| Abstract: | The quadruple ridged horns having wide bandwidth, dual polarization and constant beamwidth properties and being often used as the feed of reflector antenna operating in an extra wide bandwidth are presented. The generalized scattering matrix of this kind of horn is calculated by using the hybrid method combining the finite element and the mode matching methods, and the far radiated field is computed using the double integral over the aperture. Finally the measured results are given, which are in good agreement with the calculated results. |
