Title (EN) CONICAL CORRUGATED MICROWAVE FEED HORN
(FR) ANTENNE-CORNET RAYONNANT D'ALIMENTATION EN MICRO-ONDES ONDULEE ET CONIQUE
Abstract: front page image
(EN)A conical corrugated microwave feed horn (10). A conical flare section (60) is formed at the aperture (20) of the feed horn (10) and a second smooth cylindrical section (200, 210) is formed at the throat (30) of the feed horn (10). The conical flare section (60) is formed with two regions (70, 220) whereby region (70) is a corrugated conical region formed at the aperture (20) and having a plurality of slots (70) formed parallel to the central axis (204) of the feed horn (10). Each slot (70) in the plurality of slots (70) has an inner surface (250) closest to the central axis (204) of the feed horn and an outer surface (240) furthest from the central axis (204). The first slot (70A) adjacent the smooth conical region (220) has first and second formed lips (280, 290) on the terminating end. The last slot (70C) of the plurality of slots (70) at the aperture (20) of the feed horn (10) has the terminating end of the inner surface (240B) extending in length beyond the length of the outer surface (240C).
(FR)On décrit une antenne-cornet rayonnante ondulée et conique. Un segment d'ouverture conique (60) est disposé à l'entrée (20) de ce cornet (10) et un deuxième segment cylindrique lisse (200, 210) est formé au niveau de sa gorge (30). Le segment d'ouverture conique (60) comprend deux zones (70, 220), l'une (70), conique et ondulée, prévue à l'entrée (20) et dotée de plusieurs rainures (70) parallèles à l'axe central (204) du cornet rayonnant (10). Chaque rainure (70) présente une surface interne (250) proche de cet axe central (204) et une surface externe (240) qui en est plus éloignée. La première rainure (70A), adjacente à la zone conique lisse (220), présente deux lèvres (280, 290) constituant son extrémité. La dernière rainure (70C) placée à l'entrée (20) du cornet rayonnant (10), présente une surface interne (240B) dont la longueur dépasse celle de la surface externe (240C).
