Abstract :
This paper presents a small loop antenna and high output voltage rectifier in wide frequency band for RF(radio frequency) energy harvesting of FM broadcasting signals. Target input power level of -20dBm is used to design a loop antenna for DC output voltage-boosting. The RF energy harvesting on suburb area provides 924mV DC output for a single rectenna and 1.72V DC output for twin rectennas by receiving several FM broadcasting signals simultaneously.
