Abstract

This paper presents a novel waveguide band pass filter using Sierpinski fractal-shaped irises. The bandwidth of the proposed filter is more than 5.5 times in comparison to similar waveguide filter with rectangular shape iris. The offered filter is designed and simulated using Ansoft HFSS and then fabricated. The results show less than 0.5 dB insertion loss and return loss better than 13 dB in operation frequency band for the proposed filter.
