Contribution au co-design et à la co-intégration de réseaux d’antennes actives multi-bandes pour systèmes de radionavigation par satellite

Abstract : This work takesplace in the context of developingelectronic systems for communications equipment, localization or monitoringequipment with a high integration density. The deployment of these systems must also meet a growing demand for flexibility in terms of frequencies, power or coverage. The frequency flexibility can be simultaneous with multiband devices or selective by reconfiguring the frequency band. The power flexibility enables to minimize consumption of the system and the coverage flexibility to direct the beam to the target to optimize the budget link or otherwise protect a source of noise. The increase in efficiency and compactness passes through the combination of elementary functions (LNA / filter / antenna) that reduces interconnect floors and considering the interactions between the different elements. The primary objective of this project is to develop a co-design methodology of the antenna with the associated circuits (filters and LNA) to achieve optimal performances (radiation,efficiency, ...) with an integrated and compact device.
