MICROSTRIP BANDPASS COMB FILTER Russian patent published in 2003 - IPC

FIELD: microwave frequency engineering. SUBSTANCE: filter has insulating substrate carrying on one side grounded base and on other one, short-circuited strip conductors that function as resonators, as well as additional strip conductors affording inductive coupling between resonators; conductors of its adjacent resonator are disposed on opposite side relative to additional open-circuit strip conductor that interconnects them and its sides are connected to adjacent resonators which are intercoupled conductively only. EFFECT: enhanced electric strength of filter at constant passband width. 1 cl, 1 dwg
