Radio frequency energy harvesting (RFEH) presents a sustainable and maintenance-freesolution for powering wireless sensornetworks and Internet of Things (IoT) devices by converting ambient RF signals into usable electrical power. The previouslyleading single-bandRFEH technology was limited to one frequency only, posing a risk of unproductive operation when thatfrequency is unavailable. This paper examines and explores the different strategy of wideband RFEH system and provides anoverview of the latest advancements in wideband rectennas. The paper incorporates a comprehensive categorization of widebandrectennas that outlines the antenna type, rectifier topology, diode type, impedance matching network, and power conversion efficiencyemployed in each wideband rectenna design. The incorporation of a detailed table including various parametric study enrichesthe review with empirical data, thereby enhancing its practical significance. The discussion of design challenges, rectifiertopologies, and methods to boost power conversion efficiency addresses crucial technical aspects of wideband rectifiers, fillinggaps in current research literature. By combining a thorough examination of design challenges and various methodologies, thepaper proves to be a valuable asset for enhancing the effectiveness and adaptability of wideband rectifiers in RFEH applications.
