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 6-10 GHz, especially more than 30 dB from 7.5 GHz to 9 GHz, 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.
