Abstract—In this paper, we investigated the effect of power combining
and delivering in multiinput and multioutput wireless energy
transmission systems, which consist of more than one transmitter
antennas as sources and more than one receiver antennas
as loads and repeaters. Theoretical expressions were developed to
model the system operation that can be in a large-scale wireless energy
network architecture. System characteristics, such as power
transfer between antennas, power losses induced in each antenna,
wireless efficiency, coil misalignment, and power fluctuation due
to the loss of frequency synchronization were examined by theory
and verified with experiments. Measurement results matched well
with the theory demonstrating the feasibility of combining and delivering
power with high efficiencies in large-scale wireless energy
transmission systems.
