Zusammenfassung:The present invention relates to an RF filter assembly for an antenna and, particularly, comprises: a plurality of band pass filters (BPFs); a filter board which is arranged to be stacked on the front surface of a main board and which mediate the coupling of the band pass filters for the front surface of the main board; low pass filters (LPFs) intaglio- or embossed-printed on front surface of the filter board; and an air layer formation pad arranged between the filter board and the band pass filters to form a predetermined air layer between the front surface of the filter board and rear surfaces of the band pass filters, and thus the overall performance of a filter product can be improved by minimizing insertion loss of a filter. La présente invention concerne un ensemble filtre RF pour une antenne et, en particulier, comprend : une pluralité de filtres passe-bande (BPF) ; une plaque de filtre qui est agencée pour être empilée sur la surface avant d'une carte principale et qui assure la médiation du couplage des filtres passe-bande pour la surface avant de la carte principale ; des filtres passe-bas (LPF) en creux ou en relief imprimé sur la surface avant de la plaque de filtre ; et un tampon de formation de couche d'air disposé entre la plaque de filtre et les filtres passe-bande pour former une couche d'air prédéterminée entre la surface avant de la plaque de filtre et les surfaces arrière des filtres passe-bande, et, par conséquent, la performance globale d'un produit de filtre peut être améliorée en réduisant au minimum la perte d'insertion d'un filtre. 본 발명은 안테나용 RF 필터 조립체에 관한 것으로서, 특히, 다수의 대역통과필터(BPF, Band Pass Filter), 메인 보드의 전면에 적층 배치되고, 상기 메인 보드의 전면에 대한 상기 대역통과필터의 결합을 매개하는 필터 보드, 상기 필터 보드의 전면에 음각 또는 양각 인쇄된 대역저지필터(LPF, Low Pass Filter) 및 상기 필터 보드와 상기 대역통과필터 사이에 배치되어 상기 필터 보드의 전면과 상기 대역통과필터의 배면 사이에 소정의 에어층을 형성하는 에어층 형성 패드를 포함함으로써, 필터의 삽입 손실을 최소화하여 필터 제품의 전체적인 성능을 향상시킬 수 있는 이점을 제공한다.
