RF Powering of Autonomous Wireless Sensor Network Nodes
Summary of the Doctoral Thesis
Jānis Eidaks, Riga Technical University, Latvia
The Thesis is dedicated to the experimental study of RF powering of autonomous wireless sensor network nodes. The impact of powering signal properties on the RF-DC conversion efficiency and wireless power transfer performance is investigated. The impact of average input power level, peak-to-average power ratio (PAPR) level, different modulation types, spectral properties of signals, numbers of sub-carriers, and bandwidth are examined. The most popular RF-DC converter topologies and off-the-shelf solutions in the sub-GHz frequency range have been studied in detail.
