In this work, the wireless power transfer system employing nested open loop ring resonators at the ground plane is proposed. In the suggested design both the transmitter and the receiver are symmetric. The forward‐facing view contains the transmission line. The ground plane contains number of 33 open loop ring resonators which are nested together. The system has a size of 40 × 40 mm2 with a transmission distance of 15 mm. The proposed design is investigated in two cases with and without the loading capacitor. Comparisons between the resonance frequency and the power transfer efficiency of the proposed design with and without the loading capacitor are presented. The coupled resonator system achieved an efficiency of 97% at 1.35 GHz while the system with the loading capacitor achieved an efficiency of 98.8% at 1 GHz. The proposed system is designed, simulated, and measured.

“…DGSs are the incisions that are merged on the lower surface of the substrate. The setting of DGS shapes below the feed line is presented variation in the prevalence of the waves along the line improving some characteristics in the circuit [18][19][20][21][22][23][24][25], and [4][5][6]. Inductors and capacitors attached to DGSs are requested for modern RF/Microwave for performing filtering characteristics through small designs [18], [19].…”

“…However, the semi H-pattern accomplishes an enhanced efficiency of around 73 % with the board size is 21 × 21 mm 2 at a 25 mm perpendicular distance [26]. The authors in [24] present a unique model that includes two combined C-shaped resonators with an efficient coupling of 69 % at a 1.5 cm vertical distance. Though, the prototype size is 2.5 cm × 2.5 cm to permits the transmission of the power wirelessly.…”

In this work, a compact structure employing complementary split ring resonator defected ground structure (CSRR-DGS) and loaded with a chip capacitor for wireless power transfer (WPT) applications is suggested and discussed. The CSRR is loaded with a surface mounted (SMD) capacitor for miniaturization purposes.The proposed design is analyzed by J-inverters for verifications. The values of the extracted J-inverters for the proposed arrangement are calculated based on the mutual coupling among the transmitter (TX) and the receiver (RX). The prototype is fabricated and confirmed for validations. The model is designed at a center frequency of 500 MHz. The complete design has a total size of 25 × 25 m 2 . The proposed design achieves a coupling efficiency of about 97 % at a transmission distance of 16 mm. Good agreements among the electromagnetic (EM) simulation and the measurements have been attained. The suggested design is appropriate for short range WPT applications.

“…Placement of DGS resonators under the transmission line introduces changes in the propagation of the waves along the line enhancing some parameters in the circuit. Moreover, new materials like the artificial materials can be used to improve the characteristics of the microwave planar circuits like filters [7] and antennas [8] and also to be suitable for transmission of the high data rate. This technique can be used to improve the performance of the WPT systems.…”

“…The H-shaped DGS WPT system has a size of 20 × 20 mm 2 and an efficiency of 68% at distance of 13 mm while the semi-H-shaped DGS WPT system has an efficiency of 73% at a transmission distance of 25 mm and the total size of the system is 21 × 21 mm 2 . In [8], the authors propose a new structure which contains two compact C-shaped resonators allowing the transmission of the power without cables through 15 mm distance between the transmitter and the receiver with an efficiency of 69%. However, the total system size is 25 × 25 mm 2 .…”

In this article, a new wireless power transfer (WPT) design is proposed for improving the efficiency of the system. The suggested system contains two spiral defected ground structure (DGS) resonators coupled back-toback. A band-pass filter is then to be designed for the wireless power to be transferred from the transmitter unit to the receiver unit. The DGS resonators are loaded through chip capacitors for miniaturization. The proposed structures are fabricated and tested. The proposed system has the highest efficiency of 97.7% at a transmission distance of 10 mm which is suitable for biomedical applications. Both simulated and experimental results are in good concurrence.
