Abstract
Abstract—Conventional wireless power transfer systems consist
of a microwave power generator located at one place and
a microwave power receiver located at a distance. To realize
efficient power transfer, the system brought to resonance and
the coupled-antenna mode is optimized to reduce radiation into
surrounding space. In this scheme, moving or varying a receiver
results in a necessity of the difficult tuning the whole systems that
implies a complex and energy consuming feed-back structure.
We propose a new paradigm of wireless power delivery where
the whole system, including transmitter and receiver, is a united
microwave power generator. Instead of first converting DC or
50/60 Hz power into microwaves and then arranging a wireless
transfer link between two antennas, in our proposed scenario
microwave oscillations are directly generated at the receiver
location, eliminating the need for dynamical tuning of the system
impedances.
