DESIGN OF COMPOUND FRACTAL ANTENNA FOR MULTIBAND APPLICATION

Abstract

This work is concerned with the investigation of two types of antenna elements that are to be used for multiband applications. The first antenna is the Fractal antenna while the second is the meander line antenna. The basic design is based on the self similarity principle of fractal profiles but uses different slot geometries. The behaviors of both type antennas are investigated such as return loss, number of iterations and radiation pattern. Compound fractal antennas have the potential to provide multi - band solution through the property of self similarity that the fractal shape poses. Compound fractal antenna is comprised of elements patterned after self similar designs. Self - similarity of the fractal shape can be translated into its electromagnetic behavior. Nowadays wireless communications systems require compact antennas which are capable of operating at different bands. Fractal geometry is being studied in order to answer those requirements.
