Reader antenna for use with rfid transponder

Abstract

The invention relates to a reader antenna for use with radio frequency identification (RF ID) transponders. A reader and the transponder are connected to one another via a wireless interface. It is the object of the invention to provide a reader antenna for RFID systems whose transmission range is increased in comparison with a transmission range in a normal air environment without metallic influence with otherwise the same electrical and electromagnetic parameters. The reader antenna in accordance with the invention is provided with an antenna which is formed with a coil having at least one winding. The coil lies on a side of a carrier remote from a transponder and the carrier is made exclusively of a soft magnetic material.
