Abstract :
A novel concept for the transition between a microstrip line and a rectangular waveguide is presented and applied to a 42 GHz waveguide filter. Measurement results are presented which are in very good agreement to simulations. The waveguide is formed by soldering a U-shaped metallic filter part onto a RF-PCB (printed circuit board) using the board metalization as the last remaining waveguide wall. This technology is potentially enabling a fully automated SMD-assembly (surface mounted device) of waveguide components integrated into planar circuits.
