摘　　要：为了研究电火工品在复杂电磁环境下的射频安全性,针对某型电火工品建立了偶极子天线模型。基于CST电磁仿真软件,仿真得到了该天线模型的增益参数,进一步仿真计算得到了在频率为0.75GHz、电场强度为195V/m的电磁环境下,进入到该电火工品的射频功率,并与实际计算结果进行了对比验证。通过多频点仿真计算,得到了该天线模型的增益随频率变化的规律,即在0.5～2.0GHz的频率范围内,天线模型的增益随着频率的增大而增大。In order to study the radio frequency safety on electric explosive device （EED） in complex electromagnetic environments, a dipole antenna model for a certain type EED was established. Based on the CST software, the gain pa- rameter of the antenna model was obtained. For further simulation, the radio frequency power into the EED at a frequency of 0.75GHz and an electric field strength of 195V/m was calculated. The simulation results were compared with the practi- cal calculation results. Through the multi - frequency simulation, it implies the tendency that the antenna gain is increasing as the frequency increases in the 0.5 - 2.0 GHz frequency range.
