Abstract: A radiating element (10) having a continuous aperture substantially greater than one half the center frequency wavelength for use in an electronically scanned phased array antenna operating in the range of 94 GHz. The new radiating element comprises a ferrite block (12) having a radiating aperture which measures 5 lambda by 5 lambda in contrast to the conventional discrete radiating element which measures one-half lambda by one-half lambda. A tapered magnetization (see lines 22) is applied to the continuous aperture ferrite block (12). The degree of phase shift can be varied by adjusting the slope of the tapered magnetization. This permits scanning of the continuous aperture pattern. When a plurality of such continuous aperture subarrays is used to form an antenna array (80 or 100), provision is made to adjust the phase at the center of each continuous aperture subarray with respect to the phase of the adjacent subarrays, thereby allowing scanning of the entire pattern of the phased array antenna (100).

Abstract: Un élément de radiation (1) ayant une ouverture continue sensiblement plus grande qu'une moitié de la longueur d'onde de la fréquence centrale est utilisé dans un réseau d'antennes en phase à exploration électronique fonctionnant dans la gamme de 94 GHz. Le nouvel élément de radiation comprend un bloc en ferrite (12) ayant une ouverture de radiation qui mesure de 5 lambda en 5 lambda contrairement à l'élément de radiation conventionnel qui lui mesure d'un demi lambda en demi lambda. Une magnétisation conique (voir lignes 22) est appliquée au bloc de ferrite à ouverture continue (12). Le degré de déphasage peut être modifié en ajustant la pente de la magnétisation conique. Ceci permet l'exploration de la configuration de l'ouverture continue. Lorsqu'une pluralité de ces sous-réseaux à ouverture continue est utilisée pour former un réseau d'antennes (80 ou 100), on prévoit d'ajuster la phase au centre de chaque sous-réseau à ouverture continue par rapport à la phase des sous-réseaux adjacents, permettant ainsi l'exploration de toute la configuration du réseau d'antennes en phase (100).
