LAMINATED WAVEGUIDE DIPLEXER

摘要

A laminated waveguide diplexer includes a first laminated waveguide, a second laminated waveguide, and a coupling metal connecting the first and second laminated waveguides. The first laminated waveguide has a first upper conductor with a first slot, and the second laminated waveguide has a second upper conductor with a second slot. The coupling metal includes a first line crossing over the first slot and a second line crossing over the second slot. In addition, the laminated waveguide diplexer further includes a first via connecting the first upper conductor and the first line, and a second via connecting the second upper conductor and the second line. The first and second vias are adjacent to the first and second slots, respectively, such that the first and second lines are short stubs for respective radio frequency signals propagating thereon.
