Abstract :
On the basis of Kirchhoff technique the computer software for calculation the amplitude and phase characteristics of radiation from an open-ended circular waveguide and conical horn in near field and intermediate field zones has been produced. The dependencies of electromagnetic fields on the axial distance from the antenna are analysed and the far field zone distance boundary is specified for small waveguide apertures.
