A Comprehensive Analysis, Design, and Experimental Evaluation of Single-Loop Polygonal Slotted RF Resonators and WPT Systems

A thorough analysis of slotted ground plane (SGP)-based resonators designed for wireless power transfer (WPT) applications is reported in this paper. For the first time, some new findings that relate a resonator and WPT performance metrics to slot shape, quality factor (Q), radiation loss are presented very comprehensive manner. As case study, single-loop polygonal shape was considered carry out all analyses investigations. It has been identified no impact on and, hence, developed WPT. Instead, hugely dependent Q regulated by chosen area. These allow conceptualization systematic systems development design schemes readily realizable, they also enable significant improvement efficiency (PTE). The prototypes conforming industrial, scientific, medical frequency bands show an enhancement PTE extent 11% during measurements. proposed approach important steps advancing state-of-the-art radio-frequency WPTs. In essence, potential reinvigorate stagnated SGP-based so as facilitate requirements low-power applications.
