The idea of this paper is to develop a moving resonant wireless power transfer (WPT) system capable of keeping the coupling factor, and thus the power transfer, invariable with respect to the reciprocal system sides positions. A typical scenario is the WPT to moving objects on a platform equipped with a sequence of coils underneath. If a single TX coil is active at a time, the receiver movement would...
The same antenna, designed to exploit its far-field properties for communication purposes, can be suitably configured for simultaneously realizing wireless power transfer via its near-field properties. In this paper we analyze the near-field behavior of a pair of closely coupled transmitting and receiving dual-band printed monopole antennas, suitable for cell phones applications. The proposed architecture...
