In this paper, an electric filed focus scheme based on phase adjustable microwave source is used to improve the power transmission efficiency. A microwave power transmission system is consisted of the microwave source, a transmitting antenna and a receiving antenna. Measurement results proved that when compared with the same phases condition, the output DC power of the receiving antenna is increased from 23.5W to 31.5W and the relative increment of power is 34% under the focal phase condition. In addition, the system-level MW-DC power transmission efficiency is increased by 2.7%.
