利用 CST MWS 软件建立了引信弹体模型，利用高斯脉冲激励，一次仿真计算，得到了引信天线端口的时域和归一化频率响应。通过改变平面波传播方向及弹体长度，得到了不同仿真结果。仿真结果表明：当平面波传播方向与弹体轴线平行且电场极化方向平行于 T 型天线平面时，引信天线端口的谐振点一定频率范围内的频率响应及时域响应峰值均有最大值；当弹体长度超过一定范围，弹体截断长度对引信天线能量耦合的影响可以忽略。

Mode of fuse projectile is built by using CST MWS.Through one simulation calculation with Gaussian pulse excitation,time-domain and normalized broadband frequency-domain response of fuse an-tenna port are obtained.By changing orientation of plane wave propagation and projectile length,differ-ent simulation results are acquired.The simulation results show that when plane wave propagation direc-tion is parallel to axis of projectile and electric field polarization is parallel to T-type antenna plane,the peak value of time-domain response and the frequency-domain response of antenna port has maximum val-ue when frequency is near by the resonant frequency.When the projectile length exceeds a certain range, the impact of truncated length of projectile on coupled energy to the antenna can be neglected.
