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.
