The finite-difference time-domain (FDTD) method is used toanalyze circular dielectric rod antenna excited by conducting waveguide. Two dimensional cylindrical FDTD algorithm is applied for rotationally symmetric structure. UPML is used for the cylindrical structure. Radiation patterns and reflection coefficients of this structure am obtained and compared with those available in the literature. Antenna characteristics am also determined for different rod length, tapering angle, hole position, and diameter.
