Evaluation of the Kirchhoff integral which arises in the far-field computation of radiation from large aperture antennas frequently causes computational difficulty. This communication illustrates the utility of evaluating the integral in terms of end-point contributions. The special case of a pyramidal horn-reflector antenna is considered.
