Abstract

This paper presents the first demonstration of an ultra-miniature module combining with 13.56/6.78-MHz wireless charging receiving functions and types-A/B/F near-field communication (NFC) functions. In order to be able to embed this module into mobile terminals, the electrical and thermal designs are optimized and then the size is 14 × 26 × 1.86 mm. A simulation bench for verifying the efficiency of the wireless charging, performance of NFC by a wireless charging antenna, thermal design for embedding the module into a mobile terminal and EMI reduction of the wireless charging system are described.
