This paper is dedicated to investigate impact of the usage of different waveforms on the efficiency of wireless power transfer (WPT) to a commercially available energy harvesting device. The investigation is done at sub-GHz frequencies in laboratory conditions. RF energy harvesting device - Powercast P2110B is used for radiofrequency (RF) to direct current (DC) conversion. Four different waveforms are studied: single-tone, multi-tone with low PAPR, random and chaotic oscillations. During the experiments the comparison of average transmitted RF power to average received RF power at harvesting device input is done. Moreover, conversion of the average transmitted and received power at the output of harvesting device into DC power is analyzed.
