Abstract
A compact dual-band planar wireless power transfer (WPT) system is presented in this paper. The planar structure is set to be 30-by-30 sq. mm to make it suitable for the Internet of Things and implantable medical devices applications. Furthermore, the system operates on two distinct frequencies, 0.9 GHz and 1.8 GHz, providing the potential for both data and power transmission. The desired resonances are achieved by varying the design parameters. Finally, the planar WPT with a 13 mm transfer distance reaches a PTE of 74% at 0.9 GHz and 66% at 1.8 GHz. Moreover, the influence of misalignment on the planar WPT is assessed, revealing the system's resilience to displacement within specific ranges at two frequencies.
