[0034] As can be seen from the above embodiments, the radiation pattern shaping of the first and second frame radiators of this disclosure can enhance the gain of the first frame radiator and improve the radiation intensity of the first frame radiator through the radiation pattern of the second frame radiator.

[0041] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings.

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.

[0043] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information.

[0044] Figure 1 This is a schematic diagram illustrating an antenna structure according to an exemplary embodiment, such as... Figure 1 As shown, the antenna structure includes a first frame radiator 1 and a second frame radiator 2. The first frame radiator 1 can radiate satellite frequency band signals and cellular frequency band signals. The satellite frequency band signals can include Tiantong frequency band signals or Beidou frequency band signals, and the cellular frequency band signals are mid-to-high frequency band signals. By utilizing the relatively close frequencies of the mid-to-high frequency band signals and the satellite frequency band signals, the satellite frequency band signals and the mid-to-high frequency band signals are combined on the first frame radiator 1, which is beneficial for a compact antenna structure. The second frame radiator 2 can be used to radiate cellular frequency band signals, and both the second frame radiator 2 and the first frame radiator 1 can be used to radiate at least one signal in the same frequency band. For example, both the first frame radiator 1 and the second frame radiator 2 can be used to radiate the B40 frequency band.

[0045] Still with Figure 1As shown, the first frame radiator 1 and the second frame radiator 2 are arranged at intervals along a first direction, and the projections of the first frame radiator 1 and the second frame radiator 2 at least partially overlap in this first direction. For example... Figure 1 As shown, the first frame radiator 1 and the second frame radiator 2 are arranged at intervals along the vertical direction, and their projections at least partially overlap in the vertical direction. When the first frame radiator 1 operates in a satellite frequency band, the radiation patterns of the first frame radiator 1 and the second frame radiator 2 point in the same direction. Therefore, the gain of the first frame radiator 1 can be enhanced by the radiation pattern of the second frame radiator 2, thereby improving its radiation coverage and intensity. Furthermore, since the first frame radiator 1 operates in a satellite frequency band, it means that the first frame radiator 1 does not need to operate in a cellular frequency band. Since the first frame radiator 1 and the second frame radiator 2 radiate the same frequency band, the second frame radiator 2 also does not need to operate in a cellular frequency band. Therefore, adjusting the radiation pattern of the second frame radiator 2 will not affect its own performance in covering the frequency band signal.

[0046] Of course, it is understandable that when the antenna structure is configured in an electronic device, in order to facilitate satellite communication, the first frame radiator 1 can form part of the top frame of the electronic device, and the second frame radiator 2 forms part of the bottom frame of the electronic device. Therefore, under normal conditions, such as Figure 1 As shown, the radiation pattern of the first frame radiator 1 faces the top of the electronic device, i.e., towards the zenith, while the radiation pattern of the second frame radiator 2 faces the bottom of the electronic device, i.e., towards the floor. There is a 180° phase difference between the radiation patterns of the first frame radiator 1 and the second frame radiator 2. Therefore, through circuit design, when the first frame radiator 1 operates in the satellite frequency band, the equivalent impedance of one port of the first frame radiator 1 and the second frame radiator 2 can be made to have inductive characteristics, while the equivalent impedance of the other port can have capacitive characteristics. This achieves equal-amplitude and in-phase feeding of the first frame radiator 1 and the second frame radiator 2, ensuring that the radiation patterns of both the first frame radiator 1 and the second frame radiator 2 face the zenith. Therefore, as... Figure 2 As shown, the gain of the first frame radiator 1 can be increased by shaping the radiation pattern of the first frame radiator 1 with the radiation pattern of the second frame radiator 2.

