FIELD: radio engineering.
SUBSTANCE: in strip-line filter containing insulating substrate suspended between screens and to both surfaces of which there applied are strip-line conductors of resonators, which are short-circuited on one side, between strip-line conductors of resonators on both sides of substrate opposite each other there arranged are additional strip-line conductors short-circuited to the screen on both ends.
EFFECT: decreasing overall dimensions and improving frequency and selective properties of narrow-band filter.
