  • Abstract
    This paper presents the development of a dual-band rectenna optimized to convert far-field RF energy to DC voltage at very low received power. Implemented on a standard FR4 substrate with commercially off-the-shelf (COTS) devices, the RF harvester provides a rectified voltage of 1V for a combined power of -19.5dBm at 915MHz and -25dBm at 2.44GHz. The remote powering of a clock is demonstrated, and the rectenna yields a power efficiency of 27%.
