| 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 |
