A Fractal-based Dual-mode Microstrip Bandstop Filter for Wireless ApplicationsTechnical Report MRG 2-2016, Microwave Research Group, University of Technology, Iraq (2016)
Bandstop filters (BSFs) are highly required in modern wireless communication and
electromagnetic compatibility related applications. In this paper, a fractal based dual-mode
microstrip BSF has been proposed as a compact resonator structure with high selectivity. Filter
miniaturization results from the application of Minkowski fractal geometry on the conventional
triangle dual-mode resonator. Performance evaluation of the proposed filter design has been
performed using the commercially available EM simulator; Sonnet. Parametric study reveals that
the application of Minkowski fractal geometry results in BSFs offering both a compact size and
high selectivity stopband responses. The results show that the proposed BSF over performs those
reported in the literature in both the size reduction and the realized selectivity.
