Abstract

An antenna having improved front-to-back ratio, the antenna comprising: a backplane; at least one driven antenna element positioned on a forward side of the backplane; and first and second deflector plates disposed on opposing edges of the backplane, the first and second deflector plates extending rearwardly and outwardly from the opposing edges of the backplane.
