The present invention relates to a wireless communication device, such as a transponder,
that has a plurality of antennas for multi-frequency usage. The wireless communication
device comprises a control system, communication electronics, memory, and the aforementioned
antennas. A wireless communication device having a pole antenna may be used with
one or more loop conductor antennas to achieve the desired operating frequencies.
A wireless communication device having a dipole antenna may be coupled across a
loop conductor antenna to provide different loop conductor configurations depending
on the frequency.
