Abstract
A new compact microstrip bandpass filter
design is presented in this paper as a candidate for use in
modern wireless communication systems. The proposed
filter structure is composed of two fractal-based
microstrip resonators. The structure of each resonator is
in the form of the 3rd iteration Peano fractal curve. The
resulting filter structure based on these resonators, shows
a considerable size reduction compared with the other
microstrip bandpass filters based on other space-filling
geometries designed at the same frequency. A second
bandpass filter design based on the same resonator but
with a tuning stub has been also presented, in an attempt
to provide practically useful means to tune the filter to the
specified performance with a considerable tuning range.
The performance of the resulting filter structures has been
evaluated using a method of moments (MoM) based
electromagnetic simulator IE3D, from Zeland Software
Inc. Results 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. Furthermore, performance responses show
that the second filter, based on Peano shaped resonator
with stub, has less tendency to support the 2nd harmonic.
