Abstract

A new method for compnting the far field of a possibIy shaped or deformed reflector antenna based on a sampling representation of the radiation integral is presented. Using a projection technique the required samples can be efficiently computed using a two-dimensional fast Fourier transform (FFT), whereas the radiated field is reconstructed via standard sampling expansion. Numerical examples and computation time analysis are reported showing the effectivenesosf the approach particularly for deformed reflectors and/or plane-cnt field evaluation.
