## Abstract Microstrip stepped‐impedance transformers using a Sierpinski fractal shape are proposed for the first time. The proposed fractal‐shaped stepped‐impedance transformers can greatly enhance the operating frequency bandwidth. Bandwidth up to 44.0% and 73.9% (__S__~__11__~β‰€βˆ’30 dB) have been
