摘    要:利用时域有限差分方法(FDTD),结合端接负载模型,计算某指挥控制系统置于方舱上壁的鞭状天线的超宽带(UWB)耦合效应。计算结果表明:该天线在超宽带环境中耦合的最大电流在35 A左右;当入射波的电场方向与天线方向一致时,天线上可以感应更大的电流;由于方舱上壁反射电磁场的作用,当仰角在120°左右时,天线上的感应电流峰值最大;超宽带脉冲平行于车长方向入射该系统能比垂直入射该系统,感应出更大的电流。

关 键 词:通信电台  天线  超宽带  耦合效应

Abstract:The coupling effects of the UWB on the flagelliform antenna, which is placed on the shielding cell of a command and control system, are calculated with the FDTD method and the loaded wire model. The obtained results show that the maximum coupling current is about 35A;the induced current is bigger when the antenna is parallel with the polarization direction of the incident field; the induced current reaches its maximum value when the elevation angle is about 120° with the effect of the shielding cell upper surface ; the induced current is bigger when the UWB incident direction is parallel with the vehicle.
Keywords:communication radio  antenna  UWB  coupling effects
