Abstract :
In this paper, the effect of curvature on circular polarization (CP) radiation characteristics of circularly-polarized dielectric resonator antenna (DRA) mounted on or embedded in cylindrical surfaces are studied. The antenna is designed for wireless applications at 9 GHz. In order to eliminate the effect of ground plane curvature on the CP characteristics by varying the DRA element height or embedded the DRA element in the curvature structure. The analysis using the finite element method (FEM) is applied. The results are validated by comparing with that calculated by the finite integration technique (FIT).
