(54) MICROSTRIP BANDPASS COMB FILTER
(57)
FIELD: superhigh-frequency engineering. SUBSTANCE: filter has insulating substrate one of whose sides carries grounded base and other one, short-circuited strip conductors interconnected electromagnetically and conductively. Resonator conductors are straight; in addition, additional short-circuited strip conductors are deposited between strip conductors functioning as resonators and their sides are connected to adjacent resonators. Additional short-circuited strip conductors have variable length. EFFECT: enlarged operating passband of filter while retaining its specified electric strength. 1 dwg.
