Title (EN) PHASE SHIFTER AND COMMUNICATION DEVICE COMPRISING SAME
(FR) DÉPHASEUR ET DISPOSITIF DE COMMUNICATION COMPRENANT CE DERNIER
(KO) 위상 변위기 및 이를 포함하는 통신 장치
Abstract:
(EN) This phase shifter comprises: a fixed line having one end connected to an input terminal, to which a wireless signal is input, and the other end connected to one of a plurality of output terminals, to which the wireless signal is output, and having a coupling point formed between the one end and the other end; a plurality of transmission lines which are spaced apart from each other over the fixed line and formed in an arc shape and have both ends thereof respectively connected to the different output terminals; and a coupling changer which is formed at the coupling point and changes the phase of the wireless signal by subjecting each of the plurality of transmission lines to coupling feeding while rotating within a set angle range. The plurality of transmission lines each have a plurality of slits extending inwards from the outside of the transmission lines.
(FR) La présente invention concerne un déphaseur comprenant : une ligne fixe dont une extrémité est connectée à une borne d'entrée, à laquelle un signal sans fil est appliqué, et l'autre extrémité est connectée à une borne d'une pluralité de bornes de sortie, à laquelle le signal sans fil est délivré, et qui possède un point de couplage formé entre lesdites extrémités; une pluralité de lignes de transmission espacées les unes des autres sur la ligne fixe et formées arquées, les deux extrémités desdites lignes de transmission étant respectivement connectées aux différentes bornes de sortie; et un changeur de couplage formé au niveau du point de couplage et qui modifie la phase du signal sans fil en soumettant chaque ligne de la pluralité de lignes de transmission à un couplage d'alimentation tout en tournant dans une plage d'angle définie. La pluralité de lignes de transmission présentent chacune une pluralité de fentes partant de l'extérieur des lignes de transmission vers l'intérieur.
(KO) 위상 변위기는 무선 신호가 입력되는 입력단에 일단이 연결되고, 상기 무선신호가 출력되는 복수의 출력단 중 하나에 타단이 연결되며, 상기 일단과 상기 타단 사이에 커플링 포인트가 형성되는 고정 선로, 상기 고정 선로의 상측에서 상호 이격되어 형성되며, 호(arc) 형상으로 이루어져 양단이 서로 다른 출력단에 각각 연결되는 복수의 전송 선로 및 상기 커플링 포인트에 형성되며, 설정된 각도 범위내에서 회전하면서 상기 복수의 전송 선로를 각각 커플링 급전시켜 상기 무선 신호의 위상을 가변시키는 커플링 가변기를 포함한다. 상기 복수의 전송 선로 각각에는 상기 전송 선로의 외부 방향에서 내부 방향으로 연장되는 복수개의 슬릿(slit)들이 형성된다.
