发明名称 Resistive assessment of the coupling coefficient of an electromagnetic transponder
摘要 <p>The method involves evaluating a relation between a current coupling factor of an electromagnetic transponder (2) with a terminal and an optimum coupling position with a value of a resistor. Discordance of an oscillating circuit of the transponder is provoked if the relation is higher than an upper threshold or equal to unit, where the oscillating circuit is constituted by an inductor (L2) and a capacitor (C2). Reduction in consumption of the oscillating circuit and a rectifying circuit of the transponder is provoked if the relation is less than another threshold or equal to the unit. An independent claim is also included for an electromagnetic transponder comprising an oscillating circuit.</p>
