Abstract
An ultra wide band receiver system comprising a ultra wide band antenna and an active circuit. The ultra wide band antenna including a power feed operable to receive electromagnetic energy. The ultra wide band antenna further includes a radiator operable to be excited by the electromagnetic energy fed through the power feed to radiate an electromagnetic wave. The radiator has a metal layer. The active circuit includes a pair of parallel coupled lines arranged on a first side of the radiator. The pair of parallel coupled lines is operable to block DC current. The active circuit further includes at least one defected ground structure formed on a second side of the radiator. The defected ground structure is formed on an etched out part of the metal layer.
