Abstract

This paper presents an approach to signal excitation specially designed to improve the DC power obtained in a RF to DC converter and consequently its RF-DC efficiency conversion. In this sense a multisine signal is used as the excitation, and it is proved either theoretically, by simulations and by measurements, that a multisine signal with 0° phase relationship between the tones can give better DC values in an energy harvester, when compared with a single tone excitation with the same input average power.
