This paper proposes four newly-designed antenna configurations for the applications of short-distance wireless power transfer. The antennas are developed from a traditional circular loop antenna, which have a structural feature in common that all of them are in enclosed shape. Four proposed designs aim to improve the transfer efficiency. In this work, the transmitting antenna faces to the receiving antenna with a distance of 12 cm in the wireless power transfer system. Results show that two of them have better performance of transferring power than the other two and the conventional design.
