Abstract
The present invention is directed to antenna system embodiments which allow for hand-held, ultra-wideband (UWB) multi-antenna operation to be realized within the severe size constraints necessary for Department of Defense (DOD) hand-held missions. Further, the antenna system embodiments disclosed herein provide a miniature UWB multiple antenna solution for multiple-input and multiple-output (MIMO) and radiation pattern null steering suitable for hand-held soldier radios.
