Zusammenfassung:FIELD: physics, radio. ^ SUBSTANCE: invention is related to radio electronics, in particular, to frequency selective facilities, and may be used in devices of radio signal frequency selection. Grounded bus of double-mode resonator communication is arranged in the form of meander, at that value of intersection between neighbouring pins (aperture W) periodically changes, taking two values: W1 (minimum) and W2 (maximum). Since interaction between symmetrical and antisymmetrical modes in this case is more intense than in prototype, filter passband is increased up to 0.15%. ^ EFFECT: increase of relative passband. ^ 8 dwg
