Key Components of Rectenna System: A Comprehensive Survey

In this paper, a comprehensive survey on the key components of a rectenna system, including antenna configurations, rectifier configurations, impedance matching networks, and RF filter, is outlined. Due to increased applications, the rectenna has occupied a unique place in the RF and microwave engineering. For the last few decades, the research on the rectenna design is focused-on to improve the power conversion efficiency, compatibility and to reduce the design complexity. The main objective of the proposed paper is (i) to accommodate the key design requirements of the rectenna; (ii) highlight the specifications and the possible configurations of the rectenna elements as diode, rectifier, and input source; and (iii) present an inclusive survey of the remarkable research carried out and obtained results.
