Abstract :
The use of antenna arrays at emission and reception seems to be a good solution for future wireless systems in order to improve data rates and quality of service. The performance of these systems is very dependent on propagation channel. In this context, channel characterization and modeling are crucial In this paper, two antenna arrays are designed and calibrated at 3.5 GHz for high resolution MIMO (Multiple Input Multiple Output) channel sounding. This frequency band concerns Wireless Local Loop applications. Results obtained after the beam patterns calibration are presented. The importance of this work is shown by ESPRIT algorithm simulations for better multi-path parameters estimation. This work is needed to obtain accurate measurements results to model propagation channel.
