A numerical analysis of various dielectric resonator antennas (DRAs): simple (single element) and complex shape configurations (stacked and embedded resonators) with different excitations (dipole, coaxial probe, slot‐coupled microstrip line) using a time‐harmonic surface finite element method (SFEM) is presented. Numerical results have been compared with those obtained using a volume time‐domain finite‐element method (TDFEM) and experiments. Measurements on return loss and radiation field patterns show a good agreement with computed ones. Copyright © 2000 John Wiley & Sons, Ltd.
