Abstract
An antenna arrangement for a chip card includes an antenna conductor structure that is formed from a surface conductor. The antenna conductor structure includes a dipole arrangement arranged on a card substrate and that has a first antenna strand and a second antenna strand. The antenna conductor structure includes a terminal arrangement connecting the antenna conductor structure to a chip and for forming a transponder including the antenna conductor structure and the chip. A surface of the card substrate is divided into a grasping zone for handling the chip card and a transponder zone for arranging the transponder in such a manner that the grasping zone extends beyond a center region of the substrate surface and at least one lateral edge of the grasping zone is formed by a lateral edge of the substrate surface.
