Energy Harvesting with 2.45 GHz Rectenna for urban application

International audienceThis paper describes the conception of a 2.45 GHz rectenna for energy harvesting application. Electromagnetic simulations have been carried out using Computer Simulation Technology software. The enhancement of the simulated output DC voltage is obtained with resonant circuit and Cockroft Walton boost (containing four zero bias diodes) for a sinusoidal input voltage. The simulated proposed rectenna with single zero-bias diode and RF-DC boosting circuit have been realized and measured inside an anechoic chamber. The behavior of measured plots is in accordance with the simulated ones. The simulated RF-DC boosting rectenna enhanced the output DC voltage up to 140 mV for 1 μW/cm 2 power density
