Design of a Triple Band Wireless Power Transfer (TB-WPT) system for Multiple Applications

In this paper, a triple band wireless power transfer (TB-WPT) system is presented using coupled spirals defected ground structures (Ss-DGSs) band stop filter (BSF). The simulated efficiencies are 98 %, 99 %, and 89 % at 0.26 GHz, 0.37 GHz, and 0.56 GHz, respectively. The suggested work has a size of 30×15mm
²
with a transmission distance of 9 mm. Due to its compact size and satisfactory performance, the design can be useful for modern wireless communication technology.
