Étude d’une matrice agile rayonnante à pixels élaborés en métamatériaux maitrise de concepts, réalisation de prototypes et caractérisation

Abstract : This PhD thesis is dedicated to the study and the development of a novel agile antenna system called ‘Agile Radiating Matrix with Metamaterials Pixels’. This system is formed by a planar matrix which is composed by an association of jointed electromagnetic pixels. The pixel design is inspired from the electromagnetic band gap antenna and it is surrounded by metallic walls. These pixels are fed by means of several beam forming networks.The intensive theoretical study made on the matrix antenna, showed several electromagnetic performances concerning the low mutual coupling, the great beam steering for high scanning angles and the elimination of grating lobes. Three manufactured prototypes are presented in order to experimentally validate the matrix performances and to respond to some application requirements.
