MICROSTRIP FILTER Russian patent published in 1995 - IPC

FIELD: microwave devices. SUBSTANCE: device has dielectric substrate which one side is connected to conducting shield, another contains pieces of microstrip lines, which are directly connected in series. Microstrip stubs are connected to junction points of microstrip lines. Microstrip stubs, which are connected to same point, have electromagnetic coupling. Space between coupled stubs is filled with resistive material. Stubs that are connected to same junction point may have different electric lengths. More than two stubs may be connected to same junction point. EFFECT: increased functional capabilities. 3 cl, 2 dwg
