We summarize here a number of advances in Impulse Radiating Antennas. These devices are composed of a reflector and a broadband feed. We have demonstrated improved gain and reduced crosspol by using feed arms located at f30" to the vertical, as opposed to the original desip that placed the arms at k45O. We have reduced the return loss (flattened the TDR) at the splitter, at the feed point (focus), and at the resistors in the feed arms. We have added a ground plane that enhances mechanical stability and reduces crosspol. We have also improved the mechanical stability of the feed point.
