Multi-channel waveguide structure

摘要

Slot transmission lines are formed in dielectric substrates. Several of such substrates can be stacked together. When stacked together, the conductive surfaces that form the transmission lines can be terminated in the same plane whereat the conductive surfaces form contact terminals. The co-planar contact terminals can be coupled to contact points on a circuit board. Signals on the circuit board can thereby be coupled into the slot transmission lines that extend through the dielectric substrates.
