Abstract :
This paper presents a high-efficiency 2.45 GHz rectenna which can harvest low input RF power effectively. An antenna with a simple structure and high gain is directly matched to the rectifying circuit which eliminates the low-pass filter between the antenna and rectifying circuit. The measured peak gain of the antenna is 8 dBi. The rectenna efficiency can reach 50% with input power of 0 dBm.
