Abstract—This paper discussed the design of a dual-band
harvester to efficiently handle a wide input power range while
addressing the failure voltage issue in conventional rectifiers by
operating a FET as a switch amongst low and high input powers.
Designed for the two ISM bands of 915 MHz and 2.4 GHz, it
achieved an RF-DC efficiency of more than 40 % over a wideranging
of input power from -11 dBm to 25 dBm and -4 dBm to 21
dBm as well as a maximum power efficiency of 72% at 11 dBm
and 67% at 15 dBm for the two respective bands, making it
appropriate for Wireless Power Transfer applications.
