Abstract
An ultra wide band (UWB) antenna is described and includes: a planar portion arranged above and parallel to a ground plane; a ground connecting portion configured to electrically connect the UWB antenna to the ground plane; a tapered portion, the tapered portion extending around at least 40 percent of a periphery of the planar portion and extending perpendicularly from the planar portion toward the ground plane, where a height of the tapered portion decreases around the periphery of the planar portion moving away from the feed, and where a lower edge of the tapered portion is spaced from the ground plane by a gap; and a radio frequency (RF) balun, where a feed is configured to be electrically connected between the RF balun and the tapered portion.
