N2 - Energy harvesting (EH) becomes one of the important alternative technologies to provide energy for low power electronic devices. The implementation of an independent wireless charging node is mainly depending on the efficient design of the RF-DC rectifier. In this study, a high-efficient and wideband CPW rectifier is proposed. In order to achieve broadband operation, the T-matching circuit is employed. The arms of the matching circuit are composed of reactive LC components to suppress the nonlinearities of the rectification element i.e diode. The rectifier performance is studied and the simulation results are validated with the experimental measurements. The rectifier shows more than 40% efficiency over the band from 0.8 to 2.2 GHz which is sufficient to intercept 400 µW if the incident power is 1 mW. The peak efficiency is 63% at 920 MHz ISM band. Several measurements were taken to demonstrate the agreement between the simulated and measured output results.
