МОDELING OF A VECTOR RADIATION PATTERN OF PARABOLIC REFLECTOR ANTENNA

Abstract

A new approach to a vector radiation pattern of parabolic reflector antenna calculation based on its reflector consideration as a no-planar end of circular waveguide and reflection coefficient calculation by invariant imbedding method, is developed. As a result, an expression for the distribution of the vector field at antenna aperture in multimode regime of excitation is obtained. The developed approach may be interpreted as a basic new step in the development of aperture antenna theory.
