摘要
研制了一种由高功率宽带模式转换结构、导电线框 TEM喇叭馈电结构及抛物反射面构成的天线 ,用其辐射高功率亚纳秒电磁脉冲。时域测试表明 ,在半宽为 70 0 ps、峰值电压为 2 0 0 k V脉冲激励下 ,天线的主瓣宽度约为± 3 .8°,辐射效率约为 3 7%
An antenna was developed to radiate high power, sub nanosecond EM pulse, which consists of a high power wideband mode convertor, a wire frame TEM horn feedback set and a parabolic reflector. The radiation E field pattern is about ±3.8° and radiation efficiency is 37% when the antenna is execited by a pulse of 700ps duration and 200kV peak voltage. Compared with those antennas with face to face TEM horns or co planar TEM horns, this kind of antenna has the best radiating property.
