Abstract

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 are considered. In the first example, the tag
antenna is mounted on cylindrical bottle filled with the
Polyethylene material. The effect of the object properties on
the radiation characteristics and the radar cross section is
investigated. In the second example, the tag antenna is
mounted on spherical bottle filled with the Polyethylene
material. The radiation and backscattering characteristics
are calculated. The Finite Element Method (FEM) is used
for simulation and the Finite Integration Technique (FIT) is
used to verify the simulated results.
