Recent Advancements in Defected Ground Structure Based Near-Field Wireless Power Transfer Systems
The defected ground structure (DGS) technique enables miniaturization of the
resonator which leads to the development of the compact near-field wireless
power transfer (WPT) systems. In general, numerous challenges are inherent in
the design of the DGS-based WPT systems and, hence, appropriate trade-offs for
achieving optimal performance are required. Furthermore, the design
advancements have led to the development of the DGS-based multi-band WPT
systems to fulfill the needs of simultaneous data and power transfer. The
innovations in the DGS-based WPT systems have also resulted in the definition
of more commonly used figures-of-merit for the benchmarking of various
performance metrics. The literature is replete with the design schemes to
address one or more associated design challenges and successful WPT system
realizations with enhanced performance. With this in mind, this paper touches
upon the DGS-based WPTs developments and presents a concise report on the
current state-of-the-art and future directions.Comment: 12 pages, 11 figures, to be published in IEEE Acces
