A novel broadband electromagnetic band-gap based on Sierpinski Gasket triangles
The characteristics of a novel broadband electromagnetic band-gap (EBG) design based on Sierpinski Gasket triangles are presented in this paper. These triangles, which are the equilateral triangles, are arrangement repeated each 600 to introduce the hexagonal unit cells without vias. Model of this EBG structure have been developed and constructed on an inexpensive Fire-Retardant 4 (FR4) with thickness of 1.6mm and relative permittivity of 4.4. Direct transmission method is used to determine the band-gap of the EBG structure. The EBG operation bandwidth is about 87% at the center band-gap frequency.
