dc.description.abstract | This study reports, for the first time, the use of coupled-line-based impedance matching in wireless power transfer(WPT) system. The transmitter and receiver of the WPT system are realised by microstrip feed line and symmetric coupled lineat the top plane. The ground plane is realised with triangular-shaped defect along with the excitation slot mounted by anexternal capacitor. The defect in the ground plane and the external capacitor regulate the resonant frequency and also enableminiaturisation of the WPT system. The design is augmented with a systematic analytical approach for impedance matching anda simplified design procedure for the WPT system. A novel equivalent circuit model consisting of parallel LC network andcoupled lines is also developed for the evaluation of the proposed WPT system design technique. A prototype of the systemoperating at 300 MHz developed on Rogers RO4350B substrate achieves a peak efficiency of 80% at a transmission distance of17 mm. An excellent agreement between the measured and the electromagnetic simulated results is a testament of therobustness of the proposed design technique. Furthermore, evaluation of the commonly used WPT-related figure of merit showssignificant enhancement when compared to the existing state of the art | en_US |
