APPLICATION OF FRACTALS IN THE DESIGN OF MULTIBAND WAVEGUIDE FILTER, POWER DIVIDER AND METAMATERIAL

Abstract

This work is intended to the applications of fractals in the design of various microwave passive components like waveguide filter, waveguide power divider and metamaterial. The idea of using fractals in the design is to achieve multiband behavior in the respective components. In the first part of the dissertation basic theory of fractals, their properties, method of generation have been discussed along with the discussion on the waveguide filter, power divider and metamaterial. Also a designing scenario using fractals in these structures is overlooked with the aim to define established knowledge and possible future development of the research. In the second part of the dissertation numerical simulations of the designed structures of waveguide filter, power divider and metamaterial using Microwave CST Studio, Ansoft HFSS is presented followed by experimental results. The graphical results are generated using MATLAB. And later a conclusion is drawn on the basis of these observations. Experimental results are in good agreement with the simulation results except some marginal errors
