Abstract
Based on simulated and experimental results, this letter discusses the interests of a novel reconfigurable rectenna structure designed for rectification of UHF wireless energy. Several circuit topologies are combined in order to obtain high RF-to-dc energy conversion efficiency over a wide input-power range. Improvements are proposed in order to overcome the need for a maximum power point tracking (MPPT) device and to ensure high efficiency over a wide load-value range.
