Abstract:
An antenna signal processing circuit of a smart watch, including: a sensor module, a microprocessor, an antenna body and an antenna tuning circuit having a plurality of tuning paths. The antenna tuning circuit is connected between a smart watch signal source and the antenna body, and the microprocessor is respectively connected to the sensor module and the antenna tuning circuit. The sensor module sends a detected proximity sensing signal to the microprocessor. The microprocessor receives the proximity sensing signal, and obtains a controlling signal, to control the antenna tuning circuit to switch the tuning path and perform tuning processing on a signal from the smart watch signal source or the antenna body. A smart watch and an antenna signal processing method thereof are also provided.
