The paper describes an intentional wireless power transfer procedure based on an augmented reconfigurability of time-modulated arrays. The standard switch control sequences choice is enriched by the presence of a reconfigurable feeding network: in this way, the novel additional capability of fundamental frequency beam steering is achieved, as well as a full control of the sideband radiation phenomenon, typical of these arrays. As a result, precise, real-time wireless powering to randomly distributed tags becomes straightforward. The effectiveness of the proposed agile reader/transmitter architecture, applied to a 5.8 GHz eight-element patch array, is demonstrated by resorting to an accurate nonlinear/ electromagnetic co-simulation approach.

Abstract
The paper describes an intentional wireless power transfer procedure based on an augmented reconfigurability of time-modulated arrays. The standard switch control sequences choice is enriched by the presence of a reconfigurable feeding network: in this way, the novel additional capability of fundamental frequency beam steering is achieved, as well as a full control of the sideband radiation phenomenon, typical of these arrays. As a result, precise, real-time wireless powering to randomly distributed tags becomes straightforward. The effectiveness of the proposed agile reader/transmitter architecture, applied to a 5.8 GHz eight-element patch array, is demonstrated by resorting to an accurate nonlinear/ electromagnetic co-simulation approach.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
