“…The existing solutions based on plug-in charging may not satisfy the transition to electric vehicles alone. Wireless charging, or wireless electric roads, are thought to be technologies that could help accelerate the adoption of electric vehicles [51]. Wireless charging is a way to transmit energy from one coil to the other coil without having a hard connection between the two [44].…”

This article is designed to demonstrate that electric roads are an affordable way to electrify all forms of road transport—not only cars, but also buses and trucks. Electric roads represent a way to power electric vehicles without relying solely on batteries. The idea is that when an electric vehicle reaches an electric road, it stops using power from the battery and instead uses power directly from the road itself. The primary challenge for electric vehicles is still the perception of a compromised quality of life in owning an electric vehicle due to a limited range compared with petrol and diesel cars, today. This paper introduces a new technology, currently experiencing rapid development, that can not only overcome range anxiety but make electric vehicles better, in terms of range, than petrol and diesel cars today. Furthermore, not only can this research help to arrange this, but it can also help, for the first time, to cost-effectively electrify heavy-duty transport, such as trucks and buses, which would be a huge breakthrough in terms of sustainability, as it is very important to start supplying electricity to heavy-duty vehicles. The case study provides a very hypothetical example of a trip with and without an electric road, covering a total of 26,011 km of highways and main roads. The results indicate that building electric roads is cheaper than many other alternatives. If a large battery is replaced with a smaller battery for each new vehicle sold, after 3 years, enough savings will be made to electrify all highways and main roads in Turkey. This paper can help transport operators and policymakers develop strategies to accelerate the adoption of electric vehicles by appropriately implementing electric road infrastructure.

“…As a result, this frequency has a lower efficiency than the other frequency at 0.28 GHz. The proposed work introduces the idea of using the resonator at the top layer for the WPT which is not formerly proposed in the lately published works [21][22][23][24][25][26][27][28][29][30]. The overall dimensions of the design are 20 × 20 mm 2 and the accomplished FoM are 0.2736 and 0.238, respectively using (8).…”

“…In [26], dual-mode inductors are used and implemented for dual-band WPT system, the system operated at 90 and 138 MHz with efficiencies of 70 and 69%, respectively. This study improved the performance of the DF-WPT by reducing the size and increasing the efficiencies compared to recently published works [21,22,[27][28][29][30]. In [29], the authors proposed and investigated the DF-WPT which operates at 0.3 and 0.9 GHz at a transmission distance of 10 mm using two interlaced and coupled C-shaped DGS at the ground plane.…”

“…This system has a size 35.8 mm × 20 mm and a figure of merit (FoM) of >1 at transmission distance of 40-44 mm. The authors in [22] introduced a WPT system for the industrials applications such as electric vehicles and tramways applications by using the particular transformer without ferromagnetic core supplied by a resonant inverter and loaded by mobile sources. In [23], a dual-band WPT system using two single loops DGS resonators is proposed.…”

“…Further, the control of the two frequencies is independent due to the isolation between the two resonators which easily allows the adjusting of the two frequencies. In addition, the proposed design operates at 0.28 and 0.49 GHz and discusses how to exploit the top layer as well the bottom layer which is not previously investigated in the recently published works [21][22][23][24][25][26][27][28][29][30].…”

This work introduces a novel design for high efficiency and compact size dual‐frequency wireless power transfer (DF‐WPT) systems. The proposed design is composed of two identical transmitting (Tx) and receiving (Rx) substrates. Each substrate has a microstrip feed line, a C‐shaped coupled resonator on the top layer and a spiral coupled defected ground structure on the bottom layer. The system is analysed using J‐inverters for the dual‐frequencies (DFs) operation. The measured results show that the proposed DF‐WPT system with a compact size of 20 × 20 mm2 is able to provide a stable WPT characteristic with total efficiencies of 91.2 and 79.4% at 0.28 and 0.49 GHz, respectively with a transmission distance of 6 mm. The proposed system achieved good agreements between the analytical design procedure, the circuit model, the electromagnetic simulations, and the measurements.

SummaryIn this paper, a noteworthy compact dual‐band wireless power transfer (DB‐WPT) system is presented and studied. This DB‐WPT system is proposed using a capacitively loaded interdigital capacitor which reduces the size of the whole system, lessens the number of the attached surface mount elements, and accomplishes high efficiencies. An interdigital capacitor is printed in the ground plane of the design and loaded with a chip capacitor to produce dual bands. The operation of the system is verified by fabricating the proposed DB‐WPT system, which shows measured coupling efficiencies of 96% and 98.8% at 0.53 and 1.1 GHz, respectively at a transfer space of 12 mm. The fabricated structure has dimensions of 13.5 mm × 20 mm. The results show good agreement between the circuit model and the measurements. The idea of this design makes it applicable for compact near‐field WPT applications.
