A 35GHz circular-polarized rectenna with high efficiency is proposed in this paper. The rectifier is designed at 35GHz using Schottky diode of MA4E1310. Two Schottky diode is series-parallel connected in the rectifying circuit, which has a measured rectifying efficiency of 54% with a 600 Ω when the received power is 63mW. The proposed rectifier is printed on the bottom side of antenna. The antenna is simulated by the full wave EM analysis software of HFSS and the rectifying circuit is simulated by using the ADS software. A four element rectenna array is designed with rotating array and the circular patch antenna fed by the coupling slot is employed to receive power form free space with a high gain of 12 dB. The low profile and easy integration of the proposed rectenna will be used for reference in the field of millimeter wave wireless energy transmission.(MMPT)
