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.
