This work introduces a wideband, significant RF-DC conversion efficiency and large DC voltage radio frequency (RF) voltage multiplier/doubler rectifier for energy harvesting (EH) systems utilizing ROG4003C material and Schottky diode. The input matching network is designed using π network and series resonance circuit. Two wideband rectifiers are designed the first one uses lumped inductors in the π network, and the second design employs distributed rectangular inductors. The π network is connected in series with a Schottky diode to compensate its capacitive reactance, diminish its impedance variation when the frequency or input power varies while the series resonance circuit is used to match the minimized variance to the source impedance (50 Ω). An HSMS2852-based rectifier prototype is tested for verification, obtaining a bandwidth of 31.6 % from 720 to 1050 MHz with 68 ± 2 % at an input power of 3
