Those skilled in the art will understand that the embodiments of these antenna frequency band adjustment methods are only some non-restrictive implementation methods provided by the present invention, which are intended to clearly demonstrate the main concept of the present invention and provide some specific solutions that are convenient for the public to implement, rather than to limit all functions or all working modes of the antenna with adjustable frequency band. Similarly, the antenna with adjustable frequency band is also only a non-restrictive implementation method provided by the present invention, and does not constitute a limitation on the execution subject or execution order of each step in these antenna frequency band adjustment methods.
[0043] Please refer to Figure 3 . Figure 3 A schematic flow chart of an antenna frequency band adjustment method provided according to some embodiments of the present invention is shown.
[0044] like Figure 3 As shown, the controller may first obtain the target operating frequency band of the antenna. Then, the controller may selectively connect the first vibrator 111 to one of the first adjustment support point 21 and the second adjustment support point 22 according to the target operating frequency band, and correspondingly connect the second vibrator 121 to the third adjustment support point 23 or the fourth adjustment support point 24, so as to adjust the antenna to the target operating frequency band.
[0045] Please refer to further Figure 4 . Figure 4 A schematic flow chart of an antenna frequency band adjustment method provided according to some embodiments of the present invention is shown.
[0046] like Figure 4 As shown, the controller can determine the bandwidth requirement of the antenna according to the target working frequency band. Afterwards, in response to the bandwidth requirement of the antenna being wide bandwidth, the controller can connect the first vibrator 111 to the first adjustment fulcrum 21, and correspondingly connect the second vibrator 121 to the fourth adjustment fulcrum 24, or connect the first vibrator 111 to the second adjustment fulcrum 22, and correspondingly connect the second vibrator 121 to the third adjustment fulcrum 23, so as to expand the working frequency band bandwidth of the antenna.
[0047] Alternatively, in some other embodiments, in response to the bandwidth requirement of the antenna being a narrow bandwidth, the controller may obtain a center frequency band requirement value of the antenna.
[0048] Afterwards, in response to the center frequency band requirement value being the first frequency band (eg, 5.1 Hz), the controller may connect the first vibrator to the first adjustment fulcrum of the first adjustment branch, and correspondingly connect the second vibrator to the third adjustment fulcrum of the second adjustment branch.
[0049] Alternatively, in response to the center frequency band requirement value being the second frequency band (eg, 5.8 Hz), the controller may connect the first vibrator 111 to the second adjustment fulcrum 22 of the first adjustment branch, and correspondingly connect the second vibrator 121 to the fourth adjustment fulcrum 24 of the second adjustment branch.
[0050] Alternatively, in response to the center frequency band requirement value being the third frequency band (eg 6 Hz), the controller may connect the first vibrator 111 to the fifth adjustment fulcrum 25 of the first adjustment branch, and correspondingly connect the second vibrator 121 to the sixth adjustment fulcrum 26 of the second adjustment branch.
[0051] Furthermore, in order to verify the operating frequency band, bandwidth and efficiency of the above-mentioned antenna with adjustable frequency band provided by the first aspect of the present invention, parameters such as reflection power consumption and scattering coefficient of the above-mentioned antenna may be tested.

Figure 6 A scattering parameter diagram of an antenna with adjustable frequency band provided according to some embodiments of the present invention is shown.
[0053] like Figure 5 As shown, when the above-mentioned adjustable frequency antenna provided by the first aspect of the present invention is only provided with a single oscillator structure, such as only providing the first oscillator 111 or the second oscillator 121, its bandwidth is relatively narrow and the resonance amplitude is shallow in the frequency band of 5.1GHz to 7.2GHz. When the frequency is 5.125GHz, the antenna's return loss (RL) is -10.8dB, and when the frequency is 7.125GHz, the antenna's return loss (RL) is -7.6dB. Figure 6 As shown, when the antenna with the above-mentioned adjustable frequency band provided by the first aspect of the present invention is provided with a dual-element parallel structure, such as setting the first vibrator 111 and the second vibrator 121 at the same time, its bandwidth is widened and the resonance amplitude is deepened. When the frequency is 5.125 GHz, the reflection loss (Return Loss, RL) of the antenna is -11.8 dB, and when the frequency is 7.125 GHz, the reflection loss (Return Loss, RL) of the antenna is -11.6 dB. It can be seen that the antenna with the above-mentioned adjustable frequency band provided by the first aspect of the present application can be provided with a dual-element parallel structure to broaden the working bandwidth of the antenna, thereby meeting the requirements of WiFi 7.

Figure 7A diagram showing the reflection power consumption of an antenna with adjustable frequency band provided according to some embodiments of the present invention is shown. Figure 8 A diagram showing the reflection power consumption of an antenna with adjustable frequency band provided according to some embodiments of the present invention is shown.
[0055] like Figure 7 As shown, the controller connects the first vibrator 111 to the first adjustment support point 21 of the first adjustment branch 112, and the second vibrator 121 to the third adjustment support point 23 of the second adjustment branch 122, so that the working frequency band of the antenna can be adjusted to the 5.1 GHz band. Figure 8 As shown, the controller connects the first vibrator 111 to the second adjustment support point 22 of the first adjustment branch section 112, and the second vibrator 121 to the fourth adjustment support point 24 of the second adjustment branch section 122, so that the working frequency band of the antenna can be adjusted to the 5.5 GHz frequency band.
[0056] Please refer to Fig. 9 , Fig.10 And Table 1. Fig. 9 A schematic diagram of scattering of an antenna with adjustable frequency band provided according to some embodiments of the present invention is shown. Fig.10 The scattering schematic diagram of the antenna with adjustable frequency band provided according to some embodiments of the present invention is shown.
