【摘要】 研制了一套16阵元的小型超宽带喇叭阵列天线,阵元天线由渐变横向电磁场(TEM)喇叭加框型电流环构成,分析了设计原理结构,给出了数值模拟结果并进行了试验研究。在每个单元馈入峰值电压4 k V,前沿180 ps超宽谱脉冲时,获得了r E值82 k V。整个系统紧凑小巧,具有较高的辐射效率,适合低功率情况下超宽谱脉冲的辐射。更多还原

【Abstract】 A 16-element array for ultra high repetition pulse is implemented. The antenna element consists of a Transverse Electric and Magnetic Field(TEM) horn and a current ring. The design principle is analyzed. Simulation and experiment are performed. Results show that the r E value is up to 82 k V when the antenna elements are excited by a pulse of 180 ps risetime and 4 k V peak voltage.更多还原
