Les drones sont attrayants pour de nombreux types d’industries, mais l’alimentation électrique limitée des batteries a empêché les drones de fonctionner pendant de longues heures. La transmission de puissance par micro-ondes (MPT) est l’une des technologies les plus prometteuses pour les libérer de cette limitation. Étant donné que, parmi plusieurs types de drones, le micro-drone a un temps de vol disponible plus court, il est raisonnable de fournir au micro-drone un accès au chargement sans fil avec un système MPT. Cependant, il n’existe pas de rectenna adaptée aux applications de chargement de micro-drones dans les études précédentes. Dans cet article, un système MPT pour micro-drone a été proposé en bande C, où un réseau de rectennes léger et compact avec une puissance de sortie de classe 20 W a été développé. Sous éclairage d'un faisceau plat de 203 mW/cm2 de densité de puissance, un réseau de rectennes à 16 éléments a été mesuré. La rectenne à 16 éléments a été formée à l'aide d'un substrat en nid d'abeille pour la légèreté et de diodes barrière Schottky GaAs pour un rendement élevé. Il pesait 37.5 g et mesurait 146.4 mm sur 146.4 mm. Il a produit 27.0 W de puissance continue à 19.0 V à 5.8 GHz lorsqu'une puissance radiofréquence de 280 W était générée par le magnétron verrouillé par injection et que 134 W étaient transmis à partir du réseau multiéléments de transmission. Le rapport puissance/poids était de 0.72 W/g. Le rendement de conversion de puissance était de 61.9 %. Ces chiffres ont surpassé les rectennas des études précédentes et conviennent à un système MPT pour micro-drone.

Abstract: Drones have been attractive for many kinds of industries, but limited power supply from batteries has impeded drones from being operated for longer hours. Microwave power transmission (MPT) is one of the most prospective technologies to release them from the limitation. Since, among several types of drones, micro-drone has shorter available flight time, it is reasonable to provide micro-drone with wireless charging access with an MPT system. However, there is no suitable rectenna for micro-drone charging applications in preceding studies. In this paper, an MPT system for micro-drone was proposed at C-band where a lightweight and compact rectenna array with 20-W class output power was developed. Under illumination of a flat-top beam with 203 mW/cm2 of power density, a 16-element rectenna array was measured. The 16-element rectenna was formed with the aid of a honeycomb substrate for lightness and GaAs Schottky barrier diodes for high output. It was 37.5 g in weight and 146.4 mm by 146.4 mm in size. It output 27.0 W of dc power at 19.0 V at 5.8 GHz when radio frequency power of 280 W was generated by the injection-locked magnetron and 134 W was transmitted from the transmitting phased array. The power-to-weight ratio was 0.72W/g. The power conversion efficiency was 61.9%. These numbers outperformed the rectennas in the preceding studies and are suitable for an MPT system to micro-drone.
