Abstract

An attempt is made to apply the method of moments (MoM) to large tapered slot antennas (TSA). Previous analyses of the current distribution on the conducting plates and the polarization current in the dielectric region suggested the use of an optimal unequal sectioning of the antenna. That sectioning helps to reduce the number of involved unknowns while improving the modelling of the slot geometry. Our numerical results are compared to experimental measurements, and large TSA proved to be efficient with respect to other analysis methods. Despite the amount of hardware resources used by this model, our algorithm is run on a desktop computer. Once again, the MoM shows its sharp accuracy in handling electromagnetic problems. © 2004 Wiley Periodicals, Inc.

## Abstract Recently a discrete Fourier transform–method of moments (DFT‐MoM) scheme was developed for fast analysis of electrically large rectangular planar dipole arrays, which has been shown to be very efficient in terms of number reduction of unknown variables and computational complexity. The
