| Summary: | 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. |
