The advances in wireless technology and the ever-growing demand for multiband and smaller antennas in wireless communications has led to the field of mathematics known as fractal. The use of fractal geometry in antenna design has created a significant amount of interest within the wireless communications societies and most importantly, antenna design.
This thesis investigates the performance and optimization of fractal antennas used in wireless communications. The principle analytical tool utilized in the study is the Finite Difference Time Domain technique (FDTD). This numerical method was applied to calculate the electromagnetic propagation characteristics of the Sierpinski gasket and Koch snowflake fractal antennas.
Numerical results were computed for the two fractal antennas and compared to a conventional antenna. The input impedance, radiation pattern, the return loss and far field condition of these antennas are computed and analyzed. The Finite Difference Time Domain (FDTD) simulated results were collected and showed to be in good agreement.
