Abstract
A high pass filter includes: an input-impedance-matching taper transition metal layer having an IMT input end and an IMT output end, the IMT input end having an IMT input end width, the IMT output end having an IMT output end width that is wider than the IMT input end width; a substrate integrated waveguide having a SIW input end and a SIW output end; and an output-impedance-matching taper transition metal layer having an OMT input end and an OMT output end, the OMT input end having an OMT input end width, the OMT output end having an OMT output end width that is wider than the OMT input end width. The substrate integrated waveguide is arranged such that the IMT output end is electrically connected to the SIW input end and such that the OMT input end is electrically connected to the SIW output end.
