BAND MICROWAVE FILTER Russian patent published in 2012 - IPC H03H1/00 H01P1/203 

FIELD: radio engineering.

SUBSTANCE: band microwave filter comprises U-shaped electromagnetically joined sections of microstrio lines opened at both ends with a permanent distance between sections of microstrip lines at the length of a communication area, to their extreme sections an input and an output lines are connected accordingly, at the same time side sections of odd U-shaped microstrip lines are arranged as irregular with the width of conductors, reducing from the edges of a communication area to the centre, and side sections of even U-shaped microstrip lines are arranged in the form of elements of identical width along the length of the communication area.

EFFECT: increased selectivity of filtration.
