Reader Antenna Beam Width Optimization under Multiple Channel Effects in a UWB-RFID System
Résumé
This work addresses the performance of a system of four Ultra Wide Band (UWB) readers for the detection and localization of RFID tags operating in modulated backscattering. Several effects involving the radio channel between the tags and the readers compete in the system performance, which are very much depending on the major parameters of the reader antennas. Based on a model of these effects, it is possible to optimize this performance, in terms of detection and localization coverage.
