100, which can reduce the length of the radiator, thereby reducing the space occupied by the antenna structure, which is conducive to the flexibility of the design of the antenna structure in wearable electronic devices.

[0056] In some embodiments, Figure 2 As shown, the frequency modulation component 200 is connected to a first preset position on the first arc-shaped radiator 100. The first preset position includes one or more of the following positions: the intersection position of the current strong area when the first arc-shaped radiator 100 receives the first frequency signal and the current weak area when the first arc-shaped radiator 100 receives the second frequency signal on the first arc-shaped radiator 100 ( Figure 2 The intersection position of the weak current area when the first arc-shaped radiator 100 receives the first frequency signal and the strong current area when the first arc-shaped radiator 100 receives the second frequency signal on the first arc-shaped radiator 100 ( Figure 2 The intersection position of the weak current area when the first arc-shaped radiator receives the first frequency signal and the weak current area when the first arc-shaped radiator receives the second frequency signal on the first arc-shaped radiator ( Figure 2 not shown).

[0057] Specifically, Figure 2 (a) is a schematic diagram of the current distribution on the first arc-shaped radiator 100 when the first arc-shaped radiator 100 receives the first frequency signal, wherein the reverse direction of the arrow represents the direction of the current, and the density of the arrows represents the strength of the current. The denser the arrows, the greater the current, and the sparser the arrows, the smaller the current. When the first arc-shaped radiator 100 receives the first frequency signal, a current will be generated on the first arc-shaped radiator 100. The area with a strong current on the first arc-shaped radiator 100 is called a strong current area, that is, Figure 2 The area with relatively dense arrows in (a) is referred to as the weak current area on the first arc-shaped radiator 100, that is, Figure 2The area with relatively sparse arrows in (a). If the frequency modulation component 200 is connected to the strong current area where the first arc-shaped radiator 100 receives the first frequency signal, the frequency modulation component 200 has little effect on the resonant frequency of the first arc-shaped radiator 100, that is, the frequency modulation component 200 causes a small change in the frequency of the first frequency signal. If the frequency modulation component 200 is connected to the weak current area where the first arc-shaped radiator 100 receives the first frequency signal, the frequency modulation component 200 has a greater effect on the resonant frequency of the first arc-shaped radiator 100, that is, the frequency modulation component 200 causes a greater change in the frequency of the first frequency signal.

[0058] Figure 2 (b) is a schematic diagram of the current distribution on the first arc-shaped radiator 100 when the first arc-shaped radiator 100 receives the second frequency signal, wherein the reverse direction of the arrow represents the direction of the current, and the density of the arrows represents the strength of the current. The denser the arrows, the greater the current, and the sparser the arrows, the smaller the current. When the first arc-shaped radiator 100 receives the second frequency signal, a current will be generated on the first arc-shaped radiator 100. The area with a strong current on the first arc-shaped radiator 100 is called a strong current area, that is, Figure 2 The area with relatively dense arrows in (b) is referred to as the weak current area on the first arc-shaped radiator 100, that is, Figure 2 The area with relatively sparse arrows in (b) of FIG. 1 . If the frequency modulation component 200 is connected to the strong current area where the first arc-shaped radiator 100 receives the second frequency signal, the frequency modulation component 200 has little effect on the resonant frequency of the first arc-shaped radiator 100, that is, the frequency modulation component 200 causes a small change in the frequency of the second frequency signal. If the frequency modulation component 200 is connected to the weak current area where the first arc-shaped radiator 100 receives the second frequency signal, the frequency modulation component 200 has a greater effect on the resonant frequency of the first arc-shaped radiator 100, that is, the frequency modulation component 200 causes a greater change in the frequency of the second frequency signal.

[0059] If the frequency modulation component 200 is connected to the intersection of the current strong area when the first arc-shaped radiator 100 receives the first frequency signal and the current weak area when the first arc-shaped radiator 100 receives the second frequency signal on the first arc-shaped radiator 100 (area A or area C on the first arc-shaped radiator 100), the frequency modulation component 200 can cause a small change in the frequency of the first frequency signal and a large change in the frequency of the second frequency signal.

[0060] If the frequency modulation component 200 is connected to the intersection of the weak current area when the first arc-shaped radiator 100 receives the first frequency signal and the strong current area when the first arc-shaped radiator 100 receives the second frequency signal on the first arc-shaped radiator 100 (area B on the first arc-shaped radiator 100), the frequency modulation component 200 can cause a larger change in the frequency of the first frequency signal and a smaller change in the frequency of the second frequency signal.

