Abstract (en)
[origin: WO9425996A1] According to the invention, each elementary cell comprises two resonators (R1, R2). Each resonator (R1, R2) comprises a microband (MR1, MR2) of which one branch (L1, L2) is used for coupling and has one end (e1, e2) connected to frame (22) and a capacitor (C1, C2) which is also connected to frame (22). The cells are connected directly to each other. Application to the fabrication of pass-band filters, particularly in the FM band.
