Abstract

We present a miniaturization technique for square dual-mode resonators. By using the Minkowski fractal iteration it is possible to obtain compact resonators. Furthermore the second harmonic is highly attenuated, thus enhancing the rejection in the upper band. A 4^th order filter using two dual-mode fractal resonators has been fabricated to illustrate these results. We use the suspended substrate technology to design these resonators but the results can be extended to other technologies.
