摘要

高空电磁脉冲(High-altitude electromagnetic pulse, HEMP)对工作在甚高频(VHF)或高频(HF)频段的通信系统构成严重威胁。为了分析安装在导电平面上的单极天线的位置对其瞬态响应的影响，将典型的电磁计算方法-矩量法与傅里叶变换相结合，得到了单极天线的瞬态响应。通过商用电磁软件和辐射测试验证了该方法的有效性。利用HEMP入射波的两种场分布形式，分析比较了单极子安装在导电平面不同位置时单极子天线端口SC电流和负载电流的瞬态响应。研究结果对实际应用场景下的天线布置具有一定的指导意义。

Transient Response Analysis of Monopole Antenna Mounted on Conductive Plane Varying Different Positions

High-altitude electromagnetic pulse (HEMP) leads a serious threaten to the communication systems with working in the frequency range of VHF or HF. For analyzing the effect of the positions of monopole antenna mounted on a conductive plane to its transient response, the combination of a typical electromagnetic computing method- method of Moment and Fourier transform is used to obtain the transient response. The procedure validation is proved with commercial electromagnetic software and radiation test. With two field distribution configurations of HEMP incident wave, this paper provides the analysis and comparison of transient response for the SC current and load current of monopole antenna port when monopole is mounted on different positions of a conductive plane. The results are meaningful to the antenna placement in practical application scenarios when considering HEMP environment.
