Abstract
A new compact narrowband multiresonator microstrip filter design is
presented in this paper as a candidate for use in modern wireless
communication systems. The proposed filter structure is generated using
Peano fractal curve geometry. The proposed filter structure is fractally
generated using Peano fractal curve geometry. Two 2nd and 4th order
Chebyshev bandpass filters have been designed based on the 2nd iteration
Peano fractal curve at a design frequency of 2.45GHz using a substrate of a
relative dielectric constant of 9.6 and thickness of 0.508 mm. Filter structures
based on the second iteration Peano geometry leads to compact size single
mode resonators with dimensions of about (0.075×0.086)-g. This article
represents better miniaturization level compared with the other microstrip
bandpass filters 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 structures possess good return loss and transmission
responses besides the size reduction gained, making them suitable for use in a
wide variety of wireless communication applications.
