| Abstract: | Efficient numerical analysis of dual-frequency stacked annular-ring microstrip antennas is presented. Galerkin' s method is applied in the Hankel transform domain to clerivc the. characteristic equation. The resonant frequencies are obtained by numerically solving the characteristic equation and compared with the experimental data available in the literature In addition to the rotenone frequencies , the far-zone radiation patterns are easily obtained from the Hankel transforms of the tangential electric field components on the surface of the upper substrate. Several numerical examples of the radiation patterns are presented. |
