Recherche des caractéristiques optimales d'antennes multi-capteurs pour les systèmes MIMO

Abstract : MIMO technology is an attractive solution to come up to the increase of the data transfer rate due to the development of the multimedia services in wireless
communication systems. It promises a linear increase of data transfer rate in function of the antennas number at the transmitter and at the receiver by exploiting the antenna network diversity and the multi-path propagation. This technology, already used to increase data transfer rate in WLAN network, meets some difficulties in mobile telephony. In fact, it is not easy to implement multiple antennas on a ground plane whose dimensions are compatible with a mobile phone while preserving good performances. Closeness of elements generates coupling inducing power loss and diagram modifications.

This thesis presents the design of an antenna with two radiating elements for mobile phone following by a study of MIMO systems for mobile telephony. The
conception of a capacity simulator based on a complete propagation model allowed to compare antennas and their characteristics in urban cellular environment in the UMTS band.
