Abstract

This paper reports an inkjet-printed radiation pattern reconfigurable (RPR) receiving antenna for wireless power transfer application with 2.45 GHz frequency. Conductive ink EGaIn and polyimide are employed as the radiator and the flexible substrate, respectively. The geometrical parameters of the proposed antenna are optimized to obtain a favorable matching of impedance, and the S11 at 2.45 GHz is −22.71 dB, with good agreement between the simulation and measurement results. The reconfigurable characteristics of the pattern are achieved by the flexible antenna bent conformally, while the trends of S11 are investigated under various bending radii of curvature. The performance of the RPR flexible antenna receiving RF energy under multi-angle incidences is verified experimentally.
