This paper presents a new application of dielectric resonator antenna in radio frequency identification system. A curved dual‐band dielectric resonator antenna for RFID applications is proposed. The tag antenna is designed to operate at 2.45 GHz (2.25‐ 2.55 GHz) and 5.8 GHz (5.65‐ 5.95 GHz) bands. The radiation characteristics of the tag antenna in free space are investigated. The radar cross sections under different loads are obtained. The effect of curvature on the tag antenna performance is explained. Two examples areconsidered. In the first example, the tag antenna ismounted on cylindrical bottle filled with the Polyethylenematerial. The effect of the object properties on theradiation characteristics and the radar cross section isinvestigated. In the second example, the tag antenna ismounted on spherical bottle filled with the Polyethylenematerial. The radiation and backscattering characteristicsare calculated. The Finite Element Method (FEM) is usedfor simulation and the Finite Integration Technique (FIT)is used to verify the simulated results
