A unique slitting approach harmoniously marries the Vivaldi antenna and metamaterial together, where a single layer metamaterial piece is simply snug into the slit perpendicular to the middle antenna substrate. The major improvement in the spotlight is the capability of metamaterial to focus the entire beam to radiate onto the targeted direction. The comparison between modified Vivaldi antenna and the ones improved is introduced, concluding that the snug and boost method applied on the antenna is capable to fit broad sphere of ultra-wideband applications.
