On the basis of the equation of the Fresnel-Kirchhoff scalar diffraction field,it is shown that theimpulse responses of parallel-fed aperture antennas of arbitrary configuration with arbitrary apertureamplitude distributions and those of end-fed rectangular aperture antennas with arbitrary apertureamplitude distributions can all be expressed by the aperture amplitude distributions,and that theimpulse responses of rectangular aperture antennas with separable aperture distributions and those ofcircular aperture antennas with circularly symmetric distributions are special cases of the abovegeneral ones.
