Abstract. As interest in sustainable and energy conscious technologies continues to rise, wireless power transfer (WPT) has become an important component in advancing green innovation by minimizing transmission losses and enabling contact-free power delivery. This work investigates the optimization at 5.82 GHz. The study examines how antenna performance can be improved through variations in substrate type, substrate thickness and slot geometry. A set of simulation models was developed using Fused Quartz and Polypropylene substrates with multiple thickness options, as well as a dual layer configuration in which the secondary substrate’s thickness was varied. Additional performance gains were explored through several slot arrangements integrated into the patch. The optimized design, featuring a dual-substrate structure and a centrally positioned slot placed nearer to the feedline, achieved an efficiency of 95%. These findings support the advancement of high efficiency WPT systems that contribute to border sustainable and environmentally conscious energy solutions.
