High power pulse radiation antenna with wire frame TEM horn feedback paraboloid

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.
