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.INDEX TERMS Coupling, defected ground structure (DGS), multi-band, resonator, Q factor, single-band, wireless power transfer (WPT).

“…In this context, there has been a growing interest of researchers in the development of the WPT systems. In particular, there is an increasing interest in near-field WPTs as they have a broad application area, such as implantable medical devices, 3 consumer electronics, 4 low-power sensors, 5,6 radio-frequency identification, 7,8 wireless body area network, 9 and so forth. In general, there are three distinct techniques to achieve near-field WPT, namely, capacitive, 10 inductive, 11 and magnetic resonance.…”

“…The DGS technique, on the other hand, has some definite advantages over the conventional coil-based approach such as miniaturization, fabrication and design simplicity, multi-band operation, and so forth, and, therefore it could be a better alternative to solve these constraints associated with the coil-type WPTs. 15 It is also accepted that different DGS shapes lead to varying results and, therefore, authors have explored different DGS shapes, such as plus, 5 dual-E, 8 H, 14 triangle, 16 square, 17 and circle. 18 In general, there are two methods, namely, cascaded 17 and multi-mode 19 techniques, available to develop the multi-band WPT systems.…”

The potential advantages of simultaneous wireless information and power transfer (SWIPT) applications have necessitated innovations in the associated circuits and systems. This article, therefore, explores the concept of cascaded resonators, for the first time, in the design of a compact-size defected ground structure (DGS)-based tri-band wireless power transfer (WPT) system to advance the SWIPT technology. The design is augmented with a systematic design procedure that is preceded by the development of a new double-elliptic DGS-based tri-band resonator. Initially, the analysis of the proposed resonator is performed to identify the impact of defect size on the bandwidth. Subsequently, the resonators are cascaded to achieve a tri-band functionality and then utilized in the design of WPT. The designed WPT operates at 0.3, 0.5, and 0.9 GHz, and takes a compact size of 39 × 13 mm 2 . The measurement of the realized WPT with the transmitter and receiver, separated by the distance of 10 mm, provides an efficiency of around 60% at all three bands with the figure of merit values of about 0.5. Furthermore, the proposed design achieves a bandwidth of more than 3 MHz bandwidth at the frequencies corresponding to communication standards.
