Wireless Power Transfer Procedure via Hybrid Frequency Diversity

This paper investigates the versatility of Frequency Diverse Arrays (FDAs) for smart transmission of power. A linear frequency distribution is compared to a logarithmic one in case of a series-fed multi-finger planar array operating at 24 GHz. Both the localization and the powering of potential targets placed in the scanning plane can be effectively performed with an FDA: however, the retrieval of the target position calls for a linear arrangement of the frequencies, whereas a logarithmic one is suitable for a precise transmission of the power. The envisaged scenario needs for an agile software control of the radiating system but pave the way to future capillary transfer of power.
