Abstract

In recent years, the demand for compact and multi-function handheld communication devices has grown significantly. Devices having internal antennas have appeared to fill this need. Antenna frequency band and size are major factors. In the past few decades, fractal antenna theory develops rapidly, basing on fractal geometry to maximize the length of material. Fractal surface is a function of roughness, by increasing roughness, polarization changes. For this reason, fractal antennas are very compact, are multi-band and have useful applications which require small, cheap and effective antenna such as cellular telephones and microwave communications. Anotable fractal antenna to be mounted on wireless devices such as mobile phones, laptops is presented in this thesis. The proposed multi-band fractal antenna simultaneously operates in the IEEE 802.11a, IEEE 802.1 lb/g and WiMax frequency bands. The multi-band behavior is obtained by using Sierpinski Gasket fractal structures. The overall size of the antenna renders it suitable to be installed at the back of the mobile phone or the top of the display of a notebook. Simulation results are obtained by CST Microwave studio.
