Abstract :
A fast generalized algorithm for the analysis of multilayered patch antennas is presented based on the 3-D FDFD (Frequency Domain Finite Difference) method in conjunction with the asymptotic waveform evaluation (AWE) technique. In the AWE technique, the electric field strength at the input ports is expanded in a Taylor series around a frequency within the desired frequency band, and the coefficients of the Taylor series are matched via the Pade approximation to a rational function. Using the rational function, the electric field strengths at the input are obtained at any frequency within the desired frequency band, which is used to calculated the S parameter. A good agreement between the numerical results and the reported data is observed
