| 摘 要： | 将超宽带电磁脉冲天线组阵后可提高主射方向的峰值功率及增益。但由于非线性阵元因素,必须考虑阵元间互耦效应。以恒阻抗TEM喇叭天线为阵元,通过仿真和实验研究了超宽带天线阵的互耦效应,研究表明,耦合强弱与阵元间距及频段有关,互耦增强了超宽带天线阵的低频辐射能力,使远场主射方向脉冲峰峰值有所增加。上述结论对于超宽带电磁脉冲天线阵的应用具有参考价值。

| Abstract: | Ultra-Wideband(UWB) impulse radiation antenna arrays are widely used for its flexible radiation pattern and high gain.However,inter-element mutual coupling should be studied carefully because the arrays involve non-linear elements.Simulation and experiments taking constant impedance TEM horn as an array element show that mutual coupling is closely related to inter-element distance and frequency band.Mutual coupling increases radiation power in low frequency band and boosts the magnitude of pulses in the pri... |
