线框馈电抛物反射面高功率电磁脉冲辐射天线
High power pulse radiation antenna with wire frame TEM horn feedback paraboloid
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700ps、峰值电压为200kV脉冲激励下,天线的主瓣宽度约为±3.8°,辐射效率约为37%。
Abstract
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
