Analysis of horn radiators having the complex form cross-section and aperture

V. F. Manoilov, V. V. Pavlyuk


An approach to the calculation of directional patterns and matching characteristics with free space of waveguide-horn radiators having the cross-section and aperture of complex form has been proposed. Solutions were obtained for rectangular and circular ridged radiators with due regard for the proper numbers of equivalent ridged waveguides in the known expressions for the reflection coefficient and directional patterns of open ends of waveguides having the simple (rectangular and circular) form. The possibility of using the obtained solutions for the practical calculations with the required accuracy at a much smaller computational complexity as compared with similar solutions has been shown.
