Abstract

This letter presents a novel full-system communication quality analysis of a wireless power transfer (WPT) and near-field communication (NFC) system. The analysis is conducted via a thoroughly verified broadband equivalent circuit (EC) model of a WPT and NFC system prototype. Such an EC model can accelerate the iterative system design process for systems with interoperating or coexisting WPT and NFC interfaces. The EC model is verified by measurements of a prototype. EC model and measurements agree excellently by comparing impedance parameters, single-sided frequency spectra, and the signal constellation diagram of the NFC tag-to-reader communication signal. The NFC communication quality analysis shows a severe impairment of the NFC tag-to-reader communication by the WPT system.
