Abstract

PURPOSE:To obtain a miniature and low insertion loss branching filter which can branch off the electromagnetic wave featuring a broad frequency band and propagating within the waveguide into a number of frequency components at one time, by connecting several units of the resonatorin parallel to the cross-section of the waveguide and setting the power nearly identical for each output waveguide. CONSTITUTION:Resonator 51 and 52 of different resonant frequencies are connected to coupling hole 61 and 62 provided on short-circuit face 1A which is vertical to the propagation axis of input waveguide 1, and different output waveguide 21 and 22 are connected to the other end of face 1A via coupling hole 71 and 72. Then the electromagnetic wave coming in from waveguide 1 and featuring frequency component f1 and f2 is introduced to resonator 51 and 52 through hole 61 and 62, and component f1 and f2 are resonated through 51 and 52. And resonated components are drawn out at waveguide 21 and 22 simultaneously through hole 71 and 72 in the form of frequency component f1 and f2.
