Microwave reduction of square Sierpinski factal based metallo-dielectric structure

The microwave reduction of square Sierpinski fractal based metallo-dielectric structure is studied. We find that microwave reduction is obtained for the structure with frequency about 6–10GHz, especially more than 30dB from 7.5GHz to 9GHz, by finite element method (FEM). And the measured data have verified the validity of computation. Furthermore, we have presented a fitting linear equation and a fitting curve to describe the relationship between reduction peak frequency vs dielectric thickness. These may have application in stealth of aircrafts or ships and the design of Frequency Selective Surfaces.
