Abstract
(EN)
An antenna device comprises: a first antenna; a second antenna; and a plurality of single decoupling network circuits DN_1-DN_n which electromagnetically connect the first antenna and second antenna and remove a self-interference signal, wherein a multi-stage decoupling network circuit in which the DN_1-DN_n are dependent-connected can be configured such that a Y21 parameter of the multi-stage decoupling network circuit becomes equal to or lower than a predetermined value on frequencies f_1-f_n, respectively.
(FR)
L'invention concerne un dispositif d'antenne comprenant : une première antenne ; une seconde antenne ; et une pluralité de circuits de réseau de découplage unique DN_1-DN_n qui connectent électromagnétiquement la première antenne et la seconde antenne et éliminent un signal d'auto-interférence, un circuit de réseau de découplage à étages multiples dans lequel les DN_1-DN_n sont connectés en fonction peut être configuré de telle sorte qu'un paramètre Y21 du circuit de réseau de découplage à étages multiples devient inférieur ou égal à une valeur prédéterminée sur les fréquences f_1-f_n, respectivement.
(KO)
안테나 장치는 제 1 안테나; 제 2 안테나; 및 상기 제 1 안테나 및 상기 제 2 안테나를 전자기적으로 연결하여 자기간섭 신호를 제거하는 복수의 단일 디커플링 네트워크 회로들 DN_1 ~ DN_n 을 포함하고, DN_1 ~ DN_n이 종속 연결된 다단 디커플링 네트워크 회로는 주파수 f_1 ~ f_n 각각에서 상기 다단 디커플링 네트워크 회로의 Y21 파라미터를 일정값 이하로 만들도록 설정될 수 있다.
