Three major areas of activity in antenna research and development have emerged to meet the needs of modern communications system, size reduction, wideband and multiband operation and large gain. For faster transfer of information in business world without cables or adaptors would require antennas that are not only low profile and lightweight but also simultaneously operate at desired frequency bands. In this book, the author proposes a new multiband staircase antenna based on fractal shapes for frequency range of (2 to 10 GHz). Generally, fractals are objects, which display self similarity on all scales. Fractal technology allows us to design miniature antennas and integrate multiple telecommunication services into a single device. Due to this advantage, several multiband antennas operating both for Wi-Fi and WIMAX have been proposed. Fractal antenna due to their multiband and reduced size has drawn the attention of researchers. Therefore, the author focuses their attention to design a new fractal antenna.
