A Novel Design Method of RF Lens for Long-Range Wireless Power Transmission

This letter presents a novel radio frequency (RF) lens design method for long-range wireless power transmission. We theoretically evaluated the feasibility of the proposed method and fabricated the RF lens with the operating frequency of 30 GHz and the transmission distance of 4 m. Measurement resul...

Zusammenfassung:	This letter presents a novel radio frequency (RF) lens design method for long-range wireless power transmission. We theoretically evaluated the feasibility of the proposed method and fabricated the RF lens with the operating frequency of 30 GHz and the transmission distance of 4 m. Measurement results showed the transmission efficiency was significantly enhanced from 0.046% to 7.9%.
