Miniaturized Thin Soft Surface Structure Using Metallic Strips with Ledge Edges for Antenna Applications

Published by and copyright of The Electromagnetics Academy. The definitive version of this article is available at: http://www.jpier.org/PIERB/pier.php?paper=13092601A new thin electromagnetic soft surface of strips in which ledge edges are used to reduce\ud the strip period width and in turns a miniaturized structure is achieved. The surface is tested to reduce\ud the mutual coupling between microstrip patches separated by a half wavelength in free space (center-to-\ud center). A 20% relative bandgap bandwidth is achieved. The measurements revealed good agreement\ud with the simulated results
