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.
