Application of dielectric and ТЕМ horns in phased antenna arrays

Abstract

The effect of the dielectric layer and metal horns on the characteristics of waveguide phased antenna arrays was studied using the finite element method. The geometric dimensions of the horns were optimized for better matching of the antenna array when scanning at an angle θ. Graphs illustrating the dependence of beam width and directivity on the number of elements in one side of the square array are plotted. Radiation patterns of the antenna array are plotted for different numbers of elements on one side of it.
