| Abstract |
The present study deals with the design of a dual-band wireless power transfer (WPT) system using Defected ground structure (DGS) model resonators. The most important factor will be achieving high conversion efficiency while keeping its structural dimensions small. To improve transmission efficiency and minimize return losses and insensitivity to mismatch between resonators at their resonance frequencies, we introduce a gap in the ground layer. For the proposed system, the transmission power efficiency at frequencies of 330 and 770 MHz is 92.5\% and 84.6\%, respectively, the simulation results from both CST and ADS software are closely aligned. Also, the figure of merit (FoM) derived from the simulation results is 0.78 and 0.72 at respective resonance frequencies. |
