摘　　要：介绍了利用充氮气自击穿开关产生双极脉冲，并通过同轴双锥天线辐射的实验研究。实验获得电压约±１００ｋＶ，脉冲宽度小于等于３．６ｎｓ，工作频率单次、１０Ｈｚ和１００Ｈｚ的双极脉冲；同轴双锥天线带宽１５０ＭＨｚ～１ＧＨｚ，峰值功率辐射效率达６５％。A high voltage bipolar pulse generated by self-breakdown switch filled in nitrogen and radiated by coaxial-conic antenna is described. It consists of the pulse power systems, switches, bipolar pulse forming line(BPFL)and UWB antenna. The bipolar pulse with the voltage～±100kV, duration≤3.6ns and pulse rate single, 10Hz and 100Hz is realized; and the radiation from the antenna with bandwidth from 150MHz to 1GHz, and peak power radiated efficiency ～65% has been obtained. The results of the numerical simulation of the UWB antenna practically coincided with the experimental one.
