Antennes agiles reconfigurables optiquement dans le domaine millimétrique avec l’intégration de matériaux à changement de phase

Abstract : This thesis address the design and realization of optically reconfigurable antenna systems in the millimeter wave domain integrating phase change materials (PCM). The principle of agility is based on the changes in resistivity of PCM, which have the property of changing from an insulating (amorphous) to a conductive (crystalline) state in a reversible, repetitive and non-volatile (bistable) manner by the application of a thermal, electrical or optical external stimuli. We have designed and studied several frequency and polarization reconfigurable antennas operating around 30 GHz integrating GeTe as an agile element. Thus, we propose alternative solutions to conventional switching technologies for reconfigurability functions.
