超宽带引信天线时域建模与仿真

 针对超宽带引信天线的带宽及体积因素, 利用电磁场仿真软件进行超宽带天线建模与仿真。在频域中分析超宽带引信天线的驻波比曲线、天线增益; 在时域中分析超宽带引信天线的辐射信号特性及天线方向图。通过两者结果可以得出, 针对超宽带引信天线, 采用时域分析法为主、频域分析法为辅的方法可得到理想的分析仿真结果。

Time domain modeling and simulation of ultra wideband fuze antenna

To aim at the ultra wideband fuze antenna bandwidth and the volume factor, modeling and simulation of the UWB antenna are studied with computer simulation technology. The UWB fuze antenna voltage standing-wave ratio and antenna gain are analyzed in the frequency domain, and the UWB antenna radiation characteristics of signals and antenna pattern are analyzed in the time domain. In comparison the time domain analysis method is more suitable for ultra wideband antenna. It is shown that for ultra wideband fuze antenna, priority should be given to the time domain method, with the frequency domain method as a supplement, in order to get an ideal simulation result.
