Abstract :
A dual-band design of reflectarray antennas for the RFID applications operated at 0.9 and 2.4 GHz is presented. In this design, the fields radiated from the antenna will focus in the near-zone of array aperture. Numerical investigations on the radiation characteristics of this reflectarray, as well as an experimental validation, are presented to demonstrate its feasibility.
