APPLICATION OF FRESNEL ZONE THEORY TO MICROWAVE ANTENNA DESIGN

Abstract

Some fundamental formulas are derived which are corrections to geometrical optics for radiation from bounded wavefronts. These formulas apply in both the near and far field, in focal and caustic regions, and in lit, twilight, and dark zones. Applications are made to improving the gain of a spherical reflector and the analysis of (generally unwanted) focussing of spillover energy in microwave systems.
