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...
In addition, I would also like to thank Professor -------------for connecting me with the Laboratory sp that I could carry out all my important measurements to bring out a clear and enhanced project report.
I cannot entirely endow the success of this project only to people at this particular project work with me. I am thankful to those who have supported me throughout these years at the university through their true friendship and thoughtfulness. My family has been an incredible pillar of support including my wonderful parents.
I cannot single out any one person who has been the sole support for this project report. I would like to thanks every one whom I might have missed out.
