Abstract :
In this paper, we describe an antenna and pulser system designed to radiate an impulse-like waveform. Specifically, we have analyzed, designed, fabricated, and tested a reflector antenna fed by a pair of conical transmission lines. The voltage waveform that feeds the antenna is a fast-rising (10-90% rise of ~100 ps), slowly decaying (e-fold decay of 20 ns) pulse with a differential amplitude of ±60 kV. The calculated and measured bore-sight-radiated field, at a distance of 304 m, is impulse-like with a peak amplitude of 4.2 kV/m
