Effects of size mismatch in dual-function near-field antennas

Effective deployment of near-field wireless power transfer mechanisms requires the concurrent transfer of status and control data between the coupled terminals. The implementation of simultaneous data and power transfer requires an understanding of the interplay between the transfer efficiency and b...

The results suggest that equal-sized antennas provide a higher level of efficiency than with size mismatched antennas.
