Nisshinbo has developed rectifiers for Wireless Power Transfer that achieve high efficiency and high dynamic range with low threshold diodes. The prototype device consists of a dual loop antenna with high antenna gain (9.6 dBi), high radiation efficiency (97% @ 5.9 GHz), and a balanced double current rectifier for low output DC voltage. This antenna and rectifier are direct matched, without the need for an impedance-matching circuit, which achieves high efficiency. The measured rectification efficiency is 79 % at a frequency of 5.9 GHz, with an input power of 29 dBm, and output voltage of 6.1 V.
