Numerical analysis of the near-field power transfer using multi-antennas is performed based on the scattering parameters for an equivalent circuit model of multi-port networks. The transfer power efficiency is derived by using the multi-port scattering parameters. Since the multi-port scattering parameters are easily measured by a vector network analyzer and calculated by a full-wave numerical analysis,...
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...
