A fractal absorber based on a metamaterial configuration is proposed for dual-frequency operation within the UHF band. The miniaturization skills of the proposed fractal shape are used to design a dual-band metamaterial absorber cell with reduced size and a very thin substrate thickness. A metamaterial absorber panel is fabricated and tested to validate the performance of the proposed fractal based metamaterial absorber cell. Good agreements between full-wave simulations and experimental results are demonstrated.

Abstract
A fractal absorber based on a metamaterial configuration is proposed for dual-frequency operation within the UHF band. The miniaturization skills of the proposed fractal shape are used to design a dual-band metamaterial absorber cell with reduced size and a very thin substrate thickness. A metamaterial absorber panel is fabricated and tested to validate the performance of the proposed fractal based metamaterial absorber cell. Good agreements between full-wave simulations and experimental results are demonstrated.File in questo prodotto:
