The disadvantages are that the process is complicated and the cost is high; the product has a strong plastic feel and no texture; because it is made of plastic, the entire body is not strong enough.

[0005] FPC and external antenna: A conductor suitable for the corresponding wavelength is attached to the inside of the plastic shell as an antenna. The disadvantages are that it is large in size and has requirements for the external dimensions, otherwise it is difficult to process; the product has a strong sense of plastic and lacks texture; the entire body is not strong enough because it is made of plastic; the frequency band required for GPS reception is basically ultra-low frequency, which requires ultra-long bandwidth, and the size of the wearable device is too small, so the performance of the external conductor is difficult to meet the actual requirements;
