1 INTRODUCTION
This application note is intended to support RF-related design–in of the MF RC500 MIFARE® reader IC. The
aim is to provide the required understanding of the MIFARE® RF interface (ISO 14443A) to design
application specific antennas and matching circuits to achieve the best performance for a communication
with a contactless MIFARE® card. This paper shall give a background on the system’s RF part and an
overview on the procedure how to design and tune antennas for standard applications. Two different
antenna and matching concepts are explained in detail as well as examples for the antenna design itself.
Furthermore, the complete tuning procedure is described. As part of the Annex, the interested reader will find
a detailed theoretical description of the RF interface.
