Abstract

An inlay for a chip card. The inlay includes a module coupling antenna for inductively coupling to a chip module antenna of a chip module and a card reader coupling antenna for inductively coupling to a reader antenna of an external card reader. The card reader coupling antenna is electrically connected to the module coupling antenna. The inlay also includes a chip capacitor module that is electrically connected to the card reader coupling antenna for enabling the card reader coupling antenna to resonate at a predetermined frequency. The chip capacitor module includes at least one passive component for storing electrical energy. The at least one passive component has a capacitance within a range from 40 picofarads to 140 picofarads and a major area that is smaller than 2.6 square millimetres.
