It depends upon the radiation patterns of the used antennas. The relation between the radiation patterns and the correlation coefficient is worked out. Theoretical predictions are shown to have good agreement with the experiment.

An alternative approach based on approximate physical currents is shown to give good agreement for both radiation patterns and input impedances.

The case of an infinite ground plane is first examined, and then the concept of using a magnetic edge current as an equivalent source of diffraction on the limited size ground plane is introduced.

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 Palmitic Acid material or water like materials. 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 Palmitic Acid 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.
