First, the size of the substrate integrated waveguide is designed according to the working frequency requirement, and then the microstrip SIW converter is selected to feed. The substrate integrated waveguide terminal is short circuited to form a standing wave. Then the position and size of the waveguide gap are roughly calculated. Finally, the model needs to be optimized through HFSS software simulation to get the final result.
