Abstract
The one or more embodiments of the specification provide an antenna structure and a payment device. The antenna structure includes a flexible insulating film, the front and back surfaces of the flexible insulating film are etched with windings, the windings on the front and back surfaces are in series, and the windings form a conductor wire for constructing an antenna coil. The conductor wire is wound around multiple turns from inside to outside or from outside to inside to form the antenna coil. In addition, a conductive element for enhancing the conductive performance is arranged on the end pin of the antenna coil.
