A correction to the available formula for the GTD near-field patterns of conical horns
TLDR
An error in the geometrical theory of diffraction (GTD) near-field analysis of a conical horn published earlier is pointed out in this paper, and the correct expression for the near field patterns for the conical Horn is presented.Abstract:
An error in the geometrical theory of diffraction (GTD) near-field analysis of a conical horn published earlier is pointed out. This error is corrected, and the correct expression for the near-field patterns for the conical horn is presented. Computations based on the corrected formulas correlate better with results based on measurement as well as aperture integration technique [4].read more
