Abstract (en)

[origin: EP0290844A2] In a directional antenna, whose radiation pattern can be shaped using simple means, outside the horn emitter (2), in its radiation pattern, there is arranged at least one conductive disc (4), which has an opening that is at least as large as that of the horn aperture, the effect of this conductive disc (4) depending on the shape of the radiation pattern of the opening cross-section, and on the distance of the disc (4) from the horn aperture. <IMAGE>
