Abstract :
Power transfer efficiency (PTE) of wireless power transfer (WPT) using near-field coupling of multi-antenna is numerically analyzed by using the scattering parameters after modeling the whole multi-antenna WPT system as a multi-port network. Because the multi-port scattering parameters can easily be measured by using a vector network analyzer and calculated by a full-wave numerical analysis, it is convenient to investigate the relationship between the PTE and the geometry of the multi-antenna WPT system, such as the relative position of the transmitting antenna and the receiving antennas, the geometry of antennas and copper loss in the antennas.
