Abstract
The amplitude and phase patterns of corrugated feed horns are predicted in the near-field region by means of a spherical-mode-expansion method which has been previously applied only in the far field. Excellent agreement has been observed with experimental patterns, and typical results for horns with flare semiangles of 12° and 70° are described.Keywords
