摘要：

This paper presents estimation of near field of an aperture antenna having triangular type tapered aperture illumination, for EMI estimation. To estimate near field of the antenna at different distances away from its aperture, use has been made of FFT technique to find spatial field from spectral distributions. The field at the aperture is reconstructed to provide validity of the computation algorithm. The near field data given are useful for EMI estimation of aperture antenna with triangular type tapered aperture illumination. The computation technique can be utilised to find field distribution at any distance away from the antenna aperture over any planar or sperical surface for EMI hazards.
