Abstract :
The "loading effect" in RFID systems is well known and has already been described in several papers. The inclusion of a shunt regulator in a smart card with a well defined resistance variation law can improve and/or reduce the loading effect. The goal of this paper is to present a new approach to obtaining and defining this law of variation.
