Abstract :
An alternate technique for the analysis of far field antenna patterns from near field measurements. This technique uses near field information to determine the far field using Fourier transform. Radiation from a planar aperture using asymptotic evaluation of aperture radiation field and Fourier transform is done. Sampling method is discussed at length to optimize the near zone data points. Exact far field has been computed and was compared to the transformed field of the near zone data.
