ABSTRACT:
An antenna having two frequency-selective surfaces is disclosed. The antenna includes a first frequency-selective surface (FSS) having multiple holes to form a mesh, a second FSS having a multiple holes to form a mesh, and a perfect electric conductor located between the first FSS and the second FSS.
