The ultrawideband antenna frontier

Ultrawideband (UWB) systems have attracted great attention in recent years with their potential to support the large data bandwidths of modern media streams. To meet these needs, early UWB antenna designs have been rediscovered and improved upon, and a new generation of UWB antenna designs is emerging. This talk will present a historical introduction to UWB antennas. The importance of learning the lessons of the past to avoid re-inventing earlier designs will be emphasized. Then, this talk will provide a brief survey of a new generation of UWB antennas including planar dipoles, improved monopole elements, and integrated feed structures. Finally, this talk will discuss future directions in UWB antenna practice, including using antennas to control spectral response and combining electric and magnetic antennas to create compact gain antennas.
