Abstract EN
A metamaterial-inspired efficient electrically small antenna is proposed, firstly.
And then several improving power transfer efficiency (PTE) methods for wireless power transfer (WPT) systems composed of the proposed antenna in the radiating near-field region are investigated.
Method one is using a proposed antenna as a power retriever.
This WPT system consisted of three proposed antennas: a transmitter, a receiver, and a retriever.
The system is fed by only one power source.
At a fixed distance from receiver to transmitter, the distance between the transmitter and the retriever is turned to maximize power transfer from the transmitter to the receiver.
Method two is using two proposed antennas as transmitters and one antenna as receiver.
The receiver is placed between the two transmitters.
In this system, two power sources are used to feed the two transmitters, respectively.
By adjusting the phase difference between the two feeding sources, the maximum PTE can be obtained at the optimal phase difference.
Using the same configuration as method two, method three, where the maximum PTE can be increased by regulating the voltage (or power) ratio of the two feeding sources, is proposed.
In addition, we combine the proposed methods to construct another two schemes, which improve the PTE at different extent than classical WPT system.
