Ultra-wideband Communication Systems
Pages 18 (4518 words)
The American Military had been using ground breaking radar systems, wall imaging technologies until now. With the evolvement of the new Ultra-wideband (UWB) communication system, the transmission speed has increased by multiple folds bringing about low power dissipation, and low chip space.
Ultra Wideband antenna requires the operating bandwidths as 100% of the center frequency and the successful broadcast of these Ultra Wideband signals that occupy the 3.1-10.6 GHz spectrum, requires the antenna to be in a linear phase, having low dispersion and its VSWR 2 all over the entire band. These properties (linear phase, low dispersion) are imperative for the transmission and reception of signals with least distortion. VSWR 2 is required for optimum impedance matching which ensures that a maximum 90% power radiation. The study further suggests that the Ultra Wideband antenna will only be compatible in case of a small integrated design circuit, which achieves the aim of a physically compact, planar Ultra Wideband antenna with sufficient impedance bandwidth, high radiation pattern and near omni directional radiation pattern.
First and foremost, I take the opportunity to thank my advisor, -----------------, for the opportunity he has given me to work on this project, and also for his amicable support and assurance in my work. His endurance and back-up were priceless to me all through the track of this research. He is the one to give a constant and essential push to me to be able to perform to the best of my capability. I am extremely grateful.
I would also like to express gratitude to the entire UWB group f ...
