In a specific implementation, as shown in FIG. 3 , the tuning circuit 111 may include a plurality of working states. Under different working states, at least one of the capacitance value and the inductance value of the tuning circuit 111 is different. The circuit 111 may include an adjustable capacitor and an adjustable inductance, so that the working state of the tuning circuit 111 can be adjusted by adjusting the capacitance value of the adjustable capacitor or the inductance value of the adjustable inductor; or the tuning circuit 111 may also include a selection switch, And the free end of the selection switch is connected with different capacitors or inductances, so that the working state of the tuning circuit 111 can be adjusted by controlling the free end of the selection switch.

During work, the same user often inserts the belt needle 32 into the fixed belt hole 22 .

The branch and tuning circuit 111 is used to tune the loop antenna formed by the target antenna branch and the target part of the first antenna assembly 21 through the tuning circuit 111, so as to improve the antenna performance of the loop antenna. In the application, when the user wears the wearable electronic device, the length of the target portion in the first antenna assembly 21 is fixed, so that when the working frequency band of the wearable electronic device is switched, the wavelength suitable for the working frequency band can be determined. If the target antenna length is assigned, then a certain antenna branch can be determined as the target antenna branch when the sum of the length of a certain antenna branch and the length of the target part is the closest to the target antenna length, so that the target antenna branch can be Connected to the tuning circuit 111 . In addition, in this embodiment, the structural parameter of the loop antenna further includes the length of the target antenna branch.
