Abstract

A conformal metamaterial absorber operating at the quad band is analyzed in this paper. The proposed structure is fabricated on a 0.5 mm thick, flexible polyester dielectric substrate. The proposed structure works at the chosen frequencies 4.11 GHz, 5.37 GHz, 7.39 GHz and 8.4 GHz with the absorptivities of 96%, 95%, 90% and 94%, respectively. The structure has essential novelty of miniaturization of λ/146 in the thickness, which is an exceptionally flexible material for Radar applications. Quad band excitation can also be analyzed by the iteration of the proposed structure as well as circuit analysis. The flexible polyester material is etched with silver coating for the development of the fabricated structure. The simulated results can also be associated with the measured ones from the planar as well as a cylindrical surface to realize flexibility for stealth technology. It can be accomplished by the free space measurement technique in an anechoic chamber.