[0047] Furthermore, in order to achieve equal amplitude and in-phase feeding of the first frame radiator 1 and the second frame radiator 2 when the first frame radiator 1 is operating in the satellite frequency band, such as Figure 3As shown, the antenna structure also includes a first feed 3, a second feed 4, a first switching assembly 5, and a second switching assembly 6. The first feed 3 is electrically connected to the first frame radiator 1, and the second feed 4 is electrically connected to the second frame radiator 2. One end of the first switching assembly 5 is grounded, and the other end is electrically connected between the first frame radiator 1 and the first feed 3. One end of the second frame radiator 2 is grounded, and the other end is electrically connected between the second frame radiator 2 and the second feed 4. When the first frame radiator 1 operates in the satellite frequency band, the first switching assembly 5 is grounded via a capacitor, and the second switching assembly 6 is grounded via an inductor. Alternatively, in other embodiments, the first switching assembly 5 may be grounded via an inductor, and the second switching assembly 6 may be grounded via a capacitor. This achieves equal-amplitude and in-phase feeding of the first frame radiator 1 and the second frame radiator 2.

[0048] It should be noted that while the first switching component 5 may also include other switching states to achieve frequency band switching of the first frame radiator 1, similarly, the second switching component 6 may also include other switching states to achieve frequency band switching of the second frame radiator 2. Furthermore, other matching circuits are provided between the first frame radiator 1 and the first feed 3 for impedance matching, and other matching circuits may also be provided between the second frame radiator 2 and the second feed 4 for impedance matching.

[0049] In some embodiments, still with Figure 1 As shown, the antenna structure also includes a third frame radiator 7, the extension direction of which is perpendicular to the extension direction of the first frame radiator 1, for example... Figure 1 The first frame radiator 1 extends in the left-right direction, and the third frame radiator 7 extends in the up-down direction. The first frame radiator 1, the second frame radiator 2, and the third frame radiator 7 radiate at least one signal in the same frequency band; for example, the first frame radiator 1, the second frame radiator 2, and the third frame radiator 7 can all be used to radiate the same mid-to-high frequency band signal. When the first frame radiator 1 operates in the satellite frequency band, the first frame radiator 1 and the third frame radiator 7 are fed with equal amplitude and opposite phase. Therefore, utilizing the 90° phase difference between the radiation patterns of the first frame radiator 1 and the third frame radiator 7, and based on the fact that one of the first frame radiator 1 and the third frame radiator 7 is horizontally polarized and the other is vertically polarized, a circularly polarized satellite antenna is synthesized. Furthermore, through the radiation pattern shaping of the third frame radiator 7, such as… Figure 4 As shown, the scanning angle of the first frame radiator 1 can be increased, thereby improving the signal connection speed while keeping the elevation angle between the mobile terminal and the ground constant; after the signal connection is successful, the satellite communication connection of the mobile terminal is always maintained, improving the user's satellite signal experience.

[0050] It is understandable that when the antenna structure is configured in an electronic device, in order to facilitate satellite communication, the first frame radiator 1 can form part of the top frame of the electronic device, and the third frame radiator 7 forms part of the side frame of the electronic device. Therefore, under normal conditions, such as Figure 1 As shown, the radiation pattern of the first frame radiator 1 faces the top of the electronic device, i.e., towards the zenith, while the radiation pattern of the third frame radiator 7 faces the side of the electronic device. There is a 90° phase difference between the radiation patterns of the first frame radiator 1 and the third frame radiator 7. Therefore, when the first frame radiator 1 is operating in the satellite frequency band, it is necessary to maintain the 90° phase difference between the radiation patterns of the first frame radiator 1 and the third frame radiator 7 to achieve equal amplitude and anti-phase feeding.

[0051] It can be designed in the circuit, such as Figure 3 As shown, the antenna structure also includes a third feed 8 and a third switch assembly 9. The third feed 8 is electrically connected to the third frame radiator 7. One end of the third switch assembly 9 is grounded, and the other end is electrically connected between the third frame radiator 7 and the third feed 8. When the first frame radiator 1 is operating in the satellite frequency band, both the first switch assembly and the third switch assembly are grounded via inductors. Alternatively, in other embodiments, when the first frame radiator 1 is operating in the satellite frequency band, both the first switch assembly and the third switch assembly are grounded via capacitors, thereby achieving equal-amplitude, anti-phase feeding of the first frame radiator 1 and the third frame radiator 7.

