Abstract (en)
[origin: DE19818947C1] the bandpass filter has three coupled rectangular hollow vol. resonators, two coupled via their narrow sides via at least one coupling aperture to a broad side of the third. A further inductive coupling aperture is arranged between the adjacent broad sides of the first two resonators immediately adjacent to their narrow sides contg. the inductive coupling apertures of the third resonator
