| ABSTRACT: An antenna for producing an output pulse of desired duration in response to an impulsive wave front includes a resistive plate mounted above a ground plane. A coaxial transmission line projects through the ground plane so that its center conductor contacts the resistive plate and its outer conductor terminates flush with the ground plane. The resistive plate consists of a submicron film of resistive material deposited on a dielectric backing and is spaced from the ground plane at a distance approximating the distance travelled by an electromagnetic wave in a time equal to the desired pulse duration. | |||
