This work introduces a novel concept of Wireless Power Transmission (WPT) for indoor environments and applications. In the proposed system, WPT is combined with a passive, localization system the aim of which is to localize devices to be charged and activate the WPT radiators only in the areas of interest. This allows for the efficiently empowering electronic devices inside the buildings by embedding a grid of RF power radiators (i.e. patch antennas) into the floor. In particular, each unit-cell of the grid is composed by a patch antenna at 2.45 GHz surrounded by a 13.56 MHz coil connected to a HF RFID tag with localization purposes.

Abstract
This work introduces a novel concept of Wireless Power Transmission (WPT) for indoor environments and applications. In the proposed system, WPT is combined with a passive, localization system the aim of which is to localize devices to be charged and activate the WPT radiators only in the areas of interest. This allows for the efficiently empowering electronic devices inside the buildings by embedding a grid of RF power radiators (i.e. patch antennas) into the floor. In particular, each unit-cell of the grid is composed by a patch antenna at 2.45 GHz surrounded by a 13.56 MHz coil connected to a HF RFID tag with localization purposes.File in questo prodotto:
