The imminent wide scale commercial deployment of ultra-wideband (UWB) systems has led to increased interest in UWB antenna designs. This thesis is motivated by the need for an effective method to design a high performance UWB antenna. In sharp contrast to the traditional antennas, UWB antennas require to be designed from a novel perspective. The efforts made in this thesis are dedicated to paving the way for a robust optimized design of a UWB antenna system. Since a basic design procedure is completed by four key ingredients: input model, characterization, evaluation and then optimization, all of them are in the scope of our study while special emphases are paid on the methods for characterization and optimization.