[0061] The frequency modulation component 200 is connected to the first preset position on the first arc-shaped radiator 100, and the frequencies of the first frequency signal and the second frequency signal can be adjusted, and the frequency of the first frequency signal is adjusted to the first target frequency, and the frequency of the second frequency signal is adjusted to the second target frequency, so that the antenna structure can finally receive the first satellite positioning signal of the first target frequency and the second satellite positioning signal of the second target frequency. Compared with the traditional method of using two radiators to receive two satellite positioning signals, the antenna structure provided in the embodiment of the present application uses a first arc-shaped radiator 100 to receive the first satellite positioning signal of the first target frequency and the second satellite positioning signal of the second target frequency, which can reduce the length of the radiator, facilitate the miniaturized design of the antenna structure, improve the flexible design of the antenna structure in wearable electronic devices, and reduce the design difficulty of the antenna structure.

[0062] It should be noted that Figure 2 Only some positions in the first preset position are shown, and the first arc-shaped radiator 100 receives a first frequency signal and a second frequency signal of different frequencies, and the first arc-shaped radiator 100 includes different first preset positions.

[0063] In some embodiments, the frequency modulation component 200 includes a capacitor and / or an inductor. When the frequency modulation component 200 includes a capacitor, the first end of the capacitor is connected to a first preset position on the first arc-shaped radiator 100, and the second end of the capacitor is used for grounding; when the frequency modulation component 200 includes an inductor, the first end of the inductor is connected to the first preset position on the first arc-shaped radiator 100, and the second end of the inductor is used for grounding.

[0064] Specifically, when a capacitor is connected in parallel to the first arc-shaped radiator 100, the frequency of the signal received by the first arc-shaped radiator 100 is reduced, that is, the frequencies of the first frequency signal and the second frequency signal received by the first arc-shaped radiator 100 are reduced. When an inductor is connected in parallel to the first arc-shaped radiator 100, the frequency of the signal received by the first arc-shaped radiator 100 is increased, that is, the frequencies of the first frequency signal and the second frequency signal received by the first arc-shaped radiator 100 are increased.

[0065] When the first end of the capacitor is connected to the intersection of the current strong area when the first arc-shaped radiator 100 receives the first frequency signal and the current weak area when the first arc-shaped radiator 100 receives the second frequency signal on the first arc-shaped radiator 100, that is, the first end of the capacitor is connected to the A area or the C area on the first arc-shaped radiator 100, and the second end of the capacitor is grounded, the frequency reduction amplitude of the first frequency signal is small, and the frequency reduction amplitude of the second frequency signal is large. When the first end of the inductor is connected to the intersection of the current strong area when the first arc-shaped radiator 100 receives the first frequency signal and the current weak area when the first arc-shaped radiator 100 receives the second frequency signal on the first arc-shaped radiator 100, that is, the first end of the inductor is connected to the A area or the C area on the first arc-shaped radiator 100, and the second end of the inductor is grounded, the frequency increase amplitude of the first frequency signal is small, and the frequency increase amplitude of the second frequency signal is large.

[0066] When the first end of the capacitor is connected to the intersection of the weak current area when the first arc-shaped radiator 100 receives the first frequency signal and the strong current area when the first arc-shaped radiator 100 receives the second frequency signal on the first arc-shaped radiator 100, that is, the first end of the capacitor is connected to the B area on the first arc-shaped radiator 100, and the second end of the capacitor is grounded, the frequency reduction amplitude of the first frequency signal is large, and the frequency reduction amplitude of the second frequency signal is small. When the first end of the inductor is connected to the intersection of the weak current area when the first arc-shaped radiator 100 receives the first frequency signal and the strong current area when the first arc-shaped radiator 100 receives the second frequency signal on the first arc-shaped radiator 100, that is, the first end of the inductor is connected to the B area on the first arc-shaped radiator 100, and the second end of the inductor is grounded, the frequency increase amplitude of the first frequency signal is large, and the frequency increase amplitude of the second frequency signal is small.

[0067] By connecting a capacitor or an inductor in parallel at a first preset position on the first arc-shaped radiator 100, the frequencies of the first frequency signal and the second frequency signal can be adjusted, and ultimately the first arc-shaped radiator 100 can receive a first satellite positioning signal of a first target frequency and a second satellite positioning signal of a second target frequency.

[0068] In some embodiments, Figure 3 As shown, the frequency modulation component 200 is connected to the second preset position of the first arc-shaped radiator 100. The second preset position includes the midpoint position of the first arc-shaped radiator 100 ( Figure 3 ), and / or, the second preset position includes two trisection points ( Figure 3 The position of at least one point among the point D position and the point H position).

