Abstract :
The presented filter has two transmission poles and five transmission zeros. The mixed electric and magnetic coupling between two hairpin resonators, the tapped feeding position, and the source-load coupling configuration interacting on one another result in three transmission zeros in the vicinity of the passband. Two stubs added to the feeding lines contribute two additional transmission zeros beyond the passband.
