LAMINATED WAVEGUIDE DIPLEXER WITH SHIELDED SIGNAL-COUPLING STRUCTURE

摘要

A laminated waveguide diplexer includes an upper conductive layer having a first slot and a second slot; a first line crossing over the first slot; a first shielding conductor disposed over the first line; a plurality of first conductive pillars connecting the upper conductive layer and the first shielding conductor; a second line crossing over the second slot; a second shielding conductor disposed over the second line; and a plurality of second conductive pillars connecting the upper conductive layer and the second shielding conductor.
