基于Valentine天线的辐射原理，设计出可发射峰值电压610 kV、频谱范围0.2~2 GHz高功率脉冲的超宽带天线。利用油作为绝缘介质过渡巴伦可使天线直接加载于50 Ω的同轴波导上；通过优化填充介质及天线拓扑结构提高了耐压能力及辐射特性。仿真结果表明，设计的天线具有低反射、宽频带、高增益和高耐压强度等优点。

In this paper, a novel antenna based on the radiation principle of Valentine antenna is designed to radiate high-power short pulse with a 610 kV top voltage and an FFT spectrum of 0.2-2 GHz. The coaxial-to-parallel-strip balun filled with transformer oil is deployed to feed the antenna with a 50 Ω coaxial waveguide. The dielectric strength and radiation property are optimized by the dielectric material and topology structure of the antenna. Simulation result shows that the antenna has a low reflection, ultra wideband, great gain and high dielectric strength.
