Abstract
In this paper, a new fractal-based microstrip dual-mode band stop filter (BSF) has been
presented. The proposed filter structure is mainly based on that of the triangular patch resonators
with an embedded slit structure. The Koch fractal geometry has been applied to the uncoupled side
lengths of the triangular patch resonator. The filter structure has been modeled, and its performance
is evaluated using the commercially available EM simulator, Sonnet. Results reveal that the
resulting dual-mode response depends heavily on the uncoupled side lengths of the triangular patch
resonator. A parametric study has been conducted to explore the effect of the Koch indentation
angle and the slit length on the resulting filter performance. Simulation results have confirmed the
validity of the proposed resonant structure to realize a compact dual-mode stopband microstrip
filter.
