Multi-tone Excitation Analysis in RF Energy Harvesters -Considerations and Limitations Shariati, N, Scott, J, Schreurs, D and Ghorbani, K 2018, 'Multi-tone Excitation Analysis in RF Energy Harvesters -Considerations and Limitations', IEEE Internet of Things Journal, vol. 5, no. 4, pp. 2804-2816. Document type: Journal Article Collection: Journal Articles Title Multi-tone Excitation Analysis in RF Energy Harvesters -Considerations and Limitations Author(s) Shariati, N Scott, J Schreurs, D Ghorbani, K Year 2018 Journal name IEEE Internet of Things Journal Volume number 5 Issue number 4 Start page 2804 End page 2816 Total pages 13 Publisher IEEE Abstract The effect of multi-tone excitation on the DC response of a voltage-doubler RF (radio frequency) energy harvester is analysed. Theoretical analysis as well as frequency and time domain simulations were conducted to clarify the findings. Measurements were also carried out to validate the results. The measured, simulations and theoretical results are in good agreement. This paper focuses on evaluating the performance of a voltage doubler rectifier under multi-tone excitation (input power is the same in the single-tone and multi-tone case). Based on time domain and harmonic balance simulations, theoretical and measurement analyses, it is evident that the application of multiple tones simultaneously within the matched frequency band and with the same average available power results in a lower average output DC power when compared with the single-tone case with the same input power. This trend is evident over a broad low input power range of -50 to -10 dBm (0.01-100 µW).
