| Abstract |
This paper presents multi-band and multi-location radio frequency (RF) survey for ambient energy harvesting. As an alternative to costly spectrum analyzers, the survey was conducted using software defined radio for FM (88-108 MHz), cellular band (880 MHz) and Wi-Fi band (2.4 GHz). The power levels at three different locations in a tier-II smart city were recorded and plotted to get information on the available ambient RF power levels. A full wave voltage quadrupler circuit (2-stage Dickson rectifier) was implemented to act as a rectifier and a voltage booster. Two different types of antennae were used for capturing the ambient RF signals - wire antenna and capacitive loop antenna. No impedance matching circuitry was employed and the ambient RF signals were used to charge up a capacitor connected to the rectifier output. Capacitive loop antenna helped in achieving a peak capacitor voltage of 16 V and outperformed the simple wire antenna which provided a peak capacitor voltage of 13 V. The charged capacitor was also used to drive an LED. © 2019 IEEE. |
