Webb13 dec. 2016 · Firstly, the SIW-based divider is used to feed the sixteen-element antenna. After that, the waveguide-based divider is used to feed two SIW-based dividers to avoid the use of long SIW branches. In this case, a waveguide-to-SIW transition is necessary between the SIW-based and the waveguide-based dividers.
