Isosceles triangle Sierpinski Gasket antenna´s multiband analysis with an iterative method

The multiband behavior of isosceles triangle Sierpinski Gasket antenna is studied in this paper with an iterative method. Based on a Sierpinski Gasket antenna which has finite iterations, a multiport network iterative model has been built to analysis the S parameters. The model is simple, but the computational result has effective prediction in antenna´s multiband. Comparing with equilateral triangle one, this paper´s result is more complex but representative. The measured data from other papers´ has assessed the result´s validity.
