Abstract
This paper presents a compact printed antenna for UWB ranging over the 3.1-10.6 GHz FCC assigned band. The radiation pattern and polarization are very stable over the entire UWB band. Preliminary line-of-sight (LOS) ranging measurements are performed and range information is extracted from the pulse signal time delay between two identical UWB antennas. The antenna link performance is measured, presenting very low pulse distortion effects. Early results demonstrate quite accurate position estimation from measurements performed in different scenarios, with errors below 1.5 cm.
