Abstract

Abstract : Viability of a conformal single‐layer monopole antenna is studied for a wall‐embedded tag in an ultra‐wideband (UWB) suitcase localisation application based on impulse radio UWB. The performance of the embedded antenna is simulated and confirmed experimentally in real‐time localisation (RTL) experiments carried out in a cluttered laboratory environment. Evaluation in the main planes shows average suitcase positioning error around 8 cm for worst‐case conditions. RTL tests are made when the suitcase is empty, when it is filled with common travelling items and also when it is shadowed by a second suitcase. A vector network analyser‐based measurement set‐up is used for target localisation error evaluation. Additionally, the same tests are repeated using portable commercial time‐domain transceivers with similar results.
