The Loading Effect of Proximity Contactless Smart Card. Incidences of Impedance of the Shunt Regulator.

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.
