In this article, the resonant behaviors of the Sierpinski‐based fractal resonators were investigated first. The design guideline for the filter using the nth order resonator is then developed. A two‐pole filter example centered at 2.2 GHz based on the 3rd order Sierpinski‐based resonators was designed and fabricated. Measured results have a good agreement with the simulated results and verify the advantages of the size and insertion loss reduction as compared with the filter using conventional patch resonators. © 2008 Wiley Periodicals, Inc.
