UWB Antenna Characterization and Optimization Methodologies
This paper presents a set of UWB (Ultra-WideBand) antenna performance metrics that have proven to be extremely beneficial at characterizing, and hence, optimizing, both dispersive and non-dispersive UWB antennas for a variety of applications. The UWB antenna performance metrics presented herein are based on a normalization procedure that emphasizes changes in the radiation pattern as a function of frequency, time, angle, and polarization. These performance metrics provide a natural and understandable method to characterize UWB antenna performance and valuable insight into the radiation mechanisms within the antenna.