[0069] Specifically, the midpoint position A of the first arc-shaped radiator 100 is the intersection position of the current weak area when the first arc-shaped radiator 100 receives the first frequency signal and the current strong area when the first arc-shaped radiator 100 receives the second frequency signal on the first arc-shaped radiator 100. When the frequency modulation component 200 is connected to the midpoint position of the first arc-shaped radiator 100, the frequency modulation component 200 can adjust the frequency of the first frequency signal to a greater extent and adjust the frequency of the second frequency signal to a lesser extent.

[0070] There are two trisection points on the first arc-shaped radiator 100, and the two trisection points ( Figure 3 Point D and point H in the figure are both the intersection of a strong current area when the first arc-shaped radiator 100 receives a first frequency signal and a weak current area when the first arc-shaped radiator 100 receives a second frequency signal on the first arc-shaped radiator 100. When the frequency modulation component 200 is connected to the three-division point, the frequency modulation component 200 can adjust the frequency of the first frequency signal by a smaller amplitude and adjust the frequency of the second frequency signal by a larger amplitude.

[0071] Thus, by connecting the frequency modulation component 200 to the midpoint position and / or the trisection point position of the first arc-shaped radiator 100, it is possible to adjust the frequency of the first frequency signal and the frequency of the second frequency signal received by the first arc-shaped radiator 100, adjust the frequency of the first frequency signal to the first target frequency, and adjust the frequency of the second frequency signal to the second target frequency, so that the antenna structure can finally receive the first satellite positioning signal of the first target frequency and the second satellite positioning signal of the second target frequency. Compared with the traditional method of using two radiators to receive two satellite positioning signals, the antenna structure provided in the embodiment of the present application uses a first arc-shaped radiator 100 to receive the first satellite positioning signal of the first target frequency and the second satellite positioning signal of the second target frequency, which can reduce the length of the radiator, facilitate the miniaturized design of the antenna structure, improve the flexible design of the antenna structure in wearable electronic devices, and reduce the design difficulty of the antenna structure.

[0072] Exemplarily, the first satellite positioning signal is an L1 frequency band signal, and the second satellite positioning signal is an L5 frequency band signal.

[0073] In some embodiments, Figure 4 As shown, the first arc-shaped radiator 100 is further used to receive a third frequency signal, and the frequency modulation component 200 is further used to adjust the frequency of the third frequency signal to a third target frequency.

[0074] Specifically, when the first arc-shaped radiator 100 is not connected to the frequency modulation component 200, the first arc-shaped radiator 100 can receive a third frequency signal in addition to the first frequency signal and the second frequency signal. The frequency of the third frequency signal is an integer multiple of the frequency of the first frequency signal, and the frequency of the third frequency signal is different from the frequency of the second frequency signal.

[0075] Figure 4 (c) is a schematic diagram of the current distribution on the first arc-shaped radiator 100 when the first arc-shaped radiator 100 receives the third frequency signal, wherein the reverse direction of the arrow represents the direction of the current, and the density of the arrows represents the strength of the current. The denser the arrows, the greater the current, and the sparser the arrows, the smaller the current. When the first arc-shaped radiator 100 receives the third frequency signal, a current will be generated on the first arc-shaped radiator 100. The area with a strong current on the first arc-shaped radiator 100 is called a strong current area, that is, Figure 4 The area with relatively dense arrows in (c) is referred to as the weak current area on the first arc-shaped radiator 100, that is, Figure 4 The area with relatively sparse arrows in (c) of FIG. 1 . If the frequency modulation component 200 is connected to the strong current area where the first arc-shaped radiator 100 receives the third frequency signal, the frequency modulation component 200 has little effect on the resonant frequency of the first arc-shaped radiator 100, that is, the frequency modulation component 200 causes a small change in the frequency of the third frequency signal. If the frequency modulation component 200 is connected to the weak current area where the first arc-shaped radiator 100 receives the third frequency signal, the frequency modulation component 200 has a greater effect on the resonant frequency of the first arc-shaped radiator 100, that is, the frequency modulation component 200 causes a greater change in the frequency of the third frequency signal.

