Title:
SMART WATCH AND ANTENNA SIGNAL PROCESSING CIRCUIT AND METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/121379
Kind Code:
A1
Abstract:
An antenna signal processing circuit of a smart watch, the circuit comprising: a sensor module (11), a micro-processor (12), an antenna body (13) and an antenna tuning circuit (14) with a plurality of tuning passages. The antenna tuning circuit (14) is connected between a smart watch signal source (15) and the antenna body (13), and the micro-processor (12) is respectively connected to the sensor module (11) and the antenna tuning circuit (14). The sensor module (11) sends a detected proximity sensing signal to the micro-processor (12); the micro-processor (12) receives the proximity sensing signal, and obtains a control signal to control the antenna tuning circuit (14) so same switches a tuning passage to perform tuning processing on a signal from the smart watch signal source (15) or the antenna body (13). The proximity sensing signal detected by the sensor module (11) is used to determine a wearing state of a smart watch so as to switch the antenna tuning circuit (14) to a tuning passage corresponding to the wearing state and adjust the antenna performance, so that an antenna system is suitable for the current wearing state, thereby ensuring that the antenna system is automatically switched to the optimal state and improving the quality of an antenna signal. Also provided is a smart watch and an antenna signal processing method therefor.
