Ultra-wideband (UWB) technology is rapidly developing as a high speed and high data rate wireless communication mode. There are many challenges in dealing with this new emerging technology. One of these challenges is how to design an antenna element that can operate effectively in the entire UWB frequency range. Another big challenge is to design UWB antenna beam-forming systems include suitable UWB components such as feed networks, transitions, crossovers, hybrid couplers and phase shifters to meet the UWB requirements.