[0076] The frequency modulation component 200 is electrically connected to the first arc-shaped radiator 100, and the frequency modulation component 200 can adjust the frequency of the signal received by the first arc-shaped radiator 100, adjust the frequency of the first frequency signal to the first target frequency, adjust the frequency of the second frequency signal to the second target frequency, and adjust the frequency of the third frequency signal to the third target frequency. The first frequency signal includes a first satellite positioning signal, and the second frequency signal includes a second satellite positioning signal. Finally, the antenna structure can receive the first satellite positioning signal of the first target frequency, the second satellite positioning signal of the second target frequency, and the third frequency signal. Compared with using three radiators to receive three frequency signals, the antenna structure provided in the embodiment of the present application only uses the first arc-shaped radiator 100 to receive the first satellite positioning signal, the second satellite positioning signal, and the third frequency signal, which can reduce the length of the radiator, thereby reducing the occupied space of the antenna structure, which is conducive to the flexibility of the antenna structure in the design of wearable electronic devices.

[0077] In some embodiments, Figure 4As shown, the frequency modulation component 200 is connected to the third preset position on the first arc-shaped radiator 100. The third preset position includes one or more of the following positions: the intersection of the current strong area when the first arc-shaped radiator 100 receives the first frequency signal, the current strong area when the first arc-shaped radiator 100 receives the second frequency signal, and the current weak area when the first arc-shaped radiator 100 receives the third frequency signal on the first arc-shaped radiator 100 ( Figure 4 The intersection position of the current strong area when the first arc-shaped radiator 100 receives the first frequency signal, the current weak area when the first arc-shaped radiator 100 receives the second frequency signal, and the current strong area when the first arc-shaped radiator 100 receives the third frequency signal on the first arc-shaped radiator 100 ( Figure 4 The intersection position of the strong current area when the first arc-shaped radiator 100 receives the first frequency signal, the weak current area when the first arc-shaped radiator 100 receives the second frequency signal, and the weak current area when the first arc-shaped radiator 100 receives the third frequency signal on the first arc-shaped radiator 100 ( Figure 4 The intersection position of the weak current area when the first arc-shaped radiator 100 receives the first frequency signal, the strong current area when the first arc-shaped radiator 100 receives the second frequency signal, and the strong current area when the first arc-shaped radiator 100 receives the third frequency signal on the first arc-shaped radiator 100 ( Figure 4 The intersection position of the weak current area when the first arc-shaped radiator 100 receives the first frequency signal, the strong current area when the first arc-shaped radiator 100 receives the second frequency signal, and the weak current area when the first arc-shaped radiator 100 receives the third frequency signal on the first arc-shaped radiator 100 ( Figure 4 The intersection position of the weak current area when the first arc-shaped radiator 100 receives the first frequency signal, the weak current area when the first arc-shaped radiator 100 receives the second frequency signal, and the strong current area when the first arc-shaped radiator 100 receives the third frequency signal on the first arc-shaped radiator 100 ( Figure 4 The intersection position of the weak current zone when the first arc-shaped radiator 100 receives the first frequency signal, the weak current zone when the first arc-shaped radiator 100 receives the second frequency signal, and the weak current zone when the first arc-shaped radiator 100 receives the third frequency signal on the first arc-shaped radiator 100 ( Figure 4 not shown).

[0078] Specifically, when the first arc-shaped radiator 100 receives the first frequency signal, a current will be generated on the first arc-shaped radiator 100. The area on the first arc-shaped radiator 100 where the current is relatively strong is referred to as a strong current area, and the area on the first arc-shaped radiator 100 where the current is relatively weak is referred to as a weak current area. If the frequency modulation component 200 is connected to the strong current area where the first arc-shaped radiator 100 receives the first frequency signal, the frequency modulation component 200 has a small effect on the resonant frequency of the first arc-shaped radiator 100, that is, the frequency modulation component 200 will cause a small change in the frequency of the first frequency signal. If the frequency modulation component 200 is connected to the weak current area where the first arc-shaped radiator 100 receives the first frequency signal, the frequency modulation component 200 has a large effect on the resonant frequency of the first arc-shaped radiator 100, that is, the frequency modulation component 200 will cause a large change in the frequency of the first frequency signal.

[0079] When the first arc-shaped radiator 100 receives the second frequency signal, a current will be generated on the first arc-shaped radiator 100. The area with a strong current on the first arc-shaped radiator 100 is called a strong current area, and the area with a weak current on the first arc-shaped radiator 100 is called a weak current area.

[0082] If the frequency modulation component 200 is connected to the intersection of the current strong area when the first arc-shaped radiator 100 receives the first frequency signal, the current weak area when the first arc-shaped radiator 100 receives the second frequency signal, and the current strong area when the first arc-shaped radiator 100 receives the third frequency signal on the first arc-shaped radiator 100 ( Figure 4 ), the frequency modulation component 200 can make the frequency of the first frequency signal change slightly, make the frequency of the second frequency signal change significantly, and make the frequency of the third frequency signal change slightly.

