Antenna arrays based on one or more metamaterial structures

摘要

a base layer having a metamaterial structure; printed circuit board (PCB) layers; a feed layer disposed on the opposite side of the PCB layer from the RF IC(s); and an emissive layer disposed over a feed layer comprising a plurality of emissive elements, wherein the metamaterial structure is disposed to attenuate electromagnetic radiation propagating between at least two adjacent waveguides in a frequency band. An antenna array is disclosed.