[0052] In some other embodiments, the antenna structure further includes a fourth frame radiator 10, which is spaced apart from and arranged parallel to the third frame radiator 7 along a second direction. Figure 1 As shown, the fourth frame radiator 10 and the third frame radiator 7 are spaced apart and parallel to each other in the left-right direction; in the second direction, the projections of the fourth frame radiator 10 and the third frame radiator 7 at least partially overlap, and the first and second directions are perpendicular, and the first frame radiator 1, the second frame radiator 2, the third frame radiator 7 and the fourth frame radiator 10 radiate at least one signal of the same frequency band; when the first frame radiator 1 operates in the satellite frequency band, the first frame radiator 1 and the fourth frame radiator 10 are fed with equal amplitude and opposite phase. Thus, by utilizing the 90° phase difference between the radiation patterns of the first frame radiator 1 and the fourth frame radiator 10, and based on the fact that one of the first frame radiator 1 and the fourth frame radiator 10 is horizontally polarized and the other is vertically polarized, a circularly polarized satellite antenna is synthesized, and by shaping the radiation pattern of the fourth frame radiator 10, a reference is still made to... Figure 4 It can be seen that the scanning angle of the first frame radiator 1 can be increased to improve the signal connection speed while keeping the elevation angle between the mobile terminal and the ground unchanged; after the signal connection is successful, the satellite communication connection of the mobile terminal is always maintained, thereby improving the user's satellite signal experience.

[0053] The fourth frame radiator 10 can be designed in the following circuitry. This antenna structure also includes circuitry design options, such as... Figure 3 As shown, the antenna structure also includes a fourth feed 11 and a fourth switch assembly 12. The fourth feed 11 is electrically connected to the fourth frame radiator 10. One end of the fourth switch assembly 12 is grounded, and the other end is electrically connected between the fourth frame radiator 10 and the fourth feed 11. When the first frame radiator 1 operates in the satellite frequency band, both the first switch assembly and the fourth switch assembly are grounded via inductors. Alternatively, in other embodiments, when the first frame radiator 1 operates in the satellite frequency band, both the first switch assembly and the fourth switch assembly are grounded via capacitors, thereby achieving equal-amplitude, anti-phase feeding of the first frame radiator 1 and the fourth frame radiator 10.

[0054] Based on the technical solution of this disclosure, an electronic device is also provided, which includes the antenna structure described in any of the foregoing embodiments. A first frame radiator 1 forms part of the top frame of the electronic device, such that the radiation pattern of the first frame radiator 1 when operating in the satellite frequency band signal faces the zenith direction, which facilitates satellite alignment. A second frame radiator 2 forms part of the bottom frame of the electronic device.

[0055] In some embodiments, the electronic device further includes a ranging component and a processor. The ranging component is used to detect the distance between the bottom edge of the electronic device and the ground. The processor is electrically connected to the ranging component and is used to generate a prompting command based on the difference between the distance detected by the ranging component and the target distance. Specifically, when the distance between the bottom edge of the electronic device and the ground is an odd multiple of 1 / 4 wavelength, the ground can be used as a reflective surface to reflect the radiation pattern of the second edge radiator 2 by 180°, thereby making the radiation patterns of the first edge radiator 1 and the second edge radiator 2 oriented in the same direction. Therefore, the prompting command can be generated based on the difference between the distance detected by the ranging component and any odd multiple of 1 / 4 wavelength.

[0056] Furthermore, the electronic device also includes a display screen electrically connected to the processor. The display screen displays prompt information according to the prompt instructions, instructing the user to adjust the distance between the bottom bezel of the electronic device and the ground. Based on this, when the first bezel radiator 1 operates in a satellite frequency band, the user can adjust the distance between the bottom bezel of the electronic device and the ground to an odd multiple of 1 / 4 wavelength according to the prompt information, thereby shaping the radiation pattern of the second bezel radiator 2 onto the radiation pattern of the first bezel radiator 1, thus increasing the gain of the first bezel radiator 1.
