| Zusammenfassung: | An S-band quadrifilar antenna device having a stop band is disclosed. A quadrifilar antenna device according to an embodiment comprises: a quadrifilar antenna; and a feeding circuit for generating feeding signals from an input signal by using a coupler and a distributor, and outputting the feeding signals to the quadrifilar antenna, wherein the feeding circuit includes a filter disposed on at least one of a plurality of signal paths through which the input signal is transferred to the coupler and the distributor.
L'invention concerne un dispositif d'antenne quadrifilaire à bande S ayant une bande d'arrêt. Un dispositif d'antenne quadrifilaire selon un mode de réalisation comprend : une antenne quadrifilaire ; et un circuit d'alimentation pour générer des signaux d'alimentation à partir d'un signal d'entrée à l'aide d'un coupleur et d'un distributeur, et délivrant les signaux d'alimentation à l'antenne quadrifilaire, le circuit d'alimentation comprenant un filtre disposé sur au moins l'un d'une pluralité de trajets de signal à travers lesquels le signal d'entrée est transféré au coupleur et au distributeur.
차단 대역을 갖는 S-band 쿼드리필러 안테나 장치가 개시된다. 일 실시예에 따른 쿼드리필러 안테나 장치는 쿼드리필러 안테나와, 입력 신호를 커플러 및 분배기를 이용하여 급전 신호들로 생성하고, 상기 급전 신호들을 쿼드리 필러 안테나로 출력하는 급전 회로를 포함하고, 상기 급전 회로는 상기 입력 신호를 상기 커플러 및 분배기에 전달하기 위한 복수의 신호 경로들 중에서 적어도 하나의 경로 상에 배치되는 필터를 포함한다. |
