This work presents a high efficiency, co-planar and low-complexity RF-to-dc rectifier of one diode, which is able to be directly connected, i.e., without a matching network, to a coplanar antenna, e.g., to a dipole or loop antenna. The rectifier was designed to optimally operate at 868 MHz and for low power input. Specifically, it presents 54.82% RF-to-dc efficiency for 20 dBm power input, while for −14.4 dBm the system is able− to supply continuously, i.e., with any boost converter, a backscatter sensor node with power consumption of 20 µW.
