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.
