Abstract :
With the great growth continuing in computers´ power that is associated with a big growth in the numerical algorithms for solving radiation problems, the finite difference time domain (FDTD) method has taken its chance to demonstrate its power in simplifying the sophisticated radiation problems. In this research, the FDTD method is used, with suitable absorbing boundary conditions (ABC) and feeding model, to solve the dielectric resonator antenna (DRA) problems both in two dimensions (2D) and three dimensions (3D) using different shapes of the antennas and different types of the feeding signals including transient signals. The resultant electric field strengths and radiation patterns are obtained for these cases
