Patent abstract
Planar band pass filter includes several planar resonators (Ri) arrange parallely, such that the input (R1) and output (R5) planar resonators are connected to input (11) and output (12) feed lines, respectively, and the connections between the input (R1) and output (R2) planar resonators and the input (11) and output (12) feed lines are made by means of high impedance lines (14), respectively, such that the direction of propagation of the signal from the input to the output of the filter remains invariable between the feed lines, the high impedance lines (14), the corresponding resonators, and the rest of the filter resonators.
