碩士 === 大同大學 === 通訊工程研究所 === 98 === For the electromagnetic conducted susceptibility test, the coupling disturbance is usually considered from the charger side and the response on headset side is observed. In this thesis, we consider the situation that the test equipment involves FM function and has to use earpiece as FM antenna. Since the length of earpiece is over than 1 meter, the coupling disturbance may result from the headset side and thus we need to monitor the response on the same side. After briefly introducing the mobile phone history, fundamental of mobile phone, and EMC test, we focus on the electromagnetic conducted susceptibility test of mobile phone using earpiece as FM antenna and provide a low cost and simple method to improve the performance.
