The ultra wideband (UWB) is one of the most promising technologies for future communication systems due to its high-speed data rate and excellent immunity to multipath interference. In this context, the UWB antenna design plays a unique role because it is the “ears” and “eyes” of any wireless communication system. Some of the critical requirements in UWB antenna design are: ultra wide bandwidth, directional or omni-directional radiation patterns, constant gain and group delay over the entire band, high radiation efficiency and low profile. This work reviews the characteristics and the configuration of the most important patents on UWB antennas including the recent patents on this topic.
