This work 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, signals’ spectral properties, 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. The study is performed in four parts: theoretical analysis of WPT technology, RF-DC converter prototyping, an experimental survey on RF-DC conversion efficiency and experimental study on WPT performance. The work results are partly developed within research projects “Radio Frequency Power Transmission for Wireless Sensor Network Use” and “Advanced Techniques for Wireless Power Transfer” and published in 13 scientific articles. The Thesis consists of four chapters, 63 figures, 10 tables, and 3 appendices. The total number of pages is 85, not including appendices. The Bibliography contains 91 references.
