Reduced Coupling Aperture of Microstrip Stubs Provides New Aspects in Stub Filter Design

Abstract

Generally microstrip stubs are coupled galvanically over the whole cross-section of the adjoining main lines. Reducing the coupling aperture two effects can be observed being superimposed: Smaller coupling apertures lead to higher skirt selectivity, increase, however, the excitation of higher-order modes in the main lines. The resulting transmission… (More)
