A Wireless Power Transfer Application Using CSRR

This paper presents a wireless power transfer application with electrical coupling. The proposed structure uses a Complementary Split Ring Resonator (CSRR) as defected ground structure (D GS). The top layer is very simple with a single open-ended transmission line. A simulation with loss has been done in this letter, and the operating frequency of the designed transmission line is 0.94 GHz, with a dimension of 50x50 mm2. The efficiency reaches as high as 85% at a transmission distance of 15 mm.
