MICROSTRIP BAND-PASS FILTER Russian patent published in 2004 - IPC

FIELD: SHF equipment, selective paths of transceiving systems. SUBSTANCE: microstrip band-pass filter has dielectric substrate, which side carries grounded metallized base and which other side has strip conductors of two U-shaped resonators. One side of each U-shaped resonator is positioned between sides of another U-shaped resonator and is additionally coupled to its other side. Conductor of each mentioned resonator is connected with its center part to grounded base of section of strip line. EFFECT: increased attenuation in attenuation bands of filter, simplified staging of filter. 6 dwg
