In order to improve the anti-static performance of mobile terminal, based on the existing human body model, according to the high-voltage, high-current and a strong feature of electromagnetic radiation features of the electrostatic discharge, we established a mobile terminal electromagnetic radiation model(dipole model), mobile terminal model, and human body-mobile terminal model. Combining with electromagnetic field theory and the features of mobile terminal, we analyzed the electromagnetic radiation model. It is found that the frequency of electromagnetic radiation has crosstalk influence to mobile terminal, and the power of electromagnetic radiation has little influence to mobile terminal. Moreover, when the terminal's input resistance, human body-mobile terminal contact resistance and contact inductance increase, and the terminal's input capacitance and human body-mobile terminal contact capacitance decrease, lower peak current will be obtained. Therefore, we must consider all of these factors that can influence the electrostatic discharge features of mobile terminal and choose the reasonable method in case that these measures can not change the quality of mobile terminal.
