ABSTRACT:
An antenna is disclosed that comprises a flexible printed circuit material having first and second halves that are joined by a fold section. A coil trace is on the first half and a coil trace is on the second half. The antenna further comprises a first jumper between coil traces. The flexible printed circuit material is folded along the fold section so that the first and second halves are disposed back-to-back. An apparatus for reading information from a transponder is also disclosed that comprises a reader having an antenna capable of transmitting and receiving signals from a transponder, with the reader using an antenna according to the present invention. A media storage system is also disclosed that comprises a plurality of transponders, each of which is disposed on a respective one of a plurality of data cartridges and transmits a data signal related to its data cartridge. The media storage system further comprises a cartridge access device internal to a system housing for retrieving and transporting the data cartridges, and a reader attached to the cartridge access device, the reader capable of receiving transmitted signals from and transmitting signals to the transponders. The reader comprises an antenna according to the present invention that is capable of receiving and transmitting signals.
