Antennas having rf lenses that include meta-structures that form step approximations of luneburg lenses and related rf lenses

Abstract

An RF lens comprises a multilayer printed circuit board that comprises a plurality of dielectric layers and a plurality of metallization layers that are alternatingly stacked, the plurality of metallization layers including at least a first metallization layer and a second metallization layer. Each metallization layer comprises a plurality of meta-structures. The meta-structures are arranged to form a step approximation of a Luneburg lens in at least one direction.
