METHOD FOR CONTROLLING THE TUNING TO A COMMUNICATIONS FREQUENCY OF AN ANTENNA CONNECTED TO A COMPONENT DESIGNED FOR CONTACTLESS COMMUNICATION AND CORRESPONDING SYSTEM
Abstract:
A system includes an antenna, and a contactless component for receiving and/or transmitting information via the antenna according to a contactless communications protocol. An inductive-capacitive network is connected between the antenna and the contactless component and includes a configurable filter for filtering electromagnetic interference. A processor modifies an impedance of the configurable filter for filtering electromagnetic interference to control frequency tuning of the antenna.
Abstract(Chinese):

一种系统包括天线和非接触式组件，用于根据非接触通信协议经由天线接收和/或发送信息。 电感电容网络连接在天线和非接触元件之间，并且包括用于滤波电磁干扰的可配置滤波器。 处理器修改可配置滤波器的阻抗，以过滤电磁干扰，以控制天线的频率调谐。
