Modélisation statistique d'antennes dans leurs environnements

Abstract : STATISTICAL MODELING OF ANTENNAS IN THEIR CLOSE ENVIRONMENTS The last decade has shown a strong evolution of wireless communications through the development of a variety of applications and standards. However the increasing interest for these applications is leading to spectrum resources saturation. Dynamic spectrum allocation is one of the possible solutions contemplated to improve the spectrum utilization. In a Cognitive Radio context, the need of a complete knowledge of the propagation process in the spectral and spatial domains is essential. However, and this is a much less recognized and highlighted feature, the role and the performance of terminals is critical. The increasing complexity of terminals capabilities and functionalities make them more than ever difficult to assess in a multiple technologies context. The present work deals with the study of interactions between antennas and their close environments for two types of wireless applications: mobile phone and Ultra Wide Band high data rate communications. Antennas key performances indicators have been defined and then studied statistically through several simulated and measured configurations to illustrate the modeling methodology.
