Abstract

This report elaborated on the theories and techniques in the process of shrinking the size of an antenna through the usage of fractals. The Minkowski fractal patch antenna was investigated. The Minkowski fractal patch antenna was introduced in order to reduce the size of antenna using miniaturization technique. This project presented the design of fractal patch antenna based on the basic structure of square antenna operating at 2.45GHz for Wi-Fi application. The fractal design was introduced into the basic structure for the purpose of reducing the size of the elements. Thus, an expectation would be set on the miniaturization to be achieved. Simulations wave performed on several sets of the structures design using Computer Simulation Technology Software. The simulation result showed that the fractal iteration and the iteration factor had different effects on the reduction of the patch antenna. From the experiment, the result showed that the 1st and znd iteration Minkowski fractal patch antenna managed to reduce the antenna size, while maintained the same resonant frequency as that of the normal square patch antenna. Fractal antennas can obtain radiation pattern and input impedance_ similar to a longer antenna, yet take less special area due to the many contours of the shape. Fractal antenna is a fairly new research area and more likely to have a promising future when used and designed into whole other applications.
