—In this paper, an overview of antenna design for passive
radio frequency identification (RFID) tags is presented. We
discuss various requirements of such designs, outline a generic design
process including range measurement techniques and concentrate
on one practical application: RFID tag for box tracking in
warehouses. A loaded meander antenna design for this application
is described and its various practical aspects such as sensitivity to
fabrication process and box content are analyzed. Modeling and
simulation results are also presented which are in good agreement
with measurement data.
