This paper describes the design and the optimization of a rectenna in ISM band, dedicated to wirelessly supplying RFID's sensors, to replace or recharge existing batteries. The circuit is based on a double voltage rectifier designed and optimized at 2.45GHz with ADS software. We detail a new methodology to design and optimize a rectenna circuit. As a result, excellent performance is achieved in terms...
