摘要：

This paper is proposed the efficiency improvement in wireless power transfer system is applied sensor device in loT system. The study and design of the metamaterials structure to he applied with antennas in wireless power transfer (WPT) system at 2.45 GHz (ISM band) are performed to improved efficiency of power transfer. The two types of metamaterial are applied to the wireless power transfer. 1)The Artificial Magnetic Conductor (AMC) type, it is designed to be placed behind the antenna of transmission part. The Microstrip antenna is used in this paper. This AMC is use as the in-phase reflector to increase radiation intensity and efficiency of the transmit antenna. 2) Metamaterials structure type of Multiple Split-Ring Resonators (MSRR) that have negative refraction index is placed between the transmit antenna and the receiving antenna. This feature of the structure reduces the evanescence of the electromagnetic wave. From the results, it is found that the metamaterials can he optimized for both antennas in a wireless power transfer system at 2.45 GHz and improved the efficiency of wireless power transfer system
