1 INTRODUCTION
1.1 Purpose and Scope
This application note is intended to support RF-related design–in of Micore reader ICs. 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 used
antenna designs.
