Abstract

Self-similarity and space filling property of fractal geometries are explored in the design of frequency selective diaphramgs in rectangular waveguide. Several fractal geometries like Siepinski gasket, Sierpinski carpet, Hilbert curve, Minkowski fractal, plus shape fractal, Devil’s staircase fractal geometries are investigated which can be efficiently used in realizing light weight, compact and multiband waveguide filters and electromagnetic band gap (EBG) structures. It is demonstrated that the fractal geometries can reduce the resonant frequency of the diaphragms substantially and it is shown the scale factor of the fractal geometries can be used to suitably position the resonant bands.
