Zusammenfassung: | Disclosed is an array antenna having improved isolation characteristics. The disclosed antenna comprises: a plurality of radiators arranged at a predetermined distance apart from each other; a plurality of cut regions formed by cutting a portion of each of the plurality of radiators that overlaps with a virtual line set in a direction parallel to the arrangement direction of the radiators; and a plurality of resistors arranged for each of the plurality of cut regions. The disclosed array antenna may have good isolation characteristics by minimizing influence between the radiators and has an advantage of maintaining good isolation characteristics even when the isolation distance between the radiators is shortened.
L'invention divulgue une antenne réseau ayant de meilleures caractéristiques d'isolation. L'antenne divulguée comprend : une pluralité d'éléments rayonnants agencés à une distance prédéterminée les uns des autres; une pluralité de régions découpées formées par découpe d'une partie de chaque élément rayonnant de la pluralité d'éléments rayonnants qui chevauche une ligne virtuelle définie dans une direction parallèle à la direction d'agencement des éléments rayonnants; et une pluralité de résistances agencées pour chaque région découpée de la pluralité de régions découpées. L'antenne réseau divulguée peut présenter de bonnes caractéristiques d'isolation en réduisant à un minimum l'influence entre les éléments rayonnants et présente l'avantage de maintenir de bonnes caractéristiques d'isolation même lorsque la distance d'isolation entre les éléments rayonnants est raccourcie.
개선된 격리도 특성을 가지는 배열 안테나가 개시된다. 개시된 안테나는 소정 거리 이격되어 배치되는 다수의 방사체; 상기 방사체의 배열 방향과 평행한 방향으로 설정된 가상 라인과 오버랩되는 부분을 상기 다수의 방사체별로 절개하여 형성되는 다수의 절개 영역; 상기 다수의 절개 영역 각각에 대해 배치되는 다수의 저항을 포함한다. 개시된 배열 안테나는 방사체간 영향이 최소화되어 양호한 격리도 특성을 가질 수 있으며, 방사체간 이격 거리가 짧아지더라도 양호한 격리도 특성을 유지할 수 있는 장점이 있다. |
