| Abstract | ||||
| 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 m2. 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. | ||||
