Abstract
Wireless power transmission, which can convert RF energy to DC power, has been studied several decades and become an interesting topic for energy transmission. The rectenna is one of the most important components for a microwave power transmission. This paper focuses on developing new rectenna for 900MHz at low incident power.

The rectenna is designed by voltage doubler structure and slot antenna. The rectenna uses schottky diode HSMS-2852, super capacitor and boost converter TPS61200 to get regularly output voltage. The new rectenna has been developed to rectify RF energy to dc power with about 40% efficiency at 900MHz when the incident RF power density is 0dBm. The proposed slot antenna has 18dB return loss at 900MHz. The results of this paper show that the rectenna is possible to apply for wireless power transmission.
