More Information
Summary:An antenna coil, in particular for a contactless smart card, includes coil turns formed of thin conductor tracks having first and second ends. The first end of a respective one of the conductor tracks is electrically conductively connected to the second end of an adjacent one of the conductor tracks. The conductor tracks include first and last conductor tracks, and the first end of the first conductor track and the second end of the last conductor track form coil connections. The conductor tracks are disposed in parallel on a flexible, non-conductive carrier strip. The carrier strip has bends and forms a polygon containing the connected ends of the conductor tracks. The bends are guided through approximately 180 DEG , and the coil turns lie approximately in the same plane.
