摘要

本文用谱域方法估计了具有余弦基座型激励的孔径天线的近场。在空间域中，由孔径平面上的场分布得到任意平面上的平面波谱。光谱的傅里叶反变换使近区场的评估以及孔径场的重建成为可能。

Prediction of near field of an aperture antenna having cosine over pedestal type of excitation for EMI estimation

This paper presents an estimation of the near field of an aperture antenna having a cosine over pedestal type of excitation from the spectral domain approach. The plane wave spectrum at any plane is found from the field distribution at the aperture plane in the spatial domain. The inverse Fourier transform of the spectrum enables an evaluation of the near zone field as well as the reconstruction of the aperture field.
