Analysis of microstrip and Vivaldi antennas using a CG-FFT scheme that allows the study of finite dielectric sheets with arbitrary metallization on both sides
A conjugate-gradient-fast-Fourier-transform (CG-FFT) scheme to analyze finite dielectric sheets with arbitrary metallization on both sides is used to study microstrip and Vivaldi antennas. The system of integral equations is discretized by expanding the electric and magnetic currents in terms of rooftops and by testing the resulting fields using blade razor functions. The case of a small dipole embedded in a square dielectric sheet of side 0.1 lambda with epsilon = epsilon /sub 0/ is investigated. In addition, a comparison between computed and measured radiation pattern values for a Vivaldi antenna is presented. Discrepancies between the computed and measured values are attributed to the simple numerical model considered for the antenna feeding.<>