[0084] If the frequency modulation component 200 is connected to the intersection of the weak current area when the first arc-shaped radiator 100 receives the first frequency signal, the strong current area when the first arc-shaped radiator 100 receives the second frequency signal, and the strong current area when the first arc-shaped radiator 100 receives the third frequency signal on the first arc-shaped radiator 100 ( Figure 4 ), the frequency modulation component 200 can make the frequency of the first frequency signal change greatly, make the frequency of the second frequency signal change slightly, and make the frequency of the third frequency signal change slightly.

[0085] If the frequency modulation component 200 is connected to the intersection of the weak current area when the first arc-shaped radiator 100 receives the first frequency signal, the strong current area when the first arc-shaped radiator 100 receives the second frequency signal, and the weak current area when the first arc-shaped radiator 100 receives the third frequency signal on the first arc-shaped radiator 100 ( Figure 4When the frequency modulation component 200 is in the M3 region in the image, the frequency modulation component 200 can make the frequency of the first frequency signal change greatly, make the frequency of the second frequency signal change slightly, and make the frequency of the third frequency signal change greatly.

[0088] The frequency modulation component 200 is connected to the third preset position on the first arc-shaped radiator 100, and the frequencies of the first frequency signal, the second frequency signal, and the third frequency signal can be adjusted, and the frequency of the first frequency signal is adjusted to the first target frequency, the frequency of the second frequency signal is adjusted to the second target frequency, and the frequency of the third frequency signal is adjusted to the third target frequency. Finally, the antenna structure can receive the first satellite positioning signal of the first target frequency, the second satellite positioning signal of the second target frequency, and the third frequency signal of the third target frequency. Compared with using three radiators to receive three frequency signals, the antenna structure provided in the embodiment of the present application only uses the first arc-shaped radiator 100 to receive the first satellite positioning signal, the second satellite positioning signal, and the third frequency signal, which can reduce the length of the radiator, thereby reducing the occupied space of the antenna structure, which is conducive to the flexibility of the design of the antenna structure in wearable electronic devices.

[0089] It should be noted that Figure 4 Only some positions in the third preset position are given, and the first arc-shaped radiator 100 receives a first frequency signal, a second frequency signal and a third frequency signal of different frequencies, and the first arc-shaped radiator 100 includes different third preset positions.

[0090] Exemplarily, the first satellite positioning signal is an L1 frequency band signal, the second satellite positioning signal is an L5 frequency band signal, and the third frequency signal includes a WIFI / BT signal.

[0091] In some embodiments, Figure 5 As shown, the antenna structure further includes a second arc-shaped radiator 400. The first arc-shaped radiator 100 and the second arc-shaped radiator 400 form a complete ring. The second arc-shaped radiator 400 is used to receive a fourth frequency signal.

[0092] Specifically, the antenna structure also includes a second arc-shaped radiator 400, and the first arc-shaped radiator 100 and the second arc-shaped radiator 400 form a complete loop. The first arc-shaped radiator 100 can receive a first frequency signal, a second frequency signal and a third frequency signal. For the specific principle, see the above description. The second arc-shaped radiator 400 can receive a fourth frequency signal. In this way, the first arc-shaped radiator 100 and the second arc-shaped radiator 400 form a complete loop that can simultaneously receive signals of four frequencies (first frequency signal, second frequency signal, third frequency signal and fourth frequency signal). Compared with the traditional method that requires four radiators to receive signals of four frequencies, the antenna structure provided in the embodiment of the present application only uses one complete loop radiator to receive signals of four frequencies, which can greatly reduce the length of the radiator, thereby reducing the space occupied by the antenna structure, which is conducive to the flexibility of the antenna structure in the design of wearable electronic devices.

[0094] Specifically, the antenna structure can receive the first satellite positioning signal and the second satellite positioning signal, and transmit the first satellite positioning signal and the second satellite positioning signal to the position determination element. The position determination element is used to receive the first satellite positioning signal and the second satellite positioning signal from the antenna structure, and determine the current geographic location based on the first satellite positioning signal and the second satellite positioning signal. Since the antenna structure used in the wearable electronic device of the embodiment of the present application has the characteristics of small size and small space occupation, the antenna structure can be flexibly designed in the wearable electronic device, reducing the design difficulty of the antenna structure on the wearable electronic device.
