1. An ultra wide band (UWB) antenna, comprising:
a planar cap portion that is parallel to a ground plane;
a tapered portion that extends vertically away from the planar cap portion and toward the ground plane and that forms a cavity vertically between a bottom surface of the tapered portion and the ground plane; and
a side portion that extends around a periphery of the planar cap portion, that extends vertically from the planar cap portion toward the ground plane, and that electrically connects to a feed at a point that is vertically above the cavity,
wherein the side portion includes at least six curved portions.
