New compact design for short range wireless power transmission at 1GHz using H-slot resonators

摘要

In this paper, we present a new design for short range wireless power transfer using two compact size H-slot resonators. These quasi-lumped element resonators can transfer power through electromagnetic resonant coupling with high efficiency and compact structures. The proposed design enables us to achieve power transfer efficiency of 85% at distance 5 mm. The new proposed design has been fabricated and measured to operate at 1 GHz. Measurements have shown consistency with simulation results and theoretical studies.
