On some implementation issues for time-domain, pulse-matched synthesized antennas

Low-distortion antennas for pulsed excitation can be synthesized by using a technique based on a finite expansion of the antenna time-domain response. Current profiles can therefore be generated in order to achieve optimal response for a given waveform of excitation. However, the simplest radiating structures resulting from synthesis might neither provide acceptable input matching, nor omnidirectional radiation. This paper addresses these two issues and further proposes two antenna structures.
