A Comprehensive Review of Wideband Rectennas and Design Challenges
Radio frequency energy harvesting (RFEH) presents a sustainable and maintenance-free solution for powering wireless sensor networks and Internet of Things (IoT) devices by converting ambient RF signals into usable electrical power. The previously leading single-band RFEH technology was limited to one frequency only, posing a risk of unproductive operation when that frequency is unavailable. This paper examines and explores the different strategy of wideband RFEH system and provides an overview of the latest advancements in wideband rectennas. The paper incorporates a comprehensive categorization of wideband rectennas that outlines the antenna type, rectifier topology, diode type, impedance matching network, and power conversion efficiency employed in each wideband rectenna design. The incorporation of a detailed table including various parametric study enriches the review with empirical data, thereby enhancing its practical significance. The discussion of design challenges, rectifier topologies, and methods to boost power conversion efficiency addresses crucial technical aspects of wideband rectifiers, filling gaps in current research literature. By combining a thorough examination of design challenges and various methodologies, the paper proves to be a valuable asset for enhancing the effectiveness and adaptability of wideband rectifiers in RFEH applications.
期刊介绍：
The International Journal of Communication Systems provides a forum for R&D, open to researchers from all types of institutions and organisations worldwide, aimed at the increasingly important area of communication technology. The Journal''s emphasis is particularly on the issues impacting behaviour at the system, service and management levels. Published twelve times a year, it provides coverage of advances that have a significant potential to impact the immense technical and commercial opportunities in the communications sector. The International Journal of Communication Systems strives to select a balance of contributions that promotes technical innovation allied to practical relevance across the range of system types and issues.
The Journal addresses both public communication systems (Telecommunication, mobile, Internet, and Cable TV) and private systems (Intranets, enterprise networks, LANs, MANs, WANs). The following key areas and issues are regularly covered:
-Transmission/Switching/Distribution technologies (ATM, SDH, TCP/IP, routers, DSL, cable modems, VoD, VoIP, WDM, etc.)
-System control, network/service management
-Network and Internet protocols and standards
-Client-server, distributed and Web-based communication systems
-Broadband and multimedia systems and applications, with a focus on increased service variety and interactivity
-Trials of advanced systems and services; their implementation and evaluation
-Novel concepts and improvements in technique; their theoretical basis and performance analysis using measurement/testing, modelling and simulation
-Performance evaluation issues and methods.
