Abstract
A chip card includes a body of electrically insulating layers, one of which carries an open loop antenna having two ends. The body is equipped with a cavity for housing a micromodule adapted for connection to the antenna by two terminals. The micromodule includes an insulating substrate carrying, on a first side, a semiconductor component, and on a second side, several electrical contact pads. Two of the contact pads are disposed in a strip running through a center region of the substrate. The terminals are connected to the two contact pads through the substrate, and the two pads are respectively connected to ends of the antenna.
