Abstract

Near Field Communication (NFC) applied with resonant coupling would lead to an innovative improvements such as power transfer efficiency and robustness, which can be most suitable for medical applications. However, there are several technical issues of the conventional NFC system that makes it difficult to apply resonant coupling. One of the critical issues is that the system performance becomes excessively sensitive to impedance matching and bandwidth of its antenna. In this paper, we propose a novel high-Q NFC system that overcomes the limitations of applying resonant coupling to conventional NFC system. As a result, the high-Q NFC system showed remarkable improvement in energy efficiency. Moreover, the high-Q NFC system showed perfect compatibility with conventional NFC system, while it quadrupled the power transmission efficiency.
