Abstract :
In this paper, we quantitatively compare the radiation pattern stability performance of nine monopole-type UWB antennas (both printed and nonprinted) with the help of a newly proposed figure of merit called the pattern stability factor (PSF). We also determine their overall bandwidth, which is the frequency range within which both matching and pattern stability is very good (i.e. RL >10 dB & PSF >0.95). It was found that the geometry of both the antenna and the ground plane has a significant effect on the overall bandwidth
