ABSTRACT:
An array antenna may include a substrate, an array of metamaterial elements including radiating elements suspended in the substrate and integrated with the array of dipoles, where the metamaterial elements include a first metal layer and a second metal layer connected by a via, an array of dipoles, a groundplane coupled with a first side of the substrate, the ground plane having a symmetric slot aperture and not contacting the array of metamaterial elements, and a stripline feed for the radiating elements, where the stripline feed passes from a groundplane first side through the symmetric slot aperture to a groundplane second side.
