Contribution au développement de modèles orientés système pour les antennes des communications Ultra Large Bande

Abstract : Ultra-Wideband is a promising technology for future short-range wireless communications with high data rates as well as radar and localisation. In this thesis, we are interested to UWB antennas and especially to their characterization and modelization. The characteristics of the UWB antennas are emphasized compared to antennas of the narrow band systems. We show that a relevant representation is to model the UWB antennas as linear and time invariant systems. We propose new definitions for the transfer functions and associated impulse responses. The “system” characterization is completed adding parametric modelization to reduce the number of required data and also to integrate the models of the antennas in various simulation systems. The proposed modelings are issued to electromagnetic simulations and measurement in the frequency domain. Moreover, several UWB antennas are considered.
