Abstract :
A method combining the `generalised telegraphist´s equations¿ with a mode-matching technique is proposed well suited for the calculation of short horn antennas. Curves are given for the optimum flare angle, gain and reflection coefficient of a plane sectoral horn excited in the TEM mode. It is shown, that for short horns the aperture-throat interactions cannot be neglected.
