Advanced Reconfigurability of Frequency-diverse Radiators for both Localization and Powering

In this work an effective and feasible procedure for real-time focusing of Frequency Diverse Arrays (FDAs) is proposed, to be exploited for intentional far-field Wireless Power Transfer (WPT) applications. The array layout relies on a circular symmetric transmitting architecture where the frequency diversity is applied by rings. This solution represents one of the best in terms of focused area dimension and therefore able to support precise powering applications. Through a software control able to manage the multi-frequency excitation a preliminary localization phase for the collection of targets data position is performed, followed by a precise and energy-aware powering phase, enabling a real-time and capillary WPT system.
