|Abstract:||The report evaluates the performance of an indoor positioning system using Impulse Radio Ultra-Wide Band (IR-UWB) technology with wearable antennas. Moreover, it represents the study of accurate body worn antenna localisation in on the line of sight (LOS) and non-line of sight (NLOS), which is suitable for locating and tracking the objects in a small area such like household environment. An array which contains a number the directional UWB Vivaldi antennas are on individual adjustable robotic-based supports which are in different anchor positions in the 2m×2m×2m scanning area. The National Instrument(NI) MyRIO board is utilised to adjust the position and angle of the above anchor antennas. Moreover, one compact body is worn transmitting UWB antenna placed on the both shoulder of the human body. The proposed system is based on a portable Vector Network Analyser (VNA) and a switching network to connect above UWB antennas. The received UWB data is acquainted via a computer using NI LabVIEW and then processed using the time of arrival (TOA) based positioning algorithm using Matlab. A different configuration of transmitting antenna array and effect of the human body on receiving antenna on localisation accuracy is analysed through measurements.|
