Radiation from Conical Horns with Large Flare Angles

Radiationpatterns of conical horns with large flare angles excited in the TEnmode are calculated from a simple solution for horn modes using the vector diffraction formula. Radiation patterns are expressed in closed form when the half-flare angle is less than 30o. Patterns obtained by experiment show close agreement with calculated results.
