[Rectenna multi-bandes pour des applications micro-ondes]
Cet article présente une nouvelle rectenna (antenne + redresseur) multi-bandes utilisable pour la récupération d'énergie électromagnétique à bord de satellites géostationnaires. L'objectif est de récupérer l'énergie électromagnétique rayonnée par les antennes placées à bord du satellite. L'énergie ainsi récupérée est alors utilisée pour alimenter des capteurs autonomes sans fil. Les résultats expérimentaux montrent que cette rectenna récupère, avec une bonne efficacité, l'énergie électromagnétique à trois fréquences, qui correspondent aux fréquences de résonance de l'élément rayonnant de la rectenna.
This paper reports a multiband rectenna (rectifier + antenna) suitable for the electromagnetic energy harvesting of the spill-over loss of microwave antennas placed on board of geostationary satellites. Such rectenna is used for powering autonomous wireless sensors for satellite health monitoring. The topology of the rectenna is presented. The experimental results demonstrate that the proposed compact rectenna can harvest efficiently the incident electromagnetic energy at three different frequencies that are close to the resonant frequencies of the cross-dipoles implemented in the antenna array.
