Abstract
A method for determining the phase center location of ultra-wideband monopole antennas is presented and used to investigate its movement within the frequency band of the antenna. It is then used to study the effects of different band-stop designs on the degree of the phase center movements. It is shown that some designs can adversely affect the phase of the radiated field, by displaying larger phase center movements. For improved performance of the UWB antennas, such designs must be avoided.
