In this paper we present the design of high efficiency low power rectifier for microwave energy harvesting. The proposed circuit is based on a voltage booster formed by a voltage doubler type Latour structure. The circuit topology including parasitic elements and microstrip lines has been studied and optimized for high efficiency energy conversion dedicated to low input power operations (below-10dBm). Measurement results show 21% and 38% RF-DC conversion efficiencies for, respectively,-20dBm and-10dBm input power for 10KΩ resistor load at 850MHz. Experimental performances of the rectifier are in good agreement with the simulated ones.
