A method and apparatus for providing power to e.g., a chargeable device via a radio frequency link. In one aspect, a method of providing power to a chargeable device via radio frequency link comprises generating a substantially un-modulated signal. The method further comprises radiating a substantially un-modulated radio frequency (RF) signal to the chargeable device via a transmit antenna based on the substantially un-modulated signal. The method further comprises powering or charging the chargeable device with power delivered by the substantially un-modulated RF signal.
L'invention concerne un procédé et un système d'alimentation d'un dispositif chargeable, par exemple, par l'intermédiaire d'une liaison radiofréquence. Dans un mode de réalisation, le procédé d'alimentation d'un dispositif chargeable par l'intermédiaire d'une liaison radiofréquence consiste à créer un signal essentiellement non modulé. Le procédé selon l'invention consiste par ailleurs à appliquer un signal radiofréquence essentiellement non modulé (RF) au dispositif chargeable par l'intermédiaire d'une antenne de transmission, sur la base du signal essentiellement non modulé. Le procédé selon l'invention consiste par ailleurs à alimenter ou à charger le dispositif chargeable avec de l'énergie fournie par le signal radiofréquence essentiellement non modulé.
