ANTENNA ARRAY BASED ON ONE OR MORE METAMATERIAL STRUCTURES

摘要

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