An Experimental Investigation of the Radiation Patterns of Electromagnetic Horn Antennas

Abstract

A systematized set of radiation patterns of rectangular electromagnetic horn antennas have been measured and are shown as a function of electric and magnetic plane flare angles and radial length of the horn. A total of two hundred and fifty patterns are included for representative flare angles from zero to 50°, and radial lengths from zero to fifty wavelengths. This set of patterns reveals many characteristic properties which may serve as a guide in the design of electromagnetic horn antennas.
