Abstract
A near-field antenna based on a coplanar waveguide is provided. The antenna is configured to communicate with a targeted transponder from among a group of multiple adjacent transponders. The antenna may include a first ground plane, a second ground plane, a dielectric substrate, and a conductive strip. The first ground plane and the second ground plane extend along the dielectric substrate and the conductive strip extends between the first ground plane and the second ground plane such that first ground plane and the conductive strip define a first slot extending between the first ground plane and the conductive strip and the second ground plane define a second slot extending between the second conductive strip and the conductive strip. The first ground plane, the second ground plane, and the conductive strip are substantially coplanar. In other embodiments, a novel assembly of a ribbon guide and a near-field antenna is provided.
