摘要: 根据由张量法得到的任意线天线电场计算公式,利用镜像法推导,得到冲击脉冲辐射天线辐射电场的时域解析表达式。应用该表达式计算冲击脉冲辐射天线应用于辐射波电磁脉冲模拟器的时域辐射场,并与数值计算进行比较,结果表明:解析计算得到的辐射场波形与数值计算结果吻合较好,因此,利用解析表达式可以方便地观察天线结构参数对天线辐射场波形的影响,从而选取合适的参数以产生符合标准要求的天线场波形。Abstract: According to the field expression of arbitrary wire antennas obtained through the tensor method, this paper uses the mirror image method to give an analytical expression of the radiation field of impulse radiating antenna in time domain. The expression is then used to calculate the radiation fields of impulse radiating antenna applied to electromagnetic pulse simulator in time domain and the theoretical results are further compared with numerical ones. The results show that, the field waveforms calculated analytically are in good agreement with the numerical results; the effects of antenna parameters on antenna waveform can be easily observed by using analytical expressions, which can help to select appropriate values for parameters to achieve radiated field waveforms satisfying the standard requirements.
