Title:
帯域通過フィルタ、通信装置および共振器
Document Type and Number:
Japanese Patent JP6874915
Kind Code:
B2
Abstract:
A band pass filter (1) includes two resonators (8) and (10) including respectively linear conductors (9) and (11) disposed inside a dielectric substrate (2), and a pair of input-output lines (13) and (14) to which the two resonators (8) and (10) are connected in parallel. Both ends of the linear conductor (9) of the resonator (8) are left open. The resonator (10) includes vias (12A) and (12B) through which both ends of the linear conductor (11) of the resonator (10) are connected to a ground conductor (6) on a first surface (2A) of the dielectric substrate (2). The pair of input-output lines (13) and (14) include respectively vias (15A) and (15B) for connection to a ground conductor (7) that is disposed on a second surface (2B) of the dielectric substrate (2).
