Abstract
To overcome the low-efficiency and limited working
range of the existing RF energy harvesting (EH) systems for the
wireless Internet-of-Things (IoT) sensors, a novel reconfigurable
system is proposed with integrated hill-climbing, maximum
power point tracking (MPPT) function for wide input power from
−22 to 4 dBm. A conceptual linear model with high accuracy
is also proposed to analyze the rectifier efficiency for MPPT
operations. The rectifier with o ff-chip matching is designed
with a patch antenna
