Abstract
Various substrate-integrated waveguide (SIW) filtering crossover systems are described. An example SIW filtering crossover system may include: a substrate; a top metal plate placed on top of the substrate; a bottom metal plate placed beneath the substrate; a plurality of metalized via-holes in the substrate connecting the top metal plate and the bottom metal plate; and a plurality of grounded-coplanar-waveguides (GCPWs) coupled to sidewalls of the crossover system, wherein each of the GCPWs connects the crossover system to a respective microstrip line for signal transmission between the respective microstrip line and the crossover system.
