Abstract
Embodiments of a phased array antenna having a plurality of unit cells, each unit cell utilizing an improved electromagnetic band gap (EBG) structure and a lossy material in connection with the EBG element are disclosed. The lossy material reduces the undesired coupling between the antenna radiator and the EBG, thus providing enhanced scanning performance in the phased array aperture.
