Peano fractal geometries are characterized by their high space-filling properties. In this paper, a new compact dual-mode microstrip filter design, based on this fractal geometry, is presented as a candidate for use in modern wireless communication systems. A bandpass filter with a quasi-elliptic response has been designed based on the 2nd iteration Peano fractal curve at 2.45 GHz using a substrate of a relative dielectric constant of 9.6 and thickness of 0.508 mm. The resulting filter

This represents better miniaturization level compared with the other microstrip bandpass filters with structures based on other space-filling geometries and designed at the same frequency using the same substrate material specifications.Simulation and theoretical performance of the resulting filter structures have been carried out using method of moments (MoM) based electromagnetic simulator IE3D, from Zeland Software Inc.. The results also show that the proposed filter structure possesses good return loss and transmission responses besides the size reduction gained, making it suitable for use in a wide variety of wireless communication applications. Furthermore, the out-of-band response indicates that the proposed filter has less tendency to support higher harmonics
